Title: Membrane-associated immunogens of mycobacteria
Inventor: KAPOOR ARCHANA
IPC: A61K39/00
Filed: 1993-06-28
Abstract: Nucleic acid encoding four novel immunodeterminant protein antigens of M. bovis BCG, which is a vaccine strain for tuberculosis, have been isolated. These genes were isolated as immunoreactive recombinant clones from a genomic library of M. bovis BCG  DNA, constructed in pBR322 vector, and screened with sera collected from tuberculosis patients. The BCG DNA insert of one of the recombinants, pMBB51A, which expressed an antigen of Mr 90 kD, was sequenced completely and an ORF encoding 761 amino acids encoding a protein of deduced molecular weight 79 kD, was identified.  This gene was identified to encode a membrane bound, ion-motive ATPase of M. bovis BCG. The approach described here can be used to identify immunogens of mycobacteria. In addition, the well-characterized M. bovis BCG antigens can be used in the prevention, diagnosis and treatment of tuberculosis. The 79 kD antigen is also useful in the design of recombinant vaccines against different pathogens. The sequence of the 79 kD membrane-associated polypeptides also are useful for the development of specific PCR  amplification based diagnostic procedures for the detection of mycobacteria. Also, the promoter of the 79 kD antigen is useful for expressing homologous and/or heterologous antigens in mycobacteria.

Title: Process for controlling the control unit of a system for protecting vehicle occupant
Inventor: LEIRICH OSKAR
IPC: B60R21/01
Filed: 1993-12-23
Abstract: A process for controlling the control unit of a system for protecting vehicle occupants with a view to triggering the protection system if the accident  is sufficiently serious. The control unit contains one or more sensors, which supply sensor signals during the accident, and a computing unit. During the accident, the latter establishes on the basis of the sensor signals one ACTUAL value or a plurality of different ACTUAL values characterizing  the  course  of  the  accident.  It  also automatically and continuously redefines in each case a time-variable triggering threshold value, which is namely dependent directly or indirectly on the changes in the sensor signals during the course of the accident. Said computing unit compares one or more ACTUAL values with the triggering threshold value respectively assigned to the  ACTUAL  value.  However,  on  the  basis  of  the progression of the ACTUAL value/ACTUAL values, it defines the triggering threshold value at any instant in such a way that it changes in a fluctuating manner at least during  an  accident  phase,  namely  without  delay  in dependence on the  instantaneous value of the ACTUAL value/ACTUAL values, even if during this accident phase there occur constantly major decelerations without the direction collision altering.
