Abstract: An automated storage and retrieval system includes a multi-level storage rack and a material handling robot, where the multi-level storage rack includes a plurality of cuboid cells and the material handling robot is configured to navigate along a vertical direction or a horizontal direction from a first cuboid cell to a second cuboid cell. When the navigation from the first cuboid cell to the second cuboid cell is along a vertical direction, a set of second engagement structures disposed at corners of the material handling robot are mated with a set of first engagement structures disposed along structural columns of the first cuboid cell. A rotation of the second engagement structures drives the material handling robot to vertically move along the structural columns of the first cuboid cell.

Abstract: A powered track attachment for a wheelchair is disclosed. In an example, the powered track attachment includes a frame supporting an electric motor. A wheel platform is attached to the frame and supports wheels on the wheelchair. At least one track system is provided having a plurality of individual track members. A majority of the plurality of individual track members have protrusions formed thereon. The plurality of individual track members linked together forming a continuous track. At least one drive cog of the at least one track system has a plurality of depressions formed therein. The plurality of depressions mate with the protrusions formed on the individual track members of the at least one track system. The at least one drive cog rotates under power of the electric motor to move the continuous track and thereby move the wheelchair across terrain.

Abstract: A connector assembly is disclosed for making a connection between a tubular adapter component and a port connector which, once connected to each other, are not able to be disassembled. At least one of the tubular adapter component or the port component may have at least one cutout section and the other may have a projecting tab. A tubular sleeve is positioned on the port component and is non-rotatable and non-removable from the port component. The tubular sleeve has at least one flexible cam locking post. When the adapter component is slidably engaged with the port component the cutout section and the projecting tab engage to prevent sliding withdrawal of the adapter component from the port component. The flexible cam locking post also engages with the cutout section and prevents the adapter component from rotating.

Abstract: A dermal reflectance sensor method and system for providing and calculating UV light absorbed and vitamin D produced by a patient is provided. The method and system allows for real-time accurate calculating of UV light absorbed and vitamin D produced. The method and system utilizes at least five parameters for capturing and calculating data related to the specific vitamin D production of a patient.
