Title: Load sharing for redundant networks
Inventor: FEE BRENDAN J
IPC: H04L12/56
Filed: 1997-08-14
Abstract: Method and apparatus providing for load sharing in redundant communication networks. The method and apparatus may include detection of redundant communication links in the network topology and sharing communication load over those links. This may be accomplished through assignment of unique labels to each link in a group of redundant links and assignment to each data packet of a value corresponding to the label on just one of the links; the packet being forwarded on only that link. The method and apparatus are also suited to quick recovery from a change in state of a network topology.

Title: Small envelope tamper-resistant spring brake actuator
Inventor: CHOINSKI GRAYDON
IPC: F16D65/18
Filed: 1997-09-25
Abstract: A small envelope is achieved for an inelastically deformed connection between a spring cover (22) and a central housing in a spring brake actuator. The connection is deformed radially inwardly (32) and then extends radially outwardly (31) from the radially inwardly extending portion. This eliminates the radially outwardly extending portion and flanges as are typically utilized in the prior art. Thus, a much smaller enveloppe is provided. In preferred embodiments of this invention, a seal groove (36) is positioned axially adjacent a securement groove in the central housing. A seal (34) is positioned in the seal groove to ensure an air-tight seal. In addition, a unique diaphragm guiding structure (62) is incorporated into one embodiment of this invention.

Inventor: KOLLER ERNST
IPC: E04B1/24
Filed: 1999-05-27
Abstract: An I-beam with a main beam body and a head at each end. The heads are symmetrical widthwise laterally of the beam body with each head having an outwardly facing side shaped to define two identical, longitudinally outwardly facing grooves. Each groove is shaped by longitudinally outwardly facing ribs and by transverse ribs at the free ends of the first mentioned ribs to define an opening into an undercut region inside the groove. The heights of the ribs are selected relative to the width of the grooves so that the height of the laterally outer rib of one beam fits into the height of the undercut of the groove of the other beam when the rib of one beam is installed in the groove of the other. The ribs in the grooves are shaped to support the rib of the head of one beam in the groove of the other when the beam bodies are at right angles. In an alternative design, there may be a third groove between the two outer grooves.

Title: Method and apparatus for correcting effects of ship motion in marine seismololgy measurements
Inventor: ALLEN KENNETH PAUL
IPC: G01V1/38
Filed: 1999-07-21
Abstract: An apparatus and method for removing the distortion in marine seismic data resulting from the motion of the ship. The ship trails one or more seismic sources and receivers and moves forward at a known velocity. The seismic sources emit seismic waves that travel through the water and reflect off interfaces between rock formations below the ocean floor. The motion of the sources and receivers introduces distortion in the recorded seismic data that can be modeled using Doppler theory. The data preferably is corrected for source motion independently from the correction for receiver motion. The seismic data is first corrected for receiver motion and then for source motion The technique for correcting for source motion includes correlating the receiver-corrected data with a reference sweep signal, performing an F-K transform, performing an inverse F-K transform on a selected subset of the F-K transformed data, and computing appropriate correction filters for the data resulting from the inverse F-K transform. This process is repeated for all subsets of F-K  transformed data and the resulting filtered data are summed together.

Title: Digital signal framing systems and methods
Inventor: COADY ALAN CHARLES
IPC: H04J3/06
Filed: 1999-07-27
Abstract: A method and apparatus for detecting framing alignment sequence within a received bit stream. A stream state memory is assigned for each possible location of the framing alignment sequence. Bits of a particular stream are loaded into the respective stream state memory. If the bits do not match an acceptable subsequence of the framing alignment sequence then the stream is eliminated from consideration by writing an exile state to the respective stream state memory. Then subsequently received bits are used to transition either to the next state if the next bit is a correct bit in the framing alignment sequence, or to the exile state if the bit is not the correct bit. After all of the streams have been exiled but one, the remaining stream may contain the framing alignment sequence. However, it may be that a certain number of correctly received bits are required to declare in-frame with sufficient certainty in which case incoming bits will continue to be processed until this is satisfied. Examples are given relating to DS1 superframe and extended superframe framing alignment sequences.

Title: Method and apparatus for providing an edging structure for pavement
Inventor: ZWIER DANIEL G
IPC: E01C11/08
Filed: 1999-07-23
Abstract: A pavement restraint structure includes edging pieces having apertures. Connecting elements have protrusions that are secured in the edging apertures such that adjacent edging pieces have a gap therebetween.  Anchoring elements are received by slotted apertures in the edging pieces. Thus, the arrangement enables movement, such as contraction and expansion of the edging pieces along a length thereof. Such movement prevents damage to, or improper shifting of the pavement restraint structure with respect to the pavement due to large changes in temperature of the structure.
