摘要： The RF/microwave switch/modulator uses an optically controlled diode 20. The reactance of the diode may be varied by varying the illumination intensity. In this fashion, the photodiode in conjunction with an external circuit can switch or modulate a microwave signal by varying the reactance of the diode using a laser light source or the like. The bias voltage may be varied to electronically tune the diode so that the microwave frequency of operation can be electronically controlled.

摘要： The optical receiver has a photodiode (10) which is reverse biased by a voltage supply (14). The voltage supply provides a variable bias voltage determined by a control unit (16) and the photodiode is matched to the load (22) by an impedance matching circuit (12). The photodiode exhibits large capacitance changes over a range of bias voltages and may be implemented using a Schottky barrier or P.sup.+ N photodiode. By changing the bias voltage, the photodiode capacitance changes to vary the tuned frequency of the receiver. The matching circuit cancels the reactive component of the photodiode impedance and matches the resistive component to the load. The photodiode may have a doping profile in which an intrinsic or lightly doped region of width greater than the average photon penetration depth is located next to the junction. After the intrinsic region, the doping profile may be selected to achieve linear tuning. This doping profile gives linear tuning without sacrificing photodiode conversion efficiency.

摘要： The corporate feed network employs light emitting opto-electronic components, such as laser diodes (12), connected together in a string (14) for distributing RF, microwave, MMW, digital signals, and pulse modulated light. Each diode provides two ports or facets which are coupled to optical fibers (16, 18) to connect to an active phased array antenna, for example. The diodes are selected in number and impedance to provide a good wideband impedance match to the RF/microwave/MMW/digital driving source. Multiple series strings of diodes may be employed, connected in parallel for larger corporate feed structures.

摘要： There is provided an exemplary tire pressure monitoring (TPM) system that can use a half-duplex wireless link to communicate between one or more wheel-mounted sensor units and a vehicle-mounted transceiver unit. The half-duplex wireless link enables the sensor units to report sensor readings to the transceiver unit, and it enables the transceiver unit to make configuration changes to the sensor units for improved communication. Some examples of wireless settings that can be modified include modulation settings, data encoding/decoding settings, error correction settings, and transmission power settings.

摘要： To facilitate GPS hardware selection and evaluate performance of vehicle integrated GPS hardware, including various types of GPS antennas and receivers, within different vehicle operating environments, embodiments of the invention are used to provide a simulator which does not require physical GPS hardware to simulate GPS system performance. Preferably, the simulator randomly generates one or more GPS system link budget variables, within predetermined performance bounds, in order to predict GPS system performance in a specific vehicle operating environment for a given antenna radiation pattern and/or GPS receiver. The simulator employs a Monte Carlo technique to evaluate the GPS system performance based on generated pools of link budget variables.
