Abstract: Interfaces are provided which integrate mistake-proofing concepts in a way easily understandable by the operator and easily configured by a manufacturing engineer. As mistake-proofing concepts are developed tables are populated and associated with specific assembly processes. Sensors are employed to monitor parts selection and tool usage. Sensors used for tool use and parts selection, error messages and actions to be performed or monitored are all defined and related in the tables and in turn to specific assembly orders. The tables are also populated with logic pointers, which are referenced by a Process Logic Control (PLC) unit that has been programmed to recall and carry out infinitely variable monitoring or control of the assembly process. For example when a particular order has been identified to the PLC by way of a scanned barcode or other means, a bill of material and assembly sequence is provided to the operator by appropriate means such as a CRT monitor.

Abstract: Computerized method and system computerized method for guiding equipment service personnel while at an equipment work site through a plurality of tasks for troubleshooting the health of a selected system of a selected equipment to determine the nature and extent of service needed for such system. The method allows to provide a database comprising detailed data for health assessment and servicing of a selected equipment and system thereof, and an expert rule-based troubleshooting wizard for eliciting information regarding the selected equipment and system and for providing troubleshooting instructions to determine the nature of the equipment fault and the servicing required for the selected equipment and system. An input/output device at the work site for communicating with the database is provided. The method allows to select the equipment and the system thereof to be serviced and to access the database to interface with the troubleshooting wizard for the selected equipment and system.

Abstract: A HEUI system uses a fixed displacement, axial displacement pump to provide a generally constant pump flow of high pressure hydraulic fluid over the operating speed range of the pump to minimize parasitic power drains on the engine. The axial piston pump includes a orificing suction slot to vary the pump displacement over the operating speed of the pump. A throttling valve at the pump inlet may be provided to starve inlet fluid feed if reduced flow to the injectors is additionally required.
