Abstract: A tissue monitoring device for selecting, administering or adjusting a treatment based on information obtained by monitoring the tissue. The device includes a substrate for applying to the tissue, for example, a human or an animal external, or internal tissue, including vascular tissue; a light source supported by the substrate, the light source emitting light of a first frequency for directing the emitted light onto a surface of the tissue; a photodetector carried by the substrate spaced from the light source for detecting scattered light, wherein the scattered light is the emitted light scattered by the tissue; and a controller in communication with the photodetector and the light source.

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.
