Abstract: A method of spreading granular fertilizer includes driving a small framed truck over an electronically mapped area that is in need of granular fertilizer. As the small framed truck is driven over the mapped area, a GP S sensor is read to determine the location of the small framed truck on the mapped area. An electronic control determines the application rate of granular fertilizer needed to the left of the truck and the application rate of granular fertilizer needed to the right of the truck in relation to the location of the truck on the mapped area. The method includes dispensing left and right amounts of granular fertilizer from a hopper carried on the truck, with the left and right amounts being separately dispensed at rates determined in the determining step. Apparatus to carry out the method is also disclosed.

Abstract: A system and method of playing recorded content on a DVD player employs software instructions on a DVD storage medium to control a DVD-Video player to make pseudo-random selections of content items from the DVD storage medium. Each content item may include an individual video sequence or a string of video sequences. Each content item is associated with a respective identification codes, such that each content item is associated with a corresponding identification code that is different from the identification codes of other content items. The DVD player controller is controlled to select, by pseudo-random selection or generation, at least one of the identification codes from the plurality of identification codes. The DVD player controller may be controlled to perform that pseudo-random selection or generation with software stored on (and read from) the DVD storage medium.
