Abstract: A combination handheld mobile device and rechargeable battery system includes the handheld mobile device having a body and being portable; and the rechargeable battery system operably associated with and to provide electrical energy to the handheld mobile device, the rechargeable battery system having a battery having a body with a partial hollow cavity; a power port conductively coupled to the battery and carried within the partial hollow cavity; and a terminal conductively coupled to the battery and carried on an outside surface of the body; and the power port is to receive a power cord to recharge the battery via an internal charger associated with the power port; and the terminal is to engage with a docking station to recharge the battery.

Abstract: A new type of passive battery pack short circuit protection is provided in a battery pack consisting of one or more battery cells, with on load charge and on load conditioning-discharge capability, having a minimum of only 2 terminals. At least one voltage clamping device is included in the charge path of the battery to provide both charge and conditioning-discharge capability. A charging system provides both charging and discharging controls so that current can be either charged to or discharged from the battery through the voltage clamping device. The breakdown voltage of the voltage clamping device is selected to be equal to or greater than the maximum battery voltage, thus providing short circuit protection of the battery pack while still allowing a discharge function with a minimum of 2 terminals.

Abstract: An arc fault circuit breaker assembled such that electrical interconnections, i.e., electrical connections between compartments, are made without disassembling any previously assembled compartment. The arc fault circuit breaker comprises housings having compartments within. Electrically connected components having interconnecting components, i.e., components which provide electrical interconnections between compartments, are disposed within the compartments. The housings are assembled together to enclose the compartments. Interconnecting components within an enclosed compartment extend through openings in the housings to provide electrical interconnections to the next compartment to be assembled. Therefore, no disassembly of the enclosed compartment is necessary to make the interconnections.
