When Disaster Strikes
Earthquake, typhoon, battlefield — when the network goes down, xGrid is the last line of defense.
Network Down
Earthquake collapses cell towers. Typhoon cuts fiber lines. Cloud services become unreachable — but patients still need care.
Equipment Damaged
Flooding, lightning, shelling — when equipment is damaged and data becomes inaccessible, you need a system that already lives on every device.
Field Operations
Remote disaster sites, mobile clinics, forward operating bases — no stable network, but nurses can run the full patient workflow from a phone.
De Novo xGrid: Built for the Worst
An offline-first medical platform on a credit-card-sized Raspberry Pi. Nurses operate the full patient workflow from their phones — registration, triage, surgery, transfusion, discharge billing. Sync when connected, operate independently when not.
Built for Real Disasters
Designed with input from emergency responders and medical professionals
Walkaway Test
If the dev team dissolves and servers shut down, can the system keep running? We validate with 5 tests.
Lifeboat Protocol
When the hub fails, edge devices can rebuild the system.
Like a starfish regenerating a limb, every De Novo xGrid edge device can rebuild the central brain.
When designing a system, assume you'll be hit by a bus tomorrow. Can your users continue without you? This is our standard for every line of code.
149-Step Automated Test — 10 Patient Scenarios
The most demanding test: 3 of 8 medical stations forced to evacuate simultaneously — with active blood transfusions and an ongoing surgery. The system ensured every patient record, blood bag, and medication transfer was tracked and verified, without interrupting care.
Validated on Raspberry Pi 5 · 20 concurrent stations · zero errors

Three scenarios for high flexibility and resilience
Nhân nội bộ (Kernel)
Máy chủ tại chỗ cho phép mọi điện thoại trong trạm chia sẻ cùng dữ liệu
SDK giải quyết phối hợp giữa các PWA trên cùng một thiết bị. Nhưng khi một trạm y tế có 5 y tá, 3 bác sĩ và 2 nhân viên hậu cần làm việc trên các điện thoại khác nhau cùng lúc, ai đảm bảo dữ liệu bệnh nhân nhất quán cho tất cả? Đó là Kernel — một Raspberry Pi nhỏ bằng thẻ tín dụng chạy như máy chủ tại chỗ trong mỗi trạm. Mọi điện thoại kết nối qua Wi-Fi trạm, không cần internet bên ngoài, mọi PWA chia sẻ cùng dữ liệu theo thời gian thực.
SDK — Phối hợp cùng thiết bị
Thư viện mã chung cho mọi PWA trên một thiết bị đồng bộ cross-tab thời gian thực
Kernel — Phối hợp cùng trạm
Raspberry Pi tại chỗ cho phép nhiều thiết bị trong một trạm chia sẻ cùng nguồn dữ liệu bệnh nhân
Mesh — Phối hợp xuyên trạm
Cấu trúc Hub-Spoke cho phép các trạm dự phòng lẫn nhau và khôi phục sau thảm họa
Community Grid
CIRS EngineCommand center for community resilience. Orchestrate shelter operations, coordinate volunteer dispatch, delivery tracking (offline ledger + contract pricing)—all offline.
Medical Grid
MIRS EngineCritical medical data, even offline. Complete patient records, real-time triage classification, medication inventory tracking.
xGrid READY
Making resilience part of everyday life. Free offline-first supply management app for families.
Built for Every Role
From field medics to command center operators, De Novo xGrid adapts to your workflow.
Clinical Ops
Seamless patient handoff from field to hospital. Offline triage, prescriptions, and medical records.
Logistics Ops
Real-time inventory visibility across all nodes. Track supplies, medications, and equipment status.
What is a PWA?
A website that installs like an app. No app store needed — just visit and add to your home screen.
How Does It Work?
PWAs cache everything locally. Once installed, the app runs from your device, even without internet.
Why Does It Matter?
In disasters, networks fail first. PWAs keep working when you need them most — offline, reliable, instant.
Event Bus
Real-time cross-tab synchronization. When a nurse updates a patient status, doctors see it instantly.
Unified API
Standardized communication protocol with automatic retry, timeout handling, and error recovery.
Offline Queue
Operations continue seamlessly without internet. Data syncs automatically when connection returns.
