A light emitting diode lighting device and system that can be used for illuminating the interior and / or exterior of vehicles, aircraft, watercraft, signage or buildings is provided. It includes a voltage feedback constant current power supply circuitry and high power LEDs. The printed circuit assemblies are firmly mounted onto a continuous or semi-continuous mounting channel case that also works as a heat sink. By this means, it not only increases the reliability of the LED lighting tube but also it provides sufficient heat dissipation capability for the heat generated by the LEDs. Since the operating temperature of the LEDs is controlled and stays in cool condition, it dramatically increases the LED's lifetime and efficiency. The end caps of this LED lighting device are fully compatible with existing conventional fluorescent light fixtures and can directly replace those fluorescent lighting tubes in vehicles, mass-transit, watercrafts, aircrafts, signage or buildings with minimal modifications.

A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The transmission provides a simple manual shifting method for the user. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The present invention includes a continuously variable transmission that may be employed in connection with any type of machine that is in need of a transmission. For example, the transmission may be used in (i) a motorized vehicle such as an automobile, motorcycle, or watercraft, (ii) a non-motorized vehicle such as a bicycle, tricycle, scooter, exercise equipment or (iii) industrial equipment, such as a drill press, power generating equipment, or textile mill.

The present invention relates to a moment-resistant structure, sustainer, and method of construction for deformably resisting episodic loads, particularly those of high intensity. The episodic loads may be due to earthquake, impact, or other intense episodic sources. The structure and sustainer may be in buildings, bridges, or other civil works, land vehicles, watercraft, aircraft, spacecraft, machinery, or other structural systems or apparati. Deformation capacity is enhanced by the use of multiple dissipative zones. Dissipative zones that function in a manner similar to plastic hinges are determined by one or more voids that are located in the web of a sustainer. The one or more voids are of a size, shape, and configuration to assure that the dissipative zones deform inelastically when a critical stress, i.e., a maximum allowable demand, is reached, thereby developing the action of a structural fuse, preventing the occurrence of stress and strain demands sufficient to cause fracture of the connection welds or adjacent heat-affected zones, i.e., preventing the stress and strain demands from exceeding the strength capacity of the connection welds or adjacent heat-affected zones. The sustainers may be removably connected to the remainder of the structure, facilitating their replacement after inelastic deformation. The structure, sustainer, and method of construction may be utilized in new construction and in the rehabilitation of existing construction. Mechanical equipment and utilities may pass through the voids.

The present invention represents a procedure for compensating the heave movement of offshore cranes. The dynamic model of the compensation actuator (hydraulically operated winch) and the load hanging on a rope are derived. Based on this model, a path-tracking control unit is developed. To compensate the movement of the ship / watercraft caused by waves, the heave movement is defined as a time-varying disturbance and is analyzed with respect to uncoupling conditions. With a model expansion, these conditions are satisfied, and an inversion-based uncoupling control law is formulated. To stabilize the system, an observer is used for reconstructing the unknown state by means of a force measurement. Furthermore, the compensation efficiency can be improved by predicting the heave movement. There is proposed a prediction method in which no ship / watercraft models or properties are required. The simulation and measurement results validate the heave compensation method.

An automatic timing measurement system that provides a measure of time of passage of a watercraft through a prescribed course. Algorithms based on inertial or other estimates augmented by GPS speed / position measurements are used to track position of a watercraft. Said position estimates are used to allow the locations of prescribed courses to be mapped and memorized. Algorithms are then used to allow the apparatus to automatically detect passage of a watercraft through mapped courses for the purpose of measuring and reporting time of passage of said watercraft past key points in said course, and for modifying the behavior of the speed control portion of the apparatus if necessary at certain points in the mapped course. A measure of accuracy of driver steering can be provided along with the ability to automatically steer the watercraft through the course if “steer-by-wire” mechanism is available. GPS speed control is augmented with a secondary velocity measurement device that measures speed over water resulting in an optional user selectable real-time compensation for water current. Furthermore, GPS is used as the key input to produce boat speed-based pull-up profiles.

A surfboard-based powered water craft is propelled by gas or electric power plant. A water jet pump supplies water under pressure, which is exhausted through a steering nozzle.
