This is a continuation-in-part of application Ser. No. 08/344,077 filed on Nov. 23, 1994, U.S. Pat. No. 5,568,405.
A. Field of the Invention
The present invention relates to agriculture, and in particular, to determining plant population and spacing for row crops.
B. Problems in the Art
Maximum yields from row crops can be related to maximizing uniform distribution of the plants. Therefore, it is of interest to find out plant distribution for planted fields.
Row-crop planters generally are able to crudely control plant spacing. After-the-fact plant spacing measurement can provide information regarding faulty or mis-calibrated planters. It can also provide information regarding problems caused by particular soil conditions or pests.
The only widely used post-emergence plant spacing measurement system is manual in nature. A ruler or tape measure (or other measuring standard) is manually placed between succeeding plants in a row. Besides the obvious burdensome nature of this procedure to gain enough information to get an accurate picture of plant spacing and plant population, inaccuracy problems exist. Also, it requires essentially pen and paper calculations to derive estimates of plant population and spacing variability. Still further, it cannot provide immediate information. Additionally, storage and retrieval of the final calculations are difficult.
There is a real need in the art, therefore, for a way to improve over the present method of measuring plant spacing and calculating plant population.
It is therefore a principle object of the present invention to provide an apparatus and method which improves over and resolves the problems and deficiencies in the art.
Other objects of the present invention are:
1. An automated system of plant spacing measurement and plant population determination.
2. An automated way to calculate and record plant spacing, plant population, and plant spacing variability.
3. An almost real-time ability to calculate and record the above data.
4. Improved accuracy in recording the data and making the determinations.
5. An easy to use, economical apparatus and method.
6. The ability to store and recall the data.
7. An automated system of plant spacing measurement and plant population determination which is integrated with a combine head so that each harvested row of row planted crops is monitored.
It will be appreciated that additional objects, features, and advantages of the invention will become more apparent with reference to the specification and claims.
The present invention includes an automated apparatus and method for making determinations of plant population and spacing for row crops. Plants along the row are sensed and an electrical signal is generated for each sensed plant. Concurrently the distance between plants is sensed and recorded. The accumulated data over a given distance allows calculation of plant population, spacing, and spacing variability for a given area of the field.
The invention features, in one embodiment, improved accuracy and plant sensing. An adjustable mechanical arm senses a plant as the apparatus of the invention passes by the plant. The arm activates a device which then produces an electrical signal indicating the sensed plant.
Another feature of the invention according to an embodiment of the invention involves more accurate determination of distance between plants. A ground-contacting tire rotates. A device produces an electrical signal correlated to precise distance along the ground traveled by the tire. The signal correlated to distance can then be correlated to the signal of the sensed plants.
According to another feature of an embodiment of the invention, more accurate calculations of plant population and spacing are derived. The accurate information regarding plant spacing is utilized to calculate the standard deviation of spacing between plants which then more accurately portrays plant population for a given area of the field.
By utilizing a processor, the information can be generated in close to real time.
In another embodiment of the present invention, a number of sensors are attached to a combine head so that the plant population can be monitored in each row as a combine harvests a field of row crops.

A. Overview
The following description will set forth in detail a preferred embodiment of the present invention. Frequent reference will be taken to the appended drawings, which form a part of this description. Reference numerals will be used to indicate certain parts and locations in the drawings. The same reference numerals will indicate the same parts and locations in the drawings unless otherwise indicated.
B. Hardware
FIG. 1 depicts, in isolated perspective format, a plant spacing measurement device 10 according to the present invention. Device 10 is particularly adapted for use with small or smaller sized plants, such as young corn, as one example. A crop-row (indicated generally by the line 12) includes a plurality of plants 14 (indicated by succeeding reference numerals 14A, 14B, 14C, etc.).
It is understood that device 10 is generally passed through a field once the plants are of a sufficient size that they are distinguishable mechanically from grasses and small weeds. For example, approximately one month of growth for many row-crop plants is sufficient.
FIG. 1 illustrates the major components of device 10. A base or frame 16 serves as the main supporting component of device 10 and contains certain electrical components which will be described in more detail later. It also contains certain mechanical components which will also be described later.
A member 11 extends from base 16 and can either comprise a handle for manual gripping and control of the movement of device 10 through the field, or can comprise a mounting bracket for attachment of device 10 to another piece of equipment or a vehicle, such as a tractor or field implement like a cultivator or a combine (described below).
A ground-contacting tire 18 is rotatably connected to frame 16. In the preferred embodiment, the height of frame 16 could be adjustable to accommodate the use of the invention on different size plants. For example, when sensing small plants, the arm 32 would need to be close to the ground. When sensing larger plants, the arm 32 could be farther from the ground.
What will be called shields 20 and 22 are connected to frame 16. Shield 20 is directly connected to frame 16; shield 22 is connected to frame 16 by U-shaped brackets 24 and 26. As can be seen in FIG. 1, U-shaped brackets 24 and 26 extend upwardly from base 16 in an inverted fashion and then back down to suspend shield 22 in a spaced apart position from shield 20 to allow plants 14 to pass between the shields 20 and 22.
Shields 20 and 22 can be solid and made of such materials as plastics, metal, or similar fairly rigid materials, or can be non-solid, such as mesh, screen, or even a more open framework. Shields 20 and 22 pass above the surface of the ground when in use.
It should also be noted in FIG. 1 that the space between shields 20 and 22 defines what will be referred to as a plant channel "C". The forward or receiving portion of the plant channel C is defined by corresponding front ends of shields 20 and 22, and as shown in the Figures, those front ends are usually wider apart than the distance between shields 20 and 22 at the exiting or rear ends of shields 20,22. Shields 20 and 22 therefore basically allow for some variance of alignment of plants 14 along row line 12 so that plants are not missed or so that they are gently directed into channel C to avoid damage and also in a fashion that they are funneled towards the constricted exiting end of shields 20 and 22 which facilitates more accurate plant sensing.
FIG. 1 also shows that at an opposite end of member 11 is a handle grip 80 which is used to control movement of device 10 along the crop row. A control box 82 is mounted on the end of member 11 and/or handle grip 80. Control box 82 houses most of the electronics with respect to device 10 and the battery power source for device 10. Wires 87 communicate electrically between base 16 and control box 82.
Control box 82 has a display 81 (for example, an LCD), a control switch 83 and a recharging light 84. Another control switch 85 exists on handle grip 80. These components are standard, off-the-shelf products.
It is to be understood that the parts described above regarding device 10 can be made from a variety of different materials. They can also be configured of various shapes and sizes. Those matters can be selected according to design choice.
FIG. 2 shows in perspective an alternative embodiment 100 according to the present invention. Device 100 is preferably for larger sized row crop plants. A larger wheel 102 is rotatably connected to a base 104. Handle 106 extends away from base 104. It is to be understood that handle 106 can be connected to a hand grip and control box like described with regard to device 10, or otherwise could be connected to some other structure such as, for example, a tractor or implement.
