摘要： A light-emitting device comprises a light-emitting member, which comprises two electrodes, at least two organic electroluminescent (“EL”) materials disposed between the electrodes, a charge blocking material disposed between the electrodes, and at least one photoluminescent (“PL”) material. The light-emitting member emits electromagnetic (“EM”) radiation having a first spectrum in response to a voltage applied across the two electrodes. The PL material absorbs a portion of the EM radiation emitted by the light-emitting member and emits EM radiation having second spectrum different than the first spectrum. Each of the organic EL materials emits EM radiation having a wavelength range selected from the group consisting of blue and red wavelength ranges.

摘要： Organic light emitting devices are disclosed that use a micro electromechanical system (MEMS) structure to enable a pixel and pixel array wherein each pixel contains a MEMS and an OLED element. A MEMS structure is used for switching the OLED element. These OLED/MEMS pixels can be fabricated on flex circuit, silicon, as well as other inorganic materials. They can be fabricated in a large array for developing a 2-dimensional display application and each pixel can be addressed through conventional matrix scanning addressing scheme. The ability of fabricating these OLED/MEMS pixels on flexible organic substrates as well as other rigid substrates enables wider selection of substrate materials for use with different applications.

摘要： A current limiter device comprises at least two electrodes; an interlocked-array electrically conductive composite material disposed between the electrodes; interfaces disposed between the electrodes; an inhomogeneous distribution of resistance at the interfaces whereby, during a high current event, adiabatic resistive heating at the interfaces causes rapid thermal expansion and vaporization and physical separation at the interfaces; and means for exerting compressive pressure on the electrically conducting composite material. The interlocked-array electrically conductive composite material comprises an interlocked-array of spaced apart discrete regions of at least one insulating flexible material and at least one electrically conductive composite material. A method for forming the interlocked-array electrically conductive composite material structure is also set forth by the invention.

摘要： A current limiting system for a circuit limits current flow through the system. The current limiting system comprises at least one main switch comprising first and second main switch contacts and a contactor connecting the first and second main switch contacts; at least one current limiting device and at least one solid-state switch, which are mechanically unconnected to the main switch, and the at least one current limiting device and least one solid-state switch are arranged in series on a series side of the circuit; the at least one main switch is on a main switch side of the circuit arranged in parallel with the series side; a control that senses a predetermined condition of the circuit, and operably connected with the at least one solid state switch to open and it. Under normal operating conditions, most current flows through the at least one main switch side. When the predetermined condition causes the main switch to open, and the resistance increases in a main switch side. Thus, current flows to the series side of the circuit side. The current limiting device then switches its state from a low resistance to a high resistance state to limit the current passing through the current limiting system, where the control has sensed a predetermined condition and signals the solid-state switch to open, thereby interrupting current flow through of the current limiting system.
