Patent number: 8681113Abstract: An all-in-one computer system comprising: a base panel having a top surface and a bottom surface; and a screen panel coupled to and extending from the base panel, the screen panel comprising a screen. In some embodiments, a speaker system is coupled to the bottom surface of the base panel to provide a stand on which the base panel can be supported at an angle with respect to a resting surface, wherein the speaker system is configured to be adjusted along the bottom surface of the base panel to adjust the angle at which the base panel is supported. In some embodiments, a processing unit is communicatively coupled to the tilt sensor and to the screen, wherein the processing unit is configured to switch the screen between a touch mode and a non-touch mode based on the angle sensed by the tilt sensor.Type: GrantFiled: September 27, 2011Date of Patent: March 25, 2014Assignee: Flextronics AP, LLCInventors: Chun-Ting Wu, Chen-Pang Chuang, Wen-Chung Wu, Chu-Wei Yang

Patent number: 6949899Abstract: A brushless dc motor includes a conversion circuit and a dc motor drive circuit. The conversion circuit includes a rectifier unit, a pulse-wave-absorbing unit, a filter unit, a voltage-stabilizing control unit and a voltage-stabilizing unit. The rectifier unit, the pulse-wave-absorbing unit and the filter unit are serially connected between an ac power source and the dc motor drive circuit. The ac power source is rectified, stabilized and filtered to thereby supply with a dc voltage to the dc motor drive circuit. The voltage-stabilizing control unit and the voltage-stabilizing unit are serially connected between the rectifier unit and the dc motor drive circuit so as to limit a passage of a high voltage and to allow a passage of a low voltage through the dc motor drive circuit. Thereby, the voltage-stabilizing control unit and the voltage-stabilizing unit are commonly in control of the operation of the dc motor drive circuit.Type: GrantFiled: July 22, 2003Date of Patent: September 27, 2005Assignee: Sunonwealth Electric Machine Industry Co., Ltd.Inventors: Alex Horng, Wen-Chung Wu, Chung-Ken Cheng

Publication number: 20030152166Abstract: Methods and circuits utilizing a two stage adaptation algorithm to determine the optimal code for an equalizer to compensate a received signal is disclosed. In the first stage, a coarse tuning algorithm is used to choose a range of codes based on the amplitude of the received signal. The chosen codes will be used as reference points in the second stage. In the second stage, a fine tuning algorithm is used to select a code in the range of reference codes determined in stage one. The fine tuning algorithm looks to the status of the data lock signal generated by the clock recovery circuit. If the data lock signal does not indicate a lock, the fine tuning algorithm cycles through the range of reference codes. If the data lock signal indicates a lock, then that particular code is continued to be used for the equalizer.Type: ApplicationFiled: March 10, 2003Publication date: August 14, 2003Applicant: Altima Communications CorporationInventors: Xi Chen, Bao Lenguyen, Wen-Chung Wu

Patent number: 6242961Abstract: Circuits for the restoration of a drooped signal are disclosed. In the asynchronous mode circuit, the drooped signal can be restored by detecting the peak of the positive amplitude and the peak of the negative amplitude and take the difference between the two peaks. This difference signal is fed back the equalizer. In the synchronous mode circuit, the drooped signal is sliced and passed to a regeneration circuit. The regeneration circuit uses reference voltage signals and phase information from the slicer to generate a regenerated signal. The regenerated signal is compared with the equalized signal to generate a difference signal, again fed back to the equalizer. The sliced signal is also fed to a clock recovery circuit which recovers the clock signal embedded in the received signal. The two circuits can be combined to provide an optimal circuit for the restoration of a drooped signal.Type: GrantFiled: October 8, 1999Date of Patent: June 5, 2001Assignee: Altima Communication, Inc.Inventors: James Liu, Wen Fang, Wen-Chung Wu
