    Abstract: An air cushion bed includes an inflatable air mattress; a first sensing mat provided on an outer surface of the air mattress and including a first upper and a first lower sensing sheet with a first soft pad sandwiched between them; and a first determining module electrically connected to the first upper and lower sensing sheets. When the first sensing mat is compressed and the first upper and lower sensing sheets are electrically connected to each other via holes on the first soft pad, the first determining module determines there is a patient lying on the air mattress or the air mattress with a patient lying thereon is insufficiently inflated. A second sensing mat and a second determining module can be additionally provided on another outer surface of the air mattress opposite to the first sensing mat for the air cushion bed to determine both of the above two situations.

    Abstract: A mattress and a capacitive immersion system for adjusting the support that the mattress provides to a user are disclosed. In one embodiment, a mattress includes one or more air cells and a capacitive immersion system. The system relates generated capacitance between conductors mounted to an air cell to a pressure inside the air cells on which the conductors are mounted. More specifically, the measured capacitance may be related to a distance between the conductors. This distance may then be related to pressure with the air cells. The air cell may be inflated or deflated as required or desired to maintain a suitable minimum distance or distance that a user finds to be subjectively comfortable.

  • Patent number: 8156589
    Abstract: Disclosed herein is an air mattress including at least two separate zones. A first and second groups of elongate, inflatable cells are disposed alternately within each of the at least two separate zones. An air pump is to supply pressurized air. At least two air distributors are serially connected with the air pump for respectively distributing the pressurized air to the at least two separate zones. Each air distributor is operable to supply the pressurized air to the first and second groups of cells within each of the at least two separate zones. A pressure reducer is serially connected between any adjacent two of the at least two distributors for reducing the pressure of the pressurized air to a downstream one of any adjacent two of the at least two distributors.

  • Patent number: 8151390
    Abstract: An inflatable bed includes a bedstead assembly, a mattress assembly, and an electrical air pump unit. The mattress assembly is disposed on and above the bedstead assembly, and includes a top sheet, a bottom sheet disposed under the top sheet, and a plurality of surrounding sheets interconnecting the top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other. Each of the air chambers is defined among the top sheet, the bottom sheet, and a respective one of the surrounding sheets. The electrical air pump unit is disposed on the bedstead assembly, and is operable to inflate the air chambers individually so that air pressures in the air chambers may be different.
