Abstract
A control system is provided for efficiently regulating the discharge of material from a mobile material distribution device having a product tank or bin, a boom with at least one boom section, a plurality of outlet ducts (e.g., nozzles and/or distribution ports) associated with each boom section, shut-off valves for selectively enabling each boom section, and a selectively-movable control valve for regulating the flow of material to the boom sections. The control system includes a boom sensing input for monitoring whether the shut-off valves are open or closed (i.e., whether the associated boom sections are enabled or disabled), and a processing system for maintaining a substantially stable pressure level between the control valve and each shutoff valve by positionally locking the control valve at its last controlled position upon receiving a signal from the boom sensing input indicating the shut-off valves are closed. Based information received from the boom sensing input, other feedback sensors, and/or manually entered by the user, the processing system selectively regulates the control valve of the material distribution device so as to precisely regulate the material dispersal rate through the enabled boom sections and to provide the material distribution device with certain useful functions including loading, unloading, and agitation features.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
