Abstract: The present disclosure relates to a multi-model object segmentation system that provides a multi-model object segmentation framework for automatically segmenting objects in digital images. In one or more implementations, the multi-model object segmentation system utilizes different types of object segmentation models to determine a comprehensive set of object masks for a digital image. In various implementations, the multi-model object segmentation system further improves and refines object masks in the set of object masks utilizing specialized object segmentation models, which results in more improved accuracy and precision with respect to object selection within the digital image. Further, in some implementations, the multi-model object segmentation system generates object masks for portions of a digital image otherwise not captured by various object segmentation models.

Abstract: Described is a toy figure with activated components that are activated by wearable accessories. For example, a wearable ring can be positioned onto a toy figure as a mask or helmet, such that upon positioning the wearable ring upon the toy figure, the toy figure is activated to perform a function. The function is an action, such as causing the toy figure to reveal or expose a toy weapon (e.g., sword, gun, etc.), thereby allowing a user to engage in a variety of game play.

Abstract: A multi-component snap assembly is disclosed herein in which a snap flange has a snap nose with a contact face including a relief.

Abstract: An ultrasound probe has an acoustic window (10) or lens (20) through which ultrasound is transmitted and received by a transducer array (30) located behind the lens or window inside a probe enclosure. The external, patient-contacting surface (24) of the acoustic lens or window is textured. The texturing of the surface of the lens or window better retains gel spread over the lens or window for an ultrasound procedure, reduces reverberation artifacts, and diminishes the appearance of scratches on the lens or window.

Abstract: Cover assemblies for railroad cars are disclosed. In some embodiments, the cover assemblies include a cover pivotably movable between closed and open positions. The cover assemblies additionally include a lid stop assembly including a release handle positioned adjacent to a cover handle and a first locking element operatively connected to the release handle. The lid stop assembly additionally includes a second locking element attached to, or formed with, the housing. The first locking element moves between a locking position in which the first locking element engages the second locking element to secure the cover in the open position, and a releasing position in which the first locking element is spaced from the second locking element allowing the cover to be moved from the open position toward the closed position. The release handle allowing the user to move the first locking element between the locking and releasing positions.

Abstract: A medical imaging system configured to analyze an acquired image to determine the imaging plane and orientation of the image. The medical imaging system may be further configured to determine a location of an aperture to acquire a key anatomical view and transmit instructions to a controller to move the aperture to the location. A sonographer may not need to move the ultrasound probe for the medical imaging system to move the aperture to the location. An ultrasound probe may include a transducer array that may have one or more degrees of freedom of movement within the probe. The transducer array may be translated by one or more motors that receive instructions from the controller to position the aperture.

The first annular segment, the second annular segment, the vane, and the curved segment define a channel passing through the cage.

Abstract: An ultrasound probe including an active thermal management system is disclosed. The active thermal management system may include a fluid chamber coupled to a transducer assembly of the ultrasound probe. The fluid chamber may include a coolant that may dissipate heat from the transducer assembly. The active thermal management system may further include a heat sink coupled to the fluid chamber and thermal management system. The heat sink may include fins that extend into the coolant. The coolant may be a liquid or a gas. The coolant may be circulated within the fluid chamber by a circulation device. The circulation device may be a pump, a fan, or an impeller. An ultrasound probe may further include a window that forms an enclosure over the lens of the transducer assembly. The enclosure may be fluidly coupled to the fluid chamber and filled with coolant to dissipate heat from the lens.

Abstract: Manway assemblies for railroad tank cars are disclosed. In some embodiments, the manway assemblies include a cover having a perimeter portion with a plurality of spaced grooves. The manway assemblies additionally include a plurality of spaced fasteners pivotably attached to the nozzle adjacent to the opening. The manway assemblies further include an interference member attached to the cover adjacent to at least one groove. The interference member prevents pivoting of the at least one fastener from a secured position in which the fastener is received in a corresponding groove, to an unsecured position in which the fastener is spaced from the corresponding groove when the cover is in a closed position. The interference member allows pivoting of the at least one fastener from the secured position to the unsecured position when the cover is in a partially open position in which pressure contained within the railroad tank car is vented.
