Title: Automatic invocation of mobile ip registration in a wireless communication network
Inventor: LIOY MARCELLO
IPC: H04L29/06
Filed: 2000-01-20
Abstract: A system and method for invoking the performance of mobile node registration in a wireless communication network. The system comprises a terminal device for transmitting and receiving packetized data and a communication device coupled to the terminal device. The communication device monitors the packetized data for an Internet Protocol (IP) address contained in an IP  address request. If the IP address request is for a static IP address the communication device waits for network movement information. Based on the received network movement information, the communication device solicits network address information. Upon receipt of the network address information, the terminal device then initiates Mobile Node registration. As a result, the Mobile Node registration is automatically invoked whenever the terminal device changes its network point-of-attachment.

Abstract: The invention relates to a method and an arrangement of assigning an information-category and a priority of exposure for spots or blocks of information in a digital information system (10) comprising interfaces for data and telecommunication (26) for round-the-clock transmission of information at places accessible to and frequented by a general public including places where television sets are placed, wherein a control centre (12) has communication interfaces (14) for coordinating and controlling projectors (22), wherein the control centre (12) is able to create and update an exposure list in real time. In said exposure list, it being determined how many times an information is to be exposed during a specific time period.  Single spots or blocks of information are assigned a specific information-category and a priority for exposure, which priority is decremented a specific unit of priority for each exposure. The information is displayed according to assigned priority, thus exposure interruption due to visual inaccessibility for information viewers is evened out during said specific time period for single spot or block information.

Patent CA-2363932-A1 (CA)
Inventor: OZUM BAKI
IPC: B03B5/34
Filed: 2001-11-23
Abstract: The present invention claims that for the management of segregating industrial tailings, such as tailings produced by oil sands, mining and coal industry, the tailings is thickened by using a suitable thickener producing segregated thickened tailings as thickener underflow and release water as thickener overflow. The production of segregated thickened tailings in the thickener is the key factor for fast recovery of the released water from the tailings stream. Thickener overflow is the release water, which is preferably reconditioned and recycled. The thickener underflow is the segregated thickened tailings, which can be converted to engineered tailings product and discharged for land reclamation, further consolidation of which would produce more release water.  As an example, the thickener underflow (segregated thickened tailings) can be blended with the coarser and finer fractions of the main tailings stream, at certain proportions, preferably with the help of chemical additives, to produce blended composite tailings.  Blended composite tailings can be disposed for land reclamation, further consolidation of which would produce more release water.

IPC: F24F11/04
Filed: 2001-01-31
Abstract: The present invention is an economizer (50) that is capable of mixing outside air and inside air while incurring a significantly low pressure drop across the return air damper. In one embodiment, the economizer (50) comprises a mixing chamber (56), a return air vent (52), and an outside air vent (54). The economizer (50) further comprises a plurality of curved return air dampers (62) moveable from an open position to a closed position to control the flow of return air to the mixing chamber (56). The economizer (50) further comprises a plurality of straight dampers (66) moveable from an open position to a closed position to control the flow of outside air to the mixing chamber (56). During operation of the economizer (50), a significantly lower pressure drop exists across the curved return air dampers (62) than in conventional economizers thereby reducing the amount of energy needed to operate fans to maintain the desired air flow.

Title: Micro fourchette d'etalonnage a facteur q eleve formee par une fibre optique mince et destinee a un microscope nsom
Inventor: DAVYDOV DMITRI N
IPC: G01Q60/18
Filed: 2000-07-20
Abstract: On décrit un microscope à champ proche optique (MCPO) à mode perpendiculaire dans lequel l'élément de détection de la hauteur utilisé est une micro-fourchette d'étalonnage piézo-électrique. La présente invention concerne un procédé et un appareil qui permettent de modifier et d'attacher une fibre optique à la fourchette d'étalonnage pour permettre ainsi à l'ensemble de maintenir les facteurs Q jusqu'à 9000, ces facteurs étant sensiblement plus élevés que ceux décrits jusqu'à présent dans la littérature pour des instruments construits avec une fourchette d'étalonnage. Le procédé consiste à réduire le diamètre du revêtement de la fibre optique jusqu'à 17-25 µm au moyen de diverses étapes de gravure chimique avant de fixer la fibre à la fourchette d'étalonnage. On observe une brusque remontée du facteur Q lorsque le diamètre <i>d</i> de la fibre diminue en dessous de ~25 µm. Une analyse, qui montre que la constante de force d'étirement d'une fibre courbe est proportionnelle à <i>d</i>?4¿, est utilisée pour rendre compte de la forte sensibilité du facteur Q au diamètre de la fibre. Ces facteurs Q élevés ont produit une sensibilité améliorée à la force et nous ont permis de construire un instrument à mode perpendiculaire sans utiliser d'éléments piézo-électriques de juxtaposition supplémentaires. Un MCPO amélioré opérant en mode force de cisaillement est également produit, pour ce faire, on réduit sur sa longueur, la fibre optique courant sur la longueur d'une des dents à une épaisseur comprise entre environ 50 et 60 µm.

Abstract: A polymer blend is prepared by dissolving chitosan and a second polymer in an acidic aqueous solution to form an aqueous polymer blend, dehydrating said aqueous polymer blend, and recovering said polymer blend. The second polymer may be selected from the group consisting of polyether glycols including polyethylene glycols; cellulose esters including cellulose acetate; poloxamers; polysaccharides including dextran and guar; polyvinylpyrrolidones;  polyvinyl alcohols; and mixtures or copolymers thereof. These polymer blends swell in an acidic environment and deswell in a more neutral or basic environment. This technology is valuable for the dispensing of biologically active material or drugs into a surrounding environment, especially the environment as is found in the gastrointestinal tract. Since the various polymer blends of the present invention are not covalently or ionically crosslinked, but are physically combined, each polymer in the physical blend maintains its original chemical structure, and therefore, is safe for oral or other routes of administration.
