Abstract: A patterned light emitting diode device includes a layer of light emitting material between an anode and a cathode. Further, a light-reflective layer is visible through a light-emission window of the patterned light emitting diode device. The light-reflective layer includes a pattern formed by local deformations of the light-reflective layer. The pattern may be generated via impinging condensed light beam which may enter via a rear-wall of the light-reflective layer, or via impinging the condensed light beam through the light-emission window on the light-reflective layer. The deformations may be generated without significantly altering the conductivity of the light-reflective layer. An effect of this patterned light emitting diode device is that the pattern remains clearly visible both during an on-state and during an off-state of the light emitting diode device.

Abstract: A set of images (IM 1 a, IM2a, IMFa) that have successively been captured comprises a plurality of images (IM 1 a, IM2a) that have been captured under substantially similar light conditions, and an image (IMFa) that has been captured under substantially different light conditions (FLSH). For example, two images may be captured with ambient light and one with flashlight. A motion indication (MV) is derived (ST6) from at least two images (IM Ia, IM2a) that have been captured under substantially similar light conditions. The image (IMFa) that has been captured under substantially different light conditions is processed (ST7, ST8) on the basis of the motion indication (MV) derived from the at least two images (IM1 a, IM2a) that have been captured under substantially similar light conditions.

Abstract: A method and device for controlling disc run out in an optical disc drive system. The drive has a rotatable axle (7) and holding means (6) for holding a disc (2, 136) so that the normal of the disc is essentially parallel to the axle. A tilt mechanism is arranged at the holding means for tilting the disc. A collection unit (10) is arranged at the optical disc drive for reading information from or writing information to the disc. A servo means (132) maintains the collection unit at a distance (133) from the disc. The servo means generates a control signal (134) provided to an actuator (130) for lenses in the collection unit. The control signal has a DC component and an AC component having a periodicity corresponding to the rotational speed of the disk and an amplitude related to the distance. The control signal is fed to the tilt mechanism. The tilt mechanism is adjusted in an X-direction and a Y-direction for minimizing the amplitude of the control signal.

Abstract: A system for generating a quality indicator for a trellis decoded signal based on the path metrics of the decoding is presented. An apparatus comprises a path metric processor (105) which determines path metric differences between two path metrics entering a state of a trellis decoder 103. A measured distribution processor (107) orders the path difference metrics to generate a measured distribution. An analysis distribution processor (109) fits a distribution being the sum of a first and second distribution path to the measured distribution. A quality indicator processor (111) determines a quality indicator in response to the fitted distribution. In particular, the first distribution may be associated with correct sign path metric differences and the second distribution may be associated with incorrect sign path metric differences.

Abstract: The present invention relates to a method and apparatus for controlling at least one readout parameter of a magneto-optical domain expansion recording medium. An average detected runlength of the reading signal is monitored, and an error signal is generated on the basis of a comparison of the monitoring result with the predetermined average runlength that has been set during the encoding step. The at least one readout parameter is then controlled by means of the generated error signal. Furthermore, the present invention relates to a method, apparatus and record carrier wherein a runlength constraint is applied to at least one of the following quantities: mark regions and space regions in said storage layer, said runlength constraint being selected to keep an accumulated runlength deviation from a predetermined average runlength within a predetermined range.

Abstract: A disk drive comprises a turning mechanism (3 to 8) adapted to provide a pulse to the side of the disk (D) resting on a tray (2) in a position outside the center so as to provide an upward and rotating movement to the disk in order to turn it over. The turning mechanism may include a pulse member (3) acting directly on the disk. In an embodiment, the turning mechanism is pneumatic, the pulse member being a nozzle adapted to direct a pressurized gas pulse at the disk. Tests have shown that exerting an eccentric pulse on the disk results in flipping the disk over reliably and quickly.
