Patent CA-2295794-A1 (CA)
Inventor: NGUYEN ANNIE THANHVAN
IPC: H04Q11/04
Filed: 1998-06-24
Abstract: Multimedia multipoint conferencing and distance learning sessions utilizing the ATM network (140) use multimedia conferencing equipment at remote sites coupled to the ATM network via ATM network interface switches (160NIb-e). All ATM switches (160) are coupled to, and receive control information from a network manager NM (130). An application server AS (120) is coupled to the NM, and is also coupled to conferencing equipment via an out-of-band connection such as ETHERNET, to which the conferencing equipment is also connected. To establish multimedia multipoint conference, the AS sends information regarding the participants to the NM. At conference time, the NM establishes a plurality of SPVC multicast trees from each participating site to all other participating sites in the conference, and activates one multicast tree and deactivates all others. An application running on a computer system at a main site (110a) tracks requests from remote sites (110b, c, d) for recognition. A request is recognized via a command sent from the main site to the AS which causes the NM to deactivate the previously activated multicast tree, and activate the already set up, but non-activated multicast tree from the recognized site to the main and other sites. Control is re-obtained by the main site by sending another command to the AS which causes the NM to deactivate the then active multicast tree and to reactivate the previous multicast tree from the main site to all remotes sites.

Title: The doggie takeout
Inventor: MORRISSEY PAUL
IPC: A01K7/00
Filed: 2000-10-19
Abstract: When owners or guardians of dogs take their animals out for a walk they must remember to take along some sort of bag to retrieve any dog waste. Also, most especially on warm or hot days dogs will always be on the lookout for a drink of water. When the temperature reaches a certain level any canine creature wearing a fur coat will begin to dehydrate, almost upon leaving their own doorway. Such necessities as described above are everyday occurrences and can be verified by dog owners. In order to combat some of these occurrences, the new and innovative "Doggie Takeout" is an answer to many of these daily problems. "The Doggie Takeout" is a light and durable container that will carry out a multitude of purposes. Made of plastic, this apparatus has six basic functions in one. A built-in retractable leash at the top of the hand held unit is a convenience in controlling the dog by its owner. Secondly, a screw-on bowl allows the owner to unscrew a water tight opening and thus pour water into the bowl for drinking water for the dog. This can be up to four full bowls of water. Thirdly, two separate compartments on one side of "The Doggie Takeout"  allows for the user to open the built in door frames. In one compartment are refillable baggies for dog excrement. In the next separate compartment is a space allotted for treats, such as small biscuits or snack food for the dog. On the opposite side of "The Doggie Takeout" is a fully enclosed moulded compartment for storing the excrement. This area will be thoroughly sealed in order to eliminate odor. The bottom inner half or more of the container will be filled with water up to and possibly more than a full litre. "The Doggie Takeout" will allow the dog owner to have all of the necessary elements for dog necessities in a convenient and stylish container which is light to carry even with the water inside. On a daily basis one can observe dog owners walking their dogs carrying supermarket bags and other containers because most communities have mandatory bylaws for dog droppings and, of course, there is the hygienic factor involved. With the new and innovative "Doggie Takeout" there should be less frustration and embarrassment for dog owners in general.

Title: Chiral twist laser and filter apparatus and method
Inventor: KOPP VICTOR IL ICH
IPC: H01S3/213
Filed: 2000-02-04
Abstract: A defect causing a localized state is induced in a chiral structure (12) composed of multiple chiral elements (20, 22) by twisting one element of the chiral structure with respect to the other elements along a common longitudinal axis such that directors of the element molecular layers that are in contact with one another at contact area (26) are disposed at a particular "twist" angle therebetween, the twist angle being greater than a shift angle between directors of consecutive layers. The chiral twist structure may be utilized in a variety of applications such as filters, lasers and detectors. The defect caused by the twist may be made tunable by providing a tuning device for rotating one or more of the chiral elements with respect to one another to vary the twist angle and thus vary the position of the induced defect within a photonic stop band. Tunable defects may be advantageously utilized to construct tunable wavelength chiral filters, detectors and lasers.

Title: Multi-valve injection/aspiration manifold
Inventor: WERSCHMIDT GARY S
IPC: A61M39/02
Filed: 1999-06-18
Abstract: A IV manifold (18) includes a plurality of injection/aspiration ports (27, 30, 32), and has an elongate configuration with a width greater than the diameter of the ports. A flow channel (49) is formed between mating members (22, 24) of a housing (23) and provided with a U-shaped configuration (90). Projections (50, 52, 54) along the flow channel direct fluid flow into valve cavities (63, 65, 67) associated with the ports to clear dead spots around the valve elements (30, 32, 34). A check valve (26) included in the manifold tends to create direct high-pressure against the valve elements which respond by forming a surface seal thereby avoiding deformation. An aspiration port can be formed with a second seal disposed on the side of the valve element opposite the first seal. Opening this second seal by negative pressure in the lumen of the port provides for the aspiration of fluids in the flow channel. Two-way aspiration can be provided by a valve having a cage with or without compressible characteristics to accommodate low tolerance fittings.
