APPARATUS AND METHOD TO FACILITATE WIRELESS COMMUNICATIONS OF AUTOMATIC DATA COLLECTION DEVICES IN POTENTIALLY HAZARDOUS ENVIRONMENTS

摘要

A system useful in providing communications with automatic data collection (ADC) devices employs an antenna located in a potentially hazardous environment, a radio circuit located in a non-hazardous environment, and a coupling apparatus to provide an interface between the antenna and the radio circuit that prevents electrical discharges from occurring in the potentially hazardous environment.
