Title: Disc drive unit
Inventor: KONDO MASAMICHI
IPC: G11B19/04
Filed: 2000-04-27
Granted: 2002-12-21
Abstract: There is provided a disk drive unit which is capable of making control corresponding to contaminant and defect by discriminating the contaminant (dust, scratch) on the disk surface from the defect on the recording plane. In a pull-in signal PI corresponding to reflected light from a disk, a defect detecting signal corresponding to a signal whose level change is relatively quick corresponding to the defect of the recording plane and a contaminant detecting signal which corresponds to a signal whose level change is relatively slow corresponding to the contaminant on the disk surface are generated. When the defect detecting signal is at low level for example, a system controller retries a recording operation or increases laser light when the contaminant detecting signal is at low level. A quantity of output light of a laser diode is controlled so that a product of output light of a laser diode and reflected light from the disk amounts to a predetermined level.

Title: Dynamic range compressor-limiter and low-level-expander with look-ahead for maximizing and stabilizing voice level in telecommunication applications
Inventor: SHASHOUA MEIR
IPC: H03G7/00
Filed: 2000-05-31
Granted: 2002-02-21
Abstract: A voice signal processing system with multiple parallel control paths, each of which address different problems, such as the high peak-to-RMS signal ratios characteristic of speech, wide variations in RMS speech levels, and high background noise levels. Different families of input-output control curves are used simultaneously to achieve efficient peak limiting and dynamic range compression as well as low-level dynamic expansion to prevent excessive amplification of background noise. In addition, a delay in the audio path relative to the control path makes it possible to employ an effective look-ahead in the control path, with FIR filtering smoothing-matched to the look-ahead. Digital domain peak interpolators are used for estimating the peaks of the input signal in the continuous time domain.

Filed: 2000-07-14
Granted: 2002-02-11
Abstract: This invention is a method and device for detecting and processing crash of computer systems which uses BIOS to generate a pulse signal through the GPIO connector in steady time for the micro controller to know that the computer system does not crash when detecting the signal. If the micro controller does not detect the detecting signal in steady time, it generates a pulse signal simulated as pressing the power key and turns off the system by controlling chipsets. The micro controller re-generates the pulse signal to turn on the system after a short period of time. If the micro controller detects the system but starts the system, it will retry several times, and lights the LED for error message if it still cannot start the system. Besides, it also lights the LED if the micro controller detects that the system is on but still does not detect the pulse signal transmitted from the GPIO connector.

Title: Light guide plate, surface light source device and display device
Inventor: OHKAWA SHINGO
IPC: F21V8/00
Filed: 2001-03-29
Granted: 2005-11-01
Abstract: The present invention provides a light guide plate, surface light source device and display device which is capable of controlling a three-dimensional emission direction and avoiding fine unevenness in brightness from appearing. Light guide plate 30 has a back face 34 provided with a great number of micro-reflectors 90 each of which has a guiding portion and a conversion output portion including a valley getting narrower and shallower as being distant from the guiding portion. The conversion output portion reflects input light P twice at inner slopes to produce inner output light Q. Inner output light Q is inner-incident to a slope of projection raw PR. While some of the inner incident light becomes directly escaping light, some other of the inner incident light fails to escape directly, reaching emission face 33 after travelling further along various light paths. Indirectly escaping light is emitted at second or later chances of emission. Directly escaping light and indirectly escaping light overlap, thereby preventing fine unevenness in brightness from appearing. It is advantageous to dispose reflector RF for increasing indirectly escaping light.

Title: Method and apparatus for measuring motor torque
Inventor: TSENG YU-KUANG
IPC: H02K7/14
Filed: 2001-04-30
Granted: 2003-01-11
Abstract: A method and apparatus for measuring motor torque, especially for which applied to the mass production line, is described. The motor under testing is accelerated from the zero speed to the no-load speed by applying a constant voltage source. A reactive torque, which is equal to the motor torque, reacts on the motor stator during the acceleration process. The reactive torque is transmitted to the active torque meter containing a voice coil motor by a virtual-axis torque transmission mechanism consisting of a swing box, plural bearings, and an arm. To prevent the swing box from rotation, a balance torque equal to the reactive torque is applied, which is developed by the force of the voice coil motor and the arm. The force of the active torque meter is controlled by a position controller to apply an adequate current to the moving coil. The torque vs. speed curve is obtained by high-speed sampling the values of the current and the related speed.

Title: Gain calibration device and method for differential push-pull tracking error signal
Inventor: WU WEN-YI
IPC: G11B7/09
Filed: 2001-05-15
Granted: 2002-11-01
Abstract: The present invention provides a gain calibration device and method for differential push-pull (DPP) tracking error signal. This gain calibration is provided to process the SPPG of sub-beam to main beam in the DPP tracking error signal. The calibration theory is to control the objective lens of a pick-up head (PUH) to cause a lens-shift or control the tilted degree of the objective lens to the compact disk, so that the synthesized DPP tracking error signal generates a signal variance corresponding to the variance of the optical path. The calibrated SPPG minimizes the change of this signal, and thus the calibrated SPPG is an optimal value. In accordance with the method and device, it is able to precisely determine an optimal SPPG of the sub-beam without having to assume that two sub-beams have the same strength and are symmetric in position with respect to a main beam, and without having to know the distance between the two sub-beams and the ratio of the track distances.
