Abstract: A machine may comprise a piston; a memory; and an electronic control module. The electronic control module may be configured to obtain information identifying a previous amount of wear of the piston ring and information identifying an initial dimension of a coating of the piston ring; determine a piston ring wear rate based on a cylinder pressure associated with the piston; determine an amount of time between a current time and a time when the previous wear of the piston ring was calculated; calculate a current amount of wear of the piston ring based on the previous amount of wear of the piston ring, the amount of time, and the piston ring wear rate; calculate an amount of damage to the piston ring based on the current amount of wear and the initial dimension; and take a remedial action when the amount of damage exceeds a threshold.

Abstract: A communication network is arranged in a ring configuration of network elements (12) coupled by working spans (16) associated protection spans (18), with multiple rings sharing network elements (12a and 12b). A shared protection span (18ab) is coupled between pairs of shared network elements (12a and 12b). A matrix 28 in a shared network element (12a or 12b) can couple any channel from one of the incoming working spans or protection spans to any channel of the shared protection span (18ab).

Abstract: A communication network using a ring structure incorporates shared protection channels (22ab, 22bc, 22bd) to reduce costs in implementing protection spans. The shared protection network elements (12a, 12b, 12c, 12d) use a protocol of conventional messaging to integrate with traditional fully redundant network elements.

Abstract: A system, method and computer program product for automated voice recognition using the barge-in time of a user's utterance is provided. A list of items is audibly provided to a user. The user selects one item from the list by providing an utterance representing the user's selection. The utterance time (i.e., the barge-in time) is calculated from the utterance of the user. Then, the utterance is compared to each item in the list so as to generate a confidence score for each item in the list, with the confidence score being based on the similarity between the item and the utterance. The confidence scores are also based on the barge-in time. One of the items from the list is selected based on the confidence scores of the items.

Abstract: An electronic digital control system monitors and controls the operation of an engine fueling system. Signals activating injection for a plurality of cylinders are transmitted through a single line to a driving circuit for a single injector solenoid valve, while signals controlling accumulator fuel pumps are transmitted to pumping control solenoids. Injection signals are controlled to vary fuel delivery rate during an injection event. A back EMF sensing circuit measures valve opening delay and the control system compensates for valve delay. Variable cylinder-specific delays in the injection solenoid output signal pulses are programmed to compensate for a varying fuel line length to each injector nozzle. At startup, the control system pulses the pumping control solenoids to begin pressurizing the accumulator before engine angular position sensors provide an accurate indication of engine angular position to allow precise timed control of the pump.
