Title: Audio processing
Inventor: JELLE VAN MOURIK
IPC: H04S3/00
Filed: 2016-12-23
Abstract: Apparatus and method for generating candidate audio propagation directions 260-266 from a sound source position in a virtual environment. This is followed by modelling audio propagation properties of a current candidate direction and detect whether an audio propagation path originating in the current candidate direction from the sound source arrives at the listening position 200. This is then followed by selecting a predetermined number of candidate directions for which an audio propagation path arrives at the listening position and combining the audio propagation properties of the selected candidate directions. Preferably there is a filter to apply the audio filtering parameters to an audio signal. Preferably the candidate paths selected are selected in order of those which are first generated. Preferably the order of path generation is random. Preferably the position of a listener is detected and mapped.

Title: Establishing crytographic identity for an electronic device
Inventor: JAN-ERIK GUSTAV EKBERG
IPC: G06F21/62
Filed: 2017-01-03
Abstract: This application is for a way of establishing the cryptographic identity of a device that may have many different manufacturers for each of the different components of the device, called stakeholders. The method may involve having the first stakeholder generate two transfer tokens S3 and using a hash to verify his identity S4. He then may hash the two transfer token and use these three pieces of data to form the first block in the chain S8. This is then uploaded to a public ledger and the second of the two transfer tokens may be returned to the first stakeholder who configures the device with the keys needed to establish a cryptographic identity S11. The second transfer token may then be sent to the next stakeholder S13 who uses it to prove his identity and take ownership of the device. This process is then repeated for each stakeholder in the chain. The public ledger is then used to track the cryptographic identities of the stakeholders, as well as the order in which they are uploaded in the chain.

Title: Heating element and method of analysing
Inventor: Howard Rothwell
IPC: A24F40/46
Filed: 2017-02-01
Abstract: A method for obtaining a heating element 10a, e.g. a mesh of sintered stainless steel fibres, for an electronic vapour provision system. The method comprises providing a sheet of electrically conductive porous material 10a. Amounts of light I1, I2 transmitted through at least two locations on the sheet are measured to obtain a set of optical transmission values. These values include a maximum and minimum. A difference value is calculated from them and is compared with a predetermined acceptable variation in optical transmission. The sheet is selected for use as a heating element if the difference value falls within the acceptable variation. This ensures that the sheet 10a will produce uniform heating in use. The acceptable variation can be determined using a known relation between optical transmission and electrical resistance for the porous material 10a.

Title: Adaptive equalisation
Inventor: SUMANTH EADALA
IPC: H04L27/38
Filed: 2017-02-02
Abstract: A receiver has a first equalising filter connected in series with a second equalising filter. The first equaliser receives a first signal in a first modulation mode and adaptively updates its coefficients to reduce the error signal between the expected and determined signal until the error signal reaches a threshold. The first equalizers coefficients are locked when a second signal in a second modulation mode is received, the second signal being filter by the first equaliser with locked coefficients and then the second adaptive equaliser. The second equalizers coefficients are continuously updated to reduce a second error signal. The received signals are a sequence of symbols encoded by inphase and quadrature components, and the first signal in an initial modulation mode such as QPSK may be encoded at a lower bitrate than the second signal in a subsequent modulation mode such as 16 QAM. The expected signal may be determined using an LMS algorithm. The QAM demodulator may be used in a downhole telemetry module in a wellbore to communicate with a surface controlling module.

Title: Ion detection
Inventor: ALEXANDER KHOLOMEEV
IPC: H01J49/42
Filed: 2011-05-12
Abstract: An electrostatic ion trapping device with detection electrodes 80, 85 to detect image current signals from trapped ions. A controller applies a voltage to a shielding conductor 140, between two detection electrodes 80, 85, based on a detected image current. This reduces the capacitance between detection electrodes 80, 85 and/or compensates oscillation frequency changes caused by space charge effects. A trapping field generator may comprise outer electrodes concentric with an inner electrode 90, which may be the detection electrodes. The shield conductor 140 may comprise a ring concentric with the inner electrode 90. The controller may phase modulate the voltage applied to the shielding conductor 140 to cancel image charge effects. The ion trap may be used in an electrostatic orbital trapping mass analyser or a Fourier-Transform ion cyclotron resonance analyzer, in which ions form packets that oscillate with a period. A preamplifier may provide an output based on image currents, and capacitance between compensatory and signal-carrying parts affects the signal-to-noise ratio of the preamplifier.

Title: Reduced bandwidth handshake communication
Inventor: YONGBEOM PAK
IPC: H04W12/06
Filed: 2017-04-13
Abstract: Broadly speaking, embodiments of the present technique provide methods, apparatuses and systems for performing a TLS/DTLS handshake process between machines in a manner that reduces the amount of data sent during the handshake process. A digital certificate may be provisioned on a client device 102 by a bootstrapping server. The client device may be an internet of things IOT type device which may have limited capacity. In order to establish communication between a server 104 and the client 102 the client and server must validate each other, instead of exchanging digital certificates in a conventional manner, the client transmits a URL to the server allowing the server to retrieve the certificate Cert(S) without requiring the client to transmit the certificate. Likewise, a fingerprint of the certificate may be sent from the server to the client rather than a full certificate. The certificate may contain a client device identifier, a server identifier and a further identifier identifying the relationship between client and server.

Filed: 2017-07-11
Abstract: A method of fault monitoring in a utility supply network containing parent nodes and child nodes dependent upon parent nodes comprises counting the total number of received failure indications from all child nodes of a parent node. If the total exceeds a threshold, then a count is made of the number of child nodes having failure indications attributed to them exceeding a limit for that child node. If the count exceeds a second threshold then it is determined that the parent is likely impaired. The network may be a mobile communications network in which the child nodes are base stations and the parent nodes are controllers for a group of base stations or part of the network backhaul. The failure indications may be alarms at the child node or queries from users about unsatisfactory network performance.

Abstract: A minimum non-reduction association rule mining method based on an item subset example tree. The method comprises the following steps: generating an item subset in an example item database by using a closed itemset generated from a single item and a union operation of a set, the set being a proper subset of a power set of an itemset; constructing an item subset example tree structure of the example item database by using the generated item subset; mining a closed frequent itemset and a minimum generation element thereof in the item subset example tree and rapidly generating a minimum non-reduction association rule according to the mined closed frequent itemset and the minimum generation element thereof. By using the closed itemset generated from a single item, a plurality of item subsets can be obtained, the item subset example tree can be constructed, and hierarchical relationships between the item subsets and corresponding support levels thereof can be described, thus effectively reducing the number of retrievals between examples and items. The storage space is also effectively reduced at the same time, thereby increasing the speed and efficiency of mining the minimum non-reduction association rule.
