Abstract: A method for detecting and monitoring a signal includes: detecting an alignment point for a periodic signal segment of a periodic signal generated by an apparatus being monitored for standard functionality; activating the apparatus from a period prior to the alignment point to an end point of the periodic signal segment; locating a first point of the periodic signal segment; and locating a second point of an additional periodic signal segment. The method further comprises: determining a lowest point of the periodic segment; determining a difference feature between the first and second points; determining a minimum angle between the first and second points; analyzing the lowest point with respect to the difference feature and minimum angle; and normalizing the periodic signal in response to locating the first and second points. The signal may be a pressure of a water pump, a sound or vibration of an engine, or a distance signal of gear engagement. These may be used to judge the health or running state of the apparatus.

Abstract: Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: obtaining movement path data that specifies a location of a mobile article over time within a geographical area having an infrastructure feature; determining by machine logic based on map data and based on the movement path data calibrated location data of the mobile article, wherein the determining based on map data and based on the movement path data calibrated location data of the mobile article includes using map data that specifies coordinate location data of the infrastructure feature; and providing one or more output based on the determining.
