Abstract:
PURPOSE: A data coding method for a 3D broadcast and a device thereof are provided to enable a user to watch a 3D broadcast while watching an existing 2D broadcast in a broadcast system. CONSTITUTION: An audio encoder(204) receives a voice signal. The audio encoder encodes the inputted voice signal using a voice signal compression algorithm. The audio encoder transfers the encoded signal to a multiplexer(206). The multiplexer multiplexes image signals encoded by a right image encoder(200) and a left image encoder(202), a voice signal encoded by the audio encoder, control data, and sub data. The multiplexer generates a transport stream.
Abstract:
PURPOSE: An energy expenditure apparatus using wireless sensor nodes and a system using the same are provided to accurately measure the momentum of a user by reflecting geographical features in user's exercise route. CONSTITUTION: A wireless sensor node(100) and a plurality of receiving nodes(200) collect data for measuring the momentum of a user(10) along user's moving route. The plurality of receiving nodes are installed at regular intervals on the moving route. The wireless sensor node comprises a communication module for periodically transmitting a lower-power wireless signal to the receiving nodes. The plurality of receiving nodes record the intensity of a received wireless signal.
Abstract:
PURPOSE: A multi-mode wireless power transmission system using magnetic resonance induction and a charging method thereof are provided to efficiently charge wireless chargeable devices by utilizing other wireless chargeable devices as repeaters. CONSTITUTION: A wireless power transmission apparatus(100) transmits a charge ON signal to wireless chargeable devices(200_4,200_6) to charge and a repeater signal to wireless chargeable devices(200_3,200_5) which does not need charge. A control unit of a wireless chargeable device receiving the charge ON signal turns off a switch in an adaptive matching network and turns on a power control switch. A wireless chargeable device receiving the repeater signal turns on both the switches.
