Abstract: A self contained patient sensing and monitoring system is provided for sensing and monitoring the presence, absence, and movement of the patient. Embodiments of the present invention provide a system conformable to a patient support surface, systems that are self contained, systems that are operationally unobtrusive, and programmable systems. Embodiments of the present invention comprise a container, a sensor configured within the container, and a control unit responsive to the sensor and configured within the container, wherein the container at least substantially encompassing the sensor and the control unit and wherein the control unit is conformable to the patient support surface. Some embodiments of the present invention comprise a container, a sensor configured within the container, and a control unit conformable to a patient support surface and configured within the container, wherein said control unit is responsive to the sensor.

Abstract: A conformal electrical sensor switch for determining the presence or absence of weight, such as a person in a bed, comprises flexible, parallel sensing strips positioned to make contact when pressure is applied. Sensing strip circuits are held apart by a separator strip until pressure is applied and thus closing a latch which provides signal output through snap connectors which are affixed to the sensing strips and which extend beyond the sealed flexible cover of the sensor switch. The flexible cover serves to secure the sensing strips and connectors in a facing relationship. The connectors are designed to permit easy attachment to a variety of signal processing/monitoring devices.

Abstract: A rigid shell or framework (10) for a building structure, comprising a first pair of spaced supporting frames (11, 12) defining the end walls of the shell, a second pair of spaced supporting frames (13, 14) disposed at right angles to the first pair of frames and defining the side walls of the shell, and a plurality of further supporting frames (15) disposed intermediate the first pair of supporting frames, being supported by the second pair of frames, and in turn providing the structural support for the side walls, roof and floor defined by the rigid shell.The first pair of supporting frames comprises a pair of vertical load-bearing members (18, 19) integral with and secured to a pair of horizontal load-bearing elements (16, 17) at points spaced from the ends of such elements by from 1/8th to 1/4th their respective lengths.
