Patent number: 11119209Abstract: A first method includes receiving a first reflected radar signal from a target in a first field of view and receiving a second reflected radar signal from a target in a second field of view offset from the first field of view by a predetermined distance; transforming the first and second reflected radar signals to obtain first and second sets of frequency coefficients, from which a frequency-dependent phase difference is obtained; and calculating a time-delay from the slope of the frequency dependence. A second method includes obtaining summed difference values between the first and second radar responses, where each of the summed difference values corresponds to different time shifts between the first and second radar response, and deriving from the summed difference values a time-delay associated with the target's motion from the first field of view to the second field of view. A third method combines the time-delays or associated speeds obtained from independent estimators.Type: GrantFiled: April 29, 2019Date of Patent: September 14, 2021Assignee: Houston Radar LLCInventors: Sergei Sharonov, Brian Hill, Vipin Malik, Stanley J.

Patent number: 7336199Abstract: An inductive coupling system including a mandrel and an inner sleeve and outer housing that surround and rotate relative to the mandrel. The system also includes a mandrel electronics system and a housing electronics system that communicate electronically using a mandrel inductive coupler and a housing inductive coupler. The mandrel electronics system may also communicate with equipment on the surface. Alternatively, the system may include a mandrel and first and second mandrel electronics systems in different mandrel sections. The first and second mandrel electronics systems communicate electronically using a mandrel inductive coupler. Also alternatively, the system may include a mandrel and an inner sleeve and outer housing that surround and rotate relative to the mandrel. The system also includes a mandrel electronics system and a housing electronics system that communicate electronically using a housing inductive coupler.Type: GrantFiled: April 28, 2006Date of Patent: February 26, 2008Assignee: Halliburton Energy Services, IncInventors: Jeffrey B.

Patent number: 7307425Abstract: A resistivity tool includes receiver electronics near each receiver antenna loop. Placement of the electronics in this position such as at the circuit card between the terminal ends of the receiver antenna loop improves signal to noise ratio by reducing or eliminating interference, noise, and cross-talk of transmissions from the receiver to a remote microprocessor. By using material such as silicon-on-sapphire, electronics can be miniaturized and operate reliably at when exposed to high temperatures, even for long periods.Type: GrantFiled: November 18, 2004Date of Patent: December 11, 2007Assignee: Halliburton Energy Services, Inc.Inventors: James J.

Patent number: 6429926Abstract: An optical design for delivering or receiving light from a fluid being measured is disclosed. The optical design is capable of immersion in the fluid being measured, and is capable of operating with fluids that have a different index of refraction. The optical design includes a solid prism of optical material to which a fiber optic attaches by a suitable adhesive. In an optical delivery system, light from the fiber enters the prism and reflects off an internal mirror to a second internal reflective surface. The second internal reflective surface focuses the light to a fixed point through an exit surface of the prism. The second internal reflective surface may in the shape of an ellipse, or may comprise a diffractive surface. The exit surface has a spherical concave shape that is centered on the fixed point where the light is focused, so that light passes through the exit surface at substantially ninety degrees.Type: GrantFiled: January 8, 2001Date of Patent: August 6, 2002Assignee: Nova Gas Transmission Ltd.Inventors: Ian D. Williamson, Sergei A. Sharonov, Pierre-Jean Daniel, Darwin E. Kiel
