Publication number: 20100203771Abstract: An electrical interconnect system includes a first circuit board that includes at least one via, and a conductor configured to transmit an electrical current therethrough. The conductor includes a first signal contact extending from a conductor first end, and a dielectric cylinder configured to receive the conductor therethrough. The dielectric cylinder includes a first bellows element extending from a first end of the dielectric cylinder that is positioned adjacent to the first signal contact. The first bellows element and the dielectric cylinder are configured to form a substantially continuous outer conductor, wherein the conductor and the first bellows are configured to electrically interface to the via and maintain connection thereto using a biasing force.Type: ApplicationFiled: February 6, 2009Publication date: August 12, 2010Inventors: Patrick Kevin Bailleul, Steven Edward Bradshaw, David Matthew Hudson, Luke Andrew Hardman

Patent number: 7585044Abstract: A method of adjusting an ink jet imaging device comprises measuring a drop parameter for drops generated by each drop generator in a plurality of drop generators. Each drop generator is configured to generate a drop in response to a drop generating signal having a fill portion, an eject portion, and a resonance tuning portion. A first portion of the drops are generated by each drop generator at a first fill density, and a second portion of the drops are generated by each drop generator at a second fill density. A drop parameter difference is measured for each drop generator of the plurality of drop generators of drops generated at the first and second fill densities. The resonance tuning portion of the drop generating signal for at least one drop generator is adjusted so that the drop parameter difference for the drop generator corresponds to the drop parameter difference normalization value.Type: GrantFiled: April 30, 2007Date of Patent: September 8, 2009Assignee: Xerox CorporationInventors: Brian Edward Williams, Terrance L. Stephens, Matthew Hudson Dixon

Publication number: 20090096823Abstract: A method of compensating for changes in drop mass of drop emitted by at least one ink jet of an ink jet imaging device is provided. The method comprises identifying a drop placement position on an image receiving member of an ink jet imaging device for at least one ink jet of a print head. The identified drop placement position for the at least one ink jet is compared to a default drop placement position for the at least one ink jet to determine a difference in drop placement position. A drive signal for the at least one ink jet is then adjusted in accordance with the difference in drop placement position.Type: ApplicationFiled: October 15, 2007Publication date: April 16, 2009Applicant: Xerox CorporationInventors: Russell J. Watt, Matthew Hudson Dixon, Lisa Marie Schmidt, Jeff Lee Nelson

Publication number: 20080086198Abstract: The present invention relates generally to medical devices containing nanoporous surfaces and methods for making same. More specifically, the invention relates to implantable vascular stents or other biomedical devices having at least one nanoporous layer that promotes improved cellular adhesion properties that promote healing and long term biocompatibility. In the case of stents, the nanoporous layer promotes re-endothelialization at sites of stent implantation vasculature, improves overall healing, and reduces inflammation and intimal disease progression. The nanoporous layer may be optionally loaded with one or more therapeutic agent to further improve the function of the implanted stent and further augment clinical efficacy.Type: ApplicationFiled: May 24, 2007Publication date: April 10, 2008Inventors: Gary Owens, Whye-Kei Lye, Michael Reed, Joshua Spradlin, Brian Wamhoff, Matthew Hudson, Kareen Looi

Publication number: 20060276879Abstract: The present invention relates generally to medical devices with therapy eluting components and methods for making same. More specifically, the invention relates to implantable medical devices having at least one porous layer, and methods for making such devices, and loading such devices with therapeutic agents. A mixture or alloy is placed on the surface of a medical device, then one component of the mixture or alloy is generally removed without generally removing the other components of the mixture or alloy.Type: ApplicationFiled: May 11, 2006Publication date: December 7, 2006Inventors: Whye-Kei Lye, Michael Reed, Gary Owens, Brian Wamhoff, Joshua Spradlin, Matthew Hudson

More specifically, the invention relates to implantable medical devices having at least one porous layer, and methods for making such devices, and loading such devices with therapeutic agents. A mixture or alloy is placed on the surface of a medical device, then one component of the mixture or alloy is generally removed without generally removing the other components of the mixture or alloy. In some embodiments, a porous layer is adapted for bonding non-metallic coating, including drug eluting polymeric coatings. A porous layer may have a random pore structure or an oriented or directional grain porous structure. One embodiment of the invention relates to medical devices, including vascular stents, having at least one porous layer adapted to resist stenosis or cellular proliferation without requiring elution of therapeutic agents.Type: ApplicationFiled: May 9, 2006Publication date: December 7, 2006Inventors: Gary Owens, Whye-Kei Lye, Michael Reed, Joshua Spradlin, Brian Wamhoff, Matthew Hudson, Kareen Looi
