  • Patent number: 8967035
    Abstract: A sensor coupler adapted to operatively connect a sensor to a piston-cylinder assembly. The sensor coupler includes a first end member and a second end member. The first end member is disposed on a port of the piston-cylinder assembly, in communication with the sensor, and the second end member is disposed in a cylinder chamber of the piston-cylinder assembly. Further, one or more cables are extending between the first end member and the second end member. The one or more cables are configured to transmit signals indicative of a position of a piston in the piston-cylinder assembly to the sensor. The sensor coupler further includes a biasing member to connect the first end member and the second end member.

  • Patent number: 8807261
    Abstract: An articulation control system is disclosed for use with a mobile machine having a traction device. The articulation control system may have a speed sensor configured to generate a first signal indicative of a travel speed of the mobile machine, a steering angle sensor configured to generate a second signal indicative of a steering angle of the traction device, and an articulation actuator configured to articulate a front frame of the mobile machine relative to a rear frame of the mobile machine. The articulation control system may also have a controller in communication with the speed sensor, the steering angle sensor, and the articulation actuator. The controller may be configured to track a travel path of the front frame based on the first and second signals, and to regulate operation of the articulation actuator to cause the rear frame to follow the travel path of the front frame.

  • Publication number: 20130115034
    Abstract: A sensor assembly is disclosed for a pin connection of a machine linkage, such as that found on an excavator or backhoe loader, the sensor assembly including a sensor associated with a sensor housing that receives the pin, and a connector assembly that connects the sensor housing to a frame element, wherein the connector assembly is configured to allow the sensor housing to move relative to the frame element. The sensor assembly may be positioned within one of the members of the linkage.
