Abstract: A cuff for measuring volume and change in volume of a body appendage includes a hollow, rigid tube having an inner surface; and a bladder having an inner surface and an outer surface, the ends of the bladder being sealed to the ends of the tube to create an enclosed internal volume between the inner surface of the bladder and the inner surface of the tube and an external volume defined by the outer surface of the bladder and surrounded by the internal volume, the bladder having a normal, relaxed state, in which the internal volume is filled with a fluid and a retracted state in which the fluid is evacuated from the internal volume. Two stiffener ribs placed on the inner surface of the bladder, parallel to each other and to the lengthwise axis of the tube at diametrically opposite positions. A plurality of emitters and detectors arranged in a linear array are embedded in one of the ribs, so as to emit and detect light through the bladder.

Abstract: A fuse stab connector for electronic modules is described in which a fuse is associated with an electronic module so that the connector for the fuse to a circuit also serves as an electromechanical connector of a module to the fuse, a primary circuit, and primary circuit mechanical structure.

Abstract: A varistor-based voltage suppression circuit is coupled to a power distribution system having at least one power line and at least one neutral line. A varistor is coupled directly to the power and neutral lines of the distribution circuit so that the electric current travels across at least one planar surface of the varistor, thus eliminating one or more leads from the distribution circuit to the varistor circuit. The suppression circuit may be a single varistor or a number of varistors in parallel with a number of lines in the distribution circuit.
