The present invention is directed to a low latency fiber optic local area network with a network and a plurality of nodes connected through optical fibers. Each node has a plurality of bi-directional input/output interfaces. Each bi-directional input/output interface has a demultiplexer, at least one optical power coupler, a plurality of wavelength converters, and a plurality of internal optical waveguides. The internal optical waveguides extend from each wavelength converter and are for communication with the demultiplexer, the input fiber optic interface, and the optical fiber. Each optical power coupler has a fiber optic output interface for communication with other nodes, and each demultiplexer has a input fiber optic interface for communication with other nodes.

Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: a shaft adapter, a collet, a ferrule, and a club head having an interior chamber. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts.

A furling system adapted for use with an air cushion landing system (ACLS) coupled to a hull of an airship is disclosed. The furling system includes a deployable cover having two lateral edges. The cover is configured to cover at least a first portion of the ACLS when the cover is deployed. The furling system also includes a fairing that has an inlet and is coupled to the hull of the airship. The furling system also includes a pair of cables each coupled to at least one point along respective lateral edges of the cover. The pair of cables is configured to selectably draw the cover into the fairing through the inlet when the pair of cables is activated in a first direction, thereby stowing the cover and exposing the ACLS.

Golf club and golf club head structures include a ball striking face, a frame member and a perimeter stiffening element. The frame member may extend rearwardly from a perimeter of the ball striking face. The perimeter stiffening element may extend along at least a portion of the perimeter of the ball striking face and further may extend from the ball striking face to the frame member. The thickness of the ball striking face may be less than or equal to 2.0 mm. The cross-sectional area of the perimeter stiffening element may be greater than or equal to 10 mm2. The golf club head may be a wood-type club head.

A ball striking device, such as a golf club, includes a head that includes a face having a ball striking surface configured for striking a ball and a body connected to the face and extending rearward from the face. A face member formed primarily of a metallic material forms the face, and a body member is connected to the face member and extends rearward from the face member to form at least a portion of the body. The body member is formed at least partially of a polymer material, and has a doped portion containing a doping material dispersed within the polymer material. The doping material may have a different density than the polymer material, such that the doped portion has a different density than the portions of the body member not containing the doping material. A co-molding method may be used to form the ball striking device.

Wood-type golf club heads include: (a) a club head body including heel, toe, crown, sole, and weighted rear portions; and (b) a variable thickness ball striking face. The club head body parts and weighted portion(s) may be arranged such that the club head has a moment of inertia about a vertical axis passing through the club head center of gravity of at least 5000 g-cm2. Such club heads may include: (a) a cup face member including a ball striking face portion and a return portion; (b) sole and crown portions engaged with the return portion; (c) a rear body member engaged with the crown and/or sole portions; (d) a weight member at the club head rear; and/or (e) a hosel member engaged with the cup face member, the crown portion, and/or the sole portion. Methods of making such club heads also are described.

Wood-type golf clubs as described herein may include: (a) a hosel to receive a golf club shaft; (b) a club head; and (c) a ball striking face. The club head include may include: a plurality of weights, a plurality of tubes, and an exterior cover structure (e.g., an exterior skin) that covers at least a portion of the plurality of weights and at least a portion of the plurality of tubes, and wherein the exterior cover structure defines the shape of the club head. Additionally, the ball striking face may be engaged with at least two of the plurality of weights and/or at least two of the tubes. The plurality of weights may include a first weight, a second weight, a third weight, and a fourth weight that are all engaged with the striking face.

A cavity back golf club and golf club head having one or more support brackets is disclosed. Each support bracket includes a first portion engaged with the rear surface of the striking face, a second portion engaged with the perimeter weighting member, and a third portion that is curved. The one or more of the support brackets are engaged with a rear surface of a striking face and a perimeter weight member of the golf club head. The one or more support brackets are at least partially located in a rear cavity of the golf club head. The support brackets provide structural integrity to a thin striking face on the golf club head. Additionally, a discretionary weight is engaged with the at least one of the support brackets at the toe portion of the golf club head.
