Patent CA-2257764-A1 (CA)
Inventor: LU XIAOLIN
IPC: H04B10/272
Filed: 1999-01-07
Abstract: The present invention comprises a method and apparatus for delivering bi-directional broadband communications over an existing network. The present invention is particularly applicable in any existing network whereby multiple primary remote nodes (PRNs) are allocated along a communication path, which partition the communication path into multiple segments. Typically, the overall system bandwidth is defined/limited by the bandwidth of those PRNs, but the communication path itself has a much larger bandwidth. Through the introduction of secondary remote nodes (SRNs), the present invention provides a cost effective mechanism for providing bi-directional broadband communications in any communications network.

Title: Optical variable-ratio power splitter
Inventor: MACDONALD IAN
IPC: G02F1/313
Filed: 1999-01-11
Abstract: A variable-ratio optical sputter for dividing a beam of light launched into an input arm of a Mach-Zehnder interferometer into a plurality of sub-beams, each sub-beam having a predetermined intensity is disclosed. A transfer matrix is used to derive analytical expressions for an intensity distribution at the output ports of an integrated optical N x N generalized Mach-Zehnder interferometer. The analytical expressions for the intensity distribution are a function of one or more phase shifts applied to linking arms of two multimode interference couplers that form the Mach-Zehnder interferometer. These expressions form a system of nonlinear equations that are numerically solved for the phase shifts required, to achieve a specified intensity distribution for variable-ratio power splitting.

Title: Optical fiber amplifier surge protective apparatus
Inventor: NAKAMURA KEIJI
IPC: H04B10/07
Filed: 1999-01-13
Abstract: An optical fiber amplifier surge protective apparatus includes an optical branch unit, an optical delay circuit, a light input hit detecting circuit, a compensation optical signal generating circuit, and an optical multiplexer. The optical branch unit branches an optical signal input from an optical fiber line into a main optical signal on a main optical path and a branch optical signal on a branch optical path. The optical delay circuit delays the main optical signal on the main optical path. The light input hit detecting circuit monitors the level of the branch optical signal on the branch optical path to detect an optical fiber line hit. The compensation optical signal generating circuit generates a compensation optical signal having a wavelength different from that of the optical signal input when the light input hit detecting circuit detects the optical fiber line hit. The optical multiplexer multiplexes the compensation optical signal from the compensation optical signal generating circuit and the delayed main optical signal from the optical delay circuit.

Title: Sheet for protecting paint films of automobiles
Inventor: INOUE TSUYOSHI
IPC: C09J7/29
Filed: 1999-09-27
Abstract: A sheet for protecting paint films of automobiles which can prevent the paint film of automobiles from suffering from damages such as discoloration and denaturation even if rainwater or washer penetrates into the gap between the adhesive cover and the paint film while achieving excellent protection function to suspended matters, colliding matters, etc. inherent to protecting sheets and being easily peeled off and removed after completion of the desired protection. The sheet for protecting paint films of automobiles comprises a pressure--sensitive adhesive layer having a roughened surface provided on a substrate made of fiber sheet. Even when rainwater, washer, etc. penetrates into the gap between the pressure-sensitive adhesive layer and the paint film of automobiles from wrinkles formed thereon, the liquid diffuses by capillary action through the gap developed by the roughened pressure-sensitive adhesive layer, making it possible to avoid the residence and concentration of the penetrated dirty water and hence prevent the occurrence of damages such as discoloration and denaturation of the paint film. Further, the arrangement of a pressure-sensitive adhesive layer having a roughened surface reflecting the fiber constituting the protecting sheet, particularly a fibrous continuous roughened surface, makes it possible to further diffuse the contaminating dirty water and hence further avoid the retention and concentration of the penetrated dirty water. Thus, the damages on the paint film can be more securely prevented.
