Abstract

The present invention provides a method of monitoring the position of a vehicle, vessel, rail car, barge, tanker truck that is loaded with bulk or hazardous material. A G.P.S unit is set to send a signal to a radio transmitter if the unit moves beyond a maximum permissible distance (for example, 50 feet or more). An oxygen sensor can be used to send a signal to a radio transmitter if oxygen levels fall below a selected minimum concentration. The radio transmitter can send the message to a tugboat crew, police department, fire department, company headquarters, civil defense office or other personnel if either of the unit has moved beyond the selected maximum travel distance or if oxygen levels fall below a minimum concentration. In addition to the radio transmission of oxygen concentration data and/or G.P.S position data, visible or audible alarms can be used such as strobe light, horn or the like. Also disclosed is a system for concealment of chemical and/or biological sensors in a building for urban or industrial environments.

Claims

1. A system for concealing sensors in an urban environment, comprising:

(a) a sensor, the sensor sensing chemical or biological agents;

(b) a container, the container housing the sensor and resembling an electrical box;

(c) a pipe connected to the container, the pipe resembling electrical conduit;

(d) a vent connected to the pipe, the vent resembling a dryer vent;

(e) a fan operatively connected to the container, the fan causing an airflow to be drawn through the container and pipe, and air flow to exit through the vent.

2. The system of claim 1, further comprising a control panel, the control panel being operatively connected to the sensor and fan.

3. The system of claim 2, wherein the system is installed in a building with the first and second vents being located on the exterior of the building and the panel being located on the interior of the building.

4. The system of claim 2, wherein the sensor sends a warning signal if chemical or biological agents are detected.

5. The system of claim 2, wherein the system is installed in a building and the container is located on the exterior of the building and the panel located on the interior of the building.

6. A system for concealing sensors in an urban environment, comprising:

(a) a sensor, the sensor sensing chemical or biological agents;

(b) a first vent, the first vent resembling a dryer vent;

(c) a second vent, the second vent resembling a dryer vent;

(d) a pipe connected to the first and second vents and housing the sensor;

(e) a fan operatively connected to the pipe, the fan causing an airflow to be drawn through the first vent, pipe, and air flow to exit through the second vent.

7. The system of claim 6, further comprising a control panel, the control panel being operatively connected to the sensor and fan.

8. The system of claim 6, wherein the sensor sends a warning signal if chemical or biological agents are detected.
