Call origination by an application server in an internet protogol multimedia core network subsystem

A system and method for call origination by an application server in an internet protocol multimedia core network subsystem includes a first step of providing a public user identity for a user. A next step includes storing a service parameter in a service profile of the user, the service parameter indicating whether to allow / disallow the application server to initiate call requests on behalf of the public user identity. If the service parameter allows the application server to initiate call requests, the system unblocks calls originated by the application server on behalf of the user. If the service parameter disallows the application server to initiate call requests, the system blocks calls originated by the application server on behalf of the user.

Inter-site call routing and roaming support

A method (600,700) and apparatus (800) are arranged and operate for facilitating call routing between sites in an enterprise connected by a private IP network (130). A range of identifiers (220-223) served by IP PBXs (120-123) in the enterprise may be registered with a SIP registrar (212) of an inter-site router (210). Call requests to a communication unit (350) outside the home site are routed to the SIP registrar. A site identifier associated with the destination IP PBX allows the call to be completed by the SIP Proxy or the IP PBX where the call was received. When no private IP network is available, a roaming CU registers with a cellular proxy in the visited network. Calls are routed by when an HLR (340) associated with the CU obtains the roaming number from the cellular proxy (330) in the visited site. The MSC completes the call to the visited IP PBX using the roaming number and a local SIP registrar 440 forwards the call to the CU.

Mass spectrometry system for continuous control of environment

A mass spectrometry system for continuous control of environment based on the use of an aerosol TOF MS that provides operation with a high duty cycle of up to 98% and can be realized in the form of a mobile unit having a data acquisition and analysis system with three levels of data correlation on the basis of constant interaction between various actuating mechanisms of the system via a central processing unit. The TOF MS is based on the use of quadrupole lenses with angular gradient of the electrostatic field. On the entrance side, the TOF MS contains an ion-optic system that is used for focusing, aligning, and time-modulating the ionized flow of particles and a deflector modulator that provides alternating deflections of the flow of particles between two positions for aligning the flow with two inlet openings into the TOF MS. As a result, two independently analyzed discrete flows of particles pass through the ion mass separation chamber of the TOF MS without interference with each other. The charged particles fly in direct and return paths along helical trajectories which extend the length of the flight time. The time of the collision and the magnitude of the collision pulse will contain information about the M / Z ratio for the particles being registered. Multiplication of a single flow of particles into a plurality of independent and spatially separated flows propagating in one chamber increases efficiency of the TOF MS and makes it possible to use it in continuous and high-duty applications with the duty cycle as high as 98%, which is unattainable with any known device of this class. The system can be mounted either on an underwater and ground vehicle, or on an aircraft.
