In many instances, attacks start from behind, exploiting a weakness in our forward-facing vision system. To address this, the present inventor devised, among other things, a rear-facing clip-on sensor that attaches to the back of a user, detecting rear-approaching objects or persons, and vibrating or beeping to alert the user. In some embodiments, the clip-on sensor includes a digital camera and a wireless transceiver to communicate with a smartphone or smartwatch, not only allowing the smartphone or smartwatch to alert the user via audible, visible, and/or tactile (haptic) alarms, but also to send SOS signals and real-time audio and/or video signals to designated persons or security services."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems, methods, components, and software for detection and/or display of rear security threats","description":"Across the planet, the fear of physical attacks is experienced daily by millions of men and women, especially those walking or running alone in secluded areas.
