20100144292 | ACTIVE RF MODULE - An active radio frequency module which is capable of coping with a wide frequency band or a multiband by applying a control signal to a module including a single antenna and radio frequency circuits. The active RF module varies and adjusts a frequency band according to a desired characteristic by arranging control elements, whose impedance characteristics are varied depending on applied voltage, at locations adapted for frequency characteristics of an antenna, a filter and a power amplifier, and applying a proper direct voltage to the control elements according to an external signal. Accordingly, it is possible to reduce space for RF stages while easily setting a desired frequency characteristic. In addition, the active RF module can be used over a wide range including various wireless terminals and allows reduction of costs and time for development of RF stages. | 06-10-2010 |

20130177236 | METHOD AND APPARATUS FOR PROCESSING DEPTH IMAGE - An apparatus and method for processing a depth image. A depth image may be generated with reduced noise and motion blur, using depth images generated during different integration times that are generated based on the noise and motion blur of the depth image. | 07-11-2013 |
20150303992 | DATA COMMUNICATING METHOD FOR USE IN A SINGLE-WIRE PROTOCOL COMMUNICATION AND A SINGLE-WIRE PROTOCOL COMMUNICATION SYSTEM USING THE SAME - A data communication method in a single-wire protocol communication is provided. The method includes determining a number of first data bits having a logical high state or a number of second data bits having a logical low state from among data bits in a communication packet, determining whether the number of the first data bits exceeds a first predetermined number or the number of the second data bits is below a second predetermined number, inverting the data bits in the communication packet when the number of the first data bits exceeds the first predetermined number or the number of the second data bits is below the second determined number, and transferring the inverted data bits to a reception side via a single-wire input/output. | 10-22-2015 |
