Abstract: Methods and devices are provided for allowing a mobile device (e.g., a key fob or a consumer electronic device, such as a mobile phone, watch, or other wearable device) to interact with a vehicle such that a location of the mobile device can be determined by the vehicle, thereby enabling certain functionality of the vehicle. A device may include both RF antenna(s) and magnetic antenna(s) for determining a location of a mobile device relative to the vehicle. Such a hybrid approach can provide various advantages. Existing magnetic coils on a mobile device (e.g., for charging or communication) may be re-used for distance measurements that are supplemented by the RF measurements. Any device antenna may provide measurements to a machine learning model that determines a region in which the mobile device resides, based on training measurements in the regions.

Abstract: A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.

Abstract: Systems, methods, and devices for grouping client devices based on sensor data in an assisted wireless communication system are provided. Sensor data may include device mobility, device type, and device application data usage, among other characteristics. An assisted wireless communication system may include client devices sending data to an access point. The clients may send conventional protocol data over a channel and, concurrently, send sensor data over an alternative channel. In some cases, client devices may exchange their protocol data, modify their own protocol data based on the exchanged data, and send the modified protocol data to the access point. This may allow the clients to adjust their grouping.

Abstract: A wireless power transmission system may include a wireless power transmitting device such as a tablet computer and a wireless power receiving device such as a computer stylus. A wireless power transmitting capacitor electrode may be formed in the tablet computer. A wireless power receiving capacitor electrode may be formed in the computer stylus. The transmitting capacitor electrode may be driven by a drive signal having a frequency of 900 MHz or greater to produce wireless power. The wireless power may be transmitted from the transmitting capacitor electrode to the receiving capacitor electrode on the stylus via near field capacitive coupling. The transmitting and receiving capacitor electrodes may each include conductive traces on dielectric substrates. The conductive traces may follow meandering paths to maximize the possible capacitive coupling efficiency between the capacitor electrodes and thus the end-to-end charging efficiency of the wireless power transmission system.
