ABSTRACT:
An alarm system for boat covers is shown which deters the removal or the slicing of said cover. A perimeter circuit embedded into the hem of the cover is used in conjunction with specially adapted snap receptacles for cover removal protection. When snapped, the specially adapted snap receptacles act as closed switches in the perimeter circuit, and when unsnapped they act as open switches in the perimeter circuit. The cover is protected from slicing by circuitry affixed thereto. In the preferred embodiment a conduction grid made of a high-resistance material is affixed to the cover. A microprocessor constantly monitors the resistance and trips the alarm when the resistance substantially changes. The microprocessor is also capable of detecting resistance changes in the perimeter circuit if high-resistance wire is used for that circuit. In an alternative embodiment, wire electrical circuits are affixed to the surface of the boat cover. The system may also be adapted for use on convertible automobile covers by simply removing the perimeter circuit.
