Our copending application Ser. No. 117,565, now U.S. Pat. No. 3,768,645, teaches a procedure for inspecting objects such as citrus fruit for internal flaws and damage by the use of beams of X-rays which are used in such a manner that they simultaneously scan the interior portions of the fruit on opposite sides of the fruit, and in which the emergent X-ray beams are caused to generate electrical signals which are used in the fashion described in the aforesaid application Ser. No. 117,565, now U.S. Pat. No. 3,768,645, which is hereby included herein by reference, to effect a mechanical sorting of the fruit into a multiplicity of grades related to the extent of internal damage sensed by the X-ray scanning.
We have now found quite surprisingly that our inventive system as set forth in the aforesaid copending application can be made to operate satisfactorily if for the X-ray beams there are substituted optical beams, that is, beams of electromagnetic radiation having a wave length of from about 300 to about 4,000 nanometers. It is surprising that the system can be made to operate satisfactorily with scanning beams of the type just described, since even though they are to be sure electromagnetic radiation even as are X-rays, nevertheless X-rays pass through objects of the general nature of fruit with some absorption and relatively little scattering, whereas light beams within the optical range recited are subject not only to greater absorption than X-rays but to a relatively larger degree of scattering, leading to the emergence of the optical beam in a greatly diffused form. In spite of these facts, we have found that if a sufficiently sensitive photoresponsive sensor is utilized on the emergent side of the fruit, the beam still retains enough of a directional character so that by the use of a pair of collimating apertures responses can be obtained which effectively differentiate between the transmissibility characteristics of the two opposite sides of the fruit which are subjected to the scanning optical radiation.
The present invention relates generally to apparatus and method for automatically inspecting objects and evaluating them according to an internal characteristic, and then separating the objects into groups according to the evaluated characteristic.
It is one object of the herein disclosed invention to provide improved inspection and sorting apparatus for citrus fruit, which embodies greater flexibility of operation than the heretofore known apparatus, and which is so designed that a high degree of accuracy will be obtained in the evaluation of a variety of internal damage characteristics, such as may result from frost, granulation, sunburn, blossom end decline, and other causes.
A further object is to provide improved and unique light inspection means and method for evaluating the internal damage of fruit, in which the fruit is substantially similarly oriented prior to inspection, so as to produce a more accurate evaluation of the fruit damage.
A further object concerns the provision of unique inspection apparatus for fruit, wherein the fruit is scanned by high intensity light beams on opposite sides of its core structure to produce electric signals which are determinative of internal meat tissue damage, and wherein the signals are introduced into an electric computer circuit which translates the signals into a percentage valuation of the fruit damage.
A further object is to provide apparatus of the herein described type in which optical fruit scanning signals are conducted to a computer circuit in which the signals are integrated and compensated for fruit size so as to produce a percentage indication of the internal damage of the fruit meat tissue.
Another object of the invention concerns the provision of apparatus in which optical damage sensors are operatively controlled by photoresponsive timing sensors so as to evaluate internal damage of the meat tissue of the fruit and eliminate errors due to skin portions of the fruit.
Still another object is to provide unique electronic computer means in connection with optical fruit inspection and separating apparatus, for integrating and evaluating the output signals of fruit damage sensors and classifying these evaluations into groups according to the percentage of damage to the meat tissue portions of the fruit, and upon movement of the fruit to a sorting station to automatically separate the fruit into the respective classified groups.
It is also a further object to provide improved apparatus for automatically inspecting and sorting a fruit, such as citrus fruit, wherein the fruits will be successively carried on a continuously moving conveyor past optical sensors at an inspection station en route to a sorting station, the sensors having their outputs connected with electrical means for evaluating the internal damage of each fruit in relation to damage classification groups, and wherein the group evaluation accorded to each fruit is stored in memory means until the fruit reaches a conveyor position at the sorting station to permit its discharge into the proper group corresponding to its predetermined group evaluation.
Further objects and advantages of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing one embodiment of the invention without placing limitations thereon.

