  • Publication number: 20200154900
    Abstract: The present invention introduces a “non-contacting” or tent-like comforter, which has one or more air gaps between parts of the user's body and the comforter portions right above said parts of the user's body when the comforter is in use, and at least part of the weight of the comforter body is not directly supported by the user or the bed. The invention also introduces a process that creates one or more air gaps between parts of the user's body and the comforter portions right above said parts of the user's body, and at least part of the weight of the comforter body is not directly supported by the user or the bed.

  • Publication number: 20110251109
    Abstract: Fluidic methods and devices for conducting parallel chemical reactions are disclosed. The methods are based on the use of in situ photogenerated reagents such as photogenerated acids, photogenerated bases, or any other suitable chemical compounds that produce active reagents upon light radiation. The present invention describes devices and methods for performing a large number of parallel chemical reactions without the use of a large number of valves, pumps, and other complicated fluidic components. The present invention provides microfluidic devices that contain a plurality of microscopic vessels for carrying out discrete chemical reactions.

  • Patent number: 6562549
    Abstract: A method for adjusting out of tolerance critical dimensions of an under processed photomask to be within predetermined defined limits after the photosensistive resist material has been removed from the exposed photomask. The method includes measuring the critical dimensions of the opaque material of the under processed photomask after the photosensitive resist material has been removed, and exposing the photomask to electrified plasma gases for removing excess opaque material without degrading the reflectivity of the photomask beyond specified limits.
