Abstract: The disclosure describes implementations of an apparatus including a plurality of racks, wherein each rack houses a plurality of networking devices and each networking device includes a communication port. An optical circuit switch can be coupled to each of the plurality of communication ports in one or more of the plurality of racks, and a plurality of top-of-rack (TOR) switches can be coupled to the optical circuit switch. Other implementations are disclosed and claimed.

Abstract: A kneeboard formed of upper and lower polymeric shells about a core material and having a internal, generally vertical stiffener to impart strength to the kneeboard and to provide a low profile strengthened kneeboard.

Abstract: A prosthetic joint connector assembly includes a pylon having a first end and an outwardly flared portion adjacent to a second end thereof. The second end of the pylon is closed by a convexly domed surface which forms a concave interior surface and has a generally axial opening formed therein. The prosthetic joint connector further includes a securing nut carried internally of the pylon and an abutment also carried internally of the pylon. The securing nut is defined by a cylindrical member having a first end and an outwardly flared portion adjacent to a second end which terminates in a convexly domed surface. The securing nut also has an internally threaded axial bore extending at least partially therethrough. The first end of the securing nut has a bearing surface for engaging the abutment such that the securing nut is interposed between the abutment and the concave interior surface of the second end of the pylon.

Abstract: A peck feed drill incorporates a motor gear quill and a feed control assembly together on a moving race track shaped piston. External construction of the housing permits mounting of an indexing adaptor plug for attachment of drill bushings. Internal construction of the housing provides for passage of air to the various components to which control tool operation. Valves within the air logic circuitry are multi-functional to minimize the number of parts.
