Title: Method and apparatus for encryption/decryption of digital multisound in television
Inventor: ROTH GORAN
IPC: H04N7/167
Filed: 1991-03-22
Abstract: ABSTRACT   The present invention relates to methods and apparatus for encryption and decryption, respectively, of digital sound in television. The decryption takes place in two steps. The first step, encryption with running key, is achieved by adding modulo 2 a pseudo random sequence to the digital signal containing a sound information. The pseudo random sequence is preferably generated by a non-linear feedback register initialized by the control word. The second step involves encryption of the control word, thereby being transmitted to the receiver in ciphered form. The encryption is preferably achieved by a microprocessor also performing coding of the control word for forward error correction. The control word in turn is generated by a true random sequence generator. The invention enables an encryption that is secure against breaking without deteriorating the sound quality and also enables efficient handling of the key of the encryption.

Filed: 1991-06-21
Abstract: A biologically active composition made up of core particles having diameters  of less  than about  1000 nanometers  which are coated with  a  layer which  is designed to allow attachment of biologically active proteins,  peptides or pharmacological  agents to the microparticles.  When viral protein is attached to the core  particles,  the  result  is  a  viral  decoy which accurately mimics the native virus in both size and structure  while  being  entirely  devoid  of  virulent activity due to the microparticle core.  Other antigenic proteins or peptides are attached to provide molecules which  are  useful  in  raising  antibodies  or  as  a diagnostic tool.   Further, pharmacological agents are attached to the microparticles to provide pharmaceutical compositions.  The viral decoys are useful as vaccines for treating animals to elicit an immune response.

Title: Specific microbial strain detection method
Inventor: WHEATCROFT ROGER G L
IPC: C07H21/04
Filed: 1991-11-12
Abstract: ABSTRACT          A method of detecting a particular microbial strain amongst closely related microbial strains and other strains present in vast numbers is described.  Following transposition a unique DNA sequence comprising an endogenous transposable element and its flanking DNA sequence is generated.  This new sequence is an acquired characteristic, diagnostic for that strain and its progeny alone.  In one example of this method, DNA primers are chosen from a region which includes the uniquely located transposable element.  These primers are used to amplify the DNA for its subsequent detection, and hence the detection of the particular microbial strain.
