Abstract: A platform through-beam sensor device includes a transmitter module and a receiver module. A light emitted by a light-emitting element of the transmitter module is shaped into a light pattern range by a transmitter mask. A range of the light received by a light-receiving element of the receiver module is changed to a receiving range by a receiver mask. When the present invention is used, the transmitter module and the receiver module are respectively installed on two ends of a mechanical apparatus that move relative to each other. After determining a safety range of the relative movement of the two ends, a state that the light-receiving element falls into the light pattern range and the light-emitting element falls into the receiving range is set to be within the safety range. Upon exceeding the safety range, a flying platform is controlled to stop, thereby improving the safety of the flying platform.

The first cross arm assembly includes a first arm and a second arm that are cross-connected to each other; a second cross arm assembly disposed on a second side between the base and the movable platform relative to the first side. The second cross arm assembly includes a third arm and a fourth arm forming an X-shaped connection; an actuator connected obliquely to an upper part of the first arm and the base or the lower part of the third arm to drive the movable platform to move along a first direction or its opposite direction; and a rod is horizontally connected with the upper part of the first arm and an upper part of the third arm. The base, the movable platform, the first arm and the third arm form a substantially parallelogram when the actuator is actuating.

Abstract: A fulldome display framework with a movable assembly adapted to dispose a plurality of display screens or projection screens to constitute a fulldome display includes a fixed frame engaged with a base surface and a movable frame disposed on the base surface and being movable relative to the fixed frame between an assembling position and a disassembling position along a predetermined route. The fulldome display is constituted when the movable frame is located at the assembling position to match with the fixed frame. In this way, after an LED fulldome display structure is installed on the present invention for example, the movable frame could be pulled out relative to the fixed frame along the predetermined route when a circuit board of a part of the fulldome display requires to be repaired, providing a certain working area for a repair worker to carry out repair and maintenance.

Abstract: A spherical screen module unit includes a sector base including a sector carrier having an inner and outer arc edges; arc length of the outer arc edge is greater than that of the inner arc edge. An inner ramp frame is on the sector carrier and closer to the inner arc edge; an outer ramp frame is on the sector carrier and closer to the outer arc edge. When the spherical screen module unit is on a spherical screen assembling surface, minimum distance between the inner ramp frame upper surface and the spherical screen assembling surface is first height; maximum distance between the outer ramp frame upper surface and the spherical screen assembling surface is second height which is greater than the first height. A spherical screen structure including spherical screen module unit facilitates the module unit disassembly for repair, maintenance, or angle adjustment, and increases applicability in different environments.

Abstract: A curved-surface displaying module is adapted to be disposed on a curved-surface support and includes a display panel and at least one restricting device. The curved-surface support has an engaging surface and a reverse surface which face opposite directions. The display panel has a displaying surface and a reverse surface which face opposite directions. The reverse surface of the display panel is adapted to be connected to the engaging surface. The restricting device is disposed on the reverse surface of the display panel. The restricting device includes a restricting member. The restricting member has a connecting portion and a restricting portion. An end of the connecting portion is pivotally connected to the reverse surface of the display panel, and another end of the connecting portion is connected to the restricting portion. The restricting portion of the restricting member is controllable to pivot to the reverse surface of the curved-surface support.

Abstract: A mapping method for a fulldome display, including convert an original image into a deformed image corresponding to the fulldome display; divides the deformed image into at least one first image, at least one second image, and at least one third image; incorporate the third image with the second image to form at least one intermediate image; display image pixels of the first image on display pixels of at least one first displaying module of the fulldome display based on a first mapping relation; display image pixels of the intermediate image on display pixels of at least one second displaying module of the fulldome display based on a second mapping relation. In this way, the increased image pixels of the third image could be transmitted and be displayed.

Abstract: A kinesthetic device that simulates flight includes a base unit and a swing unit. The base unit includes a base seat; whereas, the swing unit includes a swing seat, two swing support structures pivoted between the base seat and the swing seat, and a swing actuator used to control the swing positions of the two swing support structures. The two swing support structures are equal in length and parallel to each other. A fixed baseline is formed between two junction points between the two swing support structures and the base seat, a swing baseline is formed between two junction points between the two swing support structures and the swing seat, and the fixed baseline and the swing baseline are equal in length. The two swing support structures, the fixed baseline and the swing baseline form a parallelogram, allowing the swing support structures to swing stably the base seat.

Abstract: A dynamic simulator includes a carrying platform, a movable platform, a load carrying seat, a first actuator pivotally coupled to carrying platform, and a second actuator pivotally coupled to movable platform, and an included angle is formed between the first actuator and the carrying platform, and an included angle is formed between the second actuator and the load carrying seat, and an included angle is formed between the second actuator and the first actuator, so as to simplify the dynamic simulator.

Abstract: A lateral dynamic simulation device includes a positioning platform (1), a motor mechanism (2) and a carriage (3). The positioning platform (1) has an upright positioned arm (10). The motor mechanism (2) has multiple degrees of freedom and comprises a base (20), a platform (21) and a plurality of stretchable bars (22) to join the base (20) and the platform (21) by the universal joints (220). The carriage (3) has a space (30) at the frontal portion for carrying passengers and a back portion (31) at the rear portion. The base (20) of the motor mechanism (2) is fixed to the arm (10) of the positioning platform (1) and the platform (21) of the motor mechanism (2) is fixed to the back portion (31) of the carriage (3).

Abstract: A motion simulator has a motive device suspended in midair and having a base, a moving panel, twelve universal joints mounted on the base and the moving panel and six actuators connected to the universal joints and being retractable. A seat assembly is hung on the moving panel. Therefore, as the actuators retract, the seat assembly is moved in six degrees of freedom such as heave, sway, surge, pitch, roll and yaw. Audiences sitting on the seat assembly are hung with their feet hanging in the air and therefore feel excited and experience vivid virtual reality. Moreover, the actuators bear axial force such as drag force and thrust force and are endurable and safety.
