An acceleration control system is provided which allows the operator of a marine vessel to select an acceleration profile to control the engine speed of a marine vessel from an initial starting speed to a final desired speed. When used in conjunction with tow sports, such as wake boarding and water skiing, the use of acceleration profile provides consistent performance during the period of time when a water skier is accelerated from a stationary position to a full speed condition.

A system is provided which stores data relating to the operation of a marine vessel during a water skier launch procedure. The data can include a plurality of throttle handle positions that are stored at a frequency which is suitable for reproducing the movement profile of the handle during a launch procedure. The water skier launch profile is then stored so that it can be recalled and reactivated to repeat the acceleration profile of the boat.

A waterslide attraction capable of incorporating user skill or agility. The waterslide attraction utilizes a slide for supporting a rider, either with a ride vehicle or without. The ride vehicle may be a mat with handles that allows the rider thereon to manipulate its position or other elements while on the slide. Upon manipulating an element, a signal may be transmitted. Sensors located along the slide are configured to interact with tags having corresponding identification information, such tags either worn by the rider in accessories or embedded or coupled with the ride vehicle. When a tag is within a predetermined distance or vicinity of a sensor, one or more aspects of the waterslide attraction may be modified, such as by turning on jets of fluid or assigning score points associated with the identification information. A screen or mobile application displays various characteristics corresponding to travel performance down the slide.

A tire for vehicles offering low rolling resistance wherein the ground-contact surface area is variable as a portion of the tread part can be retracted and/or extended using pneumatic, mechanical or hydraulic force to withdraw from, or come into contact with the road surface before, during or after operation permitting more efficient operation wherein the material used within the tread part that retains contact with the road may generally have a smaller internal friction loss than the material used in conventional tires and the rolling resistance is thereby reduced when the retractable portion of the tread is selectively withdrawn from contact with the road surface furthermore achieving a smaller ground-contact patch footprint. The achieved object of a tire with a lower rolling resistance yields improved fuel consumption efficiency. Improvements in exterior and interior noise levels and a reduced tendency to exhibit hydroplaning action are also attained with a variable groove volume to tread surface-contact ratio. Within one embodiment of the present invention, an automated microcomputer-based tire control system is disclosed useable to command the motion of the moveable tread portion of the said tire in response to various operational scenarios.

The invention discloses a bionics-based non-skid tire pattern groove. The non-skid tire pattern groove is characterized in that a bionic non-smooth surface structure has effects of stickness reducing and resistance diminishing and can keep the shape and the arrangement of patterns on a tire tread constant, so that the inner wall of the tread pattern groove is provided with the non-smooth surface structure so as to reduce the resistance of rainwater which is discharged from the pattern groove, the water discharge of the tire pattern groove increases, and the water skiing speed of a tire is improved while tire noises do not increase. The pattern groove can improve the security of driving on rainy day and alleviate the contradiction between the water skiing and noises of the tire to a certain extent.

The invention discloses a water surface/underwater dual-mode vehicle comprising a vehicle body, a water jet propulsion system is arranged at the tail in the vehicle body, the tail of the vehicle bodyis connected with two vertical fin rudders opposite in position in the vertical direction, the tail of the vehicle body is connected with two horizontal fin rudders opposite in position in the horizontal direction, control mechanisms are arranged in the vertical fin rudders and the horizontal fin rudders, and the front portion of the vehicle body is further connected with a hydrofoil structure. Rapid distribution can be realized, and the throwing capacity facing a severe environment is enhanced. The water skiing sailing resistance of the vehicle is obviously smaller than that of underwater sailing, the combat radius of the vehicle can be increased, and the combat effectiveness is enhanced. The hydrofoil structure directly surrounds the vehicle body through the fragment-free explosive bolts, when the tail end of the vehicle attacks, the hydrofoil structure is separated and discarded through the control bolts to achieve underwater high-speed navigation, underwater defense blind areas ofenemies are fully utilized, and effective killing of surface ships of the enemies is achieved. When the vehicle slides on the water surface, the two ends of the main hydrofoil warp upwards, and good stability is achieved.

An adult flotation device is provided that as a life "vest" to prevent drowning. Attached to the upper area of a user's arms in the same location as "swimming wings", in their normal state, the device is not inflated and as such, it is extremely low-profile. Due to its low profile and lack of bulkiness, the invention is not cumbersome and allows the user to perform tasks such as fishing, rowing, water skiing and the like without hindrances. If the user should accidentally fall into the water and/or is unable to swim, the invention will transform into a flotation device by simply pulling on an inflation cord. With the invention inflated, the invention will lift the user to the surface.

A wireless water ski handle system used with a personal water ski towing watercraft that includes a handle component that selectively attaches to a standard water ski handle and contains a manual control module and a wireless transmitter. The control module includes directional control buttons, power ON and OFF buttons, and power Up and Down buttons. Located in the watercraft is a wireless receiver that communicates with the transmitter. Coupled to the receiver is a self-correcting propulsion and steering system that senses undesirable changes to the watercraft's motion caused by the water-skier when pulled by the watercraft. When a difference is detected, a command module located in the watercraft automatically controls the watercraft's propulsion and steering systems so the watercraft follows the desired path and velocity. The system also includes an auto-back tracking feature that automatically reduces power to the last known marked geographic point the skier was upright.
