Abstract: A power transmission apparatus includes a controller that controls a power transmitter that performs wireless power transmission. The controller is configured to: cause the processor to: cause the power transmitter to emit a first power transmission beam for which a first power is set; acquire feedback information on a result of reception of the first power transmission beam in a power reception apparatus; identify a power receiving capability in the power reception apparatus; and determine, with reference to the power receiving capability and the reception result, a second power which is usable in wireless power supply for the power reception apparatus and which is larger than the first power. The power receiving capability includes a maximum value of an input power range of the power reception apparatus. The wireless power transmission uses an electromagnetic wave having a frequency equal to or higher than that of a microwave.

Abstract: A liquid crystal television includes a display module generating heat, a substrate having a mounting surface and being placed at an interval from the display module, a component group mounted on the mounting surface, and a housing storing the display module, the substrate, and the component group. The mounting surface includes a first surface extending opposite to the display module and a second surface placed at a rear side of the first surface. A component in the component group having the greatest height with respect to the mounting surface is mounted on the first surface of the first surface and the second surface. The housing is provided with a first air vent hole positioned below the substrate and a second air vent hole positioned above the substrate. An airflow circulating through the first air vent hole, space between the display module and the first surface, and the second air vent hole is created within the housing.

Abstract: A liquid crystal television (100) includes a display module (10) generating heat, a substrate (21) having a mounting surface (22) and being placed at an interval from the display module (10), a component group (26) mounted on the mounting surface (22), and a housing (11) storing the display module (10), the substrate (21), and the component group (26). The mounting surface (22) includes a first surface (22a) extending opposite to the display module (10) and a second surface (22b) placed at a rear side of the first surface (22a). A component (26A) in the component group (26) having the greatest height with respect to the mounting surface (22) is mounted on the first surface (22a) of the first surface (22a) and the second surface (22b). The housing (11) is provided with a first air vent hole (18) positioned below the substrate (21) and a second air vent hole (19) positioned above the substrate (21).
