Abstract: The present invention relates to isolated polypeptides having D-psicose 3-epimerase activity and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

Abstract: An electronic control system is provided to permit one-person loading and unloading of a vessel from a trailer. The control moves the vessel using bow, stern and fore/aft thrusters that are supplied by the boat manufacturer. Operator inputs to the system controller of the instant invention consist of one or more multi-axis joysticks and a multi-axis foot pedal that are mounted onboard the vessel and a hand-held remote control that permits owner control of the vessel while standing on shore. For one-person unloading and loading of the vessel from and to a trailer, the owner may, using the remote control, drive the vessel off of the trailer to a remote location in the water, park and have the vessel maintain its position with respect to GPS satellites, and call for the vessel to return to the launch point using location data that was previously recorded by the system control.

Abstract: The boat control system is a propulsion system for controlling the direction of passage of a vessel underway at low speeds. Six thruster nozzles are installed around the hull so that, used individually or in combination, the boat can be maneuvered forward, backward, laterally or turned on its axis. Each impeller is driven by a water-cooled reversible DC electric motor, which allows the thruster apparatus to operate for long periods. In some embodiments, the motors are installed concentrically within their respective thruster ducts, with water flow through the ducts cooling the motors during operation. The system is controlled by a joystick located at the operator's station of the boat.

Abstract: The dual propeller surface drive propulsion system for boats is a combined propulsion and steering system for vessels with inboard engines comprising an enclosed thrust bearing assembly mounted to the transom of the vessel, a transom box mounted to the transom of the vessel that encompasses the thrust bearing assembly, an articulated outdrive pivotally connected to the transom box, a gearbox contained within the articulated outdrive, two counter rotating propeller shafts equipped with surface-piercing propellers and a steerable rudder system. Counter-rotating propellers reduce propeller-induced torque. By combining an articulated outdrive with a steerable rudder greater maneuverability of the vessel is achieved.
