  • Patent number: 7624924
    Abstract: An ergonomic single-line compact laser bar code scanning system having a compact housing for hand-held disposition at a counter. The scanning system is automatically-activated and includes a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch formed integrally in the housing. 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 detected, scanned, and decoded.

  • Patent number: 7431215
    Abstract: An automatically-activated bar code reading system including: a visible laser light source, scanning element and a plurality of stationary mirrors. When arranged in a first configuration, the visible laser light source, scanning element and plurality of stationary mirrors cooperate to produce a visible omni-directional laser scanning pattern with multiple laser scanning lines having substantially uniform spatial and temporal intensity characteristics at a given scanning plane parallel to a scanning window within a working distance of the system.

  • Publication number: 20070138276
    Abstract: A scanner flipper oscillation frequency analyzing method, computer-readable medium, and apparatus is provided. In one embodiment, the method turns a laser off if the laser is on and receives a signal indicative of a flipper oscillation frequency. The method then compares the signal with stored parameters. Based on the comparison, the method adjusts the flipper oscillation frequency when a percentage variation between the signal and the parameters is above a predetermined value. If the flipper oscillation frequency is adjusted a Digital-to-Analog Conversion value associated with the adjustment is stored in memory. The signal received can be transition signals. In other embodiments, an apparatus and computer-readable medium is also provided which performs the similar features recited by the above method.

  • Publication number: 20070119947
    Abstract: A scanner flipper integrity checking method, computer-readable medium, and apparatus is provided. In one embodiment, the method powers a motor for a predetermined amount of time. After the predetermined time has expired a wave is received indicative of the frequency of the oscillation of the flipper. Thereafter, the method uses the wave signal to determine whether there are two consecutive transitions indicative of movement by said flipper. In another embodiment, an apparatus is also provided which performs the similar features recited by the above method.

  • Publication number: 20070114287
    Abstract: A multi-mode laser-based bar code symbol reading device having a hand-supportable housing with a light transmission aperture, wherethrough visible light can exit and enter the hand-supportable housing. A laser scanning engine, disposed within the hand-supportable housing, is controlled to selectively operate in either an omni-directional reading mode or a uni-directional bar code reading mode. In the omni-directional bar code reading mode, the laser scanning engine projects pattern through the light transmission aperture, an omni-directional laser scanning pattern producing multiple laser scanning lines with substantially uniform spatial and temporal intensity characteristics at any given scanning plane parallel to the light transmission aperture within the working distance of the system, and detects and decodes bar code symbols on objects passing through the omni-directional scanning pattern, and produces symbol character data representative of decoded bar code symbols.

  • Publication number: 20050082371
    Abstract: An automatically-activated wireless code symbol reading system comprising a hand-supportable housing having a manually-activatable data transmission switch under automatic communication range dependent control. When a bar code symbol is read, the bar code reader is located inside the predetermined RF data communication range of the system, then the symbol character data string, produced at substantially the same time as the manual activation of the data transmission switch, is transmitted to the base station over the wireless RF communication link. If the device is outside the range, then an audible and/or visual indication is automatically generated, and the packaged symbol character data string is packaged and transmitted to a data storage buffer aboard the bar code reader. Then when the bar code symbol reader is moved within the communication range of the system, the buffered/packaged symbol character data is automatically transmitted to the base station by the RF-based data communication link.

  • Patent number: 6565005
    Abstract: A novel system and method for programming one or more functional parameters of programmable bar code symbol readers and scanners, while avoiding the need to connect a data communication port of a computer system to a bar code symbol reader that is to be programmed. In a first illustrative embodiment, the function-encoded parameters of a master bar code symbol reader are determined using a computer-based-function-parameter device and subsequently buffered in memory buffer contained therein; the buffered function-encoded parameters are used to produce a list of function-encoded bar code symbols which are printed in a specified reading sequence; and the list of printed-function encoded bar code symbols are read in the specified reading sequence so as to configure the bar code symbol reader with the same set of function-encoded parameters that were programmed in the master bar code symbol reader.
