Abstract: The present disclosure relates to classifying and/or selecting images based on image segmentation. A classification system for classifying images includes one or more processors and at least one memory storing machine executable instructions. When the instructions are executed by the one or more processors, they cause the classification system to: access image segmentation scores for pixels of an image, and classify the entire image based on the image segmentation scores for the pixels of the image. The image segmentation scores for the pixels of the image are provided by an image segmentation system based on the image, and each of the image segmentation scores correspond to at least one pixel of the pixels of the image.

Abstract: A control circuit for controlling a state of a switching circuit may include a first unit to sense and interpret a wireless signal or physical parameter as an “on” signal to transition the switching circuit to the “on” state, or as an “off” signal to transition the switching circuit to the “off” state, and to transfer a first digital signal or logic value and/or a second digital signal or logic value, which may respectively or combinatorially represent the “on” signal or the “off” signal, to a second unit via a first output and/or a second output of the first unit, respectively. The second unit may force a control input of the switching circuit to a logic value which is a function of the first digital signal or value and/or second digital signal or value and congruent with the state to which the switching circuit is to be transitioned.

Abstract: Capsule (60) moves through the gastrointestinal tract (62) in a first pass to generate a map of the gastrointestinal tract, and to identify a location of interest. In its second pass, capsule (60) moves through the gastrointestinal tract, and is controlled to perform a job at the identified location. Repeated localizations generate generate a map of the route taken by the capsule in the gastrointestinal tract (62). images displayed on the image monitor (61) are compared with the generated map displayed on the position monitor (63) to identify the location of a pathology (72).

Abstract: A system and method for measuring and analyzing motility within a body lumen such as the gastrointestinal (GI) tract, where an in vivo imaging device such as a capsule captures images and transmits the images to a processor, which calculates the motility of the device based on comparison of the images. Preferably, the processor compares the intensity of pairs of images or of elements of pairs of images, generates a variance for the compared images, and calculates the motility of the imaging device from the variances. The motility data may be presented to a user in various manners; for example, a plot of motility over time may be generated, or indications of low motility may be presented to the user of the system.

Abstract: The present invention provides an optical system for illuminating and viewing a target in which an illumination element and a receiving means are disposed behind a single optical window, and which obtains data essentially free of backscatter and stray light. The optical window of the optical system is configured such that it defines a shape having at least one focal curve, i.e., an ellipsoid shaped dome. The illumination element and the receiving means are geometrically positioned on the focal curve plane or in proximity of the focal curve plane, such that, when illuminating, rays from the illumination elements, that are internally reflected from the optical window, will not be incident on the receiving means.

Abstract: It is an object of the present invention to provide a device and method for controlled positioning and/or releasing an object in a body lumen. The device of the invention comprises a liquid filled tube detachably connected to an injecting apparatus at its proximal end and to a holding and releasing unit having a bore configured to hold and release the object, at its distal end. The holding and releasing unit is connected to the tube such that liquid can pass from the tube into the holding and releasing unit bore. The distal end of the tube is capable of being inserted and maneuvered through a body lumen. The object is retained in the device during its manipulation through the body lumen due to frictional force exerted by the holding and releasing unit on the object. The object is released by activating the injecting apparatus to achieve an hydraulic pressure in the holding and releasing unit bore which is higher than the frictional force.
