Abstract: An apparatus and methods are provided for a floating register wheel to provide cooling to brake system components of a vehicle. The floating register wheel includes a barrel for mounting a tire, an outboard face for fastening the barrel to a wheel hub of the vehicle, and vents in the outboard face to provide cooling to the brake system components. The outboard face includes a surface register for fastening the outboard face to the barrel and a floating register that includes the vents. Spokes join the surface register and the floating register to a hub for fastening the wheel to the vehicle. The floating register is outboard of the surface register to provide openings between the floating register and the surface register. The openings allow air to flow from the vents to openings between the spokes to extract heated air from the brake system components during operating the vehicle.

Abstract: According to one embodiment, a modular toy assembly system featuring one or more bases and a plurality of posts. Coupled to recessed connectors of the base, the plurality of posts includes a first end connector and a second end connector for coupling to different bases to provide depth of the toy. The posts include a first elongated body element and a second elongated body element interposed and extending between the first end connector and the second end connector. The first elongated body element and the second elongated body element are oriented to produce (i) a first slot between a first side of first elongated body element and a first side of the second elongated body element and (ii) a second slot between a second side of first elongated body element and a second side of the second elongated body element.

Abstract: According to one embodiment, a toy figure featuring at least a body element, a head support element, a head element, and a head covering element. The head support element includes a second connector for coupling with a first connector of the body element. The head support element includes a base partially surrounded by sidewalls extending upwardly from a perimeter of the base to form a cavity and an opening between these sidewalls. The head element includes a conduit for slidably engaging the second connector and residing within the cavity. The head element includes a plurality of facial expressions, each placed on a different sidewall of the head element. A selected facial expression is aligned with the opening of the head support element. The plurality of facial expressions enables alteration of the selected facial expression of the toy figure based on rotation of the head element.

Abstract: Antimony-based semiconductor devices are formed over a substrate structure (10) that includes an antimony-based buffer layer (24) and an antimony-based buffer cap (26). Multiple epitaxial layers (30-42) formed over the substrate structure (10) are dry etched to form device mesas (12) and the buffer cap (26) provides a desirably smooth mesa floor and electrical isolation around the mesas.
