Abstract: A method and system for adjusting inputs to an agriculture field to improve crop performance. Data are gathered for a field divided into zones, which may be sector-shaped or otherwise. These data include field characteristics, grower inputs, and yield. Statistical techniques are applied to (1) identify grower inputs that correlate with crop performance; (2) identify zones that may benefit from adjustments to one or more grower inputs; (3) predict improvements in crop performance that may result from adjusting one or more grower inputs for a particular zone; (4) suggest an adjustment to one or more grower inputs for a particular zone; (5) analyze actual effects of applying adjustments to grower inputs for a particular zone; (6) determine whether a zone may benefit from further tuning one or more grower inputs; and (7) suggesting tuning adjustments to one or more grower inputs for a zone. A method and system for computing “Sure Pressure”, i.e.

Abstract: A controlled release parking brake system is disclosed that comprises a parking brake lever (either foot or hand operated), a dampening system, at least one cable and a connection to a conventional braking system operated by the cable. The disclosed assembly can be employed to control the release of a parking brake on a wide range of vehicles such as passenger cars, all terrain vehicles, lawn equipment and tractors, trucks (e.g., Class 5-7), utility cars, among other applications wherein it is desirable to have controlled release of mechanical energy or force.
