  • Patent number: 11071427
    Abstract: A handheld power tool comprises a cruise control actuator (22), which is mechanically connected to a controller input actuator (27) so as to variably move the controller input actuator (27) in a trigger direction (T) based on the position of the cruise control actuator (22). The cruise control actuator (22) is movable between a plurality of different, stable cruise speed positions, in which the cruise control actuator (22) is connected to said controller input actuator (20) in a unidirectional manner to allow a trigger (20) to move the controller input actuator (27) even further in the trigger direction (T) without moving the cruise control actuator (22). The cruise control actuator (22) is also movable to an “OFF” position in which it mechanically blocks the trigger (20) from moving the controller input actuator (27) in the trigger direction (T). Suggested figure for publication.

  • Patent number: 7666040
    Abstract: Enhanced watercraft performance is provided by combinations of one or more inboard swivel propulsion drives and hull tunnels. A tunnel at the hull centerline with specific features provides performance advantages for a center swivel propulsion drive. Use of front propeller based traction propulsion is particularly advantageous in the swivel drive systems and allows the use of tunnels with improved tunnel conformations. Advantages of the traction swivel drive arrangements include minimization of hull space with smaller engine room volume, greater propulsion efficiency and improved watercraft handling.
