Patent number: 8996258Abstract: Methods and apparatus for automatically adjusting the angle of a rotatable side view mirror of an articulated tractor and trailer includes transducers attached to the tractor for transmitting signals toward the trailer and for receiving signals reflected by the trailer. The transducers have a substantially symmetrical arrangement about a centerline of a linear transducer bar attached to the tractor and each has an angular orientation substantially dissimilar to adjacent transducers on a same side of the centerline. A control circuit sequentially activates ones of the transducers such that only a single transducer transmits signals at any given time. Thereafter, the control circuit only processes reflected signals received by the emitting transducer. The control circuit calculates an angle between the tractor and trailer and causes the mirrors to rotate. Transducer calibration and mirror adjustment relative to a zero position set by a driver are also contemplated.Type: GrantFiled: October 30, 2006Date of Patent: March 31, 2015Assignee: Full-View-Matic, Inc.Inventors: Hongwei Liu, Barry Davignon

Publication number: 20050192592Abstract: A self-tensioning handle for use with endoscopic devices is disclosed. The handle may have mounting features for mounting a sheath and a control rod from an endoscopic device, such as a grasper or a retrieval basket. One mounting feature, such as a pin vise to hold a sheath, may be mounted in a distal portion of the handle, nearer a patient. Another mounting feature for a control rod or cannula of the endoscopic device is preferably mounted in a proximal portion of the handle. The handle is assembled with a tension or a pre-load so that a surgeon is not required to continually grip and compress the handle to retain a sample in the retrieval basket or other end-effector used with the handle.Type: ApplicationFiled: February 24, 2005Publication date: September 1, 2005Inventors: Gary Butler, Thomas Foster, Frank Fischer, Nicholas Terwiske, John Ward, Richard Stamper, David Radue, Elizabeth Purdy, Robert Davignon, Barry Davignon, Ronald Hofmann

Publication number: 20040199185Abstract: Sutures can be reliably applied to the tissue of sensitive organs in a predetermined and limited depth with minimal surgical skills through the use of a curved suture needle and a suture control apparatus. The suture control apparatus, which can be adjustable, comprises a pair of needle guides that are separated by a space, and a locator surface for engagement with the suture-receiving tissue in the space between the needle guides, with the pair of needle guides and locator surface being preferably carried by a handle. Preferably, the pair of needle guides are curved to provide a radius of curvature substantially equal to the radius of curvature of the curved suture needle.Type: ApplicationFiled: February 5, 2004Publication date: October 7, 2004Applicants: Rose-Hulman Institute of Technology, Rose-Hulman VenturesInventor: Barry Davignon
