Abstract: According to one embodiment, a sensor includes a detection device and a circuit portion. The detection device includes a first detection portion and a second detection portion. The first detection portion includes a first detection element. The first detection element includes a first conductive member and a first detection member. The second detection portion includes a second detection element. The second detection element includes a second conductive member and a second detection member. The circuit portion is configured to execute a first detection portion operation for outputting a first detection result corresponding to a first detection value based on the first detection member when a first current is supplied to the first conductive member. In a case where a first evaluation value is not within a first range, the circuit portion is configured to execute a second detection portion operation by the second detection portion.

Abstract: According to one embodiment, a sensor includes a detection device, a switch circuit, and a detection circuit. The detection device includes a first detection section and a second detection section. The first detection section includes a first detection element. The first detection element includes a first conductive member and a first resistance member. The second detection section includes a second detection element.

In a first operation, the switch circuit is configured to supply a first current to the first conductive member and not to supply the first current to the second conductive member, and the detection circuit is configured to output a first signal corresponding to a difference between a first electrical resistance of the first resistance member and a second electrical resistance of the second resistance member.

Abstract: A virtual guide sensor processing unit of an automatic guided vehicle (AGV) computes the position of a virtual guide tape on the basis of the position of the AGV which a vehicle body coordinate value calculation processing unit has computed, and virtual guide tape layout data. A guide sensor switching processing unit outputs to a vehicle body deviation degree calculation processing unit the position of a magnetic guide tape which a magnetic guide sensor has detected, or the position of the virtual guide tape which the virtual guide sensor processing unit has computed.

Abstract: Provided area device and the like which make it possible to prolong the operation duration time of a load using a capacitor as a main power supply. If a capacitor voltage V1 is equal to or higher than a first reference voltage Vth1, then electric power that has not undergone a step-up operation by a converter (12) is supplied from a capacitor (11) to an electric motor (14), which is a load. Meanwhile, if the discharge capacitance of the capacitor (11) decreases due to the supply of electric power to the electric motor (14), which is the load, causing the capacitor voltage V1 to decrease to become lower than the first reference voltage Vth1, then electric power that has undergone the step-up operation by the converter (12) is supplied to the load from the capacitor (11).
