Abstract: An electronic device includes a touch panel, a driving circuit, and a sensing circuit. The driving circuit generates a driving signal, and superposes phase information on the driving signal. The touch panel includes multiple crossing conductors, for providing a sensing signal in response to a contact of an object on one of the sensing conductors and to a driving signal applied on the sensing element. The sensing circuit includes a signal extractor and a tag detector. The signal extractor generates a demodulation signal based on the period of the driving signal, width of the phase information, and for demodulating the sensing signal by using the demodulation signal to determine a sensing value. The tag detector enables the signal extractor as soon as a magnitude of the sensing signal is over a predetermined threshold. The signal demodulates the sensing signal by using a demodulation signal whose period is the same as the driving signal to determine the sensing value.

Abstract: A touch sensing apparatus utilizes the characteristics of orthogonal vectors is disclosed. A random spread spectrum (RSS) signal or a periodic wave is used to modulate a driving signal so as to driving a row of a sensing array, and the RSS signal or periodic wave is also use to extract touch information of a node from a sensing signal measured from a column of the sensing array. The node is an intersection of the driven row and the measured column. When different RSS signals and/or periodic waves are used to drive multiple rows simultaneously, multipoint touching information can be obtained from the same sensing signal at the same time by respectively using the RSS signals and/or periodic waves to extract touching information of multiple points which are the intersections of the driven rows and the measured column.

A sensing signal is measured from a column, for example, of the sensing array. Touching information is extracted by using the random duration square wave signal to demodulate the sensing signal.

The parameter adjusting unit receives and adjusts N number of brightness values of the RGB pixels and the common chroma value and stores them in a form of compressed image data into a memory.

Abstract: A positioning module positions the location of the mobile communication apparatus. A determination module stores a map and determines whether the location of the mobile communication apparatus is within one of the effective communication ranges of the available base stations based on the map. A processing module ceases searching for the signals of available base stations if the location of the mobile communication apparatus is determined not to be within one of the effective communication ranges. A mobile communication apparatus can cease searching for the signals of available base stations if the mobile communication apparatus is not within one of the effective communication ranges of any available base stations or the search takes too much time. Therefore, power is saved.
