CODE SYMBOL READING SYSTEM HAVING ADJUSTABLE OBJECT DETECTION

摘要

A code symbol reading system is provided. The code symbol reading system has an object detection subsystem that can be configured to detect only those objects that are positioned at a specified distance from the system. The object-detection subsystem thereby initiates the scanning process only when an object is detected at substantially the specified distance from the system.

主权项

1. A system, comprising:
a code-symbol-capturing subsystem for receiving reflected electromagnetic radiation from a field of view; an object-detection subsystem for emitting electromagnetic radiation toward an object within the field of view; and a calibration processor for adjusting a power of the electromagnetic radiation emitted by the object-detection subsystem in response to a power of the reflected electromagnetic radiation received by the code-symbol-capturing subsystem; wherein the code-symbol-capturing subsystem acquires information about code symbols within the field of view if the power of the reflected electromagnetic radiation received by the code-symbol-capturing subsystem is substantially equal to a predetermined target reception power.
