Abstract: A transducer system with transducer and circuitry for applying a pulse train at a single frequency to excite the transducer. The transducer is operable to receive an echo waveform in response to the pulse train. The system also comprises circuitry for determining a time of flight as between a first reference time associated with the pulse train and a second reference time associated with the echo waveform.

Abstract: Methods and apparatus to measure and analyze vibration signatures are disclosed. In some examples, a meter is provided comprising a waveform generator to generate a waveform based on first distance measurements of an object. In some examples, the meter includes a waveform generator to determine a first vibration characteristic of the object based on the waveform. In some examples, the meter includes a comparator to compare the first vibration characteristic to a signature vibration characteristic of the object, the signature vibration characteristic of the object indicative of normal characteristics of the object. In some examples, the meter includes a reporter to, in response to determining the first vibration characteristic does not match the signature vibration characteristic, generate an alert.

Abstract: A frequency modulated continuous wave (FMCW) radar system that includes a transceiver coupled to an analog to digital converter (ADC), and a digital signal processor (DSP) coupled to the ADC. The transceiver is configured to transmit a plurality of FMCW chirps, receive a plurality of reflected FMCW chirps, and mix the plurality of reflected FMCW chirps with at least one of the FMCW chirps to generate a plurality of beat signals. The reflected FMCW chirps are the FMCW chirps after being reflected off of a target object. The ADC is configured to convert the beat signals into a plurality of digital chirps. The DSP is configured to receive the digital chirps and quantify a plurality of vibration parameters for the target object based on a comparison of phase information in a frequency domain between one of the plurality of FMCW chirps and one of the plurality of digital chirps.
