Assignee: nan
Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 7:
8. A collision avoidance device, comprising:
a license plate frame configured to couple to a rear of a transport;
a first sensor mounted to the license plate frame to determine a distance between a following vehicle and the transport;
a second sensor mounted to the license plate frame to determine a velocity of the transport;
a logic circuit electrically coupled to the first sensor and the second sensor, wherein the logic circuit,
determines a safe trailing distance between the transport and the following vehicle based upon the velocity of the transport, and
determines whether the following vehicle is closer than the safe trailing distance to the transport;

a warning light coupled to the license plate frame to illuminate the license plate frame if the following vehicle is closer than the safe trailing distance to the transport; and
a camera coupled to the license plate frame and a memory coupled to the camera to record a video sequence;
an accelerometer coupled to the memory to terminate the video sequence after detection of an accelerometer signal indicative of a crash event.
