Title: Method and apparatus for handoff within a communication system
Inventor: KOTZIN MICHAEL D
IPC: H04W36/08
Filed: 1998-10-27
Granted: 2004-08-03
Abstract: In a communication system (100) where a remote unit is given a time offset for a base station (102) and hands off to the base station (102) if the remote unit (113) can acquire the base station within a time window surrounding the time offset, a remote unit {113) utilizes the time offset of each base station (supplied by a serving base station (101) via downlink communication signal (116}) and searches for neighboring base stations within the time window surrounding its PN offset.  The time window surrounding an individual base station's PN offset is allowed to vary depending upon whether the communication system (100) is time synchronized. In particular, a base station (101) supplies the remote unit {113) with an indication that the communication system (100) is operating in a synchronized or an unsynchronized mode, and the remote unit (i 13) varies the time window (search window) accordingly.

Title: Hierarchical data network address resolution
Inventor: JAI BEN
IPC: H04L12/24
Filed: 2000-12-12
Granted: 2007-05-15
Abstract: A network server stores database tables for use in resolving labels into network addresses as requested by a remote browser client. Each user has an associated address-table which stores user defined labels associated with network addresses. Users may access other user's address-tables if such other users grant authority to do so. Each user defines the address-tables to be searched, along with a search order, to be used when the user requests that a label be resolved into a network address. During address resolution, the server will resolve a received label into the network address associated with the label as defined by the first accessed address-table which contains the label. The search order as defined by the user may be overridden for a particular address resolution request by an appropriate user command. In various embodiment, the network addresses may be WWW addresses and electronic mail addresses.

Abstract: La présente invention permet de prévoir l'aptitude d'un composé d'intérêt à moduler l'activité biologique d'un récepteur dans un organisme multicellulaire à partir de son interaction avec ledit récepteur en présence de divers membres d'un groupe de bio-clés. Les bio-clés sont des ligands, en particulier des peptides ou des acides nucléiques, connus pour modifier la conformation du récepteur. Ces données d'interaction constituent ce que l'on appelle une "empreinte digitale", qui est comparée aux empreintes de composés de référence aux activités biologiques connues et dont le récepteur assure la médiation. Dans la réalisation dite "en braille moléculaire" de la présente invention, les empreintes digitales de référence et de test sont basées sur des essais in vitro (acellulaires). Dans la réalisation dite "en braille cellulaire" de la présente invention, les empreintes digitales de référence et de test sont basées sur des essais cellulaires (mais non pas sur des essais d'organismes multicellulaires complets, ou de leurs organes ou tissus).

Title: Method for producing a specific antiserum against the universal tumorous antigen and method for diagnosing malignant tumours using said antiserum
Inventor: ERKHOV VALENTIN SERGEEVICH
IPC: C07K16/30
Filed: 1998-05-18
Granted: 2010-10-26
Abstract: The present invention pertains to the field of medicine and may be used for producing a specific antiserum as well as for carrying out immunological diagnoses of malignant tumours. This method for producing an antiserum involves sampling an embryo at the foetal stage from animals of a same genetic type so as to obtain a cell suspension.  After immunisation, this method involves sampling spleen cells from the animal, separating lymphocytes and immunising the animal of the same genetic line using the lymphocyte suspension. An antiserum is then obtained and cells originating from healthy organs of the same animals are added to said antiserum. The mixture is finally decanted and the liquid located above the sediments is filtered. In order to carry out a diagnosis, the filtrate is added to the subject's blood and the results are obtained by immuno-fluorescence, by blood tests or using other methods of immunological diagnosis. It is thus possible to diagnose a tumour when the reliable values obtained differ from reference values.

Title: A method relating to the handling of transactions in databases
Inventor: RONSTROM MIKAEL
IPC: G06F9/46
Filed: 1999-07-22
Granted: 2008-09-30
Abstract: The present invention relates to a method of handling the risk of a deadlock between simultaneous transactions (T1, T2) in a database (1). The method is based on allocating to respective objects (01, 02) in the database (1) a lockout queue (L1, L2) in which transactions (T1, T2, T3, ..., T8) that request access to an object (01, 02) are placed t o await the access to said object of a preceding transaction. The handling procedure comprises going through, or perusing, the lockout queues (L1) belonging to different objects (01) to detect so-called locking transactions (T1) that can cause a deadlock and, subsequent to detection, comparing said locking transaction with other transactions (T2, T6, T1, T7, T8) in other lockout queues (L2) therewith enabling the ris k of deadlock between a first and a second transaction (T1, T2) that have both requested access to the same first and second object (01, 02) to be detected. Combinations of transactions that are ongoing or active in the database and that, according to said comparison, can cause a deadlock are divided into locking and non-locking combinations respectively. Solely the detection of a locking combination will cause furth er action to be taken.
