Abstract: A technique for improved throughput at an access point (AP) involves when frames are received for transmission by the AP, queuing the frames for a particular station. A system constructed according to the technique may include an aggregation and queuing layer. Station queues may be processed by the aggregation and queuing layer before being given to radio hardware for transmission. In an illustrative embodiment, when frames are received by the aggregation and queuing layer, the packet will be assigned a target delivery time (TDT) and an acceptable delivery time (ADT). The TDT is the “ideal” time to transmit a frame, based on its jitter and throughput requirements. Frames are mapped on to a time axis for transmission by TDT. In an illustrative embodiment, each frame is mapped by priority, so that there are separate maps for voice, video, best effort, and background frames. There will be gaps between frames for transmission that can be used for aggregation.

Abstract: Forged cavity back iron-type clubs and oversize clubs are disclosed. These forged clubs have thin, durable hitting face and relatively large cavity volumes. These clubs have high rotational moments of inertia to minimize distance and accuracy penalties associated with off-center hits. Long irons with hitting face of about 0.100 inch thick are achievable by the present invention. Also disclosed are forged irons made from stainless steels and annealed to achieve the desired hardness and ductility. Further, an interchangeable pin suitable for use in the manufacture of any of a set of iron-type clubs without re-tooling is disclosed. The pin is sized and configured to fit within a through-bore such that an adhesive such as a flexible epoxy may be placed within the gaps to provide a vibration dampening effect.

Abstract: A method and a system are provided for the safe berthing of marine vessels in the high seas and other unprotected open waters. The invention allows a large vessel to be berthed alongside in close enough proximity to a marine structure so that conventional loading arm equipment may be used to load and unload the vessel under most environmental conditions. One or more floating dolphins moored to the bottom of the sea and provided with fendering means are used for berthing the vessel alongside to the marine structure. The preferred type of floating dolphin is a triangular semi-submersible moored buoyant structure comprising three buoyant column members, or “caissons”, arranged invertical fashion, three buoyant hull segments, or “pontoons”, that support and separate the column members and provide heave damping to the moored buoyant structure, and three horizontal bracing members that retain the tops of the column members in place.

Abstract: A method of synchronizing clocks in the stations of ad hoc and infrastructure networks includes providing a time stamp field in a header; reading the header by all stations in a network; extracting the time stamp information from the header by each station in the network as time information; sending extracted time information to a station clock; and adjusting the station clock as a function of the extracted time information. A system for synchronizing clocks in the stations of ad hoc and infrastructure networks includes a DLL having a comparator for receiving the time stamp information and a low-pass filter having a long time-constant for adjusting the station clock in a gradual manner; a time stamp field in a header; and time information extracted from the time stamp information of the header by each station in the network.

Abstract: Disclosed is a closed-cell polyisocyanurate foam composition capable of high compressive strength at temperatures up to 200° C. The new composition further exhibits no loss or degradation in conventional mechanical properties—less than that which impacts the intended use. The formulation of the present invention is based on the reaction product of a isocyanate and an epoxide resin catalyzed by a mixture of a tertiary amine and a cyclic amine. Compressive strength is augmented by incorporating a large fraction of a non-reactive bulk filler into the precursor polymer gel.

Abstract: A method is disclosed for calculating a transition monitor value for one or more milk-producing animals so as to enable its use in evaluating and optimally managing the health and productivity (i.e., the transition performance) of those individual animals and of their herds. An expected milk production is calculated for a given time period of a current lactation based both on the individual's performance in her previous lactation and on her current state. Transition monitor values are calculated as the difference between actual and expected milk production values. The transition monitor values can then be used to evaluate and to optimize the health and productivity of both individuals and herds of individuals and to make comparisons of transition monitor programs both within and between herds.

Abstract: A golf club head having portions of varying density is disclosed and claimed. The club head includes a body with a recess in the back between the heel and toe and extending toward the sole. An insert that is configured to matingly correspond to the recess is positioned within the recess. The insert has a lower specific gravity than the club head body, biasing the club head mass toward the club head perimeter. The insert can form a muscle of the club head. The club head is forged, and the recess is formed by machining. After the insert is positioned within the recess, the club head-insert combination is subjected to additional forging and finishing steps. The present invention increases the club head moment of inertia and/or enlarges the club head sweet spot while retaining the golfer's ability to work the golf ball and shape the golf shot. The present invention can be used with forged, blade, and muscle back clubs, which have not heretofore been enhanced in these manners.

Abstract: A method is described for use with a server serving requested records among a multiplicity of records, and with a predetermined list of record identifiers, and with a first file containing information about records corresponding to the record identifiers. The method comprises the steps of: selecting at least two of the record identifiers from the list; for each one record identifier of the record identifiers: presenting a request to the server with respect to the record identifier; receiving a record from the server, said record corresponding to the record identifier; parsing the record, thereby deriving received information of interest from the record; comparing the received information of interest with corresponding information in the first file; and annunciating any difference between the received information of interest and the corresponding information in the first file.

Abstract: An operator system and related methods for automatically controlling access barriers including a controller associated with at least one access barrier and a transceiver associated with the controller for transmitting and receiving operational signals. The system also includes at least one proximity device capable of communicating operational signals with the transceiver based upon a position of the proximity device with respect to the barrier, wherein the controller monitors the operational signals and controls the position of the access barrier based upon the operation signals. Such a system allows for hands-free operation of the access barrier. Ground loop detectors and a global positioning system may also be incorporated into the system. And the system may be used to control the directional flow of traffic on a one-way road.
