An integrated optical communication and barcode scanning module suitable for use with portable electronic devices is provided. In a first mode of operation the module functions as an Infrared Data Association (IrDA) compatible communications interface. In a second mode of operation, IrDA communications is disabled, and the module functions as a barcode scanner. The module may be switched back and forth between the two modes of operation or operated simultaneously.

Integrated bar code scanner and communications module

An optical scanning module and a scanner incorporating the scanning module for reading bar codes and other optical indicia that consists of a printed circuit board, an elongated elliptical aperture in the scanning module that is spaced from the circuit board, a light source mounted on the printed circuit board for projecting at least one beam of light through the aperture and onto a dataform to be read, and a detector mounted on the printed circuit board for sensing light reflected from the dataform and through the aperture. Light baffle is preferably used to isolate light source from the detector in the optical scanning module of the present invention.

Low cost bar code reader

A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.

Down-loadable hand-held optical reader

An electrical interface for a scan engine includes a plurality of control pins including a range limiter mode pin, laser enable and scan enable pins, a signal output pin and a start-of scan indicator pin. Operation of the scan engine can thus be controlled to reduce power consumption and laser on-time as desired.

Interface and method for controlling an optical reader having a scanning

In bar code symbol scanning systems employing laser, optical and sensor components a superstructure mounted on a housing and having a movable exit port to adapt the housing to steer a laser beam through the exit port to a particular course. Both right and left handed users are thereby accommodated.

Hand held bar code scanner with adjustment of direction of emitted light

A hand-mounted scanning system for reading indicia having parts of different light reflectivity, including a housing having a window and an actuatable electro-optical scanner in the housing for projecting a light beam through the window to indicia to be read, for scanning the indicia. The system further detects light of variable intensity that is reflected off the indicia to generate an electrical signal representative of the indicia. The housing is mounted on a glove worn on an operator's hand and the scanner initiates reading of the indicia upon movement of the operator's hand, or automatically by object recognition.

Hand-mounted scanner with automatic manual initiation of reading indicia

A hands-free scanning system for reading indicia having parts of different light reflectivity, including a housing having a window and an actuatable electro-optical scanner in the housing for projecting a light beam through the window to indicia to be read, for scanning the indicia. The system further detects light of variable intensity that is reflected off the indicia to generate an electrical signal representative of the indicia. The housing is mounted on an arm of an operator and the scanner initiates reading of the indicia upon movement of the operator's hand relative to the arm by means of an actuator switch.
