Abstract: Described herein are systems, methods, and other techniques for controlling a velocity of a construction machine operating within a construction site. Sensor data is captured using one or more sensors of the construction machine while the construction machine is moving at the velocity in a forward or a backward direction. An actual surface of the construction site is estimated based on the sensor data. A deviation between a target surface and the actual surface is calculated. An actual performance metric is calculated based on the deviation. The actual performance metric is compared to a target performance metric to determine a velocity adjustment. The velocity of the construction machine is adjusted by the velocity adjustment.

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: An image cropping technique includes detecting, at a computer system including one or more processors, faces within an image and evaluating, at the computer system, the faces to determine if any of the faces correspond to people within a user's online social network. The technique additionally includes defining, at the computer system, a first crop region including a subset of the faces when at least one face within the subset of the faces corresponds to a first person in the user's online social network and cropping, at the computer system, the image based on the first crop region.

Abstract: A tool control system includes actuators to move the tool, a controller to permit either manual or automatic tool operation, and an output configured to display information pertaining to a position of the tool. In addition, the tool can be moved in either an independent or linked mode, the latter such that during tool operation, both sides of the tool can move substantially in unison with one another, or during system setup, detectors used to ensure coordination with of the tool to a known benchmark can move substantially in unison with one another. The controller can display either single or multiple numbers related to the tool position, and can accept either single or multiple user inputs to move the tool by a user-determined or system-determined amount.

Abstract: A control system controls movement of individual hydraulically moveable ends of a screed head carried by a boom of a machine so as to maintain a selected elevational position between each end of the screed head and a reference in a concrete paving application. One of a pair of elevation receivers is mounted at each end of the screed head, providing a first and second signals indicating the position of the first and second ends of the screed head in relation to the reference. A sensor, mounted on the screed head, senses the orientation of the screed head along its length from the first end to the second end and providing a third signal indicating such orientation.
