Collision avoidance signaling from mobile devices
First Claim
1. A method comprising:
- determining at a first system, at a first time, a location of a target associated with the first system;
constructing a signal, data of the signal comprising an identifier indicative of a collision avoidance nature of the signal;
determining an amount of ambient light around the target;
causing an increase, at a transmitter module in the first system, responsive to the amount of ambient light being less than a threshold amount, a transmission power for broadcasting the signal; and
broadcasting the signal from the first system, the broadcasting causing a second system to receive the signal.

Abstract
A location of a target associated with a first system is determined at the first system at a first time. A signal is constructed at the first system where the data of the signal includes an identifier indicative of a collision avoidance nature of the signal. The signal is broadcast from the first system. the broadcasting causes a second system to receive the signal; compute a likelihood of a collision between the first system and the second system using the location from the signal, a velocity of the first system, a location of the second system at the first time, and a velocity of the second system at the first time; and send a notification from the second system about the likelihood of collision when the likelihood of collision exceeding a threshold likelihood.
