摘要:
A body support such as a cushion, mattress, chair or the like has at least one inflatable air chamber. A pressure sensor senses interface pressures at different locations on a surface of the air chamber. Indicators derived from the interface pressures indicate the onset of a trend toward bottoming out. A controller controls air pressure within the air chamber based at least in part on values of the indicators. The controller may be implemented as a state machine.

This disclosure describes a mattress having a plurality of vertically-oriented inflatable bladders and a pneumatic box located inside the mattress. In one embodiment, the patient support includes a plurality of pressure sensors positioned underneath the bladders. In still another embodiment, the patient support includes one or more filler portions that are selectable so that the patient support may conform to bed frames having different deck configurations.
摘要:
A patient support having real time pressure control. The patient support includes a plurality of sensors located beneath a bladder including a plurality of upright cylindrical elements. The pressure within the bladder is controlled based on the pressure or force sensed by the plurality of sensors.
摘要:
This disclosure describes certain exemplary embodiments of a patient support having a plurality of vertically-oriented or substantially can-shaped inflatable bladders. In one embodiment, the patient support includes a plurality of pressure sensors positioned underneath the bladders. In another embodiment, the patient support includes a support layer positioned above the vertical bladders. In still another embodiment, the patient support includes one or more filler portions that are selectable so that the patient support may conform to bed frames having different deck configurations.

A method for verifying the identity of a person comprises providing a plurality of pressure transducers and deriving a key from pressures measured by the pressure transducers when a person presses a hand (or other body part) against the pressure transducers. The key can be compared to a previously stored reference key. Apparatus for verifying the identity of a person may have an array of pressure transducers coupled to a controller. The controller produces the key and compares it to a reference key.
摘要:
An input device has a flexible surface on which are formed deflection sensors. The flexible surface can be deformed against an adjacent resilient layer. The deflection sensors detect the deflection of the surface. Electronic circuits for processing signals from the deflection sensors to yield information regarding the locations and magnitudes of forces deflecting the surface may be deposited all, or in part on the flexible surface. The input device may be combined with a display to yield a touch-sensitive display suitable for use in a wide range of applications.