Device 100 differs from device 10 principally in that a narrow rail 108 having an outwardly bent front end is connected to base 104. Arm 110 extends outwardly below rail 108 and is pivotable towards rail 108.
Whereas device 10 has shields 20 and 22 through which plants 14 are guided and detected, on larger plants it is not reasonable to have an outside shield analogous to shield 22 because it would require a structure to extend upwardly, over, across the crop row and then back down to such a shield. This would be unwieldy and unbalancing. Furthermore, with larger plants, it has been found that the operator can adequately steer tire 102 such that the plants slide along rail 108 and then trip or depress arm 110 to allow plant sensing.
FIGS. 2-7 show in more detail the precise arrangement and relationship of certain parts of devices 10 and 100. As shown in FIG. 3, tire 18 of device 10 is rotatably mounted to frame 16 along a rotational axis 28. The precise manner of rotational attachment to frame 16 is within the skill of those skilled in the art. For example, an axle can be used, or frame 16 itself could serve as the rotational support or hub. In the preferred embodiment, tire 18 is fixedly attached to a hub 29 that is rotatably journaled in base 16. In the preferred embodiment, a toothed wheel 30 is concentrically and rotatably mounted to hub 29 inside frame 16. Essentially wheel 30 rotates with tire 18.
FIG. 3 shows in more detail how shields 20 and 22 are flared outwardly to receive and funnel plant 14 through plant channel C. FIG. 3 also shows that an arm 32, pivotably attached to frame 16, includes an outer free end. A plant 14 passing through the plant channel C between shields 20 and 22, if of sufficient thickness (greater than the distance designated as B), will strike arm 32 and cause arm 32 to pivot away from plant channel C. Once plant 14 has passed arm 32, arm 32 (which is spring loaded or otherwise biased), returns to its normal or original position awaiting the next plant.
A more specific example of the attachment of a wheel to the base is set forth in FIG. 4. FIG. 4 shows in cross-section the relationship between tire 106 and toothed wheel 112 for device 100. An axle 126 of various cross-sectional diameters, extends through the center of wheel 106 (and is connected to wheel 106 by bolt 116 and washer 118). The other end of axle 126 is connected to tooth wheel 112 by bolt 120 and washer 122. A bearing 124 surrounds the portion of axle 126 between tire 106 and toothed wheel 112 and is held in place by a spline 128. This allows smooth and reliable rotation of wheel 106 relative to base 104.
In both embodiments 10 and 100, two signals are derived from the portion of the devices that are near the ground. These signals are used to calculate the data regarding plant distribution. First, the distance traveled is calculated. By referring to FIG. 4, it is to be understood that a toothed wheel 112 rotates between the sides of an optointerrupter 114. Predesign of the diameter of wheel 112 and the spacing between teeth around the perimeter of wheel 112 allows optointerrupter 114 to provide a signal to control box 82 (FIG. 1) from which distance traveled can be derived.
FIG. 5 illustrates one way sensing of the plant can be accomplished. Arm 110, consisting of a relatively thick and rigid wire, is bent so that it has a portion that extends at an oblique angle from rail 108 (See FIG. 2). The portion of arm 110 within base 104 has bearings 130 and 132 which allow it to rotate in housing 104. A secondary arm 134, in a preferred embodiment made of wire, is wrapped around arm 110 and fastened in place. Its outer flattened end 136 normally is positioned between the sides of optointerrupter 138.
A torsion spring 140, inserted along arm 110 and having first end 142 placed along arm 110, and a second end 144 which abuts against a portion of the interior of the base 104, holds flat end 136 in its normal position in between sides of optointerrupter 138, and holds the outer free end of arm 110 in a spaced apart oblique position from rail 108. End 142 of spring 140 is basically fixed relative to arm 110. Movement of arm 140 by a plant causes spring 140 to deflect so that when the plant is passed, spring 142 seeks its original, undeflected state, thus turning arm 110 back to its normal position. When a plant hits arm 110 it pivots it towards rail 108, secondary arm 134 pivots out of optointerrupter 138 (e.g., dashed lines of arm 42 in FIG. 6). In the preferred embodiment, the torsion spring 140 is configured so that it snaps the free end of arm 110 immediately back to the normal position (shown in solid lines) once the plant is passed. At this point the flattened portion 136 of secondary arm 134 re-blocks optointerruptor 138. The reblocking of optointerrupter 138 is the point in time of determining a sensed plant.
It is to be understood that by selection or adjustment of the torsional characteristics of spring 140, the sensing sensitivity of arm 110 can be adjusted. A stiffer spring 140 would be used for larger row crop plants and therefore would reduce the likelihood that smaller plants such as grasses or weeds would trip arm 110.
It is also to be understood that a wide variety of different arrangements as to the structure of a triggering mechanism and how it would actuate a signal indicating the sensing of the plant is possible. Different distance measuring apparatus and methods are also possible. For example, a distance measurement could come from a field implement such as a combine. Such a measurement could come from conventional means or from a GPS receiver or a radar motion sensor. Alternative triggering mechanisms could include optical sensors, infrared sensors, microwave sensors, etc.
FIGS. 6 and 7 illustrate how plants are sensed and an electrical signal for responding to the sensing of the plants is generated with regard to device 10, and also how distance between plants is measured and a signal corresponding to that distance is generated with regard to device 10.
FIG. 7 shows an inside elevation of a toothed wheel 30. Each tooth 38 is uniformly sized and spaced relative to a succeeding tooth 38. An optointerruptor 40, consisting of a photo emitter and a photo detector, is positioned so that the path of rotation of teeth 38 passes between the photo emitting and photo detecting portions of optointerruptor 40 (see FIG. 6).
With respect to arm 32, it can be seen in FIG. 6 that it pivots about pivot 41. A secondary arm 42 pivots with arm 32. Secondary arm 42 includes a portion 46 (see FIG. 7) that extends between the photo emitting and photo detecting portions of a second optointerruptor 43. When arm 32 pivots out of plant channel C, portion 46 passes from its original or normal position between portions of optointerruptor 42, to a position that opens the light pathway between those portions. A spring or other biasing means can be associated with pivot 41 or arm 32 to return arm 32 to normal position once force against arm 32 is released.
Another feature is shown in FIG. 6 is the ability of shield 22 to be pivoted from the position shown in solid lines, to a position shown in dashed lines. This allows the width of the restricted exit end of plant channel C to be adjusted for different sized plants. This is important for the following reason. If the plants being measured have an average thickness of, for example, 1/2" across their stem, by making plant channel C approximately 1/2" thick, it will insure that arm 32 is moved when such a stem, or a stem of substantially similar size passes. However, if weeds or grasses pass through (with thicknesses substantially less than 1/2'), they can pass by arm 32 without tripping it.
Shields 22 could be attached to bracket 24 by means well known by one of ordinary skill in the art. Alternatively, shield 22 could be fixed to bracket 24, but a separate pivotable piece, such as a wire or a panel could be pivotably attached to shield 22, bracket 24, or bracket 26, and have a rearward end that could be moved relative to the free end of arm 32 to provide a larger or smaller gap for plants to pass through.