FIGS. 6A and 6B are more detailed wiring diagram views of the circuitry shown in FIG. 5.
Referring more specifically to the drawings, for illustrative purposes, the present invention is shown as being embodied in apparatus as generally shown in FIG. 1 as comprising an inspection or detecting station A and a sorting or grading station B, which are in physically spaced apart locations, but are interconnected by means of a suitable conveyor C by means of which individual fruits 10 may be continuously and successively moved through the inspection station and thence to the sorting station where they are discharged into various grades depending upon the evaluated characteristics at the inspection station.
It will be appreciated that the apparatus may vary as to configuration and as to details of the parts thereof without departing from the basic concepts as disclosed herein. The inspection or detecting station A in general comprises a housing in which an upper compartment 11a houses a light source 12 arranged to project a beam 13 of light into a lower tunnel-like housing compartment 11b through which the fruit is conducted by the conveyor in a path which will intercept the light beam and associated internal characteristic sensors as generally indicated at 14.
The light generator 12 in its most generally applicable form may comprise any concentrated source of high intensity light radiation, such as for example a zirconium arc or a so-called quartz-iodine tungsten filament lamp. In order to increase the efficiency and to bring about an essentially collimated beam, when point or point-like sources of this type are used, we prefer to insert a condensing lens 70 in the path of the light beam as shown in FIG. 1.
We find best and prefer, however, to utilize a laser as the source of the light beams, which may be accomplished with a single laser as shown in FIG. 1A or with a pair of lasers as shown in FIG. 1B.
In FIG. 1A, the light beam emitted by the laser 71 passes first through a beam splitter 72 which may be a half-silvered mirror although we prefer the well-known arrangement in which the partially reflecting surface is incorporated at a right angle prism, as shown in FIG. 1A. A portion of the laser beam is emitted at right angles downwardly from the beam splitter 72, while another portion is reflected downwardly by mirror or prism 73, so that two parallel beams of approximately equal intensity result. The center-to-center separation of beam splitter 72 and reflecting prism 73 should be approximately the same as the separation of the collimating apertures 30--30 in FIG. 2, which will be explained in more detail below.
In the arrangement shown in FIG. 1B, two lasers 74 and 75 are utilized, which emit their beams downwardly, and which may be in parallel arrangement provided that the mechanical construction of the particular lasers employed permits them to be placed close enough together to match the separation of apertures 30--30. Where this is not possible or convenient, the two lasers 74 and 75 should be placed as close together as possible and beamed respectively at the two apertures 30--30.
Returning now to the conveyor, this may comprise an embodiment which is illustrated as incorporating laterally spaced chains or linkages 15a and 15b that are trained over suitable driving wheel means 16 and idler means (not shown) at the opposite end of the conveyor to separate the conveyor into upper and lower runs, the upper run passing through the housing compartment 11b. Each fruit 10 is preoriented prior to its reaching the inspection station, and is carried by a conveyor platform 17 which is swingably pivoted as by a pivotal support 18 at its leading end to the associated linkages 15a and 15b of the conveyor. The platform is normally held in a horizontal fruit transporting position against swinging movement about its pivotal support by means of a depending bracket 19 at the trailing end of the platform, which is adapted to normally ride upon an underlying rail member 20.
After passage of the fruit through the inspection or detecting station A, where it is evaluated with respect to its internal damage and classified as to its grade by means of an internal quality computer as will hereinafter be described in detail, the fruit is then carried to the sorting or grading station B where it will be automatically deposited at the proper grade separation position in the movement of the conveyor.
As diagrammatically illustrated in FIG. 1, the sorting or grading station B is arranged to provide for separation of the fruit into four grades, namely designated as G-3, G-2, G-1, and G-O, which are of progressively decreasing damage, the grade G-O being nondamaged fruit. At each grade position, means are provided for separately receiving from the conveyor C the respective fruits according to the grades as evaluated by the internal quality computer. Thus, at each grade position there is provided a chute or other conventional means for carrying the fruit away from the conveyor C. Preferably, such means comprises a movable conveyor belt, as indicated by the numeral 21, and which may be flanked by side walls 22 and 23 for guidingly retaining the fruit on the conveyor.
Provision is also made at each grade position for tilting the platform 17 so as to cause the displacement of the fruit thereon. One arrangement which may be utilized for this purpose is diagrammatically illustrated in FIG. 4 wherein there is provided at each grade position a pivoted rail section 20a, this section being swingably supported at its right end on a pivot 24. Normally, the rail section 20a is longitudinally aligned with the main rail portions 20, but may be swung in a clockwise direction to a raised position of its free end as shown in phantom lines upon energization of a connected actuating solenoid 25. In the raised position the rail section 20a functions as a camming member in the path of travel of a laterally projecting roller 26 carried by the depending bracket 19. The platform 17 is thus swingably deflected in a counterclockwise direction about its pivot 18 so as to discharge the fruit onto the associated conveyor 21. When the downwardly hanging platform reaches the end of the conveyor C, the roller 26 will engage a position restoring camming rail 27 (FIG. 1) which will cause the platform to assume a normal position during the lower run of the conveyor. The energization of the correct actuating solenoid 25 for depositing the fruit at its proper grade position is determined by the quality computer which will hereinafter be explained in detail. The non-damaged fruit of grade G-O will be carried to the conveyor end where it will be discharged onto a receiving chute 28 or other appropriate means such as a conveyor belt for guiding or transporting the fruit to a collection point.
As shown in FIG. 2, the sensors 14--14 are positioned below an opaque collimating plate 29 which is provided with spaced apart openings 30--30 that are positioned above the respective sensors so as to provide for the entrance of a light beam along each side of the fruit core portion 31 as the fruit is carried along a path of movement by the conveyor C.
As shown in FIG. 3, the collimating plate causes a light beam 13a to enter the sensor 14 positioned therebelow, each of the sensors comprising a photomultiplier tube 32 having an anode 33 and a cathode 34 (FIG. 6A) which forms a photosensitive surface positioned to receive incident light which is suitably diffused in an associated diffusion disc 35 of opal glass or other like material which will diffuse the incident light so that it impinges more uniformly on the photoemissive surface of the photomultiplier tube. As shown, the disc is secured to the end of the photomultiplier tube 32 by means of a retaining cap 36 or other suitable means.
The opaque collimating plate 29 as shown in FIG. 1 and in more detail in FIGS. 2 and 3 contains spaced apart openings 30--30 which may be of the order of 6 or 7 millimeters in diameter when the light beam from a point source is used as described earlier in connection with FIG. 1. When a laser or a pair of lasers is used, the essentially collimated beam or more properly to narrow pencil character of the optical radiation is preserved to a surprising extent, and in that event we may reduce the apertures 30--30 to of the order of 3 or 4 millimeters. The plate 29 should be at least as thick as the diameter of the apertures 30--30. In any case, the apertures 30 are of substantially smaller diameter than the photoreceptive surface of the photomultiplier tube 32, and in order to improve the response and to prolong the life of the latter we prefer to spread the radiation incident upon the photomultiplier tube over a larger area, which is readily accomplished by the interposition of a diffusion disc 35 between the aperture 30 and the receiving end of the photomultiplier tube. The diffusion disc 35 may comprise for example a piece of opal flash glass, or clear glass with either or both surfaces frosted. Alternatively, the diffusion disc 35 may comprise an optical filter, such as glass dyed so as to pass only certain wave lengths, with one or both outer surfaces frosted; or it may comprise an interference filter, again with an outer surface or two frosted. When a laser is used, an interference filter which has a narrow pass band for the wave length of the light provided by the laser is advantageous, since it reduces the effect of stray ambient light which, of course, should be excluded as much as possible in any case.
The diffusion disc 35 may also comprise a thickness of photochromic glass, which automatically darkens at high light intensities, so that the photoreceptor is protected against overload and damage when no fruit is interposed between the light source and the receptor.
Where the light source provides a continuous range of radiation, as is the case with a zirconium or like arc or a high intensity tungsten filament, the light will be mostly within the visible and near infrared regions. Citrus fruit being generally yellowish or orange-ish in color, the wave lengths towards the red end and particularly the infrared end of the spectrum are transmitted through the fruit with the least scattering and least absorption, so that in this case, for the case of citrus fruit, it is advantageous to utilize a yellow, orange, or red filter as part of the diffusion disc 35.
When a laser is used, the common and readily available helium-neon laser is well suited for the purposes of the invention, and its wave length of 633 nanometers is well adapted for citrus fruit. However, other wave lengths may be used as, for example, the commonly available infrared lasers emitting at 1152 and also at 3391 nanometers. Of course, care should be taken particularly when infrared radiation is employed for the scanning to utilize a photomultiplier having good sensitivity to the wave length in question. Other photoreceptors may be used, especially those adapted to infrared radiation.
The same piece of fruit can advantageously be successively scanned at two different wave lengths. The difference in response is itself diagnostic of internal damage in many cases.
The operation of photomultiplier tubes is well known in the electronic field. Briefly, the cathode electron current is amplified and utilized to produce a photomultiplier output voltage which is characteristic of the fruit light absorption. For proper operation, the anode current is set at 10 microamperes in the open light beam by varying the high voltage bias on the photomultiplier tube.
Since the skin portion of the fruit has different absorption and diffusion characteristics than the meat portion, it will be appreciated that in many cases a large output voltage signal will be supplied by the photomultiplier tube as the damage sensors pass from the skin portion of the fruit to the meat portion thereof. It is, of course, desirable to eliminate the error caused by such a signal, and to begin the damage evaluation period after the damage sensor has left the skin portion and entered the meat portion of the fruit, and to end the evaluation period before the sensor again enters the skin portion as the fruit progresses past the light beam.
Elimination of such errors is accomplished by using two timing sensors 37 and 38 which are positioned as shown in FIG. 2 so that one will be ahead of the damage sensors and the other will follow the sensors in the path of movement of the fruit. The timing sensors are supported for adjustable movements in the plate 29 as by means of manually operable screws 39--39 which provide for independent adjusting movements of each timing sensor. The timing sensors are utilized in connection with a timing circuit, which will be discussed later in detail, to obtain timing signals for coordinating certain operating phases of the internal quality computer. Briefly, the timing sensors comprise a pair of silicon photodiodes 40 and 41 (FIG. 6A). These diodes are connected in parallel and arranged in a circuit to provide a voltage output signal such that when the skin portion at the leading end of the fruit covers one sensor, the output voltage will be cut substantially in half, and when both sensors are covered, the output voltage will be substantially zero. The spacing between the diodes, as indicated at a, will be substantially equal to the fruit skin portion average thickness at its leading end and trailing end, respectively, as indicated at b.
Referring more specifically to the schematic block diagram of FIG. 5 and the detailed circuitry as shown in FIGS. 6A and 6B, the details of the internal quality computer and associated timing means, for evaluating the fruit damage and separating it into predetermined grades according to such damage, now will be described more fully. As will be observed, the two photomultiplier tubes 32--32 of the respective internal characteristic sensors are connected to provide inputs to similar damage evaluating circuits 42 and 43 which are connected to the anodes 33--33 respectively of the photomultiplier tubes 32--32. These tubes have their cathodes 34--34 connected with the ends of a suitable control potentiometer 44 having a movable contact 45 connected with an appropriate high voltage source shown as comprising -600 volts which provides for an appropriate bias adjustment for obtaining the desired anode current setting. The ends of the potentiometer are connected across a resistor 46 having its midpoint connected to an electrostatic shield according to general practice. The output voltage, as indicated at 47, is in each case fed to an input or preamplifier 48. Since the two previously mentioned evaluating circuits 42 and 43 contain similarly connected components, it is believed that the detailed description of only one of these circuits will be necessary for a proper understanding of this portion of the computer.
Thus, in the evaluating circuit 42, the preamplifier 48 is provided to isolate the output of the internal characteristic sensors and amplify the output voltage of the connected photomultiplier. This preamplifier includes a conventional basic amplifier component A1, with the resistors R1 and R3 forming a feedback path that sets the stage gain to approximately 10, and the capacitor C1 reducing the stage gain to unity at high frequencies.
The output from the preamplifier 48 is connected through a resistor R5 with the input to a noise filter circuit 49 which will eliminate high frequency noise signals that do not relate to fruit damage. This low pass filter circuit utilizes a conventional basic amplifier component A3. A capacitor C5 and resistor R7 are connected in parallel to form a feedback path which operates in conjunction with the resistor R5. A resistor R9 and capacitor C3 operate to make the amplifier gain decrease 12 db/octave above 250 Hz.
