First Claim
1. A system for warning of potential collisions among a plurality of subjects, the system comprising:
- a plurality of devices including at least;
a first device configured to be transported by a first subject, where the first device has a first device identifier, and where the first device includes;
a first transceiver configured to transmit a first radio frequency signal including the first device identifier,a first processor operably connected to the first transceiver, anda first storage medium operably connected to the first processor; and
a second device configured to be transported by a second subject, where the second device has a second device identifier, and where the second device includes;
a second transceiver configured to transmit a second radio frequency signal including the second device identifier,a second processor operably connected to the second transceiver, anda second storage medium operably connected to the second processor;
where the first transceiver is configured to receive radio frequency signals including the second radio frequency signal, where the first processor is configured to store the second device identifier in the first storage medium, where the first processor is configured to determine a second signal strength of the received second radio frequency signal, and where the first processor is configured to issue a first warning signal based at least in part on at least one of the second signal strength and the second device identifier, where the first warning signal is configured to warn the first subject of a potential collision between the first subject and the second subject; and
where the second transceiver is configured to receive radio frequency signals including the first radio frequency signal, and where the second processor is configured to store the first device identifier in the second storage medium, where the second processor is configured to determine a first signal strength of the received first radio frequency signal.

Abstract
A method for avoiding collisions may include receiving a signal from a device, where the signal includes an identifier of the device transmitting the signal. The method for avoiding collisions may further include determining strength of the signal. The method for avoiding collisions may further include reading from a database a threshold corresponding to an allowable distance to the device. The method for avoiding collisions may further include comparing the threshold to one of the determined strength of the signal and an approximate distance of the device calculated based on the determined strength of the signal. The method for avoiding collisions may further include issuing a collision warning if the one of the determined strength of the signal and the approximate distance of the device exceeds the threshold.
