Publication number: 20190208444Abstract: The solution presented herein manages the feedback from multiple transmission points by reducing the amount of feedback provided by one or more slave nodes to a controlling master node. To that end, methods and apparatus are provided that determine whether there is a need for the slave node to provide feedback to the master node. Responsive to this determination, the methods and/or apparatus operate the master and/or slave node in a reduced feedback mode that manages the feedback provided by the slave node to the master node such that an amount of feedback provided by the slave node when operating in the reduced feedback mode is less than an amount of feedback provided by the slave node when operating in a full feedback mode.Type: ApplicationFiled: June 3, 2016Publication date: July 4, 2019Inventors: Torbjörn WIGREN, Ramon Alejandro DELGADO PULGAR, Katrina LAU, Richard MIDDLETON, Walter MÜLLER, Ying SUN

Publication number: 20190053181Abstract: A multi-point transmission system comprising a plurality of slave nodes (300) for transmitting data to a wireless receiver is described herein. An outer feedback loop and a plurality of inner feedback loops (100) connecting the plurality of slave nodes (300) to a master node (200) controls the timing skew of each slave node (300) using measurements provided by the slave nodes (300) to substantially synchronize the receipt of the transmitted data at the wireless receiver. In so doing, the solution presented herein provides improved multi-point control for any number of transmission points, which improves capacity, and solves the potential flow control problems associated with ultra-lean transmissions.Type: ApplicationFiled: March 22, 2016Publication date: February 14, 2019Inventors: Torbjörn Wigren, Ramon Delgado, Katrina Lau, Richard Middleton

Publication number: 20180054392Abstract: A method for multipoint data flow control, performed in a controller entity of a wireless communication system, comprises receiving of a data flow from a source flow queue. The data flow is split into split data flows, one for each of at least two wireless transmission points. Measures of timing skews for transmissions or quantities from which such timing skews can be deduced are received from each of the at least two transmission points. The data flow splitting is controlled in dependence of the timing skews. The split data flows are transmitted to the at least two wireless transmission points. A method for assisting in multipoint data flow control, network nodes configured for multipoint data flow control and assisting in multipoint data flow control, and computer programs therefore are also disclosed.Type: ApplicationFiled: March 11, 2015Publication date: February 22, 2018Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Torbjörn WIGREN, Linda BRUS, Richard MIDDLETON

Publication number: 20170306385Abstract: The present application relates, in some aspects, to screening methods to identify test compounds that stabilize or destabilize a protein of interest. The present application is based, in some aspects, on the development of a plasmid that can be used to efficiently monitor the stabilities of thousands of proteins after specific perturbations. The plasmid allows for the co-expression of two reporter proteins, each of which is placed under the control of an IRES. In this way both reporters are transcribed together (i.e. are encoded by the same mRNA) and both are translated using an IRES.Type: ApplicationFiled: October 9, 2015Publication date: October 26, 2017Applicant: Dana-Farber Cancer Institute, Inc.Inventors: William G. Kaelin, Gang Lu, Richard Middleton, Kwok-kin Wong

Patent number: 8855316Abstract: The method involves exchange of a quantum signal between a first quantum node and a second quantum node as is usual in known quantum key distribution (QKD) scheme. The first quantum node communicates details of the quantum signal it sent or received with a first remote node. The first remote node thus has all the information to required to take the place of the first quantum node in the key agreement step with the second quantum node. The first quantum node may be arranged to transmit the quantum signal to the second quantum node, in which case the invention provides a distributed quantum transmitter with the control logic in the first remote node being distributed remotely from the actual quantum transmitter in the first quantum node. Communications between the first remote node and first quantum node may comprise or be protected by a quantum key derived by conventional QKD.Type: GrantFiled: January 23, 2009Date of Patent: October 7, 2014Assignee: Qinetiq LimitedInventors: Simon Robert Wiseman, Brian Sinclair Lowans, Richard Middleton Hicks

Patent number: 8681982Abstract: A method of establishing a quantum key for use between a first network node (QNode1) and a second network node (QNode3) in a network for carrying out quantum cryptography includes a key agreement step carried out by a third node (QNode2) and the second node (QNode3) and a subsequent authentication step carried out by the first and second nodes directly. As the key agreement step does not involve QNode1, another key agreement step may be simultaneously performed by another pair of network nodes QNode4, QNode5 to agree a quantum key for use by network nodes QNode1 and QNode5. The invention allows respective quantum keys to be established between a network node and each of a set of other nodes more rapidly than is the case if each quantum key is established serially by key agreement and authentication steps.Type: GrantFiled: December 2, 2009Date of Patent: March 25, 2014Assignee: Qinetiq LimitedInventors: Simon Robert Wiseman, Richard Middleton Hicks, Brian Sinclair Lowans

Patent number: 8151117Abstract: Detection of items stored in a computer system such as computer code, data or information includes obtaining signatures characteristic of programs of interest such as steganographic programs. A signature is obtained by reading code from a program of interest. The code may consist of the first 500 bytes from a .DLL file taken from the programs' core steganographic kernel. This code is then the signature. The computer system compares the signature with files it holds, other than files on a prearranged exclusion list. If a signature is found to match data in a file, the filename, the finding of steganography in it, the file location and the matched signature are recorded by the computer system for output to its user.Type: GrantFiled: October 25, 2004Date of Patent: April 3, 2012Assignee: VocalComm Group, LLCInventor: Richard Middleton Hicks

Publication number: 20070145685Abstract: A game and method for playing same is based on a deck of cards, each card of which uses an icon to represent one element of a transcendental set of elements. Preferably there are three elements in the transcendental set of elements, each one having a value higher than that of one other element of said set and having a value lower than that of the remaining element. Each card also includes a key or transcendental set rule, or portion thereof, so that the players are reminded of which element beats which other element, and an additional statement that relates to the element and provides a fact, tip or recommendation of interest to the player. Several different card games can be played with the deck, including the well-known rock-paper-scissor type of game played traditionally with hand signals, but here with cards.Type: ApplicationFiled: December 1, 2006Publication date: June 28, 2007Inventor: Richard Middleton
