Abstract: An element array circuit includes one or more first wiring lines, second wiring lines, impedance elements, one or more operational amplifiers, one or more conversion elements, and one or more switchers. The second wiring lines each extend in a direction different from a direction of extension of the first wiring lines. The impedance elements are each coupled to one each of the first and second wiring lines. The operational amplifiers each include a positive input terminal, a negative input terminal couplable to one of the second wiring lines, and an output terminal. The conversion elements are each coupled to the negative input terminal and the output terminal, and each convert a current flowing through the second wiring line coupled to the negative input terminal into a voltage. The switchers are each coupled to one of the conversion elements and come into a conducting state or a nonconducting state.

Abstract: A tire deterioration detection system, a tire wear detection system and a tire wear detection method can suppress influences caused by curving of a vehicle. The tire deterioration detection system estimates deterioration state, for example, wear state of each tire of a vehicle. A calculation part derives a moving length of each tire in view of an effect caused by curving based on a traveling path of the vehicle obtained from position data by a GPS receiver and an outer diameter of the tire from the moving length of the tire, so that calculation part derives a wear loss of the tire and estimate the wear state of the tire from the wear loss of the tire.

Abstract: An element array circuit includes first wirings including respective first parts, second wirings including respective second parts, and impedance elements each coupled to both one of the first wirings and one of the second wirings. The second parts extend in a direction different from that in which the first parts extend. Each of the second wirings includes a readout line through which signals flow, the signals indicating states of multiple ones of the impedance elements coupled to relevant one of the second wirings. Each of the first parts is a part, of relevant one of the first wirings, to which multiple ones of the impedance elements are coupled. Each of the second parts is a part, of relevant one of the second wirings, to which multiple ones of the impedance elements are coupled. The first parts are smaller than the second parts in electrical resistance value per unit length.

Abstract: A wireless power receiving device includes a voltage detection unit that detects an output voltage value of a rectifying unit, a power reduction unit that includes a switching element connected to a charging unit in parallel, and a control unit that controls operations of the switching element. In a case where the output voltage value detected by the voltage detection unit exceeds a first reference voltage value set in advance, the control unit controls and turns the switching element on by applying a voltage to the switching element, and controls the value of the voltage to be applied to the switching element so that the difference between the voltage value calculated on the basis of a current flowing in the switching element and a second reference voltage value set in advance decreases.
