Abstract: Methods and systems are described for estimating yaw of an implement relative to a machine. The yaw is estimated using gyro signals. The gyro signals may be provided by gyro sensors such as IMUs that are coupled to the implement and machine.

Abstract: An earthmoving machine comprises a sensor, an implement, and control architecture comprising a controller and configured to facilitate movement in response to a signal indicative of a measured implement position and an implement control value comprising a gain value associated with implement speed. The controller is programmed to execute machine readable instructions to generate a noise value that is based on an error between the signal and a target signal, determine whether the noise value is acceptable to lock the gain value, adjust the gain value to control the implement speed when the noise value is unacceptable until the noise value is acceptable, and operate the machine based on the locked gain value.

Abstract: An earthmoving machine comprises a sensor, an implement, and control architecture comprising a controller and configured to facilitate movement in response to a signal indicative of a measured implement position and an implement control value comprising a gain value associated with implement speed. The controller is programmed to execute machine readable instructions to generate a surface-based cost function (SBCF) value based on the signal, determine whether the SBCF value is acceptable to lock the gain value, and generate a noise value that is based on an error between the signal and a target signal when the SBCF value is unacceptable, determine whether the noise value is acceptable to lock the gain value, adjust the gain value to control the implement speed when the noise value is unacceptable until the SBCF value or the noise value is acceptable, and operate the machine based on the locked gain value.

Abstract: A device for spatial positioning systems includes a programmable measurement filter that is dynamically tuned by the device signal processing unit. The signal processing unit analyzes available data including the measurement signal to determine the likelihood that a detected measurement comprises true device movement and adjusts the measurement filter bandwidth accordingly.

Abstract: A laser reference system orients a reference plane of laser light generated by a transmitter so compensation is made for a rake angle between the first and second axes of the transmitter and an alignment axis and an axis perpendicular thereto. The transmitter includes an optical system arranged to generate a laser beam, the optical system projecting said laser beam radially along a rotational arc defined about a central rotational axis, thereby substantially defining a reference plane of laser light, and a positioning arrangement, coupled to said optical system, for adjusting the angular orientation of the optical system with respect to a first transmitter axis and with respect to a second transmitter axis. A detector is arranged to detect reception of the laser beam. The detector includes a generally vertically arranged row of detector elements. The detector further includes a transmitter for transmitting information regarding the location of said laser beam, as detected by said detector elements.
