TL;DR: In this article, the power supply and information communication are achieved between electronic circuit substrates in the electronic equipment, and the size of the circuitry for achieving the above is reduced by reducing the number of wires.

TL;DR: In this paper, a power measuring system, a measuring apparatus, a load terminal, and a device control system are provided, where a voltage sensor detects a voltage waveform and a current sensor acquires a current waveform, of a power line in a noncontact manner.

TL;DR: In this article, the authors proposed a synchronous motor driving device with rectangular wave excitation in which any excitation width between 120° and 180° inclusive is selectable and sine wave excitations can be accomplished by one piece of circuitry, and the excitation wave form can be changed in a very short time according to driving conditions (high-efficiency driving conditions, low-noise driving conditions) required for a motor to be driven.

TL;DR: In this article, the authors proposed a wireless power supply and wireless information communication between electronic circuit boards in an electronic device, and to reduce the size of means for achieving the wireless power supplies and the wireless information communications.

TL;DR: In this article, a noncontact transmission device that achieves power transmission and data communication by a pair of coils so as to achieve the cost reduction is presented. But the authors do not consider the effect of the power received from the receiving part on the power transmitted from the transmitting part.
