A push fitting joint packaging arrangement allows the re-use and repair of push-to-connect fittings and valves without damage to the fitting or valve elements or the pipe, and without coining, gluing or threaded engagement of parts, while also requiring less force to connect and disconnect tubing elements. The apparatus includes a combined circuit for the capacitance sensor and TDR sensor that creates a separation between the return signal from the capacitance sensor and the TDR sensor. The adapter is coupled to the outer surface of the first conduit and has an annular first engagement surface positioned adjacent to the flange and an annular second engagement surface that is spherical and convex. The head portion includes an annular flange extending radially from the longitudinal axis. In this way, the disclosed techniques may provide accurate foreground object generation and low-complexity extraction of the foreground object from the video sequence. Each lug belt conveyor includes spaced apart transverse lugs along the length thereof against which the onserts are positioned.
