Abstract: A system for authenticating a rechargeable battery and for detecting counterfeit batteries includes battery characteristics detection circuitry and a battery. Battery characteristics detection circuitry performs an authentication routine on the battery such that battery characteristics of the battery are measured. Battery characteristics include state of health, state of charge, internal resistance, relaxation time, and impedance. The battery is validated by comparing the battery characteristics to validation parameters provided by a manufacturer. If battery characteristics are within ranges of the validation parameters, then the battery is authenticated as originating from a particular manufacturer or batch. If validation fails, then the device is disabled or protected. In one example, validation parameters are stored and compared locally on a device. In another example, the device communicates battery characteristics to a remote entity that performs the validation.

Abstract: A clamping device comprises a fixing frame for assembling to a nail gun, a clamping arm pivoted to one side of the fixing frame and swung relative to a nail output of the nail gun connected to the fixing frame, a cylinder having a telescopic rod and linked to the clamping arm, and a pipeline fluidly communicated with the cylinder and a pneumatic supply. The fixing frame is fixed corresponding to the nail output so as to easily assemble and disassemble. An air pressure through the pipeline is driving the telescopic rod and the clamping arm to swing relative to the fixing frame. A lay-up is clamped by the clamping arm to abut against the nail output for nailing and piercing. It may be easily detached from the nail gun after finishing constructing so that the multiple functions of the nail gun may be achieved.
