Patent number: 8033471Abstract: An optical image reader is provided. The image reader includes, for example, a targeting system for an imager, which includes a light device having a plurality of light emitting diodes (LEDs), each for emitting light, and a device for shaping a single targeting light based on the outputs of the plurality of LEDs. The image reader includes, for example, an image system for capturing image of an indicia on an object, which includes a targeting light source for providing a targeting light to the indicia on the object; and an optical system for focusing reflection from the object, having a liquid focus lens element having a variable focus, and a controller for controlling the focus of the focus lens.Type: GrantFiled: May 8, 2008Date of Patent: October 11, 2011Assignee: Psion Teklogix Inc.Inventors: Don Van Kerkhoven, Pierre Deguire, Xinjun Xie

Patent number: 7377437Abstract: A targeting system for a portable image reader, which advantageously combines a number of functions including alignment, aiming, framing and range finding and provides a wide imaging range with an optimal field of view, is described. The targeting system projects a predetermined pattern having two or more components onto the target such that the components maintain a uniform distance between one another to bound the target and further vary in size as a function of their distance between the image reader and the target. The targeting system comprises targeting LED's, apertures positioned over the targeting LED's, and cylindrical lenses positioned over the apertures. With this arrangement, at least two vertical lines are projected onto a target such that the lines maintain a uniform distance apart from one another, but vary in length as a function of the reader distance from the target. This allows the operator to quickly position the imaging device over a target.Type: GrantFiled: December 19, 2006Date of Patent: May 27, 2008Assignee: Psion Teklogix Systems Inc.Inventors: Gregg R. Kricorissian, Xinjun Xie

Patent number: 7304290Abstract: The optical image reader is versatile since it can be assembled for use in a variety of reader applications, such as an ultra high definition reader, a high definition reader, a standard reader and an ultra long range reader. In addition to a housing enclosing an image sensor, an adjustable objective lens assembly for focusing an image of a target on the image sensor and a light source for illuminating and/or targeting the target, the reader includes a light shaping optical element array comprising optical elements assembled together as an integral unit and adapted to be fixed to the housing for shaping and directing light on the target. The optical elements are mounted on a panel, which is adapted to be fixed to the reader housing either permanently, or releasably to permit replacement of the panel on the housing.Type: GrantFiled: August 27, 2004Date of Patent: December 4, 2007Assignee: Psion Teklogix Systems Inc.Inventors: Gregg Kricorissian, Xinjun Xie, Tao Zhang

Publication number: 20060087580Abstract: A camera module, having a objective lens that can be displacd to set the focal distance for a number of predetermined applications, is described. The objective lens is displaced by an electro-mechanical system. An operator selects a particular focal distance corresponding to a particular scanning application through a control interface. A current source supplies a current proportional to the selected focal distance to a solenoid. The solenoid plunger is connected to a lever that is coupled to the objective lens to move it to the selected focal distance within the camera module.Type: ApplicationFiled: October 21, 2004Publication date: April 27, 2006Inventor: Xinjun Xie
