Contaminating spill detection arrangement

A contamination spill detection arrangement of the type adapted to detect the presence of predetermined contaminants in a body of water and transmit signals to a remotely located receiving station in response to the detected presence of the contaminants, and comprising, in combination:

• a plurality of detector station means positioned in the body of water in a predetermined spaced array, and each of said detector station means comprising:
• a plurality of contamination detector elements, each of said plurality of contamination detector elements at least partially submerged in the water, and each of said plurality of contamination detector elements having a predetermined characteristic responsive to the presence of the predetermined contaminant thereon for varying said predetermined characteristic for the condition of the contaminant impinging on said contaminant detector element;
• sensing means coupled to said plurality of contaminant detector elements for sensing said variation in said predetermined characteristic in each of said contamination detector elements, and said sensing means further comprising first information signal generating means for generating a plurality of first information signals different from each other and each of said plurality of first information signals corresponding to one of said plurality of contamination detector elements;
• transmission means for receiving said plurality of first information signals and generating a plurality of transmission signals in response thereto, each of said transmission signals different from each other and each of said transmission signals corresponding to one of said plurality of first information signals, and transmitting said plurality of transmission signals to locations remote said detector station means.

A contamination spill detection arrangement of the type adapted to detect the presence of predetermined contaminants and transmit signals to a receiving station in response to the detected presence of the contaminants, and comprising, in combination:

• at least one detector station means positioned at a predetermined location and said at least one detector station comprising:
• detector element means comprising at least one contaminant detector element, said at least one contaminant detector element having a predetermined characteristic responsive to presence of the predetermined contaminant thereon and varying said predetermined characteristic for the condition of the contaminant impinging on said at least one contaminant detector element:
• sensing means coupled to said at least one contaminant detector element for sensing said variation in said predetermined characteristic, and said sensing means further comprising information signal generating means for generating a first information signal in response to said variations;
• transmitter means for receiving said first information signal and transmitting said first information signal to regions remote said detector station means;
• status signal generating means for generating a second information signal different from said first information signal coupled to said transmitter means;
• cyclically operable means operatively connected to said status signal generating means for cyclically operating said status signal generating means whereby said second information signal is cyclically transmitted by said transmitter means;
• receiving station means spaced from said predetermined location for receiving said first and said second information signals and generating a first output signal in response to said first information signal and a second output signal different from said first output signal in response to said second information signal.
