| 20080204621 | Tiltable LCD holder - A tiltable LCD holder comprises a base, a fixing device and at least one support device. The base has a platform on an upper end thereof. The fixing device has holes for being fixed on the platform of the base. The fixing device has two upward bended ends having a respective screw hole for screwing a respective screw bolt thereinto. The support device is connected to an object by one end thereof. The support device has screw holes on the other end for being movably coupled with the screw holes formed on the upward bended ends of the fixing device, whereby the object can be tiltable over a wide angle range to provide a steadily positioned visual angle. | 08-28-2008 |
| 20080244731 | Thin client computer with fingerprint identification structure - A thin client computer with a fingerprint identification structure of the present invention comprises a motherboard, a case, a faceplate and a fingerprint reader. The case is designed for holding the motherboard. The faceplate is placed to cover the case. The faceplate has a coupling hole on a lateral surface. The fingerprint reader is coupled into the coupling hole on the lateral surface of the faceplate, and connected with the motherboard for reading a fingerprint. The fingerprint reader is located on the lateral surface of faceplate in such a manner that the thin client computer can read the fingerprint easily no matter whether the thin client computer is placed horizontally or vertically. After verifying the fingerprint, the user is authorized to boot up or shut down the thin client computer. | 10-02-2008 |

| 20090237150 | BANDGAP REFERENCE CIRCUIT WITH LOW OPERATING VOLTAGE - A bandgap reference circuit comprising a current mirror, an operational amplifier, first and second BJT transistors is disclosed. The current mirror comprises a first input terminal, a second input terminal and at least one output terminal. The operational amplifier is coupled to the current mirror, wherein a first transistor and a second transistor respectively coupled to the first and the second input terminals have a zero or near zero threshold voltage. The first and second BJT transistors are coupled to two input terminals of the operational amplifier respectively, wherein at least one of the first and second BJT transistors is coupled to the output terminal of the current mirror through a conductive path. | 09-24-2009 |
| 20100027394 | SERVO CALIBRATION MARK DETECTION CIRCUIT FOR HD-DVD OR DVD-RAM AND METHOD THEREOF - The invention provides a servo calibration mark detection circuit for use in an optical disk drive. In one embodiment, the servo calibration mark detection circuit comprises a summing processor, a slicing level generator, and a comparator. The summing processor sums an intensity of a light beam reflected from both an inner groove and an outer groove to obtain a first signal. The slicing level generator generates a slicing level. The comparator then compares the first signal with the slicing level to obtain a second signal, wherein the second signal indicates a first location of a first servo calibration mark recorded on the inner groove and a second location of a second servo calibration mark recorded on the outer groove. | 02-04-2010 |
