Title: Rotary sleeve to control annular flow
Inventor: NICOLAS ROGOZINSKI
IPC: E21B33/16
Filed: 2015-06-29
Abstract: A wellbore completion system includes a container for delivering plugs or other objects to a wellbore. The container includes a sleeve having a sealing surface at a first end and a geared interface at a second, opposing end. The sealing surface includes voids or apertures that align with or obstruct apertures in a diverter plate, depending on the position of the sleeve, to permit or obstruct annular flow around the sleeve, respectively. A ball valve is coupled to the second, opposing end of the sleeve, and has a valve-geared interface that engages the geared interface of the sleeve. A releasable object, such as a cement wiper plug, may be stored within the conduit of the sleeve. The geared interface relates movement of the ball valve to movement of the sleeve, resulting in simultaneous opening of the valve, closing of the annular flow path, and release of the releasable object.

Title: Pressure and thermal compensation system for subterranean hydraulic control line connectors
Inventor: JOSHUA R JOHNSON
IPC: E21B33/038
Filed: 2016-06-29
Abstract: A wet connection system has pressure compensation operative when running in and thermal effects compensation active in the duration between running in and supporting a bottom hole assembly and hooking up a production string having a mating upper part of the wet connect to the lower part of the wet connect already in the hole. The thermal compensation system is then defeated by locking a floating piston so that applied pressure in a given control line will be used to operate an associated tool connected to that control line. Multiple control lines each similarly compensated are envisioned. The pressure compensation system comes out of the hole with the running tool for the bottom hole assembly.

IPC: G03H1/26
Filed: 2021-07-21
Abstract: A holographic display system 400 comprises a light source 402 (e.g. laser or LED) configured to emit at least partially coherent light, a modulator 404 (e.g. a spatial light modulator/SLM such as a digital micromirror device/DMD, LCD or a Liquid Crystal On Silicon/LCoS device) arranged to be illuminated by the at least partially coherent light and to generate a light field which is a quantised representation of a target light field, H. A spatial filter delimits an aperture 410 in a Fourier plane. The spatial filter may comprise a lens 406 with focal length f and filter 408 defining the aperture 410 wherein the aperture substantially corresponds to a Fourier transform of the target light field, F(H), in the Fourier plane. The filter is arranged such that F(H) substantially does not overlap (i) a Fourier transform of a complex conjugate of the target light field, F(H*), (ii) a Fourier transform of the target light field multiplied by the complex conjugate of the target light field, F(HH*), (iii) a Fourier transform of a square of the target light field, F(H2), or (iv) a Fourier transform of a square of the complex conjugate of the light field F(H*2). The filter ensures that unwanted noise components corresponding to F(H*), F(HH*), F(H2), and F(H*2) are blocked and do not contribute to the displayed holographic image, thus enhancing image quality.
