Patent number: 6536696Abstract: A point of sale printer includes a paper supply mechanism rotatably mounting a paper supply roll within a frame through a resiliently mounted bearing member extending into each end of a central hole in the roll. The frame is manually pivoted between an open position, in which the roll is installed and removed by moving the bearing members outward with movement of the roll, and a closed position, in which the roll is rotatably held in place, with outward movement of the bearing members being prevented by stops within the printer. With the frame in its closed position, a paper web is pulled from the roll for printing. An alternate configuration allows the printer to use a narrow paper roll.Type: GrantFiled: March 1, 2001Date of Patent: March 25, 2003Assignee: International Business Machines CorporationInventors: Melissa Ann Fiutak, Richard Hunter Harris, Robert Andrew Myers, Kevin Hunter Vorhees

Publication number: 20030043169Abstract: A method and system for performing multi-sample, antialiased rendering of images by performing multi-sample antialiasing at the primitive level. Geometric primitives used to represent a graphics environment are set-up, and then shifted by a sub-pixel offset and rendered to generate values for pixels of an intermediate image. The shifting and rendering is repeated for the geometric primitive, each time generating values for pixels of another intermediate image. The values for the pixels of the intermediate images are combined to produce values for the respective pixels of the resulting image.Type: ApplicationFiled: August 31, 2001Publication date: March 6, 2003Inventor: Kevin Hunter

Patent number: 6408727Abstract: A printer mechanism includes a single motor turning a system drive gear in a paper feeding direction, and in a cam driving direction, opposite the paper feeding direction. When the system drive gear is turned in the paper feeding direction, a paper feeding spring clutch drives a paper feed roll with the system drive gear. When the system drive gear is turned in the cam driving direction, a drive cam is driven by a cam driving spring clutch. The drive cam has a first surface driving a moving knife blade across a stationary knife blade in a cutting direction, and in a return direction opposite the cutting direction. With this movement in the cutting direction, the moving knife is held against the stationary knife blade, and, with movement in the return direction, the moving knife is moved away from the stationary knife blade, by means of a second surface of the drive cam.Type: GrantFiled: January 12, 2000Date of Patent: June 25, 2002Assignee: International Business Machines CorporationInventors: Richard Hunter Harris, Jeff David Thomas, Kevin Hunter Vorhees

Patent number: 6108656Abstract: The present invention is a system and method for providing automated access to electronic information stored in a database in either a local or remote location. The system utilizes a machine-readable code printed on a document, referred to herein as an intelligent document since it stores information used to automatically access the information. The machine-readable symbol comprises encoded source data, wherein the source data comprises application launch information as well as file location information. The source data is encoded and printed, and then distributed by the vendor by any logical means to the end user. The end user then scans the code via appropriate code scanning (e.g. bar code scanning) equipment, decodes the raw decoded data, and the file location information is then used to access the appropriate file. In a preferred embodiment, a Web browser program is launched, and the URL of the vendor's Web site is accessed through the Internet.Type: GrantFiled: May 11, 1999Date of Patent: August 22, 2000Assignee: NeoMedia Technologies, Inc.Inventors: Robert T.

Patent number: 6047892Abstract: A electro-optical memory includes a substrate on which is printed (or otherwise inscribed) a complex symbol or "label" or "bar code" of a high density two-dimensional symbology. The bar code contains component symbols or "codewords" which are placed in row and column formation, with a variable number of codewords per row, and a variable number of rows. The symbology utilizes implicit bar code encoding scheme for implicit encoding the number of rows and the number of columns of codewords, as well as a predetermined amount of error correction. The symbology is capable of supporting a fixed number of bar code variants, with each variant having a predetermined number of rows and columns of codewords, and a predetermined error correction capability. For some codewords the implicit encoding scheme is combined with a gray coding scheme to reduce the inter-row codeword crosstalk.Type: GrantFiled: July 14, 1998Date of Patent: April 11, 2000Assignee: Symbol Technologies, Inc.Inventors: Frederick Schuessler, Kevin Hunter, Sundeep Kumar, Cary Chu

Patent number: 5971640Abstract: A gear drive system for a printer designed to print upon a continuous roll of paper and having a blade used to cut off printed portions of paper from the paper roll is implemented. The gear drive system has a drive gear which slips against a toothless portion of a driven gear while paper is being fed through the printer for printing by a print head. When printing stops, the drive gear reverses its rotation, causing the driven gear to engage the drive gear. A cutter blade is controlled by the driven gear, with the blade cutting off the paper as the drive gear is in reverse rotation. After the paper is cut, the drive gear resumes its forward rotation, rotating the blade away from the paper. After the blade has been rotated, the drive gear continues to turn, but slips on the toothless portion of the driven gear. Friction losses are minimized as the energy lost as friction is low and full torque is applied to both cutting and opening rotations of the cutter blade.Type: GrantFiled: October 13, 1998Date of Patent: October 26, 1999Assignee: International Business Machines CorporationInventors: James Gabriel Brewington, Richard Hunter Harris, Jeff David Thomas, Kevin Hunter Vorhees

Patent number: 5933829Abstract: The present invention is a secure system and method for providing automated access to electronic information stored in a database in either a local or remote location. The system utilizes a machine-readable code printed on a document, referred to herein as an intelligent document since it stores information used to automatically access the information. The machine-readable symbol is encoded with source data (including a file location pointer) that is first obfuscated by generating a checksum of the source data, encrypting the source data by using the checksum as an encryption key, and assembling the checksum with the encrypted source data prior to encoding. The machine-readable symbol is then printed and distributed by the vendor by any logical means to the end user. The end user then scans the code via appropriate code scanning (e.g.Type: GrantFiled: November 8, 1997Date of Patent: August 3, 1999Assignee: NeoMedia Technologies, Inc.Inventors: Robert T.

Patent number: 5813781Abstract: A document feed roller opening mechanism and a method for operating that opener provide efficient and reliable operation. In the document feed roller opening mechanism, a print head transport motor is used to open the document feed rollers. A carrier post is implemented to engage a document insert lever when the print head carrier is positioned over a cam on the document insert lever. Thus engaged, the document insert lever rotates to pull a left end of the document insert pressure roller. The left end of the document insert pressure roller slides towards a front of the printer and a right end pivots slightly in a right frame. A spring implemented therein compresses as the document insert pressure roller moves away from a stationary document insert feed roller. This spring provides pressure to the document insert feed roller when the rollers are together. With the document insert feed rollers open, one may easily slide a document in from the side of the printer.Type: GrantFiled: January 10, 1997Date of Patent: September 29, 1998Assignee: International Business Machines CorporationInventors: Richard Hunter Harris, Jeff David Thomas, Kevin Hunter Vorhees
