Patent number: 9072868Abstract: A system for delivering an antimicrobial agent into the lumen of a trans-dermal catheter. In an embodiment, the system comprises an elongate member configured for insertion into a lumen of a catheter; an expandable portion of the elongate member, said expandable portion configured to increase in diameter upon exposure to an aqueous fluid; and an antimicrobial composition positioned to be delivered into the catheter. In another embodiment, the system comprises an elongate member configured for insertion into a lumen of a trans-dermal catheter, said elongate member comprising a hydrogel; and an antimicrobial composition positioned to be delivered into the catheter; wherein the elongate member defines a volume of liquid that is at least substantially contained within the lumen of the trans-dermal catheter.Type: GrantFiled: October 26, 2009Date of Patent: July 7, 2015Assignee: Pursuit Vascular, Inc.Inventors: Robert J.

Patent number: 6530279Abstract: A first circuit board includes a first plurality of holes to receive an electronic module and to provide an electrical circuit environment to test the electronic module. A second circuit board includes a second plurality of holes cooperatively arranged with the first plurality of holes. The second circuit board is slidably coupled to the first circuit board and slides between an insertion position in which the first and second pluralities of holes are aligned to receive the electronic module and a holding position in which the first and second pluralities of holes are offset to hold the electronic module. A biasing member urges the second circuit board toward the holding position.Type: GrantFiled: March 7, 2002Date of Patent: March 11, 2003Assignee: Screening Systems, Inc.Inventor: Robert H.

Patent number: 5637812Abstract: A testing apparatus which has a test chamber located within a chamber frame. The apparatus includes a computer controlled ergonomic system which can vary the temperature of the test chamber. Within the test chamber is an adjustable ceiling that can be moved to vary the volume of the chamber. Extending around the outer edge of the ceiling is an inflatable seal which seals the chamber when the ceiling is moved to a new position. The ceiling and walls have a plurality of adjustable vents that direct fluid flow into the chamber. The doors of the apparatus are each constructed from an inner wall that is coupled to an outer wall by a plurality of floating joints. The floating joints allow the inner wall to contract or expand relative to the outer wall without creating a corresponding stress on the outer wall or the joints.Type: GrantFiled: November 14, 1994Date of Patent: June 10, 1997Assignee: Screening Systems, Inc.Inventors: Peter D. Baker, Robert H. Weinmann, Jr., Robert Mercado, Christopher W. Nesselroad, Lucy A. Baker, Gilbert J. Bastien

Patent number: 5551169Abstract: The temperature of air to heat or cool a product (16, 18) is maintained constant at levels which respectively are substantially higher or lower than the goal temperatures at which the respective products are to be stressed. Controllers (68, 70)having temperature/time profiles (72, 74) control the velocity of this higher or lower temperature air, as supplied by closed loops (20, 22) from high and low temperature sources (24, 26) to the products in their environmental stress chambers (12, 14), or bypassed through bypass conduits (50, 52) to maintain or change the temperatures of the products. High and low temperature sources (24, 26) and the product stress chambers (12, 14) may be interconnected by a cross-over arrangement of branches (80, 82, 84 and 86) to economize energy for heating or cooling the air, and to enable both environmental chambers (12, 14) to be interchangeably used for stress heating or cooling and, thus, to avoid movement of a product for the same purpose.Type: GrantFiled: September 28, 1994Date of Patent: September 3, 1996Assignee: Screening Systems, Inc.Inventor: Robert H. Weinmann, Jr.

Patent number: 5154567Abstract: A vibration assembly comprising a housing (12) having a central cavity (20) and a pair of side cavities (22, 24) of radially smaller dimension than that of the central cavity, all of which extends axially about an axis (26) from opposed ends of the central cavity. A piston (50) is housed within the cavities (20, 22, 24) and includes a mass (52) disposed within the central cavity (20) and a pair of supports (54, 56) which are disposed within respective ones of the cavity pair (24, 22) and which extend axially from the mass. The supports (54, 56) have radial dimensions which are substantially the same as those of the pair of cavities (22, 24). The mass (52) and the supports have axial dimensions which are substantially less than those respectively of the central cavity means and of the pair of cavities (20, 22, 24) for enabling the piston (50) to move axially within the cavities.Type: GrantFiled: March 11, 1991Date of Patent: October 13, 1992Assignee: Hughes Aircraft CompanyInventors: Richard L.

Patent number: 4735089Abstract: A shaker table (10) includes a table base (12) mounted upon isolating supports (32) and vibrated by vibrators (34, 36). The vibration is conveyed through and damped in a flexure member (16) comprising pairs (26, 28) of honeycomb layers (18, 20, 22, 24) joined and bonded together by sheets (42) utilizing beads of elastomeric adhesive which space the honeycomb layers apart. A segmented top plate (14) is secured to the topmost honeycomb layer and is divided into a plurality of sections or segments (68-82) for separate resonances. In this way, highly damped vibrational resonances of table top plate (14) are obtained.Type: GrantFiled: December 27, 1985Date of Patent: April 5, 1988Assignee: Hughes Aircraft CompanyInventors: Richard L.
