  • Two-track surface acoustic wave structure without internal pads
    Patent number: 8134426
    Abstract: The present disclosure relates to a two-track surface acoustic wave (SAW) device that has a reduced size compared to a traditional two-track SAW device by eliminating an internal ground connection node of the traditional two-track SAW device. The internal ground connection node is eliminated by coupling an internal ground interconnection to an external ground connection node through an interconnecting ground grating, which is part of one of two SAW tracks of the two-track SAW device. The internal ground interconnection is located in an internal region of the two-track SAW device that is defined by the two SAW tracks and by two electrical interconnections between the two SAW tracks.

  • Method to improve diversity gain in a cooperative spectrum sensing network
    Patent number: 8135424
    Abstract: A cooperative sensing technique (300) operates by selecting a group of subscribers (302) from a secondary system, measuring a cooperative sensing metric (306) and then using the metric to identify an achievable spatial diversity gain for the group of selected subscribers (308). Once an achievable spatial diversity gain is determined for the group (308/412), it is compared to a required spatial diversity gain (310), and if the condition is met at (310), the validated group can begin spectrum sensing (314) to identify a vacant/suitable channel for operation. If the achievable spatial diversity gain is insufficient, then a new group of users is selected (312) within the secondary system and the process repeats itself.

  • Processor for fast contextual matching
    Patent number: 8135717
    Abstract: Words having selected characteristics in a corpus of documents are found using a data processor arranged to execute queries. Memory stores an index structure in which entries in the index structure map words and marks for words having the selected characteristics to locations within documents in the corpus. Entries in the index structure represent words and other entries represent marks with the location information of a marked word. The entries for the marks can be tokens coalesced with prefixes of respective marked words or adjacent. A query processor forms a modified query by adding a mark for a word to the query. The processor executes the modified query.

  • SYSTEMS AND METHODS FOR PROVIDING ADVERTISEMENTS TO USER DEVICES USING AN ADVERTISEMENT GATEWAY
    Publication number: 20120059696
    Abstract: An advertisement gateway that provides an interface for multiple user devices and multiple advertisement sources to communicate is presented. The advertisement gateway is capable of translating advertisement requests from a user device in a particular format into another format that is compatible with an advertisement source. Conversely, the advertisement gateway can translate advertisement responses from an advertisement source in a particular format into another format that is compatible with the requesting device. In this manner, the advertisers only have to develop an advertisement using a single protocol and format (i.e., the protocol to communicate with the advertisement source) and still be able to provide their advertisements to a wide variety of user devices.
