  • Patent number: 5990799
    Abstract: A chair occupancy monitoring device having pressure sensitive switch housed within a flexible cover. A cushion formed by a pair of foam pads positioned between the cover and the switch protects the switch and increases patient comfort. The switch includes first and second oppositely disposed base members. First and second electrical conductors are mounted to an interior portion of the first and second base members, respectively, on the surface facing the opposing base member. A gap is created between the electrical conductors by a pair of separator members which are disposed intermediate the oppositely disposed surfaces of the first and second base members and are mounted to a side portion of at least one of the base members. At least one electrically non-conductive contact limiter member is disposed intermediate the electrical conductors, covering a portion of the second electrical conductor.

  • Patent number: 5796059
    Abstract: A pressure-sensitive switch apparatus for use in monitoring the position of a patient in a bed or chair is provided. The switch includes a resilient conductor disposed between first and second conductors located at opposite surface areas of the switch. The resilient conductor provides varying degrees of electrical contact between the first and second electrical conductors in response to pressure applied to either of these conductors by shifting of the patient's weight.
