Granted: 2010-10-26
Abstract: Procédé permettant d'établir et de gérer des connexions protégées de données, audio ou vidéo assorties d'échanges de clés, d'authentifications et d'autorisations protégés. Selon un mode de réalisation de la présente invention, une connexion sure à privilèges limités peut être établie à l'aide de l'identificateur d'une machine fiable, ce qui est particulièrement utile si l'utilisateur de la machine ne possède pas d'informations d'identification d'utilisateur appropriées pour l'authentification. En outre, la présentation par un utilisateur d'informations par défaut identifiant l'utilisateur provoque avantageusement l'intervention d'un administrateur de système, au lieu d'un refus global. Cette procédure décentralisée permet à de nouveaux utilisateurs d'accéder au réseau sans avoir à se présenter physiquement à une installation centralisée pour présenter leurs justificatifs d'identité. Dans un autre mode de réalisation de la présente invention, un utilisateur situé à distance peut se connecter à un réseau protégé avec des privilèges limités.

Abstract: La présente invention concerne une nouvelle composition pharmaceutique permettant l'administration d'antagoniste de dopamine N-0923 sous forme de dépôts. Pour la première fois, une forme de N-0923 en dépôt a été mise à disposition et permet, après application au patient, d'obtenir un taux de plasma approprié d'un point de vue thérapeutique pendant au moins 24 heures. Jusqu'à présent, N-0923 devait, en raison de la mauvaise biodisponibilité orale et de la courte demi-vie du plasma, être administré soit par perfusion, soit par l'intermédiaire de systèmes transdermiques. Des modes de réalisation préférés correspondent à des suspensions huileuses dans lesquelles la substance active N-0923 est présente dans une phase solide, ainsi qu'à des préparations pharmaceutiques anhydres de N-0923.

Title: Multilayered fibrous product and a process for the production thereof
Inventor: SILENIUS PETRI
IPC: D21H17/69
Filed: 2002-04-24
Granted: 2012-12-18
Abstract: The multi-layer fibrous product and a process for producing it. According to the present invention the fibre product comprises at least two overlapping fibre layers, whereby the one that forms the top layer of the product contains filler and is lighter than the layer under it and is at least essentially opaque. According tothe present invention the filler of the top layer consists at least partially of cellulose or lignocellulose fibrils, on which light scattering material particles have been precipitated. The present invention can be used, for example, to produce white surface liner with a lighter top layer without impairment of the strengthof the surface. Thus, the grammage of the layer can be at least about 5% by weight less than a top layer, which has the corresponding opacity and formation, and which has been produced from the same fibre material and mineral pigments.

Abstract: A fishing bobber includes a strike-indicating signal producing transmitter, e.g. a radio transmitter, for transmitting a radio signal to the fisherman when there is a strike on the line. The bobber includes a bobber body adapted to float on a body of water. A fishing line is connected to it during use. The signal transmitter, which may be a lamp, an audible alarm or radio transmitter is supported by and preferably housed within the bobber. Operatively connected to the transmitter are a pair of probes or electrodes for actuating the transmitter. A sensing means is connected to the probes to detect a current passing between them in response to a fish exerting tension on the fishing line to thereby operate the signal transmitter so as to signal the fisherman, e.g. by broadcasting, a radio signal to alert the fisherman when a fish has struck the bait. One preferred form the bobber includes a pair of electrical probes, i.e. electrodes coupled through a sensing circuit for actuating the signal transmitter when submerged in water by a strike on the line so as to permit an electrical circuit to be completed between the probes.

Abstract: A thermally printable commercially functional cash register tape produced from a thin machine direction oriented, heat stabilized, multi-layer, coextruded thermoplastic film is described. This thermoplastic tape replaces the currently used paper cash register tape. It will accept printing, has sufficient machine direction stiffness and sufficiently reduced surface electrical charges to function in conventional commercial cash register printers. The thermoplastic tape is much thinner than the conventional paper tape so a roll of the plastic register tape contains about 4.7 times the paper length of a typical cash register roll.

Title: Method and apparatus for selecting an encoding rate in a variable rate vocoder
Inventor: DEJACO ANDREW P
IPC: G10L25/78
Filed: 1995-08-01
Granted: 2011-02-01
Abstract: The present invention provides a method by which to reduce the probability of coding low energy unvoiced speech as background noise. An encoding rate is determined by dividing the input signal into subbands using digital subband filters (4) and (6) and comparing the energy in those bands to a set of thresholds in subband rate decision elements (12) and (14) and then examining those comparisons in an encoding rate selector (16). By this method, unvoiced speech can be distinguished from background noise. The present invention, also, provides a means for setting the threshold levels using the signal to noise ratio of the input signal, and the present invention provides a method for coding music through a variable rate vocoder by examining the periodicity of the input signal to distinguish the music from background noise.
