A life indicator for a component of a machine is disclosed. The life indicator includes at least one sensor operably associated with the machine and configured to sense a property associated with the machine. The sensor is configured to output the sensed property as a data signal. The life indicator also includes a memory element having a first data structure that determines a damage factor for the component of the machine based at least in part on the data signal received from the at least one sensor. A processor executes the first data structure to determine the damage factor.

The present disclosure is associated with a user requesting access to the software option associated with a machine, a remote facility receiving the request, authorizing access to the software option, and sending an enabling signal to enable the software. The enabling signal (e.g., a software key) may then be used to access and use the software option. An intermediary may be used to authenticate the enabling signal.

Method and system of enabling a software option on a remote machine

A method and apparatus to monitor ton-miles-per-hour on a plurality of tires on a mobile machine as the mobile machine hauls a load by determining the weight of the load on the tires, determining the ground speed of the mobile machine, and compensating for uneven distribution of the load on the tires. The ton-miles-per-hour is calculated for each tire as a function of the load distribution and the ground speed.

Method and apparatus for monitoring ton-miles-per-hour for tires on a

In one aspect of the present invention, a method for detecting a powerless condition of a reciprocating internal combustion engine is provided. The engine has a plurality of reciprocating components, at least one cylinder and a crankshaft. The method includes the steps of sensing angular velocity of the crankshaft and responsively producing an angular velocity signal and determining a rate of fuel supplied to the one cylinder and responsively producing a fuel rate signal. The method further includes the steps of determining an indicated torque for the one cylinder as a function of the angular velocity signal and the fuel rate signal and responsively producing an indicated torque signal. Further, the method includes the steps of determining a requested torque for the one cylinder as a function of the fuel rate signal and the angular velocity signal and responsively producing a requested torque signal. An indication of powerless of the one cylinder is determined as a function of the requested torque signal and the actual torque signal.
