Patent number: 12131155Abstract: An apparatus and method are provided for speculatively vectorising program code. The apparatus includes processing circuitry for executing program code, the program code including an identified code region comprising at least a plurality of speculative vector memory access instructions. Execution of each speculative vector memory access instruction is employed to perform speculative vectorisation of a series of scalar memory access operations using a plurality of lanes of processing. Tracking storage is used to maintain, for each speculative vector memory access instruction, tracking information providing an indication of a memory address being accessed within each lane. Checking circuitry then references the tracking information during execution of the identified code region by the processing circuitry, in order to detect any inter lane memory hazard resulting from the execution of the plurality of speculative vector memory access instructions.Type: GrantFiled: March 25, 2020Date of Patent: October 29, 2024Assignees: Arm Limited, The Chancellor, Masters and Scholars of the University of CambridgeInventors: Peng Sun, Timothy Martin Jones, Giacomo Gabrielli

Patent number: 11874459Abstract: The disclosure provides a display device for head mounting, in particular a Maxwellian display device, with an enlarged eye-box. The display device includes a light source emitting light beams for forming an image, an optical system for guiding the light beams to a beam forming element. The beam forming element is configured to converge each of multiple sets of the light beams into a different point of convergence, for example on an exit pupil of the display device. Each point of convergence is a convergent viewing point for a user. The eye-box is thus enlarged.Type: GrantFiled: September 24, 2020Date of Patent: January 16, 2024Assignees: Huawei Technologies Co., Ltd., The Chancellor, Masters and Scholars of The University of CambridgeInventors: Tao Lin, Qing Zhang, Jia Jia, Pawan Shrestha, Matt Pryn, Daping Chu

Patent number: 10730862Abstract: The present invention relates to bifunctional compounds, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins that are degraded and/or otherwise inhibited by bifunctional compounds of the present invention. In particular, the present invention is directed to compounds, which contain on one end a VHL ligand that binds to the ubiquitin ligase and on the other end a moiety that binds a target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. The present invention exhibits a broad range of pharmacological activities associated with compounds of the present invention, consistent with the degradation/inhibition of targeted polypeptides.Type: GrantFiled: January 11, 2013Date of Patent: August 4, 2020Assignees: Yale University, Glaxosmithkline Intellectual Property Development, Cambridge Enterprise Limited University of CambridgeInventors: Craig M.

Patent number: 9752970Abstract: A method of testing the oxidation resistance of an alloy includes applying a layer of salt on the alloy's surface and placing the alloy in a furnace at a temperature of at least 1000° C. and containing an oxygen containing gas. The alloy is maintained in the furnace at the predetermined temperature for a period of time then the alloy is removed from the furnace and the alloy is to cool to ambient temperature or other suitable temperature. These steps are repeated for a number of times to maintain the salt on the alloy's surface at a level of 0.5 to 30 ?g cm?2 h?1. The alloy is weighed periodically to determine oxidation resistance. The addition of salt reduces the time to test the oxidation resistance of the alloy and the addition of the salt mimics the degradation of the alloy in a real working environment in a gas turbine engine.Type: GrantFiled: April 20, 2015Date of Patent: September 5, 2017Assignees: ROLLS-ROYCE PLC, THE CHANCELLOR, MASTERS AND SCHOLARS OF THE UNIVERSITY OF CAMBRIDGEInventors: Stephen Moray Bagnall, Julian Charles Mason-Flucke, Catherine Mary Fiona Rae, Siavash Pahlavanyali

Patent number: 9679256Abstract: Embodiments herein provide automated assessment of examination scripts, such as English for Speakers of Other Languages (ESOL) examination scripts, written in response to prompts eliciting free text answers. In an embodiment, the task may be defined as discriminative preference ranking. Further, a system employing such methodology may be trained and tested on a corpus of manually-graded scripts. Embodiments herein, unlike extant solutions, are relatively prompt-insensitive and resistant to subversion, even if the operating principles are known. Embodiments may also detect scripts which are linguistically good but non-responsive to prompts such as memorized responses.Type: GrantFiled: October 6, 2010Date of Patent: June 13, 2017Assignee: THE CHANCELLOR, MASTERS AND SCHOLARS OF THE UNIVERSITY OF CAMBRIDGEInventors: Ted Briscoe, Ben Medlock, Oeistein Andersen