C. Electrical Components
FIG. 8 is an electrical schematic of a preferred embodiment of the electrical circuitry according to the invention.
FIG. 8 shows that in the preferred embodiment a five volt power source is utilized. In the preferred embodiment electrical power for the circuitry is provided by four Ni-Cad batteries 149 which can be recharged from any AC or DC source from 8 to 24 volts. Reference numeral 150 in FIG. 8 shows a recharger circuit used in the preferred embodiment. A port or electrical connection can be placed on device 10 or 100 to receive standard electrical household current into recharger 150, which then converts it to a form that is useful in recharging the Ni-Cad batteries. The four Ni-Cad batteries provide numerous hours of operation per charge. Recharging could be from a 12 volt automotive system or by other means such as are well known. Four 120 ohm resistors 152 are used for charge current limiting, and will allow charge voltage to be considerably higher than 12-14 volts, if necessary. A bridge rectifier 154 is used so that charge polarity is unimportant. An LED 84 (see also FIG. 1) indicates when charger voltage is present. A processor 50 receives input signals from optointerruptors 40 and 42 at pins 12 and 13 respectively (see "Wheel" and "Plant"). Processor 50, utilizing the five volt power source, operates a display 52. A memory 54 and latch 56 allow storage of data collected by device 10 for selective display.
Since the address and data buses used with the circuitry are common, 74HC573 octal transparent latch 56 is needed to store RAM 54 address information during RAM read/write operations.
Processor 50 is an 87C51FB microprocessor. Its main advantage is its low power requirement. Its functions are to perform calculations based on the signals generated by the two optointerruptors 40 and 42, store and retrieve RAM 54 data, and drive display 52. Microprocessor 50 runs at 12 MHz.
Display 52 is a 16 character×2 line transflective dot matrix LCD as from Optrex. It has its own element drivers, character generators, and RAM, so the microprocessor 50 only tells LCD 52 what to display and where.
The 74HC00 quad NAND gate (see three NAND gates encircled by dashed line 70 between elements 50 and 52 in FIG. 8) provides an interface between microprocessor 50 and display 52. A 25K potentiometer 72 from the negative voltage circuit to ground provides adjustable display contrast for varying light and reading angles.
Optointerruptors 40 and 42 a re matched pairs of infrared emitters and detectors, with a small air gap between to allow passage of a moveable interrupting device (in the preferred embodiment, portion 44 (or 136) or wheel 30 (or 112)). As beam intensity decreases, the infrared detector (a photo transistor ) turns off, increasing the collector voltage (sensing when arm 32 (or 110) returns to normal position). The dark output voltage is very nearly 5 volts, and with no light interruption, nearly 0.
The 47K resistors and 0.047 micro-fared capacitors on four inputs of a 74HC14 Schmitt trigger inverter 156 form low pass filters to reduce noise susceptibility. Since the motion of wheel 30 (or 112) and portion 44 (or 136) is relatively slow, the photo transistor outputs of optointerruptors 40 and 42 also change rather slowly. Schmitt trigger 156 provides squared output even with a slowly changing input, and its built-in hysteresis reduces false triggering. Stated another way, as an optointerrupter is occluded, or occlusion is removed, its electrical output increases or decreases somewhat linearly in the form of a voltage. The Schmitt trigger provides a sharp precise cut-off in either instance thus eliminating any false plant sensing caused by noise.
Information can be displayed on display 52 (in the preferred embodiment a dot matrix LCD) which is driven by processor 50. In the preferred embodiment, an audio annunciator 58 (in this case a horn) can provide an audible signal each time a plant 14 is sensed and/or when a control switch, described below, is actuated.
A few control switches are used to invoke the various operating modes. Control switches can be used to select between various display modes for devices 10 or 100. Signals from the control switches are debounced and squared by the Schmitt trigger 74HC14 (reference numeral 156).
Control switch 83 (see also FIG. 1) and control switch 85 (see also FIG. 1) can control functions such as the following. The "next" switch (reference numeral 158 in FIG. 8), serially cycles through a number of measurements and displays them on display 52. The "mode" switch (reference 160 in FIG. 8) allows selection between modes such as recall or not recall.
Reference numeral 162 in FIG. 8 shows an on/off switch for the device. It is to be noted that processor 50 can be programmed so that the on/off switch merely controls whether display 52 is on or not so that all stored measurements are saved for later use, which takes very low power, as compared to operating the display continuously.
The timer or counter in microprocessor 50 which performs the distance interpolation function also generates a 4 kHz square wave signal which is fed to inverter 74. The output of inverter 74 drives a voltage converter circuit 166 which provides a negative voltage for an LCD contrast adjustment. Inverter 76 provides current drive for the audio annunciator.
All electronic parts are generally available, commodity type components. As many surface mount parts (resistors, capacitors, IC's) as possible were used for compactness. The IC's are all CMOS because of their availability and low power consumption. Materials such as for the housings can be from a wide variety of choices. Examples are wood for ease of fabrication and convenience, however, such things as rigid plastic or metal would be preferable because of stiffness and strength. For embodiments used with field implements such as he combine shown in FIG. 11, the housing or housing support may optionally be comprised of a part of the implement, for example the row dividers. Member 11 extending between the wheel portion and the handle portion is preferably aluminum or steel tubing.
D. Software
The addendum to this specification contains an actual software program according to the preferred embodiment of the present invention. Such programming is loaded into processor 50 by means well known to those skilled in the art. FIG. 9 summarizes, in flow chart form, the program of the addendum.
FIG. 9A indicates the basic overall structure of the software, comprising standby mode 102, sleep mode 104, spacing mode 106, and recall mode 108. Standby mode simply places the processor in a waiting condition until it is instructed to begin measurements (spacing mode 106). Sleep mode allows conservation of battery resources without losing information stored in memory. Recall mode allows different measurements to be recalled and viewed.
FIG. 9B illustrates one sub-routine of the software (see reference numerals 202-214). Further sub-routines which initialize registers 204, update display label fields 208, update display data fields 212 are shown in flow chart form at FIGS. 9C (see reference numerals 302-308), 9D (see reference numerals 402-422), and 9E (see reference numerals 502-514) respectively.
FIGS. 9F (see reference numerals 602-640) and 9G (see reference numerals 702-712) show the sub-routines for spacing mode 106, namely how wheel tooth detection occurs and how plant detection occurs; and how they then both function to provide information relevant to the measurements that can be accomplished by the invention.
It is to be understood that the embodiment of the software programming set forth in the appendix is based upon flow chart of FIGS. 9A-9G but that other flow charts and other software programming code could be used to accomplish the goals of the invention.
FIG. 11 shows an alternative embodiment of the present invention. FIG. 11 shows a combine 220 having a corn head 222 used for harvesting a number of rows of corn. The corn head 222 includes a number of row dividers 224 which are used to channel the rows of corn plants into the combine 220. Between the row dividers 224 are sensors 226 which are each similar to the sensors shown in FIGS. 1 and 2 and described above. As the combine 220 is harvesting corn, the sensors 226 will sense the corn plants in each row that is harvested. In this way, the sensors 226 can monitor the population and spacing of each row of corn plants much like the device shown in FIGS. 1-7. The sensors 226 can be mounted before or after the gathering chains for non/disturbance or assistance.
