Patent number: 10378569Abstract: A mounting structure for adhesively bonding onto a surface includes a base, an outer face of the base and an inner face of the base. An adhesive injection port is provided on the outer face of the base for supplying an adhesive. A primary adhesive flow path is provided on the inner face of the base. The primary adhesive flow path is in fluid communication with the adhesive injection port and allows the adhesive to flow. Further, a plurality of secondary adhesive flow paths originating from the primary adhesive flow path allow the adhesive to distribute on the inner face.Type: GrantFiled: October 25, 2017Date of Patent: August 13, 2019Assignee: Caterpillar Inc.Inventors: Jeff A. Jensen, Joe J. Every, Aaron K. Amstutz, Steve D. Lundquist

Patent number: 9354034Abstract: A positive location system is disclosed for a locomotive consist including at least two locomotives. The system may include a first locator element on a first locomotive and a second locator element on a second locomotive. Each locator element may include a receiving device and a transmitting device communicatively coupled with each other locator element. Each locator element may be configured to determine its own location, relay information on its location to at least one other locator element on another locomotive, receive location information on the at least one other locator element, and determine its own location relative to the location of the at least one other locator element. Each locator element may also provide location information for the at least one other locator element as though it were the at least one other locator element when the at least one other locator element is non-functional.Type: GrantFiled: March 8, 2013Date of Patent: May 31, 2016Assignee: Electro-Motive Diesel, Inc.Inventors: Steve D. Lundquist, Tom Otsubo

Patent number: 9100838Abstract: A rail system is disclosed. The rail system may have a track including a wireless communication zone and a wired communication zone. The rail system may also have an electrical contact that extends along the wired communication zone. The electrical contact may be configured to transmit electrical energy and a data communication. The rail system may further have a power source electrically connected to the electrical contact. The rail system may additionally have a controller selectively electrically connectable to the electrical contact and a wireless network. The power source may be configured to transmit electrical energy through the electrical contact. The controller may be configured to switch between data communication transmission via the wireless network and via the electrical contact, based at least in part on a location of a rail vehicle within the rail system.Type: GrantFiled: July 29, 2013Date of Patent: August 4, 2015Assignee: Electro-Motive Diesel, Inc.Inventors: Steve D. Lundquist, Harinder Singh Lamba

Method and apparatus for controlling an earthworking implement to preserve a crown on a road surface
Patent number: 5905968Abstract: A method and apparatus for controlling an earthworking implement on an earthworking machine to preserve a crown on the surface of a road, including determining the position of the crown on the road surface, choosing a sloped grade on one side of the crown, positioning the earthworking implement on the sloped grade so that a first end of the earthworking implement is on the road surface. The processor determines a desired position of a second end of the earthworking implement so that the second end overlaps the crown and the earthworking implement does not cut the crown.Type: GrantFiled: September 12, 1997Date of Patent: May 18, 1999Assignee: Caterpillar Inc.Inventors: Michael D. Staub, Louis G. Alster, Steve D. Lundquist
