Abstract: A wireless electronic device with a kinetic-energy-to-electrical-energy converter is disclosed. In one embodiment, the wireless electronic device comprises a control mechanism, a kinetic-energy-to-electrical-energy converter, and a movable user interface element, wherein movement of the movable user interface element provides both signal information to the control mechanism and kinetic energy to the kinetic-energy-to-electrical-energy converter. The kinetic-energy-to-electrical-energy converter converts kinetic energy provided by movement of the movable user interface element to electrical energy and provides the electrical energy to the wireless electronic device. In one embodiment, the wireless electronic device takes the form of a radio frequency identification (RFID) device with multiple identifiers and a control input.

Abstract: A radio frequency identification (RFID) device with multiple identifiers and a control input is disclosed. In one embodiment, the RFID device comprises a radio frequency (RF) transmitter, a plurality of identifiers, an input operative to receive a selection indicative of a set of the plurality of identifiers, and a control mechanism operative to cause the RF transmitter to transmit the set of identifiers indicated by the selection. The RFID device can comprise a single RFID tag or a plurality of RFID tags, with each RFID tag storing a respective one of the plurality of identifiers.

Abstract: This disclosure relates to wireless battery charging of electronic devices such as wireless headsets/headphones. In one embodiment, an electronic device is provided comprising a speaker comprising a coil, and the coil is operative both to cause the speaker to produce sound and to receive energy transferred to the coil via inductive coupling. The received energy is used to recharge a rechargeable battery in the electronic device. In other embodiments, the coil used to receive the energy that recharges the battery is received by a coil other than the coil in the speaker.

The network management software supports deployment and maintenance of wireless networks with no single point of failure, including medium failure.

Abstract: A tool is described to aid in the design and verification of multi-input, multi-output power supply systems. The designer describes the system requirements and constraints to the tool, which allows an iterative exploration of various alternative designs that satisfy the requirements and constraints. Alternative designs may comprise different power supply topologies, multiple controllers or multi-controllers, or configurable controllers that implement the power supply system. The tool generates a design for a power supply system that is reconfigurable to allow for performance optimization. The power supply system is configurable automatically according to a digital control signal. The digital control signal comprises configuration data which establishes the structure of the power supply system, and which determines the output power conditions of the power source.

Abstract: A power converter delivers electrical power from an electrical power source to a load according to a plurality of operation modes corresponding to different levels of input voltage or output current. The power converter comprises a power stage for delivering the electrical power from the power source to the load, a switch in the power stage that electrically couples or decouples the load to the power source, and a switch controller coupled to the switch for controlling the on-times and off-times of the switch according to the plurality of operation modes. Each of the operation modes correspond to associated ranges of at least one of an input voltage to the power converter and an output current from the power converter, where the associated ranges are different for each of the operation modes.
