Title: Welded Component and method of fabrication
Inventor: CARTHY MARK
IPC: E02F3/38
Filed: 2013-09-10
Abstract: A box-section arm (16, fig 1) of an excavator or the like has a pivot axis (19, fig 1) at one side. Two flat plates 25, 26 close the underside of the box-section adjacent the pivot axis and are welded transversely from a pair of projections 28, 29 at one side, to corresponding pair of projections 28, 29 at the other side. The projections 28, 29 are partially but not wholly removed (eg by grinding) after welding to leave the welded joint substantially flush with the longitudinal edge of the plates. These extensions ensure that over the length of the weld the joint is of consistent quality and avoids stress which may result in failure of the weld.

Title: Frequency stabilization of an atomic clock against variations of the C-field
Inventor: MARMET LOUIS
IPC: G04F5/16
Filed: 2012-02-06
Abstract: The frequency of an atomic clock may be stabilized against C-field variation by applying a rf magnetic field perpendicular to the C-field to cause a coherent population transfer between Zeeman states that compensates for quadratic frequency shift of transitions of the clock. The cancellation, provided by a feed-forward mechanism, is exact. The invention can be implemented in any atomic clock by including an electrode in the clock generating a magnetic field perpendicular to the C-field, and providing an electronic circuit to send rf signals to the electrode.

Title: Method for assisting the driver of a motor vehicle in a collision avoidance manoeuvre
Inventor: KIEREN MARTIN
IPC: B60W30/095
Filed: 2014-02-24
Abstract: The invention relates to a method and apparatus for assisting the driver of a motor vehicle in a collision avoidance manoeuvre. The danger of an imminent or impending collision of the motor vehicle is detected by means of an environment sensor system. An environment modelling takes place and, on the basis of the environment modelling, a collision avoidance trajectory for the motor vehicle is determined. A quality measure representing the quality of the environment modelling is determined and an assistance of the driver for guiding the vehicle on the collision avoidance trajectory by means of driver-independent steering and/or braking interventions takes place. The maximum intensity of the steering and/or braking interventions is dependent on the determined quality measure.

Title: Data processing apparatus and method for processing vector operands
Inventor: BOETTCHER MATTHIAS LOTHAR
IPC: G06F17/16
Filed: 2014-03-07
Abstract: Disclosed is a data processing apparatus 2 with processing circuitry 4 for processing vector operands from a vector register store 6 in response to vector micro-operations. The micro-operations have control information identifying which data elements of a portion of the vector operands are selected for processing. Control circuitry 20 detects whether the control information of a micro-operation satisfies a predetermined condition indicating that the portion of the vector does not contain any selected elements. If the condition is not satisfied the vector is processed by the micro-operation, otherwise the micro-operation is replaced with a lower latency operation. The portion of the vector may be the whole vector. The replacement operation may be a no-op, setting the destination register to the same as the source register, or setting the destination to a set value. The control information may be mask information, vector length information or vector format information.

Title: Read-detection in solid-state storage devices
Inventor: MITTELHOLZER THOMAS
IPC: G11C11/56
Filed: 2012-06-27
Abstract: Methods and apparatus are provided for detecting N-symbol codewords stored in multilevel-cell solid-state memory. Each codeword is a permutation of an N-symbol vector of a predefined set of N-symbol vectors. The symbols of each codeword, each of which has one of q symbol values, are stored in respective q-level cells of solid state memory (2), where Nâ‰¥q>2. The memory cells storing a group of codewords are read to obtain respective read signals each comprising N signal components corresponding to respective symbols of a codeword. The components of each read signal are ordered according to signal level to produce an ordered read signal. Corresponding components of the ordered read signals are averaged to produce an average read signal. A reference signal level corresponding to each of the q levels of the memory cells is determined in dependence on the average read signal and predefined probabilities of occurrence of each symbol value at each symbol position in a said codeword whose symbols are ordered according to symbol value. The codeword corresponding to each read signal is then detected in dependence on the reference signal levels.

IPC: F25D29/00
Filed: 2015-09-25
Abstract: A refrigeration apparatus 3 comprises a liquefied gas storage device 6 having a headspace 29 containing gas, a first conduit 34 communicates the gas between the headspace of the storage device and a heat exchanger 10, and a second conduit 12 communicates the gas from the heat exchanger to an exhaust vent 14 into the atmosphere.

The heat exchanger may be disposed in a compartment 4 of a vehicle (truck 2) and air blown by a fan is passed over the heat exchanger to effect cooling of the compartment to a desired temperature by detecting temperature using a sensor 20. The exhaust may comprise a muffler / silencer to reduce noise caused by venting gas. Passing the vented gas from the storage device through the heat exchanger pre-cools the compartment and the gas is heated so that the vented gas does not damage / freeze the floor upon which it is vented.

Title: Network security
Inventor: ANDREW J THOMAS
IPC: H04L29/06
Filed: 2016-06-20
Abstract: A gateway or other network device may be configured to monitor endpoint behaviour, and to request a verification of user presence at the endpoint under certain conditions suggesting, e.g., malware or other endpoint compromise. When a network request is directed to a low-reputation or unknown network address, user presence may be verified to ensure that this action was initiated by a human user rather than automatically by malware or the like. User verification may be implicit, based on local behaviour such as keyboard or mouse activity, whether a user is logged in, or a display is locked; or the user verification may be explicit, such as where a notification is presented on a display of the endpoint requesting user confirmation to proceed. Evaluating the status of the endpoint may include examining a secure heartbeat from the endpoint. Also disclosed is the feature of monitoring a status of the endpoint, periodically creating a status indicator characterising the status, generating a user presence indicator containing an indication of whether a human user is present at the endpoint, creating (and transmitting to a gateway) a heartbeat containing the status indicator and the user presence indicator. The network device may include a firewall.

IPC: G06N3/063
Filed: 2016-07-07
Abstract: An artificial neural network (ANN) comprises a cross-point array 60. At each neural node 20 there is a plurality of programmable non-volatile memory elements 62a, 62b to store weights associated with the node. Each element is switchable between first and second impedance states such that the plurality of elements digitally encodes a range of impedance values. Compared to analogue filamentary resistive memory elements, the present all digital cross point array does not need to be trained in situ. This allows devices in the Internet-of-Things (IoT) comprising the ANN to take advantage of cloud-based training. The plurality of elements may be arranged in parallel within crosspoint array modules encoding a linear scale of conductance values and may comprise using sneak paths through memory elements in series to digitally-encode impedance values. The elements may comprise: correlated electron RAM (CeRAM), mamristors, resistive RAM (ReRAM), phase-change memory (PCM), or spin-torque magnetic RAM (STT-MRAM).
