Abstract: A PDP constructed out of one or more Plasma-shells with a luminescent substance(s) located in close proximity to each Plasma-shell. The luminescent substance comprises a combination of an organic luminescent substance and an inorganic luminescent substance. The combination may be a mixture of organic and inorganic substances. Layers of organic and inorganic substances may be used. Each Plasma-shell is a hollow geometric body filled with an ionizable gas at a suitable pressure. Photons from the gas discharge inside the Plasma-shell excite the luminescent substance. In one embodiment the luminescent substance is located on the external surface of the Plasma-shell. In another embodiment, the luminescent substance is located inside the Plasma-shell. Plasma-shell includes Plasma-sphere, Plasma-disc, and Plasma-dome. The Plasma-shell may be used in combination with a Plasma-tube.
Abstract: A method is provided for measuring the wall thickness of transparent articles using uniform diverging light in the form of a small point source or elongated narrow line of light, measuring the spacial separation of the reflections from the nearest and furthest surface by means of a two-dimensional image sensor and a computational device to calculate the geometrical corrections needed to provide accurate thickness measurements. In situations where significant thickness variations occur, a symmetrical two view embodiment using two uniform diverging light sources and two image sensors at equal but opposite angles of incidence from the same side of the object, provides a means to correct for errors caused by internal prism effects as a result of undulations of either the nearest or furthest surface. This system provides accurate thickness measurements over a wide range of object movement.
Abstract: A radiation detection device comprising a plasma display panel (PDP) with a multiplicity of radiation detection pixels, each radiation detection pixel being defined by a hollow gas filled Plasma-shell having one or more flat sides. Arrays of Plasma-shells are positioned on a suitable base such as a substrate and used to inspect and detect radiation from a selected object. Each Plasma-shell may be of any suitable geometric configuration, including a Plasma-disc and a Plasma-dome. Luminescent material may be positioned near or on each Plasma-shell to provide or enhance light output. A flexible base substrate may be used to wrap a layer or blanket of radiation detection Plasma-shells about the selected object.
Abstract: There is disclosed the priming or conditioning of an AC gas discharge plasma display panel for improved selective write and selective erase which comprises addressing n number of rows in an order or sequence that is changed from frame to frame such that later rows to be addressed are advanced in the sequence with each subsequent frame. Each frame consists of the addressing of all n rows. Specific embodiments include the use of plasma-shells, plasma-tubes, and/or combinations thereof.
Abstract: There is disclosed a process for fabricating a positive column gas discharge plasma display device comprising one or more ionizable gas filled elongated Plasma-tubes. The display may be a dual substrate or a single substrate device. The ionizable gas typically produces photons in the UV, IR, and/or visible range during gas discharge. The photons may excite one or more phosphors located on or in close proximity to one or more Plasma-tubes. The plasma display device may contain at least one Plasma-shell that produces photons in the UV, IR, and/or visible range during gas discharge. Plasma-shell includes Plasma-disc, Plasma-dome and Plasma-sphere.

Abstract: The following invention describes a padded coverslip for a long spinal board. The padding may be composed of a foam core that has a waterproof covering. The shape of the pad may vary to allow it to fit onto any adult size long spinal board. Additional sizes of the pad are also included for pediatric spinal boards. Additional integrated padding may be incorporated at the head of the pad in order to elevate the head of the patient to an anatomically neutral position. Emanating from the sides of the padding is an elastic coverslip that would wrap around a spinal board, securing the pad to the board. Openings within the coverslip would correspond with handhold slots along the sides of the spinal boards.

Abstract: A method is provided for measuring the wall thickness of transparent articles using non-collimated and diverging light in the form of a small point source or elongated narrow line of light, measuring the spacial separation of the reflections from the nearest and furthest surface by means of a two-dimensional image sensor and a computational device to calculate the geometrical corrections needed to provide accurate thickness measurements. In situations where smooth thickness variations occur, a symmetrical two view embodiment using two non-collimated and diverging light sources and two image sensors at equal but opposite angles of incidence from the same side of the object provides a means to correct for errors caused by internal prism effects as a result of undulations of either the nearest or furthest surface.
Abstract: An electrical system for a vehicle such as a truck wherein a power source is split or divided into a plurality of branch power lines to transmit power and data to a variety of systems and subsystems throughout the vehicle, each line having a fuse and a filter so that the data is isolated on the individual circuits while power is delivered to such circuits. In one embodiment, the system includes a J560 connector with a data filter, data control circuitry, and one or more power line transmitters and receivers being incorporated into the J560.

Abstract: The present invention allows the determination of trace levels of ionic substances in a sample solution (ions, metal ions, and other electrically charged molecules) by coupling a separation method, such as liquid chromatography, with ion selective electrodes (ISE) prepared so as to allow detection at activities below 10−6M. The separation method distributes constituent molecules into fractions due to unique chemical and physical properties, such as charge, hydrophobicity, specific binding interactions, or movement in an electrical field. The separated fractions are detected by means of the ISE(s). These ISEs can be used singly or in an array. Accordingly, modifications in the ISEs are used to permit detection of low activities, specifically, below 10−6M, by using low activities of the primary analyte (the molecular species which is specifically detected) in the inner filling solution of the ISE. Arrays constructed in various ways allow flow-through sensing for multiple ions.
