Abstract: A lifting and folding mechanism for treadmill includes a base, a platform, a lifting mechanism, and a linkage mechanism. An armrest rack and a control panel are assembled at the base. A front end of the platform is pivotally assembled with the armrest rack. The lifting mechanism includes a supporting rack and a driving device. One end of the supporting rack is pivotally assembled with the platform, and the driving device is connected between the supporting rack and the platform for driving the supporting rack abutting against the ground, so that the platform is lifted and the slope of the platform is changed. The linkage mechanism is connected to the base and the platform. The linkage mechanism is in a connection state or a disconnection state. In the connection state, the base is connected with the platform, and the base is lifted upward with the lifting of the platform.

Abstract: An exercise bike includes a frame, a driving member, two sun gears, two swing arms, two planet gears, and two cranks. The driving member is assembled to the frame and has a shaft extending from two sides of the frame. The two sun gears, the two swing arms, the two planet gears, and the two cranks are respectively assembled to the two sides of the frame. For each set, the crank drives the planet gear to rotate so as to drive the swing arm to rotate the shaft, and the planet gear is rotated around the sun gear. Accordingly, a pedal connected to each of the cranks moves around the axis of the corresponding planet gear.

Abstract: This specification discloses a control panel structure of fitness equipment that includes a control board for controlling settings and display of the fitness equipment, a panel disposed above the control board, and a plurality of light-guiding elements disposed on the panel. The light-guiding elements are parallel to the panel. Each of the light-guiding elements has a hollow part with an opening on its one end. A light-emitting source is disposed inside the light-guiding element via the opening and electrically connected with the control board.

Abstract: A circuit for eliminating abnormal sound includes a video/audio processor, a D/A converter, a front-stage mute circuit, a changing delay device, a front-stage amplifier, a back-stage amplifier, a back-stage mute circuit, and a micro control unit. The circuit is mounted in a display device connected to a DVD player. When DVD player plays the video/audio signal having HDMI standard, the display device will generate an abnormal sound (pop voice or declining voice) during performing an operation such as pause, stop or play. Therefore, this circuit uses the changing delay device, the micro control unit, and the mute circuit to filter out the noise for providing a better outputting quality.

Abstract: The present invention relates to a method applied on displays for recognizing video signal timing of analog input. The present invention employs the horizontal-synchronized-signal interrupt value to distinguish among its inputted video signal timing, allowing to recognize its pixel and correctly display its corresponding video signal timing even when the inputted signal timings share the same horizontal frequency, vertical frequency, and polarity. In case when the display is displaying incorrect video signal timing, the present invention also allows inputting a switch signal to adjust its display mode accordingly, enabling the display to show the correct resolution of the video signal timing under normal operation.

Abstract: A brightness adjusting circuit for a display device has a brightness adjusting button on the display. When the user presses the brightness adjusting button, the brightness adjusting circuit reads display parameters stored in the memory and adjusts the brightness of the display device according to the display parameters to satisfy different brightness requests from the user for different applications.

Abstract: One embodiment of the invention comprises a portable device support structure having a support section including a plurality of support legs, a clamping section connected to the support section, the clamping section having a first section and a second section, wherein at least the first section is movable. The portable device support structure also includes an adjusting member which adjusts the position of the first section with respect to the second section. The clamping section clamps the portable device when the portable device is placed between the first section and the second section and when the adjusting member is actuated to apply force on the portable device between the first section and the second section.
