Title: Varl Gurevich and a Patent for Laser-Based Barcode Scanning.

Introduction

Varl Gurevich is an inventor associated with Bohemia, New York, and Symbol Technologies, LLC. His patent work includes a barcode-scanning device that uses a vertical-cavity surface-emitting laser (VCSEL).

Latest Patents

Gurevich is credited with 1 patent: “Bar Code Readers Using Surface Emitting Laser Diode.” The invention describes a scanning device that directs visible or invisible light toward a target, such as a barcode, and detects the reflected light to generate data for decoding and further processing.

The design allows a VCSEL to be mounted directly on a silicon substrate that can move to create a scan pattern. Alternatively, multiple lasers can be mounted on the substrate and activated in sequence to produce a scanning effect without moving the substrate. A collimating lens may also be mounted directly on the laser’s emitting surface. The patent highlights the VCSEL’s low-current operation and its ability to emit substantial light while generating relatively little heat.

Career Highlights

Gurevich’s listed company affiliation is Symbol Technologies, LLC. The barcode-reader patent reflects work on compact laser-based scanning systems and alternative ways to generate scan patterns.

Collaborations

The provided information lists Daniel R. McGlynn and Joseph M. Katz as Gurevich’s coworkers. Their specific roles in the patent or related work are not specified.

Conclusion

Varl Gurevich’s patent describes a barcode-scanning approach that combines VCSEL technology with flexible options for producing a scan, emphasizing efficient light output and reduced heat generation.
