Patent CA-2384129-C (CA)
Inventor: LEE WHAY CHIOU
IPC: H04L12/56

Granted: 2006-06-13
Abstract: The problem of allocating bandwidth on the upstream channel (26) of an HFC  cable network (10) for contention-based transmission of requests that are used to reserve upstream bandwidth (26) for transmission of user data is solved by a method of allocation which dynamically adapts to the prevailing offered load of reservation requests. In one embodiment this is done by determining an appropriate size for a contention interval in each upstream transmission frame by attempting to balance the rates of flow of user data into and out of a virtual global data queue using a fluid approximation method that is based on a solution to a balanced equation relating the demand and supply of slots for data transmission within each frame.

Title: A cylindrical reactor with an extended focal region
Inventor: DROZD MICHAEL J
IPC: H05B6/80
Filed: 2000-12-07
Granted: 2009-12-29
Abstract: An elliptical exposure chamber has an extended focal region. A plurality of cylindrical reactors (25) form the ex-tended focal region. Reducing the size of the opening (58) to each reacto r (25) reduces the amount of energy reflected and increases the overall heating. In order to efficiently deliver the electromagnetic energy to the reduced opening (58), a tapered waveguide (55) has a concave end (56). A power splitter (42) divides power from a central waveguide (52) to the plurality of reactors (25). The power that is delivered to each reactor (25) can be adjusted by adjusting th e impedance of each reactor (25), the width of each reactor (25) or the width of the opening (58) to each reactor (25). The width of the opening (58) to each reactor (25) can be controlled by a movable metal plate (44). A dielectric wheel can be used to shift hot spots along the focal region.

Abstract: A shock absorber assembly includes a damping adjustment mechanism that can easily be incorporated into a twin cylinder design. The shock absorber includes an outer cylinder and an inner cylinder mounted within the outer cylinder. The inner cylinder is spaced apart from the outer cylinder to define a gap. A piston is mounted within a fluid filled chamber formed within the inner cylinder to dampen vibrations. Holes are drilled into the wall of the inner cylinder to provide fluid ports that can communicate with the gap to form a bi-directional fluid path as the piston moves back and forth within the chamber to dampen vibrations. To provide variable damping, the outer cylinder includes an eccentric inner diameter to outer diameter profile that allows damping adjustment between high and low damping forces. The damping force is adjusted by rotating the outer cylinder relative to the inner cylinder to vary the size of the gap with respect to the ports.

Abstract: A semiconductor laser device comprises a laminate consisting of a semiconductor layer of first conductivity type, an active layer and a semiconductor layer of second conductivity type different from the first conductivity type. The two semiconductor layers and the active layer are stacked with a waveguide region formed to guide a light beam perpendicular to the width by restricting the light from spreading in the direction of width in the active layer. The waveguide region has first and second waveguide regions. The first waveguide region is a region where light is confined within the limited active layer by a difference in the refractive index between the active layer and the regions on both sides of the active layer by limiting the width of the active layer. The second waveguide region is a region where the light is confined by providing effective difference in refractive index in the active layer.

Title: Prefabricated rail panel for use in mine shaft railway systems
Inventor: BERTRAND MORRIS P
IPC: E01B9/38
Filed: 2003-09-18
Granted: 2011-03-22
Abstract: A prefabricated rail panel for use in mine shaft railways includes a pair of conventional steel rails, a number of wooden sleepers and a series of rail mounting assemblies for coupling the rails to the sleepers. The rails are characterized by an upper rail surface and an enlarged laterally extending lower flange. Within the panel, the sleepers are arranged parallel to each other and transverse to the direction of longitudinal elongation of the rails. A rail mounting assembly is used to secure each selected one of the rails to an associated sleeper. The mounting plate assembly includes a rail fastening plate formed having a metal base plate portion and a pair of anchoring flanges. The anchoring flanges extend upwardly from an upper surface of the base plate in a generally mirror arrangement and define a longitudinally extending aperture extending between the flange and the upper surface of the base plate. Anchor clips are insertable in each longitudinal aperture to secure a selected rail to the rail fastening plate. A series of bore holes are formed through the base plate at spaced locations. Threaded fasteners are inserted through the bore holes and into threaded engagement with the sleeper, to thus secure the base plate in place. The threaded fasteners have a size selected to provide the rail panel with sufficient longitudinal stability, whereby the rails do not significantly deflect longitudinally and/or laterally relative to each other if the panel is suspended vertically as it is lowered down a mine shaft.
