Abstract: An example device includes a wireless charging circuit to wirelessly charge a portable electronic device. The device further includes a first photosensor positioned within an effective charging range of the wireless charging circuit, the first photosensor to output a first signal, and a second photosensor positioned outside the effective charging range, the second photosensor to output a second signal. The device further includes a control circuit connected to the wireless charging circuit, the first photosensor, and the second photosensor. The control circuit detects the portable electronic device positioned within the effective charging range of the wireless charging circuit by detecting a difference between the first signal and the second signal. The control circuit turns on the wireless charging circuit in response to detecting the difference. The control circuit turns off the wireless charging circuit in response to detecting that the first signal matches the second signal.

Abstract: Example implementations relate to transmitting signals via USB ports. For example, a system according to the present disclosure, may include a host module including a plurality of USB ports, a first expansion module, and a second expansion module. The first expansion module may include a first USB port and a second USB port. The first expansion module may receive a signal from the host module at a first USB port, and direct the signal to a second USB port. The first expansion module may transmit the signal to a second expansion module via a second USB port.
