The present invention relates generally to acoustic vibrators used for frequency control and selection, and more particularly to piezoelectric resonators having variable sensitivity and compensation for external acceleration effects.
Acoustic resonators for precise selection and control of radio frequencies are well known in high sensitivity sensor circuitry, such as accelerometers. The two most common types of acoustic vibrators are the bulk acoustic wave devices (BAW) and surface acoustic wave devices (SAW).
A perspective view and a side view of a typical BAW are shown in FIGS. 1 and 2 respectively. The BAW includes a piezoelectric plate as a substrate 100, a top electrode 102 on one surface of the substrate and a bottom electrode 104 on the opposite surface. When the electrodes 102, 104 are energized, usually by RF signals, an electric field is created. The mechanical forces inherent to the electric field stress the piezoelectric substrate producing a pattern of strain known as a mechanical mode shape.
The alternating RF signal creates vibration in the mechanical mode shape, resulting in acoustic waves. The acoustic waves travel through the thickness of the piezoelectric plate, reflecting at the surfaces and setting up standing waves throughout the interior of the plate. The acoustic waves are confined essentially to the active region 106 between the two electrodes 02, 104, and drop off sharply outside of the region occupied by the electric field created by the energized electrodes 102, 104. The frequency of a BAW is expressed approximately as ##EQU1## where n is the overtone number, an odd integer (1, 3, 5 . . .)
t is the plate thickness
ρ is the material density
c is the piezoelectrically stiffened elastic constant
In general, n, t and ρ will be invariant during operation. However, c may vary as the result of a number of factors, thus altering the frequency of the BAW.
A typical surface acoustic wave device (SAW), is shown in FIG. 3. Energized electrodes create a mechanical mode shape and resulting acoustic waves, similar to a BAW. However, the electrodes 202, 204 of a SAW are arranged on only one side of piezoelectric substrate 200, and the acoustic waves are confined to the surface of the substrate 200 having the electrodes. As with the BAW, the RF signal electrodes are arranged in sets. However, the acoustic waves travel only in the area of the surface of the piezoelectric substrate bounded by RF signal electrodes 202, 204 and grating reflectors 206. The edges of the substrate outside this area are essentially at rest.
The first set of electrodes 202 is fed by a voltage source 208 and the second set of electrodes 204 is grounded. The electrodes are configured to have bus bars such as 202b, 204b and fingers such as 202a, 204a. The electrode sets 202, 204 are interdigitated as shown so that acoustic waves move from the fingers of one electrode set to adjacent fingers of the second electrode set. The grating reflectors 206 are used to control the extent of acoustic wave propagation over the surface of the piezoelectric substrate. Additional sets of electrodes 210, 212 and grating reflectors 214 can be arranged on the surface of the piezoelectric substrate according to the demands of the system containing the SAW.
The frequency of a SAW is roughly expressed as: ##EQU2## where d is the inter-digitated finger spacing for both the interdigitated transducers (IDT) and the grating reflectors, c is similar to the piezoelectrically stiffened elastic constant used in the formula for the BAW, and ρ is similar to the constant used in the formula for the BAW.
As in a BAW, the factors d and ρ are essentially
during operation. However, the elastic stiffness, c, may vary as the result of other factors, thus altering the frequency of the SAW.
In both BAW and SAW devices, a mechanical mode shape is, in part, determined by the elastic stiffness, c, of the piezoelectric substrate. In turn, the mechanical mode shape when combined with all the stresses exerted on the piezoelectric substrate determines the precise frequency at which the device will operate.
Under static conditions all the stresses applied to the piezoelectric substrate are accounted for by the mechanical mode shape which remains constant during operation. However, additional stresses can be introduced when the piezoelectric substrate is accelerated, decelerated or vibrated. Since high precision circuitry using acoustic vibrators is often needed in violently moving vehicles, such as helicopters, compensation for external acceleration becomes critical. Since acoustic vibrators are also used in accelerometers, variable sensitivity is necessary to quickly adjust to rapidly changing external conditions.
The prior art teaches a number of methods of compensating for stresses caused by external acceleration. One technique is to add or delete material from the electrodes altering the mechanical mode shape. Examples of such techniques are found in U.S. Pat. Nos. 4,837,475 and 4,836,882.
Another technique uses alteration of the operating frequency to change the mechanical mode shape and thus compensate for external stresses. An example of this technique is found in the publication by Ballato et al entitled, "ELECTRONIC DESENSITIZATION OF RESONATORS TO ACCELERATIONS", Forty-Fourth Annual Symposium on Frequency Control, U.S. Army Electronics Tech. & Devices Laboratory, pp. 444-451.
In yet another technique, additional multi-electrode structures are used to vary mechanical mode shape and thus alter sensitivity to external accelerations. An example of this technique is found in the publication by Smythe & Horton entitled, "ADJUSTMENT OF RESONATOR G-SENSITIVITY BY CIRCUIT MEANS", Forty-Fourth Annual Symposium on Frequency Control, Piezo Technology, IEEE (1990), pp. 437-443.
A further technique includes calculating optimal electrode masses and configurations for certain types of acceleration, and limiting the design of the acoustic vibrators to only those configurations having the least acceleration sensitivity. An example of this technique is found in the publication by Lee and Guo entitled "ACCELERATION SENSITIVITY OF CRYSTAL RESONATORS AFFECTED BY THE MASS AND LOCATION 0F ELECTRODES", Forty-Fourth Annual Symposium on Frequency Control, Dept. of Civil Engineering & Operation Research, IEEE (1990), pp. 468-473.
Each of the aforementioned systems suffers from lack of flexibility. For some there are severe limitations in usable frequencies or electrode configurations. Rapidly and easily altering acoustic vibrator sensitivity is problematical for all of them.
A more adaptable system providing rapid compensation to external stresses is taught in U.S. Pat. No. 4,453,141, to Rosati, using a dynamic suppression system for doubly-rotated cut quartz BAW resonators. This system detects externally induced vibrations on the piezoelectric substrate and generates an electrical signal which is a replica of the vibration acting on the substrate. The electrical signal is thereafter modified and applied directly to the RF electrodes to immediately compensate for the externally induced vibrations. An isolation network is necessary for the proper operation of this system, as is a doubly-rotated cut quartz substrate. The Rosati system depends on "electroelastic" operation and so cannot be used with singly rotated cut quartz. This system is also not adaptable to SAW devices, and cannot use many electrode configurations.
One object of the present invention is to quickly and efficiently compensate for stresses caused by external acceleration on an acoustic vibrator.
Another object is to operate a responsive variable sensitivity acoustic vibrator.
Yet another object is to rapidly vary sensitivity for both SAW and BAW devices, having a wide variety of electrode configurations, operating frequencies, and employing both singly rotated cut and doubly-rotated cut quartz.
