Patent number: 8022307Abstract: A flexible, fabric-based circuit comprises a non-conductive flexible layer of fabric and a conductive flexible layer of fabric adjacent thereto. A non-conductive thread, an adhesive, and/or other means may be used for attaching the conductive layer to the non-conductive layer. In some embodiments, the layers are attached by a computer-driven embroidery machine at pre-determined portions or locations in accordance with a pre-determined attachment layout before automated cutting. In some other embodiments, an automated milling machine or a computer-driven laser using a pre-designed circuit trace as a template cuts the conductive layer so as to separate an undesired portion of the conductive layer from a desired portion of the conductive layer. Additional layers of conductive fabric may be attached in some embodiments to form a multi-layer construct.Type: GrantFiled: July 3, 2007Date of Patent: September 20, 2011Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Andrew W. Chu, Justin A. Dobbins, Robert C. Scully, Robert C. Trevino, Greg Y. Lin, Patrick W. Fink

Patent number: 7410485Abstract: A miniature microwave antenna is disclosed which may be utilized for biomedical applications such as, for example, radiation induced hyperthermia through catheter systems. One feature of the antenna is that it possesses azimuthal directionality despite its small size. This directionality permits targeting of certain tissues while limiting thermal exposure of adjacent tissue. One embodiment has an outer diameter of about 0.095? (2.4 mm) but the design permits for smaller diameters.Type: GrantFiled: January 14, 2005Date of Patent: August 12, 2008Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Patrick W. Fink, Greg Y. Lin, Andrew W. Chu, Justin A. Dobbins, G. Dickey Arndt, Phong H. Ngo

Patent number: 6816117Abstract: System and methods are disclosed for employing one or more radiators having non-unique phase centers mounted to a body with respect to a plurality of transmitters to determine location characteristics of the body such as the position and/or attitude of the body. The one or more radiators may consist of a single, continuous element or of two or more discrete radiation elements whose received signals are combined. In a preferred embodiment, the location characteristics are determined using carrier phase measurements whereby phase center information may be determined or estimated. A distributed antenna having a wide angle view may be mounted to a moveable body in accord with the present invention. The distributed antenna may be utilized for maintaining signal contact with multiple spaced apart transmitters, such as a GPS constellation, as the body rotates without the need for RF switches to thereby provide continuous attitude and position determination of the body.Type: GrantFiled: May 24, 2001Date of Patent: November 9, 2004Assignee: The United States of America as represented by the United States National Aeronautics and Space AdministrationInventors: Patrick W. Fink, Justin A. Dobbins
