Abstract: Systems and methods for vehicle microphone activation and/or identification of incoming speech-to-text data by the location of the speaking occupant. In some embodiments, the system may comprise a plurality of microphones, each of which may be linked with a particular occupant/seat in the vehicle. The system may be configured to link incoming STT data with a particular microphone/occupant. This may be done by an explicit trigger from an occupant or by actuation of a button or other actuation means by a vehicle occupant. The STT data may then be processed using the location data.

Abstract: A radar system and method include a first transmitted radar signal having a first frequency and a second transmitted radar signal having a second frequency different from the first frequency. A receiver receives reflected radar signals generated by reflection of the transmitted radar signals and generates receive signals indicative of the reflected radar signals, a first receive signal being indicative of a first reflected radar signal generated by reflection of the first transmitted radar signal, and a second receive signal being indicative of a second reflected radar signal generated by reflection of the second transmitted radar signal. A processor receives the first and second receive signals and computes a difference between the first and second receive signals to generate a difference signal, the processor processing the difference signal to provide radar information.
