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

Optical lens element with a prescription zone, suitable for use in wraparound or protective type eyewear. The element may also include a peripheral vision zone, with no prismatic jump between the zones. Design methods for the prescription zone include temporally rotating a prescription section about a vertical axis through the optical center thereof, and/or decentring the optical axis of said prescription section relative to the geometric axis thereof, and providing partial surface correction for astigmatic and/or mean power errors. For prescription powers in the range &#x2212;6.0 to +6.0 diopters with 0 to 3 cyl, the optical lens element may be designed such that its front surface can be mounted in a frame of constant curvature of at least 5.0 diopters, with its back surface providing good clearance from temples and eyelashes. Applications include ophthalmic sunglass lenses.

The element may also include a peripheral vision zone, with no prismatic jump between the zones. Design methods for the prescription zone include temporally rotating a prescription section about a vertical axis through the optical center thereof, and/or decentring the optical axis of said prescription section relative to the geometric axis thereof, and providing partial surface correction for astigmatic and/or mean power errors. For prescription powers in the range &minus;6.0 to &plus;6.0 diopters with 0 to 3 cyl, the optical lens element may be designed such that its front surface can be mounted in a frame of constant curvature of at least 5.0 diopters, with its back surface providing good clearance from temples and eyelashes. Applications include ophthalmic sunglass lenses.

A battery pack is detachably secured by a snap-type action to a handle of a generally gun-shaped scanning head in a system for electro-optically reading coded indicia, such as bar code symbols. The battery pack includes a set of rechargeable batteries mounted in a casing.

An auditory beeper mounted in a hand-held scanning head of an electro-optical system for reading light-reflective indicia signals a user that the indicium has been found and is ready to be read by generating a series of sounds or beeps whose rate of beeping changes upon finding the indicium.

Enhanced ophthalmic lens

A region of light-reflective indicia is visibly illuminated in order to locate the indicia relative to a hand-held of a system for electro-optically reading the indicia. The region is formed by aiming optics and a light source for generating a visible aiming beam. The region can be single spot, a pair of spots, or a line.

Hand-held scanning head with aiming beam

A target bearing a coded indicium is found by a system for electro-optically reading indicia. Upon the determination that the indicium is located within a range of working distances relative to a hand-held housing, a user is prompted that the indicium is ready to be read. A sonic signal is transmitted by a ranger, and a return echo from the indicium is received. An auditory prompt, such as a single tone or a series of tones, advises the user that the indicium is within range.

A portable laser diode scanning head, aimable at each symbol to be read, emits and receives non-readily-visible laser light, and is equipped with a trigger-actuated aiming light arrangement for visually locating and tracking each symbol. A compact laser diode optical train and an optical folded path assembly, as well as an interchangeable component design and an integral window construction for the head also are disclosed.
