Abstract: 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.

Abstract: The present invention relates to a novel zinc oxide thin film having hydrogen (H) and gallium (Ga) dopants. Advantageously, the activation temperature is low. The co-doped zinc oxide is highly conductive, transparent, chemically stable, easily deposited on a variety of substrates, including flexible or plastic substrates, and is well suited for electrical or optical applications. By co-doping with two impurities, both sides of the zinc oxide lattice contribute to the film conductivity resulting in high electron concentration and high mobility. The co-doped zinc oxide thin film has an increased Fermi level and a reduced work function that is less than 3 eV. The co-doped zinc oxide is crystal clear and transparent even when grown at relatively low processing temperatures. In another preferred embodiment of the present invention, a novel low-temperature activation indium tin oxide (ITO) thin film comprising tin oxide co-doped with indium (In) and hydrogen is disclosed.

Abstract: The present invention relates to a micro electromechanical (MEM) isolator in which an input signal induces an output signal by means of electrically insulating mechanical motion. The MEM isolator device comprises a dielectric moveable platform suspended above a substrate by flexible beams. A drive and a control capacitor each have one electrode supported by the platform and one electrode supported by the substrate. Coupling between electrical and mechanical energies is achieved by providing an input signal to the drive capacitor to induce platform motion. When the input signal is fed to the drive capacitor, it actuates electrostatic motion of the platform resulting in a change in the value of the control capacitance. The change in the control capacitance is converted via a simple electronics circuit into an output that mirrors the input but is electrically isolated therefrom.

Abstract: The present invention discloses a combination fishing lure comprising a common crankbait and jacket. The removable jacket is a highly elastic covering molded into a seamless, elongated shell that is stretchable over the crankbait. The thickness of the jacket provides a natural flesh-like texture to wood, hard plastic or metal crankbaits while protecting the crankbait from scratches caused by fish strikes or by collision with other objects. The jacket has a cavity with at least a first opening providing access to the cavity. The crankbait is removably positioned in the cavity of the jacket by stretching the jacket in the region surrounding the opening until it is large enough to insert the crankbait. The jacket may include a rearwardly projecting tail portion that changes the appearance of the crankbait by increasing the overall length of the crankbait and that moderates the erratic wobble of the crankbait creating a realistic undulating swimming action.

Abstract: The present invention relates to fault detection in a large population of motors of a common motor type. Initially, a plurality of motors of a common motor type is tested to obtain a first residual based on selected measured operating parameters. A second residual is then developed for each individual motor comprising the plurality of motors. If the difference between the first and second residuals exceeds a selected threshold, the motor generating the second residual is defective and removed from the plurality of motors and the threshold is adjusted to reflect the removal of the defective motor from the plurality of motors. The first residual may be used to monitor the operation of motors not included in the original plurality of motors to detect impending failure.

Abstract: A practice golf club putter is provided where the putter head is ball-shaped having a bore in which a shaft is inserted and firmly affixed to form a single unit. The shaft has a single bend closely proximate to the putter head that provides an offset between the longitudinal axis of the shaft and the axis of the bore. This offset provides numerous advantages for both right and left handed golfers. Specifically, a golfer may position the shaft of the practice putter in an off-set relationship with respect to the hitting zone of the putter head so that the club alignment approximates the relationship of the shaft angle with respect to the hitting zone of a USGA-approved putter.

Abstract: The present invention relates to micro electromechanical systems (MEMS) devices and more specifically to a process for manufacturing MEMS devices having at least one suspended structural element. The present invention seeks to provide an improved method for manufacture of MEMS devices having improved safety and increased yield and throughput compared to conventional EDP immersion process techniques. MEMS devices are made using a modified dissolution process that removes, in a selective etch step, inactive silicon to release an active silicon device from a sacrificial substrate. The present invention uses a selective etchant in conjunction with a commercial spray acid processing tool to provide a dissolution process with improved throughput, improved repeatable and uniform etch rates and reduction in the number of processing steps and chemical containment for improved safety.

Abstract: The present invention relates to a diagnostic system for complex systems such as avionics systems. The diagnostic system acquires a description of the system from a variety of design tools and creates a causal network model as an intermediate step. From the causal network model, the diagnostic system builds and compiles a Q-DAG model of the system, which is then embedded in the central maintenance computer of the aircraft. The present invention integrates two elements, a graphical user interface (GUI), which acts as a data capture tool and graphical display of the avionics system and an inference system, which acts as a diagnostic tool with a presenter. The presenter permits diagnosis of faulty sub-systems and a report may be relayed to remotely located maintenance crews to minimize repair time upon arrival of the aircraft.

Abstract: A networked information sharing model is described. The network described comprises a client-server model or a client only model. There exists a shared information database, a shared category database, a shared interest profile database and a shared client enhancement database, each of which is continually and dynamically updated. The shared category database contains categories of interests, within which are weighted and marked information units. Weights are arrived at by empirical use. Marks are maintained to distinguish where the information came from and to access information according to client source preference. The shared interest profile contains a set of profiles which clients are associated with. Useful client categories within profiles are offered when requested. A shared client enhancement list is maintained to identify and weight useful sources of information.

Abstract: The present invention relates to a fabrication process relating to a fabrication process for manufacture of micro-electromechanical (MEM) devices such as cantilever supported beams. This fabrication process requires only two lithographic masking steps and offers moveable electromechanical devices with high electrical isolation. A preferred embodiment of the process uses electrically insulating glass substrate as the carrier substrate and single crystal silicon as the MEM component material. The process further includes deposition of an optional layer of insulating material such as silicon dioxide on top of a layer of doped silicon grown on a silicon substrate. The silicon dioxide is epoxy bonded to the glass substrate to create a silicon--silicon dioxide-epoxy-glass structure. The silicon is patterned using anisotropic plasma dry etching techniques.

Abstract: The present invention relates to a model based fault detection system and method for monitoring and predicting maintenance requirements of electric motors. Since, the method and system of the present invention is software based and utilizes data obtained from no-intrusive measurements, implementation costs are significantly less than prior art maintenance methods.The system comprises computer means coupled to sensors which provide continuous real-time information of the input voltage and current and motor speed. The system and method utilize a multivariable experimental modeling algorithm to obtain a mathematical description of the motor. The algorithm compares the modeled result with a measured result and quantifies the comparison in terms of a residual which is generated by subtracting the respective signals. A diagnostic observer analyzes the residual and determines if the motor is fault free or operating in a manner other than fault free.

Abstract: The present invention relates to thin film retardation plates, such as cholesteric and A-plate compensators, for improving the viewing angle and contrast of liquid crystal displays. The A-plate is fabricated using a single substrate onto which a layer of polymerizable reactive mesogens (RMs) is solvent cast. Included in the RMs solution is an additive that migrates to the RM/air interface to lower the surface energy and generate an additive-rich surface layer, which in turn lowers the intrinsic tilt angle of the RMs at the air interface to between 25 degrees (25.degree.) and about zero degrees (0.degree.). The solvent is evaporated and the resulting film is polymerized in the liquid crystal phase to permanently orient the liquid crystal. The resulting film may be readily separated from the substrate and shaped into any desired pattern and combined to form novel compensators.
