An agricultural planting machine includes a seed meter configured to meter seed, a transport mechanism configured to transport the seed to a discharge location, and a loader assembly. The loader assembly includes an element having an actuating surface, a hub configured to rotate relative to the actuating surface, and a compartment supported on the hub and configured to receive the seed from the seed meter and to eject the seed into the transport mechanism, the compartment comprising first and second movable elements that are movably coupled to the hub and configured to engage the actuating surface and move relative to the hub based on rotation of the hub relative to the actuating surface.

An object counting device adjusts a signal to account for noise to improve object counting accuracy. A controller receives an electromagnetic radiation (e.g., light) intensity signal from radiation detectors and determines that its value is within a voltage threshold, thereby indicating that no object is passing through the radiation. The controller determines a derivative of the signal and that the derivative is less than a derivative threshold level for at least a predefined time. The controller then updates a base noise floor value to be the value of the radiation intensity signal to account for particles within a path of the electromagnetic radiation to improve an object counting accuracy. In some embodiments, the processor can scale the received radiation intensity signal in accordance with the updated base noise floor value.

An acoustic band-pass filter assembly includes an inlet, a microphone configured to receive acoustic energy from the inlet, and a plurality of resonator chambers disposed in series between the inlet and the microphone and configured to transmit acoustic energy between the inlet and the microphone. Each of the plurality of resonator chambers has a different cross-sectional area.

In one aspect, a calibration method for a seed meter may include controlling an operation of a singulator to apply an initial aggressiveness setting for the singulator. The method may further include controlling the seed meter to rotate a seed transport member of the seed meter relative to a seed chamber of the seed meter containing a plurality of seeds. The method may additionally include performing a calibration cycle, which may include monitoring a first parameter indicative of a number of occurrences of seed multiples as the seed transport member rotates, iteratively adjusting the aggressiveness setting from the initial aggressiveness setting as the first parameter is being monitored, and when the first parameter crosses a first threshold, recording the associated aggressiveness setting as a minimum aggressiveness setting for the singulator.
