Patent AU-2002216213-A1 (AU)
Title: Tissue growth method and apparatus
Inventor: BROWN ROBERT ALBERT
IPC: C12M3/00
Filed: 2001-12-19
Abstract: A method for growing tissue in vitro includes the steps of: (i) providing a deformable substrate which is seeded with tissue-forming cells and which defines at least one flow channel containing a fluid culture medium; (ii) applying, substantially parallel to the flow channel, a cyclically varying load to the substrate, which load deforms the substrate to provide mechanical cueing for the cells; and (iii) inhibiting the flow of culture medium in one direction of the flow channel so that the deformation of the substrate causes a net flow of the culture medium along the flow channel in the opposing direction, thereby refreshing the culture medium in the flow channel.

Patent AU-2002227095-A1 (AU)
Title: Apparatus and method for providing optimal adaptive forward error correction in data communications
Inventor: COOPER MICHAEL J
IPC: H03M13/35
Filed: 2001-11-30
Abstract: An adaptive and dynamic forward error correction scheme for a communication channel is disclosed. The method and apparatus calculates the actual bit error rate for comparison with a target bit error rate. When a channel is performing better than required by the performance specifications, the forward error correction power can be reduced to provide greater throughput. If the calculated actual bit error rate is greater than the target bit error rate, then the forward error correction power is increased in an attempt to lower the calculated bit error rate. A feedback loop is employed to continually calculate revised bit error rates as the forward error correction power is increased or decreased.

Title: Systems and methods for characterizing television preferences over a wireless network
Inventor: RISSANEN JUSSI
IPC: H04N7/173
Filed: 2001-06-11
Abstract: A system for interacting with viewers of television programming includes a television set and a network terminal for each such user. The terminals are connected by the network to an interactive server which maintains a first database of persistent information for each user and a second database of current preference information for each user. The current preference information includes registrations of users as viewing particular programs or as participating in certain activities chronicled in television programs, such as lotteries, polls, and product promotions. According to information in the first and second databases and according to current user requests, the interactive server forwards information to users' terminals, modifies content of all television programming, or modifies content of television programming targeted to certain users or groups of users for selection by those users' cable or satellite set-top boxes.

Title: Method for sealing a pouring opening of a container and container comprising a sealed pouring opening
Inventor: KLATTE BERND
IPC: B65D47/08
Filed: 2000-09-12
Abstract: The invention relates to a method for sealing a pouring opening of a container and a container with a corresponding structure.  A sealing element (18) which covers the opening, composed of a flat layered material, is connected to an edge area (17) of the container (1) all around the opening, preferably by welding.  The sealing element is further connected, or glued to the hinged lid (11) of a sealing cap (4) mounted onto the container, said hinged lid covering the pouring opening.  The adhesive strength of the connection between the sealing cap and the hinged lid is greater than that between the sealing element and the edge area of the container.  In order to separate the sealing element from the edge area of the container, the hinged lid must be pivoted away.  The arrangement of the container and sealing cap is particularly suitable for the conservation of chemical substances in powder form and can be used for example in photo developing machines.  The opening of the hinged lid can take place mechanically in order to allow access to the contents of the container.

Patent WO-02055837-A1 (WO)
Inventor: WALTER BRUNO
IPC: E21B21/10
Filed: 2002-01-09
Abstract: Des impulsions de pression de haute intensité se propagent vers le bas par un train de forage pour arriver dans un trépan. On peut générer ces impulsions en créant un coup de bélier dans la boue de forage coulante. On augmente l'intensité des impulsions acoustiques dans les buses du trépan. On peut utiliser ces impulsions pour commander le fonctionnement de divers outils de fond de puits. Un premier type d'outils comporte plusieurs pistons montés en série. Des impulsions de haute pression déplacent les pistons pour créer de fortes vibrations mécaniques dans le train de forage, réduisant ainsi les exigences de couple.

IPC: H01M50/583
Filed: 1989-11-02
Abstract: A cell bypass circuit is disclosed which includes a diode 32 connected electrically in parallel with a cell 20 of a battery 12.  A thermal switch 34 is mounted in thermal contact with the diode 32.  A relay 38 including a coil 36 and a contact 40 is provided.  The coil 36 is connected to the thermal switch 34 so as to be activated by the activation thereof.  The contact 40 of the relay 38 is connected in parallel with the cell 20 so that the activation of the diode 32 causes thermal energy to radiate therefrom activating the thermal switch 34.  The activation of the thermal switch 34 causes the activation of the relay 38 which in turn places an electrical short across the defective cell 20 via the contacts 40 thereof.

Title: Interference connection between a heating element and body of a glow plug
Inventor: SHAFER SCOTT F
IPC: F23Q7/00
Filed: 1990-06-29
Abstract: Abstract of the Disclosure Interference Connection Between A Heating Element And Body Of A Glow Plug An improved mechanical joint structure is provided and adapted for positively retaining a heating element within a bore of a body of a glow plug.  The glow plug includes a body, a heating element and a ferrule,  The ferrule is sealingly positioned radially between an internal surface of the body bore and a peripheral surface of the heating element.  The glow plug further includes a compressing structure for positively compressing an internal surface of the ferrule against the peripheral surface of the heating element in response to the heating element being forced into the body bore by, for example, the gas pressure developed in an operating engine combustion chamber.          Unlike conventional brazed or interference joints used in typical glow plugs, the present invention provides a normal force (Fn), for sealing the heating element, and an axially-directed frictional force (Ff), for retaining the heating element, which both increase as the heating element is forced deeper into the body bore.
