Abstract:
A method of and system for setting and switching user preferences between system operators, to provide a higher return on investment (ROI) and a more satisfying work environment. The system allows operators to easily select and implement particular customizable system configuration parameters (SCPs) in a code symbol reading system, based on personal preferences of the system operator, which can lead to more effective scanning performance. A different set of customizable SCPs are programmably stored in system memory (e.g. EPROM) for each system operator/user registered to use the system, to improve the quality of the working environment and increase worker productivity.
Abstract:
An indicia reading terminal is describe that has a configurable mode, initiated by a trigger control, and in which can be implemented change to various operating characteristics of the terminal. In one embodiment, the trigger control comprises a trigger that is manually actuated by an end user to initiate and/or capture data and information encoded in a decodable indicia. The trigger is also utilized to permit the end user to select from among one or more operating characteristics, such as in one example wherein the trigger is used to scroll or toggle through the operating characteristics.

Abstract:
Method and apparatus for automatically reading bar code symbols is disclosed. One aspect of the present invention concerns a method of reading bar code symbols using an automatic hand-holdable bar code symbol reading device. In general, the automatic bar code symbol reading device comprises a hand-holdable housing containing operative elements which provide an object detection field and a scan field each defined external to the housing. The method involves automatically detecting the presence of an object within the object detection field by sensing energy reflected off the object. In a preferred embodiment, the energy reflected off the object is IR radiation produced from an object sensing energy source disposed within the housing. In automatic response to the detection of the object within the object detection field, the hand-holdable device detects the presence of a bar code aligned by the user within the scan field using a laser beam produced within the housing. Then, in automatic response to the detection of a bar code in the scan field, the automatic hand-holdable bar code symbol reading device reads the detected bar code in the scan field by producing scan data signals from the detected bar code and thereafter collecting and analyzing the same. Another aspect of the present invention concerns a hand-holdable data collection device adapted for use with the automatic bar code symbol reading device to form a portable symbol reading system which is versatile and simple to use.
Abstract:
Holographic laser scanner (1) of ultra-compact design which produces a three-dimensional laser scanning volume that is capable of reading one-dimensional and two-dimensional bar code symbols and other types of graphical indicia within large or small scanning volumes of highly confined (i.e., controlled) geometry, using holographic optical elements (13A, 13B, 13C) including a rotating disc (7) that supports a plurality of facets (9), and at least one visible laser diode(s) (12A, 12B, 12C). The three-dimensional laser scanning volume has multiple focal planes and a highly confined geometry extending about a projection axis extending from the scanning window, including an aperture, of the holographic scanner (1).
Abstract:
A miniature device for moving a reference plane or point on an axis in rotational or x-y directions, particularly useful for two dimensional beam scanning. The device consists of a ferromagnetic ring surrounding a magnetic core which is flexibly mounted and suspended within it. Electric current at various frequencies is supplied to coils wrapped about and mounted within the ring. The core provides a magnetic field within the ring which defines its coordinates with respect to the ring and its coils and interacts with current applied to the coils to produce torque. The flexible mount suspending the core within the coils permits relative movement therebetween in response to the varying current. Motion of the core may be used to position optical elements. In one embodiment, a mirror is attached to the core and a laser beam reflected off the mirror produces a variety of two dimensional scan patterns. The shape of the patterns is determined by selection of the frequencies of current applied to the coils.
