Abstract: A method for generating sleep apnea information for a portion of body sensor data. The method of generating sleep apnea information is made dependent upon a determined presence or absence of arrhythmia within the portion of body sensor data. A first sleep apnea detection methodology is used in response to an absence of arrhythmia being detected within the portion of body sensor data.

Abstract: The specification describes an RNA vector. The vector may be derived from a plant virus or an umbravirus-like associated RNA such as Citrus yellow vein-associated virus (CYVaV). The vector contains a heterologous segment comprising a small interfering RNA (siRNA) that targets Xylella fastidiosa (Xf). In some examples, the heterologous segment may target the Xf PilG and/or TolC gene. The heterologous segment may be in the form of a hairpin structure inserted into a CYVaV-like molecule. A method of treating a plant against a disease caused by Xf includes introducing the vector into a plant before or after the plant is infected by Xf. The specification also describes a plant, or a portion of a plant, containing the vector and/or the heterologous segment. The plant may be a grapevine.

Abstract: A system is provided for determining a level of alertness of a subject, using a physiological sensor for providing physiological sensor signals which distinguish between a sleep state and an awake state of the subject. Sleep sessions are identified and their associated falling asleep and waking up times. A single representative midsleep time is obtained from multiple sleep sessions over a 24 hour period, and a circadian phase is estimated using the single representative midsleep time. A level of alertness is then obtained from the circadian phase. This system avoids the need for the use of a default circadian phase when determining a level of alertness. The system can more accurately estimate sleepiness for individuals that have irregular sleep patterns such as shift workers or people with sleep disorders. The single representative midsleep time is also able to take account of multiple sleep sessions, i.e. naps or periods of restless sleep.

Abstract: A method of generating a summary of an audio/visual data stream is provided, the data stream comprising a plurality of consecutive frames having audio and visual properties. A plurality of shots of an audio/visual data stream are detected (step 204). A plurality of segments of the audio/visual data stream are determined (step 206), each segment comprising a plurality of the shots of the data stream having similar visual properties. A segment of the determined plurality of segments is selected (step 208). For each shot of said selected segment of said data stream, the audio in a plurality of consecutive frames which occur after the end of said shot is extracted (step 210). At least one of the shots is selected based on the extracted audio (step 212). A summary is generated to include the selected at least one of the shots (step 214).

Abstract: The present invention relates to a an active pillow system and a method for manipulating a person's resting conditions, wherein the actual resting conditions of the person are determined by a sensor unit, an actigraph, a temperature sensor and/or a humidity sensor for instance, and wherein an acoustic synthetic jet cooling mechanism, is triggered by the determined actual resting conditions for manipulating the person's resting conditions.

Abstract: At least one region of interest within an image is determined, step 201. The image is resized to a target image size step 207. If at least one region of interest is determined the image is cropped to each of the at least one region of interest, step 205 and the cropped at least one region of interest is resized to the target image size. The re-sized image and the resized cropped at least one region of interest are stored for display, step 209.

Abstract: A method for determining a value of an attribute to be associated with an image, the method comprising the steps of: determining saturation of each of a plurality of pixels of an image; selecting a set of a plurality of pixels from the pixels of the image having a saturation above a predetermined level; determining a value of an attribute on the basis of the selected set of pixels; and associating the determined value of the attribute with the image.

Abstract: A method of determining a starting point (12) of a segment (11) corresponding to a semantic unit of an audiovisual signal includes processing an audio component of the signal to detect sections (14) satisfying a criterion for low audio power, and processing the audiovisual signal to identify boundaries of sections corresponding to shots. A video component of the audiovisual signal is processed to evaluate a criterion for identifying video sections formed by at least one shot of a certain type, comprising images in which an anchorperson is likely to be represented. If at least an end point of a section (14) satisfying the criterion for low audio power lies on a certain interval between boundaries of an identified video section (13), a point coinciding with a section (14) satisfying the criterion for low audio power and located between the boundaries of the identified video section is selected as a starting point (12) of a segment (11).

Abstract: A content augmentation process for personal recordings involves a service center (SC). The service center (SC) collects personal recordings from various different users via a network so as to constitute a database (DB) of personal recordings. The service center (SC) identifies personal recordings within the database (DB) that concern a particular scene and that are mutually complementary so as to form a selection of personal recordings (FSRR) for content augmentation purposes. The service center (SC) applies a content augmentation process (AUGP) to the selection of personal recordings (FSRR) so as to obtain an enhanced representation (CA).
