Patent number: 9632071Abstract: A device is presented. The device includes an electromagnetic guiding device to provide electromagnetic radiation, a reflector that reflects a portion of the electromagnetic radiation to generate a reflected portion of the electromagnetic radiation, wherein the reflector is fully immersed in a multiphase fluid, and a processing subsystem that analyzes the multiphase fluid based upon at least a portion of the reflected portion of the electromagnetic radiation, wherein a principal optical axis of the electromagnetic guiding device substantially aligns with a principal optical axis of the reflector.Type: GrantFiled: July 25, 2013Date of Patent: April 25, 2017Assignee: General Electric CompanyInventors: Sandip Maity, Saroj Kumar Mahalik, Vinayak Tilak, Mason Harvey Guy, Neil Geoffrey Harris, Stuart John Eaton

Patent number: 9103704Abstract: A holding is presented. The holding device includes a male connector comprising a first male extension and a second male extension that extend out of opposite surfaces of a male central disk, an electromagnetic guiding device continuously passing through a central hole that continuously passes through the first male extension, the male central disk and the second male extension, a reflector that is in a direct physical contact with a first end of the electromagnetic guiding device that ends at a top surface of the first male extension, and a holder that covers the first male extension to hold the reflector, and maintain the physical contact between the first end of the electromagnetic guiding device and the reflector.Type: GrantFiled: July 25, 2013Date of Patent: August 11, 2015Assignee: General Electric CompanyInventors: Sandip Maity, Saroj Kumar Mahalik, Vinayak Tilak, Mason Harvey Guy, Neil Geoffrey Harris, Stuart John Eaton

Patent number: 8334786Abstract: Apparatus for the wireless transmission of data, and preferably also of power, across a space between a length of production tubing and a surrounding casing in a petrochemical well, includes a pair of inductively-coupled coils, a first of which is located on the exterior of the production tubing generally coaxially therewith, and the second of which is located on the interior of the casing generally coaxially therewith. This may be used in particular as part of a system for transmitting power and data to/from a sensor monitoring the pressure and/or other environmental conditions within the “B” annulus B of a sub-sea well.Type: GrantFiled: September 24, 2008Date of Patent: December 18, 2012Assignee: Qinetiq LimitedInventors: Adrian Robert Bowles, Stuart John Eaton, Timothy Rupert Charles Jarman, Michael William Hopkins

Patent number: 7715611Abstract: In order to check the authenticity of a banknote or other such document it is printed with two patches of magnetisable ink, and each patch is magnetised to present a multipole sequence of alternating polarity. If the document is folded to bring the two patches together and then rubbed to and fro in the direction of the pole sequences, they will be subject to alternating forces of attraction and repulsion which can be sensed through the fingertips and gives the impression of a physically rippled texture notwithstanding that the patches actually have a smooth surface. The presence or absence of this effect can therefore be used to distinguish between a genuine document bearing such magnetised patches and a counterfeit which may be visually identical but lacks the correct magnetisation. In a variant only one of the patches is printed on the document itself and the other is on a separate “key” device which is rubbed over it to test for the presence of the correct magnetisation.Type: GrantFiled: August 19, 2004Date of Patent: May 11, 2010Assignee: Qinetiq LimitedInventors: Stuart John Eaton, Jonathan Geoffrey Gore, Christopher Robert Lawrence, George Jiri Tomka, Adam Daykin

Publication number: 20080277941Abstract: A device for the generation of electrical power from a fluid flow, and more particularly for harvesting power from flows downhole in oil or gas wells, comprises a cylinder or other blunt body (1) arranged crosswise to the flow and supported on the end of a sprung cantilever arm (3) held in a fixed mount, with freedom to oscillate in response to the shedding of a Karman vortex trail v from the? body. The resultant motion of the body (1) and arm (3) is converted into electrical energy by piezoelectric material (5) which is attached to, and stressed by, flexure of the arm. Other arrangements of piezoelectric and inductive power generation from the oscillation of the device are described.Type: ApplicationFiled: December 19, 2006Publication date: November 13, 2008Applicant: QINETIQ LIMITEDInventors: Adrian Robert Bowles, Stuart John Eaton, Jonathan Geoffrey Gore, Richard Carson McBride, Ahmed Yehia Amin Rahman
