摘要： Techniques for charger-device pairing for recharge warnings are described. In one or more implementations, a battery (108) of a device (102) is determined to require charging based on a state of charge of the battery (108). In response to this determination, a message is communicated via a local network (106) from the device to a charger (104) that was previously paired with the device (102). The message includes a request for the charger (104) to generate a first alert indicating that the charger is available to charge the battery of the device. In addition, the device (102) provides a second alert indicating that the battery (108) of the device requires charging.

摘要： Embodiments include devices and methods for navigating an unmanned autonomous vehicle (UAV) based on a measured magnetic field vector and strength of a magnetic field emanated from a charging station. A processor of the UAV may navigate to the charging station using the magnetic field vector and strength. The processor may determine whether the UAV is substantially aligned with the charging station, and the processor may maneuver the UAV to approach the charging station using the magnetic field vector and strength in response to determining that the UAV is substantially aligned with the charging station. Maneuvering the UAV to approach the charging station using the magnetic field vector and strength may involve descending to a center of the charging station. The UAV may follow a specified route to and/or away from the charging station using the magnetic field vector and strength.
