  • Patent number: 11934248
    Abstract: Power management in a computing device. A driver is registered with an operating system (OS) executing on the computing device to receive information about a position of a user interface control. If the user interface control is moved, the driver receives a notification of the user interface control position and determines a power management intervention based on the position The driver transmits the power management intervention to power control circuitry which sets a power setting of the computing device based on the intervention.

  • Patent number: 8522829
    Abstract: An insulated article having a first insulation region comprising a first polymeric material and first hollow ceramic microspheres and a second insulation region comprising a second polymeric material and second hollow ceramic microspheres. The first insulation region has a thermal conductivity that is no greater than the thermal conductivity of the first polymeric material and a volumetric heat capacity in a range of 60% to 90% of the volumetric heat capacity of the first polymeric material. The second insulation region has a thermal conductivity that is no greater than 90% of the thermal conductivity of the second polymeric material and a volumetric heat capacity that is less than 60% of the volumetric heat capacity of the second polymeric material. A method for making a composition for insulating an article is also described.

  • Publication number: 20110027592
    Abstract: A binder or sizing composition that is provided that demonstrates improved hydrolytic stability of the bond between a SiO containing substrate, such as glass, and a matrix polymer, such as polypropylene, which is especially useful in reinforced plastics. A water-based composition is provided that contains at least one amino-functional coupling agent, and acid or anhydride modified polyolefin, and an epoxy functional compound. This composition is useful as a glass binder or sizing to provide a strong bond between glass and a polymer.

  • Patent number: 6906009
    Abstract: The present invention provides a drilling fluid composition and a method of drilling comprising a drilling fluid, which may be oil- or water-based, and a composite microsphere component. The invention drilling fluid composition advantageously reduces the density of a conventional fluid, reduces costs associated with pumping and overcomes problems associated with conventional gas-injection processes. The invention uses conventional drilling and pumping equipment, requires no sea-floor based pumps and may be easily pressure-controlled to maintain the pressure of the fluid.
