Abstract
Conventional wrist-worn collision detectors suffer from high false-alarm rates due to daily hand movement noise and cannot verify whether a physical device remains coupled to a user during a high-impact deceleration event. To address these limitations, a head-wearable spectacles frame is configured with a dual-stage accelerometer array, a conductive capacitive temple skin-contact sensor array, a micro-barometric cabin classifier configured to execute a closed-cabin emergency override process, a localized peer-to-peer group mesh transceiver, and an autonomous direct-to-satellite micro-radio-frequency (RF) transceiver. High-G collision monitoring is gated by an open-air velocity precursor and verified by unbroken facial skin impedance prior to an impact. Pyrotechnic airbag overpressure waves are evaluated to override open-air velocity filters during passenger cabin collisions. Upon verification of an impact event, emergency telemetry is dispatched across localized peer-to-peer group networks and directly to satellite networks or 406 MHz search-and-rescue via a conformal temple slot radiator antenna with dynamic ejection impedance tuning. Consequently, false alarms from drops or benign movements are suppressed while phone-independent emergency distress signaling is maintained during severe collisions.
