Title: Method for routing telephone calls to subscribers of different service providers within a common numbering plan area
Inventor: SONNENBERG EDWARD
IPC: H04Q3/00
Filed: 1996-06-28
Abstract: A method for enabling a plurality of Local Service Providers within common Numbering Plan Area (NPA) to serve Subscribers of the plurality Local Service Providers.  The method includes the step of assigning to each Subscriber of a Local Service Provider within the common Numbering Plan Area (NPA) a unique three digit code, hereinafter referred to as a service provider area (SPA) code.  The service provider area (SPA) code is used by the telephone system in the same manner presently used for routing calls made when a calling Subscriber dials the Numbering Plan Area (NPA) code of the called party. Here, however, the service provider area (SPA) code is not dialed by the calling Subscriber.  The dialed directory number, NXX-XXXX, of a called Subscriber subscribed to a different local area provider, is sent to a database (DB).  The database (DB) maintains a record of the relationships between the directory numbers of Subscribers and the service provider area (SPA) codes of the Subscribers.  The database (DB) retrieves the service provider area (SPA) code associated with the dialed directory number presently serving the called Subscriber. The call is routed as SPA-NXX-XXXX.  Because the ten digit format, SPA-NXX-XXXX, is the same as the present NPA-NXX-XXXX, ten digit format, existing signaling and routing mechanisms may be used to route the call.  Thus, each one of the Subscribers of each one of the plurality of local area providers is assigned a common service provider area (SPA) code, each one of the Subscribers having a different service provider area (SPA) code.

Filed: 1995-05-04
Abstract: Laser semi-conducteur (10) utilisant plusieurs puits quantiques (20) à contrainte compensée pour augmenter le gain dans des dispositifs à grande longueur d'onde (1,3 et 1,5 microns). Les structures (18) de puits quantiques à contrainte compensée contiennent une pluralité de couches de puits contraintes (20) et de couches d'arrêt contraintes (22), ces dernières (22) étant soumises à une contrainte égale et opposée à celle des couches de puits (20). Ceci a pour effet de relever la restriction relative à l'épaisseur normale des couches contraintes. En outre, les couches de puits sont dopées avec un dopage p pour augmenter encore plus le gain optique. Dans une autre forme de réalisation, on intègre dans un laser (100 et 102) couplé à un réseau de diffraction une pluralité de puits quantiques à contrainte compensée. Grâce au gain accru de la structure de puits quantique à contrainte compensée, on peut réaliser le réseau de diffraction sur la surface du laser avec une caractéristique de fort couplage de la lumière, ce qui permet de simplifier la fabrication et de raccourcir la longueur du laser.

Filed: 1995-06-20
Abstract: The present invention is a torso protection system having braided tubes (131) that inflate upon side or oblique impact to protect the torso of a seated vehicle occupant. Prior to inflation, the braided tubes (131) are mounted in the undeployed state along both sides of the occupant's seat (136, 137). When an impact is detected, a gas generator (133) generates gas, inflating the braided tubes (131). As the braided tubes inflate, their diameters increase and their lengths decrease substantially.     The braided tubes (131) then pull out of their storage locations and from bolsters on either side of the seated occupant. The inflated tubes (131) prevent the torso of the occupant from directly colliding with interior side structures of the vehicle and restrict the lateral motion of the occupant.

Title: Laser treatment of telangiectasia
Inventor: DUDLEY DENIS K
IPC: A61B18/20
Filed: 1997-02-28
Abstract: The present invention is a method of using a laser to coagulate blood vessels and, in particular, using wavelengths between 580-1000 nm delivered in a multiple pulse technique. The fluence required for photocoagulation and irreversible vessel injury is delivered in a sequence of pulses which allows for cumulative heating of the irradiated vessel.  Each pulse  utilizes  a  subthreshold  fluence  delivered  at  a calculated repetition rate based on the thermal relaxation time of the targeted vessels to allow for efficient heating. Using several pulses at a lower fluence than would be required if the energy were delivered in one pulse avoids the thermal shock wave which results in vessel rupture and unwanted hyperpigmentation.  Lower fluences also reduce the risk of epidermal injury and unwanted scarring.   This method is particularly useful in the treatment of leg telangiectasia.
