An electronic device includes: a frame including a side wall and at least partially forming an antenna; a bracket provided within the frame; a first printed circuit board provided on the bracket and including at least one grounding portion; a second printed circuit board provided within the frame; and a screw, where the second printed circuit board includes: a first portion coupled to the first printed circuit board; an extension portion extending from the first portion between the side wall of the frame and the bracket; a second portion extending from the extension portion between the first printed circuit board and the bracket; and a conductive trace extending from the first portion to the second portion through the extension portion, and where the conductive trace is electrically connected to the at least one grounding portion of the first printed circuit board in the second portion.

Wearable electronic device

A wireless power transmission device is provided. The wireless power transmission device includes a power input circuit, a communication module, a transmission coil, a power output circuit configured to apply output power to the transmission coil, and a processor. The processor may be configured to identify that a first input power is received from a first external power source through a first power input circuit, control the communication module to transmit first rating information corresponding to the first input power to the wireless power reception device, control the at least one communication module to receive, from the wireless power reception device, information on a first charging current determined based on the first rating information in the wireless power reception device, and control the power output circuit so that a first output power is applied to the transmission coil, based on the information on the first charging current.

Wireless power transmitter, wireless power receiver, and method for wirelessly transmitting power

A system for forming a negative pressure in a negative pressure reservoir of a brake system includes, an engine having an intake manifold and a camshaft, a vacuum pump connected to the camshaft through a clutch device and generating a pump negative pressure, a turbocharger having a compressor supplying a compressed air to the engine, a pump negative pressure line connecting the vacuum pump and the negative pressure reservoir and supplying the pump negative pressure to the negative pressure reservoir, an intake negative pressure line connecting the negative pressure reservoir and the intake manifold and supplying the intake negative pressure of the intake manifold to the negative pressure reservoir, and a negative pressure source selection apparatus configured to control opening and closing of the pump negative pressure line and the intake negative pressure line based on operation of the turbocharger.
