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.

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.

Abstract: The present technology is directed to providing fault management with dynamic restricted access in a tenant network. The tenant network can be a private 5G cellular network or other wireless communication network. The present technology can identify a fault event within the tenant network based on received telemetry data, associate the fault event with a vendor component included in the tenant network, and generate a vendor fault context. The vendor fault context can be generated to include only the portion of telemetry data that is determined to be related to the fault event or the vendor component. The present technology can further use the vendor fault context to create a time-bound user account for remotely accessing the tenant network for fault triage and management. The time-bound user account can be associated to a static role-based access control (RBAC) scheme configured with access restrictions determined based on the vendor fault context.

Abstract: A method for the regeneration of effluent from an absorber capturing emissions of carbon dioxide (CO2) from industrial sources. Reducing CO2 emissions from all sources is a key objective of most nations, and every industrial source of CO2 emissions has received extensive scrutiny. The method involves designing and installing on a source a proprietary thermal regeneration system for a sorbent used in the CO2 capture equipment system, which recirculates the sorbent liquid through an absorption column (absorber). Because sorbents used in these systems are expensive, it would be useful if the spent sorbent following absorption of CO2 is regenerated for re-use in the absorber. The present invention's regeneration method uses thermal swing (changes in temperature of the spent sorbent), and describes the integration of a waste heat recovery process into the thermal swing method.

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.
