Abstract
Abstract A safety-glass windshield has at least one antenna wire imbedded in its plastic core layer. One of the glass lamina is formed with a tapered throughgoing hole having a narrow mouth on the inside surface of the windshield. The antenna wire terminates at the recess formed by this hole and has its end there imbedded in a mass of conductive lacquer. An active-circuit capsule shaped as short cylinder is connected via leads to the car radio and has a plurality of spring feet which fit snugly into the recess while the face of the capsule lies against the windshield over this recess. The feet diverge away from the capsule and have bent-over ends so that the capsule can be plugged into the recess, at least one of the feet forming a connection between the conductive lacqer mass and electronic components within the capsule.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
92 words
In a motor veHicle having a radio the improvement comprising the combination of: a window glass formed with a recess; an antenna element bonded to said window glass and having an end at said recess; an active-circuit capsule having active electronic circuit components connectable to said radio and having at least one formation resiliently engageable and form-fitting in said recess with said capsule lying on said window glass over said recess; and means between said components of said capsule and said end of said antenna in said recess for connecting same together.
Claim 2
Dependent Claim
92 words
In a motor veHicle having a radio the improvement comprising the combination of: a window glass formed with a recess; an antenna element bonded to said window glass and having an end at said recess; an active-circuit capsule having active electronic circuit components connectable to said radio and having at least one formation resiliently engageable and form-fitting in said recess with said capsule lying on said window glass over said recess; and means between said components of said capsule and said end of said antenna in said recess for connecting same together.
Claim 3
Dependent Claim
107 words
In a motor vehicle having a radio the improvement comprising the combination of: a window glass formed with a recess; an antenna element bonded to said window glass and having an end at said recess; an active-circuit capsule active electronic circuit components connectable to said radio and having at least one foot resiliently engageable in said recess with said capsule lying on said window glass over said recess; and means between said components of said capsule and said end of said antenna in said recess for connecting same together, said recess having a mouth at a surface of said window glass and is tapered toward said mouth.
Claim 4
Dependent Claim
107 words
In a motor vehicle having a radio the improvement comprising the combination of: a window glass formed with a recess; an antenna element bonded to said window glass and having an end at said recess; an active-circuit capsule active electronic circuit components connectable to said radio and having at least one foot resiliently engageable in said recess with said capsule lying on said window glass over said recess; and means between said components of said capsule and said end of said antenna in said recess for connecting same together, said recess having a mouth at a surface of said window glass and is tapered toward said mouth.
Claim 5
Dependent Claim
26 words
The improvement defined in claim 2 wherein said capsule has a plurality of such feet inwardly elastically deflectable toward one another when fitted into said recess.
Claim 6
Dependent Claim
47 words
The improvement defined in claim 3 wherein said window glass comprises a pair of glass layers and a plastic layer sandwiched therebetween, one of said glass layers being formed with a throughgoing hole constituting said recess, said antenna element being a wire imbedded in said plastic layer.
Claim 7
Dependent Claim
20 words
The improvement defined in claim 4 wherein said end of said element projects from said plastic layer into said recess.
Claim 8
Dependent Claim
24 words
The improvement defined in claim 5, further comprising a conductive mass at least partially filling said recess and in electrical contact with said end.
Claim 9
Dependent Claim
41 words
The improvement defined in claim 6 wherein said means includes at least one of said feet, said one foot being electrically conductive and being connected on one side to said components and being imbedded on the other side in said mass.
Claim 10
Dependent Claim
47 words
The improvement defined in claim 7 wherein said feet are angularly equispaced about and equispaced from an axis centered on said recess, said capsule having a flat face engageable with said window glass over said recess and said feet projecting from and diverging away from said face.
Claim 11
Dependent Claim
22 words
The improvement defined in claim 8 wherein said feet are bent inwardly toward each other at their ends remote from said face.
Claim 12
Dependent Claim
16 words
The improvement defined in claim 9 wherein said feet are formed of elastically resilient metal strips.
