Abstract:
Die Erfindung betrifft Schwimm- und Tauchhilfe mit einem Fahrzeugrumpf, auf dem sich ein Benutzer auflegt oder aufstellt, mit einem in dem Fahrzeugrumpf angeordneten Strömungskanal, in dem ein von einem Elektromotor angetriebener Propeller mit radial nach außen gerichteten an einem Basisteil des Propellers angebrachten Propellerflügeln, wobei der Elektromotor einen fest angeordneten Motorstator und einen sich drehenden Rotor, der dem Motorstator räumlich zugeordnet ist, aufweist. Dabei ist es vorgesehen, dass der Rotor des Elektromotors mittelbar oder unmittelbar an zumindest ein äußeres Ende zumindest eines Propellerflügels angekoppelt ist und dass der Motorstator zumindest bereichsweise umlaufend um dem Rotor angeordnet ist. Die Motoranordnung ermöglicht einen dynamischen Antrieb der Schwimm- und Tauchhilfe.
Abstract:
This invention relates to a steering device for boats, consisting of a power source, such as an electric motor (1), which is connected to a blade (2), which can be actuated by the motor (1) to move in the water so as to transmit a propulsive force to the boat. The blade is a fin (2) penetrating through the bottom of the boat and connected to the flywheel/lever of the motor, which transmits a rotatory movement (3) to the upper part of the fin (2). The fin is supported and guided in an elongated opening (5) through the bottom (4) of the boat, in which the fin is allowed upward and downward movement while the lower part of the fin describes an onion-shaped rotatory movement (6) under the boat.

Abstract:
The invention discloses an apparatus for reducing maneuverability of a moving ship. The apparatus comprises a propeller fouling element, mountable upon the bow of a second ship. The proper fouling element is deployable towards a propeller of a moving ship. The invention further discloses a rudder engaging component. In one embodiment, the rudder engaging component is U-shaped for accepting a rudder within. The invention also provides a method for reducing the maneuverability of a moving ship, by providing the rudder engaging component and/or the propeller fouling element. The rudder engaging component, when present, is advanced to engage and surround the rudder of the ship. The propeller fouling element is advanced towards a propeller of a ship until it contacts the propeller; thereby reducing the maneuverability of said ship
Abstract:
According to the method for controlling at least one power-shift multi-speed boat transmission in conjunction with a fixed propeller or water jet, the upshift speed is a function of a value which indicates the intended acceleration, especially a function of the regulating speed of the control lever or the speed of modification of the transmission input speed.
Abstract:
The invention concerns a method and system for driving a power engine unit either in a speed control mode or in a load control mode, and changing the control mode. Control mode data of the power engine units is sent and control mode data of other power engine units is received among the units being connected electrically with each other (31). It is determined whether predetermined amount from the total moment of inertia of all power engine units electrically connected with each other is running in the speed control mode after the change of the control mode (32). The power engine unit changes the control mode if the determining step indicates that at least said predetermined amount is running in the speed control mode (33).

Abstract:
An improved personal propulsion device (11) that generally imparts thrust directly to the user (112). The device (11 ) allows hands free control of thrust magnitude and direction so both hands can grasp and control the handlebars and brakes of a bicycle (130), watercraft paddles, ski poles, etc. The device (11) is adjustable vertically, on the user's back, higher to allow sitting in a canoe (131) or wheelchair and lower for standing on skates, skis, kick scooters etc. A user (112) on a bicycle (130) may prefer to lean forward for comfort and aerodynamics, a pivot block (31) compensates and delivers level thrust. A user (112) on a snowboard or skateboard (132) stands oblique to the direction of travel, an adjusting device (19) allows in line thrust. Both user's hands and arms are free to balance, protect others by pushing off or break a fall.
