Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 124 words
For use in combination with a marine or land vehicle having a low voltage circuit powered from a low voltage power supply, propulsion means connected to the low voltage circuit, and a high voltage circuit for connection to an external standard domestic power supply, a power supply warning device comprising: a. warning means connectable to one of said low voltage or said high voltage circuits, and b. means operated by the other of said circuits in response to energization of said other circuit to connect said warning means to said one circuit to cause said warning means to warn against moving the vehicle when both said circuits are energized and to warn to disconnect the high voltage circuit from the external domestic power supply.
Claim 2
Dependent Claim 124 words
For use in combination with a marine or land vehicle having a low voltage circuit powered from a low voltage power supply, propulsion means connected to the low voltage circuit, and a high voltage circuit for connection to an external standard domestic power supply, a power supply warning device comprising: a. warning means connectable to one of said low voltage or said high voltage circuits, and b. means operated by the other of said circuits in response to energization of said other circuit to connect said warning means to said one circuit to cause said warning means to warn against moving the vehicle when both said circuits are energized and to warn to disconnect the high voltage circuit from the external domestic power supply.
Claim 3
Dependent Claim 18 words
The power supply warning device of claim 1 wherein the low voltage circuit further comprises an ignition circuit.
Claim 4
Dependent Claim 18 words
The power supply warning device of claim 1 wherein the low voltage circuit further comprises a starter circuit.
Claim 5
Dependent Claim 19 words
The power supply warning device of claim 1 wherein said warning means includes both visual and audial warning devices.
Claim 6
Dependent Claim 33 words
The power supply warning device of claim 1 wherein said warning means further comprises disabling means for disabling at least a portion of the vehicle propulsion means when both said circuits are energized.
Claim 7
Dependent Claim 43 words
The power supply warning device of claim 5 wherein the vehicle propulsion means includes a direction shifting mechanism having a neutral position, and wherein said disabling means further comprises means for locking the shifting mechanism in neutral when both said circuits are energized.
Claim 8
Dependent Claim 38 words
The power supply warning device of claim 5 wherein the vehicle propulsion means includes a starter mechanism, and wherein said disabling means further comprises means for interrupting power to the starter mechanism when both said circuits are energized.
Claim 9
Dependent Claim 110 words
For use in combination with a marine or land vehicle having a low voltage circuit powered from a low voltage power supply, propulsion means connected to the low voltage circuit, and a high voltage circuit for connection to an external standard domestic power supply, a power supply warning device comprising: a. warning means connectable to and powered by the high voltage circuit, and b. means operated by the low voltage circuit in response to energization thereof to connect said warning means to the high voltage circuit to cause said warning means to warn against moving the vehicle when the high voltage circuit is connected to an external domestic power supply.
Claim 10
Dependent Claim 110 words
For use in combination with a marine or land vehicle having a low voltage circuit powered from a low voltage power supply, propulsion means connected to the low voltage circuit, and a high voltage circuit for connection to an external standard domestic power supply, a power supply warning device comprising: a. warning means connectable to and powered by the high voltage circuit, and b. means operated by the low voltage circuit in response to energization thereof to connect said warning means to the high voltage circuit to cause said warning means to warn against moving the vehicle when the high voltage circuit is connected to an external domestic power supply.
Claim 11
Dependent Claim 51 words
The power supply warning device of claim 8 wherein said warning means further comprises disabling means for disabling at least a portion of the vehicle propulsion means when said warning means is connected to the high voltage circuit and the high voltage circuit is connected to an external domestic power supply.
Claim 12
Dependent Claim 143 words
For use in combination with a self-propelled marine or land vehicle having an internal DC power supply, and internal combustion engine for propelling the vehicle, a DC starter and starter circuit for the engine, an ignition circuit for the engine powered by the DC power supply, a direction shifting mechanism having a neutral position, and an accessory circuit for connection to an external standard domestic power supply of approximately 110-120 volts AC, a power supply warning device comprising: a. warning indicator means for indicating that the accessory circuit is connected to an external standard domestic power supply, and b. DC relay means operated by one of the ignition and starter circuits to connect said warning indicator means to the accessory circuit when the one circuit is energized, to warn to disconnect the accessory circuit from the external domestic power supply when so connected.
Claim 13
Dependent Claim 143 words
For use in combination with a self-propelled marine or land vehicle having an internal DC power supply, and internal combustion engine for propelling the vehicle, a DC starter and starter circuit for the engine, an ignition circuit for the engine powered by the DC power supply, a direction shifting mechanism having a neutral position, and an accessory circuit for connection to an external standard domestic power supply of approximately 110-120 volts AC, a power supply warning device comprising: a. warning indicator means for indicating that the accessory circuit is connected to an external standard domestic power supply, and b. DC relay means operated by one of the ignition and starter circuits to connect said warning indicator means to the accessory circuit when the one circuit is energized, to warn to disconnect the accessory circuit from the external domestic power supply when so connected.
Claim 14
Dependent Claim 54 words
The power supply warning device of claim 10 wherein said warning indicator means further comprises: a. indicator bulb and buzzer means, and b. disabling means for disabling at least a portion of the vehicle propulsion means when the one circuit is energized and the accessory circuit is connected to an external domestic power supply.
Claim 15
Dependent Claim 43 words
The power supply warning device of claim 11 wherein said disabling means further comprises latch and pin means for locking the shifting mechanism in neutral when the ignition circuit is energized and the accessory circuit is connected to an external domestic power supply.
Claim 16
Dependent Claim 40 words
The power supply warning device of claim 11 wherein said disabling means further comprises means for interrupting power to the engine starter when the starter circuit is energized and the accessory circuit is connected to an external domestic power supply.
Claim 17
Dependent Claim 40 words
The power supply warning device of claim 11 wherein said disabling means further comprises means for interrupting power to the engine starter when the ignition circuit is energized and the accessory circuit is connected to an external domestic power supply.
