In a terminal device of a switching device, a terminal screw with a washer is screwed in a terminal strip having a screw hole therein for connecting an external wire. The buffer generates an output signal that is a delayed version of a signal presented at the input node. The method may also provide the ability to input and store text annotations associated with each person, face, and video segment, and the ability to enroll and remove people from database. The sensor array package can be embedded in a printed circuit board enabling the bond wires to terminate at other conductors within the printed circuit board. The invention further relates to a method for detecting or quantitating an analyte gas.
