Personal heat-risk intelligence at the edge.
CoreSense is a worker-safety prototype that combines on-wrist sensing, site conditions, conservative decision rules, clear worker actions, supervisor escalation, and a reviewable event record.
View the live CoreSense experience
Heat strain can build before a worker or supervisor sees an obvious problem. CoreSense is designed to turn that uncertainty into one operational loop:
Sense -> Estimate -> Decide -> Act -> Record
- Sense: collect worker and site signals without sending raw optical data off the band.
- Estimate: derive a personal thermal-strain estimate using the documented Buller heart-rate-to-ECTemp model.
- Decide: combine the estimate, signal quality, trend, and site WBGT through conservative rules.
- Act: show a direct on-wrist instruction such as
BAND OK,CAUTION, orREST NOW. - Record: preserve acknowledgements, escalations, recovery events, and important uncertainty for review.

CoreSense is a safety decision-support prototype. It is not a clinical thermometer or medical device, and the current materials do not establish clinical accuracy, field effectiveness, assembled-device runtime, durability, or certification.
The interface keeps those limits visible. It presents personal guidance as one input beside site WBGT, existing heat controls, trained supervision, and established emergency procedures.
The deployed site includes a searchable document reader backed by public/docs. Every source link opens inside the CoreSense experience, so architecture, science, validation, bill-of-materials, pilot, field-footage, and outreach documents can be reviewed without downloading the repository.
The library is indexed in app/docs-manifest.ts and rendered by app/DocumentLibrary.tsx with GitHub-flavored Markdown support.
