Patent number: 8843283Abstract: A method and apparatus for controlling a height of an agricultural equipment component is provided. An average crop height is determined. In one embodiment, the agricultural equipment component is controlled to maintain a predetermined distance from a current top of crop level. If a current top of crop level cannot be determined, a virtual top of crop level is calculated using the average crop height value. The agricultural equipment component is controlled to maintain a predetermined distance from the virtual top of crop level. In another embodiment, the agricultural equipment component is controlled to maintain a predetermined distance from current ground level. If a current ground level cannot be determined, a virtual ground level is calculated using the average crop height value. The agricultural equipment component is controlled to maintain a predetermined distance from said virtual ground level. An ultrasonic sensor is also provided.Type: GrantFiled: September 24, 2012Date of Patent: September 23, 2014Assignee: Norac Systems International Inc.Inventors: William Strelioff, Jason Griffith, James Schnaider, Gordon Lee, Dean Hockley

Patent number: 6834223Abstract: A roll control system is provided for controlling a roll position of a boom rotatably coupled to a support frame, the boom comprising left and right wing sections (where the roll of the boom refers to a clockwise or counterclockwise rotation of said boom relative to the support frame). A roll control mechanism is configured for rotating the boom relative to the support frame in response to a roll control signal. Wing section position measuring apparatus is configured for producing a right wing signal correlatable to a distance between the right wing section and a rightwing reference position and a left wing signal correlatable to a distance between the left wing section and a left wing reference position. Boom roll position measuring apparatus is configured for producing a boom roll signal correlatable to a roll position of the boom relative to a boom roll reference position.Type: GrantFiled: February 10, 2003Date of Patent: December 21, 2004Assignee: Norac Systems International, Inc.Inventors: WIlliam Strelioff, Dean Hockley, Gordon Lee
