Publication number: 20050258356Abstract: The present invention is directed to a bipolar ion detector capable of detecting both positive and negative ions in a single configuration. The invention uses either a single microchannel plates or a stack of microchannel plates to convert the ion signal into an amplified electron signal. Circuitry allows the anode to be biased (floated) to a positive high voltage and efficiently couple the signal from the anode out to recording electronics at ground.Type: ApplicationFiled: May 19, 2005Publication date: November 24, 2005Inventors: Scott Ecelberger, Douglas Lewis, Keith Soldavin

Publication number: 20050242578Abstract: Hose coupling devices that securely connect an end of a hose to a fitting member using a retention mechanism operated by multi-threaded engagement of the fitting member with a collar member. The multi-threaded engagement also may operate a hose advancement mechanism. The advancement mechanism axially advances a hose during multi-threaded engagement so that the hose may be more effectively gripped by the retention mechanism.Type: ApplicationFiled: June 21, 2005Publication date: November 3, 2005Inventors: Daniel Evans, N. Leuck, Douglas Lewis, Daniel Lyman

Publication number: 20040236350Abstract: Methods for treating total and partial occlusions employ a perfusion conduit which is penetrated through the occlusive material. Oxygenated blood or other medium is then perfused through the conduit in a controlled manner, preferably at a controlled pressure below the arterial pressure, to maintain oxygenation and relieve ischemia in tissue distal to the occlusion. In another aspect, interventional devices, such as stents or balloon catheters, are passed through the perfusion catheter to remove obstructions. Optionally, the occlusion may be treated while perfusion is maintained, typically by introducing a thrombolytic or other agent into the occlusive material using the perfusion conduit or by employing mechanical means to remove the obstruction. Such methods are particularly suitable for treating acute stroke to prevent damage to the cerebral tissue.Type: ApplicationFiled: June 26, 2002Publication date: November 25, 2004Applicant: SALIENT INTERVENTIONAL SYSTEMS, INC.Inventors: Brian Douglas Lewis, Lee R.

Patent number: 6801216Abstract: A makeover system and method for using the system is provided for providing a user with an image of how a person would look with different hair, glasses, makeup, etc. Using a before picture of the person, the system displays an item on the before picture and resizes the item to fit the size of the person according to user input. Therefore, the makeover system can superimpose an item over an image of a person regardless of the size of the image of the person on a computer screen. The system then provides an after picture representing a composite image of the superimposed selected overlay item over the image of the person.Type: GrantFiled: February 23, 2001Date of Patent: October 5, 2004Inventors: Michael Voticky, Richard Hogan, Douglas Lewis, Christopher J.

Publication number: 20040103516Abstract: An intravascular device and method of constructing an intravascular device. The device has a proximal portion which is stiffer than a distal portion. The device of the present invention may also be advanced through small vessels without the aid of a guidewire although a guidewire may be used when necessary. The device may be manufactured in a number of different ways and a preferred method is to use an expanded PTFE liner at the distal portion and an etched PTFE liner along the proximal portion. The device also has a number of different jacket sections, preferably at least four, with increasing durometer towards the proximal end and a braided section with varying pic along the length.Type: ApplicationFiled: July 9, 2003Publication date: June 3, 2004Inventors: Lee R.

Patent number: 6511327Abstract: A network interface system or device is disclosed that represents an optimal balance in the cost of the materials for the components and the cost of the assembly time required of a field technician. One or more lines from the network provider, e.g., a telephone company, are provided as well as one or more corresponding lines from a customer. For a given network line and corresponding customer line, each line is preferably terminated with a female spade connector. A small printed circuit board (PCB) is provided that has ends shaped to act as male spade connectors. An electrical connection is provided between the ends of the PCB. Optionally, but preferably, a gas tube is provided to suppress surges on the network line before they damage equipment connected to the customer line. A PCB configured in this manner can connect one set or multiple sets of lines.Type: GrantFiled: November 5, 1999Date of Patent: January 28, 2003Assignee: Avaya Technology Corp.Inventors: David Stevens Kerr, Jason A.

Patent number: 6322375Abstract: A network interface device includes a base, a cover and a circuit board secured in the base. The circuit board includes terminations for input and output communication lines. Each pair of input and output communication lines corresponds to a single standard telephone line, a high speed data line or other type of line. The communication line terminations may be implemented as insulation displacement connectors, and the cover may include projections on its inner surface such that closing the cover also closes the insulation displacement connectors on the circuit board. For each communication line, the circuit board may include a subscriber bridge which establishes a breakable connection between the input and output line terminations via traces in the circuit board. In fixed wireless, fiber-to-the-home (FITI) and other similar applications, the circuit board may also include terminations for input and output power lines, and the base and cover may be extended to accommodate an uninterruptible power supply.Type: GrantFiled: September 29, 1997Date of Patent: November 27, 2001Assignee: Avaya Technology Corp.Inventors: Thelma E.
