Publication number: 20090148594Abstract: An interconnection element can be formed by plating a metal layer within holes in an essentially non-metallic layer of a mandrel, wherein posts can be plated onto a metal layer exposed within the holes, e.g., a metal layer covering the holes in the non-metallic layer. The tips of the posts can be formed adjacent to ends or bottoms of the blind holes. Terminals can be formed in conductive communication with the conductive posts. The terminals can be connected through a dielectric layer to the conductive posts. At least a portion of the mandrel can then be removed from at least ends of the holes. In this way, the tips of the conductive posts can become raised above a major surface of the interconnection element such that at least the tips of the posts project beyond the major surface.Type: ApplicationFiled: August 15, 2008Publication date: June 11, 2009Applicant: Tessera, Inc.Inventors: Sean Moran, Jinsu Kwon, Kimitaka Endo

INFORMATION HANDLING SYSTEMS HAVING COATINGS WITH POROUS PARTICLES AND PROCESSES OF FORMING THE SAME
Publication number: 20090147455Abstract: Particles having a relatively high porosity can be used in an information handling system or other information handling system. In one aspect, a portable information handling system can include an electrical circuit that can generate thermal energy during normal operation of the electrical circuit. The portable information handling system can also include a housing that includes a first material and particles having a porosity of at least 80%. In another aspect, an information handling system can include a housing that includes a material and a coating, wherein the coating includes a polymeric material and particles having a porosity of at least 80%. In another aspect, a process of forming an information handling system can include coating a surface of a housing, wherein the coating includes particles having a porosity of at least 80%, and placing an electrical circuit within the housing after coating the surface.Type: ApplicationFiled: December 11, 2007Publication date: June 11, 2009Applicant: DELL PRODUCTS, LPInventors: Mark L.

Publication number: 20080171189Abstract: The invention relates to a system for detecting the defects of a wall used for enclosing a space where—generally liquid—materials are stored, with a coating on its internal side, especially a container wall, or/and the defects in the coating. In numerous fields of life all types of different materials, such as chemicals, solvents, petroleum oil and petroleum fractions, etc. need to be stored in a way excluding the possibility of these materials getting into the environment or other materials from the environment intermixing with the stored materials. In most cases such materials are stored in containers made of different materials, mostly metal, the walls of which holes may appear either as a result of corrosion or other damage, and through the appearing holes materials can flow either from outside into the container or from inside the container into the environment, and so the stored material may become unsuitable for use or serious environmental pollution may occur.Type: ApplicationFiled: November 29, 2005Publication date: July 17, 2008Inventors: Laszlo Varga, Laszlo Kalafszky, Imre Toth

Publication number: 20080121103Abstract: The present invention relates to a three dimensional preconcentrator and inlet heater. The preconcentrator consists of a substrate with passageways, a conductive material coated to the top and the bottom of the substrate and an adsorbent coating covering the entire substrate. This substrate is suspended in a holding frame by a connecting bridge. The preconcentrator may also include a resistor and a proportional-integral-differential controller. The device may be used inline with a detector and can be retrofitted to existing devices. An array of preconcentrators may also be formed. The invention also relates to methods of use of the preconcentrator and methods of manufacture. A method of use includes contacting an analyte and a preconcentrator, allowing the analyte to adsorb to the preconcentrator and then desorbing the analyte. A method of manufacture involves applying the adsorbent coating by misted chemical deposition.Type: ApplicationFiled: December 10, 2007Publication date: May 29, 2008Inventors: Paul Boyle, David Ruiz-Alonzo, Andrew Koehl, Martyn Rush, Russell Parris, Ashley Wilks

Patent number: 6916502Abstract: Systems and methods for applying a coating to an interior surface of a conduit. In one embodiment, a spray gun configured to apply a coating is attached to an extension arm which may be inserted into the bore of a pipe. The spray gun may be a thermal spray gun adapted to apply a powder coating. An evacuation system may be used to provide a volume area of reduced air pressure for drawing overspray out of the pipe interior during coating. The extension arm as well as the spray gun may be cooled to maintain a consistent temperature in the system, allowing for more consistent coating.Type: GrantFiled: February 11, 2002Date of Patent: July 12, 2005Assignee: Battelle Energy Alliance, LLCInventors: Karen A.
