  • Patent number: 10863492
    Abstract: Methods, systems, and devices for wireless communication using various patterns of data and reference signals are described. For example, in a system that supports operation using different duration transmission time intervals (TTIs), a base station may initiate communication with a user equipment (UE) or between two UEs, and UEs may communicate with the base station or with one another using an indicated pattern of data and reference signals. The base station may send a downlink control message indicating a transmission pattern selected from a set of patterns. UEs may identify the pattern based on the indicator and decode a sequence of data and reference signals based on the pattern. In some examples, the sequence may include a set of TTIs, which may have a shorter duration than other TTIs.

  • Patent number: 10481381
    Abstract: An object of the present invention is to widen a range in which line of sight change is possible, particularly in a pan direction. According to the present invention it is possible to acquire high line of sight changing speed. A pan mirror is capable of rotation in forward and reverse directions about a third rotational axis. Also, the third rotational axis extends in a direction that is substantially parallel to a line of sight direction directed from a tilt direction control section to the pan mirror. An angle ? formed by the pan mirror and the third rotational axis is set in a range 0°<?<90°. The tilt direction control section can scan line of sight direction with respect to a virtual plane formed by a rotation locus of the pan mirror. The tilt direction control section can also control tilt angle of the line of sight direction from the pan mirror to a physical object.

    Abstract: A scanning optical system, includes a mirror unit having a first mirror surface and a second mirror surface which incline to a rotation axis; and a light projecting system having a light source. A light flux emitted from the light source is reflected on the first mirror surface of the mirror unit, thereafter, reflected on the second mirror surface, and then, projected so as to scan in a main scanning direction onto an object in accordance with rotation of the mirror unit. In the case where a virtual plane is set in a range including the object, a light flux reflected on the second mirror surface has, upon entering the virtual plane, a cross sectional shape in which a length in a direction orthogonal to the main scanning direction is longer than a length in the main scanning direction.

  • Patent number: 8434686
    Abstract: This invention provides a point-of-sale scanning device that employs vision sensors and vision processing to decode symbology and matrices of information of objects, documents and other substrates as such objects are moved (swiped) through the field-of-view of the scanning device's window. The scanning device defines a form factor that conforms to that of a conventional laser-based point-of-sale scanning device using a housing having a plurality of mirrors, oriented generally at 45-degree angles with respect to the window's plane so as to fold the optical path, thereby allowing for an extended depth of field. The path is divided laterally so as to reach opposing lenses and image sensors, which face each other and are oriented along a lateral optical axis between sidewalls of the device. The sensors and lenses can be adapted to perform different parts of the overall vision system and/or code recognition process. The housing also provides illumination that fills the volume space.

  • Patent number: 8371507
    Abstract: A method of selectively generating one or more scan lines from a multi-scan line scanner involves measuring the pulse widths of the pulses in a signal output of a motor driving the polygon mirror of the scanner wherein the signal relates to the position of the polygon's mirror facets. By measuring and distinguishing each of the pulses in the signal, the illumination of the scan beam can be synchronized with the rotation of the polygon mirror to only generate a desired number of scan line patterns that is less than the full complement of the scan line patterns capable of being generated by the multi-scan line scanner.

    Abstract: Systems and techniques for stitching together partial bar code segments to construct and decode information for a complete bar code. As a scanner operates to generate a scan pattern, information is maintained that can be used to identify a scan line being generated when an event of interest occurs. When a scan signal indicates that a terminal delimiter of a bar code is included in a bar code segment that has been transected by a scan line, information is noted that can identify the scan line. Subsequent transections of the bar code by the same scan line are noted, and information for overlapping bar code segments is stored. When a segment is detected that includes a delimiter opposite the delimiter appearing in the original segment, the stored information is retrieved and used to assemble the complete bar code.

The laser scanning pattern of the present invention comprises plurality of groups of intersecting laser scanning planes that form a complex omni-directional 3-D laser scanning pattern within a 3-D scanning volume capable of scanning a bar code symbol located on the surface of an object presented within the 3-D scanning volume at any orientation and from any direction at the POS station so as to provide 360° of omnidirectional bar code symbol canning coverage at the POS station.

  • Patent number: 6991169
    Abstract: An optical system and method for data reading. The preferred system is directed to a scanner which includes a laser diode and a beam splitter for generating first optical beam and a second optical beam, the first optical beam being directed toward one side of a scanning optical element such as a rotating polygon mirror and to a first mirror array, the second optical beam is being simultaneously directed toward a second optical element such as another side of the rotating polygon mirror and then to a second and a third mirror array. The first mirror array is configured to generate a scan pattern through a vertical window and the second and third mirror arrays are configured to generate scan patterns passing through a horizontal window. In combination, the three mirror arrays generate three sets of scan lines so as to scan the bottom and all lateral sides of an object being passed through the scan volume.
