Filed: 2001-02-02
Abstract: The present invention provides a system and method for reserving data channels in an optical burst-switched network. A data channel (or a multiple of data channels) along an optical path in an optical burst-switched network is reserved by first transmitting a data channel reservation request from an electronic ingress edge router to a reservation termination node. Next, the data channel reservation request is processed at all nodes along the optical path, including the reservation termination node. A data channel reservation acknowledgement is then transmitted from the reservation termination node to the electronic ingress edge router. Finally, the data channel path is reserved once an initial burst(s) which contains a reserve data channel bit reaches the reservation termination node.

Patent CA-2362792-A1 (CA)
Inventor: MCKINNON BRIAN W
IPC: A61F2/34
Filed: 2000-03-03
Abstract: An inserter (10) includes a frame (12) having a central bore through which a threaded rod (24) is inserted. The threaded rod (24) is inserted into an implant (40) to secure the inserter (10) to the implant (40). A thumbscrew (14) is located along a length of the rod (24) and is used by an operator to thread the rod (24) into the implant (40). A biasing member (30), which preferably comprises a set of spring washers (30), is located between the thumbscrew (14) and a slider (18). A lever (16) on the inserter has a cammed surface which forces the slider (18) toward the thumbscrew (14) when the lever (16) is closed. When the slider (18) moves closer to the thumbscrew (14), the spring washers (30) are compressed and generate opposing forces that are applied to the thumbscrew (14) and slider (18). These opposing forces are transferred to the rod and to the frame (12) of the inserter (10) and produce a resultant force that causes a compressive force to be exerted between the inserter (10) and the implant (40). This resultant force is intended to firmly seat the inserter (10) on the implant (40) and to reduce the possibility that any blows applied to the inserter (10) are diverted to the rod (24) causing the rod (24) to loosen or disengage. Thus, in operation, a surgeon or assistant places the threaded rod (24) within the implant (40) and tightens it with the thumbscrew (14). After the rod (24) has been hand-tightened, the lever (16) is raised so as to generate the resultant force that compresses the inserter (10) upon the implant (40).

Title: Single etalon optical wavelength reference device
Inventor: TAYEBATI PARVIZ
IPC: H01S5/0687
Filed: 2000-08-10
Abstract: A compact wavelength monitoring and control assembly (10) for a narrow band (i.e., laser) source (12) is provided comprising a narrow bandpass, wavelength selective transmission filter element (18), of Fabry-Perot etalon structure (18), through which two collimated beams from a laser source (12) are directed onto two closely spaced photodetectors (22, 20). For wavelength stabilization, the differential output of the two photodetectors (22, 20) is used in a feedback loop (28) to stabilize the wavelength of the laser source (12) to the desired wavelength. Through the dependence of the wavelength transmission of the Fabry-Perot etalon (18) on angle and physical parameters (i.e., refractive index and thickness), a wavelength variation of the source (12) is converted into a transmission loss, which is different for the two photodetectors (22, 20), so that the wavelength change is detected by changes in the signals output from the two detectors (22, 20).
