Abstract:
A wireless device includes a circuit board, a communicator disposed on the circuit board, and a casing accommodating the circuit board and the communicator. The casing has a through-hole in a side face. An antenna element is disposed on the exterior of the casing. A feeder extends through the through-hole in the casing and feeds electrical power from the communicator to the antenna element at a predetermined feeding position. A ground terminal extends through the through-hole in the casing and electrically connects the circuit board to the antenna element at a ground position of the antenna element at a predetermined distance from the feeding position.
Abstract:
An electronic device includes a case with an opening portion; a cover member arranged in the opening portion so as to close the opening portion; a seal member provided between an outer circumferential surface of the cover member and an inner circumferential surface of the opening portion; a reinforcing portion made of a nonconductive material and provided, in the case, on a portion outside the inner circumferential surface in a direction orthogonal to an axial direction of the opening portion; an antenna; and an electronic component arranged in the case and configured to process a radio wave received by the antenna.

Abstract:
The effect of prolonged skin contact with an electronic apparatus is appropriately suppressed. An electronic apparatus 1 includes a temperature acquisition unit 54, a temperature integration unit 55, and a temperature management unit 56. The temperature acquisition unit 54 acquires the temperature of the apparatus. The temperature integration unit 55 acquires information (limit time) about the effect on the skin which changes depending on the temperature. The temperature management unit 56 executes a preset process, based on the temperature of the apparatus acquired by the temperature acquisition unit 54 and the information about the effect on the skin acquired by the temperature integration unit 55.
