Abstract: An inclinometer for measuring a change in the inclination of a structure from a given initial position. The inclinometer comprises a frame, a pendulum and at least three distance-measuring device. The frame is rigidly connected to the structure such that the inclination of the frame has the same changes in inclination as the structure. The pendulum is freely suspended from the frame and comprises a first end attached to the frame and a freely moving opposite end. The distance-measuring devices at the frame have respective coplanar measuring axes converging at a single point. Each measuring device measures a change in the distance separating same from the pendulum.

Abstract: A fluid collection assembly including a container having an interior chamber for collecting fluid, and a quick connect device coupled to the top of the container to couple to a mated connection device on a drainage tube. The quick connect device and the mated connection device may be in an open configuration to permit fluid flow when engaged and in a closed configuration to prevent fluid flow when disengaged. An adjustable hanger may be attached to the container, including an adjustable member that vertically repositions the container.
