Abstract: A system and method to mitigate electromagnetic interference generated by a source resonator of a wireless charging system is presented. The system includes a receiver that configured to receive a wireless charging signal transmitted by the source resonator, a phase shifter in communication with the receiver and configured to generate a canceling signal that is 180° out of phase with the wireless charging signal currently received by the receiver, and a transmitter in communication with the phase shifter and configured to electromagnetically transmit the canceling signal, thereby canceling at least a portion of the wireless charging signal. The canceling signal being at the same frequency and 180° out of phase interferes with the charging signal to reduce or eliminate electromagnetic interference in the vicinity of the vehicle being charged.

Abstract: A safety system and a method configured to determine whether a passenger compartment of a vehicle is occupied whether the temperature of the passenger compartment is outside an acceptable temperature range, and to take a safety countermeasure if needed. An occupant is detected by sounds received by an audio transducer within the passenger compartment connected to an infotainment system. The temperature is detected by a temperature sensor connected to the heating, ventilation and air condition system of the vehicle. Example safety countermeasures include activating the horn, transmitting a wireless signal indicating that an unattended occupant is in the vehicle to a remote wireless receiver, and/or at least partially opening a vehicle window. A pair of high frequency speakers connected to the infotainment system may be used to transmit and receive ultrasonic signals so that an occupant may be detected using ultrasonic motion detection techniques.
