Patent number: 11002878Abstract: A sensing element (10) for an intrinsic gravity gradiometer (IGG) for use in sensing variation in a gravity field at a location. The sensing element (10) is flexible, elongate and has unfixed opposed ends (12, 14) when part of the gravity gradiometer. The sensing element can be a metallic ribbon, and can be mounted by a number e.g. 3 or 5, pivot points or axes 30-40 at each of the opposed sides along the sensing element, with the opposed ends of the sensing element free to move. The pivot points or axes can include pins, preferably cylindrical pins (48) or the sensing element may be etched within the side wall and remain joined to the remainder of the side wall by connections. The sensing element (10) can form part of one or more resonant cavities or wave guide (44, 52-66), such as a side or dividing wall (46) or part thereof. A dual phase bridge (61,612) arrangement can be provided. Electrical current (I) can be injected into the sensing element.Type: GrantFiled: October 23, 2017Date of Patent: May 11, 2021Assignees: The University of Western AustraliaInventors: Alexey Vladimirovich Veryaskin, Jeremy Francis Bourhill, Eugene Nikolay Ivanov, Michael Edmund Tobar

Patent number: 5990767Abstract: A method of producing a microwave resonator comprising a cavity (50) defined, at least in part, by a generally cylindrical wall (64) having an electrically conductive inner surface and containing a generally cylindrical piece of low loss dielectric material (22), characterised by forming a generally cylindrical piece of low loss dielectric material of predetermined size and placing same in a cavity to produce a microwave resonator which operates in a particular mode at a specific frequency at a particular temperature. Microwave radiation corresponding to a further operating mode is then passed into the cavity and then the frequency corresponding to the further operating mode is searched for and measured. A further generally cylindrical piece of dielectric material is produced by scaling from the first piece of dielectric material according to the ratio between the first and second frequencies.Type: GrantFiled: November 21, 1997Date of Patent: November 23, 1999Assignees: Poseidon Scientific Instruments Pty Ltd, University of Western AustraliaInventors: Eugene Nikolay Ivanov, David Gerald Blair, Michael Edmund Tobar, Jesse Hyuck Searls, Simon John Edwards
