  • Patent number: 12254765
    Abstract: A method and system are disclosed for collecting and maintaining road event information, where point-based road event location data from transportation authorities, construction companies, vehicle sensors, or combinations thereof, is susceptible to location sensor errors, digital map errors, and/or map mismatching errors. Errors less than a selected threshold are filtered by categorizing or grouping reports of point-based locations into segments along links in a representation of a road, providing improved accuracy of reporting of road events.

  • Patent number: 7888490
    Abstract: Anthrax toxin, comprising of protective antigen (PA), lethal factor (LF) and edema factor (EF) is a major virulent factor of B. anthracis. Protective antigen, PA is the main component of all the vaccines against anthrax. The protective efficacy of PA is greatly increased if small quantities of LF of EF are incorporated into the vaccines. An ideal vaccine against anthrax should contain PA, LF and EF together, but this combination would be toxic. Therefore, the biologically inactive mutant preparations of PA, LF and EF may be used together for better immunoprotection. The present invention describes the method for generation of recombinant vaccine against anthrax, comprising of non-toxic, mutant anthrax toxin proteins. The procedure involves site-directed mutagenesis of the native genes of the toxin proteins, the expression and purification of the mutant proteins and finally characterization of these proteins.
