Patent CA-2205175-C (CA)
Inventor: LIU MARGARET A
IPC: A61K48/00
Filed: 1995-11-13
Granted: 2008-02-19
Abstract: Genes encoding Mycobacterium tuberculosis (M.tb, proteins were cloned into eukaryotic expression vectors to express the encoded proteins in mammalian muscle cells in vivo. Animals were immunized by injection of these DNA constructs, termed polynucleotide vaccines or PNV, into their muscles. Immune antisera was produced against M.tb antigens. Specific T-cell responses were detected in spleen cells of vaccinated mice and the profile of cytokine secretion in response to antigen (85) was indicative of a Th1 type of helper T-cell response (i.e., high IL-2 and IFN-.gamma.). Protective efficacy of an M.tb DNA vaccine was demonstrated in mice after challenge with M.bovis BCG, as measured by a reduction in mycobacterial multiplication in the spleens and lungs of M.tb DNA-vaccinated mice compared to control DNA-vaccinated mice or primary infection in naive mice.

Title: Unlocked w-band receiver with coherent features
Inventor: KRIKORIAN KAPRIEL V
IPC: G01S13/00
Filed: 1997-05-15
Granted: 2000-07-11
Abstract: A coherent radar receiver that has pulse-to-pulse coherence using an unlocked voltage controlled oscillator, such as a Gunn voltage controlled oscillator. The present invention is a W-band, for example, bistatic receiver that uses a scanning sum channel antenna to scan the target, a downconverter for downconverting received alternating sum and difference pulse echoes from the bistatic illuminator to provide video signals, and processing circuits for processing the downconverted the video signals to precisely locate the null position on the target. A Fourier transform circuit, magnitude detector and a peak detection and centroid circuit are used to generate a voltage frequency control output signal that is applied to the voltage controlled oscillator or local oscillator that controls its frequency. An angle estimation algorithm is used that processes the video signals to locate the null offset from the center of a scan pattern generated by the antenna. The present invention thus provides for an inexpensive weapon receiver at W-band, for example, using an inexpensive unlocked voltage controlled oscillator. The pulse-to-pulse coherence achieved by the receiver permits precise location of a target of interest from bistatic radar returns.
