  • Patent number: 11555278
    Abstract: A paving machine may include a frame, a screed, sensor devices, and a control unit. The screed may include a main section, a first extension, and a second extension. The sensor devices may output a first sensor signal corresponding to a position of the first extension and a second sensor signal corresponding to a position of the second extension. The control unit may receive the first and second sensor signals, determine a screed width based on the first and second sensor signals, receive location data corresponding to a location of the paving machine, determine locations of the first and second extensions based on the screed width and the location data, generate a boundary map based on the locations of the first and second extensions, and cause an action to be performed based on the boundary map.

  • Patent number: 11149405
    Abstract: A grade control indicator assembly is disclosed. The grade control indicator assembly may include a keypad to control one or more functionalities of a machine, where the keypad includes a set of grade control light indicators integrated into the keypad, and where the set of grade control light indicators includes a first subset of grade control light indicators for indicating a grade of the machine with respect to a first side of the machine and a second subset of grade control light indicators for indicating the grade of the machine with respect to a second side of the machine.

  • Patent number: 10633805
    Abstract: Systems and methods for implementing a machine control system in a construction machine having an implement with an extender. The machine control system may include an acceleration sensor mounted to the implement and a processor configured to perform various operations. The operations may include determining that the extender is not moving and in response operating under a first control scheme. Operating under the first control scheme may include receiving acceleration data from the acceleration sensor, generating an estimated slope of the implement based on the acceleration data, and modifying a slope of the implement based on the first estimated slope by causing movement of at least one tow arm. The operations may also include determining that the extender is moving and in response operating under a second control scheme. Operating under the second control scheme may include maintaining the slope of the implement substantially constant.

  • Publication number: 20030176907
    Abstract: A ventricular stylet and pacing lead having a novel, modified curve shape enabling easy placement and positioning, a uniquely oversized torque handle enabling efficient manipulation and an internally carried, arcuately barbed tip enabling minimally traumatic fixation within the heart, thereby decreasing total implant time, decreasing ventricular lead placement time and facilitating better apical placement in the right ventricle, thus lowering thresholds.
