Patent number: 8984929Abstract: A pressure indicating device for detecting and isolating leakage of toxic and/or pyrophoric gasses from within various packages is disclosed. The device can affix to a user port of a cylinder package. The device has a flexible disc-like structure which is fine tuned to outwardly flex in response to a build-up of pressure of the gas exerted against the disc-like structure. The flexed disc contacts a movable pin and pushes the push outwards from within the device. The outward movement of the pin pierces a paper seal extending over the device, thereby indicating a leak from within the valving of the package. The device withstands the pressure exerted against it, thereby also isolating the leak of the pressurized gas.Type: GrantFiled: December 19, 2012Date of Patent: March 24, 2015Assignee: Praxair Technology, Inc.Inventors: Lisa A. Fanti, Lloyd A. Brown, Serge M. Campeau, Ronald F. Spohn, Murat Gunay

Publication number: 20140325460Abstract: A system and method for an automated way of running spice on a small portion of a design is presented. The system includes a sub-circuit netlist generation processor and an analog simulation processor. The sub-circuit netlist generation processor generates a sub-circuit netlist based, at least in part, on a HDL netlist, a parasitic capacitance database and trace rules. The sub-circuit netlist contains significantly fewer paths than the HDL netlist of an entire design so that its simulation time is much quicker. The analog simulation processor generates analog simulation results of the sub-circuit netlist based, at least in part, on dynamic inputs.Type: ApplicationFiled: April 11, 2014Publication date: October 30, 2014Applicant: BAE Systems Information And Electronic Systems Intergration Inc.Inventors: Richard Ferguson, Lloyd Brown

Publication number: 20130341568Abstract: A novel method and system for extending ion source life and improving ion source performance during carbon implantation are provided. Particularly, the carbon ion implant process involves utilizing a dopant gas mixture comprising carbon monoxide and one or more fluorine-containing gas with carbon represented by the formula CxFy wherein x?1 and y?1. At least one fluorine containing gases with carbon is contained in the mixture at about 3-12 volume percent (vol %) based on the volume of the dopant gas mixture. Fluoride ions, radicals or combinations thereof are released from the ionized dopant gas mixture and reacts with deposits derived substantially from carbon along at least one of the surfaces of the repeller electrodes, extraction electrodes and the chamber to reduce the overall amount of deposits. In this manner, a single dopant gas mixture provides carbon ions and removes problematic deposits typically encountered during carbon implantation.Type: ApplicationFiled: June 20, 2012Publication date: December 26, 2013Inventors: Ashwini K.

Publication number: 20120235058Abstract: This invention relates in part to a method for preventing or reducing the formation and/or accumulation of deposits in an ion source component of an ion implanter used in semiconductor and microelectronic manufacturing. The ion source component includes an ionization chamber and one or more components contained within the ionization chamber. The method involves introducing into the ionization chamber a dopant gas, wherein the dopant gas has a composition sufficient to prevent or reduce the formation of fluorine ions/radicals during ionization. The dopant gas is then ionized under conditions sufficient to prevent or reduce the formation and/or accumulation of deposits on the interior of the ionization chamber and/or on the one or more components contained within the ionization chamber. The deposits adversely impact the normal operation of the ion implanter causing frequent down time and reducing tool utilization.Type: ApplicationFiled: September 12, 2011Publication date: September 20, 2012Inventors: Ashwini SINHA, Lloyd A.

Publication number: 20040019646Abstract: A system and method for personalizing content delivery to a customer over time and across channels. In one embodiment, based on a customer's demographics or behavioral characteristics, the method transmits an electronic mail message to a customer, wherein the message comprises a link to an Internet site. Next, the method waits for a specified amount of time and then transmits a bulk mail message to the customer, if the customer did not click on the link. The method then prompts a telemarketer to place a telephone call to the customer, if the customer did not respond to the bulk mail message within another specified amount of time.Type: ApplicationFiled: March 18, 2003Publication date: January 29, 2004Inventors: Monte Zweben, Robert Lloyd Brown, Christopher B.

Publication number: 20040015069Abstract: A system for locating inflamed plaque in a vessel is provided herein. The system includes a receiver, a positioner and a sensor. The receiver receives information about a vessel wall of the vessel. The positioner is used to position the receiver in the vessel to receive information from the vessel wall. The sensor is connected to the receiver. In use, the positioner selectively moves the receiver in the vessel to collect information about the vessel wall. The information is then transferred to the sensor to determine the temperature at the vessel wall. Temperatures at various locations can be taken, with elevated temperatures being indicative of inflamed plaque.Type: ApplicationFiled: December 26, 2001Publication date: January 22, 2004Inventor: David Lloyd Brown

Patent number: 5871449Abstract: A system for locating inflamed plaque in an artery of a patient includes a catheter with an expander mounted at a catheter distal end. An infrared carrier, e.g., an optical fiber is mounted on the catheter with a carrier distal end attached to the expander. A sensor is connected to a carrier proximal end to measure infrared radiation transmitted through the carrier from the carrier distal end. In use, the expander is operable to selectively move the carrier distal end into contact with the arterial wall. Infrared radiation can then be measured to determine the temperature at the arterial wall. Temperatures at various locations can be taken, with elevated temperatures being indicative of inflamed plaque.Type: GrantFiled: December 27, 1996Date of Patent: February 16, 1999Inventor: David Lloyd Brown
