20100233459 | METHOD FOR THE PRODUCTION OF A TEXTILE-REINFORCED RIGID FOAM SUPPORT ELEMENT, AND RIGID FOAM SUPPORT ELEMENT - The fabric-reinforced rigid foam supporting element claimed having a total thickness of <10 mm is characterized in that it has been produced completely by machine. As a result of the specific features and the preferred production process, supporting elements which have a low thickness and do not differ in terms of their stiffness and strength from supporting elements having thicknesses above 10 mm are obtained. They are therefore outstandingly suitable as insulation materials in building and construction, in particular for constructions, and also for thermal and and/or acoustic insulation. | 09-16-2010 |

20100005426 | Method for Identifying Phone Numbers and Alphanumeric Sequences - A method and system provides the ability to identify phone numbers and alphanumeric sequences in a text source such as a web page and format them and/or convert them into usable information. According to one aspect, the invention automatically identifies and formats phone numbers in web pages so that they can be automatically dialed using VoIP or PSTN phone services. According to other aspects, the formatted phone number can be provided to any network voice applications, such as voice-over IP (VOIP) solutions, voice chat, voice IM, and wireless, WiFi, and WiMax connections. According to additional aspects, the invention can be integrated with internet browsing applications to allow automatic dialing of phone numbers over VOIP services or PSTN services. According to still other aspects, the invention allows technical support, electronic commerce, customer support numbers, phone numbers for product ordering, etc., on company web pages to be identified and dialed with a mouse click. According to yet other aspects, a search engine provider using the invention can charge an advertiser for phone calls placed to the advertiser, which are far more valuable than “clicks” on advertiser links, thereby reducing the “click fraud” problem afflicting current search engine technology. | 01-07-2010 |
