Patent CA-2336493-A1 (CA)
Inventor: MOLLENAUER LINN FREDERICK
IPC: G02B6/02
Filed: 2001-03-01
Abstract: By urging an ordinary single-mode (usually dispersion-shifted) fiber into an external, long-period mechanical grating, a highly wavelength-selective coupling between the fiber's guiding mode and a cladding mode is induced. A sequence of such induced gratings, all on the same fiber, can be used to create a many tens of nm wide loss band of arbitrary shape, with resolution of 3 nm or better, whose strength at any wavelength can be continuously adjusted from zero to -17 dB or more. With its simplicity, nearly zero background loss, and especially, with its potential for continual readjustment, the device is ideal for dynamic gain equalization of optical amplifiers.

Title: Novel method of regulating seed development in plants and genetic sequences therefor
Inventor: KOLTUNOW ANNA MARIA GRAZYNA
IPC: C12N15/29
Filed: 1999-09-21
Abstract: The present invention provides a method of inducing seed development in plants, preferably in the absence of sexual fertilisation, said method comprising inhibiting or preventing the expression of one or more regulatory polypeptides that otherwise prevent asexual seed development in plants. The invention further provides novel genetic sequences (that is FIS1, FIS2, FIS3).  The invention further provides transformed plants having a wide range of novel phenotypes including, but not limited to, the ability to reproduce asexually, develop seed in the absence of fertilization, and the ability to produce parthenocarpic fruit or seedless fruit or fruits with soft seed traces such that the fruit are marketable as less seedy than wild-type fruit or seedless.  The isolated nucleic acid molecules are further useful in the detection of proteins and genetic sequences which interact with the polypeptides encoded by said nucleic acid molecules in the regulation of seed development in plants.

Abstract: A dissector/retractor device (10) comprising a balloon (12) having a deflated state, and an inflated state, is described for performing minimally invasive surgical procedures by creating a tunnel alongside a target tissue in the body. The balloon (12) in its inflated state forms an open space (16) extending transversely through the balloon (12). The balloon (12) is carried by an insertion assembly (14). The balloon (12) may be an elongate torus shape with an elongate open area in its interior. The insertion assembly includes a blunt dissection device, and a handle (22). In use, the dissector/retractor is inserted through a small incision, and bluntly tunneled (10) through body tissue to a desired location. The balloon (12) is inflated to create a space in the body tissue, and may also dissect tissue as necessary away from the tissue to be treated. The balloon (12) is left in place inflated to retract the space. Another incision may be made to provide more direct access to the target tissue than the original incision. The target tissue may then be diagnosed and/or treated through the direct access incision, through the overlying tissue, through the open space (16) in the balloon (12).

Title: Method and system for maintaining reserve command relationships in a fibre channel network
Inventor: REYNOLDS ROBERT A
IPC: H04L12/56
Filed: 2000-02-18
Abstract: A method and system for maintaining a unique reserve command relationship between an initiator (14) and a target device (16) in a Fibre Channel network (10) across network address changes after a break in communication. The present invention maintains triplet tables (18) containing data triplets, comprised of the network address, the port name, and the node name, for each initiator and each target device. Following a break in network communication that results in the network address of an initiator and/or a target device changing, the method of the present invention updates the recorded network addresses for the initiators and the target devices, maintains any previously-existing unique reserve command relationships and continues with I/O  transmission. Although the network address of an initiator may change, the node name and port name of the initiator will remain the same. By comparing the initiator port name and node name contained in a reserve table maintained in the target device to the node name and port name corresponding to the now updated network address for an initiator with which it was in a unique reserve command relationship prior to the break in communication, a target device can then simply update the network address for the initiator and no disruption in I/O traffic will result.
