Patent CA-2293001-A1 (CA)
Inventor: SCHMIDT PHILIP D
IPC: A61M5/32
Filed: 1999-12-21
Abstract: A solid blunt and a needle assembly having a solid blunt. The solid blunt helps to prevent accidental needle sticks. In one exemplary embodiment, a solid blunt has an outer dimension (e.g. outer diameter) which is nearly equal to an inner dimension (e.g. inner diameter) of a cannula of a needle which is configured to contain the solid blunt. In one example, the solid blunt substantially blocks fluid flow in a first circumferential portion of an inner diameter of the cannula and allows fluid flow in a second circumferential portion of the inner diameter. The solid blunt is typically capable of longitudinal movement through the cannula and is prevented from moving substantially in a direction perpendicular to the longitudinal movement. A needle assembly, in another exemplary embodiment, includes a solid blunt, a cannula and a clip which couples slidably the solid blunt to a frame which is coupled to the cannula. The present invention may be used with medical devices including needles, introducers and catheters and other devices as well.
Patent CA-2297235-A1 (CA)
Title: Wood chips analyser
Inventor: NADER JOSEPH
IPC: G01N33/46
Filed: 2000-01-26
Abstract: The present invention concerns a wood chips analyser. A sample of a load of chips is weighed, and then inserted into the analyser. A sifting drum sifts out any dust present in the sample. The chips are then spread out through the use of a spreader drum and two vibrating trays, which insure that the chips are oriented horizontally. The chips are then fed to a transparent conveyor. A pair of cameras are arranged about the conveyor, one camera facing each surface of the conveyor. The output of the cameras is sent to a controller, which makes a three-dimensional representation of each chip. Once the sample have been analysed, a report is generated according to modifiable criteria. A typical report will indicate the percentage of a category of chips. This information is then used by paper mills to treat the chips accordingly.

Title: Filtered exhaust engine
Inventor: BEAUDOIN NORMAND
IPC: F02B75/02
Filed: 2000-02-02
Abstract: When considering the main types of commercial engines available on the market, whether two-stroke, four-stroke or rotary-type, it is found that, and this is commonplace, said engines are highly polluting. The main reason for this lies in the difficulty to manufacture worn gas filters which would not induce restriction However, that difficulty can be overcome by producing an engine which is itself capable of sustaining a high rate of restriction. The technical solutions disclosed by the invention present several embodiments enabling the engine to tolerate a higher level of restriction and consequently a more dense filtering. These various technical embodiments provide for a novel path for fresh gases through the engine. The invention provides a solution, which is not primarily concerned with fresh gas supply but rather with waste gas absorption, followed by their subsequent evacuation constituting the first stroke of said engine. Indeed, the waste gases are evacuated outwards by two successive steps: the gases are evacuated outwards by pumping, and said discharge generates, in turn, a vacuum which sucks in the burnt fresh gases which in turn finally suck in the fresh gases. Said techniques have the further advantage of producing two stroke engines powered with gas only, and consequently cleaner and more efficient.

Title: System and method for intraluminal imaging
Inventor: WILLIAMS ALFRED E
IPC: A61B8/12
Filed: 1998-09-16
Abstract: A vascular catheter system (10) comprises a catheter body (18) having a proximal, a distal portion (40, 60), and a single common lumen therebetween. The catheter body includes a first connector (42) secured to the distal end of the proximal portion (40), and a second connector (44) secured to the proximal end of the distal portion (60). The connectors can be selectively connected to each other to join the lumens of the proximal, and distal portions together in a continuous, axially fixed relationship. Disposed within the lumens, when the proximal, and distal portions are joined together, is a drive cable (50).  The drive cable (50) may be movably rotatable about its own longitudinal axis, and carries at its distal end, a work element, which is typically an ultrasonic imaging transducer (56) or intervention device. The lumen carrying the cable will be sufficiently large along a proximal portion to permit preferential collapse of the cable should rotation of the distal end become impeded. The catheter body may be made of a polymer or plastic material, such as polyether ether ketone (PEEK), which provides adequate bonding stiffness, and resistance to kinking from large hoop stresses.

Title: A device for the rapid preparation of drinks in microwave oven by means of the intimate interaction between a heated fluid and a divided or porous substance
Inventor: CONVERTI MAURIZIO
IPC: A47J31/54
Filed: 2000-06-15
Abstract: A device for the rapid preparation of drinks in microwave oven by means of the intimate interaction between a heated fluid and a divided or porous substance comprises a first container, made of a material compatible with microwaves and transparent thereto, comprising a first compartment for containing a fluid in the liquid state, a second compartment for containing a divided or porous substance, a communication conduit between the first and the second compartment. An access way to the first and to the second compartment, with hermetically sealing closure, allows to insert the fluid in the liquid state and the divided or porous substance in the first container. The second compartment has a holed bottom to serve as a filter. The communication conduit has its inlet in the first compartment and its outlet in the second compartment and it allows the passage of the fluid from the first to the second compartment, when between the first and the second compartment a predetermined pressure differential is established as a result of the heating of the fluid by effect of the microwaves, allowing, by gravity and pressure, the subsequent traversing of the divided or porous substance by the fluid with the consequent production of a drink. The drink can be collected through the holed bottom of the second compartment in an underlying second container supporting the first container. [FIG. 5]

Title: Implementation of opportunistic data on a statistical multiplexing encoder
Inventor: WU SIU-WAI
IPC: H04J3/24
Filed: 2000-06-29
Abstract: A method and apparatus for providing an opportunistic data capability for an existing statistical multiplexing encoder platform, such as a multi-channel video data encoder. An Opportunistic Data Processor (ODP) is provided as a plug-in card or an external device that can be interfaced with an existing multi-channel encoder. The ODP communicates with a Quantization Level Processor (QLP) and Packet Multiplexer (PM) in the multi-channel encoder as if it was just another channel encoder. The ODP implements a special rate control scheme by encoding data and sending it to the PM only when a global Quantization Level (QL) indicates that spare bandwidth is available. Spare bandwidth is assumed to be available when the global QL is less than a threshold value. Moreover, the OPD sends a bandwidth need parameter to the QLP, as do the other channel encoders. However, the ODP's need parameter is scaled by a function of the global QL to attenuate its actual bandwidth need as the global QL increases to provide smooth variations in the ODP's encoded data rate.

Patent CA-2323284-A1 (CA)
Title: Led lighting fixture
Inventor: TAKEYASU MITSURU
IPC: F21S8/00
Filed: 2000-10-13
Abstract: The present invention relates to a light fixture that is comprised of several elliptical light distributing LEDs located in the center of a unit-type lens. One or more unit-type lens structures and their associated LEDs can be stacked to form the light fixture. The LEDs are arranged around the horizontal circumference in such a way that the wider divergence angle of each LED 1 is oriented horizontally. The unit-type lenses are stacked and fastened with a screw that runs through the bosses. The horizontal light distribution characteristics of the LEDs can be made nearly concentric with only a few LEDs, thereby making it possible to uniformly distribute light horizontally. It is also possible to make the lighting fixture lighter and smaller. By increasing or decreasing the number of unit-type lenses to be stacked, the number of tiers can be easily changed. By using such LEDs with an extremely wide horizontal divergence angle and a much narrower perpendicular divergence angle than those of conventional LEDs, lenses and the process for forming lenses become unnecessary, resulting in lower costs.
