  • Publication number: 20140000363
    Abstract: A method by which a vehicle wheel service system, having at least one load roller for applying a generally radial load to a wheel assembly mounted on a driven spindle shaft during rotation thereof, provides a measurement which is representative of the loaded rolling resistance of the wheel assembly undergoing testing. In order to rotationally drive the spindle shaft with the vehicle wheel assembly mounted there on, energy is supplied to a drive motor operatively coupled to rotationally drive the spindle shaft. By monitoring the amount of energy or drive torque required to rotationally drive the spindle shaft and achieve and maintain a desired rotational speed for the wheel assembly when engaged with the load roller, a measurement which is related to the loaded rolling resistance of the wheel assembly is obtained by the vehicle wheel balancing system.

  • Patent number: 6263322
    Abstract: An integrated automotive repair shop network is designed to greatly enhance the efficiency and quality of diagnostic and repair work performed in an automotive repair shop. The network employs a data entry terminal for the entry of routine customer information into a shop management system, including the identification of the vehicle to undergo diagnosis or repair. The shop management system is configured to generate an appropriate repair order. Computerized diagnostic and repair devices linked through the network to the shop management system are configured to access the customer information contained in the repair orders, as well as to extract relevant technical specifications, service bulletins, parts listings, and prior services records from interconnected information databases.

  • Patent number: 5987135
    Abstract: A system and method for controlling and monitoring remote distributed processing systems from one or more control processing systems by downloading agent-application programs from the control processing systems to remote control middleware modules on the distributed processing systems, where the control processing systems have a library of available agent-application(s). The agent-application(s) are compiled by or at the direction of the remote control middleware and executed within operational parameters determined by the control processing systems.

  • Patent number: 5910903
    Abstract: A method and apparatus for verifying, analyzing and optimizing a distributed simulation conducted on one or more simulation components from one or more control computers where the present invention may be overlaid onto a distributed simulation as may be conducted by technologies now known for conducting such simulations, where each simulation component has simulator middleware which is operatively connected to a control computer and where the control computer has agent-applications which it may send to the simulator middleware of one or more selected simulation components to perform a task such as gathering data about a simulation entity and return that data to the control computer for subsequent analysis such as calculating average characteristics or effectiveness of simulation components and having tools for optimizing the distributed simulation by modifying or creating agent-applications to send to selected simulators which change the parameters of the distributed simulation and re-run the distributed simu
