Abstract: A gamma tap circuit includes: (i) a first gamma division circuit configured to generate a first gamma tap voltage by performing voltage division of an upper gamma tap voltage and a lower gamma tap voltage, in-sync with a first clock signal CK1 and a first complementary clock signal CK1b, which is 180° out-of-phase relative to CK1, (ii) a second gamma division circuit configured to generate a second gamma tap voltage by performing voltage division of the upper gamma tap voltage and the first gamma tap voltage, in-sync with a second clock signal CK2 and a second complementary clock signal CK2b, which is 180° out-of-phase relative to CK2, and (iii) a third gamma division circuit configured to generate a third gamma tap voltage by performing voltage division of the first gamma tap voltage and the lower gamma tap voltage, in response to CK2 and CK2b, which have a lower frequency relative to CK1 and CK1b.

Abstract: A disassemblable far infrared knee-and-foot warming device includes a bottom plate, a top plate, a front frame, a curved plate, a plurality of screws and an opening. By operating the screws, the bottom plate, the top plate, the front frame and the curved plate can be assembled or disassembled, and the curved plate is provided with a far infrared heating plate. Thereby, the far infrared heating plate generates far infrared thermal energy, and the warming device can be easily disassembled for saving costs related to packaging, storage and transportation, and can be easily reassembled for use.

Abstract: The sauna room assembly contains a bottom frame, left and right front walls, left and right back, columns, left and right walls, a back wall a top frame, a top cover, a floor and a door. A major characteristic of the present invention is that each of the aforementioned members is in turn broken down into at least two pieces, and most members have their pieces in substantially identical dimensions. The sauna room assembly therefore can be disassembled into pieces small and standard enough for high portability. Another major characteristic of the present invention is that most of the pieces are joined together through tabling and only few bolts are required. Therefore, a single novice can put the sauna room assembly together with standard hand tools such as screwdrivers.

Abstract: A heating device includes a case having a plurality of openings and a plurality of slits are defined in bars of the case so that a plurality of heating boards are engaged with the slits of the case at an equal distance. A power control device is connected to the case and includes a power line having a plurality of male connectors. Each heating board includes a heating layer sandwiched between two isolation plates. Two wires are connected to the heating layer and each wire has female connectors, which are connected with the male connectors of the power line. The heating layers of the heating boards dispense heat evenly from the openings of the case.

Abstract: A sauna apparatus includes a housing having a plurality of walls, and a plurality of heating pads attached respectively to the walls. Each of the heating pads of the sauna apparatus includes a flat heating body, and a flat electrical insulator enclosing the flat heating body.

Abstract: An electric heating cushion device includes a heating member in form of a flexible sheet, and including upper and lower dielectric layers and an electric heating film layer disposed therebetween to generate heat when supplied with electric power. Two opposite end portions of the heating member are in a permanent interengagement with each other to roll the heat member into a tubular body, thereby defining a cylindrical space in the tubular body. A cushion member is removably inserted in the cylindrical space. An electric wire unit is connected electrically to the electric heating film layer and an electric power source.

Abstract: An electric heating device includes a heating member, a closure unit and an electric wire unit. The heating member is formed as a flexible sheet with opposite first and second end portions. The heating member has upper and lower dielectric layers and an electric heating film layer which is disposed between the upper and lower dielectric layers and which generates heat when supplied with electric power. The closure unit is provided on the first and second end portions of the heating member for connecting the first and second end portions to each other so as to form the heating member into a tubular body and so as to retain a tubular shape of the heating member. The electric wire unit is connected electrically to the electric heating film layer, and is adapted to be connected electrically to an electric power source.