A further object is to compensate for stress caused by external acceleration on an acoustic vibrator without altering mechanical mode shape or operating frequency of the acoustic vibrator.
Still a further object of the invention is to remove any chance of interference between radio frequency signals and stress compensating signals.
According to the present invention, an acoustic vibrator subject to external stresses includes a substrate, a first electrode means for creating a mechanical mode pattern using the substrate material and a second electrode means for generating bias stresses. The mechanical mode pattern has a predetermined characteristic frequency which is not changed by the stresses generated by the second electrode means to compensate for external stresses applied to the substrate.
FIG. 1 is a perspective view of a bulk acoustic wave device.
FIG. 2 is a side view of a bulk acoustic wave device.
FIG. 3 is a perspective view of a surface acoustic wave device.
FIG. 4 is a perspective view of the present invention, showing a static biasing arrangement.
FIG. 5 is a perspective view of the present invention having interdigitated biasing electrodes.
FIG. 6 is another aspect of the present invention used on a surface acoustic wave device.
FIG. 7 is a top view of a bulk acoustic wave device showing stress bias vectors.
FIG. 4 shows an embodiment of the present invention applied to a BAW resonator. RF signal electrodes 402A and 402B are mounted on opposite sides of piezoelectric substrate 400. The RF electrodes are fed by RF oscillator circuit 404 in a manner common to conventional BAW devices. A series of biasing electrodes 406A-H is mounted around the edges of the upper and lower major surfaces of substrate 400. Electrodes 406A-H are individually biased by adjustable DC sources 408A-H.
Biasing electrodes 406A-H, when energized, produce additional stresses within the piezoelectric substrate 400. These stresses do not interfere with the mechanical mode shape which is confined to the region between the two RF electrodes 402A and 402B. However, the additional stresses are effective to offset stresses introduced by external acceleration forces applied to the substrate.
The configuration of biasing electrodes 406A-H can be tailored for any shape of piezoelectric substrate, and can be arranged to allow imposition of biasing stresses in virtually any direction by the proper choice of potentials and polarities of the voltages applied to the biasing electrodes 406A-H. An important aspect of the invention is that the RF signals applied to the electrodes 402A, 402B need not be altered to compensate for externally applied stresses since the biasing stress electrodes provide all the stress vectors necessary for compensation.
Different types of piezoelectric material are affected differently by the stresses applied to them. Consequently, some materials are unsuitable for use at certain frequencies or in certain environments or with certain electrode configurations. The most common material used in piezoelectric devices is quartz. The properties of quartz devices depend on the cut or orientation from which the device is made. The most commonly available quartz is generically known as singly rotated cut quartz. These types of quartz include AT and BT type cuts. Another type of quartz is known as doubly rotated cut quartz. An example of a doubly rotated cut quartz is an SC cut quartz crystal. The present invention can be used with both singly rotated cut and doubly rotated cut crystals.
The static biasing arrangement in FIG. 4 is adjusted by first measuring the RF output from RF electrodes 402A, 402B when the vibrator is subjected to a known externally-induced vibration or acceleration. The DC biases are then adjusted to compensate for the effects of the externally-induced stresses. The DC biases may also be adjusted to vary the acceleration sensitivity of the acoustic vibrator so that it may respond to externally introduced stresses and the use as an accelerometer. Because of the variable biasing electrode arrangement allowed by the present invention, virtually any particular vector of stress can be compensated for (or enhanced by the case of accelerometers) by the proper biasing.
A particularly effective arrangement for generating compensating stress vectors in almost any direction is shown in FIG. 7, a top view of an electrode arrangement similar to that in FIG. 4. Pairs of stress biasing electrodes 706, 708 and 710, 712 generate orthogonal lines of stress 720, 730. More than one pair of orthogonal lines of stress can be generated. However, biasing fields may be generated across the active region between overlapped RF signal electrodes 702, 704. In some cases this may interfere with the mechanical mode shape produced by electrodes 702, 704.
This situation can be avoided by the use of interdigitated electrodes used as biasing electrodes as shown in FIG. 5. Interdigitated biasing electrodes 504A and 504B are similar to those used on SAW devices. However, they are not used as part of the RF signal circuitry. Each set of interdigitated electrodes 504A, 504B is connected as shown in FIG. 5 with one electrode 504A connected to a voltage source 520 and the other electrode 504B connected to ground potential. Other interdigitated sets of electrodes 506A, 506B are arranged in the same configuration as that shown in FIG. 4.
The interdigitated biasing electrodes of FIG. 5 also lend themselves to dynamic biasing using a time-varying biasing field. Dynamic biasing is well known and a variety of sensing and feed-back circuits are available. An example of such circuitry is shown in the Rosati patent incorporated herein by reference. An important factor of the present invention is that the feed-back circuitry connected to the biasing electrodes is separate from the RF signal generator connected to the RF signal electrodes. Since the sensing circuitry supplies a constant stream of information in the form of error signals to the feed-back circuit, constant compensation to varying conditions is made by the biasing electrodes. As a result, instantaneous frequency variations can be reduced to zero. The separation of the two types of circuitry prevent interference between the RF signals and the biasing voltage.
The present invention is equally applicable to a SAW device as shown in FIG. 6. SAW devices provide for a greater variety of electrode configurations, frequency variations and uses other than BAW devices. The piezoelectric substrate 600 in FIG. 6 contains two sets of RF signal electrodes 602A, 602B and 604A, 604B. However, more sets of RF signal electrodes can be used depending upon substrate and system requirements. Biasing electrodes 606, 607, 610 and 612 are located along the periphery of the piezoelectric substrate 600. The biasing electrodes may be arranged to enclose the entire periphery of this substrate. The biasing electrodes may also be located on the opposite side of the substrate from the RF signal electrodes.
Although not shown, separate signal sources are connected to the RF signal electrodes and the biasing electrodes. voltages applied to the biasing electrodes 606, 607, 610 and 612 will be determined by a dynamic biasing system responsive to changing environmental conditions producing stresses on piezoelectric substrate 600. Signals applied to the RF signal electrodes 602A and 602B and 604A and 604B are not altered in response to externally-applied stresses.
Although a number of arrangements of the invention have been mentioned by way of example, it is not intended that the invention be limited thereto. Accordingly, the invention should be considered to include any and all configurations, modifications, variations, combinations or equivalent arrangements falling within the scope of the following claims.

