Patent number: 7252238Abstract: Disclosed is an automatically-activated code symbol reading system comprising a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner.Type: GrantFiled: April 25, 2003Date of Patent: August 7, 2007Assignee: Metrologic Instruments, Inc.Inventors: David M.

Patent number: 7040540Abstract: A code symbol reading device includes a portable housing that contains a source of optical energy. This optical energy is projected into a scan field external to the housing and is incident upon a code symbol situated on an object located within the scan field. Optical energy reflected off the code symbol is detected within the housing to produce scan data that is indicative of the detected optical energy. 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 constructed and then used to modulate an electromagnetic carrier sign that is transmitted to a base unit. At the base unit, the carrier signal is demodulated and the data packet is recovered. The received data packet is processed to recover the symbol character data, and an acknowledgment signal is generated to acknowledge the receipt of the symbol character data at the base unit.Type: GrantFiled: August 12, 2003Date of Patent: May 9, 2006Assignee: Metrologic Instruments, Inc.Inventors: Carl H.

Patent number: 6945463Abstract: A multi-channel scanner having several photodetectors (12a-12d) and several lasers (10a-10d) for scanning along multiple paths (50a-50d) incorporates a separate input channel (26a-26d) for each photodetector. Each channel provides a sequence of data elements representing light reflected from points along the associated scanning path, and the data elements from each channel are stored in separate FIFO buffers (20a-20d). A multiplexer (22) takes data elements from the various buffers so as from a consolidated stream of data elements (80) incoporating the data elements from the various channels. This stream is processed in a single decoder (24) to recover data denoted by the bar code. Use of a single decoder minimizes the cost and size of the system.Type: GrantFiled: April 18, 2001Date of Patent: September 20, 2005Assignee: Metrologic Instruments, Inc.Inventors: George B.

Patent number: 6863217Abstract: By automatically adjusting the object detection mechanism of a bar code scanner from a long range mode of operation to a short range mode of operation, the scanner will remain capable of detecting and decoding bar codes even if the object detection mechanism repeatedly detects the presence of a background object. The techniques of the present invention commence when the bar code scanner is placed in a position such that the scanner's object detection mechanism repeatedly detects a background object such as a counter top or conveyer belt. The object detection mechanism is set to the long range mode of operation if it is not already so set. In the case of a stand-mounted scanner, a test is performed to ascertain whether or not the scanner is in its stand, and the method will only proceed once the scanner is resting in the stand.Type: GrantFiled: August 13, 2003Date of Patent: March 8, 2005Assignee: Metrologic Instruments, Inc.Inventors: Donald T. Hudrick, David M. Wilz, Sr., Garrett K. Russell, George B. Rockstein, Mark S. Schmidt
