Patent number: 8564295Abstract: At least one antenna array including three mutually orthogonal antennas each sharing a common center point senses an electromagnetic signal emitted by a buried object such as a utility line, pipe or sonde. A circuit at least partially mounted in a housing is connected to the array and determines a location of the buried object by measuring signal strength and field angles in three dimensions without having to align the antenna array relative to the buried object while eliminating nulls and false peaks. A graphical user interface (GUI) has user-friendly icons, symbols, menus, numbers and graphical and auditory representation of signal strength. A plurality of different underground objects can be simultaneously detected and their different locations can be simultaneously indicated to a user via audible sounds and/or visual images on a display.Type: GrantFiled: November 1, 2010Date of Patent: October 22, 2013Assignee: Seescan, Inc.Inventors: Mark S. Olsson, Jeffrey A. Prsha, Dawn E. Shaffer, Ray Merewether, Michael J. Martin, Bradley D. Barnicoat, David A. Cox, Thomas R. Kolb

A graphical user interface (GUI) has user-friendly icons, symbols, menus, numbers and graphical and auditory representation of signal strength. A SEARCH view indicates signal strength by showing a rotating strength indicator, a trace mode MAP view in which line location is shown by a line that moves side-to-side, and a sonde mode MAP view in which sonde location is shown by a moving line, pole and equator.Type: GrantFiled: October 12, 2010Date of Patent: October 11, 2011Assignee: SeekTech, Inc.Inventors: Mark S.

Patent number: 6545704Abstract: A video pipe inspection system includes a video camera head with an optical sensor connected to a circuit for generating a video image signal representing real time images of scenes in view of the optical sensor. The system further includes a push reel that is rotatably mounted on a support frame. An elongate push cable is normally stored in continuous turns in the push reel. The push cable has a distal end operatively connected to the video camera head and a proximal end operatively connected to a central hub of the push reel. The push cable includes at least one conductor for conveying the video image signal from the camera head. The push cable has a predetermined resiliency and flexibility to permit the push cable to be unwound from the push reel in order to force the camera head a substantial distance down a length of pipe having one or more tight turns.Type: GrantFiled: July 7, 1999Date of Patent: April 8, 2003Assignee: Deep Sea Power & LightInventors: Mark S.
