Abstract: Patches for battery-interfacing devices and associated systems and methods are disclosed. A patch device in accordance with one embodiment includes a storage medium having a patch, the patch including information that is not specific to only the patch device. The patch device can further include a data terminal coupled to the storage medium and coupleable to a corresponding data terminal of a battery port of a host device. The patch is transmissible away from the storage medium via the data terminal. A method in accordance with a particular embodiment includes powering a host device by connecting a battery pack to the host device via a power terminal and a data terminal of the battery pack and corresponding power terminal and data terminal of the host device. Information is conveyed to the host device via the data terminal of the battery pack that is specific to just the battery pack.

Abstract: A system for using inductive coils to transfer energy to a wireless mouse thereby allowing the wireless mouse to refresh its rechargeable batteries while at the same time being operated over the surface containing the sending inductive coil or coils.

Abstract: A rechargeable power pack comprises a housing, an energy storage device received in the housing, and a set of contacts extending from the housing and electrically coupled to the energy storage device to provide an electrical input current to the energy storage device at a first time and an electrical output current from the energy storage device at a second time. The electrical contacts are preferably formed as a set of prongs sized and dimensioned to be received in a standard electrical outlet. The rechargeable power pack may contain a charging circuit, a discharging circuit, and a switch to selectively couple the charging circuit and the discharging circuit between the contacts and the energy storage device. Additional circuitry may be provided for decoupling the charging circuit when either a voltage, temperature, or time has exceeded some predefined value.
