    Abstract: A pressure sensing pad or mat comprises a piezoresistive layer, a top electrically conductive layer comprising a plurality of electrically conductive top strips extending in a first direction along one side of the piezoresistive layer, a bottom electrically conductive layer comprising a plurality of electrically conductive bottom strips extending in a second direction, nonparallel to the first direction, along the other side of the piezoresistive layer, and top and bottom adhesive layers holding the top and bottom strips against the piezoresistive layer so as to inhibit relative displacement of the strips relative to the piezoresistive layer and relative to each other. Also disclosed are a method of manufacturing the pressure sensor pad, a pressure sensing system that employs the a sensor mat, and a pressure map display for displaying a pressure distribution of an object resting on the pressure sensing mat.

    Abstract: A lateral rotation apparatus includes a first adjustable frame positioned under a head segment of a person support surface and operable to rotate the head segment of the person support surface to a head tilt angle in the range of about 7 to about 30 degrees relative to a horizontal support plane. A second adjustable frame is positioned under a torso segment of a person support surface and operable to rotate the torso segment of the person support surface to a torso tilt angle that is within a range of about 5 degrees to about 10 degrees less than the head tilt angle. Each of the first adjustable frame and the second adjustable frame includes an upper frame positioned below the person support surface, and a lower frame coupled to and positioned below the upper frame. The upper frame being moveable with respect to the lower frame.
