Abstract: A motion compensated integration system and process for scanning a field and producing images of one or more densely filled wavebands has a moveable platform, an optical sensor, and optical sensor line-of-sight measuring device, and a processor. The optical sensor is mounted to the moveable platform and is made up of a telescope that is in functional relationship with a focal plane array. The focal plane array comprises one or more sets of detectors capable of receiving one or more wavebands and producing focal plane array data of the wavebands, respectively. The optical sensor line-of-sight measuring device is capable of producing optical sensor line-of-sight movement data. The processor is capable of receiving the focal plane array data and the optical sensor line-of-sight movement data and producing output images representing the wavebands, respectively. The system and process may normalize the data to account for border regions of the stabilized arrays.

Abstract: An inventory management system which includes a transponder, an interrogation transceiver and control devices utilized therewith. The control devices operate to minimize the power consumption of the transponder while permitting selected, coded operation of the inventory management system. The interrogation transceiver provides linkage to the transponder by means of a modulated radio frequency (RF) carrier during system operation. A transmit/receive switch is also included in the invention to prevent harmful coupling between the transponder receiver and the transponder transmitter. This could occur during data exchanges between the transponder and the interrogation receiver.

Abstract: A simulator and method of testing a sensor wherein an electron gun mounted n a vacuum chamber directs a stream of electronic onto a target plate made up of a heat sink backing sheet and a heat insulating coating sheet adhered to the backing layer to form small hot spots on the coating sheet. The target plate may be a sheet of copper to which is adhered a coating layer of glass or a sheet of aluminum to which is adhered a coating layer of aluminum oxide. Infrared radiation from the hot spots is collimated and passed through an optical system which forms an image of the hot spots on the sensor to be tested.

Abstract: Electronic countermeasure technique for protecting low-flying aircraft from radiant energy guided missiles by bouncing a decoy guidance signal off the ground near the aircraft.

Abstract: An inventory management system establishes remote, non-contact counting techniques whereby large numbers of units in inventory can be tracked and tabulated quickly. The system includes microelectronic transponders associated with inventory units. The transponders can communicate with computer controllers and automated data processing over standard telephone lines by using typical telemetry or other communication systems.

Abstract: A microprocessor based apparatus for use as a bus controller and as a remote terminal in a time-division multiplex serial data bus system. The apparatus comprises a single chip which, in a preferred embodiment, is in the form of radiation hardened LSI/CMOS/SOS. It operates on a one bit per instruction basis and includes program control of output signals and word length. The described embodiment is program adapted to satisfy the performance requirements of the applicable military standard, but is easily modified, by changing the contents of an external expandable instruction storage device, to accommodate alternative requirements such as different word lengths, different message formats, and even different bus protocols. A data format encoder and data format decoder provide means to convert from Manchester bi-phase data to NRZ data for receiving data from the data bus and to make the opposite conversion for transmitting data over the data bus.

Abstract: An intensity control system for a cathode ray tube (CRT) is disclosed. The system provides precise intensity control for a CRT whose control characteristics are only slowly varying. Precise intensity control is provided by measuring the cathode ray tube beam current. The beam current is set at a desired value without producing an image on the tube face. Thus, tube intensity can be set without fogging photoresponsive media which is in position for exposure by images on the cathode ray tube screen. The intensity may be set to a value determined by a manually adjustable intensity control. The intensity is preferably set by iterative threshold comparison of the actual beam current with the value corresponding to the setting of the intensity control. A unique threshold comparison circuit provides precise comparison between the reference level set by the intensity control and the actual beam current.

Abstract: A digital character generator method and system encode characters based on a normalized quad in accordance with coordinates of initial starting points of outlines of the character and variational parameters defining changes in those outlines such as slope and curvature. All characters of all formats are encoded for a maximum point size display. Vertical scaling factors permit character generation at any desired point size display. Horizontal scaling factors are employed both for transforming computations based on the encoded parameters for the normalized quad to a desired point size of display and also to adapt cyclic computations to the stroking density of a display CRT.
