Abstract
Abstract An anti theft vehicle system for motor vehicles and the like is provided which uses a magnetically or optically encoded card inserted into a card reader mounted in the vehicle to limit operation of the vehicle. The vehicle ID number is stored in a control computer along with continuously updated date and time. If the vehicle ID of the card and computer match, and the data and time are within the authorized operation date and time encoded on the card, the vehicle will operate. The remaining time of authorized use is displayed. If there is no match the vehicle ignition and fuel line are blocked and hood is locked thereby foiling any attempt to circumvent this security system by bypassing it. Should the operator inadvertently leave the card in the reader while attempting to leave the vehicle the vehicle ignition will continue to operate until the card is removed thereby reminding the operator to remove the card. Additional data may be encoded upon the card for purposes of accounting or inventory control.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
An anti theft system for motor vehicles and the like, comprising: (a) a computer control which contains a date/time clock and has in its memory a vehicle ID number; (b) a card reader/time display input/output device which converts information stored on a card into electrical signals decodeable by said computer control and displays the time remaining for the operation of said motor vehicle and the like; and (c) at least one output vehicle shutdown device wherein said output device is controllable by said computer control, and wherein said card reader/time display comprises a magnetic card reader whereby said magnetic card reader will prevent the enabling of an ignition shutoff until a magnetic card is removed thereby discouraging an operator from leaving said vehicle without first removing said magnetic card.
Claim 2
Dependent Claim
129 words
An anti theft system for motor vehicles and the like, comprising: (a) a computer control which contains a date/time clock and has in its memory a vehicle ID number; (b) a card reader/time display input/output device which converts information stored on a card into electrical signals decodeable by said computer control and displays the time remaining for the operation of said motor vehicle and the like; and (c) at least one output vehicle shutdown device wherein said output device is controllable by said computer control, and wherein said card reader/time display comprises a magnetic card reader whereby said magnetic card reader will prevent the enabling of an ignition shutoff until a magnetic card is removed thereby discouraging an operator from leaving said vehicle without first removing said magnetic card.
Claim 3
Dependent Claim
21 words
An anti theft system for motor vehicles and the like, as recited in claim 1, further comprising a magnetic encoded card.
Claim 4
Dependent Claim
86 words
An anti theft system for motor vehicles and the like, as recited in claim 2, wherein the information stored on said magnetic card comprises a vehicle ID number and a card use expiration date such that said computer control compares said vehicle ID number and the current date/time to that contained in said magnetic card thereby disabling said ignition shutoff, fuel line shutoff and hood lock should a match occur and thereby enabling said ignition shutoff, fuel line shutoff and hood lock should a mismatch occur.
Claim 5
Dependent Claim
33 words
An anti theft system for motor vehicles and the like, as recited in claim 2, wherein the information stored on said magnetic card further comprises optional information useful for accounting and inventory control.
Claim 6
Dependent Claim
129 words
An anti theft system for motor vehicles and the like, comprising: (a) a computer control which contains a date/time clock and has in its memory a vehicle ID number; (b) a card reader/time display input/output device which converts information stored on a card into electrical signals decodeable by said computer control and displays the time remaining for the operation of said motor vehicle and the like; and (c) at least one output vehicle shutdown device wherein said output device is controllable by said computer control, and wherein said card reader/time display comprises an optical card reader whereby said optical card reader will prevent the enabling of an ignition shutoff until an optical card is removed thereby discouraging an operator from leaving said vehicle without first removing said optical card.
Claim 7
Dependent Claim
129 words
An anti theft system for motor vehicles and the like, comprising: (a) a computer control which contains a date/time clock and has in its memory a vehicle ID number; (b) a card reader/time display input/output device which converts information stored on a card into electrical signals decodeable by said computer control and displays the time remaining for the operation of said motor vehicle and the like; and (c) at least one output vehicle shutdown device wherein said output device is controllable by said computer control, and wherein said card reader/time display comprises an optical card reader whereby said optical card reader will prevent the enabling of an ignition shutoff until an optical card is removed thereby discouraging an operator from leaving said vehicle without first removing said optical card.
Claim 8
Dependent Claim
21 words
An anti theft system for motor vehicles and the like, as recited in claim 5, further comprising an optically encoded card.
Claim 9
Dependent Claim
88 words
An anti theft system for motor vehicles and the like, as recited in claim 6, wherein the information stored on said optically encoded card comprises a vehicle ID number and a card use expiration date such that said computer control compares said vehicle ID number and the current date/time to that contained in said optically encoded card thereby disabling said ignition shutoff, fuel line shutoff and hood lock should a match occur and thereby enabling said ignition shutoff, fuel line shutoff and hood lock should a mismatch occur.
Claim 10
Dependent Claim
33 words
An anti theft system for motor vehicles and the like, as recited in claim 6, wherein the information stored on said optical card further comprises optional information useful for accounting and inventory control.
