摘要： A system, circuit and methods for target detection from hyper-spectral image data are disclosed. Filter coefficients are determined using a modified constrained energy minimization (CEM) method. The modified CEM method can operate on a circuit operable to perform constrained linear programming optimization. A filter comprising the filter coefficients is applied to a plurality of pixels of the hyper-spectral image data to form CEM values for the pixels, and one or more target pixels are identified from the CEM values. The process may be repeated to enhance target recognition by using filter coefficients determined by excluding the identified target pixels from the hyper-spectral image data.

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： A fault-tolerant architecture, comprising fault tolerant units, a wire-based communication bus, and respective radio transceivers is offered. The fault-tolerant units communicate using the radio transceivers when communication via the wire-based communication bus is compromised by a fault. The intent is to enhance reliability and fault-tolerance of a distributed system architecture, such as a steer-by-wire system for a vehicle. The novel drive-by-wire/wireless architecture uses multiple wireless sensors and short-range low power radio transceivers associated with various micro-controllers. These sensors and radio transceivers allow the micro-controllers to communicate critical control signals and drive commands in the event of a communications fault, e.g. in a vehicle drive-by-wire system.

摘要： 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.
