Latest Patents

One of Kenneth's latest patents is an "Automatic speed control system for a harvesting assembly." This invention focuses on a speed controller system for the gathering unit of a harvesting assembly, where the speed is controlled as a ratio of the ground speed of the harvesting machine. The system features an electronic controller equipped with a ground speed sensor and a speed sensor for the gathering units. The operator can select the desired speed ratio through a ratio selector, allowing the controller to adjust the speed of the gathering unit accordingly. This controller is versatile and can be used with various harvesting assemblies, including platforms with reel or belt pickup gathering units and row crop headers. Additionally, it includes a diagnostic routine that flags problem areas within the system, displaying diagnostic codes in a defined order.

Another notable patent is the "Photoelectric article sensor with facing reflectors." This sensor is designed for counting articles, such as seeds, moving through a conduit. It utilizes an array of infrared LEDs to generate a uniform diffuse beam of radiation that illuminates the cross-sectional volume of the conduit. A planar photo diode detects the beam on the opposite side, while mirrors extend along the conduit to narrow the beam and limit radiation exposure to the photo diode. The signal from the photo diode is processed by a signal processing unit, enabling the sensor to count multiple seeds passing through the beam simultaneously. This unit also compensates for variations in the steady-state photo-diode output and changes in seed size.
