Abstract
Abstract This invention describes a method and apparatus for window foiling in a burglar alarm system. Precut geometric shaped metallic foil patterns are removably mounted on a support means. The patterns are mounted in its full shape. The window is initially foiled with straight line segments using conventional foil. The precut foil patterns are removed from the support and connected to the straight line segments in an overlapping relationship therewith. The overlapping portions can be perforated to provide good electrical contact therebetween.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
A METHOD FOR WINDOW FOILING A PRE-DETERMINED PATTERN IN A BURGLAR ALARM SYSTEM WITH THE PRE-DETERMINED PATTERN HAVING AT LEAST ONE CORNER, SAID METHOD COMPRISING THE STEPS OF: A. FOILING THE WINDOW WITH STRAIGHT LINE SEGMENTS OF ELECTRICALLY CONDUCTIVE FOIL TO THEREBY FORM PART OF THE PREDETERMINED PATTERN, B. APPLYING PRE-CUT, GEOMETRICALLY SHAPED METALLIC FOIL PATTERNS TO THE WINDOW IN AT LEAST PARTIALLY OVERLAPPING RELATIONSHIP WITH THE STRAAAIGHT LINE SEENTS TO THEREBY COMPLLETE THE PRE-DETERMINED PATTERN, AND C. ELECTRICALLY COUPLING THE PORTION OF THE STRAIGHT LINE SEGMENTS AND THE PRE-CUT PATTERNS THAT ARE OVERLAPPED TO THAT THE COMPLETE, PREDETERMINED PATTERN MAY BE CONNECTED TO THE BURGLAR ALARM SYSTEM.
Claim 2
Independent Claim
108 words
A METHOD FOR WINDOW FOILING A PRE-DETERMINED PATTERN IN A BURGLAR ALARM SYSTEM WITH THE PRE-DETERMINED PATTERN HAVING AT LEAST ONE CORNER, SAID METHOD COMPRISING THE STEPS OF: A. FOILING THE WINDOW WITH STRAIGHT LINE SEGMENTS OF ELECTRICALLY CONDUCTIVE FOIL TO THEREBY FORM PART OF THE PREDETERMINED PATTERN, B. APPLYING PRE-CUT, GEOMETRICALLY SHAPED METALLIC FOIL PATTERNS TO THE WINDOW IN AT LEAST PARTIALLY OVERLAPPING RELATIONSHIP WITH THE STRAAAIGHT LINE SEENTS TO THEREBY COMPLLETE THE PRE-DETERMINED PATTERN, AND C. ELECTRICALLY COUPLING THE PORTION OF THE STRAIGHT LINE SEGMENTS AND THE PRE-CUT PATTERNS THAT ARE OVERLAPPED TO THAT THE COMPLETE, PREDETERMINED PATTERN MAY BE CONNECTED TO THE BURGLAR ALARM SYSTEM.
Claim 3
Dependent Claim
47 words
The method according to claim 1 wherein the pre-cut patterns have an adhesive backing and are positioned removably on a backing strip and wherein said applying step comprises removing said pre-cut pattern from the backing strip and adhering them to the window and to the line segments.
Claim 4
Dependent Claim
26 words
The method according to claim 1 wherein said applying step comprises placing the pre-cut patterns at corner locations in the pre-determined pattern of the line segments.
Claim 5
Dependent Claim
26 words
The method according to claim 1 wherein said applying step comprises placing selected ones of the pre-cut patterns at least partially contiguously with the line segments.
Claim 6
Dependent Claim
34 words
The method according to claim 1 wherein said electrically coupling step comprises perforating the overlapped portions of the line segments and pre-cut pattern whereby the said overlapped portions are interlocked to provide electrical coupling.
