Abstract: A method and apparatus are disclosed to control one or more input output (I/O) pads. An input signal is translated to an output signal having a desired logic level using a first latch loop. The state of the first latch loop is maintained by a second latch loop, integrated with the first latch loop, when a latching indication is received. The integration between the first latch loop and the second latch loop is such that the second latch loop creates an input-output connection if transmission gates in the second latch loop are conductive, and disables the input-output connection if the transmission gates are not conductive.

Abstract: A pair of pliers for removing fastening ring includes a pliers head, a pliers handle and a cover, wherein the pliers head comprises a left pliers head and a right pliers head, the pliers handle comprises a left pliers handle and a right pliers handle, and the left pliers head and the right pliers head are connected to a left pliers handle and a right pliers handle via a connecting shaft respectively, wherein the cover is provided at each of both sides of the pliers head via a head shaft, wherein the cutting edge of the left pliers head is blunt, and a projecting element is extended from an upper portion of the cutting edge of the left pliers head, the cutting edge of the right pliers head is a blade, and an adjusting device is provided at an upper portion of the left pliers handle and the right pliers handle.

Abstract: A hose clamp for clamping a pipe comprises a metal belt having a first edge and a second edge adapted for being overlapped defining a receiving cavity therein for clamping a pipe with a predetermined diameter, a positioning arrangement comprising a positioning head extended from said first edge of said metal belt, and a positioning head holder provided on said second edge at a corresponding place for receiving said positioning head, so as to guide said first edge and said second edge together in position; and a fastening arrangement comprising at least a welding arrangement comprising a first welding element provided on said first edge and a second welding element provided on said second edge at a corresponding place for being welded with said first welding point, so as to fasten said first edge and said second edge together.
