Abstract:
The present invention is a method and system for controlling a motor attached to a variable displacement pump for providing a supercritical fuel and fuel pressure to a plurality of fuel injectors of a vehicle engine. The system includes: a pump having a motor; a tachometer sensor for measuring a rotational displacement of a motor shaft and for sending a tachometer count value to a memory device; an engine control unit configured to generate a rotational displacement vs. pressure profile of the pump based on the displacement value and pressure value; an accumulator attached to the output of the pump; and a control method that allows for a look ahead and prediction of the pump requirements needed in a future cycle based on current demand to allow for an efficient fuel injection pump.
Abstract:
An apparatus for supplying a two-component, electrically conductive coating material which includes a first flow path for supplying a metered quantity of a catalyst from a source to a mixing device, a second flow path for applying a metered quantity of resin from a source to the mixing device, a third flow path for transferring the resulting two-component coating material from the mixing device to at least one coating dispenser which discharges electrostatically charged coating material onto a substrate, and, at least one voltage block device for maintaining a continuous voltage block between the electrostatically charged coating material and the sources of catalyst and resin.
Abstract:
An inkjet printing system having a replaceable set of ink-related components which are installed together and replaced together as a single ink delivery system for each different color of ink. The set includes an ink printhead cartridge with an inlet port, an ink supply module, and a printhead service module, each of which is manually mountable by a user onto an inkjet printer. The ink supply module contains enough ink to completely replenish an entire printhead reservoir several times before the expected useful life of the printhead cartridge has expired, at which time a user can replace the entire set of ink-related components for a particular color. Similarly, the printhead service module is designed for reliable performance for the expected useful life of the printhead cartridge. This system enables the entire ink delivery system to be replaced for different printing needs, such as replacing indoor dye-based inks with outdoor pigment based inks.
