Publication number: 20130278520Abstract: A touch control method is implemented in an electronic system. A calculation of the product of a pressure value and the area over which pressure is applied are included in touch input data packets representing a touch operation, the values of net force associated with the touch input packets are thus obtained. A signal of a short press, if recognized, with a value of net force greater than a net force threshold can be recognized as a signal of a long press, thus simulating an operation of long press and triggering the selection of an object, where the selection of the object would otherwise require a long press operation. The touch control method operates to significantly speed up selection of an object.Type: ApplicationFiled: April 19, 2013Publication date: October 24, 2013Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: CHENG-HAO WENG, DENG-RUNG LIU, CHI-CHANG LU

Publication number: 20130227265Abstract: A media data playback device comprises first and second nonvolatile memories. The first nonvolatile memory stores a boot loader and a kernel of an operating system in a compressed format. The second nonvolatile memory serves as a main memory of the device. A processor executes the boot loader to load and decompress the kernel from the first nonvolatile memory to the second nonvolatile memory in response to a boot command. When receiving a shutdown command, the processor determines whether to perform a portion of bootstrapping processes of the device in response to the shutdown command before actually shutdown the device.Type: ApplicationFiled: March 29, 2013Publication date: August 29, 2013Inventors: CHI-CHANG LU, DENG-RUNG LIU

Patent number: 8331514Abstract: A method for performing a clock and data recovery includes providing data and a clock; determining early/late values of the data to generate a first-order phase code using the data and the clock; and accumulating first-order phase codes retrieved from different finite state machine (FSM) cycles to generate a second-order phase code. A plurality of candidate total phase codes is generated from the second-order phase code. A multiplexing is performed to the plurality of candidate total phase codes to output one of the plurality of candidate total phase codes as a total phase code. The multiplexing is controlled by the first-order phase code. A brake machine may be implemented to prevent over-compensation of phases.Type: GrantFiled: April 16, 2010Date of Patent: December 11, 2012Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chin-Ming Fu, Tsung-Hsin Yu, Chi-Chang Lu, Wei Chih Chen
