US 9,814,410 B2 · Person support apparatus with position monitoring

Abstract

A person support apparatus includes one or more thermal image sensors whose outputs are analyzed to perform one or more functions. Such functions include automatically turning on a brake, automatically turning on one or more lights, detecting when a patient associated with the person support apparatus has fallen, enabling a propulsion system of the patient support apparatus to be used, automatically controlling one or more environmental controls, and/or automatically arming an exit detection system after entry of a patient onto the person support apparatus. Multiple thermal images may be generated from multiple sensors to generate stereoscopic thermal images of portions of the person support apparatus and its surroundings.

Dependent claims

A person support apparatus comprising:

a support surface adapted to support a person thereon;
a first sensor adapted to detect electromagnetic waves coming from the person when the person is supported on the support surface;
a second sensor adapted to detect a force exerted by the person while the person is supported on the support surface;
a memory in which a location of the first sensor with respect to the support surface is stored;
and
a controller adapted to correlate information from the first and second sensors in order to determine a position of the person on the support surface, the controller using the location of the first sensor with respect to the support surface when determining the position of the person on the support surface.
