Abstract: A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.

Abstract: Techniques are discussed herein for detecting and managing faults occurring within various vehicle systems, to enable the vehicle to respond safely and appropriately to the faults. In examples, a constraint generator may receive sensor data associated with the operation of a vehicle in an environment. The constraint generator may perturb the sensor data to mimic particular sensor faults, and execute simulations to determine performance degradations of the vehicle systems associated with the particular sensor faults. Based on the performance degradations associated with sensor faults, the constraint generator may determine the appropriate constraints with limitations on the operation of the vehicle, and communicate the constraint parameters to the appropriate vehicle systems accordingly.

Abstract: In an embodiment, a volleyball training device includes a handle with two sliding grips. The sliding grips may each slide between one end of the handle and the center of the handle. The handle may include an anchor connected through its center. One or more foot straps, each including an anchor, may be connected to the handle anchor with a resistance band or strap. Two foot straps may be connected to the handle anchor with separate resistance bands, or by s single resistance band threaded through the handle anchor.

Abstract: Systems and methods are described that include receiving, in a tab strip generated by a web browser application, a request to generate a tab group, generating the tab group, in response to receiving the request, where the generating includes generating a tab group identifier for the tab group, enabling pausing or starting of an activity associated with a resource accessed by a browser tab within the tab group based on whether the tab group is collapsed or expanded, and storing metadata about the tab group and the browser tab included in the tab group. The systems and methods may further include causing display of the generated tab group in the tab strip with the tab group identifier depicted in at least a portion of a user interface associated with the browser tab where the generated tab group is configured for display based on the metadata.

Abstract: A pivotal vehicle child seat and associated method includes a base member with a top surface and vertically upstanding walls formed therewith. The top surface is countersunk below a top edge of the walls, such that a recessed cavity is formed therein, and a seat member is vertically stacked on top of the base member and has a bottom ridge within the recessed cavity. A mechanism lifts and swivels the seat member above the base member and about a vertically registered fulcrum axis centrally defined within the recessed cavity. The mechanism is maintained at a locked position so the user is required to actively maintain an actuating force traversing the fulcrum axis so that the bottom ridge remains elevated above the recessed cavity during swiveling procedures.
