Remote transmitting fenceline monitoring apparatus
First Claim
Patent Images
1. A system for monitoring air samples for potentially unacceptable levels of contaminants and communicating to a remote location when contaminates are detected, the system comprising:
- a contaminant detection device adapted to collect air samples at a remediation site and to analyze said air samples directly, while at said site, to determine if contaminants exist in the air samples;
an audio signal generator connected to said detection device for producing an audio signal instantaneously when the detection device indicates that unacceptable contamination levels exist in the air samples;
an automatic audio transmitter for transmitting said audio signal to a remote location;
a remote audio receiver for receiving said audio signal from said transmitter, independent of any direct physical connection between said audio receiver and said transmitter, and alerting an individual who hears said audio signal at said audio receiver that the contamination signal has occurred at the detection device; and
a portable weatherproof enclosure including an exterior warning means visible from a distance suitable for stand alone usage in an outdoors environment independent of the need for human operator intervention, within which said audio signal generator, said audio transmitter and said contamination detection device are contained.

Abstract
An apparatus placed at the "fenceline" (perimeter) of a site, to detect the possible existence of contaminants within the air and transmit an audio signal to a remote location indicating an irregularity in the air quality. Conventional audio transmitters such as a walkie-talkie may be used to detect an audio alarm signal from the contamination detection device and be received by a receiver, such as another walkie-talkie at a remote location. The monitoring system may be housed in a portable enclosure to protect the equipment from weather, vandalism or theft.
