  • Publication number: 20110271202
    Abstract: A server application for an instant messaging service opens a first connection with a first client application executing on a device, after receiving a login from the first client application. Next the server application opens a second connection with a second client application, after receiving the same login from the second client application. Then the server application receives an instant message associated with the login and determines whether the first client application is in a network idle state following a period of idle time. If the first client application is in the network idle state, the server application causes a notification as to the receipt of the instant message to be displayed on a user interface for the second client application. The displayed notification might also be accompanied by an aural notification or a haptic alert.

  • Publication number: 20110270934
    Abstract: A server application for an instant messaging service opens a first connection with a first client application executing on a device, after receiving a login from the first client application. Next the server application opens a second connection with a second client application, after receiving the same login from the second client application. Then the server application transfers state from the first client application to the second client application without terminating the first connection, where state includes an instant message which is associated with the login and where the instant message was received between the time the first connection was opened and the time the second connection was opened. State can also include other unread instant messages, as well as window positions and configurations for a user interface supported by both client applications.

  • Publication number: 20110043627
    Abstract: An exemplary system and method are disclosed for providing a combined video stream with geospatial information. Embodiments use a visualization tool to synchronize information in a virtual camera with attributes, such as video frames, from a physical camera. Once the camera position information is supplied to the visualization tool, the visualization tool retrieves geospatial data, such as terrain features, man made features, and time sensitive event data, and transforms the camera position information into a coordinate system of the virtual camera. The visualization tool uses the coordinate system of the virtual camera to generate geospatial snapshots. Embodiments use locative video software to combine the video frames from the physical camera with the geospatial snapshots from the virtual camera to generate a combined video stream, which provides a single view of multiple types of data to enhance an operator's ability to conduct surveillance and analysis missions.

  • Patent number: 7616012
    Abstract: Embodiments of the invention can provide systems, methods, and apparatus for providing a capacitance paddle for measuring capacitance in a stator component such as a stator bar. In one embodiment, a system for measuring capacitance can include an output device operable to measure capacitance in an object. Furthermore, the system can include at least three contacts operable to mount to the object to be sensed. In addition, the system can include at least one conductive material operable to mount to the object to be sensed. Moreover, the system can include a compressible material adjacent to at least some of the at least three contacts and the at least one conductive material, wherein the compressible material can be compressed to permit the contacts to simultaneously contact the object to be sensed, and wherein the output device can output a measure of capacitance associated with the object.

  • Publication number: 20090248591
    Abstract: A process to create a fungible global standard for diamonds and gemstones. The process involves grouping diamonds in an investment standard according to their gemological, proportional, optical and light behavior characteristics. Diamonds that conform to the investment grade standard are interchangeable within a specific size range according to an equivalent monetary bundling process. Diamonds subjected to the standard conform to a holistic set of gemological, proportional, optical and light characteristic requirements that enables diamonds to be classified into a extraordinarily homogeneous, visually indistinguishable and highly fungible group which can be used to create baskets of diamonds to form an index/benchmark for diamond pricing, financial instruments, and a standard that can be used for certifying diamonds as investment grade to insure quality.
