Abstract: An incontinence detection device comprising a pad with a plurality of circuits. The circuit conductors are spaced on the pad, with each of the circuits defining a linear dimension across a respective pair of the circuit conductors. The linear dimension has a correlation to a predetermined liquid volume of an incontinent event desired to be detected. A controller applies voltage from a power source to and checks continuity of the spaced circuits and totals the circuits. The controller indicates to a care provider that an incontinent event has occurred at a certain minimum liquid volume.

Abstract: An electromagnetic drive means for providing motion. An application is as an indicator device for registering the magnitude of an input supplied to a computer by an external sensor is described. The electromagnetic drive means includes a first stationary member that comprises electrically conductive material having a serpentine configuration that defines a plurality of alternating peaks and troughs which are selectively magnetized to provide alternating north and south magnetic fields. A second member is movable along the path of the stationary member by discrete and controlled magnetic attraction and repulsion forces set up between the members. The stationary members can be provided with a graduated scale while the movable member carries a pointer that is movable with respect to the scale to thereby indicate a magnitude of the input. A specific application of this indicator device is as a gauge in a dashboard.
