Abstract: Embodiments propose methods and system for predicting the occurrence of critical alarms in response to the occurrence of less severe, non-critical alarms. It is proposed to use a machine-learning model trained to discern whether a non-critical alarm will be followed by a critical alarm within a particular time period, e.g. whether the non-critical alarm will develop into a critical alarm. Unlike existing alarm systems which are merely threshold based, this approach uses physiological data from a window of data. This window of data can be expected to carry more information than a simple breach of the threshold.

Abstract: An ultrasound imaging system for needle insertion guidance uses a curved array transducer to scan an image field with unsteered beams as a needle is inserted into the image field. Due to differences in the angle of incidence between the radially directed beams and the needle, echoes will return most strongly from only a section of the needle. This section is identified in an image, and the angle of incidence producing the strongest returns is identified. Beams with this optimal angle of incidence are then steered in parallel from the curved array transducer to produce the best needle image. The steep steering angles of some of the steered beams can give rise to side lobe clutter artifacts, which can be identified and removed from the image data using dual apodization processing of the image data.

Abstract: A system and method is disclosed for measurement of pulse wave velocity of a vessel. An intravascular device comprises a first and a second marker provided at different locations along the length of the intravascular device of which positions are localizable by a tracking apparatus. The intravascular device provides plurality of measurements along the length of the vessel, while the intravascular device is moved from a first position to a second position, corresponding to a first and a second time.

Abstract: A brush, rotatably arranged in a cleaning device for cleaning surfaces, is described. The brush includes a core element and brush elements arranged on the core element. The brush elements are arranged in a bristle field extending in a direction of a longitudinal axis of the brush and in a peripheral direction about the longitudinal axis.

Abstract: A system and method are provided for warning of an exposure of a second individual to an allergen by transfer from a first individual. Movements of the individuals are tracked so that allergen types and levels to which the individuals have been exposed can be obtained. Using knowledge of user sensitivity information to different allergens, it is determined if the first individual has been exposed to allergen types and levels which pose a risk to the second individual by GPS transfer from the first individual to the second individual. Thus, action can be taken when there is a determined risk of allergen transfer between individuals.

Abstract: The application relates to the problem of navigating a surgical instrument (at 301, 311) towards a region-of-interest (at 312) in endoscopic surgery when an image (300) provided by the endoscope is obscured at least partly by obscuring matter (at 303), wherein the obscuring matter is a leaking body fluid, debris or smoke caused by ablation.

Abstract: A diagnostic ultrasound system has a 2D array transducer which is operated with 1×N patches, patches which are only a single element wide. The “N” length of the patches extends in the elevation direction of a scanned 2D image plane, with the single element width extending in the lateral (azimuth) direction. Focusing is done along each patch in the elevation direction by a microbeamformer, and focusing in the lateral (azimuth) direction is done by the system beamformer. The minimal width of each patch in the azimuth direction enables the production of images highly resolved in the azimuthal plane of a 2D image, including the reception of highly resolved multilines for high frame rate imaging.
