Example mobile electronic devices of the present disclosure can include a non-transitory computer-readable medium having computer-readable instructions stored thereon, and a processor coupled to the non-transitory computer-readable medium. The processor executes the instructions to calculate a distance between a reference location and a current location, and calculate a travel time for the distance based on a speed. The processor also executes the instructions to determine a nature event time and cause a return alert indication to be signaled, via the mobile electronic device, based on a comparison of a calculated travel time and the nature event time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nature event signaling","description":"Methods and apparatus for nature event signaling are provided.
