Title: Identifying a speaker via mouth movement and generating a still image
Inventor: KIM EUN-YOUNG
IPC: G06F17/30
Filed: 2011-12-16
Abstract: photographing apparatus recognizes the shape of a speaker's mouth in order to identify a speaker area. That is, a person in a group could be identified as the speaker by the movement of their mouth and lips. A still image of the speaker area is then generated (P1-P3). The method can selectively perform image signal processing (ISP) with respect to the detected speaker area in a moving image. The ISP may include out-of-focusing, macro zooming, and macro focusing. The apparatus may enhance a moving image by generating a still image including the speaker area and using the still image as a bookmark. The speakerâ  s voice may also be used to identify the speaker area.

Title: Echo suppression in an audio signal
Inventor: AHGREN PER
IPC: G10L21/0208
Filed: 2012-12-21
Abstract: An audio signal outputted from eg. a speaker 210 on a hands-free phone is received at eg. a microphone 212 and the echo cancelled by modelling the echo path according to a Finite Impulse Response (FIR) model 304 and a second, different model (eg. an exponential model) 308.

Title: Redundant safety control system with sensors connected to active channel
Inventor: NOBELEN FLORENT
IPC: F01D21/00
Filed: 2013-01-30
Abstract: A safety device for controlling an engine M comprises first and second sensors e.g. variable resistance temperature sensors C1, C2, and at least two channels V1, V2 for processing data measured by sensors C1, C2. Each of the channels comprises a command module K1, K2 and a power supply Al, A2. A relay R1, R2 at the input to each channel connects the sensor to the active channel, so that both sensors are only connected to the input and power supply of the active channel. The active channel V1, V2 sends a command signal to its respective relay R1, R2, to connect the respective sensor C1, C2 to the active channel. The passive channel does not send a command signal to its relay, and the relay defaults to connect its associated sensor to the other, active, channel. This ensures redundancy of sensors, even in the event of a channel malfunction. Accuracy is improved by connecting each sensor to only one channel at any time.

Title: Generation of electricity from exhaust gas
Inventor: HAUGHTON ANDREW JOHN
IPC: F02B41/10
Filed: 2013-10-22
Abstract: A turbo-generator system generates electricity from the exhaust gas of an internal combustion engine 1. The electric current generated by the generator 11 (e.g. a switched reluctance machine) is controlled so as to maintain the turbine 3 at a first preset rotational speed. The amount of electric current demanded from the generator 11 is limited or reduced if the electrical system 17 cannot accept a greater electric current or if the exhaust gas pressure upstream of the turbine 3 is too great. In such cases, the proportion of the exhaust gas permitted to bypass the turbine 3 is controlled so as to maintain the turbine 3 at a second pre-set rotational speed that is slightly greater than the first. The turbines preset speeds are chosen to maximise electrical generating efficiency and for turbine safety. The system maximises the amount of electricity generated, avoids excessive exhaust gas back-pressure on the engine 1, and avoids overloading the electrical system 17. The turbine 3 may be located downstream of a turbocharger 7.

Title: Enhancing results by combing distributed acoustic sensing with seismic survey data
Inventor: FARHADIROUSHAN MAHMOUD
IPC: E21B43/16
Filed: 2013-11-04
Abstract: A method for the processing and interpretation of seismic survey data, by correlating or otherwise comparing or associating seismic data obtained from a seismic survey 90 with flow information obtained from distributed acoustic sensing(DAS)10 of a well or borehole 12 in the surveyed area. Embodiments of the invention allow for flow data representing a flow profile along a well that is being monitored by a distributed acoustic sensor to be determined, such that regions of higher flow in the well can be determined. By determining a flow rate profile along the well using the DAS then this provides information as to where in the perforated production zone oil is entering the well, and hence the location of oil bearing sands. This location can then be combined or otherwise correlated, used, or associated with petroleum reservoir location information obtained from the seismic survey, to improve the confidence and/or accuracy in the determined petroleum reservoir location. Also disclosed is a method for enhanced oil recovery which comprises injecting water into an underground reservoir provided with a borehole and monitoring with DAS whether oil or water is being received at one or more parts of the well.

Title: Method for measurement of ion events
Inventor: MOULDS RICHARD BARRINGTON
IPC: H01J49/00
Filed: 2013-11-27
Abstract: A method of processing a data stream including at least one data peak comprises extrapolating a segment of the peak 2 which has an amplitude or intensity above a threshold 4 in order to estimate the amplitude of the segments of the peak (5, 6) which have an amplitude less than said threshold 4. The extrapolation is carried out based on the shape of the peak, and may include fitting a linear growth function at an leading edge 7 and an exponential decay function at an trailing edge 8 until the extrapolated amplitude is equal to a baseline 9 or zero. A compensated data stream may then be generated using the peak data above the threshold 4 and the extrapolated peak data. The method is suitable for filtering or removing background noise 3 or spontaneous detector events 12 in a signal output from an ion detector e.g. an analogue to digital converter ADC.

Title: Chemical ionization with reactant ion formation at atmospheric pressure in a mass spectrometer
Inventor: BENTER THORSTEN
IPC: H01J49/14
Filed: 2014-04-23
Abstract: The invention relates to the production of water cluster ions ("hydronium clusters") at atmospheric pressure for the chemical ionization of analyte molecules, said cluster ions being generated using a corona discharge 10 at the Taylor cone of an aqueous liquid, preferably pure or slightly acidified pure water. The hydronium clusters of the form [H(H2O)n]+ are produced in a discharge chamber 6, which is separate from the ionization chamber, and introduced into the ionization chamber through a capillary 12. In the ionization chamber, the hydronium clusters can be heated and reduced in size by means of electrical acceleration and gas collisions, and thus made more reactive in order that analyte molecules of low proton affinity can also be ionized.
