Abstract: Devices and processing systems are configured to enable physiological event prediction based on blepharometric data analysis. For example, some embodiments provide methods and associated technology that enable retrospective analysis of blepharometric data driving subsequent hardware/software configuration, thereby to provide for personalized and/or generalized biomarker identification.

Abstract: Blepharometric data (data describing eyelid position as a function of time) is recorded and processed for the purposes of predicting a future risk and/or current occurrence of neurological events such as seizures. For example, in one embodiment, blepharometric data is recorded via infrared reflectance oculography spectacles, and processed in real time thereby to extract a set of blepharometric artifacts. Where those artifacts indicate prolonged spiking in blink calmness (for example, based on spiking in negative inter-event duration, or negative IED), an alert is able to be generated thereby to indicate that the subject is at risk of a seizure in a proximal time period. This provides an opportunity to implement mitigation measures, for example, to reduce the likelihood of the seizure manifesting, and/or to mitigate harm should the seizure occur.

Abstract: The present invention relates, in various embodiments, to prediction of human subject states (e.g. physiological and/or psychological and/or neurological state) via a hybrid approach, which includes elements of AI-based classification and objective physiological analysis (such as blepharometric analysis). Embodiments are described by reference to applications in driver alertness monitoring. However, it will be appreciated that the technology is not limited as such, and has application in a broader range of context. For example, the technology is applicable to prediction of physiological states other than alertness level, and to implementation environments other than driver monitoring.

Abstract: Technology described herein relates to extended monitoring and analysis of subject neurological factors via blepharometric data collection, for example, including devices and processing systems configured to enable such extended monitoring. This may include hardware and software components deployed at subject locations (for example, in-vehicle monitoring systems, portable device monitoring systems, and so on), and cloud-based hardware and software (for example, cloud-based blepharometric data processing systems. The technology allows for user blepharometric data to be collected across a plurality of monitoring sessions, in some cases via different collection technologies, thereby to analyze changes over time. For example, this can assist in identifying risks of degenerative neurological conditions.

Abstract: Technology is adapted to enable improved collection of involuntary eyelid movement parameters, including collection of eyelid movement parameters to support analysis of neurological factors. For example, this may include methods and systems configured to enable improved analysis of involuntary eyelid movement parameters, including diagnosis of subject neurological conditions and/or other subject attributes from analysis of involuntary eyelid movement parameters. Some embodiments relate to testing, which provide a standardized environment for collection of involuntary eyelid movement data thereby to reduce influence of variable factors, which affect involuntary eyelid movement. For example, the standardized environment influences the subject to adopt a controlled cognitive and/or physiological state, thereby to improve comparability of test results.

Abstract: Lower sampling rates have been found to provide sufficient data for use in the method of U.S. Pat. Nos. 7,071,831, 7,616,125 and 7,791,491. The method of determining drowsiness includes the steps of receiving eye movement data collected at sampling rates as low as 20 Hz. The data is preferentially interpolated to provide a data set at a higher sampling rate in the order of 500 Hz. For each data point, values of amplitude and velocity of eye movement and whether the measures relate to eyelid opening or closing are derived. An algorithm is then used to obtain values of the amplitude to velocity ratios of eyelid opening and closing and using these values in an algorithm for providing a measure of drowsiness. With this method eyelid and eye movement may be monitored using any suitable technology or sensor including video or digital camera technology to identify and measure the appropriate ocular movements.

Abstract: A computer implemented method for extracting meaningful text from a document of unknown or unspecified format. In a particular embodiment, the method includes reading the document, thereby to extract raw encoded text, analysing the raw encoded text, thereby to identify one or more text chunks, and for a given chunk, performing compression identification analysis to determine whether compression is likely. The method can further include performing a decompression process, performing an encoding identification process thereby to identify a likely character encoding protocol, and converting the chunk using the identified likely character encoding protocol, thereby to output the chunk as readable text.

Abstract: A dynamic information retrieval system for monitoring a conversation between two or more parties and automatically collecting a plurality of keywords used during the conversation. A priority is assigned to the plurality of keywords and an information database is automatically searched for information relevant to the conversation based on the plurality of keywords. A keyword list and an information list is displayed on a workstation display to allow an agent to directly select/deselect one or more of the plurality of keywords and/or information, wherein the priority of the one or more of the plurality of keywords and/or information may be adjusted. As keywords and/or information are selected/deselected, the keyword list and the information list are dynamically updated based on new priorities that may have been assigned to the plurality of keywords and information and/or how much time has passed since a keyword was mentioned.

Abstract: The present invention is directed to a radiographic apparatus that utilizes a single integral housing for providing an evacuated envelope for an anode and cathode assembly. The integral housing provides sufficient radiation blocking and heat transfer characteristics such that an additional external housing is not required. The integral housing is air cooled, and thus does not utilize any coolant. In addition, the integral housing is insulated with a potting material, which electrically insulates the integral housing and its components, and also limits the amount of noise emitted from the housing during operation. In an alternative embodiment, enhanced thermal and electrically insulating properties are achieved through the use of a potting material disposed in selected areas of the tube interior. The potting material cooperates with optimized airflow through the tube assembly to effectively and continuously remove heat therefrom.

Abstract: A method and apparatus for reducing off-focus radiation by modifying a shape of a rotating target anode disposed within a cathode grounded x-ray tube. The shape of the target anode body is modified such that surfaces of the target anode which could otherwise direct the greatest amounts of off-focus radiation toward an x-ray sensitive imaging device are angled or shortened so as to redirect the off-focus radiation away from a focal direction. These modifications to surfaces of the target anode body include modifying a front surface, a side or edge surface, and a back surface.
