  • Patent number: 8691198
    Abstract: Compounds derived from acetone are provided. Particularly, the compounds are derivatives of hydroxyacetone, including dimers of both 1-hydroxyacetone and 1,3-dihydroxyacetone. The hydroxy moieties on the core hydroxyacetone molecule serves as an attachment point for a variety of moieties (e.g., ethers, esters, phosphorous containing, or nitrogen containing) that are selected to provide the compound with a particular property. Applications of the compounds include plasticizers, supersurfactants, and additives for health care products, such as shampoo and perfume.

  • Publication number: 20140037572
    Abstract: A compound includes a boron atom attached to at least one C8-C26 fatty acid residue having at least one C?C moiety. Such compounds are polymerizable through the at least one C?C moiety. Polymers thus formed exhibit anti-fouling properties when used as coatings.

  • Patent number: 7046182
    Abstract: A DAC architecture is provided which is monotonic in operation despite any mismatches in the components. The architecture is a segmented architecture and hence it is area efficient. This is achieved by effecting a generation of analog voltages by driving current sources to resistors in response to digital input. In a preferred embodiment, the invention provides a resistor string coupled between output and vref-, and set of current sources. The current sources are switched to nodes between resistors to generate voltages at the output.

  • Patent number: 5894310
    Abstract: Shapes and solids modeled by a 3-D computer graphics system have "intelligence", i.e., the shape typically includes a wide variety of characteristics in addition to geometric (e.g., size and positional) information. These additional characteristics permit a user to manipulate 3-D shapes intuitively using a graphical user interface providing "drag and drop" capabilities--reducing the number of factors the user must worry about, saving a lot of time and user frustration, and allowing even non-technical, unskilled users to rapidly and efficiently create impressive images. A component-based architecture may expose any of multiple, alternate representations of the same shape depending on the particular need or application to provide an "intelligent load" that is especially powerful and advantageous in remote interactive imaging applications (e.g., via the Internet) where data transfer and/or load times must be minimized.

  • Patent number: 5039753
    Abstract: Polymers comprising a polymer backbone having pendant or terminal betadiketone groups which contain at least one trifluoromethyl group. The betadiketone groups may be selected from trifluorocetoacetate groups (general formula I); ##STR1## hexafluoroacetylacetone groups (general formula II); ##STR2## or trifluoro-2,4-pentanedione groups (general formula III); ##STR3## where indicates the polymer backbone, R is an alkyl, substituted alkyl, aryl or substituted aryl group and R.sup.1 is hydrogen, alkyl or substituted alkyl. Neither the R group nor the R.sup.1 group should contain any group which is sufficiently basic to initiate cyanoacrylate polymerization or any group sufficiently acidic to interfere with chain transfer.
