Abstract: A lens position signal LCE which indicates the discrepancy between the lens and its geometric mid-position is required for coarse tracking of optical storage drives. The prior art is for the lens position signal LCE to be formed in three-beam pick-ups by weighted combination of specific photodetector signals from a primary beam and secondary beam. The only way to ensure that the lens position signal is free of crosstalk caused by the tracking error signal is for the weights to be set correctly. The invention describes methods by means of which the weights can be adjusted automatically and can be matched to the characteristics of the pick-up and of the respective storage medium. The amplitudes of those components in the main and secondary beam signals which are dependent on the tracking error are measured, and the matched weights are determined from them by joint evaluation. Evaluations with synchronous detection and with time integration are described, some of which can be used during writing and reading.

Abstract: A field sequential pulse width modulated display system comprises a digital micromirror device (DMD) having a plurality of micromirrors that each selectively pivot to reflect light onto a screen to illuminate a corresponding pixel. A driver circuit controls the DMD responsive to sequences of pulse width segments formed by a processor. The processor actuates at least one pulse in a first pulse width segment for a given color to increase pixel brightness with a range lying between first and second pixel brightness values. To further increase pixel brightness, the processor actuates at least one pulse within additional pulse width segments associated with the same given color to increase pixel brightness above the second brightness boundary. The pulses within the additional segments are actuated unequally so that the additional pulse width segments closest in time to the first segment (i.e.

Abstract: The present invention is related to a cabinet for consumer electronic devices equipped with loudspeakers. Examples for such devices are audio equipment like CD players, tape recorders, radios, and television receivers. In particular, the invention is related to devices where the loudspeakers form an integral part of it. The manufacturing of the cabinet as an integral part by injection molding of their sticks requires a molding tool for each type of cabinet. However, for marketing reasons it is necessary to be able to present a serious of one type of devices, e.g. portable audio devices distinguishing over each other in the design. This causes increased manufacturing costs due to the need for individual molding tools for each individual cabinet.

Abstract: A method and system for recording a program in an apparatus that has auxiliary programming information available are described. A program is first selected for recording. A determination is made to see whether the associated auxiliary programming information is available for the selected first program for recording. If the associated auxiliary programming information is not available for the selected first program, then a recording timer is automatically populated with all known recording parameters. All the unknown recording parameters in the recording timer are also populated according to a predetermined algorithm.

Abstract: A video decoder system collates program guide information acquired from a variety of local and remote sources. Program guide information is received from a first source and a selectable program guide menu icon is displayed. A category of program guide information items from the first source is collated by a display attribute in response to selection of the menu icon and the collated program guide information items are displayed. The display attribute allocated to the category of program guide information items is common to both the category of items and to the menu icon. Codes identifying program categories may be converted to other codes using equivalence mapping information for classifying programs according to a master set of program categories. Composite program map information may be formed including new data identifiers allocated to program guide information items for use in retrieving the items from a second source.

Abstract: The central idea of the present invention is that the resetting of the energy store associated with the receiver prior to every detection interval and/or prior to every exposure period, during which the energy stored in the energy store is to be changed in accordance with the output signal of the receiver so as to use the state of the energy store following the reception interval as information about the object may be avoided by setting the sensitivity of the receiver, which determines the level of the output signal at a specified electromagnetic radiation, higher in at least one instance, and lower in at least one instance between two resetting events, or by varying the sensitivity. The noise contribution provided by the resetting operations is hereby avoided, which is why the benefit of the accumulation and/or integration may be exploited across several reception intervals without this noise contribution.

Abstract: A method and an apparatus using a system level clocking scheme to remove jitter from multi-media packets distributed over an asynchronous network, in particular an asynchronous network. The present invention overcomes the problems associated with jitter introduced in an asynchronous network by using various time stamps to synchronize a client device clock to a headend clock and to control the data flow in the client device to match the rate that the data is received by a broadband receiver coupled to the headend. A first time stamp is prepended to the transport packets when the packets are received from the headend. A second time stamp is placed in the data frame when the data frame is placed on the network. A third time stamp is placed in the data frame when the data frame is received from the network. The second and third time stamps are used for synchronizing the client clock to the server clock, which is in turn frequency locked to the headend clock.

Abstract: Since the phosphor lag effect results from the slowness of the green and red phosphors and since it is not possible to make these phosphors faster, the blue one has to be made slower in order to reduce the color trail effect. Therefore, a part of the blue component is artificially delayed. Only a certain percentage of the blue component of the actual frame is transmitted during the actual frame, whereas the rest of the blue component will be transmitted during the next frames. The dynamic false contour effect introduced by this video processing may be compensated by subfield shifting.
