  • Patent number: 6842250
    Abstract: The present invention relates to a device and a method for determining the quality of surface. An illuminating light source radiates light at a predetermined angle onto the measurement surface. An optical detecting device receives the light reflected from said measurement surface and converts same into an electrical measurement signal. A processor controls the measurement sequence and evaluates the measurement results, which are emitted via an output device. The illuminating light source comprises at least one light-emitting diode. The light emitted comprises at least blue, green and red spectral components in the visible range of the spectrum. A filter is provided in the path of radiation between the light source and the photosensor.

  • Patent number: 6795387
    Abstract: A method for controlling the rotational speed of a disk player includes first calculating the proportion of time which the disk player is reading data from the disk during a unit time T. Thereafter, the method increases the rotational speed of the disk player if the proportion of time that the disk player spends reading data from the disk is greater than a first threshold during each of m consecutive units of time T, and decreases the rotational speed of the disk player if the proportion of time that the disk player spends reading data from the disk is less than a second threshold during each of n consecutive units of time T.

  • Patent number: 6773275
    Abstract: A memory card connector is positioned on a printed circuit board (PCB) which is coupled to ground so as to receive and couple a memory card. The connector has a main body positioned on the PCB. The connector also has a cover removably attached to the main body to define a memory card receiving space between the PCB, the main body and the cover. The cover has at least one flexible extension extending into the receiving space, and a draining portion that is electrically coupled to the main body. The memory card is inserted into the receiving space so that the extension contacts a metal portion on the memory card, with the extension electrically coupled to ground via the draining portion and the main body. Thus, static electricity can be drained to ground via the extension, the draining portion and the main body.
