Title: Partial Scan Cell
Inventor: MCLAURIN TERESA LOUISE
IPC: G01R31/3185
Filed: 2013-11-21
Abstract: An integrated circuit has a scan chain with serial scan cells 32, 34 and a partial scan cell 36. The partial scan cell is arranged such that, during a scan mode in which serial data is being shifted into and out of the serial scan cells, a fixed value is captured and stored into the partial scan cell. This avoids the presence of unknown data values within the signal paths between the functional logic 38, 40 being tested. To store a fixed value in scan mode, the input D of the partial scan cell is connected to a logic circuit 42 such as a NAND or NOR gate. A scan enable signal SE provides one input of the NAND gate; the output of functional logic 38 provides the other. During scan mode, the scan enable signal is asserted and the output of the NAND gate is forced high, producing a fixed value at the partial scan cell input. In functional mode, the scan enable signal is not asserted, and the input of the partial scan cell depends on the output of functional logic.

IPC: G05B23/02
Filed: 2013-12-17
Abstract: A configuration of sensors within an asset (for example an industrial process such as chemical refineries, wafer manufacturing and mining), for monitor physical operating parameters of the asset. A server arrangement is operable to receive the sensor signals in real time 304. Software products are operable to analyse the sensor data 306 for determining an aggregate efficiency of operation of the asset based upon a weighted combination of contributions from one or more apparatus of the asset. The weightings may be determined based on historical data, artificial intelligence or neural networks. The sensors may be connected wirelessly to the server. The system may further detect apparatus failures and determine maintenance schedules. Simulation models 308 are used to identify recommended adjustments for improving the efficiency of operation of the asset.

IPC: F02C6/18
Filed: 2014-03-28
Abstract: A combined cycle gas turbine plant 100 has a gas turbine 104 and a steam turbine 106 mounted on the same shaft 105. A control system 122 is configured for switching the plant from a rated mode of operation, in which the plant is operated on gas turbine output and steam turbine output, to a reduced load mode of operation, in which the plant is operated on gas turbine output alone.

Title: Unit pump for use in a combustion engine
Inventor: DANIELE CARBONI
IPC: F02M59/48
Filed: 2015-01-22
Abstract: A unit pump 10 for a combustion engine, in particular a vehicular Diesel engine, is mounted in a cylinder 26 of the engine, eg in the unused fourth cylinder of a downsized four-cylinder engine of which only three cylinders are used for combustion.

Title: Power supply switcher control
Inventor: GERARD WIMPENNY
IPC: H03F3/217
Filed: 2015-05-28
Abstract: An envelope-tracking power supply 4 for an RF power amplifier 2 includes a switching stage 12 and a correction stage 16, these stages feeding the amplifier 2 through a combiner 17. The feedback circuit 65 for the switching stage 12 uses a current feedback signal 70 from the output of the correction stage 16 when the envelope signal has a low bandwidth and uses a current feedback signal 68 from the output of the switching stage 12 when the envelope signal has a high bandwidth. This improves efficiency because at high bandwidths the output of the correction stage 16 causes excessively fast switching of the switching stage 12. The bandwidth of the envelope signal is detected by a circuit 19.  The switching stage may comprise a boost capacitor (40, figure 6) and may provide only three output voltage levels. To further improve efficiency the comparator 66 controlling the switch stage 12 may be constrained to change the output of the switching stage between adjacent output voltage states only.

Title: Communication system
Inventor: Caroline liang
IPC: H04B7/02
Filed: 2015-06-12
Abstract: A communication system 1 is disclosed in which coordinated multi-point transmissions for a mobile device 3 are carried out in two stages. In the first stage, a central controller 10 obtains Channel State Information (CSI) reports from multiple transmission points 5-1, 5-2, 5-3, based on which the controller 10 estimates respective data rates for transmissions between each transmission point 5-1, 5-2, 5-3 and the mobile device 3. The controller 10 determines an active set of transmission points 5-1, 5-2 to be associated with the mobile device 3, and informs the transmission points 5-1, 5-2 about the association made. In the second stage, the transmission points 5-1, 5-2 included in the active set carry out scheduling for the mobile device 3 independently from each other until the controller 10 updates the active set of transmission points 5-1, 5-2, 5-3.

Title: Methods and apparatuses relating to the handling of a plurality of content streams
Inventor: PAYMAN AFLAKI-BENI
IPC: H04N7/18
Filed: 2015-12-23
Abstract: A method comprises selecting at least one content stream from a plurality of content streams based on at least one detected characteristic (property, parameter) associated with the content streams or an intended viewer of the content streams, each content stream being captured by a corresponding recording (e.g. camera) device and at least one of the plural content streams not being selected, and compressing data representing the at least one selected content stream such that the content has a lower quality (e.g. reduced resolution, by low-pass filtering, downsampling, sample domain quantization, transform domain quantization) compared to the content of the at least one non-selected content stream. Characteristics may relate to the recording (capture) devices, such as relative position, direction, or spatial or temporal resolution; content stream characteristics may include amount of high frequency components, disparity, presence of regions of interest (ROI) or motion. User or viewer related characteristics may also be used, such as user preference or user eye dominance. Predetermined distributions of selected and non-selected content streams for example, such that recording devices for selected and unselected streams are adjacent - may be used based one at least one detected characteristic. Stream data may generate asymmetric stereoscopic content.

Title: Lay-up head
Inventor: STEPHEN BARTON
IPC: B29C70/38
Filed: 2016-03-18
Abstract: There is disclosed a lay-up head (18, fig 1) for applying elongate fibre reinforcement material (14, fig 1) to an application surface (12, fig 1). The lay-up head comprises a guide eyelet 50 through which elongate fibre reinforcement material is arranged to pass into the lay-up head. The guide eyelet has an eyelet rim 54 forming a discontinuous contact surface 56 over which elongate fibre reinforcement material is arranged to pass. The discontinuous contact surface 56 may be a revolved surface (i.e. it has a constant cross-section), which may be formed by a plurality of ridges or ribs 60 that are distributed over the curved section 58. The ridges 60 result in the eyelet rim 54 having a profiled surface, in particular, a wavy or corrugated profile. When a tow passes over the discontinuous contact surface 56, it is only in contact with the peaks of the ridges 60, and not with the troughs formed between the ridges 60. This minimises the contact area between the tow and the eyelet rim 54. The eyelets 50 allow the lay-up head to tilt up and down about an axis and allow the lay-up head to twist about the axis, without the tows breaking.
