Patent number: 6372514Abstract: Test strip device for accepting a liquid sample and forming an even fluid front across the test strip. When the sample is applied to a contacting surface, it runs down the surface where it collects between the contacting surface and a slope surface. As the sample collects, it evenly reaches fluid flow contact with an absorbent membrane. As a result, the sample forms an even fluid front across the membrane, improving the performance of the test strip device. Methods for using the device to accept a sample and to detect an analyte in the liquid sample are also provided.Type: GrantFiled: September 18, 1998Date of Patent: April 16, 2002Assignee: Syntron Bioresearch, Inc.Inventor: Jin Po Lee

Patent number: 5980886Abstract: A combination of retroviral and adenoviral vectors are used for high efficiency gene transfer into hepatocytes, resulting in long term gene expression. Hepatocytes are transduced in vivo with a recombinant adenovirus vector that expresses a molecule capable of inducing hepatocyte regeneration, such as urokinase plasminogen activator (uPA) or tissue plasminogen activator (tPA), resulting in a high rate of liver regeneration. During the regenerative phase, ex vivo or in vivo retroviral-mediated gene transfer into hepatocytes results in greater transduction efficiencies. The compositions and methods thus provide new means for gene therapy, and transgenic non-human animals useful in developing new therapeutic and preventative agents.Type: GrantFiled: March 17, 1997Date of Patent: November 9, 1999Assignee: University of WashingtonInventors: Mark A.

Patent number: 5594841Abstract: A bare eyed stereogram based on continuous tone, non-random dot art and a process for making the stereogram. A computer implemented process for making the stereogram uses a computer system having a central processing unit, memory, storage, a user interface, an edit program and display means. The art is input to the system in the form of repeating bands of picture elements in a stereogram base. The picture elements have assigned information, and depth information as well. Below a threshold value, new information is assigned by the method of smear. At or above the threshold value, information is provided by a number of techniques which import the information values of picture elements outside the stereogram base. Preferably some of the information is color information and the external color information values are altered to blend with colors in the surrounding base. A process for making a stereogram with wide repeating bands that can be viewed at a distance is shown.Type: GrantFiled: December 27, 1993Date of Patent: January 14, 1997Inventor: Stephen A. Schutz
