Patent number: 10177498Abstract: An electrical connector assembly which has a first connector and a second connector. The first connector and second connector have connector housings with first latching areas extending from the top surfaces of the connector housings and second latching areas extending from the bottom surfaces of the connector housing. Sealing members are positioned proximate wire-receiving faces of the connector housings. Rear seal cover members are positioned in the connector housings. The rear seal cover members are configured to cooperate with the sealing members to prevent the rear seal cover members from being latched to the connector housing when the terminals are not fully inserted into the terminal receiving cavities of the connector housings.Type: GrantFiled: February 19, 2018Date of Patent: January 8, 2019Assignee: TE CONNECTIVITY CORPORATIONInventors: Chong Hun Yi, Matthew David Morrison, Christopher Rowland

Publication number: 20160135669Abstract: A fluid delivery system for use with an endoscope. Certain embodiments of the invention include a single, large fluid source and pump installed upon an operator console, in combination with a small fluid reservoir and pump installed within a proximal connector of the imaging endoscope, multiple fluid sources that feed a common fluid channel that are pressurized by a common pump, multiple fluid sources that feed dedicated fluid channels that are pressurized by dedicated pumps, and a small fluid reservoir and pump installed within a handheld manual controller of the imaging endoscope. The fluid delivery endoscopic systems of the present invention provide the user with the flexibility of changing fluids either in advance of a procedure or on-the-fly as needed, instead of relying on fixed fluid sources only.Type: ApplicationFiled: January 21, 2016Publication date: May 19, 2016Applicant: Boston Scientific Scimed, Inc.Inventors: Dennis R. BOULAIS, Michael S. BANIK, Vincent TURTURRO, Christopher ROWLAND, David W. HOFFMAN, John P. O'CONNOR, Eric LITSCHER

Patent number: 8746666Abstract: A media carrier, adapted to hold a plurality of pieces of magnetic media, is disclosed. This media carrier can be placed on the workpiece support, or platen, allowing the magnetic media to be processed. In some embodiments, the media carrier is designed such that only one side of the magnetic media is exposed, requiring a robot or other equipment to invert each piece of media in the carrier to process the second side. In other embodiments, the media carrier is designed such that both sides of the magnetic media are exposed. In this scenario, the media carrier is inverted on the platen to allow processing of the second side.Type: GrantFiled: May 5, 2011Date of Patent: June 10, 2014Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Richard Hertel, Julian Blake, Edward Macintosh, Alexander Kontos, Frank Sinclair, Christopher Rowland, Mayur Jagtap, Sankar Ganesh Kolappan

Patent number: 8357148Abstract: A multi-functional endoscopic system, for use in electrosurgical applications, that includes an imaging endoscope that may be used in combination with various electrosurgical devices, all of which are sufficiently inexpensive to manufacture, such that the endoscope and electrosurgical devices are considered single use, disposable items. The multi-functional endoscopic system of the present invention is suitable for use with a variety of common electrosurgical devices that require electrical/electronic support in order to function. The electrical/electronic support for these electrosurgical devices (e.g., an electrosurgical generator and associated controls) is integrated with the operator console of the imaging endoscope of the multi-functional endoscopic system of the present invention, rather than provided as a separate device.Type: GrantFiled: September 29, 2005Date of Patent: January 22, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Dennis R. Boulais, Michael S. Banik, Vincent Turturro, Christopher Rowland, David Hoffman, John P. O'Connor

Patent number: 4057049Abstract: Apparatus and method for the examination of specimens, particularly human tissue in vivo, by pulse-echo ultrasonic methods. To compensate for the variable and unpredictable attenuation of examining signals when reflected from different targets within the specimen, the echoes are processed -- for instance by frequency analysis -- to produce at least two sets of echo-amplitude information. These sets of information are in turn processed to produce a quantity indicative of the attenuation actually undergone by signals in examining each particular target. This quantity may then be applied to the "A" - scan, "B" - scan or other displays of the echoes of the examining signals to compensate them for the effects of varying attenuation. The apparatus may also include similar uncompensated displays and displays directly representing the attenuation co-efficients of the regions of tissue under scan; comparison of these with the compensated displays may reveal further useful information.Type: GrantFiled: October 7, 1975Date of Patent: November 8, 1977Assignee: National Research Development CorporationInventor: Christopher Rowland Hill
