Title: Variable dispersion compensator and optical transmission system
Inventor: SUGANUMA HIROSHI
IPC: H04B10/2513
Filed: 2002-04-02
Abstract: An optical signal, which is to become the subject of dispersion compensation, is split by optical combining/splitting unit 2, and each frequency component of the optical signal that is split is reflected by the corresponding reflective mirror 30 included in reflective mirror group 3 to apply a predetermined phase shift to the respective frequency components. Each reflected frequency component is then combined using optical combining/splitting unit 2, to give dispersion compensated optical signal.      Furthermore, in regards to reflective mirror group 3, which is used to apply phase shift to each frequency component of an optical signal, each of the respective plurality of reflective mirrors 30 is made a movable mirror having a movable reflection position that reflects the frequency components.      Through this, dispersion that develops in an optical signal may be compensated with favorable controllability and high accuracy. Therefore, the precision and controllability of dispersion compensation will become superior, and realized is a variable dispersion compensator having a miniaturized optical circuit, and an optical transmission system comprising such variable dispersion compensator.

Abstract: A system and method for severing a portion of a wrapping film for facilitating the detachment and attachment of trailing and leading end portions of the wrapping film from and onto loads disposed at a wrapping station in con-junction with film wrapping operations being performed upon loads being wrapped at a wrapping station comprises an actu-ating arm movable between retracted and extended positions and upon which a fixed clamping member and a movable clamp-ing member are mounted such that the movable clamping member can move toward and away from the fixed clamping member so as to define therewith CLOSED and OPENED positions. Upon termination of a wrapping operation, the actuating arm is moved from its retracted position to its extended position, the clamping members are moved to their CLOSED position so as to clamp a portion of the wrapping film therebetween, and a hot-wire cutter is energized so as to sever a portion of the clamped film. A trailing end portion of the wrapping film is thus released for self-adherence to the wrapped load, while a leading end portion of the wrapping film is maintained clamped between the clamping members in prepara-tion for self-adherence to a new load to be wrapped. When wrapping of the new load is commenced, the movable clamping member is moved to its OPENED position such that the clamped leading end portion of the wrapping film is released for self-adherence to the new load to be wrapped, and the actu-ating arm is returned to its retracted position.

Patent CA-2393509-A1 (CA)
Inventor: SIH GILBERT C
IPC: H04B1/7093
Filed: 2000-12-20
Abstract: A novel and improved method and apparatus for searching is described. This searcher combines the ability to search multiple offsets of single pilots, such as those found in the IS-95 system, with the ability to search multiple pilots, such as those found in a GPS location determination system. Both types of searching can be done in a single architecture combining the parallel computation features of a matched filter with the flexibility of allowing a variable number of non-coherant accumulations to be performed at high speed for a wide range of search hypotheses in a resource efficient manner. This invention allows for parallel use of the matched filter structure in a time-sliced manner to search multiple windows. In addition, the searcher allows for optional independent Walsh decovering for each search window. The time-sharing approach allows for optional frequency searching of any offset.

IPC: A61F2/00

Abstract: An intraocular lens implantable in an eye includes an optic for placement in  the capsular bag of the eye and for directing light toward the retina of the  eye. The optic has a central optical axis, an anterior face, an opposing posterior face and a peripheral edge between the faces. The peripheral edge has one or more curved or angled surfaces that reduce glare within the IOL. For instance, a rounded transition surface on the anterior side of the peripheral edge diffuses the intensity of reflected light, or a particular arrangement of straight edge surfaces refracts the light so as not to reflec t, or does not reflect at all. The intersection of the peripheral edge and at least one of the anterior face and the posterior face, preferably both of su ch faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces. The present IOLs inhibit  cell growth from the eye in front of or in back of the optic and reduce glar e obtained in the eye in which the IOL is located.

Title: Hub seal firestop device
Inventor: CORNWALL KENNETH R
IPC: F16L55/10
Filed: 2002-11-19
Abstract: A firestop device (10) and firestop assembly for use in a plumbing system (100) installed in a structure to prevent the transmission of smoke and fire through the plumbing system. The firestop device includes a housing (12) with a connector (14) and intumescent material (16) mounted in the inner passageway (12C) of the housing. The firestop device is intended to be mounted over the hub portion (50B) of a plumbing fitting (50). When the housing is heated, the heat is transferred to the intumescent material which expands. As the intumescent material expands, the material crushes the conduit (102) extending through the firestop device and completely blocks the inner passageway (10C) of the firestop device which prevents smoke and fire from moving through the firestop device.

IPC: B29C33/02
Filed: 2002-12-12
Abstract: Apparatus and method for molding a tire (110) with a radially expandable bead molding ring (252). When expanded, the bead molding ring has a circumferentially continuous radially outward-facing surface (259) for molding the bead. The bead molding ring comprises a plurality of segments (254, 256), half of the segments being first segments (254) that are complementary to, and circumferentially alternated with second segments (256).  The first segments are wedge shaped, having circumferentially lateral faces (255) that converge towards the radially outward-facing bead molding surface of the bead molding ring, the first segment lateral faces being planar and oriented in the axial direction; and the second segments have lateral faces (257) that are complementary to the first segment lateral faces, such that radially outward movement of the first segments (254) causes radially outward movement of the second segments (256). Guide rods (260) restrict first and second segments to radial movement (310) only. The elements of the bead molding ring are preferably combined in a single assembly (280) with the sidewall mold to form a unit that is easily maintained and changed to adapt to different profiles to be molded on beads of different tire constructions.   Expansion of the bead molding ring can be driven by a simple wedging action caused by a single frustraconical cam 266.
