Histo-Cooling · Core technology

One device that closes the whole loop

Detect, respond, record, and adapt, all inside one fan-less, pump-less, disinfectant-wipeable IP68 device. Here is how it works.

Histo-Cooling concept cross-section

Concept cross-section: closed-loop response and a fully sealed passive-dissipation architecture (illustrative, not final appearance).

How the closed loop runs

01 · DETECT

Detect scratch

IMU, sleep state machine, and frequency-domain analysis identify valid scratch episodes.

02 · RESPOND

Active cooling

Cools the surface to break the itch-scratch cycle, bounded by a hard-coded safety envelope.

03 · RECORD

Signed data

Cryptographically signed time-series mapped to SCORAD / UAS7 / NRS endpoints.

04 · ADAPT

Efficacy feedback

Adjusts intensity by whether the response worked, clamped to the safety envelope.

Three interlocking layers

A · Method

Closed-loop method

A sleep state machine separates sleep states, frequency-domain analysis identifies valid scratch episodes, a closed-loop sequence triggers a response as it happens, and events map onto SCORAD / UAS7 / NRS endpoints.

B · Hardware

Hermetic cooling

Thermoelectric modules cool, a liquid-metal thermal bus carries heat away from the contact surface, a phase-change material buffers peak heat, and the shell dissipates it passively. No fan, no pump, no vents; IP68 and disinfectable.

C · Data & safety

Trustworthy data

A hard-coded safety envelope bounds the response, a sham mode supports double-blinding, a device-unique key signs the data, export is offline and point-to-point, and storage is fault-tolerant.

Data sovereignty & privacy

Data never leaves the device unverified

Stored locally, no internet, no auto-upload; export is local and point-to-point on user initiation, signed by a device-unique key inside a tamper-resistant secure element, which makes it inherently PIPL- and data-localization-compliant.

Device at the edge, analysis in the cloud

The device is fully offline and signs data locally; "cloud" refers only to the authorized research-analytics platform that verifies signatures, computes endpoints, and runs multi-site dashboards. Edge capture and cloud research each do their own job.
