IPC: H01S5/40
Filed: 1993-12-02
Abstract: A laser multibeam printer or recorder includes a laser diode array (12) generating multiple modulated parallel and diverging light beams with predetermined light intensities at any instant of time. Optical means (16;18) reduce the divergence of the parallel light beams from the laser diode array (12) by a predetermined amount, do not focus the light beams in a first cross-section direction along a width of the laser diode array (12), and focus the light beams onto a plane of an entrance pupil (24) of a printing lens (22) in a second cross-sectional direction normal to the first cross-sectional direction. A separate lenslet (21) of a lenslet array (20) directs a corresponding light beam from the laser diode array (12) towards a predetermined area on a plane in front of the printing lens (22) (e.g.,the entrance pupil,(24)) in the first cross-sectional direction, and focuses the light beam onto the plane of the entrance pupil (24) in a second cross-sectional direction. The printing lens (22) images the light beams at the entrance pupil (24) onto a light sensitive media (27) as a corresponding array of closely-spaced spots of data with predetermined intensities. Various other arrangements using a field lens in combination with the lenslet array with or without a micro lenslet array can be used to process light beams and form an image of closely-spaced spots of light on the light sensitive media.

Abstract: A technique for modifying the IEEE 802.3 standard for selecting transmit-to-transmit interpacket gap (IPG) intervals in a Carrier Sense Multiple Access with Collision Detection (CSMA/CD) network, to provide fairness and good channel utilization in the event that a node has captured the network communication channel. If there is a small number of active nodes on the network, one node may capture the channel and the standard backoff algorithm makes it increasingly unlikely for another node to transmit. The new technique provides for use of a longer interpacket gap (IPG) interval to be used by a node that has been initially unsuccessful in contention for the channel, thereby ensuring that the other node may continue to transmit back-to-back data packets without interrruption or collision. After a preselected time interval, the nodes reverse their roles by selecting the opposite IPG intervals. The initial receiver now selects the shorter IPG interval and captures the channel for the preselected time interval.

Abstract: The present invention changes a color corresponding to a source color to a destination color by initially selecting a target source color and a target destination color. The selected target source color is converted to a source hue value, a source chroma reference value, and a source lightness reference value, and the selected target destination color is converted to a destination hue value, a destination chroma reference value, and a destination lightness reference value. A circuit then generates a first set of source/destination chroma and a first set of source/destination lightness values representing source/destination chroma and lightness relationships, respectively, for sources values in a range from the source chroma and lightness reference values, respectively, to minimum source chroma and lightness values, respectively, using a first and third function, respectively. The circuit also generates a second set of source/destination chroma values and a second set of source/destination lightness values representing source/destination chroma and lightness relationships, respectively, for source values in a range from the source chroma and lightness reference values, respectively, to maximum source chroma and lightness values, respectively, using a second and fourth function, respectively. These values are stored. Received color data is converted to a color hue value, a color chroma value, and a color lightness value. A comparator determines if the color hue value corresponds to the source hue value. When the comparator determines that the color hue value corresponds to the source hue value, destination chroma and lightness values associated with the source chroma and lightness values, respectively, that corresponds to the color chroma and lightness values, respectively, are selected based on the stored source/destination chroma and lightness relationships, respectively. The destination hue value and the selected destination chroma and lightness values are converted into output color data representing the destination color.

Abstract: A method for correcting the skew between the leading edge of a sheet (32A) of paper and the nip (75) of a roller assembly (70) in a printing mechanism (10) includes the steps of advancing a sheet (32A) of paper into the nip (75) and slightly therebeyond. The rollers (72 & 74) are then rotated in reverse, causing the paper to retract from the roller assembly (70), with the angle and weight of the paper maintaining the leading edge within the nip (75). As the rollers (72 & 74) continue to rotate backwards, the paper jiggles or dances allowing the leading edge to settle parallel with the nip (75) under its own weight. The paper is then readvanced through the roller assembly (70) with its leading edge parallel to the nip (75). A mechanism (150, 152, 162, 164, 172, 174, 182, 184, 185) applies a drag force to the paper when the paper is being retracted from the roller assembly (70) to keep the leading edge of the paper in the nip (75). 
     A single motor control apparatus includes a processor-controlled drive motor (55), a drive roller assembly (70), a pick roller assembly (60) and a gearing arrangement (40) coupling the drive motor (55) to the roller assemblies (60, 70), for selective control of the timing, speed and rotational direction thereof to achieve the above described method.

Abstract: A device to simply control a position and an amount of rotation of a carrier and to prevent a decrease of the control accuracy upon thermal expansion of the carrier.On a base (15), a carrier (16) is slidably and at the same time rotatably supported. The carrier (16) has arms (41, 42 and 43) which are driven by a respective drive element (21, 22 and 23) for each of three axes (X, X', and Y). The drive elements of each axis (21, 22, 23) are the same distance from a reference axis which functions as the center of rotation of the carrier (16). When the carrier (16) moves in the X direction, by means of the drive elements (21 and 22), two of the arms (41 and 42) are moved by the same amount. For movement in the Y direction, the third arm (43) is moved by the third of the drive elements (23). When the carrier (16) is turned, the drive elements (21, 22 and 23) move all of the arms (41, 42 and 43) the same amount in the direction in which the carrier is turned.

Abstract: A magnetic roller recorder consists of a sequence of high energy bar magnets mounted contiguously on the cylindrical surface of a roller. Depending upon the data pattern to be recorded, the sequence may consist entirely of magnets, or may consist of magnets interspersed with non-magnetic "dummy" bars in the shape of the magnets to establish the overall configuration of the desired data pattern. The direction of magnetization of each cylindrically mounted magnet is radially directed, i.e. along each magnet's thickness direction, and that the direction of magnetization of adjacent magnets be oriented at 180 degrees with respect to each of its abutting neighbors. Resultantly, each magnet's magnetization direction is perpendicular to the plane of a slave layer contacting the roller.

Abstract: The present invention provides a multi-mode CELP encoding and decoding method and device for digitized speech signals providing improvements over prior art codecs and coding methods by selectively utilizes backward prediction for the short-term predictor parameters and fixed codebook gain of a speech signal. In order to achieve these improvements, the present invention provides a coding method comprising the steps of classifying a segment of the digitized speech signal as one of a plurality of predetermined modes, determining a set of unquantized line spectral frequencies to represent the short term predictor parameters for that segment, and quantizing the determined set of unquantized line spectral frequencies using a mode-specific combination of scalar quantization and vector quantization, which utilizes backward prediction for modes with voiced speech signals. Furthermore, backward prediction is selectively applied to the fixed codebook gain in the modes that are free of transients so that it may be used in the fixed codebook search and fixed codebook gain quantization in those modes.
