US Patent 11402258 Detecting machine action using a machine action detection system

A method and system to detect a plurality of device activities of a device using a device activity monitoring system has been described. The device monitoring activity system includes a vibration sensor in electronic communication with the device to detect vibration of the device. An interrupt counter in communication with the vibration sensor to measure a count of vibration detected by the vibration sensor within a pre-determined period. A storage unit in electronic communication with the interrupt counter to store the count of vibration. A controller in electronic communication with the vibration sensor and the storage unit to determine a mapping between the measured count and one of the plurality of device activities. A transmitter in electronic communication with the controller to autonomously transmit an output signal when the controller determines the mapped one of the plurality of device activities.
