Let's do a back-of-the-envelope calculation. Assume a 7" riser height. 94/7 = 13.4 risers but since we can't have a fraction of a step, we either increase to 14 risers (giving a step height under 7") or 13 risers (giving a step height just over 7". Let's use 13. 94" ...
Step 4: Attach slide supports We cut triangular supports to the depth and height of our stairs and attached in four places on each side by screws from the top andL bracketsunderneath. We chose to place the triangle supports at the top and bottom, then as equally spaced between as possible...
156" / 7" step height = 22.28 steps, so we will round to 28 step risers or steps 156" / 22 = 7.09" so we can make our individual step height 7.1" Now we know the stair step height Now 22 steps x 11" step tread depth = 242" of horizontal run 242" / 12 = 20.16 feet So ...

Since the riser (step height) and tread (step depth) dimensions of the stairs are known, we add an additional correction to the position estimate. In particular, we designed a single-state Kalman filter that makes corrections to the IMU-derived vertical foot position (𝒙=[𝑝𝑧])(x=[...
The stair calculator calculates stair rise and run, stair angle, stringer length, step height, tread depth, and the number of steps required for a given run of stairs. For convenience and flexibility, this stair stringer calculator comes in two forms: automatic and manual. Click on the [?]...
A stair-step, expandable file folder is disclosed, in which each pocket in the folder has the same depth, rather than the back pockets being deeper than the front pockets. The folder includes a series of dividers that form the front and back sides of the pockets of the folder. The top ...
