摘要： A timer for measuring a time lapsed during an acceleration is disclosed. The timer may include a piezoelectric sensor, an energy storage device and a measurement module. The piezoelectric sensor includes a piezoelectric material for generating an electric potential in response to the acceleration. The energy storage device is electrically coupled to the piezoelectric sensor and is configured for receiving the electric potential generated by the piezoelectric sensor. The measurement module is electrically coupled to the energy storage device. The measurement module measures the electric potential received at the energy storage device and determines the time lapsed during the acceleration based on the electric potential received at the energy storage device.

摘要： An Electronically Scanned Array (ESA) antenna is controlled via an optical domain without electrical conductors on the ESA Printed Wiring Board (PWB). Distribution of the control signal occurs over pulses of light through an optical medium separate from the ESA PWB. External to the ESA PWB are one or more optical wave guides functional as communications channels which connect the ESA optical receivers/transceivers with transmitters/transceivers interfaced to a system controller. The ESA is divided into groups of elements with serial busses and discrete signals driven by local controllers. The local controller for each group of elements may include one or more optical receivers (unidirectional) or transceivers (bidirectional). This concept offers a trade in electrical complexity associated with an ESA PWB for an additional manufactured medium redundantly supplying the control signal to the ESA as well as routing the RF data signal from the ESA to the system controller.

摘要： The present invention is a method for capturing a cooling transfer function for a thermally-isolated, self-heating device. The method includes causing the device to undergo a plurality of successive heat-up cycles and cool-down cycles. The method further includes changing durations of time of the successive cool-down cycles. The method further includes deducing the cooling transfer function based upon temperature measurements for the device obtained at the end of the successive cool-down cycles (ex.—at the beginning of the successive heat-up cycles) of the device. The method thereby allows for capture of the cooling transfer function without direct observation of the cooling transfer function.

摘要： High efficiency transmitters for electronically scanned arrays (also known as electronically steered antennas or ESAs) are disclosed. The transmitters in accordance with the present disclosure utilize outphasing power amplification. In one embodiment, the outphasing transmitter includes a phase shifting device. The phase shifting device is configured for phase shifting an input signal and providing a pair of phase shifted signals for each emitting element of the EAS. The outphasing transmitter also includes an outphasing power amplifier associated with each emitting element. Each outphasing power amplifier is configured for separately amplifying the pair of shifted signals for each emitting element and combining the separately amplified signals for each emitting element for transmission.

摘要： The present invention is directed to a piezo-electrically actuated membrane (ex.—a tuner) configured for use with a tunable cavity filter. The piezo-electrically actuated tuner may be formed of printed circuit board materials and may be placed over the cavities of the tunable cavity filter. Further, the piezo-electrically actuated tuner may promote high level performance of the tunable cavity filter, while allowing the tunable cavity filter to be tunable across wide bands.

摘要： An etching based semiconductor wafer thinning arrangement usable as an improved alternative to the usual grinding and polishing wafer thinning. The thinned wafer includes a structurally enhancing wafer backside grid array of original wafer thickness semiconductor material with grid cells surrounding individual thinned wafer areas and serving to improve the strength and physical rigidity characteristics of the thinned wafer. Preferably this grid array is supplemented with an additional, wafer periphery-located, backside ring of semiconductor material also of original wafer thickness. Ability to avoid a wafer front side mounting during thinning accomplishment, fast etching, reduced wafer breakage, enhanced wafer strength and improved wafer handling achieved with the disclosed thinning arrangement all contribute to achieved advantages over conventional wafer thinning. Gallium arsenide or other semiconductor materials are contemplated along with use in radio frequency or other integrated circuit devices of either the single transistor or complete integrated circuit components types.
