Patent CA-2203784-A1 (CA)
Inventor: NGUYEN VIET ANH
IPC: H04Q7/38
Filed: 1995-10-16
Abstract: A manual home location register (M-HLR) (52) for use in a cellular telecommunication system provides manual visitors in a visited network (51) with the same registration capabilities as automatic visitors from networks that have automatic roaming agreements with the visited network. The M-HLR  maintains a database of manual visitor information separate from the network's database of home subscribers and automatic visitors. Initial registration in the visited network by a manual visitor is recorded in the M-HLR and enables the manual visitor to roam freely between multiple mobile switching centers (MSCs) in the visited network without having to re-register in each MSC.

Title: Method and apparatus for easing the strain on legs and knees while on the ski lift
Inventor: GRIFFIN KATHLEEN C
IPC: A41B13/00
Filed: 1995-11-13
Abstract: A method and apparatus for supporting the weight of legs, boots, and skis of a skier while riding do a ski lift chair which uses a support strap of elongated flexible material attached at one end to each boot in conjunction with a boot attachment strap. The other end of each support strap extends up the back of a skier's legs attaching to the skier's body above the thigh area. The support strap attaches to either a pull tab, a reel, an elastic strap or an elasticized cord which retracts and draws taut the support strap so as to slightly elevate the skier's legs, boots, and skis and support their weight. Either the weight on the thigh and buttock on the support strap, a gear lock on the reel, or a union between a hook tab which attaches to the support strap and a pile strip which attaches to the ski apparel holds the support strap taut and maintains the legs, boots, and skis of a skier in the elevated position. Thus, the apparatus supports the legs, boots, and skis of a skier while riding on a ski lift chair and eases the strain on the skier's knees and legs.

Title: Self-optimizing detergent controller
Inventor: BAILEY CLYDE A
IPC: D06F34/06
Filed: 1995-12-12
Abstract: An apparatus and method for programming a controller to vary the concentration set-point of an additive as a function of time. The present invention insures that the additive is injected to the machine at proper times to allow for optimum efficiency and lowest cost. To vary the set-point according to the input parameters, the invention combines the features of a data entry device, a microprocessor, a clock, a controller, and sensors into one unit. The user may enter a time setting and set-point into the controller, along with control parameters which allow the machine to control the additive injection based on different user-defined scenarios. The microprocessor then reads the settings and outputs an appropriate set-point value from the microprocessor to the controller. Thus, the user can manually or automatically change the response function if and when conditions change.

Title: Improved devices for removing fibrin sheaths from catheters
Inventor: SUHOCKI PAUL V
IPC: A61B17/22
Filed: 1996-04-05
Abstract: A medical device (10) adapted especially to remove biological material (e.g., fibrin sheath) from the distal end of a patient internal catheter that includes a tubular element (12), a central wire (14) positioned within the tubular element, a snare wire (16) attached at one end (16a) to the central wire so as to form an acute angle therewith, and at its other end (16b) to the tubular member. The snare wire includes a proximally extending segment which follows a course of about 360 degrees about the distal end (12a) of the tubular member, and thus may be positioned adjacent the catheter's distal end. By effecting relative rotation between the central wire and the tubular member (for example, by rotating the central wire about its longitudinal axis while maintaining the tubular member stationary) will cause the snare wire segment to wrap around the catheter's distal end. Thereafter, manipulation of the device so as to advance the wrapped snare wire segment in a distal direction will strip the biological material from the distal end of the catheter.

Patent CA-2220780-A1 (CA)

IPC: H04W36/08
Filed: 1997-11-12
Abstract: Utilisation de techniques d'apprentissage dynamiques par un contrôleur de système afin de déterminer un sous-ensemble d'emplacements de cellules voisines vers lesquelles un transfert d'activité devrait être tenté. Un transfert d'activité peut être un simple transfert ou un enregistrement. Les emplacements de cellules voisines à choisir pour un transfert d'activité sont déterminés pour chaque emplacement de cellule au moyen du processus d'apprentissage dynamique. Dans une première version, l'apprentissage dynamique se fait par accumulation de données statistiques qui définissent la durée moyenne d'un appel pour chacun des emplacements voisins choisis après un transfert d'activité à chacun d'eux. Cette durée moyenne a l'avantage de pouvoir comprendre la durée d'appel totale applicable à deux transferts d'activité subséquents. Dans une deuxième version, l'apprentissage dynamique se fait par accumulation de données statistiques qui définissent la puissance de transmission maximale à partir de la station de base à laquelle le combiné a été transféré. Dans une troisième version, le temps pendant lequel se maintient le niveau de transmission à faible puissance de la station de base de laquelle le combiné vient d'être transféré est mesurée. Si cette durée est inférieure à une valeur numérique prédéterminée, on assume qu'une annulation s'est produite, et ce fait est mémorisé pour la cellule en question. Cette information est utilisée pour détecter les évanouissements par trajets multiples et empêcher les transferts prématurés en cas d'évanouissement par trajets multiples. Par la suite, un transfert est différé pour une cellule ayant un grand nombre moyen d'annulations.

IPC: H04L12/54
Filed: 1996-07-05
Abstract: When data cells are transmitted from a station and the cells belong to different logical connections, derived from various logical or physical sources, each source and thus connection may require a particular transmission rate, which is not to be exceeded. Then for each one of a number of successive time slots a queue (223) is arranged, the first current queue being the one pointed to by a pointer (225). The time slot queues (223) comprise in a consecutive order, identifiers of those connections for which a data cell is to be transmitted. The first position in such a queue indicates the connections, for which a data cell is to be sent with the highest degree of priority. The following positions indicate connections which have lower degrees of priority in a decreasing order. The first data cell in the time slot queue (No. 1) (223) as pointed to by the pointer (225) is then transmitted from the station and a cell belonging to the same connection is added (arrow 431) to that other queue (No. n+1), which has an adapted distance from the considered queue in the sequential order of queues, where this distance is calculated from the transmission rate for the connection, to which the transmitted cell belongs. After that the remaining part of the first queue (No. 1) is transferred to the next queue (No. 2) and placed in front of all the items in this next queue (arrow 429). The first queue (No. 1) is thus empty and the pointer (225) is stepped to point to this next queue (No. 2).
