Latest Patents

Akiyama's latest patents include a "Machine fault monitoring apparatus and method." This invention allows for the collection of only the necessary snapshot data required for monitoring faults in machines, such as vehicles. By doing so, it enables more accurate monitoring of faults while reducing the amount of data and memory storage needed at monitoring stations. The apparatus detects various operating parameters, including engine rotational speed, lever operating position, vehicle speed, and tractive force, during machine operation. The fault detection history is updated whenever a fault, such as a drop in engine oil pressure or overheating, is detected. This innovation ensures that only relevant data is transmitted to the monitoring station, optimizing the monitoring process.

Another significant patent is the "Method and apparatus for determining machine maintenance due times." This invention determines maintenance due times based on user-performed in-house maintenance and the occurrence of abnormalities during machine operation. A scoring system is employed, where points are subtracted for detected abnormalities and added for maintenance performed. When the score reaches a prescribed value, it indicates that maintenance is due for the machine component.
