摘要： The present invention provides an optical recording medium in which the spot size of incident laser beam, focused on the medium by a far-field optic system characterized by λ and NA, is further reduced and maintained below the diffraction-limited size by means of material characteristics of the medium while reproducing from and recording on the information layer of the recording medium, thus making it possible to record and reproduce a high density of information exceeding the resolution limit of the optic system.A high density optical recording medium according to the present invention adopts a combination of two different super-resolution layers of mutually complementary optical characteristics with increasing light power.The combination of two super-resolution layers is made in either of two different types: for one type, each of the two super-resolution layers, having a respective threshold light intensity (or temperature) for the onset of change in optical transmittance, produces an increasing spot size of the transmitted beam with increasing light power once a respective threshold light intensity (or temperature) is exceeded, and for the other type, one layer produces an increasing spot size of the transmitted beam with increasing light power whereas the other layer exhibits a reverse trend.

摘要： A system and a method for establishing a group messaging session in consideration of a group policy in a communication system. A transmitter-side terminal stores information on a group policy in a group information storage unit, and transmits, to a server, an INVITE message requiring application of the group policy to generation of a group messaging session. The server receives the INVITE message, recognizes that the group policy should be applied to the generation of the group messaging session, and acquires the information on the group policy from the group information storage unit. The server transmits the INVITE message including the acquired group policy information to a receiver-side terminal that is invited to participate in the group session, and receives a response from the receiver-side terminal.

摘要： Microstructured, irregular surfaces pose special challenges but coatings of the invention can uniformly coat irregular and microstructured surfaces with one or more thin layers of phosphor. Preferred embodiment coatings are used in microcavity plasma devices and the substrate is, for example, a device electrode with a patterned and microstructured dielectric surface. A method for forming a thin encapsulated phosphor coating of the invention applies a uniform paste of metal or polymer layer to the substrate. In another embodiment, a low temperature melting point metal is deposited on the substrate. Polymer particles are deposited on a metal layer, or a mixture of a phosphor particles and a solvent are deposited onto the uniform glass, metal or polymer layer. Sequential soft and hard baking with temperatures controlled to drive off the solvent will then soften or melt the lowest melting point constituents of the glass, metal or polymer layer, partially or fully embed the phosphor particles into glass, polymer, or metal layers, which partially or fully encapsulate the phosphor particles and/or serve to anchor the particles to a surface.

摘要： 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.

摘要： 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.

摘要： The cavity 102 defines an empty volume formed in the insulator 108 has its walls defined by the insulator 108 and may extend through either (or both) the first electrode 106 or the second electrode 104, in which case the first electrode and/or second electrode also define the walls of the cavity 102. The cavity 102 is preferably cylindrical and has a diameter of 0.1 μm-1 mm. More preferably, the diameter ranges from 0.1 μm-500 μm, 1 μm-100 μm, or 100 μm-500 μm. The cavity 102 will be filled with a gas that contacts the cavity walls, fills the entire cavity 102 and is selected for its breakdown voltage or light emission properties at breakdown. Light is produced when the voltage difference between the first electrode 106 and the second electrode 104 creates an electric field sufficiently large to electrically break down the gas (nominally about 104 V-cm). This light escapes from the microcavity 102 through at least one end of the cavity 102.
