Abstract: A tire pressure monitoring system where the position and orientation of a receiver antenna associated with the tire pressure monitoring system is at a location that is proximate the tire pressure monitoring system. In one embodiment, the receiver antenna is positioned beneath a vehicle chassis. The location of the receiver antenna can be determined by system performance prediction tools that include mean-time-to-warning verses packet error rate curves for a desired packet error rate and packet error rate verses signal-to-noise ratio curves for various operational scenarios and different classes of vehicle that provides a necessary signal-to-noise ratio for a wireless link, and operational scenarios that established desired levels of performance and reliability.

Abstract: 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.

Abstract: The radiation properties and wave guiding properties of frequency selective surfaces are used in conjunction with closely spaced antenna elements to fabricate antenna structures having adjustable radiation characteristics. The direction, magnitude, and polarization of radiation patterns for such antenna structures can be adjusted by varying the texture or patterning of layers of conducting material forming the frequency selective surfaces. The invention enables the fabrication of low profile antenna structures that can easily be conformed or integrated into complex surfaces without sacrificing antenna performance.

Abstract: 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.

Abstract: 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.

Abstract: A long-range optical fiber communication link overcoming certain constraints on signal transmission range imposed by fiber-induced loss is disclosed herein. A first embodiment of the communication link (10) of the present invention includes an optical fiber (16) having a first and a second end wherein the attenuation of optical energy passing therethrough at wavelengths included within a transmission window is substantially minimized. The inventive link (10) further includes a first arrangement (22) and (36) for launching a first optical carrier of a first wavelength onto the first end of the fiber (16). Provision is made within the launching arrangement (22) and (36) for impressing a first modulating signal spanning a first frequency spectrum upon the first carrier. The first embodiment also includes a second arrangement (26) and (37) for launching a second optical carrier of a second wavelength onto the second end of the fiber, wherein the second wavelength is included within the transmission window. The second launching arrangement (26) and (37) is further disposed to impress upon the second carrier a second modulating signal spanning a second frequency spectrum segregated from the first spectrum. A first receiver (64) of a first bandwidth encompassing the first frequency spectrum is coupled to the second end of the fiber (16). The first receiver (64) is operative to extract the first modulating signal from the first optical carrier. A second receiver (58) having a second bandwidth encompassing the second frequency spectrum is coupled to the first end of the fiber (16).
