Publication number: 20160070400Abstract: 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: November 16, 2015Publication date: March 10, 2016Inventors: CHENG-HAO WENG, DENG-RUNG LIU, CHI-CHANG LU

Patent number: 8995597Abstract: 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: November 16, 2012Date of Patent: March 31, 2015Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chin-Ming Fu, Tsung-Hsin Yu, Chi-Chang Lu, Wei Chih Chen

Publication number: 20150089105Abstract: An electronic computing device comprises first and second nonvolatile memories. The second nonvolatile memory serves as a main memory of the device. A processor clears the second nonvolatile memory in response to shutdown command according to a setting reflecting a first user operation. A processor clears the second nonvolatile memory and loads the kernel from the first nonvolatile memory to the second nonvolatile memory in response to a boot command according to a condition of a second user operation detected by the processor regardless of the setting reflecting the first user operation.Type: ApplicationFiled: December 3, 2014Publication date: March 26, 2015Inventors: CHI-CHANG LU, DENG-RUNG LIU

Patent number: 8935522Abstract: 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 the kernel from the first nonvolatile memory to the second nonvolatile memory in response to a boot command. When receiving an interrupt representing a shutdown command, the processor determines whether to clear the second nonvolatile memory in response to the shutdown command before actually shutting down the device.Type: GrantFiled: March 29, 2013Date of Patent: January 13, 2015Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Chi-Chang Lu, Deng-Rung Liu

Patent number: 8736553Abstract: A text input method is implemented in a device with a plurality of keys. If a first key is activated by a first touch operation, one character in a first character set associated with the first key is selected as a first character. If a second key is activated by a second touch operation one character in a second character set associated with the second key is selected as a last character. Each of the first and second touch operations includes a press, a touch track, or a combination of a press and a touch track on a key. An auto-completed word is generated based on a database of words in response to the second touch operation. The auto-completed word includes the first character as a leftmost character of the auto-completed word and the last character as a rightmost character of the auto-completed word.Type: GrantFiled: September 25, 2012Date of Patent: May 27, 2014Assignee: Gold Charm LimitedInventor: Chi-Chang Lu
