Wireless electrically operated apparatus e.g. personal computer, for wireless data communication, has output device for visually and/or acoustically signaling reception field strength and characteristic curve of received electrical energy

摘要

The apparatus has a receiver (20) for receiving wirelessly transferred electrical energy for supplying to the electrically operated apparatus and/or for charging a battery assigned for the apparatus, and an output device e.g. LED display, for visually and/or acoustically signaling reception field strength and a characteristic curve of the electrical energy received by the receiver. The output device indicates whether the electrical energy received by the receiver is reduced and/or increased, if the placement of the electrically operated apparatus is changed.
