Abstract: A power cutoff device (20) comprises a power relay (21), a temperature calculation unit (22a), and a determination unit (22b). The power relay (21) includes a drive coil (21a). The temperature calculation unit (22a) calculates the temperature of the drive coil (21a) by calculating the resistance value of a resistor that changes with temperature when the drive coil (21a) included in the power relay (21) is regarded as a resistor. The determination unit (22b) determines whether or not to cut off the power supply on the basis of the temperature of the drive coil (21a) calculated by the temperature calculation unit (22a).

Abstract: A sensor device 10 includes a light projection unit 14, a light reception unit 15, an RGB value acquisition unit 22, a color index value calculation unit 24, and a determination unit 16. The light projection unit 14 projects light. The light reception unit 15 detects reflected light from an area illuminated with the light projected from the light projection unit 14. The RGB value acquisition unit 22 acquires color information about an object present in the illumination area on the basis of the reflected light detected by the light reception unit 15. The color index value calculation unit 24 calculates a single color index value on the basis of the R value, G value, and B value included in the color information acquired by the RGB value acquisition unit 22. The determination unit 16 compares the color index value calculated by the color index value calculation unit 24 with a specific threshold value to determine whether or not an object has been detected.

Abstract: A trigger switch capable of suppressing wear of a sliding electrode part and a device including the trigger switch are provided. A trigger switch includes a front sub-brush and a rear sub-brush that, when a drive part is driven by a movement of a trigger caused by a push-in operation to the trigger, move from an on-position where they contact a front sub-electrode and a rear sub-electrode on a substrate to an off-position where they do not contact the front sub-electrode and the rear sub-electrode. As the front sub-brush and the rear sub-brush move from the on-position to the off-position, a contact between the front sub-brush and the rear sub-brush and the substrate are released.
