An electronic data processor comprises a data storage device in communication with the electronic data processor. A control module stored in the data storage device, the control module comprising software instructions for execution by the electronic data processor to change dynamically the fundamental switching frequency of the control signals to reduce electromagnetic noise within a target frequency band if the fundamental switching frequency is equal to or greater than a threshold fundamental switching frequency.

Spread-spectrum control for an inverter for controlling an electric machine

An agricultural permittivity sensor has a drive electrode and a separate sense electrode. Both electrodes have surfaces that face the sensed material and the surfaces are co-planar. The drive electrode receives an excitation signal and generates an electric field that produces a current in the sense electrode. The current is indicative of a test weight of the sensed material.

Agricultural moisture and test weight sensor with co-planar electrodes

A moisture sensor that has a drive electrode and a separate sense electrode is described. Both electrodes have surfaces that face the sensed material and the surfaces are co-planar. The drive electrode receives an excitation signal and generates an electric field that produces a current in the sense electrode. The current is indicative of moisture in the sensed material.