It's the next best thing to a space walk!
The 3D models in this app are based on photos taken by NASA spacecraft and ground based telescopes. Because some of the moons around the gas giants have only been visited once or twice, we may have partially complete images. Missing surface detail for these objects is estimated from what can be seen.
In this solar system simulator you can explore the brilliant blue-green Uranus, knocked onto its side by a massive collision. Visit the proto-planet Ceres which makes up one third of the mass of the asteroid belt. Marvel at Neptune's moon Triton which orbits in the opposite direction to Proteus. Take in the sights of the Jupiter's heavily scarred moon Callisto, its surface pockmarked by countless impact craters.
Places to visit in this solar system orrery:
The Sun, otherwise known as Sol
Planets: Mercury, Venus, Earth, Mars
Gas giant: Jupiter, Saturn, Uranus, Neptune
Moons: Luna, Deimos and Phobos, Callisto, Europa, Ganymede, Io, Mimas, Tethys, Enceladus, Dione, Rhea, Titan, Iapetus, Miranda, Umbriel, Ariel, Oberon, Titania, Triton, Proteus, Charon

|Sara Teasdale 1884-1933
This post goes out to my sweet friend of many years, Laura Kvasnosky, who recently gave me a slim volume of poetry by Sara Teasdale, published in 1926, and titled Dark of the Moon. Here is my favorite poem from it:
On the Sussex Downs
Over the downs there were birds flying,
Far off glittered the sea,
And toward the north the weald of Sussex
Lay like a kingdom under me.
I was happier than the larks
That nest on the downs and sing to the sky,
Over the downs the birds flying
Were not so happy as I.
It was not you, though you were near,
Though you were good to hear and see,
It was not the earth, it was not heaven,
It was myself that sang in me.
--Sara Teasdale
I've always thought memorizing poems was a fine thing to do, and I recommend this one for memorization. It seems to me as golden as any prayer to say each night as you fall asleep or each morning as you get up.===========================
The Poetry Friday Round-up is being hosted this week by Donna over at Mainely Write. Head over there to see what other people have posted.

