Abstract: A low-powered sensor, a method for a low-powered sensor, and an apparatus are provided for monitoring a condition of a machine. Responsive to receiving a trigger signal during a setup phase, the low-powered sensor collects sensor data for a predetermined extended period of time. The low-powered sensor receives a setting of a delay based on a determined amount of time of the predetermined extended period of time, since the receiving of the trigger signal, for the machine to reach a steady operating condition within predetermined limits. Upon receiving the trigger signal after the receiving of the setting of the delay, the low-powered sensor waits a period of time of the set delay before collecting the sensor data for a predetermined amount of time that is shorter than the predetermined extended period of time, and provides the collected sensor data to a computing device for analysis.

Abstract: Parameter settings and operational data are received from machines for a current predefined time interval. For each machine, a corresponding health metric value is calculated based on the received operational data and machine health data, and stored in association with the received corresponding parameter settings. Associated unknown health metric values are estimated for machines associated with combinations of parameter settings different from the received parameter settings having at least one of the combinations of parameter settings with an associated previously determined health metric value, and at least one other of the combinations of parameter settings with the associated unknown health metric value, based on the corresponding calculated health metric value and the corresponding previously determined health metric value.

Abstract: A computer-implemented method, a system, and at least one computer-readable storage device are provided. A measured value related to operation of a device is periodically received for each respective reporting period. If the measured value indicates unhealthy operation of the device, a distance of the measured value from a predetermined abnormal threshold is determined and stored in a data store. Based on the determined distance, a number of most recent reporting periods included in a window is determined. All stored distances determined from measured values received before the window of the most recent reporting periods are deleted from the data store. An occurrence of a device failure is determined based on the stored distances in the data store after the deleting. In response to determining the occurrence of the device failure, an action is performed.

Abstract: A compression method for resource constrained local area networks (LANs) of an Industrial Internet of Things (IoT) reduces the volume of raw data sent from “Things” to connection points on the LAN. Applications include industrial processes, and typically include multiple sensor nodes. Sensors on machines wirelessly send data to a base station using a wireless LAN. A computer or server in communication with the wireless LAN computes the health of a machine based on the data received. The method operates by taking advantage of unique similarities between sequential groups of certain types of data that can be sent on the LAN. Mathematical operations are performed on the baseline and subsequent data sets to determine similarities. A difference is taken between the baseline and subsequent data sets, and this difference is compressed and sent to the base station where the original data is reconstructed using the baseline data and uncompressed difference data.
