摘要： The present invention provides co-doped zinc oxide to flat panel, light emissive display devices and vacuum microelectronic devices to improve their efficiency and lifetime. This material has a low growth temperature and is compatible with metal oxide semiconductor (MOS) processing technology. It is tranparent, chemically stable and has a low work function, which result in many advantages when being used as the cathode for the aforementioned devices. In one embodiment of the emissive display device, an organic light diode (OLED) display has a high work function metal anode, such as platinum (Pt), gold (Au) or nickel (Ni) and a low work function co-doped zinc oxide cathode. Because of the energy level alignment provided by these two materials, the potential energy barriers to injection of electrons from the cathode and holes from the anode into the organic emissive medium are minimized so the display device operates more efficiently.

摘要： Light emitters are formed and patterned on an electrode for an organic light-emitting device by electrochemically polymerizing a monomer across the full length of the electrode. A second electrode is deposited so to define a pixel region between mutually aligned portions of the two electrodes. Electroluminescence of the emitter occurs when a voltage is applied across the electrodes of the device.

摘要： Disclosed is an apparatus for depositing a layer of a material on a substrate and annealing the deposited layer, including a Q-switched Nd: YAG laser for providing a coherent light output. An up collimator is situated in the path of the coherent light output to increase the cross sectional area of the output, while a beam divider separates the output into first and second coherent beams. First and second lenses are adjustably positioned in the paths of the beams to focus the first beam on a source of the material and the second beam on the substrate. First and second x-y scanners are provided for scanning the first and second beams. A vacuum chamber includes a connection for a vacuum source and windows to admit the first and second beams into the chamber. A source support positions a source of the material within the chamber in the path of the first beam and a substrate support positions the substrate in the path of the second beam and at least 45.degree. away from the normal to the surface of the source.

摘要： The present invention is an improved energy harvester or generator based on a yoked magnet array design based on a plurality of magnets arranged into at least two spaced apart linear or circular magnet arrays. The spaced apart magnet arrays are juxtaposed with each magnet in one array attractively interacting with the corresponding magnet in the other array across a small gap. The magnetic flux across the gap is further enhanced by having adjacent magnets in each array having alternate magnetic orientation and by providing a magnetic yoke of magnetically permeable material for the magnet ends of each array that do not face the gap. The gap is provided to allow a conductor in the form of a coil fit between the magnets. Relative motion between the coil and the magnets results in maximal generation of electrical power by the coil.

摘要： A mechanical translator includes at least one magnet that is disposed on a substrate to carry a load and has a magnetic axis generally transverse to the substrate, establishing a magnetic field with maximum external density adjacent the substrate. An ultra low friction interface is obtained with ferrofluid bearings, such as a light mineral oil medium mixed with isoparaffinic acid, which establish a critical angle of displacement from a horizontal static position of less than 1 degree, and preferably less than 10 minutes. A controller of magnetic material can be placed on the opposite side of the substrate to control the movement of the magnets.

摘要： An electrical generator has a plurality of spaced magnets that move together relative to at least one coil to generate an electrical signal in the coils. Equal numbers of magnets and coils, with equal lengths and spacings between them, are preferably employed. Significant enhancements in power output are achieved by orienting successive magnets in magnetic opposition to each other, so that the magnetic fields from successive magnets along the axis of movement substantially cancel each other at locations between the magnets.

摘要： A method is provided for depositing a uniform thin film on a substrate using laser ablation of a target material in a deposition chamber. The laser beam may be pulsed and focused to strike the target along a line to produce a broad plume of ablated material expanding in a propagation direction outward from the target. The plane of the substrate deposition surface is oriented generally parallel to the propagation direction of the plume of ablated material. The deposition chamber includes a low background pressure of inert or reactive gas to facilitate lateral diffusion of ablated atoms, ions, and molecules to be deposited on the substrate surface. Particles ejected from the target material, which have trajectories generally parallel to the propagation direction of the plume, are too heavy to have significant lateral diffusion and have little chance of lodging on the deposition surface. The substrate may be rotated about an axis perpendicular to the deposition surface (and generally perpendicular to the propagation direction of the plume) to provide uniform deposition over the entire surface. The method may also be used to deposit thin films on both sides of a substrate simultaneously, and on multiple substrates by stacking them in the plume in space-apart orientation.

摘要： A dynamic magnet system, particularly useful for electrical generation, employs multiple magnets in polar opposition to each other for individual movement relative to a support structure. The magnets have a critical angle of displacement from a horizontal static position of less than 1 degree, with at least some of the magnets having mutually different properties. With different magnetic strengths, a greater movement is produced for both magnets in response to movements of the support structure, for particular ranges of magnetic strength ratios, than would be the case with equal magnets. The magnet movement can be translated into an electrical signal to power an operating system. Ultra low friction ferrofluid bearings can be used to establish static coefficients of friction between the magnets and support structure less than 0.02, enabling useful power generation from only slight movements of the support structure.

摘要： An autonomous power source comprises a power harvester mounted on a movable structure. The power harvester includes a coil, a magnet, and a low-friction ferrofluidic bearing in contact with the magnet, arranged such that the magnet and coil move with respect to each other when the structure is in motion such that an electrical current is produced in the coil. This current is converted to power and stored in an energy storage system and is thus available to power electronic circuitry. The magnet and bearing are preferably enclosed within a closed linear or circular tube, with the coil mounted around the exterior of the tube. The power harvester and battery are combined with one or more sensors and a wireless transmitter to form a tire pressure monitoring system.
