Abstract: A mounted object detection device includes: a load sensor in which a plurality of sensor parts each configured to detect a load are disposed in a matrix shape; and a controller configured to detect a situation of a mounted object on the load sensor on the basis of an output from the load sensor. The controller: detects a load distribution on a detection region of the load sensor on the basis of an output from the load sensor; discerns which of a person or animal and a thing the mounted object is, on the basis of the load distribution; and when having discerned that the mounted object is a thing, discerns whether or not a person or an animal is mounted on the thing, on the basis of temporal change in the load distribution.

Abstract: A load sensor includes: a first base member and a second base member disposed so as to face each other; an electrically-conductive elastic body disposed on an opposing face of the first base member; and a conductor wire disposed between the second base member and the electrically-conductive elastic body and configured as a plurality of element wires being twisted. Each element wire is configured as an electrically-conductive member which has a linear shape and of which the surface is covered by a dielectric body. A twist pitch of the plurality of element wires satisfies a conditional expression “p≤12nd”. In the expression, p is the twist pitch of the plurality of element wires, n is the number of the element wires included in the conductor wire and d is the outer diameter of each element wire.

Abstract: A capacitance detection device includes: a sensor unit including a plurality of sensor elements; row control lines; column control lines; a control circuit supplying a charging voltage to the sensor element; and an equipotential circuit outputting a potential equal to the potential of the sensor element subject to measurement. The control circuit applies a charging voltage to the row control line connected to the sensor element and connects the column control line connected to the sensor element to the ground potential side. The control circuit causes the equipotential circuit to set a potential of at least one of the row control lines other than the row control line connected to the sensor element subject to measurement and the column control lines other than the column control line connected to the sensor element subject to measurement to a potential equal to the potential of the sensor element subject to measurement.
