Patent number: 6076734Abstract: The present invention teaches a variety of methods and systems for providing computer/human interfaces. According to one method, the user interfaces with an electronic device such as a computer system by engaging a sensor with desired regions of an encoded physical medium. The encoded physical medium is preferably chosen to provide intuitive meaning to the user, and is thus an improved metaphor for interfacing with the computer system. Suitable examples of the encoded physical medium include a data-linked book, magazine, globe, or article of clothing. Some or all of the selected regions have had certain information encoded therein, information suitable for interfacing and controlling the computer system. When the user engages the sensor with a region having certain encoded information, the certain encoded information is interpreted and an appropriate action taken. For example, the sensor or the computer system may provide suitable feedback to the user.Type: GrantFiled: October 10, 1997Date of Patent: June 20, 2000Assignee: Interval Research CorporationInventors: Thomas J.

Patent number: 6039252Abstract: A bar code reading system capable of reconstructing irregularly damaged bar codes includes an input device such as an omnidirectional or CCD scanner, processors for determining whether the bar code symbol has been damaged, and a decoder. The scanner initially scans the bar code to determine the symbology that governs the bar code. Once the symbology has been obtained, an expected length for each symbol can be calculated. The scanner then individually scans each symbol and compares the symbol's length to its expected length. If the lengths differ by a significant amount, the symbol is assumed to be damaged and information about the elements of each symbol are stored in memory. The scanner then scans in a reverse direction and stores information about the symbol in memory. A processor then determines all of the possible permutations of element widths from the stored information. Each permutation is checked against all possible decoded symbols until a single, decodable symbol is found.Type: GrantFiled: December 14, 1995Date of Patent: March 21, 2000Assignee: Intermec CorporationInventor: Pavel A. Maltsev

Patent number: 6015091Abstract: A code symbol reading device includes a portable housing that contains a light source. Light from the light source is projected into a scan field external to the housing and onto a code symbol on an object located within the scan field. The light reflected off the code symbol is detected within the housing to produce scan data that is indicative of the detected light intensity. The scan data is processed to detect and decode the code symbol and to produce symbol character data that are representative of the decoded code symbol. A data packet utilizing the symbol character data is synthesized and modulated onto a carrier signal that is transmitted to a base unit where the carrier signal is demodulated and the data packet recovered. The received data packet is analyzed to recover the symbol character data, and an acknowledgment signal is produced to acknowledge the receipt of the symbol character data at the base unit.Type: GrantFiled: July 9, 1997Date of Patent: January 18, 2000Assignee: Metrologic Instruments, Inc.Inventors: George B. Rockstein, David M. Wilz, Stephen J. Colavito, Gene German, Carl Harry Knowles
