OSI Systems Receives Two Advanced Technology Contracts from the U.S. Domestic Nuclear Detection Office

  
    
  
  
    
      OSI Systems, Inc. (NASDAQ: OSIS), a vertically-integrated provider of 
      specialized electronic products for critical applications in the 
      Security and Healthcare industries, today announced that its Security 
      division, Rapiscan Systems, has been awarded two advanced technology 
      demonstrator (ATD) contracts for $1.6 million from the U.S. Domestic 
      Nuclear Detection Office (DNDO). The contracts are incrementally funded 
      and if all options are subsequently exercised, the total contract award 
      could total approximately $14 million.
    
    
      The first contract is for the development of a cargo inspection system 
      that is easily deployable and capable of automatically detecting fissile 
      special nuclear material (SNM) and differentiating it from 
      non-fissionable materials.
    
    
      The second contract is for the development of a hybrid cargo inspection 
      system that combines x-ray imaging and neutron detection to identify 
      nuclear fissionable material. This hybrid system will incorporate the 
      Company’s proprietary Auto-Z algorithm that provides automatic detection 
      of high-atomic-number materials typically associated with nuclear 
      weapons as well as shielding materials used to diminish the detection of 
      nuclear weapons.
    
    
      Ajay Mehra, President of Rapiscan Systems, stated, “These contracts 
      require the unique combination of the expertise of our staff in 
      high-energy x-ray imaging, neutronics as well as in mechanical, 
      electrical and software engineering. Once successfully completed, these 
      threat detection and verification technologies will provide an 
      additional inspection capability that can play an important role in 
      protecting our nation from weapons of mass destruction being smuggled 
      into the country.”
