  • Patent number: 12146953
    Abstract: Some embodiments relate to the application of a system and a signal processing method for data acquired from a Scanning Acoustic Microscope (SAM) to obtain a high axial resolution and enhanced imaging. The SAM is one of ultrasound imaging methods used for NDE. Embodiments may provide methods for decreasing or reducing the duration (width) of the pulses scattered/reflected by multiple objects/scatters. Such embodiments can accomplish this by eliminating, or at least partially eliminating, the background noise by deconvolving the system responses (i.e., reference signals) obtained from either theoretical modeling or experimental acquiring. In one embodiment, the method minimizes the pulse duration by using a regression technique to predict the spectra responses outside a frequency band.

  • Publication number: 20230083820
    Abstract: The embodiments disclose a pulsed power generator system that can include a cantilever comprising a cantilever tip disposed on a lower surface of a first end and a permanent magnet mounted on an upper surface of the first end, wherein the cantilever is connected to an electric circuit at a second end, an electromagnet generating a time varying periodic magnetic flux, wherein the magnetic flux interacts with the permanent magnet to generate a direction-changing mechanical force that drives oscillation in the cantilever, a conducting pad, disposed adjacent to the bottom surface of the first end of the cantilever and configured so that the cantilever tip can contact the conducting pad. An oscillation of the cantilever causes the cantilever tip to periodically contact the conducting pad forming an electrical switch suitable for pulse generation through the electric circuit.

  • Patent number: 11509285
    Abstract: A sensor system that combines the sensing application of surface acoustic wave (SAW) sensor and sensor signal transfer though the enclosure wall via acoustic means. The sensor system includes SAW sensor placed inside the enclosure and at least one pair of bulk acoustic wave (BAW) transducers, one mounted inside and second outside the enclosure wall, allowing the interrogation of SAW sensor from outside the enclosure. The external BAW transducer converts interrogation electrical pulse into acoustic pulse which travels though the enclosure wall to the internal BAW transducer. The internal BAW transducer converts the interrogation electrical pulse to electrical pulse and transfers it to SAW sensor. The response of the SAW transducer containing series of electric pulses is converted to the series of acoustic pulses by internal BAW transducer which propagates though enclosure wall.

  • Patent number: 11509145
    Abstract: The present disclosure relates to methods and systems for management and control of interconnected energy storage modules, such as battery packs, that can form a larger energy storage system. The disclosure also relates to methods and system for the measurement of cell impedances in a battery pack in-situ and on-line and using active balancing circuits that may already be present in the battery pack. The methods and systems can inject disturbances of different frequencies and measure impedance by using the active balancing circuits present in the battery pack, which can transform an active balancer into a dual active balancer and impedance measurement system. The speed up of impedance measurement energy storage modules can be accomplished by using multi-tone, orthogonal or spread spectrum waveforms applied simultaneously on all or a sub-set of the active balancer circuits in an active balancer.

  • Publication number: 20220241819
    Abstract: The embodiments disclose an ultrasonic transducer that can require a piezoelectric element attached to the transducer to be constantly under high pressure, and this required pressure can be provided and maintained by the transducer's design at all temperatures during its operation. The exemplary ultrasonic transducer can eliminate a failure of the bond between the piezoelectric element and a delay block by using the mechanical structure to hold all components in place while permitting the piezoelectric transducer to generate pulses of the desired frequency, frequency bandwidth, and pulse width without undesired echoes and/or attenuations.
