Abstract: The present invention discloses a boat motor trolling attachment for use in conjunction with a boat motor and propeller to achieve effective trolling speeds. The boat motor trolling attachment includes a frame, defining an opening, and attached to a mounting bracket which is secured to the boat motor. Two springs are attached between the frame and the mounting bracket so as to bias the frame into a trolling position wherein the frame is disposed in a plane perpendicular to an axis defined by the propeller. Four control members are disposed horizontally across the opening and rotatably fixed to the frame so that a outflow of water impinging on the control members when the boat motor is in a forward gear automatically causes the control members to rotate in the frame so as to substantially close off the opening and form a continuous surface. The outflow of water generated by the propeller acts on the continuous surface and is transmitted thereby to the boat so as to resist forward motion of the boat.

Abstract: To provide an expanded computer desktop working area, a forking driver is removably inserted logically between a graphical device interface program and a plurality of display device driver programs driving a plurality of computer monitor display screens. When inserted, the forking driver configures parameters for the screens to recognize capabilities common to the screens while also preserving significant capabilities of one of the screens representing a primary screen. The forking driver intercepts a function call directed to the device driver program corresponding to the primary screen and processes the function call to cause one or more of the device driver programs to change one or more screens in a manner consistent with the expanded working area.
