  • Patent number: 7462136
    Abstract: An elliptic motion exercise machine includes a frame, on which a reciprocating motion mechanism, a circular motion mechanism and two linking members are provided. Two parallelogram linkage mechanisms are movably mounted on the frame and connected to the linking members. Two foot panels are fixed on the parallelogram linkage mechanisms respectively. The parallelogram linkage mechanisms keep the foot panels in fixed slops in the entire motion, such that when an user stands feet on the foot panels and exerts the foot panels, toes of user's feet moves in a speed that is substantially identical to that of use's heels.

  • Publication number: 20080103021
    Abstract: A guiding structure of a treadmill for guiding electrostatic charges of a human body is disposed between a treadmill base and the human body to connect the human body to the treadmill base continuously. Thus, potentials between the human body and the treadmill base may be kept in a substantially balanced state, and it is possible to prevent a high-potential one of the human body and the treadmill base to instantaneously discharge the electrostatic charges to a low-potential one. Thus, the user can use the treadmill in a relieved manner.

  • Patent number: 7175182
    Abstract: An automatic score dartboard assembly has a base, a dartboard, a support, at least one imaging element and a main control circuit. The dartboard and the support are attached to the base, and the at least one imaging element is mounted on the support to capture a direct viewing image of the dartboard periodically. The images are output to the main control circuit to determine the score of a dart when the dart sticks in the dartboard. The main control circuit is composed of an image processor and a memory device. The image processor uses an image comparison method to determine the score of the dart. Therefore, the present invention uses as few as one imaging element to determine the score and increases accuracy of determining score.
