Patents by Inventor Bruce Sangster

Bruce Sangster has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6550248
    Abstract: A method for generation of electricity is disclosed in which solar heat energy is collected in a photochromic heat exchange medium which flows to a generating system which converts the flow energy of the medium to mechanical energy driving a generator to produce electricity.
    Type: Grant
    Filed: June 21, 2002
    Date of Patent: April 22, 2003
    Inventors: Bruce Sangster, James D. Bond
  • Patent number: 6123868
    Abstract: A heat exchange medium is disclosed which utilizes a change in molecular configuration of photochromic compounds when they are exposed to light. Further, by the addition of the photochromic compound as a side chain to an organic polymer, the polymer can also be induced to change configuration and absorb larger amounts of heat.
    Type: Grant
    Filed: December 22, 1998
    Date of Patent: September 26, 2000
    Inventors: Bruce Sangster, James D. Bond
  • Patent number: 6051186
    Abstract: A container system is disclosed which effects sterilization of devices and objects by electric field and sterilizing media in substantially less time than that required by other sterilizing methods. The container system produces a totally enclosed and secure container.
    Type: Grant
    Filed: July 13, 1998
    Date of Patent: April 18, 2000
    Inventors: James D. Bond, Bruce Sangster
  • Patent number: 5750072
    Abstract: A sterilization process is disclosed which utilizes an oscillating magnetic field to control the state of free radicals in a sterilizing media and which synergetically induces a molecular structural change in the microorganism, thereby increasing the vulnerability of the microorganism to the sterilizing media. This process significantly enhances the efficiency of the sterilizing media and reduces the exposure time necessary for a lethal dose to harmful microorganisms. It is also disclosed that this process can be used directly on living human tissue or fragile medical devices or implants with no detrimental effects to the patient. It is also disclosed that this process can be used on the hands of health care or food service personnel to reduce the likelihood of nosocomial infection.
