Abstract: A new and improved dock, and a new and improved wireless hand-held remote-control device, for controlling various sections of a powered chair, is disclosed, wherein the dock is adapted to be incorporated within, for example, an arm section of the powered chair, while the wireless hand-held remote-control device is adapted to be inserted into the dock so as not to be lost or misplaced. The wireless hand-held remote-control device has a plurality of control buttons disposed upon the primary or upper face portion thereof so as to control various sections of the powered chair, such as, for example, the headrest section, the back section, a lumbar support section, and a footrest section.

Abstract: A rapid detection device for multi-channel sporadic transient partial discharge, comprising a CPU and several partial discharge detection circuits. The partial discharge detection circuits are connected to a plurality of ports of the CPU one to one, respectively. First, a partial discharge pulse signal is filtered and amplified by means of a partial discharge pulse signal processing module in the partial discharge detection circuits, and is then inputted to a comparator, and a reference voltage passes through the CPU and is sent to a reference voltage processing module for amplification, filtering and other processing, and then is inputted to the comparator, so that the comparator processes same according to the partial discharge pulse signal and the reference voltage and then inputs same to a trigger. Finally, according to a level signal at an output terminal of the trigger, the CPU determines whether partial discharge occurs in a circuit to be detected.
