Abstract: An airbed system, connectable to an air mattress chamber of an air mattress, includes: a pressure sensor, configured to obtain pressure measurements corresponding to the air mattress chamber; and a control unit, configured to operate a pump and valves of the airbed system to inflate and deflate the air mattress chamber, and to determine first and second constants corresponding to inflation of the air mattress chamber and third and fourth constants corresponding to deflation of the air mattress chamber.

Abstract: A cover assembly internally supported by a removable irregular object provides a seating apparatus. A top cover and a bottom cover are separated allowing access to the object within. A cushion assembly conforms to the irregular upper surface of the object forming a generally uniform top surface for the cover assembly. Foam structural supports in the corners of the cover assembly provide additional structural support and padding. A back support provides support for a person sitting on the cover assembly.

Abstract: A configurable seating assembly includes a plurality of rectangular pad assemblies disposed within a durable cover assembly. The cover includes a generally triangular or tapered upper chamber forming a back support portion above a generally rectangular lower chamber forming a body support portion. A wedge assembly, manufactured from a foam material, is removably positioned in the upper chamber, and the pads, manufactured from a foam material, are positioned in the compartments of a separator assembly within the lower chamber thereby providing a seating apparatus. A front panel at the forward end of the lower chamber provides an opening into the cover assembly allowing insertion and removal of the wedge and pads. The pads may be removed from the cover and arranged on the floor providing pads for sleeping. The front panel is releasably secured to the cover by cooperating removable connectors.
