Abstract: An apparatus is provided for collecting medical waste fluids. The apparatus includes: a medical waste collection container for collecting medical waste fluids; first and second electrically conductive sensing elements disposed inside the container so as to be exposed to fluid collected in the container, where the first and second sensing elements are located inside the container at a position corresponding to a full fluid level at which point the container is full of fluid; and an electronic circuit coupled to the sensing elements for generating a full alarm signal when the electronic circuit determines that current can flow between the first and second sensing elements as a result of fluid in the container reaching the full fluid level and thereby completing a current path between the first and second sensing elements.

Abstract: A mileage tracking system including an input device mounted in the vehicle for receiving one of a first and second door unlock signals, and a tripmeter. The tripmeter is coupled to the input device and to a vehicle odometer sensor for accumulating a first accumulated travel distance during vehicle travel following receipt by the input device of the first door unlock signal, and for accumulating a second accumulated travel distance during vehicle travel following receipt by the input device of the second door unlock signal. The tripmeter does not accumulate the first accumulated travel distance during vehicle travel following receipt by the input device of the second door unlock signal. The mileage tracking system also preferably includes a display coupled to the tripmeter for selectively displaying the first and second accumulated travel distance. The input device is preferably a receiver for receiving a signal from a remote transmitter.
