摘要： A brightness enhancement film (BEF) includes a light transmissive substrate having a first surface and a second surface, a plurality of lenses disposed on the first surface, and a reflective layer. Each of the lenses has a curved protruding surface facing away from the light transmissive substrate. The radius of curvature of the curved protruding surface in a first direction parallel to the first surface is R1, the radius in a second direction is R2, and R1≠R2. The reflective layer is disposed on the second surface and has a plurality of light pass openings respectively located on the optical axes of the lenses. The distance between the apex of the curved protruding surface and the corresponding light pass opening is L, the refractive index of the lenses is n, and the BEF satisfies L

摘要： A pitching practice apparatus includes a frame unit having a rectangular frame member, X-axis and Y-axis sensor units mounted on the frame member, a control unit connected to the sensor units and to a sound generating device, and a net body provided on the frame unit. The sensor units are operable so as to form sampling regions for sensing entry of a ball into the frame member. The control unit determines position of the ball entering into the frame member, and compares the ball position with preset parameters to determine whether the ball is a good ball or a foul ball. Ball information determined by the control unit is shown on a display device. The sound generating device is used to generate a sound output corresponding to status of the ball that was thrown into the frame member as determined by the control unit.
