Abstract: The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components.

Abstract: There is provided electrical contact for circuit boards. Each leg of the pin section has a deformable segment that can expand or contract along the direction of the leg to alleviate stress created by relative movement of printed circuit boards and/or off-board components interconnected thereby. The deformable segments have members that project in opposing directions relative to the direction of the leg, so that the segments are symmetrical. In one embodiment, each leg has a deformable segment having a outwardly curved shape. In another embodiment, each leg has a deformable segment in the shape of a rectangular frame. The deformable segments define at least one opening where the two legs of the pin section are not overlapping, which breaks the capillary flow of solder between the legs. The amount of solder that flows into the electrical contact is selectively controlled by the selected placement of the deformable segments.
