    摘要: An apparatus, configured and operable to determine a state and/or an operation of a powered electrical device, comprises one or more antennas, a receiver operable to receive emission(s) of electromagnetic energy from the electrical device; an illumination device operable to illuminate the electrical device with a pulse of electromagnetic energy; a controller including: one or more processors, a non-transitory computer readable medium comprising executable instructions that, when executed by the one or more processors, cause the one or more processors to perform the steps of selecting a spectral frequency target component of the emission(s), iteratively controlling the illumination device, measuring, at each iteration, a change in characteristic(s) of the spectral frequency target component of the emission(s), assigning a score value to each measurement, and iteratively effecting optimized parameter(s) of the pulse based on the score value until a final score value indicates a desired state, operation of the electrical device.

    摘要: A receiver includes a circuit designed to process, based on a plurality of timed waveform reference locations, a waveform signal, the waveform signal comprising a message. The circuit may include a clock source, an input configured to receive the waveform signal, a time location reference circuit coupled to the clock source, the time location reference circuit designed to output the plurality of timed waveform reference locations, each timed waveform reference location being set by the clock, and a signal processing circuit coupled to the time location reference circuit, the signal processing circuit designed to generate an output voltage in a response to the waveform signal being inputted into the signal processing circuit through the input and processed at each timed waveform reference location from the series of timed waveform reference locations. A transmitter that generates the waveform signal can be also provided where the clocks are matched.

    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.
