Patent number: 6821788Abstract: A specimen collecting and testing device has a housing containing a test membrane. An elongated handle having a foam member is slidably received in the housing. Once the foam member obtains a specimen, the specimen is expelled from the foam member and delivered to a fluid chamber positioned along the test membrane. The device is then positioned horizontally and specimen that collects in the fluid chamber passes through an aperture in the fluid chamber and onto the test membrane located beneath the aperture. The test membrane may then be observed for optical changes in the case of an instant-type test, or removed for further processing. The device is particularly useful for collecting samples of urine or oral fluid for use in drug testing, pregnancy testing and the like; for testing of specimen for any of a variety of analytes such as HIV, hepatitis B, hepatitis C, etc.; and, for collecting samples of DNA for PCR testing.Type: GrantFiled: February 6, 2001Date of Patent: November 23, 2004Assignee: Avitar, Inc.Inventor: Edward Cesarczyk

Patent number: 6729042Abstract: A method is described for enhancing mass and heat transport of fluids in a fine pore structure through an appropriate modulation of the fluid pressure. For example, in an air drying process for a porous material that contains liquid, the air pressure is modulated throughout the volume of the drying chamber. Alternatively, the fluid pressure is modulated in a process stream. As an example, this method can be used for rapid drying of any open porous substances ranging from small pored materials such as aerogels and xerogels, to larger pored substances or articles such as industrial articles, agricultural articles (e.g., densely stacked vegetables, coffee beans, hops and other grains), paper-based products, thin films, pharmaceuticals, cloth, and clothing.Type: GrantFiled: April 16, 2002Date of Patent: May 4, 2004Assignee: Aspen Systems, Inc.Inventor: Kang P.

Patent number: 6698510Abstract: A temperature regulation and flow control device is described. A web of material, e.g., for a wet suit, has a layer of gel particles embedded in a flow control layer, preferably a foam matrix. A water permeable neoprene layer covers the flow control layer and allows water to enter the suit. The flow of water in the suit is regulated by the expansion and contraction of the gel as it undergoes a volume phase transition in response to a change in temperature. When the diver is in cold water, the cold water enters the foam substrate and the gel expands, causing permeability (i.e., flow) to decrease. Flow is restricted in response to cooling, and the foam substrate expands and tightens the fit of the wet suit. In warmer water, an opposite effect occurs, whereby the gel contracts and flow increases. The gel contracts relaxing the fit of the suit. A gel having a particular volume phase transition critical temperature is selected in order to maintain body temperature in a particular environment.Type: GrantFiled: April 24, 2001Date of Patent: March 2, 2004Assignee: Mide Technology CorporationInventors: Marco Serra, Lev Bromberg, Jaco van Reenen Pretorius, Brett P.

Patent number: 6695843Abstract: A bone screw, known per se, with a thread section (2) and a receiving part (5) for receiving a rod (29) to be connected to the bone screw is created. The connection and locking of the connection between bone screw and rod takes place via an outer nut (13). So that the connection has the necessary strength and durability, the outer nut (13) has on the inside a sleeve-shaped element (17), having a predetermined inner measurement, the outer diameter of which is almost identical to or slightly smaller than the diameter of the bore (8), and a pressure element (23) arranged therein. The pressure element (22) (sic) has at its end facing the floor of the bore (8) a first section (26), the outer measurement of which is larger than the predetermined inner measurement and which effects a widening of the element (17) when pressure is exerted on the rod (29) to be received.Type: GrantFiled: December 21, 2001Date of Patent: February 24, 2004Assignee: Biedermann Motech GmbHInventors: Lutz Biedermann, Jürgen Harms
