ResQWatch: A Bluetooth-Enabled App Based Wearable GPS-Aware Extension for Rapid Emergency Trigger and Automated Police Dispatch.

This work’s contributions, briefly:
1) A debounce-checked double-press gesture with an explicit timing-window model, so accidental single knocks
and switch bounce don’t get treated as real triggers.
2) An auto-reconnecting BLE 5.0 relay that hands a distress
record from a phone-independent wearable to a bonded
companion app, without the onboard GPS/GSM hardware that dominates cost and power draw in most prior
designs.
3) A cloud dispatch scheme that runs geofenced community notification and automated nearest-station police
contact at the same time, using Haversine-distance POI
lookup.
4) A full application stack, React Native app, .NET services, PostgreSQL, plus everyday features (a social
safety feed, a government notice board) meant to keep
the app open on ordinary days, not just emergencies.
5) A theoretical, stage-by-stage latency budget for the
whole press-to-dispatch chain, built from BLE spec timing and datasheet figures presented honestly as design
targets, not measured numbers.
