  • Automatically-activated wireless hand-supportable laser scanning bar code symbol reading system with data transmission activation switch and automatic communication range dependent control
    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.

  • Automatically-activated hand-supportable 2-D bar code symbol reading system employing a linear laser scanning pattern generator, an automatic bar code symbol data detector, audible data capture feedback generator, and a manually-activated data transmission activation switch
    Publication number: 20040251307
    Abstract: Disclosed is an automatically-activated wireless 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.

  • Wireless bar code symbol reading system capable of automatically collecting and storing symbol character data when hand-supportable unit is operated outside of its RF data communication range, and automatically transmitting stored symbol character data when the hand-supportable unit is operated within its RF data communication range
