Title: Water treatment process
Inventor: DELIGHIANNIS ANDREAS TH
IPC: C02F1/70
Filed: 1997-11-07
Abstract: A process for the treatment of waste waters containing chemically reducible dissolved organic and inorganic pollutants and suspended matter in particulate or colloidal form. The process comprises contacting the water with metallic iron or ferrous ions (Fe2+), or mixtures thereof, in the presence of promoter metals, such as Cu, Pd, Pt, Au, Ag, and Ni, or oxides, sulfides and other insoluble compounds of these metals, which catalyze the redox reductions carried out by the iron or ferrous reagents. The production of ferric ions (Fe3+) as a final iron oxidation product allows for the simultaneous coagulation and precipitation of suspended colloidal and particulate solids out of the aqueous phase. In addition to the main reductive reaction scheme, the system performs a multitude of secondary reactions involving the ferrous and ferric ions produced in-situ which allows for the simultaneous removal of specific target polluants, such as phosphate and hydrogen sulfide. The net effect of a treatment in accordance to this invention is the decrease in a wide range of carbonaceous, nitrogenous and other targeted pollutants present in a waste water stream in a dissolved, colloidal or particulate form and the chemical conversion, commonly referred to as "softening", of non-readily biodegradable pollutants through a generally complex set of reactions and physical processes. As a result, the implementation of the process prior to or in parallel to conventional biological treatment makes the latter more feasible, more efficient, more economical in terms of both capital investment and operating cost and, also, the finally discharged water more compatible with environmental demands.

Title: Apparatus for improving vision and resolution of retinal images
Inventor: WILLIAMS DAVID R
IPC: A61B3/15
Filed: 1997-12-23
Abstract: An apparatus for improving vision and resolution of retinal images comprises a point source produced on the retina (101) of a living eye (100) by a laser beam (102). The laser beam reflected from the retina is received at a lenslet array of a Hartmann-Shack wavefront sensor (148) such that each of the lenslets forms an aerial image of the retinal point source on a CCD camera (146) located adjacent to the lenslet array. The output signal from the CCD camera is acquired by a computer (150) which processes the signal and produces a correction signal which may be used to control a compensating optical or wavefront compensation device such as a deformable mirror (118). It may also be used to fabricate a contact lens or intraocular lens, or to guide a surgical procedure to correct the aberrations of the eye. Any of these methods could correct aberrations beyond defocus and astigmatism, allowing improved vision and improved imaging of the inside of the eye.

Title: Automated emergency notification system
Inventor: SALIMANDO STEVEN CHARLES
IPC: H04M3/533
Filed: 1999-06-15
Abstract: An automated emergency notification system is disclosed. When practicing one embodiment of the present invention, a calling party places a phone call to an emergency service provider by dialing into a service provider network. The service provider network determines the identity of the calling party by accessing a subscriber database. The network determines a set of parties to be called by utilizing the identity of the calling party to access the set of parties to be called from an outcall database. The calling party pre-defines the set of parties to be called (i.e., before an emergency occurs) in the event of an emergency and stores this information in the outcall database. The service provider network then establishes the phone call between the calling party and the emergency service provider and also automatically places phone calls to each individual included in the set of parties to be called that was defined by the calling party. The service provider network will provide a pre-defined message to each individual called.
Patent CA-2277609-A1 (CA)
Inventor: VUKELICH ROBERT
IPC: B63B43/00
Filed: 1999-07-16
Abstract: The invention controls vehicle lift by automatically applying a downward force to the front of a vehicle whenever the front of the vehicle is a predetermined distance off the ground or water. The height of the front of the vehicle or the angle of the vehicle is monitored. This can be accomplished by mounting a distance or tilt measuring device, such as a gyroscopic device, an infrared transceiver, or any other suitable device known in the art, to the vehicle. When the height of the front of the vehicle from the ground or water, or the tilt angle of the vehicle, approaches an undesired level, the sensor device triggers a device that applies a downward force to the front of the vehicle. By automatically forcing the vehicle's front end in a downwardly direction whenever unwanted lift is imminent, the present invention eliminates the need to manually control lift, thereby allowing inexperienced drivers to operate the vehicle more easily and safely, and experienced drivers to operate it more efficiently.

