Orange conrod, green and upper yellow cranks create a parallelogram mechanism. R1: pitch radius of green gear R2: pitch radius of blue gear i = R1 / R2 = 40 / 19. This ratio is needed to meet requirement when green gate rotates α = 58 deg., blue gate rotates 90 deg. in relation with the gr

Latches and Flip-Flops 3 - The Gated D Latch
This is the third in a series of videos about latches and flip-flops. These bi-stable combinations of logic gates form the basis of computer memory, counters, shift registers, and more. In particular, this video covers the gated D latch, otherwise known as the data latch or simply the D

The gate panel includes a lower portion (in blue) that is folded when open thanks to a bevel gear drive. Thus, the panel does not collide with the uphill ground. Transmission ratio of the bevel gear drive is 2. For more uphill ground the height of the lower portion is larger. For larger o

Thanks to violet face cam the gate panel is raised when open, thus it does not collide with the uphill ground. This mechanism is suitable for case when the gate is not too wide and the ground is not too uphill (for easy raising the gate panel). STEP files: http://www.mediafire.com/file/vu
