    Abstract: When pressure detected by a pressure sensor connected to a calibration standard cell has continuously fallen within a regulated pressure range at calibration for a regulated duration at calibration, zero-adjustment is performed based on the pressure value detected by the pressure sensor. Then, communication between the plurality of cells is created to perform internal pressure adjustment of the plurality of cells to a predetermined internal pressure value, based on the pressure value detected by the pressure sensor connected to the calibration standard cell and calibrate each of pressure sensors connecting to the plurality of cells, based on the adjusted internal pressure. With this scheme, it is possible to a mattress and the like that can perform zero-point adjustment efficiently by adjusting the zero point in the same manner even if the mattress is formed of a plurality of branches, without releasing the pressure sensor of each cell to atmospheric pressure.

  • Publication number: 20140373274
    Abstract: A cushion for inserting in the legwell between individual seats in rows of seats, for example in a vehicle, is disclosed. The top of the cushion can act as a surface for a user to lie down. The cushion can be inflatable and can be deflated for easy transport. The cushion can have multiple reservoirs so the internal pressure can be separately adjusted for the base and for the mattress of the cushion, similar to a box spring and a mattress in a common bed.

  • Patent number: 8914928
    Abstract: An alternating pressure pad (1) comprises inflatable cells (9,10) supplied with air by supply lines (7, 8) from a compressor (2) via supply line (3). A pressure controller controls the output of the compressor. Also connected to supply line (3) is an angle detection valve (40) restricting flow of air to atmosphere with increase in its angular position and a pressure transducer (17). Any increase in pressure due to an increase in angle of the detection valve (19) results in back pressure in the detection line. The pressure controller (2) uses the pressure transducer (17) to detect this change in pressure and then acts to adjust compressor output to the cells (9, 10) accordingly. The angle detection valve (40) is positioned under the head section of the pad to move with the head rest section.

  • Patent number: 8910331
    Abstract: The present invention relates to a cushion for preventing pressure sore. The cushion for preventing pressure sore includes an air cell layer, an air passage layer, a base layer, and a plurality of air ducts. The air cell layer has a plurality of air cells; the air cell layer is divided into at least four air cell zones. Air cells in each air cell zone are in communication with each other, but air cells in any two adjacent air cell zones are not in communication with each other; the air passage layer is under the air cell layer and has a plurality of air passages therein. Each air passage is in connection and communication with at least one of the air cell zones; the air passage layer and the air cell layer are disposed on the base layer; an end of each air duct is in communication with a corresponding air passage, and the other end extends out of the cushion and is provided with a joint; and each air duct has a respective valve.

  • Patent number: 8893338
    Abstract: A cushion or mattress comprising a base and a plurality of linearly aligned individual air cells across the base. Groups of individual air cells can be interconnected and in fluid cooperation with an inflation source, such as a pump. In one aspect of the invention, the inflation of adjacent cells is staggered, for example, in a checkerboard-like inflation pattern that helps diffuse load over a wider area.

  • Patent number: RE47680
    Abstract: A medical air mattress has a mattress body, a lower bedspread, an upper bedspread and a guardrail unit. The mattress body is formed by multiple air cells parallel arranged in an air cell row. The upper bedspread covers the mattress body and has two guardrail sleeves formed on the upper bedspread. The guardrail unit has multiple guardrail air cells mounted respectively in the guardrail sleeves. Since the guardrail sleeves are formed on the upper bedspread, the guardrail sleeves from each opposite side of the upper bedspread will draw each other to maintain the guardrail sleeves in position when pressed. Therefore, the guardrail sleeves do not fall down when pressed to remain providing optimal protection purpose.
