Title: Method for measuring de novo t-cell production in humans
Inventor: KOMANDURI KRISHNA V
IPC: G01N33/50
Filed: 1999-06-30
Abstract: The present invention relates to a method for measuring de novo T-cell production in humans, and more particularly to the assessement recent thymic emigrant (RTE) diversity in a T-cell sub-population of a patient by the detection of T-cell receptor .beta. chain DNA deletion circles (TCR.beta.DC) generated during TCR gene rearrangement of thymocytes in the thymus. The method comprises isolating a T-cell sub-population from a patient, extracting genomic DNA from the T-cell sub-population, amplifying the genomic DNA with a primer specific for a T-cell receptor .beta. chain DNA rearrangement deletion circle (TCR.beta.DC) family and detecting the TCR.beta.DC, the TRC.beta.DC being indicative of the presence of a RTE. The method assesses the quantitative and qualitative (diversity) intrathymic T-cell production by quantitating the relative frequency and diversity of RTEs within various sub-populations of circulating human T-cells. Such a method may be useful to study the diversity of the human thymic function and to monitor immune reconstitution of HIV patients.

Title: Improved method and apparatus for protecting public key schemes from timing and fault attacks
Inventor: SHAMIR ADI
IPC: H04L9/30
Filed: 1998-05-12
Abstract: Improved methods and apparatus for protecting pub-lic key schemes based on modular exponentiation (including RSA and Diffie-Hellman) from indirect cryptanalytic tech-niques such as timing and fault attacks. Known methods for making the implementation of number-theoretic schemes resistant to such attacks typically double their running time, whereas the novel methods and apparatus described in this patent add only negligible overhead. This improvement is particularly significant in smart card and software-based implementations, in which the modular exponentiation operation is quite slow, and doubling its time may be an unacceptable solution.

Title: Re-encoding decoded signals
Inventor: FLETCHER JOHN ANDREW
IPC: H04N7/50
Filed: 1998-07-20
Abstract: If a signal is repeatedly encoded and decoded, coding noise generally accumulates as it passes through the various coding systems.  The present system provides means for preventing this, by providing means for identifying, at the second coding system, which coding system was previously used. The second coding can then use the same system as the previous coding. This use of matching coding systems results in very little extra coding noise being introduced by the second coding. The input signal is coded by two different encoders (11 and 12), their outputs are decoded and compared with the input signal at (20 and 21), the differences accumulated at (22 and 23). The smaller of the differences is used by selector (13) to select the encoder which matches the previous coding of the signal. The principles can be extended to MPEG Layer II Audio Coding and similar block coding systems.