FIG. 12 is an electrical schematic diagram of one of the sensors 226. The sensors 226 could be identical to those shown in FIGS. 1-7, but preferably use potentiometers or optical sensors to give more complete information about the motion of the sensing arm of the sensors 226. In one embodiment, each sensor 226 uses a quadriture output optical encoder 242. One suitable quadriture output optical encoder is manufactured by Oak Grigsby with a part number 94Q128-00-00. The outputs of the optical encoder 242 allow tracking of the speed and direction of the sensor arm 110. As a result, the secondary arm 134 and optointerrupter 138 (FIG. 5) can be eliminated by this embodiment. In addition, there is no need for the sensor arm 110 to make a full return in order to determine the presence of a plant. The outputs of the optical encoder 242 also make it easy for a microcontroller 244 to keep track of the actual sensor arm position if desired. One suitable microcontroller is manufactured by Microchip with the part number PIC16C54A. As shown in FIG. 12, the microcontroller 244 is connected to communication lines via connections J3 (communications in) and J4 (communications out). Both the microcontroller 244 and the optical encoder 242 are connected to a voltage regulator U1 for providing the appropriate operating voltage. Since a combine moving quickly through a corn field may see as many as thirty plants per second in each row, it would be difficult to read the two output channels of the optical encoder of as many as twelve sensors (for a twelve row combine, for example). Therefore, the preferred embodiment includes a small controller in the housing of each sensor 226. The controller in each sensor 226 reads sensitivity information from a central controller, reads signals from the optical encoder, and communicates to the central controller when each plant is detected according to that sensitivity information.
By sensing plants in each row that is harvested by the combine 220, various benefits are found. First, the activity of corn head 222 of the combine 220 is actually monitored, much like a planter, so that if a row becomes plugged, the sensor 226 in that row will quit sending plant signals to the central computer which can activate an alarm alerting the combine operator that a row is plugged. In prior art combines, operators must watch all rows of the corn heads to verify proper operation since inoperative gathering mechanisms of the corn head 222 are not always immediately noticed by the combine operator. Another useful benefit of sensing each row of plants is the ability to let other devices such as yield monitors, area counters, head height controllers, etc., get an immediate signal as to when the combine is actually taking in plants.
FIG. 12 is a block diagram of the embodiment of the present invention shown in FIG. 11. FIG. 12 shows a sensor 226, which includes a microcontroller, for each row of the combine head 222. Each of the microcontrollers within each sensor 226 communicate with a central controller 228 which in one embodiment is comprised of a lap top computer which could be implemented conveniently and relatively quickly. The central controller 228 receives information from each sensor 226 and computes a mean population and standard deviation of spaces in each row, using the combine's speed sensor 230 to determine the distance between plants. This computed data is electronically sent to a data logging device, or yield monitor 232 which may record the combine's location within the field, crop yield, and grain moisture content via other types of sensors. The central controller 228 communicates with the yield monitor 232 via a communications link 234 which may be comprised of an RS232, RS485, CAN, etc., communications line.
Some embodiments of the invention may use one of several types of electronic position encoders to more completely convey to the microcontroller 244 the motions of sensing arm 32. The preferred incremental optical encoder 242 is similar to the previously described optointerrupter, but provides two square waves (preferably 128 pulses per revolution), 90 degrees out of phase. By reading the two signals, the microcontroller 244 can easily determine the mechanical direction and displacement of the encoder 242.
The microcontroller 244 in each sensor 226 is programmed to continually read output channel A of the optical encoder 242. Each time the output voltage of that channel changes from low to high or high to low, channel B is read. If A has transitioned high and B is observed to be low, it is known that the encoder 242 is turning clockwise, but if B is high, the rotation is counterclockwise. Conversely, when A transitions low and B is observed as low, direction is counterclockwise, or clockwise if B is observed high.
The encoder 242 is mechanically driven by the sensing arm 32, and thus rotated clockwise by plants as they enter the corn head 222, and counterclockwise by the arm return spring when the arm 32 disengages each plant. The microcontroller 244 must see the arm being rotated counterclockwise by an entering plant. When the arm looses contact with the plant and begins clockwise rotation, the microcontroller 244 counts the number of voltage transitions of channel A. When a predetermined quantity (adjustable via the central controller 228) of uninterrupted transitions is reached, one plant is registered and the information is conveyed to the central controller 228. Another plant cannot be registered until the microcontroller 244 recognizes that the arm is rotated counterclockwise at least slightly by the next plant.
The individual row units communicate to the central controller 244 in conventional ways well understood by those skilled in the art. One example of the communication means is that each row unit is wired to its own dedicated input to the central controller 228, and a simple voltage pulse from the row unit attributes a plant to the correct row. Another means is to have all row units on a common reporting bus. Each row unit must then also identify to which row the detected plant belongs.
If the user of the combine 220 utilizes precision farming equipment such as a GPS receiver 236 and an electronic data logger 238, the user may electronically log the acres covered by the combine 220. In the prior art, an area accumulator may be switched manually to represent a selected swath width and start/stop times. By knowing exactly when the crop is entering each row of the combine head 222 by direct plant sensing, the accuracy of these measurements (swath width, start/stop times) is increased. With the present invention, the area accumulator would turn on when population numbers from the central controller 228 show a crop presence, and turn off if no crop is entering.
Another benefit of the embodiment of the present invention shown in FIG. 11 is found in fields which are not flat or rectangular. If a combine approaches rows from other than a right angle, the rows begin or terminate progressively across the combine. For a combine with an eight or twelve row head, significant portions of the harvesting can show less than a full compliment of rows at the corn head. This situation causes significant errors in area accumulation, whether switched manually or automatically. The situation also gives incorrect yield data since the yield monitor does not know that only a portion of the corn head is gathering crop. By using a sensor 226 at each row of the combine 220, the yield monitor can determine the present effective width of the corn head 222 and base the area and yield data on the correct number of rows for that moment. So, as the combine 220 enters point rows, the yield monitor 232 could see that corn is entering first on one row so that the area and yield are based on the width of one row. As soon as the head 222 sees two rows, the area and yield are then based on two rows, etc. The yield monitor should recognize that this situation of progressively more and progressively fewer rows almost surely progresses from one end of the head toward the other end. Missing rows in the middle of the head are almost undoubtedly caused by something else, such as, plugging or a missing row.
When a combine such as combine 220 begins harvesting a field, there is a time lag before the grain makes its way through the combine head 222 to the location of the moisture and yield sensor. This time lag may be more than 25-30 seconds, for a combine traveling at 5 miles per hour, this is a shift in position of perhaps 200 feet. By incorporating the population data from the central controller 228, the yield monitor 232 can self-calibrate the delay. To calibrate the delay, the yield monitor 232 simply measures the time between the entry of the corn into the head and the entry of grain into the other sensors. This delay can change according to the type of combine, the speed of the combine, the crop yield, gain moisture, land grade, type of crop, and various other harvest conditions, therefore this self-calibration is advantageous. The present invention can also determine the shape of a gap in a field which gives an indication of the cause of the gap. For example, a round gap may result from deer or other pests. A square gap may result from cultivation or planting errors.
