The closed construction of the plummets is the basic measurement set (a few plummets mutually connected) and control set (a single plummet mounted on the whole length).
The control set (10) is a separate plummet, which allows to perform control of inclinations of the particular plummets of the basic set (9) according to the formula 1:
where: sum of inclinations of the particular plummets [DELTA][y.
After setting (mounting) the plummet in a rock block (Figures 3B and 3C) there is registered the position of the shining optic fibre core at the time t0, and then after a lapse of time -[t.
On the basis of the project assumption there is created the prototype of the optoelectronic plummet, which is presented in Figure 5.
In Figure 5 there is presented a view of the plummet mounted by the tribrach to the observation pillar.
To perform experimental works there are used two different measurement sets allowing for the inclination of the optoelectronic plummet at a given angle value.
By inserting the next plates under the base of the plummet the location of the optic fibre is inclined.
In Figures 7A and 7B there are presented the change of the optoelectronic plummet position with the use of the machine spirit level- the plummet inclination at the alfa angle.
They contacted people at DebRA, a national EB support group, and were put in contact with a woman named Stacey Plummet, an EB sufferer who runs a local support group in North Carolina.
In a news interview several months later, Stacey Plummet had this to say: "[Genia's] made the perfect extension of our family.
