The assembly of the mother lens and the daughter lens includes: aligning square embedded lens bodies of the daughter lens with square holes of the mother lens, respectively, for allowing the first parabola-shaped holes on the mother lens and the second parabola-shaped holes on the daughter lens to form an orthogonal structure; and inserting and pressing the square embedded lens bodies into the corresponding square holes, respectively. The method of the invention has advantages of high-precision for manufacturing and calibration of optical axis, and meanwhile the compound refractive lens manufactured based the method has high X-rays focusing efficiency.

Abstract: An exemplary electronic device is connected with an earphone. The earphone includes a first storage unit storing information as to functions of the earphone. The electronic device includes a second storage unit storing a function information table recording information as to user-controllable functions of the electronic device, function units corresponding to the user-controllable functions, an identifying module, and a control module. The identifying module retrieves the information as to functions stored in the first storage unit, and determines whether one or more of the controllable functions of the electronic device are controllable by the earphone. The control module activates all of the function units corresponding to the controllable functions of the electronic device which are controllable by the earphone, and controls one or more of the activated function units according to one or more control signals transmitted from the earphone to the electronic device. A related method is also provided.

Abstract: An electronic device includes an acceleration sensor and a rotation sensor, both being independently powered, in providing a method of unlocking when locked. An acceleration of the electronic device is detected using the acceleration sensor and a rotation angle of the electronic device is then detected using the rotation sensor. The electronic device is unlocked only if the acceleration of the electronic device exceeds the predetermined value and the electronic device is additionally rotated a predetermined angle within a predetermined time.

Abstract: An electronic device capable of detecting ultraviolent radiation and a method thereof are provided. The device includes a camera, a voltage-sensitive optical medium, a control switch, and a processor. When the electronic device enters an ultraviolent radiation detecting mode, the camera captures a first image. The processor controls the control switch to create an electrical potential across the optical medium and cause it to become darker after the camera captures the first image. The camera captures a second image after the control switch has allowed an electrical potential for a first preset time interval. The processor acquires reads the respective brightness of the first image and the second image, determines any difference, and determines and outputs the level of intensity of the ultraviolent radiation intensity by reference to a table of differences.

Abstract: A music playing system is provided. The system includes a control module, an acquiring module, and a playing module. The control module controls the electronic device to enter a predetermined playing mode in response to a first input operation received by the input unit. The acquiring module acquires the name of each song and the start position and end position of the predetermined segment associated with the acquired name of the song from the table when in the predetermined playing mode. The playing module plays the predetermined segment of each song based on the start position and end position of predetermined segment associated with the acquired name of the song. An electronic device and a music playing method are also provided.
