  • Patent number: 11253956
    Abstract: A structural member includes a body having a first surface, a second surface, and an end surface at an end portion of the structural member. The end portion of the structural member includes a root protrusion extending radially outward from the second surface of the structural member along a root protrusion radius to an outer end of the root protrusion to define a root protrusion height extending from the second surface of the structural member to the outer end of the root protrusion. The root protrusion further includes a root protrusion width extending between an inner edge and an outer edge of the outer end of the root protrusion. The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region isolated beyond and away from a root stress flow path propagated through the body of the structural member.
    Type: Grant

  • Patent number: 9243381
    Abstract: An erosion monitoring system is disclosed for use with a machine. The erosion monitoring system may have an ultrasonic sensor embedded within a replaceable cutting edge of a ground engaging tool connectable to the machine. The erosion monitoring system may also have a wireless communication element associated with the ultrasonic sensor, and a controller mountable onboard the machine in communication with the ultrasonic sensor via the wireless communication element. The controller may be configured to monitor a wear rate of the cutting edge based on signals from the ultrasonic sensor.

  • Publication number: 20150034222
    Abstract: A non-pneumatic tire may include a support structure having an inner circumferential portion configured to be associated with a hub. The tire may further include a tread portion associated with an outer circumferential portion of the support structure. The tire may also include at least one sensor associated with at least one of the support structure and the tread portion and configured to generate signals indicative of at least one characteristic associated with at least one of the support structure and the tread portion. The tire may further include a receiver associated with at least one of the support structure and the tread portion and configured to receive signals from the at least one sensor. The tire may also include a transmitter associated with at least one of the support structure and the tread portion and configured to transmit the signals to a location remote from the tire.
