Title: Paging a mobile station within a public land mobile network (plmn)
Inventor: MAUPIN ALAIN
IPC: H04W68/00
Filed: 1997-12-03
Abstract: A first location update is performed whenever a mobile station enter a particular location area. Thereafter, in the event that the mobile station enters a designated home zone within the location area, a second location update is again performed to inform the serving mobile switching center (MSC) that the mobile station is currently located within the designated home zone. All paging messages for subsequent incoming calls are then broadcasted only within the cell areas associated with the designated home zone.

Patent CA-2278561-A1 (CA)
Inventor: SIMAN JAIME
IPC: A61M25/14
Filed: 1998-01-29
Abstract: A double lumen tubing which is adapted for use as a catheter. The tubing accommodate multiple sized guidewires and has increased resistance to kinking.  A lumen wall divides the outer tubular wall into the two lumens and has a central arcuate portion shaped to allow insertion of relatively large guidewires through one of the lumens, while still leaving space for smaller guidewires through the other lumen. Resistance to kinking is increased by varying internal diameters or axes of the interior lumen walls to increase the wall thickness of the tubing in selected areas, and by varying the thickness of the wall that divides both lumens in the middle or where the dividing wall meets the outer tubular wall.

Title: Reduced resistance device for producing ignition sparks
Inventor: MCDONOUGH JAMES M
IPC: F23Q2/46
Filed: 1998-02-05
Abstract: An apparatus is disclosed for providing more uniform lighter spark wheel actuation. Uniform actuation is facilitated in the apparatus according to the invention by reducing the formation of deep grooves and high ridges in the flint. In one embodiment of the invention, a spark wheel coil (10) formed from wire having at least one substantially flat side is utilized to reduce ridge formation. The spark wheel coil (10) includes pitting in a transversal direction made on the outer surface of the coil (10).   The pitting forms projections (12) which protrude from the core of the coil (10) and which, when contacting a pyrophoric flint (40) while the coil spring is rotated about its axis, produce a tangential cutting across the pyrophoric flint (40) to emit an ignition spark.

Patent CA-2291861-A1 (CA)
Title: Zinc finger protein derivatives and methods therefor
Inventor: GOTTESFELD JOEL M
IPC: C12Q1/68
Filed: 1998-05-27
Abstract: Zinc finger proteins of the Cys2His2 type represent a class of malleable DNA binding proteins which may be selected to bind diverse sequences. Typically, zinc finger proteins containing three zinc finger domains, like the murine transcription factor Zif268 and the human transcription factort Sp1, bind nine contiguous base pairs (bp). To create a class of proteins which would be generally applicable to target unique sites within complex genomes, the present invention provides a polypeptide linker that fuses two three-finger proteins. Two six-fingered proteins were created and demonstrated to bind 18 contiguous bp of DNA in a sequence specific fashion. Expression of these proteins as fusions to activation or repression domains allows transcription to be specifically up or down modulated within cells. Polydactyl zinc finger proteins are broadly applicable as genome-specific transcriptional switchhes in gene therapy strategies and the development of novel transgenic plants and animals. Such proteins are useful for inhibiting, activating or enhancing gene expression from a zinc finger-nucleotide binding motif containing promoter or other transcriptional control element, as well as a structural gene or RNA sequence.

Title: Cup lid having improved drink-through opening
Inventor: VAN MELLE HUGH
IPC: B65D43/02
Filed: 2000-02-21
Abstract: A disposable cup lid is provided for placement onto a drinking cup having a substantially circular cup rim which lies substantially in a single plane. The cup lid comprises a substantially circular and substantially planar top surface, and a downwardly facing cup rim engaging recess formed near the outer periphery thereof. The cup rim engaging recess extends from 300° to 360° around the periphery, and is defined at its outer side by a substantially circular, downwardly depending apron, at its inner side by a first downwardly directed recess sidewall, and at its top by a top wall between the downwardly depending apron and the downwardly directed recess sidewall.  The downwardly depending apron extends 360° around the periphery.  There is an arcuate portion of the top surface which extends radially outwardly to the downwardly depending apron, and which has a radially directed axis of symmetry. A  depressed "U"-shaped hinge is formed in the top surface in the region thereof occupied by the arcuate portion, and the "U"-shaped hinge is oriented so as to be perpendicular to the axis of symmetry. A fault line is stamped into the top surface in the arcuate portion, in a location opposed to the "U"-shaped hinge. The fault line is spaced radially inwardly from the downwardly directed apron by a distance which is at least equal to the width of the top wall of the cup rim engaging recess; and the fault line defines an outer extremity of a tear-back flap which, when torn back, will fold backwardly at the "U"-shaped hinge and will thereby define a drink-through opening in the top surface. Also, an upwardly extending lifting stub is formed in the arcuate portion of the top surface in a location thereof between the first fault line and the "U"-shaped hinge. The dimensions of the lifting stub are such that it may be easily grasped between the thumb and a forger of an adult hand, so that the tear-back flap may be torn back by a grasping and lifting action of the lifting stub, and so as to provide access to the drink-through opening.

Title: Method for subscribing telecommunication devices at cooperating stations connectable to the telecommunication devices by wireless telecommunication in wireless telecommunication systems, particularly dect mobile parts at dect base stations in dect systems
Inventor: KAMPERSCHROER ERICH
IPC: H04W12/06
Filed: 1998-08-27
Abstract: Disclosed are a method and a circuit configuration designed to compensate variations resulting from temperature, voltage and production by means of CMOS  image sensors which are exposed to radiation and generate, depending on the radiation intensity, electrical output signals below a logarithmic curve. The inventive method comprises the following steps: at least two reference CMOS  sensors, which are maintained at the same temperature as the CMOS image sensors to be compensated but are not irradiated, are used to generate two reference signals, one of which corresponds to a reference dark value and the other, as a result of electric power application thereupon, to a reference light value. The reference signals are amplified separately from each other in such a way that the amplification conditions are identical to those needed for amplifying the output signals to be compensated. Said reference signals are sent to an A/D converter with a thermal regime identical to that of the electrical output signals from the CMOS image sensors to be compensated. For each CMOS image sensor point at least one correction value is stored in a memory unit. The correction value, which enables variations resulting from temperature, voltage and production to be compensated, is fed into the system to correct the output signal to be compensated and obtain FPN=(fixed-pattern-noise)-corrected output signals. The FPN-corrected output signals and the reference signals received ared fed to the A/D converter, where the output signals from the CMOS image sensors are compensated and converted into digital signals. The circuit configuration according to the invention is so designed as to allow implementation of the method described.
