  • Automatic hand-supportable omnidirectional laser projection scanner with handle-controllable projection axis
    Patent number: 5796091
    Abstract: A fully automatic bar code symbol reading system having an automatic (i.e., triggerless) portable bar code symbol reading device with an omnidirectional projection laser scanning engine mounted within the head portion of its hand-supportable housing, and an associated base unit positioned within the data transmission range without a physical wiring connection. The hand-supportable bar code symbol reading device produces a narrowly confined scanning volume for omnidirectional scanning of the code symbols presented, while preventing unintentional scanning of code symbols on nearby objects located outside the scaning volume.
    Type: Grant
    Filed: May 13, 1996
    Date of Patent: August 18, 1998
    Assignee: Metrologic Instruments, Inc.

  • Mass-balanced automatic hand-supportable laser projection scanner for fatigue-free omnidirectional scanning of bar code symbols
    Patent number: 5767501
    Abstract: A fully automatic bar code symbol reading system which has an automatic (i.e., triggerless) portable bar code symbol reading device with an omnidirectional projection laser scanning engine mounted within the head portion of its hand-supportable housing, and an associated base unit positioned within the data transmission range of the portable unit without a physical wiring connection to the portable unit. The hand-supportable bar code symbol reading device produces a narrowly confined scanning volume for omnidirectional scanning of code symbols presented within the scanning volume, while preventing unintentional scanning of code symbols on nearby objects located outside of the scanning volume.
