Title: Arrangement in a two cycle combustion engine with internal combustion
Inventor: HENRIKSEN LEIF DAG
IPC: F02B41/04
Filed: 1998-04-22
Abstract: A combustion engine (10) has a number of engine cylinders (21-1 - 21-5) arranged in an annular series around a common middle drive shaft (11) with the cylinder axes running parallel to the drive shaft. Each cylinder includes a pair of pistons (44, 45) movable towards and away from each other, which work in a common, intermediate working chamber (K). Each piston (44, 45) forms - via a piston rod (48, 49) with associated support roll (53) - support and control via a "sine" - plane ("sine" - curve (8a, 8b)) in a cam guide device. The two pistons (44, 45) in each cylinder (21; 21-1 - 21-5) have mutually differing piston phases, which are controlled by mutually differing cam guide devices. The cam guide devices are designed with equivalent mutually differing "sine" -planes ("sine" - curves (8a, 8b)).

Patent CA-2315167-A1 (CA)
Title: Improved aileron for fixed wing aircraft
Inventor: LAM MICHAEL
IPC: B64C9/06
Filed: 1998-12-03
Abstract: An aircraft aileron system (10, 10) is comprised of two panels (12, 14, 28, 30, 62, 70) located at the rear portion of the wing (W24, 54), in a spanwise direction and aligned with the wing's trailing edge. The panels are independently hinged at their leading edges and rotate to make angular deflections with respect to the wing. The upper, aileron panel (12, 30, 62) is restricted to upward deflection only from its neutral position and in operation is deployed independently as an aileron. The lower, auxiliary flap panel (14, 28, 70) is capable of both upward and downward deflections from its neutral position, and is deployed independently downward as an auxiliary flap. Both panels are deployed together upwardly only as an aileron. Alternatively, the auxiliary flap panel is capable of downward deployment only, to provide a simpler aileron system. For roll control of an aircraft during cruise, the aileron panel on one side only is deflected up while the aileron panel on the other side remains in its neutral position.

The sustained release microparticles are prepared through a multi-emulsion process.      A drug of interest is dissolved or dispersed in each of at least two oils to give at least two primary oil phases or emulsions. Each oil phase or emulsion contains a biodegradable polymer. The least two primary oil phases or emulsions are dispersed in one aqueous phase, synchronously or in succession. From the drug-dispersed solution, the organic solvents are removed to produce microparticles.      Therefore, the drugs such as leutenizing hormone releasing hormones can be continuously released in vivo for prolonged periods of time, bringing about an improvement in the therapeutic effect.
Patent CA-2317971-A1 (CA)
Inventor: DANTU RAM
IPC: H04L12/437
Filed: 2000-09-08
Abstract: An apparatus and a method for forwarding data packets through a fiber optic ring network includes forwarding data packets on a packet by packet basis. A node on the fiber optic ring network decides on a packet by packet basis whether to transmit on the working or protection path. Because this decision is being made on a packet level, reservation of throughput resources no longer is made at a one to one ratio.      Rather, protection path resources are reserved at a ratio significantly less than one to one. In one embodiment, no resources are reserved for path restoration or protection path routing. Rather, quality of service provisioning is used to resolve interference situations wherein instantaneous demand exceeds capacity. A node evaluates ring conditions in relation to the demand of traffic resources and the relative quality of service ratings to determine whether and how to forward a packet.      Additionally, a node decides whether to use the working or protection path by considering the final destination on the fiber optic ring network, any identified ring conditions and, in some embodiments, quality of service. The ring conditions to which the inventive nodes respond include OSI layer 1, layer 2 and layer 3 conditions. In alternate embodiments, the node also evaluates parameters such as identified or assigned quality of service parameters. Whenever a layer 1, a layer 2 or a layer 3 condition occurs, a node generates an overhead signal within fifteen milliseconds of the condition occurring. An ingress node (a node that receives IP traffic and places it onto the fiber optic ring network) is adapted to effectuate path restoration within 35 milliseconds of receiving the overhead signal identifying a failure and within fifty milliseconds of the failure condition event.

Title: Configurable optical add/drop device
Inventor: CAI BO
IPC: G02B6/293
Filed: 2000-03-21
Abstract: An add/drop device is described that allows channels from a multi-channel optical path to be dropped to a device and a new or modified channel to be added to the multi-channel optical path. The device thereby has access to a channel from the multi-channel optical path without having access to all of the channels. In one embodiment, the add/drop device of the invention includes one or more intermediate ports (330, 340) and a switch (360). The intermediate ports (330, 340) communicate the channels not dropped by the add/drop device and the switch (360) selectively optically couples the dropped channel either to the device or to be added back into the multi-channel path. The switch also selectively optically couples the new or modified channel to be added to the multi-channel path. The one or more intermediate ports (330, 340) allow multiple add/drop devices to be optically coupled together to provide a configurable add/drop mechanism.
Patent CA-2337172-A1 (CA)
Title: Method and apparatus for allocating functional units in a multithreaded vliw processor
Inventor: KAXIRAS STEFANOS
IPC: G06F9/38
Filed: 2001-03-01
Abstract: A method and apparatus are disclosed for allocating functional units in a multithreaded very large instruction word (VLIW) processor. The present invention combines the techniques of conventional VLIW architectures and conventional multithreaded architectures to reduce execution time within an individual program, as well as across a workload. The present invention utilizes a compiler to detect parallelism. The disclosed multithreaded VLIW architecture exploits program parallelism by issuing multiple instructions, in a similar manner to single threaded VLIW processors, from a single program sequencer, and also supports multiple program sequencers, as in simultaneous multithreading. Instructions are allocated to functional units to issue multiple VLIW instructions to multiple functional units in the same cycle. The allocation mechanism of the present invention occupies a pipeline stage just before arguments are dispatched to functional units. The allocate stage determines how to group the instructions together to maximize efficiency, by selecting appropriate instructions and assigning the instructions to the FUs. The criteria for selection are thread priority or resource availability or both. Under the thread priority criteria, different threads can have different priorities. The allocate stage selects and forwards the packets (or instructions from packets) for execution belonging to the thread with the highest priority according to the priority policy implemented.  Under the resource availability criteria, a packet (having up to K instructions) can be allocated only if the resources (functional units) required by the packet are available for the next cycle. Functional units report their availability to the allocate stage.
