    摘要: A robotic apparatus for traversing a selected area autonomously that senses orientation relative to the Earth's magnetic field or other “environmental” signals. The robotic apparatus is provided in two models, a master that can record directive and compass or “environmental signal” readings, or that can record received location information, to provide at least one command recorded on a machine-readable medium representing an instruction for traversing an area of interest, and a slave that lacks the recording capability. Both master and slave models can replay recorded commands, and compare the expected orientation from the command with an actual orientation sensed during autonomous operation. If an error exceeding a predetermined value is observed, a corrective action is taken. The robotic apparatus is able to utilize a tool to perform a task at one or more locations, such as cutting, shoveling and digging. In one embodiment, the robotic apparatus is a lawn mower.

    摘要: A method and system for identifying or determining degradation in performance of an engine cooling subsystem having an electric motor for powering a fan in a locomotive is provided. The method allows for monitoring a signal indicative of an electrical imbalance in one or more phases in the fan motor of the cooling subsystem, and for adjusting the value of the monitored signal for deviations from an estimated nominal phase signal value due to predetermined external variables so as to generate an adjusted phase signal value. The method further allows for comparing the value of the adjusted phase signal value against the nominal phase signal value to determine the performance of the cooling subsystem.
