Abstract: An upright bike includes a main frame including a front portion and a rear portion. A rail structure is connected to the rear portion of the main frame. An X-shaped frame is slidably mounted to the rail structure and pivotally connected to the front portion of the main frame. A slide end is formed on the X-shaped frame and slidably mounted onto the rail structure. A stepping structure is mounted on a lower section of the first trestle of the X-shaped frame. A seat is secured on a top of the first trestle of the X-shaped frame. A handlebar is transversally secured on the X-shaped frame. A restitute element has two opposite ends respectively secured on the first trestle and the second trestle of the X-shaped frame for providing restitution force to the X-shaped frame when the handlebar is upwardly pulled.

Abstract: Replacing display content in a window of a graphical user interface includes displaying a window in a graphical user interface, and displaying first display content in the window. A request initiated by a user to change a size of the window is received. Second display content is accessed based on the request. The second display content is different from the first display content. In response to the request, the window is resized and the second display content is substituted for the first display content in the resized window.

Abstract: The swaying fitness equipment structure includes a stand, which is equipped with two brackets located at the opposite side on its top. There is an effector, having two brackets located at its middle portion forming a pivot structure. A active drive mechanism is located on the top of the stand. A passive-driven mechanism is placed on the top of the stand and faces the active drive mechanism. A linked mechanism is connected between the active drive mechanism and the passive-driven mechanism. The effector mechanism is located at the eccentric axis on the other side of the passive-driven mechanism, causing the effector mechanism to sway.

Abstract: The stepper with improved structure has a base, two pedals and the resistance device. The front ends of these two pedals are pivoted respectively on the protruding prop at the front of the base, which becomes the movable ends for the two pedals that provides the twisting motion in up and down directions, and forms a force of resistance when stepping provided by the resistance device. The bottom of the protruding prop is mounted on the base pivotally, which puts the prop in a revolvable position; a triangular guide mounted on the base, and its two oblique planes sets correspondingly and relatively to the movable ends of the two pedals, and on the bottoms of the movable ends of the pedals are the sliding part that are mounted pivotally on the oblique planes of the triangular guides. When the pedals are stepped down, they generate the motion that twists left and right downward diagonally as well.
