  • Compensating for acceleration induced inclination errors
    Patent number: 9618338
    Abstract: A relative angle between a machine's direction of travel and the orientation of an inclination sensor on a work tool coupled to the machine is determined and/or calculated. In some examples, the present disclosure describes a method of determining a relative angle between a machine's direction of travel and an inclination sensor coupled to a work tool coupled to the machine. Such method may include determining the machine's direction of travel, and determining an orientation of the inclination sensor coupled to the work tool coupled to the machine. The relative angle between the machine's direction of travel and the orientation of the inclination sensor coupled to the work tool may then be calculated.

  • Prioritizing Method of Operator Coaching On Industrial Machines
    Publication number: 20150004574
    Abstract: A system and method for coaching an operator of an industrial machine improves operator skill levels by providing prioritized coaching to the operator. The system and method identify operations performed during the work session and compare each operation to a model of the operation to identify operations that differ substantially from the model. Each such operation is logged as a coaching opportunity, and the method and system prioritize the associated coaching sequences for presentation to the operator, e.g., based on (1) classification of the operation associated with each coaching opportunity; (2) significance of the operation associated with each coaching opportunity; (3) operator history; (4) manager preferences; and (5) error severity.
