Title: Simultaneous source acquisition and separation on general related sampling grids
Inventor: DIRK-JAN VAN MANEN
IPC: G01V1/38
Filed: 2016-05-12
Abstract: Methods are described for separating the unknown contributions of two or more sources from a commonly acquired set of wavefield signals representing a wavefield where the sources traverse general, related activation lines or grids and are synchronously activated while varying at least one parameter between the sources. The parameter may be source signal amplitude, source signal spectrum, source activation time, source location at activation time or source depth. Varying the parameter causes one or more scaled replications of a wavefield with limited cone-shaped support in the frequency-wavenumber domain of at least one of the sources along one or more wavenumber axes or directions. The activation lines or grids are Bravais grids or can be related by affine transformations.

Title: Hybrid power generation system
Inventor: JONATHAN SEBASTIAN HOWES
IPC: F02C6/16
Filed: 2014-08-07
Abstract: A method of operating a hybrid combustion turbine power generation system CTPGS (40, figure 3a) comprising a primary combustion turbine based system (30), and an adiabatic compressed air energy storage ACAES subsystem comprising a compressed air store (50), thermal energy storage TES (41) for removing and returning heat to compressed air when charging and discharging the store. The method comprises the steps of operating CTPGS at least in a power generating first mode wherein CTPGS produces power and the subsystem is not discharging, and a power generating second mode wherein CTPGS produces power and the subsystem is discharging. The method further comprises setting flow valve arrangements 31 (e.g. shut-off or non-return valves) connecting respective spaces leading to compressor 11, ACAES sub-system and combustor 12, preventing flow in the wrong direction through compressor and combustor, whilst allowing flow in or out of TES (41) so as to automatically balance any mismatch in flow between the compressor 11 and the turbine 14, and adjusting compressor flow to modulate the CTPGS power output. The power may be ramped up or down by changing the compressor flow (e.g. declutching 101 the compressor 11 or altering inlet guide vanes) whilst the turbine flow remains unchanged.

Title: Network entities, a wireless communication system and a method for refining a relationship between multiple presence cells
Inventor: JAMES EDWARD BRERETON HARROW
IPC: H04W84/04
Filed: 2016-10-14
Abstract: Each of a plurality of Presence Cells (RTM) are sent a frequency of another Presence Cell (RTM) from a Presence Cell (RTM) list. An access attempt of a wireless communication unit (for instance a UE) is re-directed from a first Presence Cell (RTM) to a selected second Presence Cell (RTM) based on the frequency sent to the first Presence Cell (RTM). Information is obtained from the selected second Presence Cell (RTM) relating to the respective access attempt. A relationship value is formed between the first Presence Cell (RTM) and the selected second Presence Cell (RTM) based on the obtained information and the relationship value in the Presence Cell (RTM) list is refined by obtaining further information from further access attempts of the wireless communication unit to selected Presence Cells (RTM). Refining the relationship value between the Presence Cells (RTM) may mean automatically learning which Presence Cells (RTM) are located close to one another. The re-direct of the wireless communication unit may comprise sending a Radio Resource Control (RRC) Reject to at least one wireless communication unit. Re-direction rules may be used for refining relationships between Presence Cells (RTM).

Filed: 2016-11-17
Abstract: An antenna assembly for a low observable aircraft includes an antenna 6 and a device 20 for changing the field of view 8 of the antenna to a different direction. The device 20 may be wedge shaped and reduce in thickness from a thick end 20a to a thin end 20b. Alternatively, the device may be of uniform thickness and made from a metamaterial (figure 5).

The field of view therefore covers the azimuth plane 14 which is spanned by the roll and pitch axes of an aircraft on which the assembly is located. The upper surface of the device may conform to the shape of the aircraft surface on which it is mounted.

Title: Systems and Methods for Driving Risk Index Estimation
Inventor: OLIVER LEI
IPC: G08G1/16
Filed: 2017-03-10
Abstract: A first vehicle receives vehicle dynamics data and a risk estimation from a nearby second vehicle and uses it, together with its own vehicle dynamics data, to calculate its own risk estimation. A risk reduction action is automatically implemented if the calculated risk estimate is high. If the risk estimate is not high but moderate, then a risk reduction action may instead be recommended using an infotainment head unit such as a dashboard or head up display. The calculated risk estimate may be categorized as either high risk, medium risk or low risk, and corresponding audio or visual indicators may be presented. The vehicle may broadcast its own calculated risk estimate using direct short range communication (DSRC), and may also receive risk estimates and vehicle dynamics data from other vehicles via DSRC. Vehicle dynamics data may be obtained using either sensors or electronic control units (ECU) of that vehicle.

Title: MEMS sensors
Inventor: PAUL WILSON
IPC: H03F3/50
Filed: 2017-03-20
Abstract: An amplifier apparatus 300 for amplifying an input signal from a MEMS capacitive sensor CMEMS includes an antiphase signal generator 304 for generating a second signal VINN which is in antiphase with the input signal VINP received at a sense node 104. An amplifier arrangement 305, which may comprise two single-ended amplifiers 301, 302, receives the input signal and antiphase signal at respective first and second inputs, and outputs corresponding amplified first and second output signals VOUTP, VOUTN. The antiphase signal may be generated by an inverting amplifier (Fig.2, 201), or by a feedback amplifier 304 receiving a signal indicative of a common-mode voltage of the output signals and a common-mode reference voltage VCMREF. Alternative amplifier arrangements include modulation of a bias voltage VBIAS applied to the MEMS capacitive sensor based on the antiphase signal. Deriving an antiphase signal to the received input signal, and using an amplifier arrangement with differential inputs and outputs, provides for good linearity and noise performance over a large operating range. Applications include portable battery powered devices such as a mobile phone with a MEMS microphone.
