Title: Catheter with fluid medication injectors
Inventor: VIGIL DENNIS M
IPC: A61F2/958
Filed: 1996-09-23
Granted: 2001-09-04
Abstract: A device for injecting medication into a vessel wall includes a plurality of flexible tubes mounted between a multi-lumen catheter and a grommet. A push-pull wire is connected to the grommet and passed through a lumen of the multi-lumen catheter. A plurality of injectors are mounted on each of the flexible tubes. During use, the device is first positioned in a vessel. The push-pull wire is then partially withdrawn forcing the grommet to advance towards the multi-lumen catheter. The advancing grommet forces the flexible tubes to bow outwardly, embedding the injectors into the vessel wall. A fluid medication is then introduced through the multi-lumen catheter, into the flexible tubes and out of the injectors for infusion into the vessel wall.

Granted: 2005-02-15
Abstract: A system and method for processing analog XYZ calligraphic video signals for presentation as a stroke image on a flat panel LCD raster display screen by converting such signals in coordinated sets to digital data in a stroke frame buffer memory. The X and Y signals define column and row addresses in memory for storage of the coordinated Z digital color brightness data, which addresses correspond to pixel locations on the surface of the display screen to which the data is transferred to form the stroke image. By storing fractional bits from the X and Y digital data in the buffer memory along with the coordinated color intensity data a high resolution stroke image can be formed using a conventional sized buffer memory. Further, noise and clock conversion artifacts are minimized by saving the first point of each stroke line or vector and by using the X and Y fractional bits for beam shaping utilizing anti-abasing discs. The discs are a set of prestored circular intensity profiles, each covering several pixels and having their respective centers variously offset by fractions of a pixel spacing from points defining the ideal center of the stroke line to be formed. Appropriate discs are successively copied to memory in overlapped manner for each pixel, based on the location of the profile center with respect to a stroke defining point in the pixel. The data output from the stroke frame buffer is thus shaped by the disc data in presenting the high resolution, anti-aliased stroke image on the raster display screen.

Abstract: A fuel level indicator system that utilizes a resistor card having an arc-shaped resistive path with a first set of spaced apart conductor lines and an arc-shaped resistive ink material overlying the first set of conductor lines. The first conductor lines are formed at an angle with respect to a radial line drawn from the center of the resistive path arc. The resistor card also has an arc-shaped continuously solid conductor base and a second set of spaced apart conductor lines extending from the base at an angle with respect to a radial line drawn from the center of the arc-shaped conductor base. The system includes a wiper assembly having a pair of spaced apart arms. Each arm has a plurality of parallel fingers extending from one end. One of the fingers on a first arm engages a conductor line on the resistive path and a second finger on the first arm engages an adjacent conductor line along the resistive path. A first finger on the second arm engages a conductive line on the conductive path; and a second finger engages an adjacent conductor line on the conductive path. The wiper assembly is constructed and arranged to provide rotational movement along the arc-shaped conductive path and arc-shaped resistive path.  The system also has a float with an extending lever that is connected to the wiper assembly to produce rotational movement of the wiper assembly as the float moves.

Title: Apparatus for defining properties in finite-state machines
Inventor: GLASER ARTHUR BARRY
IPC: G06F17/50
Filed: 1997-06-10
Granted: 2001-01-16
Abstract: A method and apparatus for defining a system design specification by using a finite set of templates that have a format for accepting a set of system expression such that a selected template, when filled with the system expressions, defines an expected behavioral attribute of the system. In one illustrative embodiment, each template has a set of qualifiers and a set of entry blanks, wherein each qualifier is associated with a entry blank. In such an embodiment, the set of entry spaces may comprise a fulfilling condition entry space for accepting a system expression that defines a required or assumed event of the system model, an enabling condition entry space for accepting a system expression that defines a precondition for starting a check of the required or assumed event, and a discharging condition entry space for accepting a system expression that defines a condition after which said fulfilling condition is no longer required or assumed by the system model. Filling the entry spaces of a selected template with the appropriate system expression can form an expression that defines an expected behavior of the system model. Thus, a set of filled templates can define a set of expected behaviors of the system model (i.e. a system design specification). The system design specification can then be used to generate computer-executable code (e.g. automata) for testing the expected behavioral attributes of the system. For example, each filled template of the system design specification can be converted to an automaton by a given subroutine.

Title: Heat-sensitive composition and method of making a lithographic printing form with it
Inventor: RILEY DAVID STEPHEN

Granted: 2003-01-21
Abstract: There is described coated on a lithographic base a complex of a developer-insoluble phenolic resin and a compound which forms a thermally frangible complex with the phenolic resin. This complex is less soluble in the developer solution than the uncomplexed phenolic resin. However when this complex is imagewise heated the complex breaks down so allowing the non-complexed phenolic resin to the dissolved in the developing solution. Thus the solubility differential between the heated areas of the phenolic resin and the unheated areas is increased when the phenolic resin is complexed. Preferably a laser-radiation absorbing material is also present on the lithographic base. A  large number of compounds which form a thermally frangible complex with the phenolic resin have been located. Examples of such compounds are quinolinium compounds, benzothiazolium compounds, pyridinium compounds and imidazoline compounds.

Abstract: Prior to sending to a requesting client device a requested multimedia application which comprises a plurality of kinds of materials and a scenario which defines a role of each material, the server converts an input (or original) format of a certain kind of materials of the requested application into a format with which the requesting client device can deal and converts format-dependent data of the scenario accordingly. This enables every consuming device to consume any of the multimedia applications stored in the server regardless of the material format with which the consuming device can deal with respective to a certain kind of materials. Four schemes different in conversion timing of the materials and the scenario are disclosed. The original format of the materials may be limited to a master data format, eg., the DV format if the certain kind of materials are moving picture materials.
