Patent number: 10073197Abstract: An autofocus lens system includes no conventional moving parts and has excellent speed and low power consumption. The system includes a small electronically-controlled focusing-module lens. The focusing-module lens includes two adjustable polymeric surfaces (e.g., two adjustable-surface lenses in a back-to-back configuration). The curvature of the surfaces can be adjusted to change focus. The performance of the autofocus lens system is extended by adding a conventional first and second lens, or lens group, on either side of the focusing-module lens. What results is an autofocus lens system with excellent near field and far field performance.Type: GrantFiled: February 23, 2017Date of Patent: September 11, 2018Assignee: Hand Held Products, Inc.Inventors: H. Sprague Ackley, Alain Gillet

Publication number: 20180100733Abstract: An optical pattern projector used for projecting a structured-light pattern onto an object for dimensioning is presented. The optical pattern projector utilizes a laser array, a lenslet array, a lens, and a diffractive optical element to create a repeated pattern of projected dots. The pattern repetition is based on the grid pattern of laser array. Each laser's collimated beam, when projected through the lens, impinges on the diffractive optical element from a slightly different direction. The diffractive optical element creates a sub-patterns that continue propagating along these different directions and combine on a target to produce a repeating optical pattern.Type: ApplicationFiled: December 11, 2017Publication date: April 12, 2018Inventors: Serge Thuries, Alain Gillet, Bernard Puybras

Patent number: 9891612Abstract: A system is described for positioning a load in of multiple positions disposed over a linear axis. A linear actuator moves the load into each of the positions. A first position is at an end of the movement, with a second position opposite. A third position is intermediate between the first and the second positions. A stop actuator is made of a configurable material switchable selectively between an engaged configuration, in which the load is positioned in the at least third position, and a disengaged configuration, in which the load is freely movable between the first and the second positions.Type: GrantFiled: May 5, 2015Date of Patent: February 13, 2018Assignee: Hand Held Products, Inc.Inventors: Anthony Raymond Charpentier, Alain Gillet

Patent number: 9672398Abstract: A scanner system is operable for gathering graphic data from a scan target. The scanner system has a single illumination source component operable for generating light, for aiming the scanner system with a filtered beam of the generated light directed at the scan target, and for illuminating the scan target with the directed light. The scanner system also has a detector component operable for sensing a reflection from the scan target, the sensed reflection including a portion of the directed light with which the scan target is illuminated, and for detecting information in the sensed reflection, in which the information detected in sensed reflection corresponds to the graphic data gathered from the scan target.Type: GrantFiled: October 13, 2015Date of Patent: June 6, 2017Assignee: Intermec IP CorporationInventors: Alain Gillet, Serge Thuries

Patent number: 9557166Abstract: A system and method for measuring an item's dimensions using a time-of-flight dimensioning system is disclosed. The system and method mitigate multipath distortion and improve the accuracy of the measurements, especially in a mobile environment. To mitigate the multipath distortion, an imager captures an image of an item of interest. This image is processed to determine an illumination region corresponding item-of-interest's size, shape, and position. Using this information, an adjustable aperture's size, shape, and position are controlled so the light beam used in the time-of-flight analysis substantially illuminates the illumination region without first being reflected.Type: GrantFiled: October 21, 2014Date of Patent: January 31, 2017Assignee: Hand Held Products, Inc.Inventors: Serge Thuries, Alain Gillet, Franck Laffargue

Patent number: 9400906Abstract: Machine-readable symbol readers and/or scan engines may subtractively impose an aiming pattern on an illumination field produced by a source of light or illumination. An optical component with a mask or filter are interposed in an optical path extending outwardly from the source of light or illumination. The mask or filter may have a defined shape or configuration to subtractively produce an aiming pattern with a desired shape or configuration. The mask or filter may, or may not, be wavelength selective or spectral. A wavelength selective mask or filter may produce an aiming pattern of a defined color, different from a color of an illumination field. Such may eliminate the need for a separate, distinct source of light or illumination for an aiming beam subsystem. The described structures and methods may reduce size, reduce parts count, and/or simplify manufacture.Type: GrantFiled: August 21, 2014Date of Patent: July 26, 2016Assignee: Intermec IP Corp.Inventors: Serge Thuries, Alain Gillet