The output of the noise filter 49 feeds a logarithmic amplifier circuit 50 which is utilized to compensate for the absorption characteristic of the fruit, in such a manner that a change due to damage will cause the same output for a small fruit as a for a large fruit, and wherein the output voltage increases upwardly toward +10 volts. This circuit utilizes a conventional basic amplifier component A5 having a balance control resistor R11 which is adjustable for eliminating the amplifier offset output voltage. A resistor R13 is connected in a gain control circuit which is adjustable for the exact logarithmic transfer characteristic.
The output of the logarithmic amplifier circuit 50 connects with a high pass filter circuit 51 which is utilized to eliminate low frequency signals caused by drift errors, fruit shape irregularities longer than 0.2 inches, and differences in thickness from one side of the fruit to the other. This circuit utilizes a conventional basic amplifier component A7, and a capacitor C9 and resistor R17 provide a feedback path which operates in conjunction with a capacitor C7, capacitor C11 and resistor R15 so as to make the amplifier gain decrease on the order of 12 db/octave below 75 Hz.
The outputs from the two high pass filter circuits 51--51 of the evaluation circuits 42 and 43 are fed into a common difference amplifier circuit 52 which subtracts the two filtered and compensated output signals from the evaluation circuits 42 and 43. This output corresponds to the difference between the evaluation on one side of the fruit core and the evaluation on the other side for small anomalies. A good fruit will have few anomalies and the output will be relatively small. A bad fruit will have an output consisting of many large pulses. The difference amplifier circuit 52 utilizes a basic amplifier component A9 which receives the separate input signals through resistors R19 and R20 respectively. Resistors R21 and R22 are utilized to set the difference gain to approximately 7. The capacitors C13 and C14 provide an AC feedback to decrease gain at frequencies above 500 Hz.
The difference amplifier circuit 52 feeds into a gain adjustment amplifier circuit 53 which is utilized to adjust and vary the gain for different types of internal damage from a control center. For example, investigation and tests indicate that fruit granulation will require a higher gain setting than frost damage. The gain or damage sensitivity amplifier circuit 53 utilizes a basic amplifier component A10. A DC feedback having a resistor R24 therein sets a constant amount of feedback. A variable input resistor R23 provides an adjustment which allows the stage gain to be varied substantially from 1 to 10. A capacitor C15 paralleling the resistor R24 provides an AC feedback which operates to reduce noise at high frequencies.
Output from the gain adjustment amplifier circuit 53 is fed to an absolute value amplifier circuit 54 which utilizes interconnected basic amplifier components A11 and A12. The amplifier A11 operates as a unity gain inverter for positive signals only. A diode D1 makes the gain substantially zero for negative input signals. The amplifier A12 is utilized as a summing amplifier with respect to which a resistor R28 sets a constant DC feedback. A resistor R27, which is connected in series with resistor R28, makes the gain of amplifier A12 equal to 1 for input signals received from the gain adjustment amplifying circuit, while a resistor R29 makes the gain of the amplifier A12 equal to 2 for signals received from the amplifier A11. The output of the absolute value circuit 54 is the absolute value of its received input and comprises the instantaneous magnitude of the difference in thickness of the two halves of the fruit lying on opposite sides of the fruit core.
The absolute value circuit 54 (FIG. 6A) is shown as being connected through a conductor 55 to an input resistor R37 (FIG. 6B) of an integrator circuit 56. This circuit integrates the received absolute value signal over the period when the fruit is being moved by the conveyor over the sensors 14. The final value of the integration is the area under all of the absolute value output pulses. This value will be much larger for a bad fruit for the reason that there will be more pulses and these pulses will be larger than for a good fruit. The integrator circuit 56 includes a basic amplifier component A13 which is controlled by means of an electronic switch S1 connected to receive a control voltage signal from the voltage output terminal V2 of the timing circuit (FIG. 6A) in such a manner that the integrated output will be for the time that the sensors are evaluating the meat portion of the fruit. When the electronic switch S1 is open, a capacitor C18 will be charged at a linear rate determined by the output of the amplifier component A12 and resistor R37. When the switch S1 is closed, resistors R38 and R39 function to maintain the output of the amplifier component A13 at 0 volts. A capacitor C19 prevents overshoot in the output of the amplifier component A13 as the switch changes from open to closed position.
A ramp generator circuit 57 is provided to produce a ramp wave form which may be varied to provide for fruit size compensation in order to obtain maximum system accuracy for any given lot of fruit. Although the system is designed to grade fruit from 2 inches in diameter to 6 inches in diameter, small fruit can be graded more accurately if the size compensation is adjusted to allow for the maximum size to be run. Specifically, the ramp generator utilizes a basic amplifier component A14 which is controlled by an electronic switch S2 in an integrator circuit similar to the integrator circuit 56. A resistor R31 provides for central control adjustment and with a resistor R32 forms a voltage divider which sets the input to a constant DC level. When this input is integrated, it becomes a ramp wave form as a capacitor C17 is linearly charged. Resistors R35 and R36 constitute a voltage divider which establishes the output of the amplifier component A14 at substantially -0.5 volts when the switch S2 is closed.
The outputs of the integrator circuit 56 and the ramp generator circuit 57 are fed into a divider circuit 58 comprising a basic divider component DV1 which functions in a well known manner to divide the output of the integrator circuit 56 by the output of the ramp generator circuit 57. Since the integrator output is proportional to the total amount of damage in the fruit, and the output of the ramp generator is proportional to the size of the fruit (diameter), the resulting quotient will be in terms of percentage damage. That is to say, that the divider output is proportional to the total amount of damage contained in a very thin slice of the fruit divided by the length of the slice. In its broad concept, it is conceivable that as an alternative to utilizing a ramp function as the divisor, it may be necessary to use a parabolic function in order to compensate for the area instead of diameter.
A sample hold amplifier circuit 59 receives the output of the divider circuit 58, this output being of a wave form as indicated at 60. The purpose of the sampe hold circuit is to hold the final size compensated output value of the divider, until the next fruit traverses the internal characteristic sensors 14, and thus provide a prolonged output signal as indicated at 61. This circuit embodies a basic amplifier component A15 which is controlled by an electronic switch S3 operatively connected to receive energizing voltage from the voltage terminal V1 of the timing circuit. The amplifier A15 is a unity gain amplifier with a resistor R41 in a feedback connection and a resistor R40 connected to the amplifier input. When the switch S3 is closed, a capacitor C21 will be charged to the amplifier output voltage. When the switch S3 is in opened position, the input signal is removed and the amplifier output remains at the voltage across the capacitor C21 which will be retained without significant decrease for several seconds. A capacitor C20 is utilized to reduce the amplifier gain, when the frequency is above 500 Hz.
A switched amplifier circuit 62 is provided for switching the output of the sample hold amplifier 59 so as to be turned on during its hold period, and off during the sample period as indicated by the output signal wave form 60 of the divider circuit 58. This circuit utilizes a basic amplifier component A16 which is controlled by an electronic switch S4 connected with the voltage terminal V2 of the timing circuit. When the switch S4 is closed, the amplifier functions as a unity gain amplifier. When the switch S4 is opened, feedback through a resistor R45 drops to zero and the amplifier output becomes zero. Thus, the output of this amplifier circuit occurs only during the hold period.
The output of the switched amplifier circuit 62 is fed as an input to a grade separator circuit 63, which basically comprises three voltage comparators, each of which has a variable threshold voltage. As will be seen, the switched fruit characteristic evaluation signal from the switched amplifier circuit 62 is fed through input resistors R46, R47, and R48, respectively, to basic amplifier components A17, A18, and A19 of the three voltage comparators. The threshold voltage for the respective comparators for the grades into which the fruit is to be separated, is determined and set by resistors R52, R53, and R54 and respectively fed to the amplifiers through resistors R49, R50, and R51. When the input is larger than the threshold voltage of one of the comparators, the connected diode D8, D9, or D10 will be reverse biased and its associated amplifier output will switch from 0 to -8 volts. This output voltage is fed to the other amplifiers through the respective diode-resistor combinations D5-R55 D6-R56, and D7-R57 to prevent more than one comparator output being supplied to the respective output terminals G-3, G-2, and G-1 at the same time.
With the circuit arrangement as just described, it will be observed that if the input is below the threshold voltage of amplifier A19, as set by resistor 54, then none of the amplifiers will be energized and all of the comparator outputs will be zero. If the input is above the threshold of amplifier A19 but below the threshold of amplifier A18, as set by resistor R53, then amplifier A19 will be energized and an output of 8 v. will appear at the G-1 terminal. If the input is above the threshold of amplifier A18 but below the threshold of amplifier A17, as set by resistor R52, then the amplifier A18 will be energized and an output of 8 v. will appear at the terminal G-2. This output voltage is also fed back to amplifier A19 so as to deenergize it. A similar operation occurs when the input is above the threshold of amplifier A17, and the output voltage will appear at the G-3 terminal. The absence of an output voltage at any of the terminals G-1, G-2, or G-3 indicates that the fruit has a damage evaluation which is below that of fruit having the least damage as selected for grade G-1.
The internal quality computer and sorting or grading of the inspected fruits as heretofore described is controlled and coordinated by timing circuitry which will now be described, and which is connected to the output furnished by the photodiodes 40 and 41 (FIG. 6A). The timing sensor diodes are connected to the input of a preamplifier circuit 63 having a basic amplifier component A20 which is coupled with a voltage divider formed by resistors R57 and R58, this voltage divider being connected to provide normally a reverse bias on the photodiodes 40 and 41. The sensor signal is coupled to the amplifier component A20 by a capacitor 25 and a resistor R60. Resistors R59 and R61 form a feedback path that sets the amplifier gain to approximately 5, and the parallel connected capacitor 24 is utilized to reduce the gain to unity at high frequencies.
A timing offset adjust circuit 64 is provided for adjusting the voltage timing level. This circuit includes a basic amplifier component A21 which has its input connected with a DC voltage determined by a variable resistor R64 which may be mounted on a central control panel and varied to compensate for variations of skin thickness of the fruits being tested. The voltage determined by the resistor R64 is added to the timing signal received from the preamplifier circuit 63, through a resistor R63. As shown in the representative output curve 65, the skin compensation control is adjusted so that the points X--X on the wave form will be at zero volts. The integrator 56 will then be turned on after the fruit has started across the damage sensors and before it has finished.
The output from the timing offset adjust circuit 64 is then fed through a voltage comparator circuit 66 which operates as a timing switch circuit. This circuit includes a basic amplifier component A22 connected to receive its input from a resistor R66, and the input current will function to establish a circuit through either the diode D3 or the diode D4 depending upon its polarity. The amplifier output will be -8 v. when the input is greater than zero, and +8 v. when the input is less than zero. Resistors R68 and R70 operate to clamp the output voltage to -8 v. when diode D4 is conducting, and resistors R67 and R69 operate to clamp the output to +8 v. when the diode D3 is conducting. Therefore, the voltage appearing at the terminal V1 will reflect the polarity changes of the output voltage.
The output from the voltage comparator circuit 66 as just described leads to a time delay circuit 67 which is utilized to invert and delay the output of the voltage comparator circuit so that the switch S3, which is connected to the terminal V1, for the sample hold circuit 59 can be switched to its on position slightly before the switch S1, which is connected to the terminal V2, of the integrator circuit 56 is actuated to an open condition. Resistors R71 and R72 of the time delay circuit are utilized to set the DC gain to 1, while the significant time required to charge a capacitor C27 provides the time delay between the input and the output of this circuit.
It is an important feature of the present invention that once the percentage damage is evaluated for a certain fruit, this information will be stored until that fruit during its transport by the conveyor C reaches a point at the sorting or grading station B where it is to be transferred or discharged into the proper group corresponding to its predetermined group evaluation. For such purpose, an electronic shift register circuit 67 (FIG. 5) is connected to each of the outputs G-1, G-2, and G-3 of the grade separator 63. The shift register is of conventional construction and has a memory cell for each fruit position between the inspection station A and the point where the fruit is to be transferred at the sorting station B. As each fruit moves through the inspection station, the information in each shift register is shifted from one memory cell to the next, thus keeping step with the fruit movement. The shifting operations are accomplished in each shift register by switching means which are synchronized with the passage or conveyance of the fruit through the inspection station and may comprise a voltage signal obtained for example from the terminal V1 of the timing circuit or other synchronized pulse generating means 68, as exemplified by such known devices or mechanisms as an optical shaft decoder, a micro-switch mechanically actuated by a rotating shaft, switch pulsing means magnetically actuated in response to shaft rotation, or other suitable means. When the fruit reaches the proper separation point, the shift register functions to energize its associated solenoid 25 to actuate the mechanism for tilting the fruit conveyor platform 17 to discharge the fruit thereon into the appropriate receiver for that particular group as previously explained. The undamaged fruit which is not discharged at the G-1, G-2, or G-3 stations will be carried by the conveyor and discharged at the G-0 station, this being the undamaged and most acceptable of the inspected fruit.

