Patent ID: 11906575
Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 9:
10. An electrical power analyzer, comprising:
a voltage measurement module configured to measure voltages of lead pairs connected to respective prongs of an electrical plug and to output analog waveform data streams of a device;
a sampler and digitizer configured to generate a current power draw signature of the device based on received analog waveform data streams output from the voltage measurement module, and to digitize the analog waveform data streams;
a memory configured to store the digitized waveform streams; and
a communications module including a buffer, the communications module configured to receive and output the digitized waveform data streams; and
a processor configured to compare the current power draw signature of the digitized waveform streams received from the communications module with a known power draw signature of the device, and to generate a warning in response to a determination that the waveform data streams include at least one of an anomaly or artifact.
