Publication number: 20140111996Abstract: A lamp apparatus include a lamp body, at least an alternating current light-emitting diode and a plug. The alternating current light-emitting diode is disposed on a lamp body. The plug is electrically connected to the alternating current light-emitting diode. In lamp apparatuses utilizing AC LED, heat generated thereby is almost concentrated on chips. Compared with conventional lamp apparatuses utilizing DC LEDs, heat generated thereby is distributed on chips and outer rectifier. In lamp apparatuses utilizing AC LEDs, heat generated thereby is almost concentrated on chips because AC LEDs operate directly with AC electric power, omitting a rectifier and preventing power loss during operation of power rectification. Therefore, the heat accumulated on the chips of the AC LEDs is enough to be used to evaporate essential oil. In another embodiment, the invention utilizes low-resistance pure water surrounding the AC LED to dissipate its heat.Type: ApplicationFiled: January 2, 2014Publication date: April 24, 2014Applicant: Epistar CorporationInventors: Wen-Yung YEH, Jui-Ying LIN, Yu-Chen YU, Yu-Chun LIN, Ta-Wei CHIEN, Ming-Te LIN, Yu-Chun LIN

Patent number: 8675724Abstract: A method for updating a tap coefficient of a decision feedback equalizer is provided. The method includes sampling a first input signal received by a sampler of a decision feedback equalizer. It is determined if an amplitude of the first input signal falls within a range defined between a first predetermined voltage level and a second predetermined voltage level. If the amplitude of the first input signal falls outside the range, a tap coefficient is updated to generate an updated tap coefficient that is fed back to adjust an amplitude of a second input signal received at an input end of the decision feedback equalizer. If the amplitude of the first input signal falls within the range, the tap coefficient is free from being updated.Type: GrantFiled: July 15, 2010Date of Patent: March 18, 2014Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Yung-Chow Peng, Yu-Chun Lin

Patent number: 8411542Abstract: A method for controlling layer changes for an optical disk drive is provided, where a focus of a laserbeam emitted by a pickup head of the optical disk drive is moved from a current data layer of a disk to a target data layer of the disk. First, a position of a collimator lens of the pickup head is adjusted for spherical aberration correction. The objective lens is then lowered to a low position to move the focus of the laserbeam off the surface of the disk. The objective lens is then raised towards the disk. A focusing error signal is generated while the objective lens is being raised. Whether a target S-curve corresponding to the target data layer is present in the focusing error signal is then started to be detected. If the target S-curve is detected, the focus on operation on the target data layer of the disk is successful.Type: GrantFiled: March 14, 2008Date of Patent: April 2, 2013Assignee: Mediatek, Inc.Inventors: Kun-Yi Chan, Yu-Chun Lin, Ying-Feng Huang
