Abstract: A seat with a heating device is provided which realizes a configuration in which the arm, palms and finger tips of a user can easily be warmed when the user uses the seat with the heating device. When the user is seated in a seat with a heating device and feels cold due to it being winter, the user controls a switch to heat the seat, whereby energization of heating elements 3a, 3b, 3c is started which are connected to a power supply via electric wires. When the energization of the heating elements 3a, 3b, 3c is started, heat generated thereby is conducted to skin materials 2a, 2b, 2c and surfaces of the skin materials are warmed. When the user places his or her arm on an armrest portion 5, the arm is warmed via the skin material 2c, whereby the user can feel the sensation of comfortableness.

Abstract: A vehicle seating system is provided in which infrared rays radiated from a surface of a thermal radiation member at the time of heating are emitted to a bodily portion of an occupant which extends from his or her head to shoulders for implementation of effective heading. In a case of a planar heating element 2 being installed above a side windowpane, the planar heating element 2 is installed so as to confront an upper body of an occupant who is seated in a seat which extends from his or her head to shoulders, and when the planar heating element 2 is energized, an upper body of the front-seat occupant can be warmed by radiation heat. In a case of a planar heating element 3 being installed in a center pillar portion, when the planar heating element 3 is energized, the upper body of the front-seat occupant can be warmed by radiation heat.

Abstract: As a switch for detecting operation of a door handle, a contact joint switch, a capacitance type sensor, etc., is available, but involves problems of a contact failure caused by secular change and a malfunction caused by rain and is not excellent in a multifunctional property used for other applications. A contact detector of the invention includes support means (8) having a moving part displacing upon reception of contact; a cable-like piezoelectric sensor (4) having a part supported by the support means (8) and becoming deformed in conjunction with displacement of the moving part (8c); and signal processing means for performing signal processing of output of the cable-like piezoelectric sensor (8), wherein the cable-like piezoelectric sensor (8) has a bend part (4a) to form a plurality of simultaneous deformation parts and the simultaneous deformation parts become deformed in conjunction with the moving part (8c), whereby contact is detected.

Abstract: An object of the invention is to provide a monitoring device that can be mounted in a window or a door in which because the window is often opened or closed by the user, if the monitoring device is installed on the window, the user must perform an operation of releasing the monitoring device, every time of opening or closing the window. An intrusion detecting terminal unit (13) having an opening/closing sensor is disposed on the window or door, a mat (16) containing a piezoelectric sensor (15) is disposed near under the window, and each of the intrusion detecting terminal unit (13) with the opening/closing sensor and the intrusion detecting terminal unit (15a) with the piezoelectric sensor comprises data communication means for transmitting or receiving data. In case of the intrusion, the intrusion detecting terminal unit (15a) under the window detects the intruder, and then if the intruder tries to open the window, the intruder is judged.

Abstract: To provide an intrusion detection device that can be easily mounted, has less influence of rain or snow, has a weather resistance, and can cope with various shapes. In the intrusion detection device of the present invention, pressure sensitive means (14) that is a flexible cable-like piezoelectric sensor is stored in a packet (13) in a sealed state, and mounted on a wall-like structure (11) such as a veranda, a balcony or a fence for the domicile. Since the packet is slidable, the pressure sensitive means is sufficiently deformed when the wall-like structure (11) is pressed, so that the sensor can make the detection reliably.

Abstract: While there are contact joining and capacitance type switches for detecting an operation of a door handle, a problem that is to be solved by the invention is to solve problems of contact failure due to aging and a malfunction triggered by rain drops. According to the invention, a piezoelectric sensor (4) has such flexibility as to be annexed to a door handle (3), whereby a minute displacement of the door handle (3) can be detected with high sensitivity. Consequently, a sufficient signal output can be obtained only through a simple touch to the door handle (3), whereby a touch or contact to the door handle (3) can be detected. In addition, since electrodes are not exposed to the outside, the piezoelectric sensor (4) is made difficult to be affected by disturbance, and dust, rain, snow and the like which come to adhere thereto.
