Abstract: The NiteNob is a totally new take on an item taken for granted in every home or dwelling; the door knob. What makes the NiteNob stand out versus a standard door knob is the feature of a built in safety feature, the LED ring which allows the internal room side of the door knob to shine a dim light. The LED light which is emitted from the NiteNob can easily be located in a dark or smoke filled room allowing a person to quickly make their way toward the exit. In a non emergency situation the NiteNob assumes the docile role of reassuring night light which many people find soothing and comforting in an otherwise dark bedroom, hallway or bathroom.

Abstract: The automotive coolant filter was devised as a result of the inventor servicing an automotive cooling system and witnessing the evidence of contaminants depositing on cooling system surfaces. The inventor reasoned that other vital engine fluids such as motor oil and transmission fluid are filtered, wouldn't the coolant benefit also from filtration? Of course! By the simple filtration of circulating engine coolant through a paper or a fiber corrugated element, the majority of transient contaminants will be trapped. This in turn will extend the life of anti-freeze coolant as well as vital engine cooling system components.
