A scheduler in a network device serves ports with data units from a plurality of queues. The scheduler implements a scheduling algorithm that is normally constrained to releasing data to a port no more frequently than at a default maximum service rate.

Ray tracing hardware accelerators supporting multiple specifiers for controlling the traversal of a ray tracing acceleration data structure are disclosed. For example, traversal efficiency and complex ray tracing effects can be achieved by specifying traversals through such data structures using both programmable ray operations and explicit node masking. The explicit node masking utilizes dedicated fields in the ray and in nodes of the acceleration data structure to control traversals. Ray operations, however, are programmable per ray using opcodes and additional parameters to control traversals. Traversal efficiency is improved by enabling more aggressive culling of parts of the data structure based on the combination of explicit node masking and programmable ray operations. More complex ray tracing effects are enabled by providing for dynamic selection of nodes based on individual ray characteristics.

Sliding operator assemblies and associated fenestration units, systems, and methods of use and assembly are described. Some such sliding operator assemblies transition a first, linear actuation force along a first axis (e.g., vertical) to a second actuation force along a second axis (e.g., horizontal) to cause a drive mechanism to impart opening and closing forces, respectively, on the sash. Some designs relate to belt-, twisted ribbon-, or band-drive sliding operator assemblies.

The present invention is a novel hinge design that allows unique operation of the lid for a container, box, storage chest, ice chest or similar item. In addition to the lid being able to flip up on two hinges as is traditional, the present invention allows the lid to swivel to one side or the other, while remaining in the horizontal plane. This is accomplished, in the exemplary embodiment, by means of two inventive ball-and-socket hinges each of which can have its ball disengaged from its socket. If one ball-and-socket hinge is thus disengaged, the lid is then free to rotate horizontally around the other ball-and-socket hinge, thereby swiveling the lid to one side and effectively opening the box or container. The lid, when opened in this fashion, is amply supported by the end of the box over which it sits, and can act as a table or flat surface for organizing items as they are transferred to or from the box or container. The horizontal lid can swivel in either direction, providing broad access to either end of the container. If broader access is desired, the lid can also be completely removed by simultaneously disengaging both hinges.
