  • Patent number: 10603550
    Abstract: A handheld propulsion unit for use by a user in and under water is disclosed. The handheld propulsion unit includes a tubular shaped housing assembly having a forward and rearward end. A channel defined by the tubular shaped housing assembly allows a flow of water to move through the tubular shaped housing assembly. At least one frame member connected to the tubular shaped housing attaches an electric motor within the channel such that the electric motor is coaxially aligned with the channel. A propeller coaxially coupled directly to a rotating part of the electric motor eliminates a drive transfer assembly or a drive transfer housing from spanning the channel. Hand grips on the tubular shaped housing assembly are configured for being held by the user and allowing the user to maneuver a thrust provided by the flow of water through the channel when the propeller is operating.

  • Patent number: 8326534
    Abstract: A relative positioning system enabling a user to return to a starting position or some other point on the user's path. The system may include an array of accelerometers. The output from the accelerometers may be integrated to quantify movement of the array. The various movements of the array may be reconstructed to determine a net two or three dimensional translation. The current location of the array may be compared to a reference point to derive at trajectory directing the user to the reference point, such as an originating point. The trajectory may be continuously or periodically updated. Applications may include various displays presenting images, numbers, pointers, paths, vectors, or data by digital screens, watch faces, or other devices integrated with or remote from the processor calculating the vector back to the point of origin.

  • Patent number: 8251007
    Abstract: A restraint system for securing a user on a watercraft, on which the user at least partially rests. The restraint system has a belt strap which is passed around the body of the user. Also, the restraint system has two stepped straps which are fitted onto the belt strap in the area of the stomach of the user and also in the area of the back of the user and are each passed through the step of the user. A connecting strap, one end of which acts on the belt strap in the area of the stomach of the user, can be fitted at its other end to the watercraft. Also, this invention relates to a watercraft having such a belt system.

  • Patent number: 8191494
    Abstract: An underwater dive plane includes a central rotating hub, rotating wing holders on either side of the central rotating hub, and wings attached to the wing holders. The attachment is accomplished by a threaded bolt inserted through the center of the central rotating hub and through the center of the wing holders in a way that permits the wing holders to rotate around the threaded bolt. A rope threaded through a hole in the central rotating hub leads to a watercraft and allows towing a person holding onto the dive plane. The rotating wings allow the diver to control the angle and direction of the dive.
