  • Patent number: 9853575
    Abstract: A linear actuator assembly has a linear actuator including a motor shaft extending from a base with a piezoelectric component oscillate the shaft. The shaft has a faceted surface. A movable carriage has a notch with at least one flat surface that receives the shaft of the linear actuator. The carriage is in direct and continuous contact with the motor shaft at the notch such that the motor shaft's facet is in contact with the flat surface of the notch, when the carriage moves linearly along a travel axis. A spring is coupled to the carriage to urge the motor shaft into contact with the notch of the carriage so as to maintain contact between the motor shaft facet and the flat surface of the notch to inhibit rotation of the motor shaft.

  • Patent number: 9033242
    Abstract: A device permitting multiple focusable fields of view, such as a universal bar code scanner that can read bar code symbols at both near and far distances for a range of X-dimensions, is described. The scanner uses an adjustable optical imaging system that has at least two different focused fields of view. In one embodiment, the optimal field of view for a target object can be automatically selected with the use of a range finder.

  • Patent number: 7967206
    Abstract: An automatic data collection device is provided for reading barcodes, matrix codes, stacked codes, or other machine-readable symbol. The data collection device generates an aiming beam that serves a dual purpose of target locating and data acquisition, such as data acquisition using imaging methods. The aiming beam defines the field of view of the data collection device for imaging. The illumination pattern provided by the aiming beam for imaging can have its shape, size, and/or intensity adaptively changed depending on conditions.

  • Patent number: 7950581
    Abstract: A system and method for acquiring a machine-readable symbol are disclosed. Briefly described, one embodiment comprises receiving at least one scan line of a codeword row, determining a number of codewords of the codeword row, and collapsing an initialization symbol matrix into a partially-collapsed machine-readable symbol matrix based upon the determined number of codewords. Once the number of rows in the machine-readable symbol are determined, the partially collapsed machine-readable symbol matrix is further collapsed to the determined number of codeword rows.

  • Patent number: 7413125
    Abstract: The invention relates to a device and a process for acquiring bichromatic bar codes, with a two-dimensional sensor with electronic scanning. The height Hy of the scanned portion is modified between at least two successive scanning operations. Thus, the device is or may be adapted to the type and/or to characteristics not known in advance of the code to be read.

  • Patent number: 7412097
    Abstract: A process for detection of straight-line segments in a stream of digital data that are representative of an image (m, n) in which the contour points of said image each defined by the modulus and the orientation ? of their gradient in relation to a horizontal axis are identified. The stream of digital data is stored in the form of two successive lines, each of n points P(i, j), for each of the lines the n points of said line are extracted successively, and for each point Pc(i, j) extracted, the so-called current point, the three points having inferior coordinates Pa(i?l, j?l), Pb(i, j?l), Pd(i?l, j) directly neighbouring said current point are extracted, successively the value of the orientation of the current point Pc is compared with that of the neighbouring points Pa, Pb and Pd. The values of the orientations of the points Pb and Pd are compared, the result of a comparison is validated if the points are contour points and if the values of their orientation are close.

  • Publication number: 20070295817
    Abstract: An automatic data collection device, such as a scanner-type device, is provided with a deformable mirror that operates in conjunction with a scanning mirror to scan a target machine-readable symbol using a scanning beam. The deformable mirror includes a reflective membrane having a shape that can be changed by applying electric charge to conductors, or by some other type of actuation. In this manner, the focus distance, depth of field, wavefront shape, or other property of the scanning beam can be changed dynamically. Feedback information can be provided to a focus control algorithm to control adjustment of the deformable mirror so as to optimize the scanning.

  • Patent number: 6435411
    Abstract: An optoelectronic device for acquisition of images of objects, such as barcodes, includes a lighting system which is designed such that the axis of the light beam intersects the optical axis. A reflector that allows the image beam to pass through, and can reflect the light beam, is disposed such as to intercept the light beam, and is inclined relative to the optical axis, by an angle which is such that the light beam is centered on the optical axis. The lighting system is designed to light the useful optical field throughout the entire depth of the field, and the angle &agr;, in which the lighting system is seen from the object plane, is such that α ≤ Arc ⁢   ⁢ tg ⁢ L 5 ⁢ P , in which L is the width of the object plane, and P is the distance between the object and the lighting system.
