  • Patent number: 10023896
    Abstract: A system for checking interior air contamination, the system including a sealed device including twin ports, a sampling device including a pump to extract at least some of the air from the interior of the sealed device, and a microbial detect to determine if the air contains contaminants. The twin ports are removably engageable with the sampling device to allow a circuit of air between the pump unit and the sealed device, such that air extracted from one of the twin ports by the pump is returned to the other of the twin ports, allowing no escape of the air to the environment. The sealed device is sealed to prevent, except through the twin ports, exterior air to flow into the sealed device and the air from the interior to flow out.

  • Patent number: 9427400
    Abstract: The present invention provides improved intravaginal drug delivery devices, i.e., intravaginal rings, useful for the prophylactic administration of an antimicrobial compound, e.g., Dapivirine, to a human. The intravaginal rings of the invention address previous stability issues by utilizing a platinum catalyst (e.g., in the form of a platinum-siloxane complex) for the cross-linking reaction. The vaginal rings surprisingly achieve relatively high and steady release rates in vivo with a matrix ring containing a relatively small loading dose. While the matrix rings of the present invention have in vivo the steady release rates associated with reservoir rings, they are easier and less expensive to manufacture. The present invention also provides methods of blocking DNA polymerization by an HIV reverse transcriptase enzyme, methods of preventing HIV infection in a female human, methods of treating HIV infection in a female human, and methods of preparing platinum-catalyzed intravaginal rings.

  • Patent number: 9033901
    Abstract: A measuring device to aid mattress selection has an upstanding frame with a plurality of vertically space-apart horizontal illuminated strips. A camera mounted in front of the frame takes front view and side view images of a person standing in front of the illuminated strips. These images are delivered to an associated computer having means to determine the body mass distribution and the spine curvature of the person based on the images of the strips taken by the camera and in particular based on those portions of the image of the illuminated strips blocked by the person standing in front of the illuminated strips. This information can then be used to aid in appropriate mattress selection for the person.
