Abstract: Systems and techniques for generating and/or employing a medical imaging stroke model are presented. In one example, a system employs a convolutional neural network to generate output data regarding a brain anatomical region based on diffusion-weighted imaging (DWI) data associated with the brain anatomical region and apparent diffusion coefficient (ADC) data associated with the brain anatomical region. The system also detects presence or absence of a medical stroke condition associated with the brain anatomical region based on the output data.

Abstract: The invention relates to an actuator device for change of state of an electronic-control apparatus for underwater use and a system for underwater use comprising the combination of a said actuator device with an electronic-control apparatus for underwater use. The actuator device for change of state of an electronic-control apparatus for underwater use comprises a main body designed to be associated in a stable way with at least part of said apparatus.

Abstract: The present disclosure provides methods and systems directed to management and visualization of radiological data. A method for processing at least one medical image of a location of a body of a subject may comprise (a) retrieving, from a remote server via a network connection, the medical image; (b) identifying one or more regions of interest (ROIs) in the medical image, wherein the ROIs correspond to an anatomical structure of the location of the body of the subject; (c) annotating the ROIs with label information corresponding to the anatomical structure, thereby producing an annotated medical image; (d) generating educational information based at least in part on the annotated medical image; and (e) generating a visualization of the anatomical structure, based at least in part on the educational information.

Abstract: A second-stage regulator for scuba divers is disclosed that reduces considerably the inhalation effort required by the user through reduction in friction between selected components of the regulator. A flexible sleeve is sealingly connected to the regulator poppet and the baffle, and coaxially with the poppet, so as to avoid blow-by of gaseous mixture through an opening in the baffle. A tail of the poppet extends through the opening, the tail being connected to a lever of the regulator projecting into an outlet chamber thereof. The head of the poppet is or includes a ferrule with an at least partially-circular profile and abuts a selected inner portion of the inlet's intermediate chamber to allow oscillation of the poppet. The lever end of the regulator contacts a diaphragm, the diaphragm separating the outlet chamber from the external environment.

Abstract: A spear gun for scuba diving that comprises a frame with a body that is generally elongated along a longitudinal axis of the gun, and a grip at one end of and extending from the elongated body. The grip includes a stationary part attached to, and integrally with, the body and a movable part adjustably mounted to the stationary part. A device is also provided for securing or locking the movable part to the stationary part when a desired grip configuration has been achieved.

Abstract: A device is provided for locking a front end of a spear shaft in a spear gun. The device comprises a bridge extending crosswise over a distal end of the gun with a substantially U-shaped nosepiece joined to the distal end and revolving relatively freely about a crosswise axis thereof. The nosepiece includes at least two arms connected to respective ends of a relatively elastic cable that may be tensioned against a rear end of the shaft, when the shaft is placed on a support surface along the body of the gun. The bridge is attached to and integrally with the ends of the elastic cable and is located a selected distance from the support surface such that the shaft is retained against the surface when the spear is in a stowed or loaded position.

Abstract: A device is provided for releasing a spear shaft of a spear gun for scuba diving or the like. The shaft has a latch element formed on a first lever pivotally connected at its front end to a screw attached to and integrally with a frame of the gun, the lever being maintained elastically in a resting position. The gun has a trigger with an abutment portion forced elastically against the front end of the first lever extending forward of a convex upper surface. The convex upper surface intersects a concave surface at an edge that traces a first circular trajectory when the trigger is rotated. A second lever is rotatably connected to the frame, the front end of the second lever being movable along a second circular trajectory intersecting the first circular trajectory.
