Title: Method and device for certification of a transaction
Inventor: WARY JEAN-PHILIPPE
IPC: G06F21/33
Filed: 2002-05-28
Granted: 2007-09-11
Abstract: The problem of real-time neutralising or revoking of a X509-type certificate, belatedly available in a public database (BD) is solved by directly neutralising (35) in a mobile telephone (1) a sub-programme (26) of signature and/or transmission of certificates concerning transactions to be validated. Thus by doing so neutralisation is achieved in the ten minutes following the signalling, or the neutralisation request, whereas it requires 24 to 48 hours in normal administrative circuits (AE, PB).

Abstract: A fraudulent intruder can eavesdrop on a call by removing information about an encryption algorithm when a multimode mobile station sends an unprotected initial signaling message containing this information over the radio interface to the mobile telecommunications system. The attempt can be prevented in a universal mobile telecommunications system (UMTS) comprising at least two radio access networks providing mobile stations with access to a multimode mobile station, and at least one core network. During connection setup with a first radio access network, the multimode mobile station sends an unprotected initial signaling message that includes information about those encryption algorithms that the multimode mobile station supports when it communicates in a second radio access network.  The first radio access network saves some or all the information of it. Then it composes and sends an integrity-protected message that includes information about the encryption algorithms supported by the multimode mobile station in the second radio access network.

Title: Cartridge and recording apparatus
Inventor: ASAUCHI NOBORU
IPC: B41J32/00
Filed: 2003-08-08
Granted: 2009-11-17
Abstract: An ink cartridge 10 has a memory controller 15 that controls a series of processing that involves rewriting data into a memory 14. The memory 14 stores information regarding the ink cartridge 10, for example, a residual quantity of ink in the ink cartridge 10. A control unit 22 of a printer 20 gives the ink cartridge 10 an instruction including a specified address to execute operation of rewriting the data in the memory 14 (either an operation of erasing the existing data from the memory 14 or an operation of writing data into the memory 14). In response to the given instruction, the memory controller 15 rewrites the data at the specified address in the memory 14 and sends back a response signal or an acknowledgement representing completion of the rewriting operation, together with address-related information corresponding to the specified address. The control unit 22 receives the address-related information and verifies whether data has been rewritten correctly at a right address. This arrangement ensures a sufficiently high reliability in the operation of rewriting data into the memory.

Title: Method of using matrix rank reduction to remove random noise from seismic data
Inventor: TRICKETT STEWART ROY
IPC: G01V1/36
Filed: 2003-09-12
Granted: 2007-06-05
Abstract: A frequency domain based method using matrix rank reduction for removing noise from seismic data sets is provided using a variety of 3D eigen filtering techniques. A rank reduced grid of traces or proxy cube that is representative of an original grid of Traces, but that has a better signal to noise ratio results since the surviving data elements represent the bulk of the composite signal related to genuine reflectors - whereas the trivial elements replace a large portion of the composite signal related to random noise. There is no compression of the elements of the representative matrices. The use of a series of proxy cubes in place of the co- ordinate pair related original CUBEs of seismic data results in several advantages including reduced processing time and better accuracy at the boundaries of the subject section.

Title: Radiation detector
Inventor: WATADANI KOJI
IPC: A61B6/00
Filed: 2004-09-21
Granted: 2014-03-18
Abstract: The radiation detector according to this invention has a common electrode for bias voltage application formed on a surface of an amorphous selenium semiconductor film (a-Se semiconductor film) sensitive to radiation. The common electrode is a gold thin film having a thickness in a range of 100 to 1,000.ANG.. The gold thin film acting as the common electrode may be formed on the surface of the a-Se semiconductor film at a relatively low vapor deposition temperature and in a reduced vapor deposition time. This feature suppresses a generation of defects in the a-Se semiconductor film due to formation of the common electrode. The gold thin film for the common electrode is not so thick as in the prior art, but is 1,000.ANG. or less. With the reduced thickness, the common electrode has improved boding property with respect to the a-Se semiconductor film.

Abstract: The preferred embodiment includes methods and apparatus for locating a member within an aperture. One preferred apparatus generally includes a housing containing at least one rotatably connected ring, and a plurality of tie members spaced evenly about the ring's perimeter. The tie members are connected to the rotating ring and the housing such that rotation of the ring pulls the tie members taut across the inside of the ring. Rotating the ring in the opposite direction returns the tie members to their initial orientation. When the tie members are taut they urge elements passing through an opening towards the center. When the apparatus is installed in a drilling rig floor, it results in a simpler and more effective pipe centering technology than currently exists allowing pipe strings to be centered in the slip bowl or power slips so that the slips are easily and securely installed about the pipe string.
