Title: Apparatus for and method of using optical interference of light propagating through an optical fiber loop
Inventor: NAKAMURA YASUSHI
IPC: G01H9/00
Filed: 1999-04-27
Granted: 2003-04-08
Abstract: A signal/vibration detecting technique employs a simple structure to identify a target optical fiber among many and carry out a bidirectional conversation through the target optical fiber.      First ends of optical fibers (202A, 202B), one of which is a target optical fiber, are connected to an optical transceiver (201). Second ends of the optical fibers are connected to each other to form a loop. A local unit (203) is installed at the loop. The local unit vibrates the loop, and the optical transceiver emits lights so that the lights are oppositely propagated through the loop. The propagated lights are coupled together so that they interfere with each other.      In the intensity of the interfering lights, a change corresponding to the vibration is detected to identify the target optical fiber. Once the target optical fiber is identified, it is used to carry out a conversation between the optical transceiver and the local unit.

Title: Novel method and apparatus for traffic shaping in a broadband fiber-based access system
Inventor: FISHER DAVID ANTHONY
IPC: H04L12/56
Filed: 1999-05-20
Granted: 2009-12-08
Abstract: A novel method and apparatus for controlling the flow of traffic between a host digital terminal (HDT) and a plurality of optical network units (ONUs). Each ONU is connected to the HDT by optical fiber and to a plurality of subscribers by a respective plurality of subscriber drops. The bandwidth on the fiber, although large, is usually inferior to the total bandwidth that can be transmitted across the subscriber drops. Therefore, both upstream and downstream traffic may become congested at various "choke points" under certain circumstances of usage. The present invention provides a traffic shaper located in the HDT, which gives centralized control of the traffic flowing to and from the ONUs. Consideration of the priority and destination of each traffic cell is taken into account by the traffic shaper to ensure that the capacity of the fiber and of the individual drops is never exceeded, irrespective of the transaction sizes, thereby eliminating the need for costly buffers in the outside plant. Any maintenance or repairs of the traffic shaper can be easily effected without field visits, due to its centralized location.
Patent CA-2273461-C (CA)
Title: Quick release and storage system based on an eccentric rotating element
Inventor: BOURGAULT GERARD F J
IPC: A01B15/18
Filed: 1999-06-02
Granted: 2007-08-07
Abstract: Disk coulters are used on numerous soil engaging farm implements to cut furrows into which seed or fertilizer can be deposited. Disk coulters may also be used to cover furrows or simply cut trenches in the land. Typically, an implement or tool bar frame may have several disk coulter assemblies attached to the frame. Some are dedicated to inserting seed into the soil and other fertilizer. In an alternate configuration, the implement or tool bar may have a combination of shanks and coulters. In any given application it may not be necessary to use some of the coulter disks assemblies. Because of the wear on coulters as they move through the soil and encounter rock and other debris, it is advantageous to be able to quickly lift some of the coulter disks out of the soil while operating with other disks. The present invention provides an eccentric rotating element attached to a spring which generally in operation exerts force upwardly on the coulter arm and therefore maintains the coulter in a downward position. By rotating this eccentric rotating element the spring may be released and the coulter disk raised, by hand, off the ground and thereafter locked in place with a spacer element. With the present invention the operator can easily lift or lower coulters in the midst of a seeding operation.

Title: Lighting fixture assembly sealed at opposite ends with dust covers
Inventor: BODELL STEVEN W
IPC: F21V15/00
Filed: 1999-05-31
Granted: 2006-08-01
Abstract: A lighting fixture assembly includes a lighting fixture having a mounting member, a pair of end plates, an elongated lamp and an elongated lens, and a pair of dust covers fittable over opposite ends of the lighting fixture. Each end plate is mounted to one of the opposite end of the mounting member and is substantially comprised of a first material having a first coefficient of thermal expansion. The lamp is mounted adjacent to the mounting member and extends between the end plates and has opposite ends disposed adjacent to the end plates. The lens is mounted adjacent to the mounting member and extends between the end plates and has opposite ends disposed adjacent to the end plates. The lens together with the mounting member and end plates substantially encloses the lamp. The lens is substantially comprised of a second material having a second coefficient of thermal expansion different from the first coefficient of thermal expansion of the first material of the end plates such that when the lens and end plates are heated during illumination of the lamp a difference in expansion of the second material of the lens and the first material of the end plates occurs creating gaps between the opposite ends of the lens and end plates. Each dust cover securably fits over one of the end plates, one of the opposite ends of the mounting member and one of the opposite ends of the lens for covering the gaps therebetween and thereby sealing the assembly at the locations of the gaps to prevent foreign matter from entering the assembly through the gaps.

Title: A method of and apparatus for selecting base stations to communicate with a remote station
Inventor: SOLIMAN SAMIR S
IPC: H04B7/26
Filed: 1998-07-21
Granted: 2008-07-15
Abstract: A mobile station (2), for use in a communication system compris-ing plural base stations (4) controlled by a base station controller (6), com-prises a receiver (50, 52, 54) for re-ceiving signals from plural base sta-tions which together comprise a set of candidate base stations. The mo-bile station determines power in the received signals, and compares the power with a first threshold value.  The mobile station (2) identifies base stations (4) whose signals have a re-ceived power greater than the first threshold value and transmits a sig-nal to the controller (6) representing identified base stations as being suit-able for inclusion in an active set.  The measured pilot energy of each pilot in the candidate set is iteratively compared against a threshold gener-ated in accordance with the sum of the energies of the pilots in the ac-tive set. If the strongest pilot in the candidate set satisfies this threshold condition, it is added to the revised active set. A second iterative process is performed to determine whether a pilot should be deleted from the revised active set. The mobile station (2) determines whether a change to the current active set is desirable by measuring the energies of the pilots in the active set and the candidate set, and dynamically adjusting the necessary thresholds based on its own estimation of the communication environment.
