Title: Graphics processing
Inventor: JØRN NYSTAD
IPC: G06T17/20
Filed: 2015-08-03
Abstract: A graphics processing pipeline comprises a tessellation stage 110 that tessellates a patch (116,118 &122 in figs. 6-8) into tessellation primitives. Tessellation vertex coordinate pairs are generated defining within a parameter space the locations of vertices of the tessellation primitives for the patch. The coordinate pairs are initially represented using a first binary representation and are then encoded into a more convenient (e.g. shorter) second binary representation, but without any loss of resolution in the data. Encoding comprises mapping (e.g. using an accumulator) at least one initial coordinate pair to a mapped coordinate pair represented using the second binary representation, wherein the mapped coordinate pair may define a location within an area (124,125 in fig. 9) of parameter space that would otherwise be unused, invalid and/or unreachable for vertices of the tessellation primitives for the patch. A position for the vertex of the tessellation primitive may be generated from the mapped coordinate pair, comprising decoding the mapped coordinate pair represented by the second binary representation back into the tessellation vertex coordinate pair represented by the first binary representation, and generating a position for the vertex of the tessellation primitive from the tessellation vertex coordinate pair.

Title: Session attribute propagation through secure database server tiers
Inventor: RODNIANSKY LEONID
IPC: H04L29/06
Filed: 2014-02-24
Abstract: Mechanisms are provided for handling a database client request. An encrypted database client request (DCR) is received, by an unsecure access local agent, from a client computing device as part of a session between the client computing device and a database data processing system. The unsecure access local agent retrieves a database session information (DSI) address corresponding to the session and generates a first unique identifiable key (UIK) based on a portion of the encrypted DCR. The unsecure access local agent generates a DSI mapping data structure that maps the first UIK to the DSI address. A secure access local agent of the database data processing system processes the encrypted DCR using the DSI mapping data structure.

IPC: H02N2/04
Filed: 2014-03-12
Abstract: A compact, easily manufactured, axisymmetric mechanism can be configured to change the magnitude of a short-movement linear motion, or also reverse the movement direction, of an actuator for control of movable elements. The mechanism is bidirectional and reversible, functioning symmetrically, and does not contain any gears nor lead screw threads.

Title: Enhanced management of ACs in multi-user EDCA transmission mode in wireless networks
Inventor: Stéphane Baron
IPC: H04W74/08
Filed: 2016-10-21
Abstract: To avoid blocking node Access Category (AC) queues in the Multi-User Enhanced Distributed Channel Access (MU EDCA) mode due to regular OFDMA transmission of data from another AC queue in resource units provided by an Access Point (AP), a dedicated timer is used for each AC queue, in order for them to be able to exit the MU EDCA mode independently of the other AC queues. In this respect, upon successfully transmitting data stored in two or more traffic queues, in each of one or more accessed resource units provided by the AP, the node sets each traffic queue transmitting in the accessed resource unit in the MU EDCA mode for a predetermined duration counted down by a respective timer associated with the transmitting traffic queue. Next, upon expiry of any timer, the node switches back the associated traffic queue to the conventional EDCA mode.

Title: Submersible pump monitoring
Inventor: ANDREW CLARKE
IPC: G01H9/00
Filed: 2015-03-02
Abstract: Monitoring the operation of an in-well electrical submersible pump (ESP) 2 using an optical fibre distributed acoustic sensor (DAS) to measure one or more operation frequencies of the ESP. Rates of change of the operating frequency are measured at the same time as relative or absolute changes in operating frequency and alert thresholds are set for both rates of change and changes in operating frequency to sound an operator alert. Any change in the operating frequency may be detected during start-up or steady state operation of the ESP. The operator may be alerted if there is an abrupt change in operation frequency or if the operation frequency drifts outside of a predetermined range. A plurality of operating frequencies may be measured and the spectrum of the ESP may be determined and monitored using a Fourier transform, as well as determining a fundamental higher order harmonic operation frequencies.
