Publication number: 20020191830Abstract: The present invention is an improved indicia reader which, in addition to having magnetically encoded information reading capabilities in one embodiment, includes image sensing capabilities. A compact housing is provided which receives an indicia bearing member. Mounted on the housing in one embodiment are an imaging assembly, and a magnetically encoded information reader, which form an indicia-determining unit, and a transport mechanism for transporting the indicia-determining unit and a received member relative to one another. The reader may further includes a data format engine in communication with the indicia-determining unit.Type: ApplicationFiled: July 29, 2002Publication date: December 19, 2002Applicant: Welch Allyn Data Collection, Inc.Inventors: John M. Pidhirny, Kevin R. Jost, Thomas D. Britton, John L. Casey

Patent number: 6473519Abstract: The present invention is an improved check reader which, in addition to having magnetic ink character recognition capabilities, includes image sensing capabilities. A compact housing is provided which receives a document. Mounted on the housing are an imaging assembly, and a magnetic ink character reader, which form an indicia-determining unit, and a transport mechanism for transporting the indicia-determining unit and a received document relative to one another. The check reader further includes a data format engine in communication with the indicia-determining unit. When a document and the indicia-determining unit are transported relative to one another, the data-format engine captures a first electronic representation of indicia formed on the received document, and a second electronic representation of magnetic ink indicia on the received document.Type: GrantFiled: February 21, 1996Date of Patent: October 29, 2002Assignee: Hand Held Products, Inc.Inventors: John M. Pidhirny, Kevin R. Jost, Thomas D. Britton, John L. Casey

Patent number: 6060722Abstract: An optical assembly for use with optoelectronic readers. An imaging optical assembly having an imaging optical axis forms an image of a two-dimensional region on an optoelectronic imaging device. An aiming pattern generator including at least a point-like aiming light source and an interferometric pattern generating optical element project onto the two-dimensional region a luminous aiming pattern that approximately coincides with the field of view of the imaging device. The aiming optical axis of the aiming pattern remains approximately coincident with the field of view of the imaging device over the range of reader-to-target distances over which the reader is used.Type: GrantFiled: September 24, 1997Date of Patent: May 9, 2000Inventors: William H. Havens, John M. Pidhirny, Robert J. Hennick

Patent number: 6045047Abstract: An optical reader is suitable for reading 2-dimensional indicia. The optical reading device, that may include a bar code reader, comprises a guide whose length along the optical reader optical axis is such that when that guide contacts the part or equipment surrounding the indicia to be read, that indicia is within the optical reader depth of field. The reader comprises a housing having therein a source of illumination and optics for producing a diverging beam for illuminating indica. A spacing element transparent guide is removably attached to the housing, and does not block indicia. The line of contact of the guide with the data carrier is substantially fully visible to the operator, who can thus confirm that the guide is in proper operating position relative to the indica prior to initiating a reading operation. A reading operation can be initiated by pressing on the guide to actuate a switch, or on a manual trigger.Type: GrantFiled: June 19, 1998Date of Patent: April 4, 2000Assignee: Welch Allyn Data Collection, Inc.Inventors: John M. Pidhirny, Richard A. Monroe, Michael J. Pileski, Robert J. Wood

Patent number: 5786586Abstract: An optical reader is suitable for reading 2-dimensional indicia. The optical reading device, that may include a bar code reader, comprises a lens assembly and a guide detachably mounted on a front portion of the housing for establishing a distance between the lens assembly and an equipment target that is displaced a predetermined distance from a mark target wherein the optical reader further comprises an attaching member for supporting the lens assembly on the guide to form a detachable lens-guide assembly.Type: GrantFiled: October 28, 1996Date of Patent: July 28, 1998Assignee: Welch Allyn, Inc.Inventors: John M. Pidhirny, Richard A. Monroe, Michael J. Pileski, Robert J. Wood

Patent number: 5463214Abstract: A method of improving throughput in a scanner whose scanning action is capable of being stopped and started instantly, comprising the steps of A) storing results of a first scan of a target containing indicia in a first region of a memory and B) upon determining that the first scan is complete 1) decoding results of the first scan 2) initiating a second scan, 3) storing results of the second scan of the target containing indicia in a second region of a memory, and 4) awaiting completion of the decoding before initiating an additional scan.Type: GrantFiled: March 4, 1994Date of Patent: October 31, 1995Assignee: Welch Allyn, Inc.Inventors: Andrew Longacre, Jr., Robert M. Hussey, John M. Pidhirny

Patent number: 5286960Abstract: A method and apparatus are provided for detecting bar-space and space-bar transitions in a bar code symbol. A sequence of sparsely sampled analog signals from a photodetector in a bar code scanner is representative of the reflectance pattern of a symbol.Following initialization, a threshold, representing the value of the analog signal at a transition point, is derived from observed samples of the bars and spaces in the bar code symbol. Sampled reflectance information is accumulated as the symbol is scanned, and a program driven microprocessor calculates and repeatedly updates this threshold, using observed maxima and minima in the analog samples, and also referencing a binary output to determine whether a bar or space is currently being viewed.When the values of two successive analog samples bracket this threshold, then a bar-space or space-bar transition has occurred. Linear interpolation is performed on the two samples to determine the transition point and an offset from the first of the two samples.Type: GrantFiled: November 4, 1991Date of Patent: February 15, 1994Assignee: Welch Allyn, Inc.Inventors: Andrew Longacre, Jr., Charles M. Hammond, Jr., William H. Havens, John M. Pidhirny

Patent number: 5065001Abstract: A card or badge reader is provided for reading badges or cards on which there are coded indicia such as a bar code symbol. The reader has a front wall plate that is removably affixed onto the front of the main housing, but separated a slight amount to define a badge reader slot. A wear plate is disposed horizontally between the front wall plate and the front wall of the main housing to define a floor for the badge reader slot. The wear plate comprises an elongated web with downturned end flanges, and is suspended in one of a plurality of parallel horizontal grooves in the front wall plate. The position of the wear plate can be changed from one of these grooves to another, as desired.Type: GrantFiled: July 26, 1989Date of Patent: November 12, 1991Assignee: Welch Allyn, Inc.Inventors: Robert J. Hennick, John M. Pidhirny
