  • Patent number: 10675199
    Abstract: A patient support structure includes a first supporting part, a second supporting part and a third supporting part. The first supporting part includes a first resilient member; the second supporting part includes a second resilient member; and the third supporting part is between the first supporting part and the second supporting part. The first supporting part, the second supporting part and the third supporting part together define a supporting surface extending along a longitudinal axis, and the second resilient member includes a first supporting area and a second supporting area different in supporting strength.

  • Patent number: 10085569
    Abstract: An inflation and deflation pressure regulation system is applicable to an air mattress with at least two air arrays, the inflation and deflation pressure regulation system comprising an inflation and deflation device, a pressure detection unit and a control unit. The inflation and deflation device inflates or deflates the air mattress; the pressure detection unit continuously detects an instantaneous pressure value of the air mattress; the control unit determines whether the instantaneous pressure value detected by the pressure detection unit when the air mattress is in a weight-bearing state has reached a preset pressure value before a preset time has elapsed, and accordingly uses a first inflation and deflation strategy or a second inflation and deflation strategy to control the inflation and deflation device to inflate or deflate the air mattress.

  • Patent number: 9263822
    Abstract: A wire terminal structure capable of fully enclosing internal components to prevent external dust or impurity from entering the insulation case to affect the normal operation thereof. The wire terminal structure includes an insulation case and a conductive holding frame disposed in the case. The case is formed with a wire socket and a press window. The conductive holding frame has an elastic holding member corresponding to the wire socket. The elastic holding member is formed with a holding mouth. A push section is disposed on the elastic holding member corresponding to the press window. A pushbutton is elastically movably disposed in the press window between the press window and the push section. The pushbutton is spaced from the case. When an external force is applied to the pushbutton, the pushbutton is elastically moved to push the push section and open the holding mouth.

  • Patent number: 9240650
    Abstract: A terminal block assembly includes a terminal block and lever member and is less structurally complicated and less likely to deform as compared to the existing terminal block products. The terminal block has a main body and a chamber defined by the main body. The chamber is provided with a metal spring piece, which, in response to movements of the lever member, crimps a leading wire to form electrical connection or release the leading wire. The chamber is also provided with a buckle that performs reciprocating movements and is biased by a spring to normally engage with the lever member. When receiving an operating force, the buckle disengages with the lever member so that the lever member is allowed to move. The terminal block assembly advantageously provides easy and effort-saving operation.

  • Patent number: 8809825
    Abstract: A paper size detection device includes a central switch, at least two switches disposed to two opposite sides of the central switch at intervals, and at least a sensor corresponding to the two switches located at the two opposite sides of the central switch. The sensor can be designated as a light sensor. One switch triggers the sensor and the other switch is without triggering the sensor under an original no paper condition. So that a detection method of the paper size detection device that uses N light sensors to judge N*2 papers' size can be realized by virtue of the above-mentioned setting structure, N is a positive integer, such as 2, 3, 4 and so on. Thus, the paper size detection device has a simple structure and a lower manufacture cost, and the detection method of the paper size detection device is simplified, accordingly.
