Title: Switching power supply unit
Inventor: HOSOTANI TATSUYA
IPC: H02M3/338
Filed: 2002-09-10
Abstract: A switching power supply unit includes first and second switching elements Q1,Q2 which are alternately turned on/off so as to perform self-excited oscillation. An inductor L and a capacitor C resonate during an OFF-period of the first switching element. After the second switching element is turned on, a resonance current applied to a series circuit including the second switching element and the inductor is interrupted before energy is completely emitted from a secondary winding T2. Accordingly, a voltage is generated at the inductor and a voltage at a transformer is reversed. The switching power supply unit also includes an ON-time control circuit in which a time constant is set so as to turn off the second switching element accordingly.

Title: Arrays of protein variants
Inventor: BLACKBURN JONATHAN MICHAEL
IPC: C12Q1/68
Filed: 2002-12-05
Abstract: By highly homologous or related it is meant those DNA coding sequences which share a common sequence and which differ only by one or more naturally occurring mutations such as single nucleotide polymorphisms, deletions or insertions, or those sequences which are considered to be haplotypes (a haplotype being a combination of variations or mutations on a chromosome, usually within the context of a particular gene). Such highly homologous or related DNA coding sequences are generally naturally occurring variants of the same gene. Arrays according to the invention have multiple for example, two or more, individual proteins deposited in a spatially defined pattern on a surface in a form whereby the properties, for example the activity or function of the proteins can be investigated or assayed in parallel by interrogation of the array.

Title: Suspensions of water-swellable polymer particles which are substantially water-free or contain insufficient water to fully swell the particles
Inventor: RICHARDSON JONATHAN CRAIG
IPC: A61K31/734
Filed: 2003-02-20
Abstract: A liquid composition for adherence to a surface, notably to a bodily surface, especially a mucosal surface, comprises water-swellable polymer particles suspended in a liquid diluent, wherein the liquid diluent is substantially free of water or includes an amount of water insufficient to fully swell the polymer particles. On admixture with water the composition thickens and becomes more adherent to surfaces. Thus the composition may be easy to administer but may become thick and adherent at the treatment site. The polymer particles may not comprise a mixture of anionic and cationic polymers. Preferred polymer particles are alginate particles and preferred diluents are glycerol, propylene glycol and polyethylene glycol or mixtures thereof. The compositions may be used to treat or prevent damage to or inflammation of a bodily surface.

Title: Silicon-on-Insulator biosensor devices
Inventor: ABSTREITER GERHARD
IPC: G01N27/414
Filed: 2003-05-15
Abstract: A semiconductor device 1 for the detection of specific biomolecular interactions is based on Silicon-on-Insulator (SOI) technology. The device comprises a substrate 2 having an SOI structure and an in-plane-gate field-effect transistor (FET) 3. The substrate 2 has, from bottom to top, a bulk silicon layer 22, a buried oxide layer 24, a single-crystal silicon layer 26. A thin, natural oxide layer 28 is formed on the silicon layer 26. The device surface is made biofunctional by binding receptors such as antibodies 46 to it. When an analyte such as a protein 52 binds itself to such a receptor it changes the device's surface potential. Any change of surface potential changes the lateral conductivity of the SOI layer 26. Such a biosensor device can allow the identification of specific interactions between biomolecules in a highly parallel and highly sensitive way.

Title: Mediated RSA cryptographic method and system using blinding
Inventor: CHEN LIQUN
IPC: H04L29/06
Filed: 2004-06-09
Abstract: A mediated RSA cryptographic method and system is provided in which a sender (10) encrypts a message (m) using an encryption exponent <B>e</B> and a public modulus <B>n</B>, and a recipient (20) and a trusted authority (50) cooperate with each other to decrypt the encrypted message by using respective components <B>dU</B>, <B>dT</B> of a decryption exponent. In order to prevent the trusted authority (50) from reading the message in the event that it has access to the recipient decryption exponent components <B>dU</B>, the recipient (20) blinds the encrypted message before passing it to the trusted authority (50). This blinding is effected by a modulo-<B>n</B> blinding operation using a factor <B>r<e></B> where <B>r</B> is a secret random number. The trusted authority (50) then applies its decryption exponent component <B>dT</B> to the message and returns the result to the recipient (20) who cancels the blinding and applies its decryption exponent component <B>dU</B> to recover the message. In a preferred embodiment, the encryption exponent is based on a string (STR) comprising one or more conditions; this string is passed to the trusted authority (50) along with the blinded message and the trusted authority checks that the or each condition is satisfied before it determines and applies the appropriate decryption exponent component <B>dT</B>. In a further embodiment the encryption exponent is based on a string chosen by the sender such that identifier-based mediated RSA is performed.

Title: Eddy current analysis
Inventor: HOPKINS NOEL PAUL
IPC: G01N27/90
Filed: 2004-10-12
Abstract: Eddy current probes 2 have been utilised for analysing materials non destructively, but such analysis is degraded when used with materials which are temperature sensitive electrically such as abradable coatings. These coatings include a significant proportion of non metallic discontinuities and act like a semi-conductor rather than a conductive material. An arrangement 1 is provided in which heating is achieved through for example electrical coils 3 until the material to be analysed is elevated to an appropriate stable isothermal temperature whereupon the probe 2 is activated for analysis. Typically, a thermocouple 5 is provided to detect the stable elevated temperature for the material and eddy current probe analysis is performed within seconds of achievement of that stable temperature. A jacket 6 used to surround the probe 2 includes the heating means 3.
