Abstract: A system and method for detecting unauthorized access to a CATV system at a site, including inserting a cable fraud detection unit into the site drop, periodically obtaining a first sample of a content signal from the site with the detection unit so as to determine if the site is accessing the content signal, storing the first sample in the detection unit, periodically obtaining a second sample of the content signal from the CATV system with the detection unit to serve as a reference for the first sample, and storing the second sample in the detection unit. The stored samples may be transmitted to the CATV system in response to a control signal or may be transmitted to a portable unit.

Abstract: A plumbing apparatus including a circular spirit level attached to a straight edge body adapted to carry a reference point vertically wherein the level is large enough to span a hole in the floor with marking guides on the periphery to fix lines that pass through a central axis of the level with a rod attached to the level extending through the hole to align with a reference point with a template spanning a second hole to define the reference point.
