Abstract: A rechargeable battery pack system includes a retention cage, a reserve power module, and a rechargeable battery pack. The retention cage is removably attachable over a battery compartment of a game controller. The reserve power module has first electrical contacts that contact battery contacts of the game controller for providing electrical power from the reserve power module to the game controller when the reserve power module is in the retention cage and the retention cage is attached to the game controller. The rechargeable battery pack has electrical contacts to contact second electrical contacts of the reserve power module for providing electrical power to the reserve power module and to the game controller, through the reserve power module. The reserve power module can uninterruptedly power the game controller when the depleted rechargeable battery pack is removed from the retention cage to be replaced by a charged rechargeable battery pack.

Abstract: A rechargeable battery pack includes a rechargeable battery, electrical circuitry, and an inductive coil for wirelessly transmitting power to an electronic device. The rechargeable battery pack further includes a first set of electrical contacts to interface with electrical contacts of a charging base. The rechargeable battery pack is programmed to transmit a first data communication including a first identification code to the charging base through the first set of electrical contacts and receive first electrical power from the charging base if the identification code is verified. The rechargeable battery pack includes a second set of electrical contacts positioned on a top surface of the rechargeable battery pack for providing second electrical power to a second instance of the rechargeable battery pack. The second electrical power provided to the second instance of the rechargeable battery pack is a portion of the first electrical power received from the charging base.

Abstract: A rechargeable battery pack system includes a charging base and rechargeable battery packs. The charging base includes an electrical connector for receiving electrical power and a set of electrical contacts. The rechargeable battery packs each include a rechargeable battery, electrical circuitry, and an inductive coil for wirelessly transmitting power to an electronic device. The rechargeable battery packs each include a first set of electrical contacts to electrically contact the charging base for receiving electrical power from the charging base when the battery pack is stacked on top. The rechargeable battery packs further include a second set of electrical contacts for providing electrical power to another rechargeable battery pack when the other rechargeable battery pack is stacked on top. The second set of electrical contacts is activated for providing the electrical power to the other rechargeable battery pack only after receiving a proper identity code from the other rechargeable battery.

Abstract: A solar charging system for a portable electronic device includes an electrical connector adapted to be removably coupled to an electrical interface of the portable electronic device. A rechargeable battery is electrically coupled to the electrical connector, and the rechargeable battery is adapted to store a stored electrical power. A solar panel is electrically coupled to the rechargeable battery such that the received electrical power is stored in the rechargeable battery as stored electrical power. When the electrical connector is electrically coupled to the electrical interface of the installed portable electronic device, stored electrical power is provided or conveyed to the portable electronic device. When the electrical connector is not electrically coupled to the electrical interface of the installed portable electronic device, the received electrical power is stored in the rechargeable battery as stored electrical power.

Abstract: A beacon includes a housing, multiple directional radio frequency antennas, a multiplexer, and a signal source that produces a signal output. The directional radio frequency antennas are attached to the housing such that each directional radio frequency antenna points out radially from an axis of the housing in a direction different than the other directional radio frequency antennas. The multiplexer is electrically connected to each of the directional radio frequency antennas and to the signal source. The multiplexer is configured to sequentially conduct the radio signal output from the signal source to each of the directional radio frequency antennas to produce a wireless signal, wherein the signal output is only conducted to one of the directional radio frequency antennas at any given time and includes a unique identifier identifying the antenna it is currently being transmitted from. The beacon may also include electrical hardware for performing time of flight measurements.
