  • Flexible roof control system
    Patent number: 4936060
    Abstract: A system for controlling a flexible roof assembly of the type used to cover large structures determines the actual variable height of one or more sections of the roof assembly with respect to a fixed reference point and regulates the apparatus for elevating the roof assembly to accurately control the position of the roof assembly. The system includes a signal generator for generating a signal corresponding to the actual height to indicate a change in height of the roof assembly. The system may also include an apparatus for detecting the presence of either ice or snow in an area of an outer surface of the roof assembly.
