  • Mower trimmer combination for facilitating simultaneous mowing and edge trimming in a single pass
    Patent number: 7877971
    Abstract: A trimming system for a user-operated ground vehicle capable of performing mowing and trimming operations. The system includes a drive operatively coupled to a drive system of the vehicle having the trimming system mounted thereon, and a trimming unit operatively coupled to the drive for performing edge trimming operations. The drive may include at least one driven pulley operatively coupled to a drive pulley of the vehicle for driving the trimming unit. The drive pulley may be coupled to a mowing unit and the trimming unit to either selectively or simultaneously drive the mowing and trimming units. A guide wheel may be mounted on the vehicle adjacent the trimming unit for maintaining the trimming wires of the trimming unit at a predetermined distance from a stationary object during performance of edge trimming operations.

  • Depopulated programmable logic array
    Patent number: 7055125
    Abstract: A programmable logic array (PLA) in accordance with the invention achieves a maximum amount of depopulation of programmable connections while still implementing a logic function and maintaining flexibility for future reprogramming. In addition, a PLA in accordance with the invention can be built so that no matter what functionality is programmed, performance characteristics for the device are maintained. Further, a PLA in accordance with the invention does not require a regular array structure.
