Abstract: This invention discloses a multiple quantum well infrared detector comprising a series of alternating layers of blocking layers and composite well layers. Each composite well layer is comprised of alternating layers of GaAs and AlGaAs forming a tightly coupled well group. The tightly coupled well group allows more allowed states for an electron released from the valence bands of the gallium arsenide semiconductor material. Consequently, there is a wider band width of detectable infrared radiation by the composite wall structure over the single well of the prior art.

Abstract: A fast Fourier transform circuit formed on a single chip, including a fast multiplier-accumulator circuit which, in the preferred embodiment, employs a modified form of Booth's algorithm, an adder circuit, a read-only memory for storing FFT twiddle factors, and a random access memory for holding a set of input complex quantities and for receiving intermediate and final results in an in-place FFT operation. In the preferred embodiment, the FFT twiddle factors are stored in Booth's code for greater speed of operation. Control and timing circuitry on the same chip generates control signals and address codes in order to perform a sequence of butterfly computations by repeated use of the multiplier-accumulator and adder circuits, to generate FFT coefficients in the random access memory.

Abstract: A vehicle occupant airbag deployment system (50) that detects, identifies and tracks a person (16) in the passenger seat (18) of a vehicle (12), and provides a signal for no fire, soft fire or hard fire of the airbag (20) depending on the location of the person (16) in a crash event. The airbag deployment system (50) employs infrared emitters (30) that emit an infrared signal towards the passenger seat (18) of the vehicle (12) and an infrared detector (34) that receive reflected radiation from objects in the seat (18). Processing circuitry (52), including face recognition software, is employed to detect human face features to provide the necessary detection and tracking of the person (16). In this manner, the system (50) prevents the airbag (20) from firing if the seat (18) is not occupied by a person (16), prevents the airbag (20) from firing if a person (16) is detected, but is too close to the airbag (20), and provides a soft fire if a person (16) is detected, but is within a soft fire range of the airbag (20).

Abstract: A system and method for monitoring tread wear, shock absorber performance, balance condition of a vehicle tire, and/or rotation speed of a vehicle wheel, use a sensor to provide acceleration signals. To monitor tread wear, acceleration signals from the sensor determine at least one resonance frequency of at least one of the radial and lateral acceleration of the tire and compares it to at least one stored resonance frequency To monitor shock absorber performance, the amplitude of the Fourier component of the radial acceleration is compared to a stored amplitude value. To monitor a balance condition of a vehicle tire, the sensor provides acceleration signals measured over a specified time duration to determine an amplitude of the Fourier component of the radial acceleration that is compared to a stored amplitude specification balance condition of the tire.

Abstract: This invention discloses an infrared detector which separates current induced by incident gamma ray radiation for use in a radiation environment. The infrared detector includes a semiconductor which includes a first layer heavily doped with n-type atoms, a second undoped layer and a third layer lightly doped with n-type atoms. At least one heavily doped n-type contact region and one heavily doped p-type contact region are embedded in the third layer. Both incident gamma ray photons and infrared photons release charge carriers in the second layer which travel as conduction current through the semiconductor. Since gamma rays are of high energy, they can release electrons from the valence band into the conduction band. When an electron is released from the valence band a hole is generated in its place which acts as current charge carrier. The electron released into the conduction band travels to the first layer and the hole travels to the p-type contact region under the influence of an electric field. An infrared photon, however, will only have enough energy to release an electron in the impurity band of the second layer to the conduction band. Therefore, there is no hole current collected at the p-type contact regions. When an electron is released from the impurity band, an electron from the n-type contact region replaces this electron. Consequently, current induced by gamma and infrared radiation can be separated.

Abstract: A field-effect transistor in which the gate and source are positioned on opposite faces of a substrate, and a method for its fabrication. In the method, a stop-etch buffer layer and an active semiconductor layer are successively formed by molecular beam epitaxy on a first face of a substrate of semi-insulating material, such as gallium arsenide. A source via hole is etched from the opposite face of the substrate, using a first etchant that does not react with the buffer layer, and extended through the buffer layer with a second etchant that does not react with the active layer. After metalization of the source via hole, electron beam lithography techniques are used to determine its location as viewed from the first face of the substrate. Then a mesa area is formed from the active layer, and drain and gate areas are defined in precise relation to the source via hole, and are metalized.

Abstract: A tire monitoring method and apparatus is provided to predict tire tread separation for a tire on a wheel of a vehicle. This may involve monitoring a parameter of a tire of a vehicle over time and comparing information regarding the monitored parameter (over time) with a reference threshold value of the parameter (over time). The method may also include providing information to a driver based on the comparison. The parameter may be acceleration (axial, radial or longitudinal) along an axis of the tire. The parameter may also be tire imbalance, temperature inside the tire, speed of the tire, load and/or pressure, for example. Information regarding the comparison may be transmitted to a driver if the monitored parameter exceeds the reference threshold value for a predetermined amount of time.
