Abstract: A laser match honing system and method are provided for processing one of a pair of mechanically matching components (1, 2) having matching portions (12, 22, 16, 26) that will be fitted with each other. A dimension of the matching portion (12, 16) of the first component (1) is measured and is then used for calculating the desired dimension of the corresponding matching portion (22, 26) of the second component (2). An actual dimension of the matching portion (22, 26) of the second component (2) is also measured. Then, the matching portion (22, 26) of the second component (2) is honed by laser beam in the condition that the actual dimension is not equal to the desired dimension.

Abstract: A stationary exercise bicycle includes a base, and right and left pedals mounted to the base. The pedals are configured to rotate in operation about an axis of rotation. A frame has a rear end pivotally mounted to the base, and a forward end spaced apart from the rear end. A saddle is coupled to the rear end of the frame, and a handlebar is coupled to the forward end of the frame. The stationary exercise bicycle includes an actuator coupling the frame to the base. The actuator is configured to pivot the frame relative to the base about the axis of rotation, which can enable the rider to maintain the same general position as the frame is pivoted between normal and inclined positions.
