Publication number: 20230021078Abstract: An apparatus and method for operating a ring interconnect are disclosed. The ring interconnect has a plurality of nodes that are used to connect to associated components, and is arranged to transport a plurality of slots around the ring interconnect between the nodes in order to transfer items of traffic allocated into those slots between components connected to the nodes. For each item of traffic, one of the components acts as a source to allocate that item of traffic into a slot, and another components acts as destination to seek to remove that item of traffic from the slot. In a default mode of operation, the ring interconnect is arranged to allow all of the slots to be available for transfer of any items of traffic.Type: ApplicationFiled: July 13, 2021Publication date: January 19, 2023Inventors: Alex James WAUGH, Andrew John Turner, Shobhit Singhal

Patent number: 11448034Abstract: A method and apparatus for removably plugging a wellbore. The wellbore leads to a reservoir having a reservoir temperature. The method includes: selecting a melting point of a metal alloy based on the reservoir temperature; sealing the metal alloy against an interior wall of a tubing, while the tubing is above a ground in which the wellbore is drilled, such that the metal alloy defines a fluid barrier plug against flow of any portion of the reservoir through the tubing when the tubing is disposed within the wellbore; and heating the metal alloy above the melting point while the tubing is disposed within the wellbore such that the metal alloy flows from the tubing and the fluid barrier plug is eliminated.Type: GrantFiled: July 13, 2020Date of Patent: September 20, 2022Assignee: Saudi Arabian Oil CompanyInventors: Robert John Turner, Brett Bouldin

Patent number: 11429426Abstract: An interrupt controller comprises issue circuitry to issue interrupt requests to a processing element and control circuitry to detect presence of a race condition in association with at least one pending interrupt request to be issued, and to set a barrier indicator when the race condition has been resolved. In response to the race condition being present, the issue circuitry is configured to select one of the at least one pending interrupt requests, to issue to the processing element the selected pending interrupt request followed by a dummy request over a path that ensures that the processing element receives the selected pending interrupt request prior to receiving the dummy request. On receiving an acknowledgement indicating that the processing element has received the dummy request, the control circuitry is then configured to set the barrier indicator.Type: GrantFiled: May 1, 2019Date of Patent: August 30, 2022Assignee: Arm LimitedInventors: Timothy Nicholas Hay, Martin Weidmann, Michael Alexander Kennedy, Andrew John Turner

Patent number: 11401549Abstract: A biochemical analysis system analyses polymers by taking measurements of a polymer from a sensor element comprising a nanopore during translocation of the polymer through the nanopore. When a polymer has partially translocated, the series of measurements is analysed using reference data derived from a reference sequence to provide a measure of similarity. Responsive to the measure of similarity, the sensor element may be selectively operated to eject the polymer and thereby make the nanopore available to receive a further polymer. Where the biochemical analysis system comprises an array of sensor elements and is takes measurements from sensor elements selected in a multiplexed manner, responsive to the measure of similarity, the biochemical analysis system ceases taking measurements from the currently selected sensor element and to starts taking measurements from a newly selected sensor element.Type: GrantFiled: May 12, 2020Date of Patent: August 2, 2022Assignee: Oxford Nanopore Technologies PLCInventors: Stuart William Reid, Gavin Harper, Clive Gavin Brown, Daniel John Turner, Andrew John Heron, Christopher James Wright
