Abstract: A system for an agricultural harvester can include a topper assembly including a cutting disk configured to severe an upper portion of a crop. A sensor system including a first sensor may be configured to capture crop data associated with the crop. A computing system is operably coupled with the topper assembly and the sensor system. The computing system includes one or more processors and one or more non-transitory computer-readable media that collectively store instructions that, when executed by the one or more processors, configure the computing system to receive an input related to a defined offset, obtain the crop data from the sensor system, determine a target of the crop based at least partially on the crop data, and position the cutting disk at a cutting position along the crop.

Abstract: A power transistor includes an ambient temperature input, a local temperature sensor, an array of transistor cells, and a thermal feedback circuit. The ambient temperature input is configured to receive an ambient temperature signal that is representative of an ambient temperature of the power transistor. The array of transistor cells has a control input. The local temperature sensor is configured to provide a local temperature signal that is representative of a temperature of the array of transistor cells. The thermal feedback circuit is coupled to the ambient temperature input, the local temperature sensor, and the control input. The thermal feedback circuit is configured to modulate a control signal provided at the control input based on a difference between the ambient temperature signal and the local temperature signal.

Abstract: A voltage selector circuit includes a voltage comparator, a multiplexer, and an adaptive current bias generator. The voltage comparator receives first and second input voltages, and outputs a comparator signal based on the first and second input voltages. The multiplexer selects a larger of the first and second input voltages in time based on first comparator signal. The adaptive current bias generator generates a bias current for the voltage comparator during a transition from a first state to a second state. The first input voltage is continuously larger than the second input voltage during the first state, and the second input voltage is continuously larger than the first input voltage in the second state. The bias current during the transition has a time-varying current level that is proportional to a time-varying difference between the first input voltage and the second input voltage during the transition.
