The PULSE layer runs five domain variants sharing a common architecture.
The data schema, the time base and synchronisation method, the alert taxonomy structure, and the analytics stack. A model improvement in one domain applies to the others.
Pulse.Land prioritises heat strain trajectory, toxic exposure and cognitive load for CBRN, polar, firefighting and tactical operators, streaming fused operator state to command.
Pulse.Sea prioritises depth and pressure, dissolved gas tracking, thermal loss and cognitive impairment. Inert gas narcosis impairs the faculty a diver would use for self-assessment, which is why objective measurement carries weight at depth.
Pulse.Air prioritises blood oxygen saturation, hypoxia onset, G-tolerance and cumulative fatigue across sortie sequences. Individual hypoxia susceptibility varies enough that physiological measurement detects onset earlier than fixed altitude rules.
Pulse.Space prioritises consumables, suit pressure integrity and EVA metabolic rate.
Pulse.Joint fuses all four for multi-domain operations.
The taxonomy separates advisory notifications, cautions requiring acknowledgment, warnings requiring action within a stated window, and abort criteria.
Each alert carries a documented trigger condition, detection threshold, required response and false positive rate established during validation.
A core temperature reading states current condition. A projected time to threshold supports a decision.
That projection runs on physiological models validated against occupational health frameworks including the NIOSH heat criteria, connecting into digital twin capability.
Sensing accuracy characterised on human surrogates in environmental rigs applies across variants. Environmental envelope and threshold validation are domain-specific.
