Abstract: A method is provided for determining a global mask value for filtering incoming messages in a CAN environment having a predetermined number of match registers, where the global mask value has one or more bits. A set of incoming messages to be identified is established. Each of the one or more bits in the global mask value is set to a first digital value. The following steps are repeated until the set of incoming messages to be identified fits within a predetermined number of match registers: adding a don't_care bit to the global mask value and determining a best position for the added don't_care bit. The don't_care bit is represented by a second digital value in the best position.

Abstract: The present invention provides calixpyrrole, calixpyridinopyrrole, and calixpyridine macrocycles, having 4, 5, 6, 7, or 8 heterocyclic rings, as well as syntheses, derivatives, conjugates, multimers, and solid supports thereof. Such macrocycles have proved to be effective and selective ion- and neutral molecule-binding agents forming supramolecular ensembles, and ion- and neutral molecule-separation agents. The macrocycles are fully meso-non-hydrogen-substituted porphyrinogens, a few molecules of which were previously known but not recognized as possessing anion- or molecule-binding properties. The binding mode is noncovalent, primarily that of hydrogen-bonding, thereby providing a new mode for liquid chromatography, that of Hydrogen Bonding Liquid Chromatography. Further useful applications of the macrocycles provided herein include environmental remediation by removal of undesired ions or neutral molecules, and removal of phosphate for kidney dialysis.

A haul vehicle identification signal is produced from the reading, and compared to customer data files 125. A load command signal, containing selected information from the customer data file 125 that corresponds with the haul vehicle identification signal, is produced.

Abstract: An apparatus for controllably moving a work implement is disclosed. The implement is connected to a work machine and is moveable in response to operation of a hydraulic cylinder. The apparatus includes an operator controlled joystick. A joystick position sensor senses the position of the joystick and responsively generates an operator command signal. An implement position sensor senses the position of the work implement and responsively produces an implement position signal. A microprocessor based controller receives the implement position and operator command signals, modifies the operator command signal, and produces an electrical valve signal in response to the modified operator command signal. An electrohydraulic valve receives the electrical valve signal, and controllably provides hydraulic fluid flow to the hydraulic cylinder in response to a magnitude of the electrical valve signal.
