Title: Compiling an application program written in legacy source code according to stack or legacy semantics based on equivalence
Inventor: WRIGHT JEREMY
IPC: G06F9/45
Filed: 2013-08-14
Abstract: A computer system (1200) prepares an application program (1210) comprising legacy source code written in, for example, COBOL for deployment into a processing environment (1260). The system has a control flow analyser unit (1242) operable to determine equivalence in control flow between source code if compiled using stack semantics and if compiled legacy semantics. Determination of equivalence involves generating and inspecting a directed call graph to identify strongly connected components. In the absence of such, tuples comprising ranges of functions, end points of functions and reaching endpoints of direct/indirect predecessor nodes are created and a union of the range and the reaching end point calculated. If the union is NULL and there are no strongly connected components then equivalence exists. The system has a compiler unit (1243) to compile the legacy source code using stack based semantics if equivalence is determined and using legacy semantics if non-equivalence is determined. This compilation may be to intermediate code such as Java Bytecode or common intermediate language (CIL) code.

Title: Dynamic multicast state aggregation in transport networks
Inventor: KEESARA SRIKANTH
IPC: H04L12/46
Filed: 2013-12-19
Abstract: An ingress sender node ING and a set of egress receiver nodes EGR-1, EGR-2, EGR-3, EGR-4 for each of a plurality of multicast streams within a network, e.g. a Shortest Path Bridging (SPB) network, are identified and assigned a unique address. The same unique address, e.g. a Multicast Encapsulation Address or a Backbone Media Access Control (BMAC) address, is used in the forwarding table within the core of the network for any set of multicast streams that traverse the network from the same ingress sender node ING to the same set of egress receiver nodes EGR-1, EGR-2, EGR-3, EGR-4. A multicast tree may be built routed at the ingress node ING and leading to each of the egress nodes EGR-1, EGR-2, EGR-3, EGR-4 in a list following shortest path rules. Hence, the size of the multicast forwarding table in the core of the network may be reduced to be less than the number of access multicast flows in the network.

Title: Estimation of direct arrival signals based on predicted direct arrival signals and measurements
Inventor: HEGNA STIAN
IPC: G01V1/38
Filed: 2015-02-12
Abstract: Estimation of direct arrival signals includes obtaining 646 notional source signatures for notional sources that correspond to source elements in a seismic source. A first predicted direct arrival signal at a first location and a second predicted direct arrival signal at a second location is determined 647. The first location corresponds to a seismic receiver and the second location does not correspond to a seismic receiver. A transfer function is determined 648 based on the first predicted direct arrival signal at the first location and the second predicted direct arrival signal at the second location. An estimated direct arrival signal at the second location is determined 649 based on the transfer function and a measurement by the seismic receiver corresponding to the first location. The estimated direct arrival signal represents what a measured direct arrival signal would be at the second location. In another aspect, the first direct arrival signal is predicted based on a propagation of a combined notional source signature to a first location having a receiver taking into account a distance from the source elements of the combined source to the receiver.

Title: Memory access by dual processor systems
Inventor: ABHIJEET SINGH
IPC: G06F13/24
Filed: 2015-06-08
Abstract: A Global Navigation Satellite System (GNSS) receiver comprises a dual processor with a tracker and a control processor utilising a common flash memory. A method to avoid access conflicts comprises: generating or receiving data for storage at the control processor (20); disabling operations of the tracking processor (22) and the interrupts of the control processor; storing the data by the control processor (25). After the data are stored, the interrupts of the control processor are enabled and so is the tracking processor. At this stage the time period the tracking processor has been disabled is ascertained (27) and the processor reset (28) if the period is greater than a threshold. Parallel flash and SQIF can have different thresholds. Performing the method may depend on checking (21) whether the receiver is stable, e.g. by counting consecutive valid position outputs. Instruction fetches are coordinated with data storage without degrading GNSS receiver performance.

Title: Optical couplers used in a downhole splitter assembly
Inventor: LAGACE MICHAEL
IPC: G02B6/44
Filed: 2014-05-16
Abstract: Techniques and apparatus are provided for downhole sensing using optical couplers in a downhole splitter assembly to split interrogating light signals into multiple optical sensing branches (608, 610, 622, 624, 626). Each optical branch may then be coupled to an optical sensor (e.g., a pass-through or an optical single-ended transducer (OSET) 612, 626, 628) or to another optical coupler for additional branching. The sensors may be pressure/temperature (P/T) type transducers. Some systems may exclusively use OSETs as the optical sensors. In this manner, if one of the OSETs is damaged, it does not affect light traveling to any of the other sensors, and sensing information from remaining sensors is still returned.

Title: Current-limiting droop controller for power converters
Inventor: QINGCHANG ZHONG
IPC: H02M7/48
Filed: 2015-12-10
Abstract: A controller for a grid-tied inverter provides ancillary services to the grid while limiting the current under both normal and abnormal grid conditions. It involves the measurement of the inverter output voltage, the grid voltage and the inverter current in order to calculate the real, reactive power and RMS output voltage, but does not require the knowledge of the system parameters. The controller generates an output consisting of a feed-forwarded voltage term, a controllable voltage source and a virtual resistance term multiplied with the inverter current. The virtual resistance is controlled to stay within a given range having a positive lower bound and the controllable voltage source is generated according to the droop function. As a result, the inverter current remains below a given value at all times, even during transients, independently from grid variations or faults (short circuit or voltage sag). The invention introduces a controller with a continuous-time structure and does not require any switches, additional limiters or monitoring devices to achieve the current-limiting property.

Title: Generating a plurality of one time tokens
Inventor: ROBERT BOOTHBY
IPC: H04L9/32
Filed: 2016-06-30
Abstract: Generating a plurality of different one time tokens (OTT) by acquiring a first numerical value from a predetermined sequence of consecutive numerical values, applying format preserving encryption to the acquired first numerical value to generate a first numerical one time token. Then a second numerical value is acquired from the predetermined sequence of consecutive numerical values, the acquired second numerical value being different to the acquired first numerical value and applying the format preserving encryption to the acquired second numerical value to generate a second numerical one time token. The format preserving encryption applied to both values may use the same secret key. The sequence of numbers may be split into subsets with each subset having a secret key which is identified by a numerical character at a predetermined character position within the numerical value acquired from the predetermined subset. Alternatively the predetermined character position may not be present in the numerical value acquired from the predetermined subset. The above is particularly concerned with generating OTTs for transmission (e.g. to an email address or a mobile telephone).
