A system and a method are disclosed for adaptive probabilistic tracking of an object within a motion video. To prevent deformation of the neck, it receives a rigid reinforcing body provided with a groove that extends from a first end of the body and terminates at a distance from the opposite second end, so that the rigid body has a grooveless end region and a grooved end region. The top cap seals on a top surface contact ring of a wafer, and the bottom cap seals on a bottom surface contact ring of the wafer. Each latch is capable of storing one bit of data. A hanger can then be attached to the production tubing string to carry the weight of the shroud assembly, motor, and seal section. One or more equalization transistors ensure the latch remains in the metastable state until it is enabled.