As mentioned before, the central controller 228 is capable of notifying the operator when plants are not being detected by one or more of the row sensors 226. When plants are not being sensed by a row, the central controller 228 can notify the operator via a display 240 of a plugged head, missing plants and row, incorrect position of the combine in a field, etc., so the operator can take the appropriate action.
E. Operation
Device 10 measures plant population and spacing variability by sensing the distance between successive plants in a row and performing calculations on the accumulated measurements. When a plant 14 of sufficient girth (wider than distance B in FIG. 3, or strong enough to overcome the torsion spring or outward biasing of the arm 32 or 110) is passed between arm 32 or 110 and shield 22 or 108, arm 32 or 110 pivots so that portion 46 or 136 of secondary arm 44 or 134 temporarily moves out of the light beam path of optointerruptor 42 or 138. A signal (such as an electrical pulse) is then sent to processor 50. It is to be noted that this method was used rather than directly sensing a plant 14 with a light beam because it is less sensitive to contamination, more durable, and easier to adjust for proper plant size and so it will not sense non-relevant things such as grass and weeds.
Arm 32 (or 110) is spring loaded and once plant 14 passes arm 32 (or 110), arm 32 (or 110) returns quickly to its original position and the light path is again interrupted to produce a signal to processor 50 correlated to the sensing of a plant. The torsion spring previously described can be used because it is fairly easy to adjust by adding or subtracting turns of the spring along the arm. Other types of biasing are possible. Ultimately it would be preferable to be able to adjust the tension of the arm from some control exterior of the housing or base. In the preferred embodiment, the "sensing" of the plant occurs once arm 32 (or 110) snaps back into normal (undeflected) position. Then the analog output of optointerruptor 42 (or 138) is squared by the 74HC14 Schmitt trigger 156. The signal therefore is a much better and well defined plant sensing signal.
Concurrently, distance is measured utilizing rotating ground-contacting tire 18 (or 102) which directly drives toothed wheel or vane 30 (or 112). As tire 18 (or 102) rotates teeth 38 of vane 30 (or 112) alternatively interrupt and pass the light beam of optointerruptor 40 (or 114). The circumference of tire 18 (or 102) divided by the number of teeth 38 in toothed wheel 30 (or 112) yields the distance traversed by device 10 (or 100) per tooth 38. In one preferred embodiment a 150 mm diameter tire 18 (or 102) is used along with a thirty tooth toothed wheel or vane 30 (or 112). This results in approximately 15.7 mm of travel per pulse generated by optointerruptor 40 (or 114). As previously described, however, larger tires can be used if desired (for example, for use in fields having larger plants or in fields having more disruptions such as uneven terrain, clods of dirt, crop trash, and larger weeds). The size of the wheel must be known as well as the number of teeth on the toothed wheel.
In the preferred embodiment, improved accuracy and finer distance resolution is achieved by utilizing an interpolation calculation in microprocessor 50 based on the input signals from optointerruptors 40 (or 114) and 42 (or 138). A counter within microprocessor 50 sums the number of timing pulses between successive distance pulses. The distance between two successive plant signals will be equal to a certain number of wheel signals plus two fractions of a wheel pulse. To interpolate these fractions, the processor divides the number of timing pulses from the beginning of the current wheel signal to the last plant signal by the total number of timing pulses over the entire previous wheel signal. This way, without knowing the number of timing pulses in the current wheel signal, the processor can accurately estimate at what portion of the current wheel signal a plant was sensed.
For example, assume a first plant was sensed at the beginning of a first wheel signal and a second plant was sensed during the second wheel signal. Since each wheel signal corresponds to 15.7 mm, without interpolation, we only know that the distance between plants one and two is between 15.7 mm and 31.4 mm. Now assume that the processor counts 20 timing pulses during the first wheel signal and counts 15 timing pulses from the beginning of the second wheel pulse and when the second plant was sensed. The processor divides 15 by 20 to estimate that a plant was sensed 3/4 into the second wheel signal. Therefore, the distance between plants one and two would be: 15.7+(3/4) (15.7)=27.5 mm. Note that when interpolating the distance between the second and third plant, the processor will go through the same process and will also add (1/4)(15.7)mm to account for the remainder of the second wheel signal.
It is possible to use a larger toothed wheel 30 (or 102) with more teeth 38, a gear driven toothed wheel 30 (or 102) or more complex and expensive measuring components. However, the combination of the preferred embodiment provides information which is easily executed by the processor 50, and is compact, durable, and inexpensive.
In the preferred embodiment, device 10 (or 100) can accumulate information for up to 99 plant spaces per sample, and can give a continuous readout of population per acre, standard deviation of plant spacing, and number of plant distances measured. It is sometimes beneficial to know whether all the values of plant spacing are concentrated at the "average" or spread out all over the place, i.e., an indication of how variable the body of the sampled data tends to be. The customary measure of variability is the standard deviation. Standard deviation of plant spacing is an indication of the variability of the plant spacing values making up the sample, but it is likely to be a biased estimator of the variation of plant spacing values within the entire plant population. Each time a sample is terminated, these quantities are stored in RAM memory 54 for later recall. Up to 99 samples can be stored. It is to be understood, however, that different components, numbers of stored plant spaces, and samples are possible.
The operation of the embodiment of the present invention shown in FIGS. 11-13 is similar to the operation of the embodiments shown in FIGS. 1-7. The sensors 226 measure the plant population and spacing variability in each row that the combine 220 harvests by sensing the distance between successive plants and determining calculations based on the accumulated measurements. As described above, each sensor 226 has a corresponding processor or microcontroller which communicates with the central controller 228. The central controller 228 takes the data from the sensor 226 and communicates to the yield monitor 232 to provide the yield monitor with plant population and spacing data, etc. The central controller 228 is also connected to a display 240 which can notify the operator of the combine when a row is plugged or is not being fed into the combine head 222 for any other reason.

Human Zoos West Colonies Ethnological ExpositionsThe displays often emphasized the cultural differences between Europeans of Western civilisation and non-European peoples. Ethnographic zoos were often predicated on unilinealism, scientific racism and social Darwinism. A number of them placed indigenous people (particularly Africans) in a continuum somewhere between the great apes and humans of European descent. Ethnographic zoos have since been criticized as highly degrading and racist.
First human zoos
In the Western Hemisphere, one of the earliest-known zoos, that of Moctezuma in Mexico, consisted not only of a vast collection of animals, but also exhibited unusual humans, for example, dwarves, albinos and hunchbacks.
During the Renaissance, the Medicis developed a large menagerie in the Vatican. In the 16th century, Cardinal Hippolytus Medici had a collection of people of different races as well as exotic animals. He is reported as having a troup of so-called Barbarians, speaking over twenty languages and there were also Moors, Tartars, Indians, Turks and Africans.
