A display control device () comprises an image acquisition component (), an orientation estimation component (), and a controller (). The image acquisition component () acquires an infrared image (G) sensed by infrared array sensors (and) installed in a room. The orientation estimation component () estimates the orientation of a care receiver (P) in a room () on the basis of the infrared image (G) acquired by the image acquisition component (). The controller () controls a display device () so that a dummy image (D), which shows a simplified view of the orientation of the care receiver (P) estimated by the orientation estimation component (), is displayed superimposed over the infrared image (G).

A power generation device converts vibrational energy into electric power using a vibrational power generation element in which an electret is provided on one substrate of substrates configured to be relatively movable while maintaining a mutually facing state, and supplies the electric power. A vibrational power generation element has the same configuration as the vibrational power generation element and converts vibrational energy into electric power. The vibrational power generation element is connected to a light-emitting diode via a bridge-type full wave rectifier circuit constituted by diodes, a smoothing circuit constituted by a capacitor, and a light-emitting diode drive circuit. A power generation state of the power generation device using the vibrational power generation element and the like is displayed by blinking of the light-emitting diode.

An actuator includes: an electrostatic actuation mechanism including a stationary electrode and a movable electrode; a first movable part driven by the electrostatic actuation mechanism; a first elastic support part that elastically supports the first movable part; an electret formed in at least one of the stationary electrode and the movable electrode; and a drive control unit that controls application of voltage to the electrostatic actuation mechanism. In the actuator a plurality of stable states are set in which the first movable part is positioned at a stable position at which an electrostatic force generated by the electret matches with an elastic force exerted by the first elastic support part or at a stable position near such stable position. By applying a voltage to the electrostatic actuation mechanism, the first movable part may be displaced from any stable position to another stable position.

A pressure-detecting chamber , a pressure-directing path and a buffer space are formed on the upper face of a main-body-side substrate as recessed portions, and the upper face of the pressure-detecting chamber is covered with a thin-type diaphragm , and upper faces of the pressure-directing path and the buffer space are covered with a cover substrate . A pressure-introducing unit formed on the lower face of the main-body-side substrate is connected to the lower face of the buffer space . The cross-section of the buffer space is greater than the cross-section of the pressure-introducing unit , and the capacity of the buffer space is greater than the capacity of the pressure-directing path . With this arrangement, it is possible to provide a pressure sensor which can control the response characteristic of the pressure sensor to a pressure change with high precision without causing serious adverse effects on the other characteristics of the pressure sensor, without preventing the miniaturization of the sensor.
