Abstract: An apparatus and a method for reducing wireless data transmission in a personal area network is configured to generate and transmit a packet including information discriminating between a synchronous channel and a data channel. The apparatus and method discriminate between the synchronous channel and data channel when receiving a packet in order to improve data transmission performance of a human body communication system. The apparatus and the method use a transmission channel whose frequency is lower than an antenna frequency as a synchronous channel, and use a transmission channel whose frequency is higher than the antenna frequency as a data channel.

Abstract: A tactile input/output device and a driving method thereof are provided. The device includes at least one input end, at least one output end, and a controller. The input end includes a plurality of input cells arranged at regular intervals. The output end includes a plurality of output cells arranged at regular intervals. The controller senses an input signal of the input end and controls the output end to generate a corresponding output signal. The input end and the output end are installed to form one array with being separated. The input cell and the output cell are arranged so that they do not overlap with each other.

Abstract: A seismic reinforcing structure is disclosed, which is for a power supplying distribution panel or panelboard mounted on a raised access floor system in order to reinforce a seismic capacity. More particularly, the seismic reinforcing structure can be mounted even to an existing operating distribution panel or panelboard having a seismic capacity without requiring transfer or power interruption of the distribution panel or panelboard in operation.

Abstract: An input apparatus and method for tactile sensing are disclosed. The input apparatus includes a sensor array for outputting input data in an array format according to a touch input, and a controller for obtaining first input data for a first input from the sensor array if the first input above a predetermined pressure is imposed on the sensor array, for obtaining second input data for a second input from the sensor array if the second input above a predetermined pressure is imposed on the sensor array, for generating third input data indicating an input characteristic by comparing the first input data and the second input data, and for operating according to a program based on the third input data.

Abstract: Disclosed is an apparatus and method for signal detection according to frequency bands used in an RFID system. The apparatus includes a low-noise amplifier for low-noise amplifying a received signal, a receiver unit for detecting a CW signal and a tag signal, a transmitter unit for frequency up-converting and outputting an input signal, a PLL for generating a frequency signal according to a transmission signal band or a reception signal band, a receiver unit switch for connecting the receiver unit with the low-noise amplifier or a directional coupler, an antennas switch for connecting the antenna with the directional coupler or low-noise amplifier, and a controller unit for controlling a frequency of the frequency signal generated by the PLL, turning off transmission power in a case of an LBT scheme, controlling the receiver unit switch and the antenna switch, and determining if a corresponding channel is an idle channel.

Abstract: Disclosed is a semiconductor chip comprising power pads for receiving power, a plurality of pad groups grouped according to functions in such a manner that each pad group includes at least one input/output pad, separated power rings connected to each of pad groups and for delivering power supplied from the power pads to each of the pad groups, and a switch control unit for determining usage states for input/output pads of the pad groups and for performing on/off control with respect to each of the pad groups. The pad group comprises at least simultaneously-operating input/output pad, and is grouped in such a manner that the pad group includes at least two pads sharing power supplied from one power pad. A switch control unit determines a usage state for each of the pad groups and, as a result of the determination, turns off input/output pads of an idle pad group.
