US Patent:

54590353, Oct 17, 1995

Filed:

Dec 9, 1992

Appl. No.:

7/987678

Inventors:

Robert R. Guerrero - Pasadena CA
Donald E. Rounds - Altadena CA

Assignee:

AMDL, Inc. - Pasadena CA

International Classification:

C12Q 168
C12Q 100
C07K 1500
C07H 1700

US Classification:

435 6

Abstract:

A method is described for identifying and localizing tumors in a patient. The method comprises assaying extracellular fluids, isolated from a patient, for the presence of elevated levels of ring shaped particles (RSP). The assay employs binding labeled RSP specific binding agent to the RSP.

US Patent:

Filed:

Aug 18, 1986

Appl. No.:

6/897601

Inventors:

Donald E. Rounds - Altadena CA

Assignee:

Huntington Medical Research Institute - Pasadena CA

International Classification:

G01N 33544
G01N 33542
G01N 33536

US Classification:

435 5

Abstract:

An immunoassay procedure utilizing a formazan-labeled primary antibody to detect the presence of an antigen is disclosed. The formazan-labeled antibody is dissolved in a test fluid suspected to containing the antigen. A dipstick having a first section on which primary antibodies are bonded and a second section free of primary antibodies and antigens and blocked to prevent bonding of primary antibodies and antigens is immersed in the test fluid and removed after a select period of time. A difference in color between the first and second sections indicate the presence of the antigen.

Filed:

Apr 19, 1999

Appl. No.:

9/294078

Inventors:

Donald E. Rounds - Corvallis OR

International Classification:

H02K 3700
H02K 4900

US Classification:

310 46

Abstract:

A magnetically operating device comprises a driven magnet having magnetically opposite poles which are separated, a driver magnet having magnetically opposite poles, and the magnets are mounted for relative movement to maintain one of the driver magnet's poles substantially equidistant from the poles of the driven magnets as the driven magnet moves relative to the driver magnet. A first rotor may mount the driven magnet or magnets for rotation about a first axis, and a second rotor may mount the driver magnet or magnets for rotation about a second axis, and such axes are typically non intersecting and skewed, the rotors being intercoupled. A source of torque such as a motor may be coupled to the second rotor to effect torque input to the second rotor.
