The disclosure relates to a system for simulating a maritime environment. The system includes a data duplicator, where an input interface is configured to receive sensor data from a sensor of a maritime vessel, a processor is configured to duplicate the sensor data, a first output interface is configured to provide the sensor data, and a second output interface is configured to provide the duplicated sensor data. The system may also include a training environment simulator, where an input interface is configured to receive the duplicated sensor data, a processor is configured to simulate the maritime environment based on the duplicated senor data, and a display is configured to display a virtual representation of the maritime environment. The system may also include a data processing device, where an input interface is configured to receive the sensor data and a processor is configured to process the sensor data.

The present invention discloses a push-swing combined wave generator, comprising a wave-generating fixing bracket, a servo motor, a driving wheel, a connecting rod, a first hydraulic cylinder, a second hydraulic cylinder, a first hydraulic cylinder push rod, a second hydraulic cylinder push rod, and a wave-generating plate. The sliding pins arranged in the wave-generating plate slide in the axial direction, and are switchable to connect either the first hydraulic cylinder push rod or the second hydraulic cylinder push rod with the wave-generating plate, and thus to render the push-swing combined wave generator to operate in respective locked state or unlocked state. The present invention integrates pushing and swinging, is capable of implementing horizontal pushing and swinging wave generating modes respectively, generating various wave types, and meeting requirements of various forms of wave generating.

Methods and systems for simulating motion in a virtual reality system without external motors or similar machinery are described herein. A mechanical seat may be mounted to a base such that the seat is moveable in at least two dimensions (e.g., roll and pitch). A human occupant of the seat may use a control yoke fixed in relation to the base to cause the chair to move in a direction opposite of the force exerted on the control yoke. An extended reality (XR) motion controller may be mounted in a fixed relationship to the seat. Motion may then be simulated in an XR environment by depicting acceleration that would yield a similar experience on the user's vestibular senses as gravity exerts on the user's vestibular senses based on motion of the seat.

A method and apparatus for assessing performance of an operation for a vehicle. Real-time information is received by a computer system in the vehicle from at least one of a vehicle operator or a group of hardware systems in the vehicle during the operation for the vehicle. The performance of the vehicle operator in performing the operation is determined by from the real-time information. A graphical image of the feedback is displayed in a display system in the vehicle during the operation in which the graphical image provides guidance in operating the vehicle to perform the operation. The graphical image of the feedback comprises a graphical indicium of a corrective action for the correcting operation of the vehicle while carrying out the operation of the vehicle in which the graphical indicium enables improving performance of the operation of the vehicle by the vehicle operator.

A system may include a housing that may hold a body of water, an inflatable assembly disposed within the body of water, and a processor. The processor may receive an indication related to a speed of a flow of the body of water and send a signal to at least one valve coupled between the inflatable assembly and a fluid source in response to the indication. The signal may cause the at least one valve to fluidly couple the inflatable assembly to the fluid source to cause the inflatable assembly to expand to an inflated configuration.
