  • Patent number: 8447568
    Abstract: A system and method for analyzing and providing exception-based reports for machine data. The machine data is relayed to a remote system for automated analysis based on tests and parameters defined by an owner. If any exceptions are detected in the data based on the operator-defined input, output is generated. The output may take the form of exception-based printed or electronic reports, or the exception information may be relayed to a hand held device, preferably maintained by service personnel at the work site.
    Type: Grant
    Filed: September 6, 2011
    Date of Patent: May 21, 2013
    Assignee: Caterpillar Inc.

  • Patent number: 6842680
    Abstract: The present invention provides a method and apparatus to automatically control the speed of a work machine 10 based on ton-miles-per-hour limit of at least one of a plurality of tires 12. A vehicle information system 28 having a processor 32 and a database 34 monitors an actual ton-miles-per-hour calculation of the plurality of tires 12. The vehicle information system 28 functions in combination with an electronic control module 66 of the machine 10 to trigger an automatic speed reduction should the actual ton-miles-per-hour rating exceed a predetermined limit. The speed reduction may be affected by at least one of reducing a throttle setting, changing a transmission gear and automatic application of the machine brakes.

  • Patent number: 5868116
    Abstract: An apparatus and method for reducing white smoke during start up of a compression ignition engine is disclosed. The apparatus includes an engine cylinder, a fuel injector, an engine speed sensor, and a microprocessor. The microprocessor preferably includes an engine speed controller that governs the engine speed to a desired value. The microprocessor issues a first fueling level corresponding to a difference between an actual engine speed and the desired engine speed signal. The microprocessor quits fueling the engine cylinder then determines a second fueling level. A determination about whether the cylinder is firing is then based on a comparison between the first and the second fueling level.
