Patent CA-2210723-A1 (CA)
Title: Positioning system
Inventor: EKSTR M TOMMY
IPC: G01S5/14
Filed: 1996-02-16
Abstract: The invention relates to a method and to a system for frequently determining the position of a mobile station (40) in a cellular mobile telephone system, particularly a GSM system. The position of a mobile station in the system is determined by carrying out a simulated call setup, i.e., the call setup is interrupted subsequent to a telephone switching centre (MSC) having received a paging response containing the identity of the cell and optionally timing advance. In one embodiment of the invention, a mobile station (40) is also commanded to connect itself to base stations (44) contained in its neighbour list, whereafter the mobile station sends position determining parameters to a position handler (14), the goegraphical position of the base station is analyzed from the cell identity and the optional timing advance. The position of the mobile station is presented graphically on a picture screen and is updated constantly after each call setup. The call setups are generated by the position handler (14).

Title: Method and apparatus for lenticular liquefaction and aspiration
Inventor: ANDREW MARK
IPC: A61F9/007
Filed: 1995-12-18
Abstract: A technique is described for liquefying, or gelifying, a hardened, cataractous lens nucleus and aspirating the same. Heat or heated solution is delivered to the lens nucleus in vivo so that the heat or heated solution is placed in contact with the hardened nucleus in order to heat and liquefy the same. The lens nucleus is irrigated simultaneously with a cooled solution to thereby limit to a very small area where the heat or heated solution is present in the eye. This allows the surgeon precise control over which intraocular anterior segment structures are exposed to the heat or heated solution. The liquefied lens nuclear material is then aspirated from the eye. The above allows the removal of a lens nucleus through a 1 to 2 mm corneal or limbal incision which is smaller than the smallest incision allowable with previously known small incision cataract techniques. The above benefits the patient as it allows small incision cataract removal to be done in a way that is non-traumatic to intraocular structures. The above benefits the surgeon, and the patient, in that it is a relatively straightforward and easy surgical maneuver for the surgeon to perform. This is in stark contrast to current phacoemulsification, which is potentially very traumatic to intraocular structures, and which is a relatively difficult surgical maneuver to perform.

Patent CA-2217071-A1 (CA)
Inventor: MARCO LESLIE S
IPC: B65D71/50
Filed: 1997-09-30
Abstract: A sheet that cooperates with a traditional ring carrier to create a package that covers openable ends of unitized substantially similar cans. The ring carrier unitizes an array of cans into longitudinal ranks and transverse rows. The sheet contains an array of longitudinal, substantially parallel pairs of slits corresponding with the arrayed cans. The corner slits are substantially curved and promote a positive corner wrap at the corner end of the slit. A slit transversely adjacent the corner slit is curved and a slit longitudinally adjacent to the corner slit is straight for most of its length. Two integral flaps extend transversely with respect to the sheet and are folded with respect to the remaining portion of the sheet through an angle greater than 90°. Clipping the sheet onto the array of cans unitized by the ring carrier creates an assembled package. Portions of the sheet adjacent each pair of slits engage a portion of the chime of each corresponding can. Because of the slit and pre-folded integral flap configurations according to this invention. the integral flaps remain in a substantially flat position with respect to the sidewalls of the outside rows of cans.

IPC: H01S3/00
Filed: 1997-10-06
Abstract: An improved four-port dichroic WDM, for use in a multiwavelength, bi-directional optical amplifier, having a dichroic filter for substantially reflecting a first wavelength band input to the WDM to an output of the WDM for the first wavelength band and for substantially transmitting a second wavelength band input to the WDM to an output of the WDM for the second wavelength band, in which some of a first 3dB wavelength in the first wavelength band is transmitted by the filter and some of a second 3 dB wavelength in the second wavelength band is reflected by the filter, includes another dichroic filter having a filter function different than the filter function of the WDM filter providing an insertion loss for the first or the second 3 dB wavelengths sufficient to reflect and transmit, respectively, substantially all of the first and second 3 dB wavelengths. Additional dichroic filter for suppressing 3 dB light are use to prevent Q-switching in a optical gain cavity in a multiwavelength, bi-directional optical amplifier formed by a reflection point in an optical path connected to the amplifier.

Title: Wine bottle and closure therefor
Inventor: REID GRAHAME W
IPC: B65D41/58
Filed: 1996-04-10
Abstract: A wine bottle closure (11) includes a gasket/stopper (25) which engages the neck of the bottle (10). Encasing the finish (17) and upper neck (19) of the bottle is a plastic outer closure cap (13), generally cylindrical, with a top center disc (15) which is adhered to the top of the stopper (25). A circle of frangible elements (61, 62) at the periphery of the disc provides for breakage of the disc away from the closure sleeve (16), causing it to remain with the stopper when the plastic cap is opened. Coarse, short-length threads (23) are formed on the outside of the container neck, spaced appreciably below the finish, to be engaged by internal thread lugs (43) of the plastic cap.  On initial unscrewing of the cap, the disc breaks away from the remainder of the cap. A small vertical clearance (66) is provided in the engagement between the internal cap structure and the gasket/stopper, so that the cap does not begin to lift the gasket/stopper until static friction against the elastomeric gasket/stopper has been overcome.

Title: Method of making herpes simplex type 1 mutants and mutants so produced
Inventor: SHAFER JULES A
IPC: C12N9/50
Filed: 1996-05-28
Abstract: A method for introducing a mutation into a desired site in Herpes Simplex Virus Type 1 uses a set of starting vectors, where each starting vector has a fragment of the substantially complete HSV-1 genome and also DNA which overlaps with a sequential genomic fragment contained in other starting vectors, so that upon co-transfection of a host cell, replication of viral DNA, and recombination, a mutated replicable virus is formed. The starting vector containing a gene which is to be mutated is replaced by replacement vectors. The replacement vectors contain a copy of the mutated gene and overlapping DNA, and genomic DNA which was present in the starting vector. A host cell is transformed with the replacement vectors and the remaining starting vectors under conditions allowing replication of viral DNA and recombination to form a replicating mutated virus. In preferred embodiments, the protease gene is mutated.

Title: A self-provisioning names database for caller identification services
Inventor: DEFAZIO PAMELA LILLY
IPC: H04Q3/00
Filed: 1998-03-17
Abstract: A self-provisioning names database adds new names to a database for associating names to calling address data in a caller identification with name delivery service. A new caller's name is added to the database each time the newcaller places a call to a service subscriber. The database reaches only a nominal size in accordance with Perado's rule that approximately 80% of incoming calls to a subscriber will be from the same small group of callers. Alternatively or in addition, a new party's name is added to the database each time a service subscriber places a call to a party whose name is not already in the names database. Caller names that have been stored in the database and not retrieved for a long period of time are discarded to store new names. Also, the database may periodically request updated data for a stored name, for example, to determine if a different telephone number or address has been assigned to the given name data.
