EVENT-RECORDER FOR TRANSMITTING AND STORING ELECTRONIC SIGNATURE DATA
First Claim
1. An electronic event recorder for monitoring vehicles, comprising:
- sensor means for sensing the occurrence of an event;
a memory for storing signature data related to a vehicle;
at least one of a transmitter and receiver, said transmitter for transmitting said signature data upon the occurrence of an event detected by said sensor means, said receiver for receiving data from a remote transmitter; and
a microprocessor for controlling said sensor means, said memory, said transmitter and said receiver, wherein upon the occurrence of an event sensed by said sensor means, said microprocessor causes said transmitter to transmit said signature data to a remote receiver.

Abstract
An electronic event recorder for attachment to a vehicle is provided which can broadcast encrypted signature and data, thereby leaving behind an electronic version of a “fingerprint” in the event of an accident or traffic violation. The fingerprint, captured by an external data acquisition system or another vehicle so equipped, provides a history of events related to the vehicle. The event recorder is preferably integrated on a smart card and housed in a tamper proof casing. In a first mode of operation, monitoring stations along the roadways periodically send an interrogation signal, such as when radar detects that the vehicle is speeding. Upon receiving the interrogation signal the smart card transmits the vehicle'"'"'s signature information to the monitoring station where it is time and date stamped along with the speed of the vehicle. In a second mode of operation, when a sensor detects a sudden or violent acceleration or deceleration, such as occurs during a collision, a smart card mounted in each car will exchange signature information automatically. This is particularly useful when the collision occurs in a parking lot when one of the hit vehicles is typically unattended.

14. A system for monitoring vehicles, comprising:
-
a first event recorder carried by a first vehicle;
a second event recorder carried by one of a second vehicle and a roadside monitoring station;
said first event recorder comprising;
a first event sensor means for sensing an event;
a first memory for storing vehicle signature data; and
a first transceiver for transmitting vehicle signature data to, and receiving signature data from, said second event recorder;
said second event recorder comprising;
a second memory for storing vehicle signature data; and
a second transceiver for transmitting data to, and receiving vehicle signature data from, said first event recorder, wherein when said first event sensor means senses an event, said first event recorder transmits its vehicle signature data stored in said first memory to said second transceiver in said second event recorder to be stored in said second memory.

21. A method for exchanging vehicle signature data upon the occurrence of an event, comprising the steps of:
-
detecting an interrogation signal from a remote station;
transmitting first vehicle signature data if said interrogation signal is detected to said remote station;
detecting one of an acceleration and deceleration exceeding a threshold value indicating a collision has occurred with a second vehicle and, if a collision has occurred;
transmitting said first vehicle signature data to be stored in a memory in said second vehicle; and
transmitting second vehicle signature data to be stored in a memory in said first vehicle. - View Dependent Claims (22, 23, 24, 26, 27, 28, 29, 30)