One of the first modern public human exhibitions was P.T. Barnum's exhibition of Joice Heth on February 25, 1835 and, subsequently, the Siamese twins Chang and Eng Bunker. These exhibitions were common in freak shows. However, the notion of the human curiosity has a history at least as long as colonialism. For instance, Columbus brought indigenous Americans from his voyages in the New World to the Spanish court in 1493. Another famous example was that of Saartjie Baartman of the Namaqua, often referred to as the Hottentot Venus, who was displayed in London and France until her death in 1815. During the 1850s, Maximo and Bartola, two microcephalic children from Mexico, were exhibited in the US and Europe under the names Aztec Children and Aztec Lilliputians. However, human zoos would become common only in the 1870s in the midst of the New Imperialism period.
1870s to World War II
Exhibitions of exotic populations became popular in various countries in the 1870s. Human zoos could be found in Paris, Hamburg, Antwerp, Barcelona, London, Milan, New York, and Warsaw with 200,000 to 300,000 visitors attending each exhibition. In Germany, Carl Hagenbeck, a merchant in wild animals and future entrepreneur of many European zoos, decided in 1874 to exhibit Samoan and Sami people as "purely natural" populations. In 1876, he sent a collaborator to the Egyptian Sudan to bring back some wild beasts and Nubians. The Nubian exhibit was very successful in Europe and toured Paris, London, and Berlin. He also dispatched an agent to Labrador to secure a number of Esquimaux (Eskimo) (Inuit) from the settlement of Hopedale; these Inuit were exhibited in his Hamburg Tierpark.
Geoffroy de Saint-Hilaire, director of the Jardin d'acclimatation, decided in 1877 to organize two ethnological spectacles that presented Nubians and Inuit. That year, the audience of the Jardin d'acclimatation' doubled to one million. Between 1877 and 1912, approximately thirty ethnological exhibitions were presented at the Jardin zoologique d'acclimatation.
Both the 1878 and the 1889 Parisian World's Fair presented a Negro Village (village nègre). Visited by 28 million people, the 1889 World's Fair displayed 400 indigenous people as the major attraction. The 1900 World's Fair presented the famous diorama living in Madagascar, while the Colonial Exhibitions in Marseilles (1906 and 1922) and in Paris (1907 and 1931) also displayed humans in cages, often nude or semi-nude. The 1931 exhibition in Paris was so successful that 34 million people attended it in six months, while a smaller counter-exhibition entitled The Truth on the Colonies, organized by the Communist Party, attracted very few visitors—in the first room, it recalled Albert Londres and André Gide's critics of forced labour in the colonies. Nomadic Senegalese Villages were also presented.
Native people of Suriname were displayed in the International Colonial and Export Exhibition in Amsterdam, held behind the Rijksmuseum in 1883.
Similar human displays had been seen at the 1901 Pan-American Exposition and at the 1893 World's Columbian Exposition, where Little Egypt performed bellydance, and where the photographers Charles Dudley Arnold and Harlow Higginbotham took depreciative photos, presenting indigenous people as catalogue of "types," along with sarcastic legends.
To increase the number of visitors, the Cincinnati Zoo invited one hundred Sioux Native Americans to establish a village at the site in 1896. The Sioux lived at the zoo for three months.
In 1904, Apaches, Igorots (from the Philippines) and the famous Ota Benga were displayed, dubbed as "primitive", at the Saint Louis World Fair. The USA had just acquired, following the Spanish-American War, new territories such as Guam, the Philippines, and Puerto Rico, allowing them to "display" some of the native inhabitants. According to the Rev. Sequoyah Ade,
To further illustrate the indignities heaped upon the Philippine people following their eventual loss to the Americans, the United States made the Philippine campaign the centrepoint of the 1904 World's Fair held that year in St. Louis, MI . In what was enthusiastically termed a "parade of evolutionary progress," visitors could inspect the "primitives" that represented the counterbalance to "Civilisation" justifying Kipling's poem "The White Man's Burden". Pygmies from New Guinea and Africa, who were later displayed in the Primate section of the Bronx Zoo, were paraded next to American Indians such as Apache warrior Geronimo, who sold his autograph. But the main draw was the Philippine exhibit complete with full size replicas of Indigenous living quarters erected to exhibit the inherent backwardness of the Philippine people. The purpose was to highlight both the "civilising" influence of American rule and the economic potential of the island chains' natural resources on the heels of the Philippine-America War. It was, reportedly, the largest specific Aboriginal exhibit displayed in the exposition. As one pleased visitor commented, the human zoo exhibit displayed "the race narrative of odd peoples who mark time while the world advances, and of savages made, by American methods, into civilized workers."
In 1906, socialite and amateur anthropologist Madison Grant, head of the New York Zoological Society, had Congolese pygmy Ota Benga put on display at the Bronx Zoo in New York City alongside apes and other animals. At the behest of Grant, a prominent eugenicist, the zoo director William Hornaday placed Ota Benga displayed in a cage with the chimpanzees, then with an orangutan named Dohong, and a parrot, and labeled him The Missing Link, suggesting that in evolutionary terms Africans like Ota Benga were closer to apes than were Europeans. It triggered protests from the city's clergymen, but the public reportedly flocked to see it.
Benga shot targets with a bow and arrow, wove twine, and wrestled with an orangutan. Although, according to the New York Times, "few expressed audible objection to the sight of a human being in a cage with monkeys as companions," controversy erupted as black clergymen in the city took great offense. "Our race, we think, is depressed enough, without exhibiting one of us with the apes," said the Reverend James H. Gordon, superintendent of the Howard Colored Orphan Asylum in Brooklyn. "We think we are worthy of being considered human beings, with souls."
New York Mayor George B. McClellan, Jr. refused to meet with the clergymen, drawing the praise of Dr. Hornaday, who wrote to him, "When the history of the Zoological Park is written, this incident will form its most amusing passage."
As the controversy continued, Hornaday remained unapologetic, insisting that his only intention was to put on an ethnological exhibit. In another letter, he said that he and Madison Grant, the secretary of the New York Zoological Society, who ten years later would publish the racist tract The Passing of the Great Race, considered it "imperative that the society should not even seem to be dictated to" by the black clergymen.
Still, Hornaday decided to close the exhibit after just two days, and on Monday, September 8, Benga could be found walking the zoo grounds, often followed by a crowd "howling, jeering and yelling."

Megg Jensen the other day while trying to figure out what publishing route I want to take. Megg writes YA like me and that alone is what stopped me. I read through a few posts, read part of the sample of her novel (which I highly enjoyed and want to read more) and discovered she went with e-pub and her first book is out on Amazon Kindle and B&N Nook AND she will have her book in paperback too. All three are formats every author should desire right now. Ebooks are taking off, more and more people are buying Nooks, Kindles and eReaders so naturally our books should be available in those formats.
I'm getting sidetracks from my point.
