Abstract
Abstract A system for disabling and protecting a particulate detector (10) as necessitated by many building, construction, and maintenance projects is disclosed. The particulate detector (10) is typically mounted on a ceiling or vertical wall surface (12), and a jacket (22) is secured to a body portion (16) of the particulate detector (10). The jacket (22) includes a non-opaque plastic container (24) with an opening (34) on one end and being substantially sealed elsewhere. A flag (26) attaches to the container (24) and hangs downward when the jacket (22) is installed on the particulate detector (10). Moreover, an opening control device (28) couples to the container (24) near the opening (34) thereof to control the size of the opening (34) so that the particulate detector (10) may be substantially inserted into the jacket (22) and so that the jacket (22) may be secured to the particulate detector (10).

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
115 words
A method of disabling an otherwise operational particulate detector, said method comprising the steps of: inserting said particulate detector into a flexible bag having an opening therein, said opening having an expanded state and a contracted state, said opening being sufficiently large in said expanded state for said particulate detector to pass through said opening, and said bag being constructed from a material which is substantially impervious to dust; and constricting said bag opening so that said opening exhibits said contracted state, said bag contacts said particulate detector, and said bag becomes sufficiently secured to said particulate detector so that the entire weight of said bag is supportable by said contact with said particulate detector.
Claim 2
Independent Claim
115 words
A method of disabling an otherwise operational particulate detector, said method comprising the steps of: inserting said particulate detector into a flexible bag having an opening therein, said opening having an expanded state and a contracted state, said opening being sufficiently large in said expanded state for said particulate detector to pass through said opening, and said bag being constructed from a material which is substantially impervious to dust; and constricting said bag opening so that said opening exhibits said contracted state, said bag contacts said particulate detector, and said bag becomes sufficiently secured to said particulate detector so that the entire weight of said bag is supportable by said contact with said particulate detector.
Claim 3
Dependent Claim
34 words
A method as claimed in claim 1 additionally comprising the step of forming said bag from a non-opaque material so that said particulate detector is observable from outside said bag after said constricting step.
Claim 4
Dependent Claim
34 words
A method as claimed in claim 2 additionally comprising the step of attaching a flag to said bag, said flag being attached so that it extends downward from said bag after said constricting step.
Claim 5
Dependent Claim
79 words
A method as claimed in claim 1 wherein said constricting step comprises the steps of: gathering portions of said bag together proximate said opening; and applying a tape having first and second adjacent adhesive portions, said first portion being affixed to said bag at a first location thereon proximate said opening and said second tape portion being affixed to said bag at a second location proximate said opening thereon, said second location not residing adjacent to said first location.
Claim 6
Dependent Claim
30 words
A method as claimed in claim 1 wherein said constricting step comprises the step of pulling a drawstring slidably coupled to said bag proximate to and substantially surrounding said opening.
Claim 7
Dependent Claim
43 words
A method as claimed in claim 1 additionally comprising the step of attaching a flag to said bag, said flag being attached so that it extends downward beneath said bag after said constricting step to draw attention to the presence of said jacket.
Claim 8
Independent Claim
139 words
A method for operating a particulate detector in a substantially disabled state, said particulate detector exhibiting an alarm state when said particulate detector detects a quantity of particulate matter which is in excess of a predetermined threshold, and said method comprising the steps of: partially inserting said particulate detector into a flexible container having an opening therein, said opening being sufficiently large for said particulate detector to pass through said opening, and said container being constructed from a material which is substantially impervious to said particulate matter; clamping a portion of said container proximate said opening to said particulate detector to attach said container to said particulate detector so that the entire weight of said container is supported by said clamping; and dangling a strip of material beneath said container to draw attention to the presence of said container.
Claim 9
Independent Claim
139 words
A method for operating a particulate detector in a substantially disabled state, said particulate detector exhibiting an alarm state when said particulate detector detects a quantity of particulate matter which is in excess of a predetermined threshold, and said method comprising the steps of: partially inserting said particulate detector into a flexible container having an opening therein, said opening being sufficiently large for said particulate detector to pass through said opening, and said container being constructed from a material which is substantially impervious to said particulate matter; clamping a portion of said container proximate said opening to said particulate detector to attach said container to said particulate detector so that the entire weight of said container is supported by said clamping; and dangling a strip of material beneath said container to draw attention to the presence of said container.
Claim 10
Dependent Claim
30 words
A method as claimed in claim 7 additionally comprising the step of observing said particulate detector through said container to determine whether said particulate detector is in said alarm state.
Claim 11
Dependent Claim
26 words
A method as claimed in claim 7 wherein said dangling step extends said strip of material a distance of at least 12 inches beneath said container.
Claim 12
Dependent Claim
35 words
A method as claimed in claim 7 wherein said dangling step comprises the step of displaying a non-white color from said strip of material to enhance the attention drawing ability of said strip of material.
Claim 13
Dependent Claim
49 words
A method as claimed in claim 7 wherein particulate detector mounts on a generally vertical surface, and said dangling step comprises the step of spacing said strip of material away from said surface to reduce interference from said strip of material with activities conducted in connection with said surface.
