Abstract: A pressure measurement system includes a multiplexer unit which inputs a plurality of electrical signals representative of pressures, and a comparison unit which compares the electrical signals among each other to determine a specified signal characteristic, wherein the multiplexer unit selects one of the electrical signals as an output signal based on the determination of the specified signal characteristic, and outputs the selected signal.

Abstract: A method for determining engine crankshaft position determines the position of a rotating crankshaft using one or many crankshaft position sensors. The sensor output signals representing crankshaft position are digitized and specific timing positions are derived. The sampled timing positions are compared to a known position template to determine crankshaft position.

Abstract: A method of determining an air-fuel ratio of an internal combustion engine in real-time includes: calibrating sensitivity of a universal exhaust gas oxygen sensor to a plurality of gases; inputting to a universal exhaust gas oxygen sensor controller a molecular composition of Hydrogen, Carbon, Oxygen, and Nitrogen which comprise a combustion fuel in use in the internal combustion engine; calculating with the universal exhaust gas oxygen sensor controller an air-to-fuel ratio by performing a chemical balance equation calculation based on the universal exhaust gas oxygen sensor sensitivity calibration and the input combustion fuel molecular composition; and transmitting the calculated air-to-fuel ratio to an engine control unit in real-time.

Abstract: An electronic engine fuel controller that is simple, low cost, easily installed, and configurable for any internal combustion engine. The system is intended for upgrading older carbureted vehicles or vehicles that have been modified beyond the limits of the OEM controller. It takes advantage of modern micro controller technology with integrated memory, digital input/output, sensor and timer channels to produce a low parts count, as well as reliable operation in a large variety of vehicles, even when installed by people with little experience or knowledge in this area. Operation is by sensing a tachometer signal from the existing distributor, ignition coil, toothed wheel or similar device that produces one electronic pulse for each cylinder cycle. When a pulse is received, software in the micro measures engine operating parameters, calculates fuel parameters, and fires one or more injectors depending on how the system is configured.

Abstract: A drop selection assemblage for use in a printhead and method of making includes a drop generator with a jet array for releasing a drop stream along a normal drop path. The drop stream includes print media drops and recycle drops. The assemblage has a charge structure disposed in a spaced apart relationship to the jet array. The charge structure is a substrate with a non-beveled and beveled portion sloped between 3 degrees and 25 degrees relative to the normal drop path. The charge structure has one or more drop charging electrodes on the non-beveled portion to charge recycle drops and one or more short detection electrodes on the beveled portion. A catcher is located adjacent to the charge structure for catching drops that have passed along the charge structure. The print media drops are selected, and the recycle drops are deflected without either contacting the charge structure.

Abstract: A flexible lamination method is provided for joining primary ink jet components. Essentially, the existing thermosetting construction techniques are replaced with a thermoplastic construction by replacing epoxy with sheet plastic during the lamination process. The flexible lamination joins primary ink jet components. Thermoplastic films have a high viscosity at lamination temperatures. This high viscosity holds bonding material in the area intended by elimination of wicking.
