A private document delivery system and method includes a sending computer configured to transmit an electronic document over a computer network, a dynamically established encrypted line to traverse the computer network from a receiving computer to the sending computer where the delivery address of the receiving computer is resolved at the time of transmission of the private message such that no third parties to the message receive a permanent copy of the message. The system and method also includes a signaling mechanism configured to notify the receiving computer that the electronic document is waiting for delivery. The system and method includes a verification agent configured to verify the receiving computer's identity with a protocol specified by the sending computer and to provide access instructions to the receiving computer with which the receiving computer locates the sending computer via the dynamically established encrypted line and receives the transmitted electronic document.
摘要:
A collision detection and data synchronization mechanism operates to expand the speed and capability of distributed applications. The execution environment employs collision detection and data synchronization to distribute data objects to appropriate network nodes to support local processing. The collision detection and data synchronization mechanism defines the set of processes and algorithms used to track distributed data objects and to manage changes to the distributed objects throughout a network of intelligent computing devices. Data and code are distributed to local computing devices necessitating tracking and synchronizing updates. The system and method ensures that data updates received during the course of a local transaction do not unwillingly affect the results of other transactions by notifying the local computing devices of changes to the data that are subject of the transaction. These conflicts are then resolved in the applications, and notification of the resolution is sent to the remaining intelligent computing devices.

A system for storing, managing, and accessing information on a network by providing an interface between a social network and a content network includes an applications platform. The system provides messaging and social networking facility incorporating enhanced instant messaging, file synchronization, network presence, interactive chat capabilities, text messaging, voice and video messaging, blogging, and email. The system includes a viewer, an indexing facility, and a storage facility. The viewer enables users to traverse content and provides services based upon context of time, place, structure, node, and observed user behavior. The viewer provides a means for users to interact with information on the network and services to manipulate information and transact activities. The indexing facility manages the structure of the network and tracks attributes and controlled vocabularies. The indexing facility supports navigation across the structure and resolves the logical index to a physical storage location. The storage facility provides physical persistence for an information component.
摘要:
A variable geometry coil system includes a single fixed horizontal coil and a vertically oriented pair of movable coils interconnected through an electronic matrix to allow for a multi-mode system which enables either the vertical pair or the horizontal coil to function alone or to enable a quadrature combination of the coils for optimum signal performance. The vertical coil pair includes two matched coils which are loaded to reduce their tuning sharpness so as to eliminate the need for clinical tuning prior to utilization. Signal losses incurred by the Q reduction are compensated for by including an integrated preamplifier at the signal output.

A reflectometer tuning unit for a magnetic resonance imaging (MRI) system, provided for the standing wave voltage adjustment of various MRI receive coil units, and which is also capable of detection of various open/short fault conditions in the MRI receive coil unit or the coaxial cable connected to the MRI receive coil unit. The reflectometer tuning unit comprises an oscillator, a directional coupler, and a measuring system. The oscillator produces an output signal having its frequency tuned to the Larmor frequency of the magnetic resonance imaging system. The directional coupler has OUT, IN and CPL ports. The output of the oscillator is connected to the OUT port, and selected impedances, and later the receive coil unit, are connected to the IN port. The directional coupler produces an output signal at the CPL port which is proportional to the port of energy reflected back from the IN port to the OUT port, which is also proportional to the impedance mismatch presented by the impedance at the IN port. The measuring system is connected to the CPL port of the directional coupler, and measures the magnitude of the output signal at the CPL port. The measuring system of the reflectometer tuning unit includes a rectifying detector connected to the CPL port of the directional coupler, which provides a DC voltage output. An amplifier is connected to the output of the rectifying detector, and an LED display is connected to the output of the amplifier.