Montauban v Sale: Teams
At Stade Sapiac, Saturday December 13, kick-off 6pm
Last Updated: 12/12/08 3:08pm
Tait: Starting at full-back
Sale Sharks have named England international duo Andrew Sheridan and Mathew Tait in their starting XV to face Montauban.
Sheridan returns to the starting line up for his first start since playing in Sharks' defeat at London Irish in October.
Mathew Tait also starts at full-back, in place of the injured Rory Lamont and Luke Abraham returns after injury.
Victory for the Sharks would see them take another giant step towards qualifying from Pool One and securing their place in the Heineken Cup quarter-finals.
Director of rugby Philippe Saint Andre said, "We are under no illusion that Friday evening's game will be much tougher than last weeks win over Montauban.
"They may have lost their opening three games but there is a lot of pride at stake for them and we are expecting a very tough 80 minutes.
Under strength
"Group A is wide open but if we want to get out of it and qualify for the quarter finals we have to aim to win all our remaining games.
It's no good trying to rely on going through as a 'best second placed club', Group A is by far the toughest group, no team has a 100 per cent record and we need to do our best to qualify."
Montauban coaches Laurent Labit and Laurent Travers have made ten changes to their team for the visit of Sale.
The French side has a far stronger look about it than the under strength team that travelled to England last weekend. Try-scoring machine Vilimoni Delasau is back on the wing and the big Fijian will be out to make an impact.
Skipper Marc Raynaud also returns to the back-row while the half-back combination of Cédric Rosalen and Fabrice Culinat remains intact.
Despite all the changes, this is arguably not Montauban's first team as Romanian scrum-half Petre Mitu is on the bench and first choice place-kicker Fabien Fortassin and French international Ibrahim Diarra are absent.
Montauban: 15 Sylvain Jonnet, 14 Yohann Audrin, 13 Jean-Philippe Viard, 12 Miguel Avramovic, 11 Vilimoni Delasau, 10 Cédric Rosalen, 9 Fabrice Culinat, 8 Marc Raynaud (c), 7 Yannick Caballero, 6 Antoine Battut, , 5 Rowan Frost, 4 Mattias Rolland, 3 Silviu Florea, 2 Brice Mach, 1 Bogdan Balan.
Replacements: 16 Goderzic Shvelidze, 17 Nick Adams, 18 Karim Ghezal, 19 Matthew Clarkin, 20 Jean-Emmanuel Cassin, 21 Régis Lespinas, 22 Petre Mitu.
Sale: 15 Mathew Tait, 14 Mark Cueto, 13 Andy Tuilagi, 12 Luke McAlister, 11 David Doherty, 10 Charlie Hodgson, 9 Richard Wigglesworth; 1 Andrew Sheridan, 2 Marc Jones, 3 Eifion Roberts, 4 Sebastien Chabal, 5 Dean Schofield, 6 Luke Abraham, 7 Neil Briggs, 8 JM Fernandez Lobbe (Capt).
Replacements 16 Stuart Turner, 17 Lionel Faure, 18 Brent Cockbain, 19 David Tait, 20 Dwayne Peel, 21 Chris Bell, 22 Nick McLeod.

