Title: Coherence multiplexed optical telephone network using optical power supply
Inventor: AL-CHALABI SALAH A
IPC: H04B10/80
Filed: 2001-06-15
Abstract: An optical telephone and communication system with interferometers at the transmitter and receiver using optical time-delay difference and differential frequency shift modulation and multiplexing techniques. The power to the system is provided from either a remote optical source through the optical network or a local optical source. The optical network provides one or two optical connections to the sets. Part of the optical signal from the network is converted to electrical energy stored in a rechargeable battery. The optical sources used must have a defined coherence function, wavelength and coherence length Lc. The transmitter converts the information to phase variation in one arm of the transmitter interferometer and the receiver recovers this signal by using a matched interferometer. The path imbalance between the two arms of either interferometer is greater than Lc. Each set is a assigned a particular time delay difference and or differential frequency shift for addressing.

Patent GB-2372326-A (GB)
Title: Oxygen sensor
Inventor: WILLIAMS EDWARD WATKIN
IPC: G01N33/00
Filed: 2001-09-11
Abstract: An oxygen sensor that can be regenerated for continued use comprises a layer of a composition comprising a semiconductor metallic oxide and a catalyst in which a surface of the layer has been treated to have oxygen depletion. The oxygen depletion is achieved by heating, however over a period of time the surface will regain its oxygen content and the depletion needs to be restored by further heating cycles prior to use of the sensor. The metallic oxide is typically stannic oxide or indium oxide, with the catalyst typically being platinum. The regenerated sensor is robust and has a longer lifetime than conventional sensors.

IPC: B41J2/175
Filed: 1999-05-18
Abstract: An ink cartridge 41 (Fig.6(a)) includes a semiconductor storage memory 61 (Fig.7(b)) mounted on a rear surface of a circuit board 31 wherein the memory is connected to external contacts (29,Fig.7(e)) via a series of contacts 60 (Fig.7(c)). The contacts are formed in an upper row and a lower row with the upper row comprising a middle contact 60-1 and a respective separate end contact 60-1,61-1 on both sides thereof and the lower row having a respective separate end contact 60-1 at each end of the lower row. The arrangement being such that electrical connections can be made with the end contacts of the upper row without those connections having first been made with the end contacts of the lower row when the cartridge is installed in a printer. As a result, the data in the semiconductor memory is securely prevented from being lost by the application of signals in an inappropriate order.

Title: Updating computer files on wireless data processing devices
Inventor: MUTTIK IGOR GARRIEVICH
IPC: H04M1/724
Filed: 2001-12-12
Abstract: A wireless data processing device 2 stores partially completed versions of a file needed to replace a current version of a file used by that device 2. When another device storing a more up-to-date version of the file than the current complete version stored by the device 2 moves into range, downloading of that new version either completely, or resuming from a previously reached point, is initiated. When the inrange device has more than one version of the file that could be downloaded, the version selected for initial download may be the one which will take least time to complete. When all parts of the new version have been downloaded the old version is replaced and out-dated parts are discarded.

Title: Transmission of encrypted and digitally signed files over the internet
Inventor: CHAN YUAN-CHAU
IPC: H04L29/06
Filed: 2002-04-26
Abstract: In a system 1 for network file transmission, files for transmission can be encoded and assigned with digital signatures, allowing users to authenticate the digital signatures, and to securely transmit and receive the encoded files through Internet, without connecting to a cyber telephonic network. A file is transmitted by encoding a file for transmission via a user at a sender terminal by using the file encoding/decoding module 3 and a public key of a receiver at a receiver terminal, so as to convert the file into an encoded file; transmitting the encoded file via the file processing module 4 through Internet to the receiver terminal; and decoding the encoded file via the receiver of the receiving system upon receiving the encoded file, by using a private key of the receiver and the file encoding/decoding module, so as to retrieve the file.
