Patent number: 11768179Abstract: Embodiments of the invention provide a “tool-kit” of processing techniques which can be employed in different combinations depending on the circumstances. For example, flow speed can be found using eddy tracking techniques, or by using speed of sound measurements. Moreover, composition can be found by using speed of sound measurements and also by looking for turning points in the k-w curves, particularly in stratified multi-phase flows. Different combinations of the embodiments can therefore be put together to provide further embodiments, to meet particular flow sensing requirements, both on the surface and downhole. Once the flow speed is known, then at least in the case of a single phase flow, the flow speed can be multiplied by the interior cross-sectional area of the pipe to obtain the flow rate. The mass flow rate can then be obtained if the density of the fluid is known, once the composition has been determined.Type: GrantFiled: November 23, 2020Date of Patent: September 26, 2023Assignees: Silixa Ltd, Chevron U.S.A.

An operations control center (OCC) receives helium concentration levels in the tube and instructs a controller in the tube to release helium into the tube when detected levels of helium is lower than the desired level of helium. Another implementation is described where a capsule traversing the tube may have a source of helium gas that can be released into the tube. A hybrid approach is also described where helium can be released from a source within the tube and from another source within the capsule.Type: GrantFiled: May 13, 2019Date of Patent: January 25, 2022Assignee: Hyperloop Transportation Technologies, Inc.Inventors: Alexandre Neophytou, Michael Sarin, Alexandre Zisa, Spencer John Baldwin

Patent number: 11169657Abstract: The systems and methods described herein are directed to resource monitoring and resource consumption analytics. Resource usage is tracked through a gateway device monitoring resources using remote input sensors, and usage data is transmitted to a central processing unit whereby the data is interpreted and compared with usage over time and site conditions such as weather. For example, incoming usage data is compared with resource signatures in a signature library representing an ideal usage or historical usage for given site condition. This data is interpreted into simple command displays with alerts, alarms, thereby reporting and alerting to an end-user via multiple delivery mechanisms, of potential sources of resource waste or loss. Further, the alerts or alarms can include easily interpreted recommendations to allow a non-skilled worker to take corrective procedures to maximize efficient use of the consumable resources.Type: GrantFiled: August 28, 2019Date of Patent: November 9, 2021Assignee: APANA Inc.Inventors: Matthew W.

Patent number: 11002111Abstract: The disclosure describes hydrocarbon flowline corrosion inhibitor overpressure protection. Such a protection system includes a fluid flow pathway fluidically coupled to a corrosion inhibitor injection pump that injections corrosion inhibitor into a hydrocarbon carrying flowline. When the injection pump pressure exceeds a threshold flow pressure, the corrosion inhibitor is flowed through a first branch of the fluid flow pathway to relieve the excess pressure. The first branch is fluidically isolated from a second branch. When a rupture disc in the first branch fails, then the corrosion inhibitor is diverted to flow through the second branch and the first branch is isolated from the corrosion inhibitor flow.Type: GrantFiled: December 19, 2018Date of Patent: May 11, 2021Assignee: Saudi Arabian Oil CompanyInventors: Fathi BuGubaia, Khalid Al Ghamdi, Mohammad R.

Patent number: 10969431Abstract: A semiconductor package comprises a controlled voltage domain (CVD) and a master voltage domain (MVD). The MVD comprises an error-tolerance control (ETC) circuit. A basic execution block in the CVD generates a basic output value, based on at least two input values. A test execution block in the CVD generates a test digital root, based on digital roots of the input values. A digital root comparator in the CVD determines whether a digital root of the basic output value matches the test digital root. An error reporter in the CVD sends an error report to the ETC circuit in response to a determination that the digital roots do not match. The ETC may automatically adjust at least one power characteristic of the CVD, based on the error report. Other embodiments are described and claimed.Type: GrantFiled: December 23, 2019Date of Patent: April 6, 2021Assignee: Intel CorporationInventors: Richard William Dorrance, Andrey Vladimirovich Belogolovy, Xue Zhang, Hechen Wang
