Per-subject baseline monitoring
Within-subject reference distributions built from continuous physiological signal, as a basis for detecting change.
Capability statement
Selected, trained and conditioned personnel are the population for whom a general reference range is least meaningful. Intuitive Pathos is developing physiological monitoring designed to establish each operator’s own baseline and report departure from it in both directions, weighted equally.
The problem
Physiological thresholds in general use are derived from general populations. Operators in high-consequence roles are, by selection and by training, not drawn from that distribution, and the specific adaptations that make them effective are exactly the ones that make a population range misleading for them.
The result is an instrument that under-detects in the people it is most important to monitor, and over-flags in ways that erode trust in the system until it is ignored.
The harder problem
Fatigue, thermal strain, hypoxia, dehydration and accumulated load rarely announce themselves as a spike. They present as flattening: reduced variability, slower recovery, a narrowing of normal response. That is the critical-slowing-down signature set out on the evidence page. Conventional monitoring is tuned to the loud direction.
The operator is also, reliably, the last person to recognize it in themselves. Self-report is the least available signal exactly when it matters most.
Core competencies
Within-subject reference distributions built from continuous physiological signal, as a basis for detecting change.
Memory coefficient, critical slowing down, λ* criticality and sliding-window regime detection are established dynamical-systems early-warning methods that Pathos Guardian is being designed to apply to operator state. See the lineage.
Elevated and suppressed departures are designed to be weighted identically, so that degradation presenting as flattening is not discounted by construction.
The methods work on continuous physiological signal. The sensing a given program would need is scoped with that program.
What may leave a deployment and what may never leave it is expressed in the type system, not in configuration. There is no setting that enables the prohibited case.
Demographic group membership is kept out of the model input by design, and that separation is inspectable at the interface level, which is relevant to emerging requirements on algorithmic accountability in federal systems. Per-group accuracy has not yet been measured.
Data posture
For defense deployments, the question is never whether a vendor promises to keep data in place. It is whether the system is capable of moving it. We designed for the second question.
Per-subject baselines and identifiable physiological data do not cross the federation boundary. That constraint is enforced in the typed federation contract shared by client and server, which means it is not a deployment option, an environment variable, or a default a configuration error could reverse.
Deployment topology, including fully disconnected and air-gapped operation, is a program-level decision we expect to accommodate rather than negotiate.
Pathos Guardian is a non-clinical system. It does not diagnose, does not generate a medical record, and does not make fitness-for-duty or employment determinations.
Those boundaries are architectural: the clinical decision logic is not present in the product’s dependency graph.
A monitoring system that operators believe can be used against them will be defeated by the operators. What the system can emit about an individual is deliberately limited, and we regard that as a capability requirement rather than an ethical nicety.
Differentiators
Not a cohort, not a percentile, not a demographic model. This is a different measurement, not a better-tuned version of the standard one.
The methods come from clinical monitoring, developed by a registered nurse with about ten years of bedside practice, mostly in inpatient psychiatric and neuroscience care. The defense product is deliberately scoped to stay out of clinical territory.
Our data-boundary constraints are inspectable at the interface level. A technical evaluator can check them rather than take them on assurance.
The same core is under development for clinical, veterinary and consumer settings, so the defense line would benefit from evidence and hardening as those programs generate it outside the defense budget.
Contracting
We can provide a formatted capability statement, current registration details, and technical materials suited to a specific solicitation or teaming discussion.
Pathos Guardian is in development and is not currently available for operational deployment. Nothing on this page constitutes a representation of past performance.