In The Odyssey, how do the suitors get weapons in the final battle scene?
1 Answer | Add Yours
In The Odyssey, the suitors in the final scene are cut off from the weapons originally. When Telemakhos returns to the storage room to get more weapons, he accidentally leaves the door open. Melanthius, a disloyal goatherd, runs to room and gathers weapons to pass out to the suitors. On his second trip to the room, he is caught by Eumaeus (swineherd) and Philoitius (oxherd). Remember, the other two herders are on Odysseus and Telemakhos's side. This further emphasizes their loyalty and goodness while it puts Melanthius on the same level as the suitors. Odysseus and Telemakhos's ability to kill the suitors even after they are armed characterizes them as physically as well as morally superior to the other suitors.

Drinking Water: Almost a quarter (23.6%) of households in the region use the river, stream, pond or lake as their main source of drinking water. While 23.0 per cent use the well, 19.4 per cent rely on pipe-borne water located outside the premises and an additional 8.8 per cent use pipe borne water located within the house for their supply of drinking water. At the district level, Fanteakwa has the highest proportion (54.5%) of households that draw drinking water from the river, stream, pond and lake.On the other hand, New Juaben has the highest percentage (39.0%) of households whose source of main drinking water is pipe-borne, located within the premises and 29.9 per cent with pipe-borne water located outside the premises. Notwithstanding the availability of the basic infrastructure for pipe-borne water in the New Juaben municipality and other urban centres, water is woefully inadequate for the use of households and is a source of constant concern for the District Assemblies.The volume of treated water is inadequate and the distribution system is inefficient. Schemes on the drawing boards of the District Assemblies should have priority of implementation to ameliorate the situation.LightingThe kerosene lamp is the main source of lighting in the region, used by 64.3 per cent of households. Apart from the kerosene lamp, electricity is the second major source of lighting in 34.3 per cent of households. For the districts, Afram Plains has the highest proportion (89.5%) of households using kerosene lamps as the main source of lighting compared with New Juaben which has the highest proportion (77.6%) of households using electricity for lighting.Fuel And Space For CookingAbout 70.0 per cent (68.8%) of households use wood and 22.0 per cent use charcoal as the main fuel for cooking. The District Assemblies have, as a matter of serious concern to consider introducing L.P. Gas cylinders of different sizes to encourage the use of L.P. Gas as the main source of cooking fuel in the region. In the long run, charcoal is more expensive than L.P. Gas, but it can be bought in smaller quantities when needed.Wood as cooking fuel is highest in the Fanteakwa District (89.5%); compared with the regional average of 68.8 per cent. The use of charcoal as a cooking fuel is highest in the New Juaben municipality (52.4%) compared with the regional average is 22.0 per cent. This can be explained by the fact that charcoal, processed from wood, is more affordable in the urban setting and that wood is more accessible in the rural areas, than in the urban. With such a high proportion of households (90.8%) using wood and charcoal as their main fuel for cooking, there is a serious threat to the environment, in particular its consequence on the depletion of forests.Cooking SpaceNearly two in five households (37.9%) have separate rooms exclusively set aside for cooking purposes. At the district levels, the Afram Plains District has the highest percentage (46.1) of households who have a separate room set aside exclusively for cooking.Bathing FacilityAbout a third (31.7%) of households in the region use a shared bathroom; a quarter (24.1%) own a bathroom for their exclusive use; about a fifth (18.0%) share open cubicles, and slightly more than a tenth (11.8%) have open cubicles for private use in addition to 4.0 per cent using a bathing facility in another house.Toilet FacilityOver a third (37.5%) of households in the region use pit latrine in their house, while 29.8 per cent use public toilets of all kinds (pit, pan, KVIP and W.C), In the districts, the Fanteakwa District has the highest proportion (58.9%) of households that use a pit latrine.
The New Juaben municipality has the highest use of the W.C. (17.7%) and of public toilets (39.5%). It is noteworthy that only 5.4 per cent of dwelling units in the region have no access to an accepted toilet facility, compared with the national average of 20.0 per cent. In the districts, households with no toilet facility range from 1.2 per cent in the New Juaben municipality to 28.6 per cent in the Afram Plains District.Solid Waste DisposalMore than half (56.5%) of households in the region dispose of solid waste in public dumps, while a quarter (25.2%) dump their household waste anywhere. A tenth (10.1%) of households bury their solid waste in and around their compounds. The vast majority of households in the districts for example Birim South (72.5%), New Juaben (70.0%) and West Akim (66.3%) districts dispose of their solid waste in public dumps, Almost half (48.9%) of the households in the Afram Plains District and 40.6 per cent in the Fanteakwa District, dump solid waste elsewhere, a practice which can impact negatively on the environmental sanitation condition of residents.Liquid Waste DisposalOnly 2.0 per cent of households dispose of their liquid waste through the sewerage system. The large proportion (48.2%) of households dispose of their liquid waste by throwing such waste onto the compound, while other households throw liquid waste onto the street, outside (31.6%) or into the gutter (17.8%).Within the districts, households in the Afram Plains (78.0%), Fanteakwa (68.8%) and Manya Krobo (58.2%) districts have the greatest tendency to throw liquid waste onto the compounds compared with households in the New Juaben municipality (25.2%).
The practice of households throwing liquid waste onto the street is least in the Birim South (41.8%), Birim North (39.3%) and Suhum-Kraboa-Coaltar (39.3%), districts.