Funk Styles: The Electric Boogaloo
It's not breakdancing. Not really, although it's associated with breakdancing nowadays; breakin' was originally seen as being very east coast, while these dances originated on the west coast. What was this dancing?Well, many of the most famous 70s-80s street moves are actually called funk styles, which were performed, at first, to funk and disco, and later to early electronic and industrial dance music. And the big daddy of them all was a dance called the Electric Boogaloo, and demonstrated by the Electric Boogaloos.Here they are in their zoot-suited glory, showing off their signature moves. [more inside]
Intelligent Dance Music Dancing
Oh, you know, just dancing in the rain
Electric Boogaloo (2): The True Electric Boogaloo
We've seen volcanic eruptions with lightning, heard the musical styles blending modern electro with the (samoan) sasa, and had a few snowclones of the phrasal play from Breakin' 2: Electric Boogaloo (a quick way to tag often unnecessary sequels; exhibits: A, B, C, D, and E), but no sign of the originals. Without further ado, I present The Electric Boogaloos. Float and glide on in for more. [more inside]
Japanese-style popping is dope - check out u-min and dancers on the Polysics I My Me Mine. The girl, Strong Machine 2, was only 11 years old at filming. And let's not forget the classic display of popping in Late at Night. But beyond these dancers who've achieved some commercial prominence, check out a few fun and stylized Japanese popping clips from lesser known but great dancers. [more inside]
Pop, Lock and Drop It
Remember the awesomeness that is Hilti & Bosch and Co-Thkoo? Well Robert Muraine is right up there with them. Who knew you could pop and lock rubber?
the more things change...
Parallels is a 10 minute dance video comparing current B-Boy poppin and lockin to vintage clips of African and global dance, jazz and swing, martial arts, and athletics. It's an excerpt from Detours - An Experimental Dance Collaboration, a video by dancer extraordinaire David "Elsewhere" Bernal. Via beans, beans, good for your heart [more]
Balloon popping photography at the Maker Faire
Here's a set of some great balloon popping photography from the Maker Faire this past weekend. My favorites: 1, 2, 3
lockin and loadin
Harder, better, stronger, faster - Hilty and Bosch, often called the masters of locking, pair up with Co-Thkoo to serve up 10 riveting minutes of dance. The routine to Daft Punk's classic starting about midway in the clip is brilliant. [more]

DragonFable is the sequel to AdventureQuest and has many improved gameplay features. Like other Artix games, DragonFable has turn based combat but supports up to 3v3 battles. While still a single player game, the ability to explore the game world rather than simply move from screen to screen make DragonFable feel much more like a complete RPG experience. The art style is similar to that of its predecessors but looks much sharper and with the ability to enter full screen mode, you may even forget you're playing a web based game. Since this is a single player game, there is a greater emphasis on story which is welcome. The casual and at times comedic dialogue helps keep the game interesting. There are three classes to chose from during character creation with more available as players advance in level. The starting classes are:
Fighter – A basic melee class with speciality in closed range combat. Fighters wear heavy armor and have skills that focus on increasing both physical and elemental resistance.
Mage – The basic magic user. Mages are armed with staffs but rely on elemental spells to defeat their enemies.
Rogue – Like Fighters, Rogues start out as mainly using close ranged attacks but possess ninja like skills such as double attack and smoke screen.

drones as a menace

Copping a 'copter
In the hands of criminals, small drones could be a menace. Now is the time to think about how to detect them and knock them down safely
In March, it [the French Government] held trials of anti-drone "detect and defeat" systems.

KANSAS CITY, Mo. - Jamaal Charles took the handoff on the first play of the game, skipped to his right and found a crease. He slipped through the hole, made a subtle cutback and then raced to the end zone.

KANSAS CITY, Mo. - Steve Breaston isn't sure why he hasn't been getting on the field for the Chiefs.

LOS ANGELES - Zack Greinke showed up alone to a mid-November meeting at Dodger Stadium, asking as many questions as he answered. When he left three hours later, the pitcher thought he may have found his new team while the Los Angeles Dodgers brass knew they had to land the top arm on the open market.

I have a list of data that I need to analyze. The first thing I do is check whether the file is indeed the one I want, then I sort the data according to the 4th column, and then I need to manually order the sorted line.
For example, I need to print the 3rd word in the line, and then the first word etc.
Here is what I wrote:
mainScript :
for file in `ls ${1}` ; do
if [[ ! ($file = *.user) ]] ; then
sort -nrk4 $file | source printer_script
printer_script :
echo $3
echo $1
echo $2
Why nothing gets printed even though I send the sorted lines by pipeline?
