Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 274 words
An apparatus for converting a motor vehicle plug-in audio unit into a remote playable unit which comprises: (a) a housing to receive the audio unit; (b) means within said housing for supplying DC power to the audio unit, said DC power supply means including a connector located within said housing for receiving a connector of the audio unit and a battery located within said housing and electrically connected to said housing connector for supplying DC power through the audio unit connector and into the audio unit and an AC to DC battery charger located within said housing and electrically connected to said battery and a power cord electrically connected to said battery charger and a power plug electrically connected to said power cord for taking AC current through said power cord into said battery charger for charging said battery when needed and an AC to DC transformer located within said housing and electrically connected to said housing connector and a transfer switch located on said housing and being electrically connected in a first mode between said power plug on said power cord and said battery charger and in a second mode between said power plug on said power cord and said transformer so that when said transfer switch is in said first mode said battery charger will operate and when said transfer switch is in said second mode said transformer will operate to supply DC power through the audio unit connector and into the audio unit; and (c) a pair of speakers electrically connected to the audio unit so that the audio unit can be played away from and independently of the motor vehicle.
Claim 2
Independent Claim 274 words
An apparatus for converting a motor vehicle plug-in audio unit into a remote playable unit which comprises: (a) a housing to receive the audio unit; (b) means within said housing for supplying DC power to the audio unit, said DC power supply means including a connector located within said housing for receiving a connector of the audio unit and a battery located within said housing and electrically connected to said housing connector for supplying DC power through the audio unit connector and into the audio unit and an AC to DC battery charger located within said housing and electrically connected to said battery and a power cord electrically connected to said battery charger and a power plug electrically connected to said power cord for taking AC current through said power cord into said battery charger for charging said battery when needed and an AC to DC transformer located within said housing and electrically connected to said housing connector and a transfer switch located on said housing and being electrically connected in a first mode between said power plug on said power cord and said battery charger and in a second mode between said power plug on said power cord and said transformer so that when said transfer switch is in said first mode said battery charger will operate and when said transfer switch is in said second mode said transformer will operate to supply DC power through the audio unit connector and into the audio unit; and (c) a pair of speakers electrically connected to the audio unit so that the audio unit can be played away from and independently of the motor vehicle.
Claim 3
Dependent Claim 23 words
An apparatus as recited in claim 1, further comprising a telescopic antenna located on said housing and electrically connected to said housing connector.
Claim 4
Dependent Claim 15 words
An apparatus as recited in claim 2, wherein said speakers are built into said housing.
Claim 5
Dependent Claim 41 words
An apparatus as recited in claim 3, further comprising: (a) a jack on said housing electrically connected to said housing connector; and (b) a pair of earphones with a plug to be removably connected to said jack to bypass said speakers.
Claim 6
Dependent Claim 68 words
An apparatus as recited in claim 2, wherein each of said speakers is an external remote speaker which includes: (a) a casing for holding said speaker; (b) an elongated cord electrically connected to said speaker and extending away from said casing; (c) a speaker plug electrically connected to free end of said elongated speaker cord; and (d) a socket located on said housing to receive said speaker plug.
Claim 7
Dependent Claim 60 words
An apparatus as recited in claim 2, further includes: (a) said housing having a front aperture and a pair of oppositely positioned slots on side walls thereof to receive a pair of tracks from side of the audio unit; and (b) a latch member on said housing adjacent said front aperture to hold the audio unit securely within said housing.
Claim 8
Dependent Claim 28 words
An apparatus as recited in claim 6, further comprising an adapter connector to plug into said housing connector so as to receive any type of audio unit connector.
Claim 9
Dependent Claim 71 words
An apparatus as recited in claim 6, further includes: (a) a plurality of springs, each of which is mounted to one side of said housing within the aperture; and (b) a plurality of plates, each of which is mounted to free end of one of said springs so that any sized audio unit can be placed into the aperture and be held by said plates so as to properly fit therein.
Claim 10
Dependent Claim 74 words
An apparatus as recited in claim 6, further includes: (a) a plurality of adjustment screws, each of which is threadably mounted through one side of said housing into the aperture; and (b) a plurality of plates, each of which is mounted to free end of one of said adjustment screws so that any sized audio unit can be placed into the aperture and be held by said plates so as to properly fit therein.
