Patent CA-2251555-A1 (CA)
Inventor: KOSCHMANN ERIC
IPC: A61B18/12
Filed: 1997-04-04
Abstract: A long pulse alexandrite laser for treating dermatological specimens is disclosed. The use of alexandrite allows operation in the near-infrared, specifically in a 50 nm range surrounding 755. Infrared in this range allows good penetration while still achieving an acceptable ratio of hemoglobin to melanin absorption. In operation, the laser generates pulses having a durations between 5 and 100 msec and fluences between 10 and 50 J/cm2. A light delivery system is provided that transmits the laser light output pulse to dermatological targets of a patient. The invention is also directed to a hair removal system. Here, it is desirable to use an index-matching application on the skin sections to be treated, and a visual indicator is thermo- or photo-responsive or otherwise responsive to the laser light pulse to generate a visible change. This provides the operator with a record of those parts of the skin that have already been treated. Finally, the invention is directed to a combined sclerotherapy and light treatment method and kit for unwanted veins.  Substantially increased success, in the range of 90-100 % has been achieved by implementing a dwell time of between 12 hours and 6 months between the light-based therapy and the sclerotherapy. Preferably, the light-based therapy is performed before the sclerotherapy. Success can be achieved by performing the sclerotherapy followed by the light-based therapy after the dwell time, however.

Title: Disposable absorbent garment and method of constructing the same
Inventor: JOHNSON LARRY KENNETH
IPC: A61F13/15
Filed: 1997-09-22
Abstract: A disposable, absorbent garment, such as a diaper, having an absorbent core (14) and stretchable, substantially liquid impermeable web (12). The core (14) is attached to the web (12) by a strip of adhesive (32) extending in a longitudinal direction along the bottom surface of the core (14). The web (12) is folded around the exterior of the core (14) and includes notches formed in opposing sides of the crotch portion of the web (12). When folded about the core (14), the notched areas form a longitudinally extending opening along the top surface of the core (14). A plurality of elastic bands are affixed along the crotch portion of the web (12) so as to extend substantially parallel to, but inwardly of the notched areas. The elastic bands constrict the web (12) adjacent the notches to form cuffs which fit snugly about the wearer's legs. Adhesive tabs, or another similar closure device, is attached on opposite sides of the web (12) to hold the garment together about the wearer's torso. Alternatively, opposing sides of the garment may be sealed together to form a pant. Elastomeric material is affixed to strategic positions of the web (12) to increase the elastic force of the web (12) when stretched, to enable the garment to better conform to the wearer's body. Optionally, heat shrinkable film may be disposed about the opening formed by the notches in order to raise the edges of the opening and form a pocket for containing solid waste materials.

Title: Method and apparatus for tracking call history for mobile and wireline users accessing the network on different ports for subsequent calls
Inventor: THOMPSON JANE ANN
IPC: H04Q3/00
Filed: 1999-05-04
Abstract: This invention provides a method and apparatus for associating call data with particular users instead of line ports. This call data includes the last incoming and outgoing calls associated with a particular number. This allows the services such as automatic callback, automatic recall, and customer originated trace to be implemented with dynamic line assignment allowing users to maintain the same level of subscribed services at different locations. For mobile users, automatic callback, automatic recall, and customer originated trace can be implemented at the home mobile switching center as well as roaming mobile switching centers. If the mobile user is roaming, updating the call history of the mobile station at the new mobile switching center allows the mobile user to experience seamless services across a large territory.

Patent CA-2279449-A1 (CA)
Title: Adjustable bobber system
Inventor: MOSHER BRUCE
IPC: A01K93/00
Filed: 1999-07-30
Abstract: An adjustable bobber system for allowing adjustment of the buoyancy and for attaching to a fishing line without the use of a bead. The inventive device includes a hook member connected to a buoyant member. The hook member includes a body with an open end that receives the buoyant member, a jaw extending from the body with a slot within, and a slit extending into the jaw to the slot for receiving the fishing line below a stop knot. The buoyant member is preferably constructed of an elongated buoyant material, such as plastic foam, that is easily severed in any position by a cutting device. The user first ties the stop knot along the fishing line in the desired location. The user then simply engages the hook member upon the fishing line below the stop knot. If the user desires less remaining buoyancy, the user simply removes a portion of the buoyant member with a conventional cutting device, such as a scissors. A marker band is preferably adjustably positioned about the buoyant member for providing a visible mark upon the buoyant member that is a finite distance above the water level when the fishing lure and/or bait are attached. If the fish engages the bait and pulls the buoyant member downwardly, the marker band will become submerged informing the fisherman that a fish is present. Because the hook member remains in contact with the fishing line at all times beneath the water surface, there is not freezing of the fishing line to the hook member. In addition, any ice buildup upon the buoyant member can be easily removed by simply squeezing or bending the buoyant member without breaking or damaging the buoyant member.

Inventor: ROFEN ROBERT R
IPC: A01K63/10
Filed: 1999-08-17
Abstract: An apparatus for cleaning the inner wall surfaces of an aquarium tank includes a pair of magnetic assemblies adapted for mutual magnetic engagement.  Both assemblies include an outer housing of waterproof material, and a planar surface adapted to impinge on the aquarium walls. A scrubber pad is laminated to at least one planar surface of the assemblies, and a strong permanent magnet is secured within the protective enclosure of each housing. One assembly impinges its scrubber surface on the inner surface of an aquarium wall, and the other assembly is disposed directly adjacent to the inner assembly and in magnetic engagement therewith. Translating movement of the outer assembly causes concomitant movement of the inner assembly, whereby the scrubber surface of the inner assembly is translated across the inner surface of the aquarium wall for cleaning purposes. A float is secured by a line or cord to the magnetic assembly disposed within the aquarium. If the inner assembly disengages from the outer assembly, and falls to the bottom of the aquarium, the float will remain at the surface of the water in the aquarium, and the inner assembly may be retrieved by grasping the float and pulling the line and inner assembly from the water. The float permits the inner assembly to be retrieved without requiring any exposure of the hands or clothing to the aquarium water, and with minimal disturbance to the fish within the aquarium.
