Wireless charger decreased in variation of charging efficiency

A wireless charger charges a storage battery of a portable electronic device in a wireless manner (non-contacting or contact-less) so that a variation of charging efficiency is not serious though the storage battery is placed any position of the wireless charger. The wireless charger is provided with a primary coil for generating a magnetic field so as to charge a subject, which is provided with a secondary coil, by means of inductive coupling with the secondary coil. The primary coil includes an outer coil arranged with a predetermined winding number and a predetermined size; and at least one inner coil arranged to be included inside the outer coil. The outer coil and the inner coil are arranged so that, when a primary current is applied to the outer coil and the inner coil, magnetic fluxes generated in the outer coil and the inner coil are formed in the same direction.

Electronic Device with Sensing Assembly and Method for Detecting Basic Gestures

An electronic device and method are described for detecting a predefined gesture that is a specified pattern of movement of an external object relative to the electronic device. The method includes providing as part of the electronic device a sensing assembly including at least one photoreceiver and a plurality of phototransmitters, wherein each phototransmitter is positioned to emit infrared light away from the electronic device about a corresponding central transmission axis, wherein each central transmission axis is oriented in a different direction with respect to the others. The emission of infrared light by each of the phototransmitters is controlled during each of a plurality of sequential time periods, and wherein the external, object moves in the specified pattern of movement during the plurality of sequential time periods. For each of the plurality of phototransmitters and for each of the plurality of sequential time periods, a corresponding measured signal indicative of a respective amount of infrared light which originated from that phototransmitter during that time period and was reflected by the external object prior to being received by the photoreceiver is generated, and the measured signals are evaluated to detect the predefined gesture.
