Abstract: A radar system includes a radio frequency (RF) section that is controllable to focus operation in one of a plurality of fields of view (FOVs) and a control section configured to identify a side of the vehicle in which the radar system is installed and direct the RF section to focus transmission and reception in one of a first or a second FOV based on the side of the side of the vehicle in which the radar system is installed. A method includes: transmitting RF energy and listening for a reflection from a predetermined target mounted on one side of a vehicle; determining a whether a reflection has been detected; and directing the RF section to focus operations to the FOV that is predetermined for use for a radar system mounted on a same side of the vehicle as the predetermined target when a reflection has been detected.

Abstract: A rain sensor in a vehicle includes a transmitter to implement a pseudorandom modulation of a timing of emission of infrared transmissions toward a windshield of the vehicle. The rain sensor also includes a receiver to be active for only a specified period of time following each emission of the infrared transmissions and to receive a reflection based on the infrared transmission encountering any substance on the windshield.

Abstract: A method for controlling a rear glass defroster for a vehicle upon start-up is presented. First, one or more factors are determined, which are selected from a temperature of an environment immediately outside the vehicle, a humidity of the environment, a dew point of the environment, a barometric pressure of the environment, a temperature of a rear glass of the vehicle, a temperature of an internal cabin of the vehicle and a sun load on the vehicle. Next, the one or more factors are compared to one or more corresponding predetermined thresholds or ranges that are indicative of conditions suitable for frost formation on a rear glass of the vehicle. Then, if the comparison indicates that the one or more factors meet the frost formation conditions, the rear glass defroster is activated. A vehicle rear-glass defrost system which uses the foregoing method is also presented.

Abstract: In an example of a method for performing vehicle antenna diagnostics, a transmitting and receiving (TX/RX) antenna of a multiple input multiple output (MIMO) antenna assembly of a vehicle is electronically caused to emit a check signal. A response of a receiving only (RX) antenna of the MIMO antenna assembly is electronically detected in response to the check signal. A received signal strength indictor output is generated in response to the response of the RX antenna. The received signal strength indictor output is converted to a digital signal. The integrity of the MIMO antenna is determined after comparing the digital signal with an expected power level of the RX antenna.

Abstract: A method and apparatus that determine whether an occupant of a seat is operating a touch screen. The method includes detecting a signal received through an antenna embedded in a seat, determining whether the detected signal is generated by an input to a touch screen, and outputting information indicating an occupant of the seat is operating the touch screen if the determining determines that the detected signal is generated by an input to a touch screen.
