摘要： A heterojunction bipolar transistor is doped in the sub-collector layer (20) with phosphorus (24). The presence of the phosphorus causes any interstitial gallium (22) to be bonded (26) to the phosphorus (24) and move to a lattice site. The result is that the interstitial gallium does not diffuse to the base layer and thus does not cause the beryllium to be displaced and diffused. Instead of doping with phosphorus, a layer including phosphorus can also be utilized.

摘要： A method of manufacturing a HEMT IC using a citric acid etchant. In order that gates of different sizes may be formed with a single etching step, a citric acid etchant is used which includes potassium citrate, citric acid and hydrogen peroxide. The wafer is first spin coated with a photoresist which is then patterned by optical lithography. The wafer is dipped in the etchant to etch the exposed semiconductor material. Metal electrodes are evaporated onto the wafer and the remaining photoresist is removed with solvent.

摘要： The reflective mesh material that forms the reflector in a foldable perimeter truss antenna is remotely adjusted to shape using remotely controlled stepper motors carried on the truss. Connected to the end of the catenaries, which shape and support the pliant reflective mesh material on the truss, the stepper motors adjust the tension on the catenaries and thereby change its shape. An RF receiver and electronic controller associated with each stepper motor receives the tension command information from a remote source and controls the stepper motor in accordance with that information.

摘要： A transceiver-processor building block (700) for implementation of radio systems, an example being used in an electronic radio system multifunction slice, includes several transceivers (704-710), a processor connected to the transceivers (702), and a local RF control bus (726) coupled between the processor (702) and the transceivers (704-710). A radio network bus (716) is also provided and connected to the processor (702). The local RF control bus (726) is inaccessible directly from outside the multifunction slice. In contrast, the radio network bus (716) is accessible directly from outside the multifunction slice to allow "stacking" of multiple slices. The building block (700) may also include an external control bus (728) connected to the processor (702). An external control bus connector (730) then provides direct accessibility to the external control bus (728) from outside the multifunction slice.

摘要： This disclosure describes an electronic support measures (ESM) system for estimating the angle of arrival of a signal which impinges on an array of antennas configured in a straight line. The antennas in the array are spaced such that the distances from the interior antennas to one of the end antennas--in terms of units of a reference length ξ-are relatively prime. The system does not require a priori knowledge of the signal radio frequency. In order to enhance the computational efficiency and ability of the system, a Diophantine processing algorithm is utilized. The set of antenna spacings is selected based upon minimizing the probability that this algorithm produces an ambiguity error in the estimated angle of arrival. The computational efficiency of the system is improved relative to current systems, as it requires only N 2 real multiplications, where N+1 is the number of antennas in the array. The required N 2 real multiplications can be realized in non-interacting pipelined parallel paths, leading to reduced latency of angle estimation. As such, the ESM system in accordance with the present invention is adapted to be used in various avionics applications that were heretofore beyond the computational processing ability of known systems.

摘要： A laser-plasma EUV radiation source (50) that generates larger liquid droplets (72) for the plasma target material. The EUV source (50) forces a liquid (58), preferably Xenon, through a nozzle (64), instead of forcing a gas through the nozzle. The geometry of the nozzle (64) and the pressure of the liquid (58) through the nozzle (54) atomizes the liquid (58) to form a dense spray (70) of droplets (72). Because the droplets (72) are formed from a liquid, they are larger in size, and are more conducive to generating EUV radiation. A condenser (60) is used to convert gaseous Xenon (54) to the liquid (58) prior to being forced through the nozzle (64).

摘要： A system for providing recognition of an acoustic wave generated within an interior cabin of an automobile includes an anchored strap placed across the chest of a passenger seated in the automobile and a low power, high fidelity wireless microphone unit integrated with the anchored strap at a position substantially proximal to the passenger's chest. The microphone unit detects the acoustic wave within the interior cabin of the automobile, generates a frequency modulated signal corresponding thereto and transmits the frequency modulated signal to a receiver unit that is also located within the interior compartment of the automobile.

摘要： A voice-activated microphone and transceiver system includes an interrogator unit for transmitting a signal, receiving a modulated signal, and demodulating the modulated signal such that the difference between the transmitted signal and the modulated signal correspond to a unique sound wave signal. An acoustically driven microphone unit is also included for receiving the signal from the interrogator unit, modulating the signal with the sound wave signal, wherein the sound wave signal contains instructions for controlling an electronic device, and transmitting the modulated signal back to the interrogator unit for analysis by a signal processor.
