  • Publication number: 20220047732
    Abstract: A system and method that include using biophotonic and/or phononic systems for deactivating viruses, bacteria, and other pathogens that may be present on people, their clothing, or other surfaces. Biophotonic refers to the use of photons in specific wavelengths of the FAR Ultraviolet C radiation and/or FAR Infrared C radiation to affect the interior structure and chemistry of bacteria and viruses to degrade them and render them harmless. The infrared radiation may also provide a phononic effect that degrades the physical conditions of the cell or virus sufficiently to disrupt the cellular machinery, deactivating the virus. Furthermore, a higher temperature Inside the UVIR system makes negligible the rate of propagation of the Virus. The system of the present invention is operable to use electromagnetic radiation to disinfect the exterior surfaces of living mammal animals without harming the animal's tissue, but still effective to degrade microbe and sanitize the exterior surfaces.

  • Publication number: 20210369879
    Abstract: A system and method that include using biophotonic and/or phononic systems for deactivating viruses, bacteria, and other pathogens that may be present on people, their clothing, or other surfaces. Biophotonic refers to the use of photons in specific wavelengths of the FAR—Ultraviolet C radiation and/or FAR—Infrared C radiation to affect the interior structure and chemistry of bacteria and viruses to degrade them and render them harmless. The infrared radiation may also provide a phononic effect that degrades the physical conditions of the cell or virus sufficiently to disrupt the cellular machinery, deactivating the virus. Furthermore, a higher temperature Inside the UVIR system makes negligible the rate of propagation of the Virus.

  • Publication number: 20180290473
    Abstract: We describe a print removal device for removing print from a print-carrying medium. In embodiments the print removal device comprises: a feed system for receiving the print-carrying medium and guiding the print-carrying medium through the print removal device; and a system to remove the print from the print-carrying medium, in particular a laser light source for providing a controllable laser light beam to remove the print from the print-carrying medium. Previously used paper for “unprinting” may not be flat and well-behaved, and access may be needed to the full width of the paper creating a section where physical guiding is compromised, and thus the feed system comprises a media guide with an inflection configured to bias the print-carrying medium towards a face of the print-carrying medium which faces away from the laser light source when the print-carrying medium is guided through the print removal device also having the benefit to control the media more accurately to the preferred optical focus plane.

  • Patent number: 9552459
    Abstract: A method, computing device and computer program product are provided in order to implement a test plan in an efficient manner. In the context of a method, a plurality of test messages from each of a plurality of different source systems are stored. The plurality of test messages may include test messages to be captured in an electronic health record. The method constructs a test plan. The test plan identifies an end point. The test plan also includes one or more test messages that have been previously stored and respective anticipated outcomes at the end point following transmission of the test messages. The method also includes transmitting the test messages of the test plan and receiving feedback regarding the outcome following transmission of the test messages of the test plan to the end point. The method also includes determining whether the test plan was successfully executed based upon the feedback.

  • Publication number: 20040060161
    Abstract: The present invention is directed to various methods of forming a heart valve stent. In one embodiment, the method comprises providing a cylinder of material, the cylinder having an outside diameter and an inside diameter, the inside diameter having a first dimension, forming a plurality of stent posts on an end of the cylinder, and increasing the inside diameter of the cylinder of material to a second dimension, the second dimension being greater than the first dimension.
