    摘要: A hand-held apparatus for analysis, testing, inspecting and/or screening a fully integrated and assembled electrically powered assets and devices for measurement of degree of device aging, degradation, condition, and/or Remaining Useful Life (RUL). The device includes an on-board antenna positioned at a distance from the electrically powered device under test and a signal receiver or sensor for examining a signal from the electrically powered device, but especially applied to electronic devices. The receiver or sensor collects unintended and/or intended RF energy components emitted by the electrically powered device and performs the above analysis in a response to the acquired signal input while the electrically powered device is active or powered.

    摘要: The present invention is a signal processing method to significantly improve the detection and identification of source emissions. More particularly, the present invention offers a processing method to reduce the false alarm rate of systems which remotely detect and identify the presence of electronic devices through an analysis of a received spectrum the devices' unintended emissions. The invention identifies candidate emission elements and determines their validity based on a frequency and phase association with other emissions present in the received spectrum. The invention compares the measured phase and frequency data of the emissions with a software solution of the theoretically or empirically derived closed-form expression which governs the phase and frequency distribution of the emissions within the source. Verification of this relationship serves to dramatically increase the confidence of the detection.

    摘要: An apparatus for a network of electrical and/or electronic devices coupled to a data bus comprises a sensor coupled to the data bus and configured to capture information content communicated through the data bus in a form of electromagnetic emissions being at least one of differential mode electromagnetic emissions, common mode electromagnetic emissions, coupled radiated electromagnetic emissions, and data bit streams; one or more processors or logic devices, and a non-transitory computational medium comprising executable instructions. The apparatus measure a feature value in at least one region of a time domain or a frequency domain of the captured electromagnetic emissions, calculates a difference value between the measured feature value and one or more baseline feature values, and determines, based on the calculated value, a presence or an absence of anomalies indicative of at least one of cyber intrusion attempt, cyber attack, cyber-physical attacks, malware, etc.

    摘要: A diagnostic apparatus for analysis, testing, inspecting and/or screening an integrated and assembled electrically powered equipment rack and its populated cards and devices for measurement of degree of device aging, improper operation, degradation, condition, and/or Remaining Useful Life (RUL). The device includes an antenna card with a detachably attachable antenna module that can be positioned at a distance from the electrically devices under test and a signal receiver or sensor for examining a signal from the electrically powered device, but especially applied to rackmount supported electronics and/or chassis based electronics. The receiver or sensor collects unintended and/or intended RF energy components emitted by the electrically powered device and performs the above analysis in a response to the acquired signal input while the electrically powered device is active or powered.
