摘要： A system and method for obtaining a Doppler frequency of a target are disclosed. A receiver receives a first plurality of samples of a first echo signal from the target and a second plurality of samples of a second echo signal from the target. The second plurality of samples is separated from the first plurality of samples by a time period. A phase shift is determined for the duration of the time period and the phase shift is applied to the second plurality of samples. The first plurality of samples is combined with the second plurality of samples to obtain combined samples, and the Doppler frequency for the target is obtained from the combined samples.

摘要： A method and system for selectively providing cellular offload services to mobile user data devices via vehicle-based access points. Subscribers and affiliates of vehicle-related online services register their user data devices for authorized connections. Vehicle metrics are used to determine the state of a vehicle (being driven or parked), and the metrics of the user device can be compared with the vehicle metrics to determine if the user device is inside the vehicle. Limiting access to authorized user devices reduces load on the vehicular access points and allows preventing the vehicular access points from being erroneously included on access point maps and thereby infecting the maps.

摘要： A TPMS that uses a unique signature, such as RSSI signal levels and statistics or Doppler shift information, to identify the location of where the TPMS signal is being transmitted from. The TPMS includes a separate transmitter unit provided in each tire, where each transmitter unit transmits TPMS signals including an ID code identifying the tire and the pressure in the tire. The TPMS also includes a receiver unit that receives the TPMS signals from each of the transmitter units, where the receiver unit stores an average or other classification of the signature over time to identify the location of the transmitter unit for a particular ID code. The receiver unit compares the new received TPMS signals to the classified signals to identify whether the ID code indicates that the position of the tire has changed.

摘要： A radar system and method of extending a parameter of a location of a target obtained by radar is disclosed. The system receives an echo signal that is a reflection of a radar source signal from the target. The echo signal is sampled and a peak for the echo signal is objected in frequency space. For a peak that is located at a frequency greater than a Nyquist frequency of the echo signal, the peak is moved to a negative domain of the frequency space and the location of the target is determined using the peak in the negative domain.

摘要： Slot antennas built into metallic body panels utilize the vehicle body itself as an antenna radiator. Building the slot antennas directly into the metallic body panels converts the vehicle body from functioning as an RF shield into an RF antenna, which significantly improves mobile communication reception for a wide range of RF communication devices. Different types of slot antennas may be included for different communication channels utilized by different types of devices. Multi-band slot antennas are configured to receive multiple bands within a larger frequency channel. Dual-polarity antennas are configured to receive signals propagating in a dual-polarity mode. Multiple slot components may be configured as multi-band, dual-polarity antennas. Each slot antenna may be passive (without an RF pickup) or active with an RF pickup and coaxial cable connecting the antenna to an electronic device, such as receiver or amplifier located inside or otherwise interconnected with the vehicle.

摘要： A system for providing power signals to peripheral devices on a vehicle using magnetic resonance coupling. The system includes a transmitter circuit having a variable current source, a base coil and a variable capacitor, where the current source and the capacitor are tuned to provide a predetermined AC current to the base coil so as to generate an oscillating magnetic field at a predetermined frequency. The system also includes a receiver circuit for each peripheral device, where each receiver circuit includes a receiver coil and a rechargeable power source. When the base coil is tuned to the receiver coil the power source can be recharged through magnetic resonance coupling to power the device. The transmitter circuit can be on the vehicle or can be separate from the vehicle, such as in a charging pad.

摘要： A system and method for wirelessly controlling a shape memory alloy (SMA) actuator using magnetic resonant coupling (MRC). The SMA actuator is part of a receiver circuit including an actuator coil, where the SMA actuator is configured into a certain shape. The system includes a transmitter circuit having a transmitter coil and a controller, where the transmitter coil receives an AC current that causes the transmitter coil to generate an oscillating magnetic field in resonance with the actuator coil in the receiver circuit and be magnetically coupled thereto. The current induced in the actuator coil creates heat that reconfigures the SMA actuator to provide the actuation.

摘要： Methods and systems are provided for receiving desired sounds. The system includes a position sensor configured to determine an occupant position of an occupant engaging in speech within a defined space and transmit the speaking occupant position. A plurality of microphones are configured to receive sound from within the defined space and transmit audio signals corresponding to the received sound. A processor, in communication with the position sensor and the microphones, is configured to receive the speaking occupant position and the audio signals, apply a beamformer to the audio signals to direct a microphone beam toward the occupant position, and generate a beamformer output signal.
