Abstract
The laser guidance assembly ( ) includes a platform ( ) supported on a vehicle. A mirror support ( ) is rotatably supported by the platform ( ) for rotation about a vertical axis. A first mirror ( ) is supported by the mirror support ( ) for rotation about the vertical axis. The assembly ( ) further includes a diode ( ) attached to the platform ( ) for emitting a laser beam ( ) in a laser path ( ). The assembly ( ) is characterized by having a pivotal connection ( ) between the first mirror ( ) and the mirror support ( ) for allowing oscillation of the first mirror ( ) about a horizontal axis ( ) relative to the platform ( ) and the mirror support ( ). The assembly ( ) has a second mirror ( ) supported by the platform ( ) and fixed relative to the platform ( ) for reflecting a reflected laser beam ( ) from the first mirror ( ). The second mirror ( ) has a filter section ( ) and reflective section ( ) for allowing the laser beam ( ) to pass through and for reflecting the reflected laser beam ( ). A processor ( ) integrates a first signal ( ) which is the reflected laser beam ( ) signal, an oscillation signal ( ) for the position of the first mirror ( ) about the horizontal axis ( ), and a rotational signal ( ) for the position of the first mirror ( ) about the vertical axis ( ) to determine the precise location of a lawn mower upon which the assembly ( ) is mounted.
