Patent CA-2330710-A1 (CA)
Inventor: TORABI MOHAMMAD
IPC: H04L12/44
Filed: 2001-01-10
Abstract: Abstract The relay service control procedure enables network operators and/or service providers to provide home services to the visiting user, who is located in a visited serving network, when the visited serving network is not equipped to offer the home services. This is accomplished by enabling the visited serving network to expand their portfolio of available wireless services on an as needed basis. It obtains the needed Service Logic Program (SLP) from the Service Control Function of the user's home network or the Service Control Function of any other supporting network in the wireless communication system that supports the requested service. The visited serving network executes the relayed Service Logic Program in its Service Control Function and directly controls the provision of the requested service to the visiting user. The use of a supporting network for wireless telecommunication systems assists in the execution of the relay service control procedure to provide desired services to the mobile terminal users, directly through the inter-connection of the visited serving network with the supporting network. The network inter-connection is achieved by the use of a unique Network-to-Network Interface protocol that enables a supporting network operator to become a purveyor of third generation mobile telecommunications services to subscribers who are presently served by wireless communications networks that are incapable of providing these services.

Title: Anti-copying methods and devices for digital information signals
Inventor: WIJNEN ARIE MARINUS
IPC: G11B20/12
Filed: 1999-05-04
Abstract: In order to protect audio signals against copying, it is proposed to mix the  audio signal with at least one non-audible disturbance signal. A first disturbance signal may be a low-frequency signal which is added to the audio  signal, while a second disturbance signal may be a high-frequency disturbanc e signal which is multiplied with the audio signal. Additionally, the second disturbance signal may be modulated by a modulating signal comprising either  the original or inverted orginal signal, or spoken messages indicative of an  illegal copy. Additionally, or alternatively, digital information may be cop y protected by briefly interrupting the writing of the information to an information carrier. The latter measure is also effective for copy protectin g software.

Title: Protein and its encoding nucleotide sequences for diagnosis, prevention and treatment of lung injuries and disorders
Inventor: CLIPPE ANDRE
IPC: C12N15/11
Filed: 2001-02-07
Abstract: The present invention describes the identification of a novel protein P-SCGB  belonging to the family of uteroglobins/secretoglobins, and nucleic acid sequences encoding said protein. Said protein and nucleic add sequences are useful in the diagnosis and/or treatment of lung injuries and diseases, and of inflammation or immunomodulation-related disorders. More particularly said protein and nucleic add sequences are useful in the diagnosis and/or treatment of asthma. The new protein is specific for the lung and has a small size facilitating its transepithelial leakage from the lung into serum. It therefore has all the features to serve as a peripheral lung marker.  Furthermore, its homology with members of the uteroglobin/secretoglobin family make it a potentially important protein that may be used as a diagnostic or therapeutic tool for many other pathologies.

Abstract: A device for generating a spreading code in a CDMA communication system is disclosed. In the device, an ML (Maximal Length) sequence generator generates an ML sequence according to a generator polynomial of an ML sequence having a length 2S-1 and a given initial value, and reloads the initial value whenever an ML sequence having a length shorter than the length 2S-1 is generated, to repeatedly perform an operation of generating the ML sequence. A mask selector including first and second masks having a given offset, selects the first mask in an ML sequence period and selects the second mask in the other period. A  modulo-2 adder adds an output of the ML sequence generator and an output of the mask selector to generate the spreading code, and truncates the ML  sequence upon receipt of the second mask.

Inventor: JOHNSTON JEFFREY M
IPC: G03F7/40
Filed: 2000-05-30
Abstract: The combination or hybridization of chemical machining (especially photochemical machining, chemical resist machining or thermal resist machining) with electrical discharge machining provides an increased efficiency machining process with unique etch characteristics and improved economics. The ability of chemical machining to accurately and rapidly machine a substrate to significant depths is combined with the increased flatness of wall or slope facings of the slower, but more precise, electrical discharge machining to provide three-dimensional patterning of surfaces with facial characterictics that are unique, rapidly obtained, and of high quality. The process is performed by either (a) first chemical machining to obtain the fundamental pattern and approximate depth of texturing desired in the final product and refining the grooves, walls and troughs of the patterned surface by subsequent electrical discharge machining or (b) using electrical chemical machining to define a pattern of troughs, grooves and walls, and then extending the depth of those grooves with chemical machining (in combination with a resist over the surface of the plateaus of the initial pattern). The initial product from alternative (b) may be followed by a further electrical discharge machining to refine the groove characteristics.

Filed: 1999-11-19
Abstract: La présente invention concerne le transfert génique et la technologie de thérapie génique, notamment des compositions et des procédés d'apport ciblé de virus. Le procédé se fonde sur l'utilisation d'un procédé qui mélange des virus, qui peuvent comprendre un virus recombinant exprimant une protéine ou un acide nucléique d'intérêt, et un ligand tel que la transférine ciblant une cellule. On mélange le virus et le ligand sans utiliser d'agents de réticulation ou d'agents liant par liaison covalente le virus et le ligand. Ce mélange simple provoque une plus faible inactivation en comparaison à la liaison chimique du ligand au virus et permet de ce fait de créer une composition thérapeutique plus active que celles obtenues par des procédés recourant à des agents de réticulation.
