Title: Image processing to detect abnormal eye conditions
Inventor: BARNARD NIGEL ANDREW SIMON
IPC: A61B3/14
Filed: 2012-05-23
Abstract: An electronic device for processing eye image data comprises a processor configured determine whether an abnormality exists in an image of a subjects eyes. A processor selects image data and pre-processes the image to determine whether it is suitable for further processing and provides an indication of suitability for processing. Images suitable for processing have a processing algorithm applied for determining one or more parameters of the eye features from a set of predetermined parameters and an eye condition identifier analyses said parameters of the eye features and generates data indicating whether an abnormality exists in an image. The eye image is of at least one eye and may be of both of a subjectâ  s eyes. The pre-processing may consider the size of features of the eyes and/or it may determine the position of the eyes in the image and provide negative indications if these are outside predetermined thresholds. The images may be obtained using a handheld camera.

Title: Determining the rotor position of a permanent-magnet rotor
Inventor: BATEMAN CHRISTOPHER JOHN
IPC: H02P6/16
Filed: 2012-06-12
Abstract: A method of determining the position of a rotor of a permanent-magnet motor comprises sequentially exciting and freewheeling a winding of the motor. The winding is freewheeled for a freewheel period in response to current in the winding exceeding a current limit. The method further comprises measuring a parameter corresponding to one of the magnitude of current in the winding at the end of the freewheel period, and an interval between the start or end of the freewheel period and the time at which the current in the winding exceed the current limit, and comparing the measured parameter against a threshold. The rotor is then determined to be at a predetermined position when the measured current is less than or greater than the threshold. The threshold may be adjusted according to the speed of the motor. Measuring or comparing the parameter may be suspended for a suspension period after determining that the rotor is at the predetermined position. The suspension period may be varied according to the speed of the motor.

Title: Improved borehole log data processing methods
Inventor: ELKINGTON PETER ADRIAN SPENCER
IPC: G01V11/00
Filed: 2013-03-28
Abstract: A method of processing borehole log data, to create one or more image logs, comprises the steps of: modelling the data as illumination value and surface reflectance value components of an image. This is then transformed to a logarithmic domain and a Fourier transform is obtained of the resulting logarithmic domain expression to obtain a Fourier domain expression. This is high-pass filtered and an inverse Fourier transform is obtained of the resulting filtered Fourier domain expression. An exponential operation on this result is performed to obtain a filtered image model expression, values of the filtered image model expression are mapped to respective colour values across the range of the filtered image log expression values; and the mapped colour values is displayed, printed, saved and/or transmitted as one or more image logs. In another aspect, the positional parameters of a virtual light source are specified as azimuthal and elevation angles, and the image is shaded as though the light source illuminates the image at these angles. In another aspect, multiple versions of the image are created having respectively differing static scales.

Title: Method and system for performing automated system tests
Inventor: ALEXANDER STEFAN
IPC: G06F11/36
Filed: 2013-04-09
Abstract: Disclose is a method of performing automated tests on a system under test (SUT). The method starts by, providing a set of test blocks (TB1-TBn), each test block triggering a user activity on the SUT, providing a status repository 130 containing data reflecting the current status of the SUT, providing a history log 140 which protocols data regarding the performed automated tests and therefore provides data necessary for tracing the test history. The test blocks are executed by performing iteratively the steps of, defining a subset of executable test blocks by evaluating preconditions mandatory for executing the test blocks based on the current status of the SUT, scoring the executable test blocks based on at least one scoring parameter, selecting a test block to be executed by randomly selecting a test block based on said scores, the probability of selection of a test block depending on the score. Executing the selected test block, updating the data of the status repository based on data of the system under test provided by the executed test block, and updating the data of the history log by adding data regarding the executed test block and the results of the test block execution in order to provide a possibility of repeating the automated tests starting at a certain status of the SUT.

Title: Limiting the devices with which a user can synchronise data in a cloud storage account to those on a list of devices
Inventor: KIANG ANDY
IPC: G06F17/30
Filed: 2013-04-03
Abstract: A user device sends a login request to a cloud based service. The request includes user details and a device identifier. The device identifier may be a CPU identifier. The service determines whether the device is currently authorised to synchronise with the users account by comparing the device identifier with a list of identifiers of devices that have already been authorised. If the device has been authorised, synchronisation with the device is enabled. Otherwise, the service determines whether the limit on the number of devices allowed to synchronise with the account has been reached. If not, the device is added to a list of authorised devices and synchronisation with the device is enabled. Otherwise, synchronisation is disabled. The service may send the device an authentication token, if synchronisation is enabled. Each account may have a different limit on the number of devices.

Title: Method and apparatus for identifying actual signal sources among a pluarity of signal sources with artefacts detection
Inventor: CITERIN JOHANN
IPC: G10L21/0272
Filed: 2013-10-16
Abstract: Signal (eg. sound or voice) sources (101, 102) are identified and separated by correlating artefacts detected at multiple sensors (eg. microphones 103-105) with source activity over time. Sources are first spatially localized (fig. 2) via eg. examining the density of peaks (figure 4) in a histogram representing accumulation over time of a 2D angular spectra curve specinst (Î¸,Ï†)(t) for horizontal angle Î¸ and vertical angle Ï†, and then temporal correlations between localized source activity is determined by eg. calculating the Minimum Mean Square Error (MMSE) between an activity vs. time plot and its linear regression line, with an activity parameter Ei(t) being normalised and compared to thresholds (figure 6). Artefacts from indirect reception are less apparent in the time-averaged activity (figure 5).
