Abstract
A system for warning of potential collisions among subjects includes devices configured to be transported by the subjects. At least one of the devices may have a device identifier and may include a transceiver configured to transmit radio frequency signals including the device identifier. At least one of the devices may include a processor operably connected to a transceiver configured to receive radio frequency signals. In at least one of the devices, the processor is configured to store another device'"'"'s identifier in a storage medium, to determine a signal strength of a radio frequency signal received from the other device, and to issue a warning signal based at least in part on at least one of the signal strength and the other device'"'"'s identifier. The warning signal is configured to warn a subject of a potential collision with another subject.

16. An apparatus configured to warn of a potential collision between a first subject and a second subject, the apparatus comprising:
-
a transceiver; a processor operably connected to the transceiver, where the processor is configured to cause the transceiver to transmit an outgoing signal comprising a device identifier, where the processor is further configured to receive from the transceiver incoming signals including a first incoming signal transmitted by a first apparatus, where the first incoming signal comprises a first device identifier, and a second incoming signal transmitted by a second apparatus, where the second incoming signal comprises a second device identifier, where the processor is configured to determine a first signal strength of the first incoming signal; where the processor is configured to determine a second signal strength of the second incoming signal; where the processor is further configured to issue a warning signal based at least in part on at least one of; (a) the first signal strength and the first device identifier, (b) the second signal strength and the second device identifier, and (c) the first signal strength, the first device identifier, the second signal strength and the second device identifier; and where the processor is further configured to compare the first signal strength to a preprogrammed threshold and issue the warning signal based at least in part on whether the first signal strength exceeds the preprogrammed threshold. - View Dependent Claims (17)
