The present invention comprises a flat panel display, such as a liquid crystal microdisplay having a plurality of square and rectangular pixel electrodes that are addressable separately to produce a fine resolution display or addressable in combination to create a lower resolution display. By providing an array of square pixel electrodes with adjacent rectangular electrodes, the display is capable of displaying, for example, XGA or SXGA video data, full-size undistorted and in its native display format, thus obviating the need for expensive image processing chips to convert the image data from one format to another.

Reconfigurable microdisplay

A double integrating silicon acceleration sensing device which is solid state and micromachined measures the acceleration of an object and determines the distance travelled by that object through its trajectory. The device comprises a hermetically sealed container. The cavity within the container is divided by a flexible silicon diaphragm into two separate cavities, one shallow and the other deep. The two cavities are filled with a fluid which is relatively incompressible over the range of operating pressure. The fluid can only transfer between the two cavities through an orifice. Two capacitor plates form a capacitor within the shallow cavity. One of the plates is secured to a central portion of the diaphragm, and the other plate is secured adjacent to and opposite of the first plate within the shallow cavity. When the accelerometer is at rest, the two plates are separated by a given distance X.sub.g. When the accelerometer experiences an acceleration, the diaphragm deflects into the deep cavity forcing fluid from the deep cavity into the shallow cavity. The gap between the two capacitor plates X.sub.g increases causing a change in the total capacitance. This capacitance value is exactly proportional to the distance travelled by the object for constant acceleration, and is approximately proportional to the distance travelled for other acceleration pulses. When capacitor plates are coupled adjacent and opposite each other in the deep cavity, in addition to capacitor plates in the shallow cavity, a differential capacitance results.

Double-integrating silicon acceleration sensing device

A projectile having a piercing front end with a solid lubricant molded on the front surface for reducing friction during penetration. The lubricant is molded in a shape to receive an antenna and other electronics. The front end also has an axial hole formed therein to enhance self destruction from the sudden release of compressional strain energy accumulated during penetration through a hard target.

Penetrating projectile

This is a method for an adaptive delay time after impact of a projectile by determining the spin rate of the projectile using spin switches to set a time delay which may then be updated using a time of flight counter. This method may be used on artillery shells of varying calibers and each caliber of which has varying velocities.

Fuze actuating method having an adaptive time delay

A safety and arming mechanism wherein a sliding member is held in an out-of-line position breaking the fuze train. An actuator releases the sliding member and moves the sliding member, which contains a stab detonator, in-line and towards a firing pin completing the fuze train. Arming and detonating occur at the same time when the fuze train is completed and the stab detonator is impaled on the firing pin.

Electro-explosive safety and arming device

The present invention consists of an apparatus for damping the movement of a microbeam sensor. The damping device consists of a gold plated chrome bar, or the like being placed, or fabricated, above the microbeam. This damper prevents excessive movement that could be caused from harmonic vibrations or the like.