Transfer Credit
Current Lawrence students may incorporate work taken at other institutions for credit towards their Lawrence degree. To do so, approval by the Faculty Subcommittee on Administration (preferably in advance of enrolling in another program) is required. It is greatly to your advantage to know in advance that the credits you earn will be applicable to your degree. Not all courses or programs of study offered by other institutions will be accepted for credit at Lawrence.
Students who will attend a Lawrence affiliated off-campus program (those listed in the current course catalog) do not need to petition for transfer credit. Credit for these programs will be automatically transferred to a student's record when the Registrar's Office receives a grade report from the program.
New transfer students do not need to petition for transfer credit from their former institution. The registrar will provide transfer students with an evaluation of their previous work which will describe the courses accepted and the requirements to be completed in order to earn a degree from Lawrence.How To Petition for Transfer Credit:
- Procure catalogs or summer school bulletins from the schools you are interested in attending. It is recommended that you try to obtain a syllabus for each course you are considering. At the very least, you must submit a description for each course you wish to be approved.
- Obtain a petition form(s) for the faculty subcommittee on administration. These are available in the registrar's office, academic building offices, and from the dean of student academic services.
- Your petition statement should indicate you are petitioning for transfer credit and include the specific course (title, number, department, program if appropriate, and institution) for which you are seeking approval. If you wish the credit to fulfill a particular general education requirement, state that as well. Please NOTE: Transfer credit may not be used to fulfill the writing- or speaking-intensive requirements. The appropriate academic department must determine if a transferred course will complete a requirement for a major, minor, or interdisciplinary area.
- Use the remarks section to indicate the amount of course credit in semester or quarter hours awarded by the institution/program for completion of the course, and when you intend to complete it. If the course will be taken during a summer session, please indicate the number of weeks in the session and the number of hours of participation (class, laboratory, field, or studio). Usually no more than two courses will be approved for six or eight week sessions.
- Attach the course description, and syllabus if you have one, to the petition form and:
- obtain your adviser(s) comments and signature,
- obtain the comments and signature of the chair of the department in which the course would be given if the course were offered at Lawrence.
- Submit the completed petition form to the registrar or to the dean of student academic services for review by the Faculty Subcommittee on Administration. You will be notified by memorandum of the action taken by the subcommittee. The subcommittee generally meets once a week when classes are in session.
Upon completion of the course or program, you must have an official transcript of your work sent to the registrar before credit can be awarded. Transfer credit is normally awarded on the basis of 3-1/3 semester, or 5 quarter, hours for 6 Lawrence units. For example, 3 semester hours are equivalent to 5 Lawrence units. Only courses in which you earn a grade of "C-" or better will be awarded credit. If you take a course on an "S/U" or "pass/fail" basis, the registrar must be able to verify that you earned an equivalent grade of "C-" or better before the course can be accepted for credit. The grade(s) you earn will be used in the computation of your composite grade point average. Application of transfer course credits to major requirements is determined by the appropriate academic department.
IF you are a senior within three terms of completing your degree and have not yet completed your major requirements, you must petition the faculty subcommittee on administration for a waiver of the senior residency requirement.
IF you are a senior and intend to complete your degree at the end of the term in which you will be off campus, please check with the registrar regarding the deadline for receipt of an official transcript of your work.
IF you are receiving financial aid from Lawrence, you should inquire about the availability of financial assistance from the program/institution you plan to attend. Lawrence does not provide financial aid to students attending non-Lawrence programs.

