Portable System For Pzt-Based Inspection Of Bolted Connections
view source -
US Patent:20210356436, Nov 18, 2021
-
Filed:Oct 18, 2019
-
Appl. No.:17/286201
-
Inventors:- Houston TX, US

G01N 29/22 -
Abstract:A portable inspecting device includes PZT transducers and performs active sensing to measure the characteristics of bolted connections. The PZT transducers are mounted on opposing ends of spring-loaded rods and can be moved apart to accommodate a structure for testing. The springs cause the PZT transducers to push against opposing parts of the structure in a stable but temporary fashion. The device can be physically moved to inspect the status and health of multiple different bolted connections.

US Patent:20170292364, Oct 12, 2017
-
Filed:Apr 28, 2016
-
Appl. No.:15/516955
-
Inventors:- Houston TX, US
Batakrishna MANDAL - Missouri City TX, US
Boguslaw WIECEK - Kingwood TX, US
Zheng CHEN - Katy TX, US -
International Classification:E21B 47/08
E21B 44/00 -
Abstract:An example method includes determining a frequency response of a tuned pulse to be transmitted from a transmission element. A matching frequency envelope corresponding to a frequency envelope of the frequency response may be determined. A time domain signal corresponding to the matching frequency envelope may be determined. A series of digital pulses corresponding to the time domain signal may be determined. An analog output at a switching amplifier corresponding to the series of digital pulses may be generated. A transmission element may be excited with the analog output.

US Patent:20170175514, Jun 22, 2017
-
Filed:Apr 28, 2016
-
Appl. No.:15/311636
-
Inventors:- Houston TX, US
Zheng Chen - Katy TX, US
Batakrishna Mandal - Missouri City TX, US -
International Classification:E21B 47/00
H04B 15/02
E21B 47/14 -
Abstract:An example cement and casing evaluation tool includes an amplifier and a filter coupled an output of the amplifier. A transducer may be coupled to the output of the filter. A ringing reduction system may be coupled to at least one of the amplifier, the filter, and the transducer, wherein the ringing reduction system selectively dissipates energy from at least one of the amplifier, the filter, and the transducer in response to a control signal.

International Classification:H03K 17/691
H03K 7/08
H03K 17/74 -
Abstract:A pulse-transformer-based isolated gate driver circuit uses a small count of high-temperature-qualified components to drive a power semiconductor switch with asymmetrical voltage biases. A differential driver generates a pulse signal from a pulse-width-modulated signal, which is passed to a charge and lock circuit through a transformer. The charge and lock circuit includes an activation path and a deactivation path, which are selectively open to current flow based on positive or negative voltage pulses in the pulse signal, to selectively turn the main semiconductor switch on or off. The charge and lock circuit can lock voltage across the main semiconductor switch to keep the main semiconductor switch in an “on” or and “off” state.
