Patent ID: 8823529

Claim:
A patient monitoring system for use proximate a doorway with a door, the system comprising: a motion detection unit including a motion detection sensor and a first housing supporting the motion detection sensor; a control unit including control circuitry, at least one light operably coupled with the control circuitry and a second housing supporting the control circuitry and the light, the light indicating one of an alarm condition and a non-alarm condition by selective illumination of the light; wiring extending between the first housing and the second housing and operably coupling the motion detection sensor with the control circuitry wherein the control circuitry receives signals from the motion detection sensor; a door sensor assembly securable proximate a door, the door sensor assembly being operably coupled with the control circuit and thereby communicating the open/closed status of the door to the control circuitry; and wherein the control circuitry is configured to place the light in the alarm condition when the motion detector senses movement and the door sensor assembly detects that the door is closed.
