Methods and systems for alerting persons of obstacles or approaching hazards
First Claim
1. A warning system, comprising:
- a radio source configured to transmit a radio signal; and
a warning device, comprising,at least one vibration device;
at least two receiver devices configured to receive the radio signal; and
a processing device operably coupled to at least two receiver devices and at least one vibration device, wherein the processing device is configured to determine at least a direction and a distance to the radio source from the warning device and configured to transmit a vibration signal to at least one vibration device based upon the determined direction and distance to the radio source from the warning device,wherein the direction is based at least in part on the relative signal strength of the radio signal detected by the two receiver devices.
