TODAY’S PATENT – SPRAY CONTROL DEVICE
Today’s patent was invented by Michael Henry Aart Oosterman on 15th June, 2004 bearing patent No. US6749128B1. The invention was assigned to C Dax Ltd.
This invention relates to a control device for spraying which is primarily intended for use with vehicles such as an all-terrain vehicle (“ATV”), small farm tractors, lawn tractors and the like. It is known to provide a spray control system for ensuring that a correct spray application rate is maintained.
A pressure sensor on the control device measures the fluid pressure close to the spray head. A speed sensor enables calculation of vehicle speed. An adjustment device adjusts the delivery of fluid to the spray head. A microprocessor is programmed to calculate from information derived from the pressure sensor and speed sensor spray application rate. After the microprocessor compares the application rate with a stored target application rate, The adjustment mechanism adjusts the pump if necessary so that the pressure of fluid supply reaches the target application rate.
