RESCUE DEVICE AND RESCUE METHOD
A portable rescue device (PRD) includes, a sensor, a display unit, and a wireless receiver configured to receive a distress signal from a portable distress device (PDD). The PRD further includes a processor communicably coupled to each of the display unit, the wireless receiver, and the sensor. The processor is configured to determine one or more path obstacles disposed in a first direction between the wireless receiver and the PDD along which the distress signal has a maximum signal strength based on an obstacle signal generated by the sensor. The processor is further configured to determine at least one obstacle-free path unobstructed by the one or more path obstacles. The processor is further configured to determine at least one set of guiding directions for guiding the user along the at least one obstacle-free path. The processor is further configured to display the at least one set of guiding directions.