Jackett resigned on Tuesday after six-and-a-half years at The Den, saying he felt it was time for a new challenge.
Palace had battled to a goalless draw with Millwall seven days earlier and Holloway admitted he had no idea Jackett was thinking of leaving.
"I had a drink with him after the game on the Tuesday night and there was no indication he was feeling like that at all," said Holloway.
"But he was the longest-standing manager and the atmosphere down there, worrying they might go down, was really tense.
"Maybe he feels he needs a change. It's been nearly seven years in one place and after getting to the semi-final of the FA Cup, maybe he's had enough.
"But looking back at his time there no-one could deny how well he has done."

I'd been toying with the idea of taking some anniversary photos with the Huz but had no clue how I would choose from all the great photographers out there. Then I discovered Unusually Fine Photography--a wedding, engagement, and portrait studio--and all I could think of was teleporting to New York for a shoot with the ultra-talented Max and Margaret. But the time/space continuum being what it is, I've settled for the next best thing--an exclusive interview with this amazing duo!
Tell me about the birth of Unusually Fine. It's a funny story, that. We met at a Boston T stop and after a short but steamy courtship realized we would be best friends always. We are both passionate about photography, fashion and books. We collaborated on a fine art project and had so much fun making photographs that we decided going into business together was maybe the best idea ever.
What makes Unusually Fine photos, well, unusually fine? In a word, us! We put into every wedding the same thought and planning we'd put into a fashion shoot. That's how we make our subjects look so glamorous. We always work weddings as a team, which makes for extraordinary coverage and value. And we use the best equipment, latest technology, and the finest prints and books.
What are some favorite art and design influences that inspire and inform your work? Margaret finds inspiration in places like W Magazine, Wong Kar-wai movies, and blogs such as ffffound.com. Max is big on old Hollywood, Gerhard Richter, and (yup) Lady GaGa.
The incredibly private moments you capture make me blush and tingle at the same time. How are you able to get your subjects to disarm so completely for the camera? Our work attracts fun and interesting couples! And we get to know our clients before the wedding, so when the big day arrives we're already pals. This intimacy allows us to mix easily and capture those candid moments that tell the story best. (P.S. Max thinks Margaret is very disarming.)
Thanks to Max and Margaret for sharing with us! And honestly, these tiny images don't do justice to Unusually Fine's pulse-racingly-good work, so you've got to check out their website and hilarious blog. Plus if you're a bride-to-be with an upcoming wedding in New York state, I'm officially jealous: you can enter to win Unusually Fine's services for your wedding day! Now if you'll excuse me, I'm off to buy matching his 'n' hers striped shirts :)
P.S. Speaking of winning, don't forget to enter this morning's giveaway for Jamie Oliver's latest cookbook!

SERS for diagnostic applications
Raman spectroscopy enhanced by nano-sized gold structures has been used by researchers in Italy to detect prion protein – PrPc – and to monitor in vivo the PrPC-Cu(II) interaction, giving reliable indications about the conformational status of PrPc protein in different cell lines.
Combined green hydrothermal synthesis and thermal annealing yields the optimal SERS substrates for amplifying the Raman signal preserving the condition of biological material.
The scientists have analysed the binding of copper ions to PrPC molecules on living cultured cells and highlighted a close relationship between the expression of prion protein and the intensity of Raman peaks.
The study points towards the possibility of unravelling and quantifying prion protein expression in complex biological samples by the application of an external stimulus, which has the potential to both speed up and reduce the cost of detecting prion protein.
A full description of the work can be found in the journal Nanotechnology.

