US Patent:

20190041469, Feb 7, 2019

Filed:

Sep 27, 2018

Appl. No.:

16/144254

Inventors:

- Houston TX, US
Randal Thomas Beste - Katy TX, US
Brian Roberson - The Woodlands TX, US

International Classification:

G01R 33/00
G01R 33/04
G01V 3/26

Abstract:

A magnetic field measurement device includes an excitation circuit including an excitation coil that is coupled to a resonation control circuit. The excitation coil is wound around an amorphous soft magnetic core. The magnetic field measurement device includes a detection circuit including a detection coil that is wound around the amorphous soft magnetic core. The resonation control circuit is coupled to the excitation circuit and to the detection circuit to adjust a resonant frequency of the detection circuit responsive to temperature variations of the amorphous soft magnetic core.

International Classification:

G01R 33/00
G01V 13/00

Abstract:

A reduced-cost apparatus for calibrating the sensitivity and orthogonality of a triaxial magnetometer, and a method for adjusting the distance between the two coils of a Helmholtz coil and other related parameters are described herein. A method can include positioning a calibrated magnetometer within a mounting fixture between two coils of a Helmholtz coil, the two coils arranged in mutually parallel planes and separated by the radius of the Helmholtz coil, the mounting fixture mounted such that a position of the mounting fixture is adjustable along an axis orthogonal to the mutually parallel planes; adjusting the position of the mounting fixture over at least some of the positions and measuring the magnetic field at each position to generate a set of magnetic field measurements associated with the positions; and adjusting the first distance based on the first set of magnetic field measurements. Additional apparatuses, systems, and methods are disclosed.

International Classification:

G01V 13/00
G01V 3/28

Abstract:

Systems for synchronizing downhole subs are disclosed. Some system embodiments may include a first downhole sub including a clock signal generator configured to generate an unmodified clock signal. The first downhole sub may also include a modification circuit configured to modify the clock signal. The system may also include a second downhole sub comprising a phase-locked loop circuit configured to receive as input the modified clock signal and output a second clock signal synchronous with the unmodified clock signal.

Filed:

May 26, 2015

Appl. No.:

14/721542

Inventors:

- Houston TX, US
Randal Thomas Beste - Katy TX, US
Brian Roberson - The Woodlands TX, US

International Classification:

G01R 33/00
G01V 3/26
G01R 33/04

Abstract:

In some embodiments, an apparatus and a system, as well as a method and an article, may include synchronic symmetrical integrator circuitry and a magnetic field measurement device comprising an excitation circuit including an excitation coil, the excitation coil being wound around an amorphous soft magnetic core having a certain temperature coefficient such that inductance of the excitation circuit will change with temperature variations of the amorphous soft magnetic core; a detection circuit including a detection coil, the detection coil being wound around the same amorphous soft magnetic core, such that inductance variation of the detection circuit with temperature of the core can be detected from the excitation coil; and a resonation control circuit coupled to the excitation circuit and to the detection circuit to adjust a resonant frequency of the detection circuit responsive to temperature variations of the core. Additional apparatus, systems, and methods are disclosed.
