Publication number: 20060195014Abstract: A capsule is coupled to a tether that is manipulated to position the capsule and a scanner included within the capsule at a desired location within a lumen in a patient's body. Images produced by the scanner can be used to detect Barrett's Esophagus (BE) and early (asymptomatic) esophageal cancer after the capsule is swallowed and positioned with the tether to enable the scanner in the capsule to scan a region of the esophagus above the stomach to detect a characteristic dark pink color indicative of BE. The scanner moves in a desired pattern to illuminate a portion of the inner surface. Light from the inner surface is then received by detectors in the capsule, or conveyed externally through a waveguide to external detectors. Electrical signals are applied to energize an actuator that moves the scanner. The capsule can also be used for diagnostic and/or therapeutic purposes in other lumens.Type: ApplicationFiled: February 28, 2005Publication date: August 31, 2006Applicant: University of WashingtonInventors: Eric Seibel, Michael Kimmey, Richard Johnston

Publication number: 20060077121Abstract: Apparent distance of a pixel within an optical field of view is determined. Incoming light is scanned along a raster pattern to direct light for a select pixel onto a light distance detector. The distance is sampled for each pixel or for a group of pixels. The light distance detector includes a concentric set of rings sensors. The larger the spot of light corresponding to the pixel, the more rings are impinged. The diameter of the spot is proportional to the distance at which the light originated (e.g., light source or object from which light was reflected). Alternatively, a variable focus lens (VFL) adjusts focal length for a given pixel to achieve a standard spot size. The distance at which the light originated correlates to the focal length of the VFL.Type: ApplicationFiled: November 28, 2005Publication date: April 13, 2006Applicant: University of WashingtonInventors: Charles Melville, Michael Tidwell, Richard Johnston, Joel Kollin

Publication number: 20050106363Abstract: Using printing and coating of non-currency grade paper, authentication of coupons or other documents is provided for minimal cost. By coating the document with a UV/EB material having a desired trace chemical residual content (e.g., substantially no starch), the authenticity of a coupon or document is checked using already widely distributed counterfeit currency detection pens. Since many retail establishments rely on iodine or potassium permanganate solution testing of currency, by providing a coating that reacts differently than non-currency grade paper, the same solution is used to verify the authenticity of coupons or other documents without the costs of using currency grade paper. The results of the test for authenticity are easily visible, allowing a coupon issuer to reimburse retail establishments only for coupons or documents that have been verified and shown to be authentic. By refusing to redeem or reimburse for untested or counterfeit coupons, losses due to counterfeiting may be reduced.Type: ApplicationFiled: November 13, 2003Publication date: May 19, 2005Inventors: Bruce Williams, Scott Goldstein, Richard Johnston

Publication number: 20040239200Abstract: A single phase synchronous AC motor includes a laminated iron stator (1) carrying a single phase winding (3, 4) and a permanent magnet rotor (2) located within a stator bore (5). The stator bore is elongate in shape and is generally symmetrical about a minor axis (13) and a major axis (14). A permanent magnet reluctance torque smoothes out the twice electrical frequency torque pulsation due to the single phase winding. Substantially constant torque is obtained at all rotor positions when rated load torque is applied. The motor may be designed such that constant torque is achieved for any rate value of load torque corresponding to a factional value of the permanent magnet reluctance torque. The motor may be designed to obtain a useful ratio of pullout to rated torque for operation from a mains AC supply.Type: ApplicationFiled: March 8, 2004Publication date: December 2, 2004Inventor: Richard Johnston Strahan
