| 20090295688 | PLASMA DISPLAY APPARATUS AND METHOD OF DRIVING THE SAME - A plasma display apparatus and a method of driving the same are disclosed. The method includes assigning a predetermined number of sustain signals to each of subfields constituting a frame depending on weight values of the subfields, selecting some of combinations of the subfields, actually measuring a luminance of light emitted by the plasma display apparatus during a frame comprised of the selected subfield combination, normalizing a luminance corresponding to each subfield combination depending on the actually measured highest luminance to calculate a reference normalized gray level, and calculating an intermediate gray level between the reference normalized gray levels. | 12-03-2009 |
| 20090303232 | DISPLAY APPARATUS - A display apparatus is disclosed. The display apparatus includes a display panel that displays at least one of a two dimensional (2D) image and a three dimensional (3D) image, and a driver that is driven so as to display an image on the display panel. The driver includes a 3D image conversion unit that converts the 3D image into a protective image if a length of a period during which the 3D image is displayed on the display panel is longer than a length of a first period. | 12-10-2009 |
| 20110096057 | PLASMA DISPLAY APPARATUS - A plasma display apparatus is disclosed. The plasma display apparatus includes a plasma display panel that displays a left eye image and a right eye image before and after a crosstalk prevention period during a frame, a first driver that supplies a data signal for the left eye image and the right eye image to the plasma display panel, and a second driver that supplies a sustain signal to discharge cells of the plasma display panel selected by the supply of the data signal. | 04-28-2011 |

| 20100045446 | RFID SYSTEM USING HUMAN BODY COMMUNICATION - An a Radio Frequency Identification (RFID) system using human body communication includes a first electrode pad receiving a signal of a reader transmitted through a human body, or outputting an output signal to the human body, a rectifier rectifying the signal of the reader to generate a direct current (DC) voltage, a power manager changing the DC voltage into an operation voltage, a modulator/demodulator demodulating the signal of the reader, or modulating the output signal of the tag to transfer the modulated signal to the first electrode pad, a digital controller performing a read or write operation in response to the signal of the reader demodulated by the modulator/demodulator, and a memory storing identification information of the tag and information according to an operation result of the digital controller. | 02-25-2010 |
| 20100322290 | MODULATION AND DEMODULATION APPARATUS USING FREQUENCY SELECTIVE BASEBAND AND TRANSMISSION AND RECEPTION APPARATUS USING THE SAME - There is provided a communication method using a human body as a medium. A modulation apparatus using a frequency selective baseband according to an aspect of the invention may include: a serial-to-parallel conversion unit converting serial data supplied from an upper layer into parallel data consisting of M+1 number of data input bits; and a frequency selective spreader selecting one subgroup among a plurality of subgroups obtained by dividing 2 | 12-23-2010 |
| 20110006926 | TRAINING APPARATUS AND METHOD BASED ON MOTION CONTENT - A training apparatus based on motion content includes a plurality of motion detecting sensors ( | 01-13-2011 |
| 20110019717 | HUMAN BODY COMMUNICATION APPARATUS FOR NON-CONTACT COMMUNICATIONS AND HUMAN BODY COMMUNICATION METHOD FOR NON-CONTACT COMMUNICATIONS IN THE SAME USING FREQUENCY SELECTIVE BASEBAND - Provided are a human body communication apparatus for non-contact communications using a frequency-selective baseband and a human body communication method for non-contact communications in the same. The human body communication apparatus may be useful to perform stable communications between users by reducing interference induced from other communication apparatuses without affecting interference between the users since data are transmitted/received between communication apparatuses adjacent to a human body by spreading and despreading the data using only spreading codes of a limited frequency band (frequency-selective baseband) in which an inductive electromagnetic field formed by an antenna shows the most effective characteristics. | 01-27-2011 |
| 20110040492 | SYSTEM AND METHOD FOR MEASURING PHASE RESPONSE CHARACTERISTIC OF HUMAN-BODY IN HUMAN-BODY COMMUNICATION - There is provided a system and a method for measuring phase response characteristic of a human body in human-body communication. The system and method may be useful to measure phase response characteristic of the human body without forming a common ground line between a reference signal transmitter and a reference signal receiver by transmitting a first reference signal through the human body and transmitting a second reference signal through the optical cable. | 02-17-2011 |
| 20110123032 | SINGLE SOUND TRANSMISSION APPARATUS USING HUMAN BODY COMMUNICATON - Provided is a single sound transmission apparatus using human body communication. The single sound transmission apparatus includes a sound signal generator generating a sound signal of an audio frequency band, a high frequency signal generator generating a high frequency signal having a higher frequency than the audio frequency band, a signal combiner generating a combined signal by combining the sound signal with the high frequency signal, and a signal transmitter varying a phase difference between the combined signal outputted from the signal combiner and the high frequency signal outputted from the high frequency signal generator, and outputting the combined signal and the high frequency signal together to a human body, in order to leave only the sound signal through destructive interference of the high frequency signal of the combined signal, wherein the destructive interference is generated in an ear area of the human body. | 05-26-2011 |
