Abstract
Abstract Proximity radar mounted in a vehicle determines the location of other vehicles. Other vehicles detect their own positions and broadcast those positions to all surrounding vehicles. Vehicle position data is plotted on a moving map so the driver can see the location of other vehicles, in some cases with an icon color which matches vehicle color(s). A driver can open a communication link with drivers who are projected to constitute a collision threat. A fixed radar unit can be positioned at blind intersections and broadcast vehicle location information for vehicles not equipped with the ability to track their own locations.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
93 words
Apparatus mounted in a vehicle for avoiding collisions, comprising: a. a GPS receiver; b. a transceiver; and c. a computer connected to said GPS receiver and to said transceiver and configured to receive location information from said GPS receiver and transmit it over said transceiver for reception by other vehicles and to receive location information from at least one vehicle together with color information specifying the color of said at least one vehicle in which vehicle locations are displayed on a display device in one or more colors specified by said color information.
Claim 2
Dependent Claim
93 words
Apparatus mounted in a vehicle for avoiding collisions, comprising: a. a GPS receiver; b. a transceiver; and c. a computer connected to said GPS receiver and to said transceiver and configured to receive location information from said GPS receiver and transmit it over said transceiver for reception by other vehicles and to receive location information from at least one vehicle together with color information specifying the color of said at least one vehicle in which vehicle locations are displayed on a display device in one or more colors specified by said color information.
Claim 3
Dependent Claim
113 words
Apparatus mounted in a vehicle for avoiding collisions, comprising: a. a GPS receiver; b. a transceiver; and c. a computer connected to said GPS receiver and to said transceiver and configured to receive location information from said GPS receiver and transmit it over said transceiver for reception by other vehicles, in which said computer is configured to determine which, if any, other vehicles constitute a collision threat based on location information received from said vehicles over said transceiver and to establish an audio communication link between an operator of the vehicle automatically with at least one of said other vehicles if said at least one of said other vehicles constitutes a collision threat.
Claim 4
Dependent Claim
113 words
Apparatus mounted in a vehicle for avoiding collisions, comprising: a. a GPS receiver; b. a transceiver; and c. a computer connected to said GPS receiver and to said transceiver and configured to receive location information from said GPS receiver and transmit it over said transceiver for reception by other vehicles, in which said computer is configured to determine which, if any, other vehicles constitute a collision threat based on location information received from said vehicles over said transceiver and to establish an audio communication link between an operator of the vehicle automatically with at least one of said other vehicles if said at least one of said other vehicles constitutes a collision threat.
Claim 5
Independent Claim
110 words
A system for avoiding collisions, comprising: a. a plurality of vehicles equipped with a receiver for determining vehicle location, at least one of which is also equipped with a proximity radar; b. said vehicles each having a transceiver for transmitting its location and receiving location information from other vehicles and a computer for determining from received location information, if received location information is available, or from location information provided by said proximity radar, if received location information is not available, or from both received location information and proximity radar, whether another vehicle constitutes a collision threat; and c. an alarm for alerting a vehicle operator if a collision threat exists.
Claim 6
Independent Claim
110 words
A system for avoiding collisions, comprising: a. a plurality of vehicles equipped with a receiver for determining vehicle location, at least one of which is also equipped with a proximity radar; b. said vehicles each having a transceiver for transmitting its location and receiving location information from other vehicles and a computer for determining from received location information, if received location information is available, or from location information provided by said proximity radar, if received location information is not available, or from both received location information and proximity radar, whether another vehicle constitutes a collision threat; and c. an alarm for alerting a vehicle operator if a collision threat exists.
Claim 7
Dependent Claim
17 words
The method apparatus system of claim 3, in which the proximity radar is a micropower impulse radar.
Claim 8
Independent Claim
78 words
A method of avoiding collisions, comprising the steps of: a. providing an element for performing a step of receiving vehicle location information from other vehicles; b. providing an element for performing a step of calculating whether a vehicle is a collision threat based on received location information; and c. providing an element for performing the step of automatically establishing an audio communication link between vehicle operators if that vehicle is a vehicle associated with a calculated collision threat.
Claim 9
Independent Claim
78 words
A method of avoiding collisions, comprising the steps of: a. providing an element for performing a step of receiving vehicle location information from other vehicles; b. providing an element for performing a step of calculating whether a vehicle is a collision threat based on received location information; and c. providing an element for performing the step of automatically establishing an audio communication link between vehicle operators if that vehicle is a vehicle associated with a calculated collision threat.
Claim 10
Dependent Claim
66 words
A computer program product, comprising: a. a memory medium; and b. a computer program stored on said memory medium, said program comprising instructions for receiving vehicle location information from other vehicles, calculating whether a vehicle is a collision threat based on received location information, and automatically establishing an audio communication link between vehicle operators if that vehicle is a vehicle associated with a calculated collision threat.
Claim 11
Dependent Claim
