Smart Care & Assisted Living

Three boundaries that matter most in care settings

WHAT GOES WRONG TODAY

Privacy concerns with cameras

Bedrooms and bathrooms are hard to cover with cameras, and residents and families generally resist continuous recording.

Anomalies found only by manual patrols

Care staff are limited; scheduled room checks consume many hours and prolonged inactivity is often only noticed at meal delivery or rounds.

Devices that do not speak the same language

Calls, access, energy and inspections sit in separate systems with no unified activity view or tiered reminder rules.

Three-layer architecture: sensing → gateway → platform

SYSTEM ARCHITECTURE

Three-layer architecture: battery-free sensing, EnOcean gateways, the unified IoT platform, PC console, device app and business mini-program

Sensing layer · non-visual

mmWave presence, PIR, door/window contacts, water leak and self-powered buttons — no image capture

Network layer · multi-mode gateway

EnOcean 868 MHz aggregates battery-free points; a multi-mode IoT gateway handles backhaul, with room-level administration

Platform layer · private deployment

Care dashboards, activity patterns, tiered reminders and care records, with rules per facility / floor / room

Six functions, protecting privacy and response

WHAT YOU GET

Non-Visual Activity Patterns

Presence and door-contact state describe daily routines in a daily activity overview, with no image data generated.

Prolonged inactivity alerts

Set an observation window per room; exceeding it with no activity change triggers a reminder for caregiver review.

Optional fall risk assessment

LD-OSR mmWave sensors detect stationary occupants and offer optional fall detection for higher-risk rooms.

Night-time door/window and bed-exit anomalies

Door contacts report opening/closing outside set hours, or night activity that deviates clearly from the routine, for duty-staff review.

One-touch bedside call

LD-CC self-powered buttons mount at bedsides and in bathrooms without wiring; each press is kinetically powered and reaches the care terminal directly.

Tiered reminders & care records

Reminders are routed by severity to floor duty staff and nursing stations; review and handling are logged into a traceable care record.

Typical BOM (one care unit)

TYPICAL BILL OF MATERIALS

LD-OSRmmWave presence sensor · 24–24.25 GHz · stationary occupant detection · optional fall detection

LD-OSPPresence sensor · non-contact temperature · stationary occupant detection

LD-MCBattery-free wireless door/window contact · indoor light powered · state and event counts

LD-CCBattery-free wireless button · SOS call · kinetic powered · Ø46 mm

LD-FSElectrode water leak sensor · standing water alerts in bathrooms and wash areas

Multi-mode IoT gatewayMulti-protocol aggregation and uplink · one per care unit · model confirmed per project

Typical configuration only. Observation windows, alert levels and review workflows are set by the operator's service standards; system output supports but does not replace on-site caregiver judgement.

What changes in care after rollout

PRIVACY

Data yes, cameras no

Presence and door/window events describe activity patterns without cameras in bedrooms or bathrooms, easing concerns for residents and families.

NURSING

Focus limited patrol staff on higher-risk rooms

Prolonged inactivity and night anomalies are flagged by the system and reviewed by staff; patrol schedules can be prioritised from the activity overview.

Start with one care unit, then scale to the floor
