Abstract: A self-leveling crop spraying apparatus is carried by a prime mover, The crop spraying apparatus includes first and second masts, and first and second opposed pendulum arm frame members slidingly engaged to the fast and second masts. A pendulum arm extends through the first and second opposed pendulum arm frame members. The first and second pendulum assemblies are coupled to opposed ends of the pendulum arm, and a carriage assembly is carried by the first and second pendulum assemblies. The carriage assembly is rotatable relative to the first and second masts and first and second opposed pendulum arm frame members.

Abstract: A crop spraying vehicle includes a mast arm having a mast arm sleeve slidingly engaged with it. A crop spraying apparatus is coupled to the mast arm sleeve with a pendulum arm. The engagement between the mast arm and mast arm sleeve restricts and allows the transverse and longitudinal rotation, respectively, of the crop spraying apparatus.

Abstract: The present invention is directed to touch sensors with arrays of switches (e.g., diodes or transistors) that can be used to selectively apply voltage gradients across a resistive touch regions of the touch sensor substrate. Touches on the touch sensor can then be sensed by measuring the voltage at the touch location on the resistive touch region. The switch arrays take the form of strips of switches that can be cut from a prefabricated reel or a sheet and applied to the touchscreen substrate.

Abstract: The crop spraying device of the present invention is disclosed herein comprises a crop sprayer boom on a pendulum wherein the pendulum pivot is attached to a moving vehicle. The crop sprayer boom may comprise a center section with a spray boom attached on either side. The pendulum arm length is selected or adjusted to produce a natural frequency of pendulum oscillation that is not harmonic with the principal modal frequencies of the crop sprayer boom structure or its principal components. The length of the pendulum arm may be adjustable. The pendulum arm length may be selected to avoid harmonics of the modal vibrations of the sprayer boom when dry, when the spray lines are full, and when the spray heads on the boom are spraying. In a particular embodiment, harmonics of the principal frequencies of the vehicle suspension, sprayer tank slosh, and sprayer pump are also avoided. An apparatus for adjusting the pendulum length without changing the height of the boom above the crop is included in the disclosure.