.30 Caliber/7.62mm (.308) 110 gr. HPThere is only one 30 caliber Varminter rifle bullet in Sierra's line. This 110 grain #2110 Hollow Point also is the largest caliber Varminter bullet in Sierra's line. It will withstand exceptionally high velocities and can be loaded in all 30 caliber cartridges, including magnums. It is extremely accurate and has been used by some Hunter Benchrest competitors. It offers explosive expansion on varmints and small game at velocities achievable with the full range of 30 caliber cartridges. This is an ideal bullet to choose for off-season practice on varmints with any 30 caliber hunting rifle.
In handguns, Sierra's Hollow Point construction in the 110 grain #2110 bullet guarantees expansion, even at moderate velocity levels. Expansion will not be explosive but is acceptable for varmints and small game. Capable of extraordinary accuracy, this is an excellent light bullet for most 30 caliber single shot pistols.
The #2110 was introduced in 1958.

|Started loading this bullet in my 30.06 for varmints such as coyotes and ground hogs, when I was in my 20's I am 76 years old today. One dear season I grabbed them by mistake and went deer hunting with them have used nothing else for deer since then.

|Initial testing in my Remmy SPS Varmint 26" 308 shot a nice 0.5 MOA node at 48.3gr of 2208, should get that down a little more with more testing/tweaking. Good price per 100 too, should make a great varmint load. Cheers

|Bought by mistake, but tried them in a 30 Carb. with 14.0gr H110. How neat they were, good penetration, accuracy better then expected with a Carbine. 1 1/2 inches at 100 yards. Couldn't ask for more from a mistake.

The Jamband Velvet Underground: Col. Bruce Hampton and the Aquarium Rescue Unit
In February 1992, the reunited Dixie Dregs arrived at New York's Ritz and I was excited to check them out. Though I had always considered their music somewhat sterile if brilliantly constructed, I recognized Steve Morse as a stellar guitarist. So as a young music magazine editor, I was anxious to expand my musical scope and appreciation and Steve was someone that I thought I should better understand. Publicist Marc Pucci pushed me to get there early to see the opening act—the oddly named Aquarium Rescue Unit.
He assured me that the newly reformed Capricorn Records was very excited about the band, led by a longtime Atlanta cult hero, Col. Bruce Hampton (Ret.). Still pinching myself over living in New York City, working at a major music magazine and having publicists ask me to go to shows, I earnestly arrived at the Ritz close to start time in order to check out this band with an open mind but with few expectations. They had just started when I walked into the half-filled Midtown Manhattan ballroom and strolled right up to the lip of the stage, immediately astounded by what was unfolding.
A skinny redheaded guy with a beard was hunched over a Stratocaster, dispensing lightning fast licks that danced the razor's edge I love, where everything could fall apart at any moment, though his sure-handed playing and obvious blues rooting made that highly unlikely. To his right, a handsome young man was grinning, eyes cast toward the sky as he worked a six-string bass with the same mix of skill and abandon, sometimes scatting along to the notes he played. On the other side of the stage, a dark-haired guy with bushy eyebrows was blasting out supercharged bluegrass licks on a Mandocaster, a mandolin in the shape of a mini Telecaster. A brilliant drummer was laying down beats from enough angles to replicate at least two percussionists. Overseeing the whole thing was a crazy little man with a handlebar moustache playing some kind of demented short-scale instrument I would later learn he called a Chazoid. He sang like a bastard child of Bobby Bland and Hazel Dickens and occasionally played wicked, inspired licks. This was obviously the Colonel. He was clearly the ringmaster of this nutty circus, which radiated light and the spark of life and was hilarious without being a joke.
Questions bounced around my racing mind: Who was he? What was this? Why wasn't everyone talking about this fabulous band? I pushed them all down and out because I wanted to stay in the moment. I'd like to tell you how the rest of the crowd reacted, but I have no idea. I wasn't looking around, solely focused on the stage, experiencing something that I have just a handful of times—musical nirvana that hit me in the head, heart and guts at the same time and was all the more powerful for being so completely unexpected.
After the show, I watched the musicians break down their own gear and caught guitarist Jimmy Herring's attention, introduced myself and told him I'd meet him downstairs. I had been invited to a meet and greet, which I had originally planned on stopping by just long enough to see whether or not they had free beer, but my plans had changed.
In a little room downstairs, I chatted a bit with Bruce and spoke at length with Jimmy. We were both somewhat starstruck. Jimmy was thrilled that a Guitar World editor had so enjoyed his playing. I was gobsmacked that someone like him cared what I thought, and convinced that I had just discovered a major talent. I was right, of course, and as silly as Jimmy's excitement seemed then and still seems now, it was revealing about both his nature and the group's circumstances.
"We were making $92 a week and sleeping in one room," Hampton told me recently. "After two years, we got two rooms and we were so ecstatic, we had a celebration. There were five of us in a Chevrolet van with 400,000 miles on it. How we did it, I'll never know, but I never had more fun or made greater music than I did during that run."
No wonder Jimmy was so happy that I had taken note of this brilliant musical circus—they were playing for love and for each other and I was an outsider acknowledging their instincts were right, that they were onto something. There is no greater satisfaction for an artist than some affirmation that their struggling is not for naught, something they had received precious little of outside their Atlanta base.
This incarnation of the band played together for about two years. Bassist Oteil Burbridge and drummer Jeff Sipe (then called Apt. Q258) joined Bruce about three years earlier. Hampton originally hired Oteil as a drummer. "We played about three gigs and then he picked up the bass one day and I said, 'That's what you'll be playing from now on," Hampton says with a laugh. "He was a good drummer, but he was like the greatest bassist I had ever heard."
All the musicians came to Hampton as virtuosos. He opened up their boundaries. More accurately, he obliterated the very concept of boundaries.
"Old-timers would tell me that Oteil was playing too much, but the song was always there," says Hampton. "He never lost that. And he was 21 and full of this amazing energy, so why not let him be free? Then, I told him, whatever he wanted to do, do the opposite."
But isn't that a contradictory concept—be free and do the opposite of what you want to do? "Yes!" says Hampton. "That's it."
If that contradiction makes perfect sense to you, then you are well on your way to understanding Hampton's Zambi musical approach, which Burbridge sums up in a few words: "Bruce was our 'professor of out.'"
The Colonel's educational role was obvious, but to this day he cringes at being called a mentor, even after 20 more years discovering great young players.
"I learn as much from them as they do from me," he says. "What made me unusual was that everyone my age had either quit or made it. No one was playing clubs and putting together new bands on the cheap like that."
I believe it was 2/7/92, The Post Office in Augusta, GA. The Dixie Dregs opened up for Widespread Panic, probably because of T Lavitz' short-term stint with WSP. John Bell took the stage after the opener and said "thanks to the Dixie Dregs for opening up for us. They are a young band with a lot of promise."
Ha! Still have the master cassettes…...
great article—
here's ARU at a little club in Birmingham, AL called The Nick in 1991.
especially check out the last tune.
Finally, a band less interesting than the Velvet Underground.
Fuck off, Pookums. ARU FOREVER!!!
ARU is the truth. Music unbound.
Eat a dick pookums
If you enjoyed this article, check out the Hampton documentary "Basically Frightened" - $2.99 rental from Amazon… although it's worth buying. Really well done. http://www.amazon.com/Basically-Frightened-Musical-Madness-Colonel/dp/B00CJ1WHHW/ref=sr_1_3?ie=UTF8&qid=1399737925&sr=8-3&keywords=col+bruce+hampton
After discovering them way too late, I would tell people they're the best "bar band" of all-time.
Saw them at least 40 times. Shit was amazing and I'm definitely lucky to have "been there"~~~Otis
The ARU live album on Capricorn records is one (in my opinion) of the greatest live albums of all time.
Great article. I believe the unnamed band member in the photo is percussionist Count M'Butu.
ARU achieved a level of musicianship with a reckless cohesiveness, musicality and humor that was on a level at or even beyond Zappa…
I discovered them at the 2004 New Orleans Jazz Fest. I was having a beer at the Ugly Dog before heading back to my hotel and the very inebriated and horny couple next to me offered me a ticket to the Howlin' Wolf to see them. I stood there like a fool,with my mouth wide open for a full 2 hrs. and have been a LOYAL follower ever since
I saw them as much as I could in '92-93 with the original band and they were always killing. Much like Phish was at the time. The reunion shows they did a few years back were great too but Matt Mundy will be missed. Having said that, if I had a choice now between seeing Phish or a reunited ARU it would ALWAYS be ARU.
So, so lucky to have these guy's in my back yard. Been blown away by them many times. Most recently took my wife to her first ARU show at the Georgia Theater a couple of years ago and she proclaimed that that was maybe the best musical performance she had ever seen (out of hundreds of shows!) Afterwards she spent about 15 minutes chatting with Jimmy who is just as nice and gracious as he has always been. Much love and respect for all these fine men.
I saw them a handful of times in Macon, Georgia. At the Fairgrounds and a converted trolly barn. Great nights of music. Fantastic band. Matt Mundy was a unique musical voice. What a band!
Pookums is an ass napkin.
Matt Mundy is the JD Salinger of the jam world. Won't you come out & play?
Wish we could see them again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Sadly I never saw them, but I can attest to how great a guy Jimmy is. I saw him with Frogwings one night when I was a drunk idiot college kid, and for some reason he let me shake his hand at the end of the show and talk for about 5 minutes.
Sent this article to my Deadhead uncle, (aptly named Uncle John)... At the recent New Orleans JazzFest he told me he used to play golf with Col Bruce in the Atlanta area and was pleased to see he was still out on the road gigging.

