Abstract: A control system for an engine includes a distributed control module configured to be associated with a sensor of the engine, a digital link, and a communication control. The distributed control module is connected to the communication control via the digital link. The communication control includes a bus communication engine configured to communicate with the engine control via a bus, and a memory. The memory includes a first buffer that is associated with the distributed control module and a second buffer that is associated with the bus communication engine.

Abstract: A method, system and computer readable medium for implementing and performing a multi-resolution contrast-based dynamic range management algorithm and allowing for the efficient compression of an intensity dynamic range of an input image to a reduced intensity dynamic range of an image display signal. Specifically, the method, system and computer readable medium of the invention comprise decomposing the input image into a plurality of image components, modifying the intensity characteristics of the plurality of image components and reconstructing the plurality of image components into an output image for display on an image display device. In another aspect of the method, system and computer readable medium of the invention, the decomposition of the input image and reconstruction into an output image are performed using a Laplacian pyramid.

Abstract: A method for detecting or sensing zero crossings in a rectified power signal comprising three separate signal constituents for energizing a three-phase circuit is provided. The method includes the steps of sampling at least two consecutive cycles of each signal constituent at a predetermined sampling rate; storing a predetermined number of samples for each signal constituent; computing a respective initial zero crossing estimate for each signal constituent; and checking the accuracy of the respective initial zero crossing estimate for each signal constituent of the power signal. If necessary, the method can further include the step of adjusting the initial estimate for the zero crossing of at least one of the three signal constituents of the power signal. In each case, the detected or sensed zero crossings, in turn, enable detection of a ground fault in the three phase circuit.
