Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
An underwater display unit for displaying breathing gas condition in underwater diving apparatus, comprising; an elongated rigid, fluid-tight housing having an elongated viewing window in a side wall thereof and an elongated chamber in said housing; a miniature indicator lamp carrying member, said lamp carrying member having a length corresponding to the length of said elongated chamber and received therein; means on said lamp carrying member for mounting a plurality of miniature color coded electrical indicator lamps spaced along the length of said chamber and along said side wall viewing window; connector means for electrically connecting said lamps to an external source of operating current, and for sealing said elongated chamber; and means for releasably securing said housing on the body of a user.
Claim 2
Dependent Claim
124 words
An underwater display unit for displaying breathing gas condition in underwater diving apparatus, comprising; an elongated rigid, fluid-tight housing having an elongated viewing window in a side wall thereof and an elongated chamber in said housing; a miniature indicator lamp carrying member, said lamp carrying member having a length corresponding to the length of said elongated chamber and received therein; means on said lamp carrying member for mounting a plurality of miniature color coded electrical indicator lamps spaced along the length of said chamber and along said side wall viewing window; connector means for electrically connecting said lamps to an external source of operating current, and for sealing said elongated chamber; and means for releasably securing said housing on the body of a user.
Claim 3
Dependent Claim
58 words
The invention defined in claim 1 wherein there are at least five of said miniature indicator lamps, in said row, the center lamp of which indicates a normal condition with the lamps to each side thereof indicating unsafe condition with the greatest degree of unsafety being indicated by lamps most remote from the lamp indicating said normal condition.
Claim 4
Dependent Claim
18 words
The invention defined in claim 1, including a light-transmissive non-conductive liquid filling the voids in said elongated housing.
Claim 5
Dependent Claim
45 words
The invention defined in claim 1, wherein said means for securing said unit on the body of a user comprises a wrist strap means securing said unit in position wherein said viewing window is in a plane parallel to the back of the user''s wrist.
Claim 6
Dependent Claim
159 words
An underwater display unit for displaying breathing gas conditions in underwater diving apparatus, comprising, an elongated housing having an elongated viewing window in a side wall thereof and an elongated chamber in said housing, a miniature indicator length carrying member, said length carrying member having a length corresponding to the length of said elongated chamber and received therein, said lamp carrying member having a plurality of spaced bores in a single row and extending normal to the longitudinal axis thereof and to said elongated side wall viewing window, each saId bore having a lamp base securing portion and a conically shaped lamp bulb receiving portion, said conically shaped bulb portion being adjacent said viewing window, a plurality of miniature electrical indicator lamps mounted in said bores, and connector means for electrically connecting said lamps to a source of operating current and for sealing said elongated chamber, and means for releasably securing said housing on the body of a user.
Claim 7
Dependent Claim
159 words
An underwater display unit for displaying breathing gas conditions in underwater diving apparatus, comprising, an elongated housing having an elongated viewing window in a side wall thereof and an elongated chamber in said housing, a miniature indicator length carrying member, said length carrying member having a length corresponding to the length of said elongated chamber and received therein, said lamp carrying member having a plurality of spaced bores in a single row and extending normal to the longitudinal axis thereof and to said elongated side wall viewing window, each saId bore having a lamp base securing portion and a conically shaped lamp bulb receiving portion, said conically shaped bulb portion being adjacent said viewing window, a plurality of miniature electrical indicator lamps mounted in said bores, and connector means for electrically connecting said lamps to a source of operating current and for sealing said elongated chamber, and means for releasably securing said housing on the body of a user.
Claim 8
Dependent Claim
39 words
The invention defined in claim 1 including at least one further lamp in said row and at an end thereof for providing an alarm indication in addition to and independent of any indication by the other of said lamps.
Claim 9
Dependent Claim
123 words
Apparatus for digitally displaying breathing gas condition in a breathing gas system comprising, an elongated housing having an elongated substantially transparent viewing window portion in a side wall thereof and an elongated chamber in said housing aligned with said viewing window, an indicator lamp carrying member having a length corresponding to the length of said elongated viewing window and received in said elongated chamber in said housing, a plurality of electric lamps carried by said lamp carrying member and spaced therealong and in contiguous relation with said elongated viewing window, connector means for electrically connecting said lamps to their source of operating current and for sealing said chamber, and means for selectively electrically energizing said lamps in accordance to digital signals applied thereto.
Claim 10
Dependent Claim
123 words
Apparatus for digitally displaying breathing gas condition in a breathing gas system comprising, an elongated housing having an elongated substantially transparent viewing window portion in a side wall thereof and an elongated chamber in said housing aligned with said viewing window, an indicator lamp carrying member having a length corresponding to the length of said elongated viewing window and received in said elongated chamber in said housing, a plurality of electric lamps carried by said lamp carrying member and spaced therealong and in contiguous relation with said elongated viewing window, connector means for electrically connecting said lamps to their source of operating current and for sealing said chamber, and means for selectively electrically energizing said lamps in accordance to digital signals applied thereto.
Claim 11
Independent Claim
121 words
A method of unambiguously displaying vital breathing gas system conditions to a diver underwater, wherein said system includes means for sensing the oxygen levels and supply therein and producing a control signal for each range of conditions, said method of display comprising, establishing a viewing line for said range of conditions, projecting green light from the center of said display for a normal condition, projecting red light from the spaces at the extreme opposite sides of the center of said display indicating dangerous conditions, and projecting amber light from the side spaces adjacent said center of said display and said extreme opposite sides of the center to indicate a degree of unsafe conditions intermediate said dangerous condition and said normal condition.
Claim 12
Independent Claim
