APPARATUS FOR AND METHOD OF MITIGATING INTERFERENCE BETWEEN PULSED AMBIENT LIGHT AND DATA CAPTURE DEVICES
First Claim
1. An apparatus for enhancing performance of a data capture device operative for electro-optically reading a target in a venue for transmitting an information signal by pulsing ambient light that interferes with operation of the data capture device, the apparatus comprising:
- a converter for converting the information signal to an analog information signal; and
a switching power supply operatively connected to the converter and to a lighting fixture that emits the ambient light, the switching power supply being operative for receiving the analog information signal from the converter, for generating an output analog control signal from the received analog information signal, and for controlling the light fixture with the output analog control signal to emit the ambient light in a time-varying, non-pulsed, analog manner to mitigate interference with the operation of the data capture device.

Abstract
Performance of a laser-based moving beam reader for electro-optically reading a target is enhanced in a venue for transmitting an information signal by pulsing ambient light that interferes with operation of the reader. A converter converts the information signal to an analog information signal. A switching power supply is operatively connected to the converter and to a lighting fixture that emits the ambient light. The switching power supply receives the analog information signal from the converter, generates an output analog control signal from the received analog information signal, and controls the light fixture with the output analog control signal to emit the ambient light in a time-varying, non-pulsed, analog manner to mitigate interference with the operation of the reader.
