Title: Dual serial pressure regulator for ink-jet printing
Inventor: OLSEN DAVID
IPC: B41J2/175
Filed: 2002-03-01
Abstract: An ink containment and delivery system provides high sustained flow rates, allows higher "burst" (short time interval) flow rates, and allows bubble movement through the system conduits to the printhead, all while holding the printhead ink pressure in a range required for optimum printhead operation.  The system includes an ink supply (70) with a first, upstream pressure regulator (60) which maintains a negative ink pressure within the ink supply.  A second, downstream pressure regulator (100) at the printhead (80) maintains negative pressure in the printhead, and allows some compliance about the set point. The ink containment and delivery system allows drool-free separability of the ink supply and the printhead.

Title: Fluid vaporizing device having controlled temperature profile heater/capillary tube
Inventor: COX KENNETH A
IPC: A61M15/00
Filed: 2002-09-10
Abstract: A fluid vaporizing device (10) includes a capillary tube (20) made from an electrically conductive material, an upstream electrode (32) and a downstream electrode (34) connected to the tube (20). The downstream electrode (34) is provided with an electrical resistivity sufficient to cause heating of the downstream electrode during operation to approximately the same temperature as the tube at the point of connection. A source of material (12) to be volatilized is provided to the tube at the feed section (22), into the heated section (24) and is vaporized, and then exits from the tube through the tip (29). The temperature profile of the tube along the heated section (24) is controlled by varying parameters to substantially eliminate any effect of the downstream electrode (34) as a heat sink. These parameters may include the electrical resistivity of the downstream electrode (34), its cross-sectional area and its length.

Title: Device and method for adaptive ultrasound sensing
Inventor: AGAM URI
IPC: E05F15/70
Filed: 2003-12-23
Abstract: The adaptive system and method for ultrasound sensing comprises re-evaluating over time the detection threshold for predetermined sensing positions along the scanning direction to cope for the static target and environment changes at the sensing positions. The method includes comparing the measured echo value at each sensing position to a reference echo value corresponding to the same sensing position, and to iteratively determine a new reference value whenever the echo value is greater than the reference echo value and that the difference between the measured echo value and the reference echo value is lower than a detection assurance factor. The use of the adaptive ultrasound sensing system and method allows locating the sensor at different location without requiring a new calibration thereof, since the sensor learns the clutter dynamically and the detection thresholds are being built accordingly without being dependent on the environment in which the sensor is located.

Abstract: A runner-less molding device for thermosetting resins and rubbers, characterized by a movable runner bush (15), through which an uncured or unvulcanized fluid material kept at a low temperature supplied from a pouring nozzle (31) can flow, is slidably arranged in a temperature controlling bush (13) communicating with a gate (4) of a cavity (1); an insulation space (A) is formed by moving the movable runner bush (15) apart from the gate (4) during heating; a valve pin (18) is movably inserted into said movable runner bush (15); and the valve pin (18) is arranged so as to open and close the gate (4) in accordance with a pouring operation of the fluid material. A runner part of the movable runner bush containing molding material is constituted so as to move forward/backward relative to the cavity for preventing heat from conducting from the cavity, which is kept at a molding temperature, to the runner positioned apart from the gate for a long time, so that material loss generated in a sprue runner is reduced to almost null in order to reduce fabricating costs after molding and amount of wastes generated during after treatments. Thus, the improved molding device for the thermosetting resin and the rubber is obtained, and burdens on the global environment are alleviated.

Abstract: A solid material (M1X) (6) comprising a solid solution of a non-metal species (X) in a metal or semi-metal (M1) or a compound between the non-metal species and the metal or semi-metal is immersed in a molten salt (M2Y) (4). A cathodic potential is applied to the material to remove a portion of the non-metal species by electro-deoxidation. As this reaction proceeds it becomes less efficient and so to remove the non-metal species at lower concentrations a source of a reactive metal (M3) (8) is immersed in the molten salt and is electronically connected to the material, either by electronic conduction through the salt or through an external circuit. Reactions occur at the material, where the non-metal species dissolves in the salt, and at the reactive metal, which reacts with the non-metal species dissolved in the salt to form a reaction product more stable than a compound between the non-metal species and the metal or semi-metal (M1). The non-metal species is thus removed from the solid material.

Abstract: L'invention concerne un procédé de détection du phénomène yeux rouges (1) dans une image numérique. Ce procédé consiste à identifier des régions (2) d'éclairage principal de l'image ayant des pixels d'une tonalité sensiblement rouge et présentant des valeurs de saturation et de clarté plus élevées que les pixels dans les régions qui l'entourent. De plus, les zones des pupilles (3) comprenant deux pics de saturation de chaque côté d'un minimum de saturation peuvent être identifiées. On détermine alors si chaque éclairage principal ou chaque zone des pupilles correspond à une partie du phénomène yeux rouges selon d'autres critères de sélection, qui peuvent consister à déterminer s'il y a une zone sensiblement circulaire isolée (43) de pixels pouvant être corrigés autour d'un pixel de référence. La correction du phénomène yeux rouges consiste à réduire la clarté et/ou la saturation de certains ou de tous les pixels dans le phénomène yeux rouges.

Title: Self calibrating apparatus and method for ultrasonic determination of fluid properties
Inventor: GREENWOOD MARGARET STAUTBERG
IPC: G01N29/032
Filed: 2003-01-14
Abstract: A system and technique for determining fluid properties includes an ultrasonic transducer 30 on a first surface 42 of a solid member 40. An opposed second surface 44 of the member 40 is in contact with a fluid 25 to be monitored. A  longitudinal ultrasonic pulse is delivered through the solid member, and a multiplicity of pulse echoes caused by reflections of the ultrasonic pulse between the solid-fluid interface and the transducer-solid interface are detected and processed by a processing apparatus 22. The apparatus 22 determines the decay rate of the detected echo amplitude as a function of echo number and compares this value to a calibrated decay rate to determine an acoustic property of the fluid. The speed of ultrasound in the fluid is also determined and the fluid density is determined as a function of the speed of ultrasound and the determined acoustic property. When coupled with a shear wave transducer, additional properties corresponding to the fluid viscosity, shear modulus, or shear speed are also determined. Both a fixed in place sensing system and a clamp-on sensing system are disclosed.
