Abstract: A heat flux sensor is installed in such a way that heat flux emanating from a biological object present at a predetermined position is detectable. It is determined whether or not a biological object is present at the predetermined position by comparing sensing results of the heat flux sensor with determination criteria. The determination criteria is preset according to heat flux that can be sensed when a biological object is present at the predetermined position. When the sensing results of the heat flux sensor satisfy the determination criteria, in other words, when the heat flux sensed by the heat flux sensor is the heat flux emanating from a biological object, it is determined that a biological object is present at the predetermined position. Consequently, it is possible to realize accurate detection of a biological object.

Abstract: A heat quantity control device has a heat flux sensor arranged between first and second heating elements arranged adjacently to each other, and a control section for controlling a heat quantity of the first and second heating elements. The heat flux sensor has an insulation board made of thermoplastic resin, first and second via holes formed in the insulation board penetrating in a thickness direction thereof. First and second layer connection members are embedded in the first and second via holes, respectively. The first and second layer connection members are made of different metals and alternately connected in series. The control section controls a heat quantity generated in the first and second heating elements based on the electromotive force generated in the heat flux sensors so that a heat flux flowing between the first and second heating elements becomes not more than a predetermined value.

Abstract: There is provided a heat flux sensor with first and second interlayer connection members composed of different metals from each other of which metal atoms maintain a predetermined crystal structure embedded in first and second via holes of a thermoplastic resin made insulating substrate, the first and the second interlayer connection members are connected in series alternately, and a control unit that performs abnormality determination of a heating element disposed in a vehicle. The heat flux sensor is provided to the heating element and outputs a sensor signal corresponding to heat flux between the heating element and an outside air, and the control unit determines based on the sensor signal that there is abnormality in the heating element when the heat flux between the heating element and the outside air is out of a predetermined range.
