The upper joint component comprises an upper contact surface and an upper articulation surface. The system further includes a lower joint component. The lower joint component comprises a lower contact surface and a lower articulation surface configured to movably engage the upper articulation surface to form an articulating joint. The articulating joint is adapted for implantation within a disc space between the upper and lower vertebrae, allowing the upper and lower vertebrae to move relative to one another. The system further includes a bridge component extending posteriorly from one of either the upper or lower joint components and from the disc space. The bridge component has a distal end opposite the one of the either upper or lower joint components. The distal end of the bridge component comprises a connection component adapted to receive a fastener.

Abstract: A collapsible play yard including a structural support frame, a liner attached to the frame and one or more folding systems. The structural support frame includes an upper frame and a plurality of leg members. The proximal end of each leg member attaches to the upper frame member which is the single point of contact between the leg member and the remainder of the frame. The collapsible play yard can include a first folding system to shorten the width of the play yard and a second folding system to shorten the height of the play yard. Each folding system can be folded and unfolded independent of the other.

Abstract: A child support device (200) includes a seat (204) and a panel (208) included in or adjacent to the seat. The panel includes a first panel portion (212) including a panel edge (216) defining a panel opening. The first panel portion has a first heat transfer coefficient. A location of the panel opening corresponds to a heat transfer region in which an expected heat received from a child in the seat is greater than a heat reception threshold, A second panel portion is in the panel opening and attached to the panel edge. The second panel portion includes a layered mesh having a second heat transfer coefficient greater than the first heat transfer coefficient and greater than a threshold heat transfer coefficient at which a temperature of the second panel portion while receiving the expected heat is greater than a room temperature by less than a threshold difference, wherein the threshold difference is at most five degrees Fahrenheit.

Abstract: A hinge mechanism and mattress for use with a child containment device. A first mattress panel is pivotally coupled to a second mattress panel by a hinge mechanism, and is thereby convertible between an expanded configuration and a collapsed configuration. The hinge mechanism defines a limit point beyond which pivotal motion is prevented in at least one direction.

Abstract: A child-supporting device including a child-seat assembly mounted to and supported by a rocker frame assembly. The seat assembly includes a backrest, a footrest, or both, pivotably adjustable between reclined and inclined positions. A recline adjustment mechanism is operable to selectively lock the seat in the reclined or inclined position for use, then release the seat for pivotal adjustment to the other position. In some embodiments, a linkage interconnects the backrest and the footrest so that pivoting one of them synchronously pivots the other one. And in some embodiments, the footrest is detachable and a quick connect/disconnect mechanism is provided that permits operation of the recline adjustment mechanism when the footrest is attached.

Abstract: An infant bed includes multiple base panels and multiple side and end panels extending therefrom, with the side and end panels typically including removable boards. Each of these panels is connected to adjacent of the panels along respective fold lines that enable the adjacent panels to be folded over on each other. By folding the panels in various ways, they can be converted from a flat configuration for use as an infant play mat to a receptacle configuration for use as an infant bed and/or to a collapsed configuration for transport. Various attachments, flaps, and/or other features can be included for securing the panels in the bed and/or transport configurations, and handles can be included for carrying the bed in the transport configuration. Also, the bed can be nested within a bassinet for use, and upon removal of the bed the bassinet can be collapsed to a transport configuration.
