20140124658 | GATE CONTROLLER MECHANISM - A gate controller mechanism includes a housing, a shaft mounted to the housing, a shaft screw thread formed on the shaft, a first limit wheel having a first limit wheel notch and having a first limit wheel threading engaging with the shaft screw thread, a second limit wheel having a second limit wheel notch and having a second limit wheel threading engaging with the shaft screw thread, a rail edge mounted to the housing and engaging into the first limit wheel notch and engaging into the second limit wheel notch, a first switch actuated by the first limit wheel, and a second switch actuated by the second limit wheel. The first limit wheel notch and the second limit wheel notch slide along the rail edge when the shaft rotates. | 05-08-2014 |
20140175270 | DISPLAY MEASURING DEVICE - A display measuring device for measuring a display, includes a photosensitive unit, a first rotation plane mirror, a second rotation plane mirror, a first lens module, a second lens module, and an optic reflecting unit. The first lens module projects a first incident image from the display to the first rotation plane minor. The first rotation plane minor reflects the projected first incident image from the first lens module to the optic reflecting unit. The second lens module projects a second incident image from the display to the second rotation plane minor. The second rotation plane minor reflects the projected second incident image from the second lens module to the optic reflecting unit. The optic reflecting unit reflects the reflected first incident image to the photosensitive unit, and reflects the reflected second incident image to the photosensitive unit. | 06-26-2014 |
