  • Patent number: 10340741
    Abstract: Disclosed is a refrigerator for uniformly illuminating an inner space thereof. The refrigerator includes a cabinet including a storage compartment having a predetermined size, a shelf installed in the storage compartment, the shelf including a light source unit for illuminating an inside of the storage compartment, a transmitter connected to an external power supply for wirelessly transmitting power, the transmitter having a primary resonance frequency within a predetermined range, and a receiver for wirelessly receiving the power from the transmitter so as to supply the power to the light source unit of the shelf, the transmitter transmitting the power to the receiver using a secondary resonance frequency generated when the receiver is located close to the transmitter.

  • Patent number: 10312737
    Abstract: A wireless power transmission system using multiple coils comprises a transmitter; and a receiver, wherein the transmitter includes a module for receiving a predetermined voltage, and a primary coil for generating a primary resonance frequency in accordance with the received voltage. The receiver spaced apart from the transmitter includes a load for emitting light, capacitors connected in series or in parallel in accordance with an equivalent resistance of the load, and a secondary coil for generating a secondary resonance frequency greater than the primary resonance frequency.

  • Patent number: 10302763
    Abstract: Disclosed are an electronic device and method for detecting the proximity of an object. In an embodiment, the electronic device includes a communication module, a sound emitter, a sound receiver, and a processor. The processor receives at least one part of a voice signal from a calling party through the communication module, and determines whether there is a voice idle time in the at least one part of the voice signal. When the voice idle time is present in the at least one part of the voice signal, the processor outputs a sound wave in an inaudible frequency band through the sound emitter during the voice idle time. Then the processor receives, through the sound receiver, sound wave in the inaudible frequency band reflected from an object. Next, the processor may detect whether the object is proximate to the electronic device using the reflected sound wave in the inaudible frequency band.
