    • It is disclosed herein a breakthrough concept for in-space propulsion for future Air Force, NASA and commercial systems. The invention combines the fields of micro-electrical-mechanical (MEMs) devices, optical physics, and nonequilibrium plasmadynamics to reduce dramatically the size of electric thrusters by 1-2 orders of magnitude, which when coupled with electrodeless operation and high thruster efficiency, will enable scalable, low-cost, long-life distributable propulsion for control of microsats, nanosats, and space structures. The concept is scalable from power levels of 1 W to tens of kilowatts with thrust efficiency exceeding 60%. Ultimate specific impulse would be 500 seconds with helium, with lower values for heavier gases.

    • The invention provides microchannel lasers having a microplasma gain medium. Lasers of the invention can be formed in semiconductor materials, and can also be formed in polymer materials. In a microlaser of the invention, high density plasmas are produced in microchannels. The microplasma acts as a gain medium with the electrodes sustaining the plasma in the microchannel. Reflectors are used with the microchannel for obtaining optical feedback to obtain lasing in the microplasma gain medium in devices of the invention for a wide range of atomic and molecular species. Several atomic and molecular gain media will produce sufficiently high gain coefficients that reflectors (mirrors) are not necessary. Microlasers of the invention are based on microplasma generation in channels of various geometries. Preferred embodiment microlaser designs can be fabricated in semiconductor materials, such as Si wafers, by standard photolithographic techniques, or in polymers by replica molding.

    • A session integration method is provided for integrating a first session between a first entity and a third entity and a second session between a second entity and the third entity in a session-based service environment. The first entity receives a REFER message including dialog information from the second entity, and sends a response message to the received REFER message to the second entity. When header information included in the received REFER message indicates an INVITE message and the dialog information is related to the first entity, the first entity generates a Re-INVITE message and sends the generated Re-INVITE message to an address of a target which is subject to session integration. The address is included in the header information and corresponds to the third entity. The first entity updates the first session into an integrated session with the third entity.
