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

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for a voltage controlled charge pump and battery charger. Certain aspects of the present disclosure provide a method for operating a voltage controlled charge pump. The method includes selectively opening and closing a plurality of switches based on a voltage on a feedback path. The plurality of switches are coupled between a voltage input terminal and a voltage output terminal. A first capacitor is coupled between at least a first switch and a second switch of the plurality of switches. A second capacitor is coupled to the voltage output terminal. The feedback path is coupled to at least one of the voltage output terminal, the first capacitor, and the second capacitor.

Abstract: 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.

Abstract: Aspects of the present disclosure generally relate to multi-mode regulators. For example, the multi-mode regulator may include a first transistor having a first terminal coupled to an input voltage and a second terminal coupled to an output of the regulator, a second transistor having a first terminal coupled to the second terminal of the first transistor and a second terminal coupled to a reference potential, pulse width modulation (PWM) control logic having outputs coupled to gates of a first transistor and a second transistor, one or more error amplifiers, and a switch with a first terminal coupled to the gate of the first transistor and a second terminal coupled to the output of one of the one or more error amplifiers. By selectively configuring one or more components of the multi-mode regulator, the regulator may operate according to either a linear regulation mode or a switching regulation mode.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for limiting the power drawn by a battery charger based on monitoring of the input voltage and input current supplied to the battery charger from a power supply. In certain aspects, a method generally includes sensing an output voltage of the power supply, wherein the output voltage of the power supply is variable. The method further includes sensing an output current of the power supply. The method further includes providing the output voltage and output current to a battery charger. The method further includes generating a control signal indicative of a scaling of the output current based on a scaling factor, wherein the scaling factor is based on the output voltage. The method further includes providing the control signal to the battery charger to control the output current supplied by the power supply to the battery charger.
