Abstract: A heat release device includes a housing, a substrate located within the housing, a heat source disposed on the substrate, a first member provided between the housing and the substrate and between the housing and the heat source, and a plurality of second members that support the first member from the substrate. The first member is disposed to have a gap with the heat source and so as to have a gap with the housing. Among the plurality of second members, a second member far from the heat source is larger in area in contact with the substrate and the first member than a second member close to the heat source.

Abstract: The handset is connected to a cord that can be unreeled and reeled in, and can be set in a cradle and taken out of the cradle, the handset comprising an acceleration sensor, a display unit, and a controller. The acceleration sensor detects movement of the handset in a first direction, which is a direction in which the handset is taken out of the cradle, and/or a second direction, which is a direction in which the handset is set in the cradle. The controller controls operation of the display unit, and disables the operation of the display unit while the acceleration sensor is detecting movement of the handset in the first direction or the second direction.

Abstract: A reclining state determination device includes a detecting unit, an image capturing unit, and a control unit. The detecting unit detects an acceleration of a display device attached, so as to be capable of tilting, to a rear surface of a reclining seat. The image capturing unit captures an image from the display device. The control unit determines a reclining state of the reclining seat on the basis of the captured image and the detected acceleration.

Abstract: An electronic device includes (i) an input-volume measuring section (23) for measuring input volume, which is volume of a sound inputted into the sound input section (17) while the sound output section (16) is performing sound output, (ii) a feedback-volume estimating section (24) for estimating estimated volume, estimated volume is volume of a sound which is to be inputted into the sound input section (17) in a state in which there is no object which blocks the sound in a predetermined range, (iii) volume determination section (26) for determining whether or not the input volume is lower than the estimated volume, and (iv) a function control section (21) for carrying out a predetermined process if the input volume is lower than the estimated volume.