Seeing how Megg is in the genre I am and she has succeeded in getting her book out there I dropped her a line asking if she would do a guest post. She said YES! So, dear readers, keep your eyes open. Megg will be dropping by with her story and hopefully between me and her we can figure out a prize for a contest too.

Having problems with your ASUS G50VT-X6 PC Notebook ?
World of Warcraft laptop Issues
\015 Hi everyone! I was wondering if any of you could help me with my laptop, Vista, and World of Warcraft. I've been having a little bit of trouble getting World of Warcraft to work on my Asus G50Vt-x5 laptop. The specs are capable of running the game, but I have a feeling Vista is to blame. I've downloaded the game twice already, but each time I log in, it says an update was installed successfully and then asks me to restart world of warcraft. When I exit world of warcraft it then opens up a brand new window and begins to reinstall world of warcraft despite the fact that it is already on my laptop. Is this normal? I just don't know what can be wrong. This gaming laptop was even advertised with WoW wrath of the lich king a few weeks ago so I'm sure that it works with it. please help\015
Answers :
Hello, when you begin to install it, do you install the updates? If that options is selectable, disable it and take the basic install, then after you're done, go into the menu to manually install updates.

Factory Island, Saco, ca. 1840Item 28931 info
In 19th-century New England, the growth of textile factories propelled the industrial revolution. Beginning in the 1830s, mill managers recruited young women to leave their homes and work in the factories.
Young women -- native born, single, and in their late teens to early twenties -- comprised the majority of the labor force in the textile mills from the 1830s to the 1850s.
Worried parents were assured their daughters would be safe far from home, housed in company-owned boarding houses under the watchful eye of an older woman, often a widow, who ran the boardinghouse.
Strict rules and curfews would keep these daughters of New England safe from harm.
Berengera Caswell [?], ca. 1849Item 29132 info
Maine Historical Society
With two of her sisters, Berengera Caswell (1828-1849), like thousands of young New England women, traveled to the textile factories seeking an independence and cash-paying work previous generations of women rarely experienced.
Girls in past generations spent their days spinning thread, weaving cloth, and making candles and other household products.
By the early 19th century in more settled areas, these goods were affordable and readily available for purchase. With less household tasks to do, factory work permitted young women to be an economic asset rather than an economic drain.
Spinning Room of Pepperell Mills, Biddeford, 1910Item 23522 info
McArthur Public Library
Berengera worked in the carding room of the Amoskeag mill in Manchester, New Hampshire, putting in 12-hour days and earning on average $3.25 per week.
Despite the long days, textile operatives enjoyed many evening activities including shopping, exhibitions, lectures, and strolling along the factory canals.
In the early summer of 1849, Caswell met a young machine operative named William Long. Their relationship became intimate over the summer – a behavior of which middle class moralists highly disapproved.
Shuttle, Pepperell Mills, Biddeford, ca. 1910Item 28922 info
Dyer Library Archives / Saco Museum
Thais Elizabeth Caswell, Berengera's sister, worked as a weaver at the Amoskeag mill in Manchester.
Weaving was a highly paid position in textile work and in the course of two years, Thais earned over $400.
Berengera's beau, William Long, was less diligent in his work habits and was fired in September of 1849.
Long returned to his hometown of Biddeford, while Berengera left Manchester and moved to Salem, Massachusetts.
Thais remained in New Hampshire. When Berengera left, it was the last time the two sisters would see each other.
Mills, Saco, ca. 1875Item 28764 info
Dyer Library Archives / Saco Museum
By November 1849, Berengera Caswell realized she was pregnant and she traveled to Biddeford to find William Long.
If they married, the social stigma of unwed motherhood would be removed.
If they did not, Berengera would be considered a fallen woman, forever shamed with an illegitimate child.
William sought the advice of his Biddeford mill manager who suggested a third possibility, a legal, but not openly discussed option: an abortion.
Storer Street, Saco, ca. 1880Item 25550 info
Dyer Library Archives / Saco Museum
Long and Caswell turned to Dr. James Smith, a Saco physician who practiced from his Storer Street home.
Smith, who gave Caswell the alias Mary Bean, treated her with herbal preparations that had been used by healers for centuries, but these failed to work.
In December 1849, Smith attempted a dangerous surgical procedure. This resolved Caswell's dilemma, but the operation left her horribly infected in an era without antibiotics.
A week later, she died.
Medicine kit, Portland, ca. 1860Item 28979 info
Maine Historical Society
At mid-century, numerous medical philosophies guided a variety of physicians, midwives, and healers.
Allopathic physicians, today's M.D.s, were trained in medical schools such as that at Harvard or Dartmouth.
These doctors, called "regular" physicians, used several unpleasant techniques including bleeding, leeches, and blistering.
Medicine included harsh purgatives and stimulants that often left patients debilitated.
The allopaths, however, had professional power in the American Medical Association, founded in 1847 to support the regular physicians' medical ideas and practices.
Homeopathic Medicine Box, Fryeburg, ca. 1850Item 28980 info
Maine Historical Society
Botanic physicians learned their craft from apprenticeships, books, or short courses.
These doctors favored herbal remedies and treatments much less harsh to the patient's body.
Dr. James Smith was one of 10 physicians identified in the 1849 Saco Directory: two, including Smith, were botanic, one Thompsonian, and seven identified as allopathic. There were also several apothecaries and a dentist.
The number and diversity of medical providers reflects the intense competition in the health business at mid century.
York County Courthouse, 1894Item 22685 info
Alfred Historical Committee
Although abortion was a legal procedure in 1849, Caswell's subsequent death was considered a crime.
With public suspicion already aroused by Smith's practice, the doctor attempted to conceal Caswell's death by tying her to a board and placing her in a brook that fed into the Saco River.
His plan was foiled when the board became wedged as the brook passed underneath Storer Street.
In April 1850, Caswell's body was discovered and Smith was charged with murder.
Hundreds of residents from across southern Maine followed the sensational case and waited outside the courthouse for the latest information.
Nathan Clifford, Newfield, ca. 1880Item 12294 info
Maine Historical Society
Newfield native Nathan Clifford, who would be appointed to the U.S. Supreme Court in 1858, was Smith's appointed attorney.
Testimony from allopathic physicians confirmed Caswell's cause of death and statements from Storer Street neighbors placed Caswell at Smith's residence.
Caswell's younger sister Thais Elizabeth identified Berengera's possessions, still at Smith's home.
Smith was convicted of second-degree murder and sent to the Maine State Prison.
Clifford filed an appeal. Abortion law was changing in the 1850s and based on a conflict between evolving statutory law and common law, Smith's conviction was overturned.
The AMA used cases such as this to revise abortion law in the 1850s, making the practice illegal until the passage of Roe v. Wade in 1973.
Cover, 'Mary Bean or the Mysterious Murder,' 1851Item 29272 info
New Hampshire Historical Society
Caswell's death confirmed the worst fears of the middle class: that young women, who should have their eyes on marriage and motherhood, would suffer ill health, moral injury, and even death if they remained in the work force.
