Abstract: A control system for an agricultural tillage implement includes a controller configured to receive a first pressure sensor signal indicative of a first fluid pressure within a rolling basket cylinder and a second pressure sensor signal indicative of a second fluid pressure within a wheel frame actuator. The rolling basket cylinder is configured to couple to a main frame and to a rolling basket frame, and the wheel frame actuator is configured to control a position of a wheel frame relative to a hitch assembly. The controller is also configured to decrease a target fluid pressure in response to the second fluid pressure being below a minimum wheel frame actuator pressure threshold, and the controller is configured to control a tilt force applied to the main frame to maintain the first fluid pressure within a range of the target fluid pressure.

Abstract: A control system for an agricultural tillage implement includes a controller configured to receive a first signal indicative of a target depth of a rear row of disc blades and a second signal indicative of a redirection amount and a redirection direction. The controller is configured to determine a target pitch angle adjustment based on the amount and direction, and the controller is configured to control a tilt actuator to control a tilt force applied to a main frame, a wheel actuator to control a position of a wheel relative to a hitch frame, and a rolling basket cylinder to control a position of a rolling basket relative to the main frame based on the target pitch angle adjustment, the target depth of the rear row of disc blades and one or more inverse kinematic relationships to establish a target penetration depth of a front row of disc blades.

Abstract: A finishing tool control system for an agricultural implement may include a controller communicatively coupled to a first and a second sensor. The controller is configured to control a height of a finishing tool above a soil surface. Further, the first sensor is configured to output a signal indicative of a height of a main frame of the agricultural implement above the soil surface. In response to determining that a height increase of the main frame exceeds a threshold height adjustment, the controller increases the height of the finishing tool. The second sensor is configured to output a signal indicative of the height of the finishing tool of the finishing assembly above the soil surface. Moreover, in response to determining that a height of the finishing assembly above the soil surface is less than a threshold value, the controller increases the height of the finishing tool.

Abstract: A method for measuring the activity of one or more excitable cells, such as neurons, in a target tissue is provided. The present method may include measuring the activity of individual, selected excitable cells by projecting one or more three dimensional (3D) multi-focal laser light patterns into a target tissue containing excitable cells adapted to emit cellular electrical activity—sensitive fluorescence, to generate a multiplexed 2D diffraction pattern of fluorescence emitted by the neurons, and resolving the multiplexed 2D diffraction pattern. Also provided herein is a system configured to perform the present method, the system including a microscope configured to project one or more 3D multi-focal laser light patterns into a target tissue using a spatial light modulator and a mirror galvanometer, and a microlens array and an image detector to record individual and multiplexed 2D diffraction patterns of light emitted from the target tissue.

Abstract: A system and method for enabling a machine to drive through its parking brake when in first gear include detecting that the machine transmission is in its lowest gear in a selected direction, that the machine parking brake is activated, such that the machine is stationary, and that the throttle setting of the machine exceeds a predetermined throttle threshold value. In this state, one or more auxiliary loads of the machine are dropped to provide additional torque to the ground engaging elements of the machine, such that there is sufficient torque to drive the machine through the parking brake.

In the inverted position, the sample container holder is configured to flush the sample container with hydraulic fluid so as to flush away any contaminates that may be present. In the non-inverted position, the sample container holder is configured to fill the sample container with hydraulic fluid.

Abstract: A method is provided for determining a global mask value for filtering incoming messages in a CAN environment having a predetermined number of match registers, where the global mask value has one or more bits. A set of incoming messages to be identified is established. Each of the one or more bits in the global mask value is set to a first digital value. The following steps are repeated until the set of incoming messages to be identified fits within a predetermined number of match registers: adding a don't_care bit to the global mask value and determining a best position for the added don't_care bit. The don't_care bit is represented by a second digital value in the best position.
