摘要： A method and system communicates payload data over a plurality of low voltage differential signaling (LVDS) channels (50). First device (100) transmits the payload data and synchronization information to the second device (150) over N LVDS channels (50), along with a word clock synchronized to the payload data. The second device generates M LVDS receive clocks from the word clock, each having a same frequency that is P times a frequency of the word clock, and each having a different phase. Each of N LVDS receivers (160) of the second device (150): correlates the synchronization data with a reference word using each of the M LVDS receive clocks to produce a correlation value for each of the M LVDS receive clocks; selects a selected LVDS receive clock producing a greatest correlation value; and receives the payload data for the corresponding LVDS channel (50) using the selected LVDS receive clock.

摘要： A record carrier is described with an optically readable trackwise-arranged information structure, and an apparatus for reading said carrier. The distances between the tracks of the information structure vary so that by projecting, in addition to a read spot, at least one address spot to the information structure of a size such that is spans a number of tracks approximately equal the quotient of the average track distance and the amplitude of the track distance variation, the read spot can be rapidly addressed to a specific group of tracks. This is done with the aid of two detectors which are disposed in the path of the address-beam radiation which is diffracted in a first order by the information structure in a direction transverse to the track direction.

摘要： A digital image projector includes an illumination-light source lamp and illumination beam forming optics for forming a white-spectrum illumination beam and color-band-separation optics to divide the illumination beam into color-component subbeams. The digital image projector also includes a reflective digital-image-encoding polarization modulator mechanism such as a reflective liquid crystal display polarization modulator to reflectively modulate the linearly polarized subbeams to form color-component image encoded-polarization subbeams and projection lens optics for projecting a color image divided from the image encoded-polarization subbeams. The digital image projector further includes a plate-supported, surface mounted fixed polarization-axis polarizing beamsplitter such as a wire-grid polarizing beamsplitter for dividing the color image from the image-encoded-polarization subbeams in which a polarizer support plate of the polarizing beamsplitter faces an illumination-source side of the optical system of the projector.

摘要： Apparatus for reading a disc-shaped record carrier in which video and/or audio information is recorded in a preferably spiral track. This information is optically read by means of a beam of radiation which via a reflecting element transmits the information present in the scanned point of the record carrier to a read detector. The radial position of the scanning point is controlled by controlling the angular position of the reflecting element which for this purpose is included in a control loop. In order to reproduce the information at a speed different from the recording speed, for example to display slow-motion pictures or still pictures, the reflecting element may be subjected by means of a control signal to an abrupt change in angular position so that the scanning point undergoes an abrupt radial displacement. This displacement preferably takes place during the frame flyback periods of the video information.

摘要： A prism is mounted onto a motor without regard to its rotation angle relative to the motor index. Its position is electronically set later after construction of the optical path. A motor controller is used to control the rotation of the prism. This motor controller keeps the prism spinning at a constant velocity and positions the prism phase (rotation angle versus time). A variable offset is used to position the absolute prism rotation as a function of time. The phase may be advanced or delayed by an operator during set up. Each prism has its own phase. The phase of each prism in the system is set so that the illumination pattern correctly matches the video addressing of the panel. This is a one time set up during construction. The correct positions are set, and stored in non-volatile memory for life.

摘要： A scanner phase control for a scrolling color projector utilizes the back-EMF value of a motor which rotates a prism of the scanner to set a reference point for the prism. A reference phase signal is provided which corresponds to timing information of the scan of a stripe of light provided by the prism. The phase of the motor is altered in response to the reference phase signal such that the back-EMF zero crossings of the motor coincide with the beginning of a scan as identified by the reference phase signal.
