A level control output signal is generated for controlling the level of the moveable wings based on a combination of the initial control signal and the compensating signal.

The present disclosure generally relates to methods, systems, apparatuses, and non-transitory computer readable media for processing radar signals of a MIMO radar system. By dynamically accounting for environmental noise both spatially and temporally, systems of the present disclosure can make radar-based systems more accurate and robust against noised-induced false detections, especially with respect to the use of sparse-receivers. More precisely, systems of the present disclosure may first process MIMO radar return data to identify one or more range-Doppler-elevation (RDE) bins exceeding a candidate detection criteria. Each identified candidate detection RDE bin may then be processed by a second search procedure to identify any azimuth bins (of the particular candidate detection RDE bin) exceeding a confirmed detection criteria. Each identified azimuth bin indicates a confirmed detection of a scatterer (e.g., an object) whose azimuth, elevation, range, and Doppler-velocity indicated by the identified azimuth bin and its associated candidate detection RDE bin.

The training module trains the model by generating visual representation and natural language pairs, which are used to train the model.

SYSTEM AND METHOD OF WORK MACHINE IMPLEMENT CONTROL FOR SUBTERRANEAN MAPPING APPLICATIONS
A work machine comprises a machine frame and at least a first implement for working a terrain, a subterranean monitoring unit and a load sensor associated with the first implement, and position sensors respectively associated with the machine frame and the at least first implement. A corresponding method includes, during a subterranean monitoring operation independent of an earth working operation, automatically controlling at least one actuator associated with the first implement to maintain contact of at least one surface of the first implement with a ground surface, the automatic control based at least in part on input signals from the load sensor corresponding to a predetermined range of load values, and generating multidimensional parameters for an electronic worksite map associated with a current location of the work machine, the parameters generated via at least input signals from the subterranean monitoring unit further corresponding with input signals from the position sensors.
A weight of material remaining in a container of an application machine is detected, and operation characteristics corresponding to the operation being performed are also obtained. A time to empty value is calculated that is indicative of a time until the container on the material application machine is empty, based upon the weight of material remaining in the container of the application machine and based the operation characteristics. A control signal is generated based upon the time to empty value.
A battery-electric system for a utility vehicle. The battery-electric system includes a wheel rim and at least one toroidal battery arrangement that is accommodated in a free region of the wheel rim. The at least one toroidal battery arrangement has, in a fastening region that is designed for attachment to a vehicle axle, an interface for releasably establishing a rotation-independent electrical and/or fluidic communication connection to a vehicle-based operating system.

An axle assembly includes an axle configured for rotation by receiving rotational power from the power source and an axle housing containing the axle. The axle assembly further includes a brake disk disposed in the axle housing, coupled to the axle, and configured for rotation upon the rotation of the axle, a lubricant circuit extending from a lubricant circuit inlet axially aligned with the brake disk to a lubricant circuit outlet in the axle housing, and a heat exchanger disposed in the lubricant circuit to exchange heat between lubricant in the lubricant circuit and coolant circulating through the heat exchanger.
A system for operating at least a pair of pumps using a driver. The driver can be coupled to a first portion of a first drive shaft that is not positioned in within an interior area of a thermal fluid tank of a first thermal circuit. A magnetic coupling can couple the first portion to a second portion of the first drive shaft that is within the thermal fluid tank. Rotational displacement of the first portion of the first drive shaft can be translated, via the magnetic coupling, to the second portion of the first drive shaft to drive a first fluid pump. The first portion of the first drive shaft can also be coupled to a second drive shaft by a clutch, the second drive shaft being used to operate a second fluid pump that provides a force for circulating a second thermal fluid of a second thermal circuit.
Systems and methods for warming a battery and operator cab of an electric vehicle. A second thermal fluid is circulated in a second fluid circuit of a primary system, and is heated by an electric heater before being circulated to a first heat exchanger to heat a first thermal fluid in a fluid thermal tank. The heated first thermal fluid is circulated via a first fluid circuit of the primary system and to the battery, or selectively bypasses the battery and returns to the fluid thermal tank. Occasionally, an external system is coupled to a portion of a third fluid circuit residing in the primary system such that heated third thermal fluid from the external system flows to the first heat exchanger. Partially heated second or third thermal fluid can flow to a second heat exchanger such that the remaining heat entrained therein can heat the operator cab.
One or more techniques and/or systems are disclosed for determining appropriate settings and controlling windrower performance based on the constituents of the target crop. Crop condition and constituents can be identified in the field using sensors in/at the windrower implement, such as constituent sensors and/or imaging sensors. An implement controller can receive sensor data from the sensor array and generate crop condition data indicative of a condition of the target crop. The controller can also generate actuator adjustment data indicative of an adjustment to the roller assembly in the windrower implement to meet a target crop dry-down characteristic. One or more actuators can be used to adjust the roller assembly of the windrower implement based at least on the adjustment data, which can be done automatically or by an operator to the roller systems in the implement.