Title: Procede et trousse de quantification et de sequencage d'acide nucleique d'analytes d'acide nucleique dans un echantillon
Inventor: LACROIX JEAN-MICHEL
IPC: C12Q1/68
Filed: 1998-03-18
Abstract: L'invention concerne un procédé d'analyse quantitative et qualitative d'une analyte d'acide nucléique dans un échantillon susceptible de contenir de l'acide nucléique. Ledit procédé suppose tout d'abord de mêler à l'échantillon un acide nucléique de contrôle et deux paires d'amorces. La première paire d'amorces sert d'une part à amplifier une région conservée de l'analyte d'acide nucléique, si ce dernier est bien présent dans l'échantillon, afin de produire un fragment conservé ayant une première longueur et, d'autre part, à amplifier l'acide nucléique de contrôle afin de produire un fragment de contrôle ayant une seconde longueur, différente de la première. Une seconde paire d'amorces sert à amplifier une seconde région de l'analyte d'acide nucléique afin de produire un fragment de séquençage. Un membre de la première paire d'amorces est marqué par un marqueur détectable et un membre de la seconde paire peut être marqué par un marqueur tel que la biotine, apte à capturer l'amorce. Le mélange est alors traité de façon à amplifier l'échantillon et l'acide nucléique de contrôle au moyen des deux paires d'amorces afin de produire un mélange d'amplification contenant des fragments conservés, des fragments de séquençage et des fragments de contrôle lorsque l'analyte d'acide nucléique est présente dans l'échantillon, et uniquement un fragment de contrôle lorsqu'il n'y a pas d'analyte d'acide nucléique dans l'échantillon. Ce mélange est analysé afin de déterminer les quantités relatives de fragments conservés et de fragments de contrôle dans le mélange d'amplification en vue de quantifier la quantité d'analyte d'acide nucléique présente dans l'échantillon, ce qui constitue le point de départ d'une réaction servant à déterminer la séquence du fragment de séquençage.

Abstract: La présente invention concerne un procédé et un dispositif permettant de corriger automatiquement les montants facturés à une organisation par un fournisseur de service, de façon à créer une facture ventilée entre entités d'une organisation. En l'occurrence, un écran affiche un organigramme d'entreprise donnant la liste de toutes les entités. On associe à l'entité désignée les services qui ont été assurés au profit d'une entité désignée par un ou plusieurs fournisseurs de services. Le procédé consiste alors à rectifier les montants facturés des services pour calculer les montants à refacturer. La rectification des montants facturés se fait en appliquant des paramètres de modification de taux et des montants divers. Les paramètres de modification de taux servent à rectifier le montant facturé, soit d'un pourcentage désiré, soit d'un taux fixe à chaque fois, soit encore d'un montant forfaitaire par service. Les montants divers viennent en sus des montants facturés. Après rectification des montants facturés, le procédé consiste à utiliser le montant de refacturation pour générer la facture.

Abstract: L'invention concerne une suture radioactive inhibant les réponses hyperplastiques intimes, avec aiguille et matériau pour suture à élément émetteur bêta radioactif. Cet élément est de préférence lié chimiquement à un substrat organique du matériau de suture. De préférence, ce matériau pour suture radioactive fournit un rayonnement bêta supérieur à 0,0002 uCi/cm. Un premier mode de réalisation préféré comprend les étapes suivantes: dépôt de l'aiguille et du matériau dans une enceinte de réaction close; une fois la suture dans cette chambre, introduction dans la chambre d'un élément à rayonnement bêta ionisé, de préférence du tritium ionisé; début d'un processus d'échange entropique où l'élément susmentionné est échangé contre des molécules d'hydrogène dans le matériau pour suture organique; une fois que le niveau recherché de tritium ou autre élément à rayonnement bêta est incorporé dans le matériau, rinçage de la chambre; rinçage de la suture, puis séchage, extraction hors de la chambre et emballage. Selon une autre variante, on fabrique la suture à partir d'un matériau en polypropylène organique. Un élément à rayonnement bêta, de préférence du tritium, est incorporé directement dans un squelette du matériau polypropylène organique. Ledit matériau qui est alors radioactif est extrudé pour former un fil à suture, qui est fixé à une aiguille à suture et emballé pour expédition et utilisation ultérieures. Même si la présente invention n'en fait pas une condition, le second mode de réalisation décrit fait intervenir du carbone 12 dans le matériau en polypropylène organique.

Title: Management of wireless control channel
Inventor: STRICKLAND STEPHEN GREGORY
IPC: H04J3/16
Filed: 1999-11-09
Abstract: A method that selects one of a plurality of priority schemes for scheduling messages for one of cyclically repeating sets of time slots of a control channel based on at least one of a plurality of characteristics of the state of the control channel. The state of the control channel is all information regarding what has arrived, what is queued, and what has been transmitted.  This includes the status of the queues, the messages awaiting transmission, along with their type and the time they have been waiting, the sequence of past transmissions, as well as other information. In one embodiment, in a control channel of a TDMA system where the hyperframe number is the characteristic used to select the priority scheme, a priority scheme is selected that assigns a voice page highest priority when the hyperframe number is an even number, and that assigns an R-DATA SPACH  notification highest priority when the hyperframe number is an odd number. In another embodiment of the invention, if there is a packed airlink message, the packed airlink message is scheduled in the time slot. If there are no packed airlink messages, then the method dynamically alters the priority of messages based on whether there is a voice page or an R-DATA SPACH notification in the message queues since at least the end of the time slot construction period of a corresponding time slot of a previous hyperframe. If there are no such messages and there is a non-packable message, the non-packable message is scheduled in the time slot, although if there are no non-packable messages and there is a voice page or R-DATA SPACH notification, it is packaged in an unpacked airlink message that is scheduled in the time slot. However, if there is a voice page or an R-DATA SPACH notification in any of the message queues since at least the end of the time slot construction period of the corresponding time slot of the previous hyperframe, the voice page or R-DATA SPACH is packaged in an unpacked airlink message that is scheduled in the time slot. This significantly reduces both the number of messages that are blocked and the number of messages timed out.
