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 laser light source device includes a semiconductor laser, a current supplying unit to supply a driving current to the semiconductor laser, and a signal generator to generate current intensity data for setting an intensity of the driving current. The signal generator generates, for an input signal corresponding to continuous pixels for a same color, a plurality of sets of the current intensity data indicating current intensities different from each other, and transmits the plurality of sets of the current intensity data to the current supplying unit while sequentially switching the plurality of sets of the current intensity data. The current supplying unit drives the semiconductor laser based on the plurality of different sets of the current intensity data.

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: The disclosure provides a light source device and an image display device. The light source device includes a laser light source configured to emit laser light having a wavelength in a range from 635 nm to 645 nm inclusive, a temperature sensor configured to detect temperature around the light source device, and a laser control circuit configured to control the laser light source. The laser control circuit approximates, with use of a quartic expression, change in threshold current of the laser light source relative to temperature, and approximates, with use of a quadratic expression, change in slope efficiency of the laser light source relative to temperature, to obtain threshold current and slope efficiency of the laser light source corresponding to detection temperature of the temperature sensor, and controls the laser light source in accordance with the threshold current and the slope efficiency thus obtained.
