Patent CA-2275913-A1 (CA)
Inventor: SOLHEIM ALAN G
IPC: H04J14/02
Filed: 1999-06-22
Abstract: The present invention provides a method of and system for carrying bidirectional traffic on a ring transmission system, such as a SONET, SDH or WDM ring, on a single fiber. Using the present invention, hub and mesh traffic patterns can be implemented on a single fiber ring network in configurations such as a UPSR, a BLSR and a diversely routed 1+1 protection system. This allows for network startup with a substantially lower capital outlay than is associated with traditional ring transmission system configurations. In addition, the present invention greatly improves the efficiency of ring network utilization. Specifically, the present invention provides a method of carrying bidirectional traffic with protection in a ring transmission system on a single fiber. This method involves: transmitting working traffic over a first ring path from a first node to a second node in a first wavelength channel of the single fiber, transmitting working traffic over the first ring path from the second node to the first node in a second wavelength channel of the single fiber, transmitting protection traffic over a second ring path from the first node to the second node in the second wavelength channel of the single fiber and transmitting protection traffic over the second ring path from the second node to the first node in the first wavelength channel of the single fiber.

Title: Video reproducing apparatus with adjusted media change times
Inventor: NISHIDA YOSHIHIRO
IPC: H04N21/2315
Filed: 1999-08-06
Abstract: A video reproducing apparatus that stores video programs on multiple removable media, automatically changes the removable media, and supplies requested video programs to multiple terminal devices has a control unit that stores predicted times at which the programs currently being reproduced will require a change of removable media. When a program request is received, the control unit calculates the media change times of the program, and adjusts these times according to the stored predicted times. The adjustments enable all terminals to receive video programs without noise or interruption when the removable media are changed.

Abstract: A determination whether to establish a new connection that will supply new variable bit rate data packets to be transmitted in a shared system for transmitting variable bit rate data packets is made by determining, for the new connection, a value of a moment generating function defined based on the number of possible data packet sizes for the new connection, (Ri, Pi) pairs representing possible new connection data packet sizes, Ri, with corresponding assigned probabilities, Pi, and .theta. is an arbitrary positive real number.  A determination is then made whether any value of .theta. exists that satisfies the Chernoff bound for all established connections and the new connection, given a length of a buffer for storing data packets supplied to the shared system for transmitting variable bit rate data packets, and a predefined packet loss rate that can be tolerated in the shared system for transmitting variable bit rate data packets. If a value of .theta. exists that satisfies the Chernoff bound, then the new connection is established, else it is rejected. In another aspect, a maximum number of connections in the shared system is determined, given a transmission rate of the shared system.

Title: Migration of subscriber data between home location registers of a telecommunications system
Inventor: SUGIRTHARAJ DAVID
IPC: H04W8/12
Filed: 1998-10-30
Abstract: A common channel signaling system interconnects two home location registers. A data administrator responds to a network operator request by sending commands to a first (originating) home location register to have subscriber data extracted and formatted for communication over the common channel signaling system. Prior to communication, the first home location register verifies a common channel signaling system functionality level of a second (destination) home location register. If verified, the communication is sent, unformatted, and the included subscriber data stored. A data network and service management access layer further interconnects the two home locations registers. The data administrator responds to a generic network operator migration request by generating home location register specific commands instructing the first home location register to extract subscriber data for transfer over the data network and through the service management access layer to the second home location register for storage. Transfer considerations are also evaluated to select either the common channel signaling system or data network for the migration.

Title: Multi-thread re-entrant marker with transverse-anisotropy flux concentrators
Inventor: HO WING
IPC: C21D1/04
Filed: 1998-11-09
Abstract: A marker (20) for a harmonic electronic article surveillance system includes three wires (21) of magnetic material arranged in parallel. The material has a magnetic hysteresis loop with a large Barkhausen discontinuity such that, upon exposure of the marker (20) to an external magnetic field whose field strength in the direction opposing the instantaneous magnetic polarization of the marker exceeds a predetermined threshold value, there results a regenerative reversal of the magnetic polarization in the material. The three wires (21) are coupled at opposite ends thereof by flux concentrating elements (22, 23) formed of a highly permeable material so that all three wires exhibit the regenerative reversal simultaneously on exposure to the above-described magnetic field. The flux concentrators have magnetic anisotropies oriented transversely relative to the length of the wires to aid in coupling the wires for simultaneous switching.

IPC: G02B6/12
Filed: 2000-06-30
Abstract: Transmission characteristics of an optical device [200], fabricated from multiple layers [16, 27, 28] of silica-based glass on a silicon substrate [26], are modified by localized thermal treatment. The beam [501] of a carbon-dioxide (CO2) laser [510] is used to selectively soften the core and/or cladding material of a waveguide structure during or after the fabrication process. In one application, softening relieves the strain developed between the waveguide structure and the silicon substrate and substantially reduces or eliminates birefringence. In a second application, the CO2 laser is operated at another power level in order to modify the index of refraction. Changes in the index of refraction change the speed of light through a waveguide thereby changing the phase shift associated with the waveguide. In a third application, the CO2 laser is operated at yet another power level to increase the transmission loss of the waveguide. In all of the embodiments, heat treatment is substantially faster and/or less expensive than known techniques for modifying the transmission characteristics of an optical device.
