Assignee/Applicant Baker Hughes Link(s) to Patent US Patent Patent Title Methods for measuring and modeling the process of prestressing concrete during tensioning/detensioning based on electronic dista Patent Number & Issued Date US 10203268 February 12, 2019 Inventor Names David H. Parker*, John M.

Second, a calculation is performed to determine the input delay(s) between the pulses that would produce desired output delay(s). For example, it may be desirable that the pulses arrive at the respective remote ends at the same time, in which case the desired output delay(s) is (are) zero. Third, the same speedy delivery pulses are transmitted onto the respective cables so that the interpulse delay(s) conform to the computed input delay(s). Thus, the desired output delay(s) are achieved at the remote ends of the cables. Assignee/Applicant Board of Regents, University of Texas System Link(s) to Patent US Patent Patent Title Three-Dimensaional Holographical Imaging Patent Number & Issued Date Australian 2013337368 September 22, 2016 Inventor Names Mohammad Tayeb Ghasr*, and Reza Zoughi* *indicates IMS member Abstract A holographic imaging system including a transmission line coupled to an antenna at one end and to a signal source at another end. The antenna defines an aperture through which a signal generated by the signal source is transmitted incident to an object located remotely from the aperture and through which a signal reflected from the object is received by the antenna aperture. A standing wave probe phase-referenced to the antenna aperture samples the reflected signal. A detector connected to the standing wave probe receives the sampled reflected signal and provides an output signal that represents a real-valued signal proportional to an in-phase component of the reflected signal from the object. A processor executes an imaging algorithm for generating a multi-dimen sional profile representative of the object based on the output signal from the detector. Assignee/Applicant The Curators of the University of Missouri, Columbia, MO (US) Link(s) to Patent Australian Patent Patent Title Waveguide Probe for Nondestructive Material Characterization Patent Number & Issued Date US 9,482,626 November 1, 2016 Inventor Names Mohammad Tayeb Ghasr*, M. Kempin, and Reza Zoughi* *indicates IMS member Abstract An open-ended waveguide probe including a finite flange extending outwardly and functioning as an infinite flange. A signal source provides a microwave signal to the waveguide, which in turn transmits microwave electromagnetic energy incident upon an object to be tested. The finite flange at the waveguide's aperture is shaped to reduce scattering of the electromagnetic field reflected from the object and received by the aperture. The probe is adapted for coupling to a receiver for sampling the reflected electromagnetic field received by the aperture and the receiver is adapted for coupling to a processor for determining at least one material characteristic of the object based on sampled electromagnetic field reflected from the object.

Assignee/Applicant Michelin Recherche Et Technique S.A., Compagne Generale Des Etablissements Michelin, France Link(s) to Patent US Patent Patent Title Measurement While Drilling Spontaneous Potential Indicator Using Differential Magnetometers Patent Number & Issued Date US 9,411,065 August 9, 2016 Inventor Names Robert A. Estes* *indicates IMS member Abstract A drilling system, method and drilling apparatus for determining a parameter of a formation at a downhole location is disclosed. A member having a longitudinal axis is disposed in a borehole at the downhole location. A first magnetometer and a second magnetometer are disposed at an axial location of the member as separate azimuthal locations around the member and oriented tangential to a circumference of circle in a plane transverse to a longitudinal axis of the member. Magnetic fields resulting from a current flowing longitudinally through the member due to a spontaneous potential in the formation are measured to determine the spontaneous potential. The parameter of the formation is determined from the determined spontaneous potential. Assignee/Applicant Baker Hughes Incorporated Link(s) to Patent US Patent Patent Title High-reliability holdover method and topologies Patent Number & Issued Date US 9362926 June 7, 2016 Inventor Names William J. Dickerson*, Robert T. Dickerson Abstract System and methods for a clock system disciplined to an external reference. In one embodiment, the clock includes a flywheel oscillator controlled by the external reference and a free running holdover oscillator.

Assignee/Applicant Itron, Inc. Link(s) to Patent US Patent Patent Title Detection of Electromagnetic Field with Electroactive Polymers Patent Number & Issued Date US 9,804,216 October 31, 2016 Inventor Names S. Connor, M. Cracraft*, J. Jackson, J. Kuczynski Abstract Embodiments relate to a method, apparatus, and system for passively detecting strength of an electromagnetic field. An electroactive polymer (EAP) is configured with an antenna in communication with an RC circuit. The EAP is positioned proximal to a sensor. In response to receipt of a transient electromagnetic pulse due to an electrostatic discharge, the circuit captures the received pulse and transmits the pulse to the EAP. The EAP reacts to the pulse in the form of a deflection. The magnitude of the deflection correlates to the field strength which caused the received pulse. As deflection of the EAP is communicated to the proximally positioned sensor, a recording of the electrostatic discharge takes place.
