Abstract
Abstract A membrane panel including at least one electrical component. The panel includes a rigid support member having substantially planar top and bottom surfaces. At least one void region, or hole, extends from the bottom surface of that support member. A flexible top member including at least one flexible layer, overlies the support member. A flexible bottom member including at least one flexible layer underlies the support member. The bottom member has its upper surface affixed to the bottom surface of the support member. Further, the bottom member includes an integral flexible tail. The bottom member includes at least one electrical component affixed to its upper surface with that component underlying and extending into an associated one of the void regions of the support member. An electrically conductive pattern is affixed to the upper surface of the bottom member and that pattern is electrically coupled to the component to permit its operation in an electrical network.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
227 words
A membrane panel comprising: A. a rigid support member having substantially planar top and bottom surfaces, and including at least one void region extending from said bottom surface, B. A flexible top member including at least one flexible layer overlaying said support member, and C. a flexible bottom member including a flexible layer underlying said support member and said bottom member having its upper surface affixed to the bottom surface of said support member, and said bottom member including an integral flexible tail extending therefrom, wherein said bottom member further includes at least one electrical component affixed to said upper surface, said component underlying and extending into an associated one of said void regions, and wherein said bottom member further includes an electrically conductive pattern affixed to said upper surface and means for electrically coupling said pattern to said components and further comprising: a rigid spacer member having its top surface affixed to the underside of said top member, said spacer member including a void region extending from one edge thereof and underlying said top member, a base member affixed to the lower surface of said spacer member and underlying the void region defined by said spacer member, wherein said void region defined by said spacer member has a shape adapted to permit said support member and bottom members to be selectively inserted therein and withdrawn therefrom.
Claim 2
Dependent Claim
227 words
A membrane panel comprising: A. a rigid support member having substantially planar top and bottom surfaces, and including at least one void region extending from said bottom surface, B. A flexible top member including at least one flexible layer overlaying said support member, and C. a flexible bottom member including a flexible layer underlying said support member and said bottom member having its upper surface affixed to the bottom surface of said support member, and said bottom member including an integral flexible tail extending therefrom, wherein said bottom member further includes at least one electrical component affixed to said upper surface, said component underlying and extending into an associated one of said void regions, and wherein said bottom member further includes an electrically conductive pattern affixed to said upper surface and means for electrically coupling said pattern to said components and further comprising: a rigid spacer member having its top surface affixed to the underside of said top member, said spacer member including a void region extending from one edge thereof and underlying said top member, a base member affixed to the lower surface of said spacer member and underlying the void region defined by said spacer member, wherein said void region defined by said spacer member has a shape adapted to permit said support member and bottom members to be selectively inserted therein and withdrawn therefrom.
Claim 3
Dependent Claim
40 words
A membrane panel according to claim 1 wherein at least one of said components is a light emitting diode (LED) and wherein the layers of said top member and said support member include a light transmissive region overlying said LED.
Claim 4
Dependent Claim
43 words
A membrane panel according to claim 2 wherein said bottom member includes a plurality of flexible layers, wherein at least two or said layers include conductive patterns affixed to their surfaces, and further includes means for electrically coupling said pattern to said component.
Claim 5
Dependent Claim
35 words
A membrane panel according to claim 2 wherein the light transmissive regions of said top and support members are aligned when said support member is fully inserted into the void region of said spacer member.
Claim 6
Dependent Claim
95 words
A membrane panel according to claim 1 wherein said top member includes at least upper, middle and lower flexible layers successively stacked on said top surface of said support member, wherein said at least one of said upper and lower layers includes an integral flexible tail extending therefrom, wherein said upper and lower layers include conductive patterns on their surfaces adjacent to said middle layer, said patterns including at least one pair of overlapping portions, and wherein said middle layer includes a void region between the overlapping portions of at least one of said pairs.
Claim 7
Dependent Claim
43 words
A membrane panel according to claim 1 wherein said bottom member includes a plurality of flexible layers, wherein at least two or said layers include conductive patterns affixed to their surfaces, and further includes means for electrically coupling said pattern to said component.
