  • Patent number: 9175400
    Abstract: A method is provided for depositing a whisker resistant tin-based coating layer on a surface of a copper substrate. The method is useful for preparing an article comprising a copper substrate having a surface; and a tin-based coating layer on the surface of the substrate, wherein the tin-based coating layer has a thickness between 0.5 micrometers and 1.5 micrometers and has a resistance to formation of copper-tin intermetallics, wherein said resistance to formation of copper-tin intermetallics is characterized in that, upon exposure of the article to at least seven heating and cooling cycles in which each cycle comprises subjecting the article to a temperature of at least 217° C. followed by cooling to a temperature between about 20° C. and about 28° C., there remains a region of the tin coating layer that is free of copper that is at least 0.25 micrometers thick.

  • Patent number: 8732583
    Abstract: A system and method are set forth for remotely controlling a presentation in a loop mode to allow the presentation to continue in the absence of a communication channel between the portable electronic device and remote presentation device. In particular, the portable electronic device can issue a command to the remote presentation device to present the presentation in loop mode so that a user of the portable electronic device can leave the vicinity of the remote presentation device (e.g. out of communication range) while the presentation plays in loop mode.

  • Publication number: 20140026468
    Abstract: A biological control is disclosed for termites, including subterranean termites such as C. formosanus, comprising a mixture of a chitin synthesis inhibitor such as lufenuron with a pathogen or opportunistic pathogen. The combination greatly enhances the effectiveness above that of the individual components. For example, P. aeruginosa is commonly found in association with termites, but it is not normally harmful to termites. However, in the presence of lufenuron, P. aeruginosa becomes an opportunistic pathogen that kills termites. As another example, B. thuringiensis, which otherwise has shown only limited effectiveness against termites, has greatly enhanced lethality in combination with lufenuron. In another aspect a termite toxicant is administered to termites in a clay-based bait. Clay acts as an attractant for subterranean termites such as C. formosanus, and a clay bait can increase a colony's consumption of a toxicant.

  • Patent number: 8581931
    Abstract: A system and method are set forth for remotely controlling a presentation from a portable electronic device so as to freeze a slide on a remote projector to permit searching for a desired slide on the portable electronic device and then continuing the presentation when searching is complete. In one embodiment, a switch is provided in a communication layer of a presentation application such that when the switch is turned off, communication is suspended between the portable electronic device and the projector, thereby permitting browsing on the portable electronic device without interrupting the presentation. When the switch is turned on the current slide information is transmitted from the portable electronic device to the projector.
