  • Patent number: 5808407
    Abstract: An improved fluorescent lamp and a method of preparing the same are described. The fluorescent lamp includes a tube having a first surface which serves as a substrate. A continuous layer of aluminosilicate sol-gel material having phosphor particles embedded therein is formed on the first surface of the tube. The continuous layer of sol-gel material having phosphor particles embedded therein is formed by first preparing an aluminosilicate sol-gel solution. The phosphor particles are next mixed in the aluminosilicate sol-gel solution to obtain a phosphor particle carrying aluminosilicate sol-gel solution. Then, the first surface is coated with the phosphor particle carrying aluminosilicate sol-gel solution. The phosphor particle carrying aluminosilicate sol-gel solution is dried on the first surface to form a phosphor particle containing sol-gel layer.

  • Patent number: 5801374
    Abstract: Conventional packaging of optical sensors is of little assistance in determining the location and attitude of the focal place of the sensor 10, since package tolerances lack the requisite precision. Each sensor 10 must be separately focused to its optical assembly 40. Such focusing is expensive, as is the package itself. This invention instead mounts the sensor 10 directly onto one face 28 of a transparent plate 18. Radiation is focused through the plate 18 and onto the sensor 10. Precision alignment targets 12, 22 are formed separately on the sensor 10 (providing a known location of the active image area 14 with respect to the target 12) and on the plate 18 (providing a known location of the edges 24 of the plate 18 with respect to the target 22). The targets 12, 22 are aligned, and contact pads 16, 30 on the sensor 10 and on the plate 18 are joined by electronically conductive bumps 36 of known thickness. The plate 18 itself is of known thickness.

  • Patent number: 5798745
    Abstract: A display element in a liquid-crystal display having a tailored pushdown voltage is described wherein the pushdown voltage of the display element may be tailored to a predetermined compensation level by varying the size of the thin-film transistor switch of the display element, by varying the size of the storage capacitor of the display element, or by varying both the size of the thin-film transistor switch and the size of the storage capacitor. The pushdown voltage of the display element may be further tailored in conjunction with the cell gap of the display panel. Precise manipulation of the output of the liquid-crystal display may be achieved through manipulation of the size of the thin-film transistor and the storage capacitor wherein various parameters may be controlled including luminance, color balance and aperture ratio for individual colors.

  • Patent number: 5798614
    Abstract: A method and apparatus for driving a fluorescent lamp is described wherein the fluorescent lamp is operated in the phanotronic, or hot-cathode, mode. The filament preheat current is decoupled from the arc current through synchronization of the filament voltage and arc voltage waveforms to provide sense windows during which the filament condition may be precisely and accurately determined. Sensing circuits provide correctional feedback to the filament voltage signal to provide optimal filament heating.

  • Patent number: 5758160
    Abstract: A human oriented object programming system provides an interactive and dynamic process for the incremental building of computer programs which facilitates the development of complex computer programs such as operating systems and large applications with graphic user interfaces (GUIs). The program is modeled as a collection of units called components. A component represents a single compilable language element such as a class or a function. The three major functionality are the database, the compiler and the build mechanism. The database stores the components and properties. The compiler, along with compiling the source code of a property, is responsible for calculating the dependencies associated with a component. The build mechanism uses properties of components along with the compiler generated dependencies to correctly and efficiently sequence the compilation of components during a build process.

  • Patent number: 5742207
    Abstract: A system for processing signals by utilizing a tracking loop that contains two or more detectors that operate simultaneously in order to detect a frequency shift in the locally generated reference signal. A correction can then be transmitted to the tracking loop filter to minimize the effect of the detected frequency shift. In this manner lock can be maintained without the expenditures associated with the use of temperature controlled or compensated oscillators.

  • Patent number: 5726674
    Abstract: A passive matrix liquid crystal display and a method of driving the same are provided. A desired RMS voltage to be achieved during a first frame is determined for each pixel element of the display. A modulation coefficient is determined for each pixel element as a function of the desired RMS voltage for the pixel element during the first frame. For each cycle of the frame, a phase delay is determined for each column drive waveform as a function of the sum, over all rows, of the product of each modulation coefficient of a pixel element in the column and the phase delay of the corresponding row drive waveform during the cycle.

  • Patent number: 5721900
    Abstract: A method, system and program for providing a graphical interface for a database are accomplished by the operation of a process in the memory of a processor. The definition of individual predicates, the definition of the relationship of predicates, the editing of predicates, and the editing of the relationship of predicates is simplified and rendered dynamic and interactive for the user thereby facilitating the completion of the task being performed. The user need not remember the related column information for a specified predicate because the system will provide that information simultaneously with the predicate definition in a form that supports the direct manipulation of the related information. The predicates and their relationship are displayed simultaneously with the definition activities for both the initial definition and any subsequent editing activities. The user may select this information and drag it to the desired location to proceed on the desired activity.

  • Patent number: 5634006
    Abstract: A data processing system for regulating access to a communication network is disclosed herein. The data processing system employs a component that can be implemented in hardware logic or software. The component regulates access to the priority queue or transmit channel that is attached to the shared medium local area network section. All access to the priority queue or transmit channel must pass through this component, thus subjecting all communication transactions to rejection or tracking by the component. The component allocates a frame size based on the information to be transmitted and the priority to assure the transmission will be completed in line with the quality of service required. The component monitors the rate and size of messages to assure that an application's actual throughput does not exceed its negotiated throughput. The component, moreover, is capable of operating in correction mode where throughput and frame size violations are prevented and reported.

  • Patent number: 5615326
    Abstract: A view system provides an extensible mechanism for associating a logical set of windows and manipulating them as a unit. For example, operations can be applied across address spaces to all the members of the group. A group is constructed by inserting a reference to each view in the group in a layer object. The layer object, in turn, can be inserted into a data hierarchy structure in a hierarchy object. The data hierarchy structure defines front to back display levels on a display and defines which windows overlap. Since all the members of the group are in the same layer object, they move to different levels as a group. Polymorphism and extensibility are provided via the object-oriented architecture of the operating system.

  • Patent number: 5563720
    Abstract: A method, system and process for improving image enhancement tools through the application of expert systems. The improvements are accomplished by the operation of a process in the memory of a processor that enhances an image based on a set of criteria entered by a user. The image is enhanced in at least two ways and the two enhanced images are presented to the user. The user selects the image that appears best and the selected image is thereafter used for subsequent image enhancements according to the user criteria until a final image is created.
