Abstract: Internal combustion engines operate by igniting a mixture of liquid fuel and air inside its combustion chamber. The energy from the ignition is converted to mechanical energy that is used to power a vehicle. Research indicates that adding hydrogen gas into the combustion chamber improves the efficiency of the engine. The present invention is an electrolysis system that produces hydrogen and oxygen gases and injects them into the fuel line of the engine to create a mixture of the gases and the liquid fuel that is subsequently introduced into the combustion chamber for ignition. The operating temperature of the engine is lower if the gases are injected into the fuel line rather than directly into the combustion chamber.

Abstract: A video surveillance camera is provided that includes a first camera objective directed towards a primary surveillance field of view and at least a second camera objective that is concealed within the camera and directed towards a second covert field of view. The second camera objective is mounted within the camera body in a manner that makes it undetectable, while allowing the camera objective to freely observe the covert field of view. In a first embodiment, the video camera includes a first camera objective affixed to the front of the camera housing and at least a second camera objective mounted in a fixed, concealed position within the housing. Alternately, the at least one second camera objective may be mounted within the housing in an adjustable fashion to allow the second camera objective to be aimed independently of the camera housing orientation itself.
