Abstract: A hazard beacon has an interface to a vehicle wiring harness configured to detect that vehicle emergency indicators have been deployed, a plurality of separately strobe capable light segments forming a hazard symbol, and a microcontroller controlling operation of the plurality of separately strobe capable light segments.

Abstract: A chlorine generating apparatus is disclosed herein by which chlorine gas or sodium hyperchlorite is generated in small quantities from a brine solution economically enough to be practical for use in the backyard swimming pool. The apparatus includes a free standing unit and cell utilizing only salt as its raw material to generate the chlorine required. The chlorine generating cell incorporates a chemical pump for forcibly urging the resulting product to the pool without the use of mechanical pumps or membranes. A device is included whereby hardness minerals are prevented from being deposited within the cell. New methods of reducing maintenance and increasing reliability are also disclosed.

Abstract: A chlorine generating apparatus is disclosed herein by which chlorine gas and/or sodium hypochlorite is generated in small quantities from a brine solution economically enough to be practical for use in the backyard swimming pool. The apparatus includes a freestanding unit utilizing only salt, water and electricity as its raw materials to generate the chlorine required. A chlorine-generating electronic cell incorporates a pumping action for forcibly urging the resulting product through a mixing unit to a storage tank without the use of mechanical pumps. A process is included whereby hardness minerals are precipitated from incoming raw water preventing mineral buildup on the cathode portion of the electronic cell.