Sensational fiction profited on these fears by offering moralistic tales of naïve young women ruined at the hand of cruel seducers.
Berengera Caswell's life and death became fodder for two such works, although the anonymous author of this tale took great liberties to make her story fit cultural expectations of innocent girls wronged by cads preying on unsupervised young women.
The moral of the story: to be safe, girls should remain at home.
Cover, 'Confession of George Hamilton,' 1852Item 29273 info
Maine Historical Society
While young women were inevitably the victims in these salacious tales, young men were cautioned as well.
The new cities were seen as dangerous places where young men could be duped by "confidence men" who appeared to be mentors but were in reality focused only on dragging youth down a path of drunkenness, gambling and crime.
Stating that these sensational tales were published only to guide and protect impressionable youth, publishers churned out thousands of these tales, making good money on the latest "shocking crime" or "horrible tragedy."
The Saco Factory Girl and Emily Adderson Romances of Real Life, 1852Item 29089 info
Dyer Library Archives / Saco Museum
Saco and Biddeford were the setting for several works of fiction featuring the sad fate of wronged factory girls.
This tale features the impetuous Caroline who ignores her mother, lies to her parents, and runs away with her beau.
She is seduced, abandoned before marriage, robbed of all her goods, and ends her days in a brothel.
Caroline's seducer uses the stolen money to travel to California in the gold rush but this confidence man is himself conned and he dies alone in Panama, birds of prey waiting for his corpse.
Story after story reiterated that factory work for young women was temporary at best and that safety --- for young women and for middle class culture – was found in the domestic setting of home.
Pepperell Workers, Biddeford, ca. 1900Item 23038 info
Dyer Library Archives / Saco Museum
At mid century, ongoing labor strife and rising tension between mill owners and their increasingly savvy female work force led to a shift in the composition of mill workers.
By 1860, the majority of factory girls were foreign born and the native Protestant middle class society was less concerned with their fates. Mill owners paid this work force less and demanded more work of them as the textile industry became less profitable.
Following the upheaval of the Civil War, native born, middle class young women found new opportunities that took them from their homes, delayed marriage, and worried their parents.
Once again sensational fiction moralized on the dire consequences of this latest quest: attending college.

e-Snake Scooter that Tilts
The e-Snake is a scooter that is powered by lithium ion batteries. The scooter features a tilting mechanism which allows it to corner quicker while keeping the back wheels on the floor. It participated in Formula Electric and Hybrid in Italy last year and was awarded top marks for acceleration and speed. With it being electric, the scooter weighs quite a bit at 357 pounds. With that hefty weight it can still have a range of 62 miles which is ample for most people travelling to and from the office each day.
If it could be just made lighter, which might not be possible with the lithium ion batteries, I am sure it could get a far greater range. However, it's not the best looking scooter I have seen. If you like to be green, then it could be ideal for you. Top speed of the tilting scooter is 31 MPH.

Here are a few things I've made in the past couple weeks from free internet patterns:
Watch Cap - leftover yarn from my stash that I dyed with Koolaid. The very end of the top decrease turned out wonky and I forgot to guage (shame! shame!) so this is going to the charity box.
Snowflake Hat - kettle dyed Patons Classic Merino using Wilton's. This is a Christmas present for my 1.5 year old niece. The free pattern is from Little Turtle Knits.
Kitchen Dishie - I didn't dye this. :) It's good old Sugar N Cream. Another Christmas present . . . I've got another one 1/2 done and several more to go.

Wilmington Fire of 1864
I would be correct to say that more buildings that would today be great historical building were destroyed by fire, surely the fire that destroyed our State House (capitol) in 1831 and the fire that almost destroyed Fayetteville, also in 1831 were two great losses to North Carolina.
The fire that occurred in Wilmington on April 30, 1864 was one of the state's greatest losses. Looking at the date, you realize that North Carolina was a part of the Confederate States of America. Wilmington was the state's largest shipping and receiving point. Blockade running was big business during the Confederate years, and Wilmington was the last seaport of the Confederate States.
In the early morning hours of April 30, 1864, a fire broke out in a warehouse on the West Side of the Cape Fear River. In short order the entire West Side of the river was in flame, with all the warehouses and building, plus the Wilmington and Manchester Railroad were in flame. One of the greatest loses as a result of this fire was cotton, which was to be shipped to England for the Confederate war effort. In all, over 4,624 bales of cotton were destroyed by fire, amounting to over 4 million dollars. The Wilmington newspaper stated; "when the true loss is know it is probable that the figure will reach over six million dollars." As far as known, the fire officials do not know if the fire was accidental or not.

TSR ups hurricane activity forecast, Accuweather warns on landfall potential
Tropical Storm Risk has increased its forecast for 2017 Atlantic Tropical Storm & Hurricane Season activity, joining others in predicting a more active year. Meanwhile Accuweather is warning of landfall risks for the United States coastline and early season storm potential.
Earlier this year, Tropical Storm Risk (TSR), the climatological research group backed by University College London, Aon Benfield, and Crawford & Company, and other forecasters of Atlantic tropical activity were reducing their forecasts in the expectation that we would see a weak El Niño form by the time of the typical peak of the season, suggesting a slower year for activity.
The El Niño forecasts have moved somewhat and perceptions of the state of sea surface temperatures have also adjusted in recent weeks, meaning that most forecasters are increasing their predictions for 2017 hurricane activity in their latest updates.
Lower hurricane forecasts are positive for reinsurance and ILS interests, although just one major storm would be required for traditional reinsurers to suffer a major impact to their capital adequacy, while ILS and catastrophe bond investors could face significant claims.
TSR had forecast that the 2017 season would see 11 named tropical storms, 4 hurricanes and 2 major hurricanes of category 3 strength of greater.
This has now been increased to 14 tropical storms, 6 hurricanes and 3 major hurricanes, which is more aligned with the longer term averages and very close to the recent 10 year climate norm.
Professor Mark Saunders and Dr Adam Lea explained the change in forecast; "The TSR forecast has increased since early April 2017 due to the recent trend towards negative North Atlantic Oscillation conditions which favour warmer hurricane main development waters in August-September, and to the decreased likelihood that El Niño conditions will develop by August- September."Here is the current Sea Surface Temperature Anomaly map from Unisys Weather. Notable points are 1) the equator off South America's bulge: No El Niño yet and 2) the heating off the U.S. East Coast which, if it remains, could be fuel for storms turning up the eastern seaboard.
Adding the latest TSR prediction into our tracked forecaster mix gives us an increased Artemis average forecast for the 2017 hurricane season of 12.3 named storms, 5.7 hurricanes and 2.6 major hurricanes.
The forecasters at TSR explained that the changing view of El Nino potential for 2017 means; "There is an increased likelihood for lower trade wind strength, increased vorticity and lower vertical wind shear where hurricanes form; factors which all translate into increased hurricane activity.
However, they warn that both factors, El Nino and warmer sea surface temperatures, contain significant uncertainty, particularly; "Whether El Niño conditions will develop and how warm the tropical North Atlantic will be in August-September."...MORE
