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.

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.

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.

Abstract: A fluorescent lamp is provided which is resistant to lumen depreciation. The fluorescent lamp includes a tube constructed of an ultraviolet (UV) radiation transmissive material. A gas inside of the tube produces UV radiation in response to a stimulus. Phosphor particles in a phosphor particle containing coating adhered to an outer surface of the tube absorb UV radiation produced by the gas inside of the tube and producing visible light in response.

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.

Messages are displayed on a display to aid a user.

Abstract: A method, system and program for supporting a dynamic bind between a derived class and its parent class. A processor provides for the registration of class objects and dynamic binding of derived class objects to their parent class objects based on the registration mechanism. The SOM object model removes static references to class objects by having all the parent class information available at runtime through the parent class object. Thus, when the derived class implementation needs information about the size of the parent class state data structure, the addresses of the parent class method procedures, or access to the parent class method procedure table the appropriate information is retrieved from the parent class object.

Abstract: An improved architecture for a Prolog interpreter/compiler is described to facilitate interrupt processing. The new architecture employs interrupt control words and a set of interrupt control blocks to enhance Prolog processing. As interrupts are detected, an interrupt control word is loaded with the address of an interrupt control block for managing interrupt processing. Then, each time a new predicate is fired, the interrupt control word is tested and control is passed to the interrupt processing routine if the control word is non-zero.

Abstract: An improved technique for processing Prolog objects is described. The first bit of the Prolog object word is used as a flag to indicate whether the object word is a type pointer or type descriptor. If the one-bit flag indicates that the object word is a type pointer, then the address is available for immediate processing without the unnecessary processing associated with the prior art.

Abstract: A method and apparatus for an object based notification system. The notification system is designed in a flexible manner to support change notification in an object based operating system.

Abstract: A method and apparatus for editing the displayed voice wave form by marking the portion of interest on the screen is disclosed. Marked segment may then be deleted, for example, or copied into another segment in second voice editing window. In either case, pointers are established at the selected marker positions of the displayed voice segment and in the corresponding positions of uncompressed voice segments. The voice data is treated as a stream of fixed-length micro-segments, where there is a predictable correlation between the positions of the compressed and uncompressed data. In the implementation at hand, these micro-segments are 20 ms. in length. Editing is accomplished by modifying micro-segments in both the compressed and uncompressed segments simultaneously. When the user is satisfied with the result, the edited wave form is redrawn on the screen. The user may then SAVE the result, and the entire segment is rewritten to the data base, replacing the previous version.
