A bar code scanning device, system and method that utilizes one or more vertical cavity surface emitting laser diodes for producing at least one laser beam, where the vertical cavity surface emitting laser diodes are disposed on a substrate, and wherein the produced laser beam is substantially an essential single spatial mode laser beam. The bar code scanning device, system and method of present invention also comprise a photodiode attached to the substrate and arranged to receive at least a portion of the beam of light reflected off the scanned bar code or symbol.

Scanning devices and methods using surface emitting laser diodes

A suspension mass is mounted for swinging movement relative to, and extends between, a pair of fixed posts spaced apart from each other on an annular support mounted in a portable electronic device. The mass is connected to the posts through a pair of breakable links.

A hand-held bar code reader including a housing bounding an interior, a window, a generally planar printed circuit board mounted in the interior, and an optical scanning assembly mounted on the board and including a scanner for directing a light beam through the window at an acute angle relative to the board. A scanning element of the reader is manufactured by spacing a first and second support element apart by a gap bounded by edges of the support elements; injection molding a curable, elastomeric material in flowable form over the edges and into the gap; and allowing the curable, elastomeric material to cure and bond to the edges, and form a flexible hinge in the gap for enabling movement of the support elements relative to one another both away from and toward a stable rest initial position.

Light is focused in a system for electro-optically scanning and reading bar code symbols by an aperture stop having a first optical portion for optically modifying a first part of a light beam to have a beam cross-section of a known size within a depth of field in which a symbol to be read is scanned by the first beam part, and a second light-transmissive, optical portion bounding the first portion and operative for optically modifying and directing a second part of the light beam away from the first part.

Laser focusing aperture and method

An electrical coupling arrangement, particular for digital transfer, has a female connector and a male connector. Each connector has an electrical coupling portion via which the data are transferred. The connectors are held together by means of a latching arrangement consisting of a pair of fixed latching posts on the male connector which mate with a corresponding pair of flexible latching sleeves which are molded within the body of the female connector. The self-latching action means that the coupling may be effected rapidly but also securely. The invention extends to a method of manufacture, with the body of the female connector being molded around latching sleeves which may have a lower melting point than the material making up the body itself.

Electrical connector

An interface arrangement is connected between a scanning head for electro-optically reading bar code symbols and a host device having a host processor operative for processing signals with a predetermined data exchange format. The interface arrangement includes a housing; a first connector on the housing for direct connection to the host device; a second connector on the housing for direct connection to a head cable connected to the scanning head; and a conversion circuit within the housing for converting decoded signals generated in the head into data signals having a format compatible with the predetermined data exchange format of the host processor.