Dragon Warrior III (NES) review
"Dragon Warrior III is easily one of the greatest triumphs on the Nintendo Entertainment System, a gem that sparkles even in an age where all the other games on the block have larger assets. Not so much a game as an experience, this is one RPG that you owe it to yourself if the term 'role-playing' excites you even a little."

EVALUATION IN ACTION! Credible Qualitative Design & AnalysisApril 18, 2013 at 3:00 PM EDT, 2:00 PM CDT, 1:00 PM MDT, 12:00 PM PDT
(90 minutes)
Anecdotes and qualitative evidence are critical to communicating the transformative effects of arts and culture and giving a full sense of impact of arts for change work. Learn how to collect and analyze qualitative data that's credible. Qualitative information is important for indicating changes in awareness, attitudes, the content and tenor of public dialogue, and in describing the role, nature, and efficacy of aesthetic activity. But it is often considered "soft" evidence. Through multiple evaluation stories by arts practitioners that touch on ethnographic and other qualitative approaches, this webinar illuminates principles to support systematic planning for, and collection and analysis of qualitative data so that findings hold water. You'll learn how to select and prepare credible evaluators and/or observers, methods to summarize and analyze qualitative data such as interview and focus group documentation, dialogue and meeting notes, and dialogues; and how to combine qualitative and quantitative information to communicate concise and compelling results.

Branston excited by reunion with Sheridan at Argyle
Posted: January 11, 2013|
DEFENDER Guy Branston is excited about being reunited with new Plymouth Argyle manager John Sheridan at Home Park.
Branston today signed a contract with the Pilgrims until the end of the season.
The no-nonsense 34-year-old centre-back has gone straight into the squad for the League Two game against Morecambe at Home Park tomorrow (3pm).
He has previously played for Sheridan at Oldham Athletic so knows what to expect from him.
Branston told Herald Sport: "He doesn't suffer fools and I'm not a fool. He wants somebody to come in here and be vocal and be a defender.
"You get that with me. I'm not going to bring the ball down on my chest and cause a problem for the defence.
"I'm going to clear it and get up the pitch. Hopefully, if we can keep clean sheets we will score goals because we have got some talented young lads here."
Branston signed for Aldershot Town in the summer but he had his contract with them terminated by mutual consent on January 3.
He made only five appearances for the Shots, with one of them coming against Argyle.
That was in a Johnstone's Paint Trophy tie at Home Park on October 9, when the Pilgrims came out on top 2-1.
Branston was injured, but at the game, when Argyle lost 2-0 to Aldershot in their League two season-opener in August.
He has also seen DVDs of the Pilgrims in action over the festive period, when they drew 1-1 at home to Torquay United and lost 2-1 at Bristol Rovers.
Branston said: "I know my football and I know who's a good player and who's a bad player.
"There are definitely some good players here. I have got a lot of time for (Durrell) Berry and (Curtis) Nelson as defenders.
"I'm a big fan of (Joe) Lennox, and (Luke) Young is getting a good resume for what he has done.
"We have just signed a really top striker in Ronan (Murray). I played with him when he was on loan at Torquay.
"The gaffer (Sheridan) knows I like working hard with the young lads and trying to improve them because I want to step into that later in my career."

Obama Takes Oath -- Again
Professor Jenny Martinez is interviewed for a segment on ABC-7 News regarding President Obama's first executive orders, including one to close the detention facility at Guantanamo within one year:
It was with the stroke of the pen that implemented immediate change on the president's first full day in office as Obama signed executive orders. He imposed new rules on government transparency, putting a pay freeze on senior staffers and mandating new limits on lobbyists.
And on Thursday, the president will continue to set the tone. He will sign an executive order that will shut down the Guantanamo Bay prison within one year. Stanford law professor Jenny Martinez filed briefs for some of the detainees. "It sends a clear message to the rest of the world that the U.S. is going to be a leader in human rights again, we're going to be the country that everyone admires and respects," said Martinez.
