Abstract: An exercise bike and an operation method thereof are provided. In a test mode, a processing unit adjusts a resistance of a pedaling activity to be a plurality of pedaling resistances and obtains a plurality of psychological values respectively corresponding to the pedaling resistances by inquiring the user about a rate of perceived exertion. The processing unit calculates the psychological values to obtain a plurality of exercise intensities respectively corresponding to the pedaling resistances and further obtain a correspondence relationship between the exercise intensities and the pedaling resistances. After the test mode ends, the processing unit determines a recommended pedaling resistance according to the correspondence relationship. In a sport mode, the recommended pedaling resistance is provided to the user for performing the pedaling activity.

Abstract: An exercise bike and an operation method thereof are provided. In a test mode, a processing unit adjusts a resistance of a pedaling activity to be a plurality of pedaling resistances and measures user's physiological characteristics. The processing unit accordingly obtains a plurality of physiological values respectively corresponding to the pedaling resistances. The processing unit calculates the physiological values to obtain a plurality of exercise intensities respectively corresponding to the pedaling resistances and further obtain a correspondence relationship between the exercise intensities and the pedaling resistances. After the test mode ends, the processing unit determines a recommended pedaling resistance according to the correspondence relationship. In a sport mode, the recommended pedaling resistance is provided to the user for performing the pedaling activity.

Abstract: A glass lens array module with alignment fixture and a manufacturing method thereof are revealed. A glass lens array is produced by multi-cavity glass molding and alignment members are arranged on a peripheral of non-optical area of the glass lens array. Optical axis of each of two adjacent glass lens arrays is aligned by corresponding alignment members and the glass lens arrays are assembled by glue. A spacer is disposed between the two adjacent glass lens arrays to form a preset interval if needed. Thus a glass lens array module is formed after curing of the glue. Thereby the alignment of the optical axis of the glass lens is achieved easily and optical precision is also attained. Moreover, the manufacturing processes are simplified and the cost is reduced.

Abstract: A stacked optical glass lens array, a stacked lens module and a manufacturing method thereof are disclosed. The stacked optical glass lens array includes at least two optical glass lens arrays whose optical axis are aligned and then stacked with each other by cement glue in glue grooves. A stacked optical glass lens element can be singularized by cutting along with the alignment notches of stacked optical glass lens array. The stacked lens module is formed by a single stacked optical glass lens element and related optical element mounted in a lens holder. Thereby the optical axis of the lenses of the stacked lens module are aligned precisely, the manufacturing processes are simplified and the production cost is reduced.
