Embodiment Construction
[0041] Such as figure 1 , the living body motion pattern sensing device in an embodiment of the present invention, the resistance sensing wire 11 and the heating wire 12 are arranged in parallel at a certain distance, and the two ends are connected at the terminals to form a closed-loop circuit with a part or the whole thereof.
[0042] The heating wire in an embodiment of the present invention includes a heating body or a structure that the outside of the heating wire 12 is shielded by the shielding portion 14 , and the outside of the heating wire 12 is covered with an insulator.
[0043]The heating wires 12 are arranged in a zigzag inside the body 10 of the electric heating pad, and the resistance sensing wires 11 and the heating wires 12 are arranged side by side at a certain distance.
[0044] The resistance sensing wire 11 arranged side by side with the heating wire 12 maintains a charged state with each other under the action of the shield portion 14 wound around the out...

The present invention relates to a living body movement pattern sensing device, which includes: a resistance sensing sensor formed in a closed-loop circuit within a use area range of a living body; an input node receiving the movement input from the resistance sensing sensor A pattern sensing signal, the life activity pattern sensing signal being a charged state between the resistance sensing sensor and ground based on a reference voltage, according to a change between a resistance sensing line and ground (without reference to ground) The voltage signal generated by the amount of change in the electrostatic capacity according to time, the electrostatic capacity is changed according to the activity of the living body close to the resistance sensing sensor (there is a problem with the Korean claim, please confirm); band-pass filter In the signal input through the input node, only the frequency band range corresponding to the living body activity pattern in the use state of the living body is passed; the operational amplifier amplifies the signal passing through the band-pass filter, and The set voltage is compared and output as a voltage signal capable of judging the use state of the living body.
Description
technical field [0001] The present invention relates to a moving pattern sensing device of a living body, a heating device including the same, a cooling device and a manufacturing method thereof, and the moving pattern sensing device of a living body senses an in-use state of a living body by distinguishing a moving pattern sensing signal of a living body . Background technique [0002] Electric heaters that use electricity as a heat source can be used not only for seats inside subway cars, seats in waiting rooms at bus stops, but also for outdoor seats. [0003] Only when the passenger sits on and uses it, the chair at the bus station or the heating device of the seat in the subway car is supplied with power for heating, thereby saving power and heating at the same time. [0004] The conventional temperature regulation and control device has nothing to do with the use of the user, until the temperature rises to the temperature set on the temperature regulation and control ...
