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: 9
Claim 1
Independent Claim
83 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 together with vehicle color
information from other vehicles in which vehicle
locations are displayed on a display device in one or
more colors specified by said color information.
Claim 2
Dependent Claim
100 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 automatically with at least one of said other
vehicles if it constitutes a collision threat.
Claim 3
Dependent Claim
59 words
Apparatus, mounted near an intersection, for
avoiding collisions, comprising: a. a proximity radar; b. a transceiver; and c. a computer connected to said proximity radar and
to said transceiver and configured to receive vehicle
location information from said proximity radar and
transmit the location of vehicles detected by said
proximity radar over said transceiver for reception by
other vehicles.
Claim 4
Independent Claim
44 words
A method of avoiding collisions, comprising the
steps of: a. providing an element for performing a step of
locating vehicles using a proximity radar; and b. providing an element for performing a step of
transmitting vehicle locations detected using proximity
radar to other vehicles.
Claim 5
Independent Claim
88 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 or from
location information provided by said 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
Dependent Claim
58 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 and from
a proximity radar, calculating whether a vehicle is a
collision threat based on said location information, and
alerting an operator if a collision threat exists.
Claim 7
Dependent Claim
39 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 identifying
vehicle locations using a proximity radar and
transmitting said vehicle locations to other vehicles.
Claim 8
Independent Claim
73 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
with another vehicle if that vehicle constitutes a
collision threat.
Claim 9
Dependent Claim
39 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 establishing an
audio communication link with a vehicle if that vehicle
constitutes a collision threat.
