| 20090243642 | Electronic Device Testing System and Method - The invention provides a testing system and method suitable for determining whether the pins of the socket are properly connected to a printed circuit board. The testing system includes a testing signal source, a socket, a signal sensing unit, a fixing element, and an analysis unit. The signal sensing unit comprises a sensor board, a probe, and an operation amplifier. The sensor board is electrically coupled to the socket, and the sensor board has a probing point. The probe is selectively contacted with the probing point of the sensor board for receiving and outputting a sensing signal. The operation amplifier is electrically connected to the probe for receiving, amplifying and outputting the sensing signal. The fixing element is used for fixing the sensor board between the socket and the fixing element. | 10-01-2009 |

| 20080218387 | VARIABLE LENGTH DECODER UTILIZING REORDERED INDEX DECODING LOOK-UP-TABLE (LUT) AND METHOD OF USING THE SAME - A variable length decoder and its decoding method utilizing a reordered index decoding look-up-table, and that is utilized to incorporate a plurality of decoding LUT's into a single reordered index decoding LUT for use in decoding by making use of the output correlation rule obtained through integrating a plurality of decoding LUT's. Thus, when proceeding with the variable length decodings, the multiplexer has only to select the correct reordered index value from among a plurality of reordered index values as based on the previous decoding results, and then find out the corresponding remapping index value and compensation value, thus searching and obtaining the corresponding reordered index output result in the reordered index decoding LUT through utilizing the remapping index value, hereby obtaining the output result through proceeding with the operations required by making use of the compensation value. | 09-11-2008 |

| 20110221691 | HANDHELD DEVICE CAPABLE OF AUTOMATICALLY SWITCHING BETWEEN A HANDHELD MODE AND A NON-HANDHELD MODE AND CONTROL METHOD THEREOF - A handheld device capable of automatically switching between a handheld mode and a non-handheld mode includes a sensing unit, a control unit, an operating unit, and a mode control unit. The sensing unit is used for generating a sensing result based on whether a user touch is received or not. The control unit sends out a charging-and-discharging signal to the sensing unit, and makes use of the charging-and-discharging signal to charge and discharge the sensing unit. The operating unit is coupled to the sensing unit for generating a mode control signal according to the sensing result. The mode control unit is coupled to the operating unit for controlling the handheld device to stay in a handheld mode or a non-handheld mode according to the mode control signal. | 09-15-2011 |
