Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

Abstract: Various embodiments of a system and methods for labeling images are described. An image labeling system may receive multiple images. A subset of the images may be labeled to identify image content or elements, such as faces. The system may display some of the labeled image elements in different portions of a display area. Unlabeled image elements may be displayed in the same display area. The display size and position of each unlabeled image element may be dependent on similarities between the unlabeled image element and the displayed, labeled image elements. The system may receive input which indicates that one or more of the displayed, unlabeled image elements should receive the same label as one of the displayed, labeled image elements. Similarities between image elements may be re-analyzed, dependent on the assigned labels, and the display of unlabeled images may be updated.

Abstract: Various embodiments of a system and method for labeling images are described. An image labeling system may label multiple images, where each of the images may be labeled to identify image content or image elements, such as backgrounds or faces. The system may display some of the labeled image elements in different portions of a display area. Unlabeled image elements may be displayed in the same display area. The display size and position of each unlabeled image element may be dependent on similarities between the unlabeled image element and the displayed, labeled image elements. The system may also receive gesture input in order to determine a corresponding labeling task to perform.
