A method for detecting defects in a rotational element of a machine based on changes in measured vibration energy includes: (a) collecting vibration data over an extended period of time using vibration sensors attached to the machine; (b) processing the vibration data to generate a time waveform comprising processed vibration values sampled during sequential sampling time intervals within the extended period of time; (c) detecting multiple time blocks within the extended period of time during which the processed vibration values exhibit sustained increases at progressively increasing rates; and (d) generating alerts based on detection of the multiple time blocks during which the processed vibration values exhibit sustained increases at progressively increasing rates. The multiple time blocks may include a first time block during which the processed vibration values increase at a first rate, and a second time block occurring after the first time block during which the processed vibration values increase at a second rate that is greater than the first rate.

An information processing system includes a terminal apparatus that sends the received machine-type identification information and state history information received from the monitoring target apparatus by near field communication, an information processing apparatus that receives the machine-type identification information and the state history information from the terminal apparatus, and a storage apparatus that accumulates machine-type identification information identifying a machine type of a monitoring target apparatus and normal-state history information in an associated manner. When the information processing apparatus receives the machine-type identification information and state history information about a certain monitoring target apparatus from the terminal apparatus, the information processing apparatus compares the normal-state history information accumulated in the storage apparatus in association with the machine-type identification information and the received state history information, judges whether an operation state of the monitoring target apparatus is normal, and sends a judgment result to the terminal apparatus.

A system, method, and computer-readable medium are disclosed for attesting determining computer system fan usage and maintenance. A determination is made as to the architectural diagram or layout of a computer system. The diagram or layout shows components and fans that support the components. The architectural diagram or layout, where each virtual section shows a fan and the components. Operational load is determined for each virtual section over a period of time. A threshold value for particular periods to time, where the threshold value either is to low load periods or as to periods to increase or decrease speed of the fan to address operational load of the components.

A method for determining part wear, such as using a wear model, includes receiving, from a sensor, sensor data representing a surface of a wear part. The method further includes determining an estimated time until the part should be replaced. The method further includes batching together multiple wear parts that need replacing to enable a user to replace multiple parts in one maintenance period. The method may also include providing information to the user during replacement of a worn part to indicate the part location.
