Abstract: An air cushion control system having an air chamber sensor including an air chamber, a bottom out sensor and an overinflation sensor, an air pump to inflate the air chamber, an air valve to release air from the air chamber, connections for the air cushion control system to an air cushion, and a microprocessor to control the inflation and the release of air from the air chamber. The air cushion control system reduces decubitus ulcers by incorporating both an automatic adjustment system to prevent the seated individual from bottoming-out in the air cushion and measure immersion depth to maximize pressure reduction.

Abstract: A wheelchair seating system preferably for use with an inflatable cushion device such as that incorporated herein by reference includes a base suitable for containing the components necessary to provide for either manual or automatic inflation and deflation of the lower cushion incorporated in the seating system and the upper cushion upon which a user sits.

Abstract: A shopping cart accessory (10) for providing a shopper with a support structure (16) having a number of support members (20, 22, 24, 28). The support members (20, 22, 24, 28) allow a locking type attachment of the accessory on a generaly upright wire (12) or solid portion (14) of a shopping cart or on any other wire member such as found on grocery store shelves. The shopping cart accessory (10) includes an integral writing instrument support (410). The shopping cart accessory further provides for locking attachment of the accessory on to wire shopping carts having wire members with different diameters.

Abstract: A shopping cart accessory for providing a shopper with a support for a notepad or calculator has a platform and a support structure having a number of support members. The support members allowing a locking-type attachment of the accessory on a generally upright wall portion of the shopping cart.

Abstract: An immersion control device. The device includes a fluid filled manifold and a fluid filled support device. Fluid pressure in the fluid filled support device equals fluid pressure in the fluid manifold notwithstanding respective fluid volumes. Immersion depth is controlled by increasing or decreasing fluid pressure. A fluid pressure regulator operates manually or automatically in response to a feedback of a fluid pressure change. Regulating members and spaced apart conductors or conductive stages can be used to provide feedback and activate an alarm, the fluid pressure regulator or both.
