摘要： A roller foot, which can be mounted on the bottom of an electrical apparatus, includes a housing, a wheel axle and a wheel. The housing has a top frame, a left frame and a right frame. A right axle hole and a left axle hole are mounted on the inner surface of the right frame and the left frame respectively. The wheel axle is pivotally configured in the left axle hole and the right axle hole. The vertical size of each of the left axle hole and the right axle hole is larger than the wheel axle such that the wheel axle can be moved relative to the center of the left axle hole and the right axle hole. The wheel has a wheel axle hole. The wheel axle is configured in the wheel axle hole.

摘要： A tool is needed for music instrument learners to get feedbacks on the correctness of their performances of a particular piece of music. The invention disclosed here is such a tool that can provide music instrument players instant feedback on note pitch and rhythms accuracy based on sheet music. This is accomplished through audio signal processing, sheet music image processing, and conversion of both analogue images and audio signals into standard digital music representation so a comparison can be done and hence a feedback can be presented to the player. An advanced feature will allow users to save the data to the cloud and retrieve later for comparison of progress. It also will allow user to participate an online competition with other players of the same piece of music.

摘要： An optical connector is disclosed. The optical connector includes a rear housing, an inner housing, an arm and an outer housing. The inner housing includes at least one retaining hole to house a ferrule. The rear housing moves linearly with respect to the inner housing and rotates with respect to the inner housing. The arm moves linearly together with the rear housing with respect to the inner housing. The outer housing is disposed on an outer periphery of the inner housing so as to cover a front portion of the inner housing. The outer housing rotates with respect to the inner housing by a rotation guiding mechanism cooperating with the arm. The outer housing includes a forward wall covering the distal end of the inner housing. An opening area of the forward wall can be aligned with the retaining hole or a fiber exposure face of the ferrule when the outer housing is rotated with respect to the inner housing from an initial position to a connected position.

摘要： A notebook computer has a base, a support structure and a screen display. The base has a recess structure mounted on the upper surface of the base. The bottom end of the support structure is pivotally configured in the recess structure. The upper end of the support structure is pivotally configured on the screen display. The screen display may be lifted by the rotation of the support structure relative to the base and/or the screen display. When the screen display of the notebook computer is closed, the support structure is hidden in the recess structure to reduce the size of the notebook computer.
