20090203331 | METHOD AND APPARATUS FOR ACCESSING A NETWORK COMPUTER TO ESTABLISH A PUSH-TO-TALK SESSION - A wireless phone user registered for push-to-talk (PTT) services desires a push-to-talk session with a party on a network computer accessible via a public data network (like the Internet) that is not registered with any PTT service. The registered user enters a unique identifier, as a destination address for such computer, and a PTT server uses the unique identifier to query a Directory Service available on the public data network to obtain a PTT address for the destination computer. The PTT server then forwards or proxies the PTT request to the destination computer. As a result, the number of push-to-talk destinations available to the wireless phone user is expanded to include any number of push-to-talk enabled computers available on the Internet that are known to the Directory Service. | 08-13-2009 |

20100104203 | Method and Apparatus for Acquisition, Compression, and Characterization of Spatiotemporal Signals - The present invention provides methods and apparatus for acquisition, compression, and characterization of spatiotemporal signals. In one aspect, the invention assesses self-similarity over the entire length of a spatiotemporal signal, as well as on a moving attention window, to provide cost effective measurement and quantification of dynamic processes. The invention also provides methods and apparatus for measuring self-similarity in spatiotemporal signals to characterize, adaptively control acquisition and/or storage, and assign meta-data for further detail processing. In some embodiments, the invention provides for an apparatus adapted for the characterization of biological units, and methods by which attributes of the biological units can be monitored in response to the addition or removal of manipulations, e.g., treatments. The attributes of biological units can be used to characterize the effects of the abovementioned manipulations or treatments as well as to identify genes or proteins responsible for, or contributing to, these effects. | 04-29-2010 |

20130339471 | SYSTEM AND METHOD FOR QUICK-LINKING USER INTERFACE JOBS ACROSS SERVICES BASED ON SYSTEM IMPLEMENTATION INFORMATION - Systems and methods are provided for a data management virtualization display. A set of services is stored that includes a set of user interfaces. Each service can communicate with the remaining services using a shared services cache. A request is received to perform a data management virtualization job that, without knowledge of a profile associated with the data management virtualization system, the set of subsystems, or both, would require a user of the data management virtualization system to manually navigate through a sequence of webpages across two or more services in the set of services. A quick link for the data management virtualization job is defined based on the profile associated with the data management virtualization system, the set of subsystems, or both, using the shared services cache, wherein the quick link eliminates one or more of the manual navigations of the data management virtualization job. | 12-19-2013 |
