Wandering Prevention · Duress & Fall Alerts · Night Rounds — RTLS for Long-Term Care

Long-Term Care Resident Safety & Asset Tracking System

Q: Long-term care facilities have many partitions and walls — will they block the positioning signal and cause errors?

P-Square uses its patented AI Fingerprinting (RF Fingerprinting) technology. Compared with conventional trilateration, accuracy and partition-level correctness improve by more than 30% in multi-obstacle, heavily partitioned environments, reliably confirming which room or corridor a resident is in.

P-Square combines fixed wireless positioning with a mobile AI guidance robot to give residential aged-care facilities a single integrated safety net: wandering prevention with geofencing, one-touch duress and fall detection, wheelchair and medical asset tracking, automated night rounds, and dual-camera AI rehabilitation exercise. The proprietary AI Fingerprinting algorithm improves partition-level accuracy by over 30% versus conventional trilateration, and label tags run for up to a year on a single battery.

Pain Points and Solutions

Pain Point	Description	Solution
Sudden illness or falls with no way to call for help	When a resident falls or becomes unwell in their room or a corridor, they often cannot reach the bedside call button, and the golden window for intervention is lost.	A wearable tag with an SOS duress button and posture / fall sensing transmits precise coordinates immediately, accelerating the emergency response.
Residents with dementia wandering or entering hazardous areas	Residents with dementia may leave their zone unnoticed or enter kitchens and plant rooms, while conventional door locks compromise dignity and freedom of movement.	Geofences push an automatic alert as a resident approaches a controlled exit, balancing freedom with safety.
Night rounds stretch already thin staffing	Night shifts run on minimal staffing, yet carers must walk room to room repeatedly — a heavy physical and psychological burden over time.	A mobile AI robot with SLAM LiDAR navigation patrols corridors automatically overnight and reports anomalies immediately.
Wheelchairs, mobility aids and medical devices cannot be found	Wheelchairs, oxygen concentrators and monitoring equipment are borrowed across zones or left anywhere; searching at handover wastes time and degrades care.	BLE asset tags let staff locate equipment instantly from the web console and floor plan.

System Applications

Wandering Prevention

Wearable BLE tags with zone geofences alert the nursing station the moment a resident approaches an exit or hazardous area.

Duress & Fall Alerts

Pressing the portable SOS button, or a sudden abnormal posture change, surfaces precise coordinates with floor and room on the nursing station screen.

Asset Tracking

Live coordinates for wheelchairs, oxygen cylinders and nursing trolleys, improving cross-zone redeployment and reducing loss.

AI Night Rounds

Scheduled overnight patrols, generative-AI conversational companionship, text communication for hearing-impaired residents and remote nursing video consultation.

AI Rehabilitation

Front and side AI skeletal keypoint recognition guides residents through engaging stretching exercises to maintain mobility.

Solution Modules

Module	Technology & Hardware	Trigger / Mechanism	Care Value
Resident safety & wandering prevention	BLE Locator + wristband tag (PTG_002)	Geofence alerts on approaching a controlled exit or leaving a zone without authorisation	Automatic push to the nursing station, reducing wandering risk while preserving freedom of movement
Duress & fall reporting	Button tag + immobility / posture sensing	Resident presses the SOS button, or prolonged immobility or a fall is detected	Precise coordinates appear on the nursing station map, accelerating emergency response
Equipment & wheelchair tracking	BLE asset tag (PTG_001) + web console	Search the floor plan for wheelchairs, diagnostic equipment or nursing trolleys	Cuts equipment search time, reducing handover burden and operating cost
AI guidance robot	LiDAR SLAM + UWB / RGBD relative positioning	Automated overnight rounds, generative-AI conversation and video calling	Replaces scheduled walk-rounds, eases resident isolation and lightens the night-shift workload
Dual-camera AI rehabilitation	AI Box + front and side cameras for skeletal recognition	Detects wrist and skeletal keypoints to guide stretching and activation exercises	Engaging interaction that helps residents correct posture and maintain upper-limb mobility

Deployments and Field Collaboration

Validated in Hospitals and Long-Term Care Facilities

P-Square's technology has been validated in real-world deployments across a number of healthcare providers and long-term care institutions in Taiwan.

In partnership with National Yang Ming Chiao Tung University: a demonstration site at a well-known care facility in northern Taiwan, running a mobile AI guidance robot for smart patrolling and resident interaction services.
Clinical duress and equipment tracking: successfully deployed at a Ministry of Health and Welfare hospital in Taipei, Taipei Veterans General Hospital Fenglin Branch (clinical duress system), Cheng Hsin General Hospital (operating-theatre equipment tracking) and China Medical University Hsinchu Hospital (AI robot guidance and communication support for hearing-impaired and elderly users).
Social impact: selected for the Social Innovation Top 100 with an award for innovative communications value, working with the Hsinchu County Senior Citizens Association and the Hsinchu City Physically Disabled Self-Reliance Association to refine the user experience.

Technical advantages: partition-level accuracy improved by over 30% through the proprietary AI Fingerprinting algorithm; each P-Square Locator drives four Bluetooth read heads (1-to-5 deployment), cutting hardware volume to roughly a fifth and saving cabling cost; BLE 5.0 label tags (PTG_001) run for up to a year and wristband tags (PTG_002) for about four months. A standard RESTful API and iframe integration connect seamlessly to existing facility systems.

Frequently Asked Questions

Long-term care facilities have many partitions and walls — will they block the positioning signal and cause errors?

P-Square uses its patented AI Fingerprinting (RF Fingerprinting) technology. Compared with conventional trilateration, accuracy and partition-level correctness improve by more than 30% in multi-obstacle, heavily partitioned environments, reliably confirming which room or corridor a resident is in.

How long does the tracking wristband battery last? Does it need frequent charging?

No daily charging is needed. At one advertisement per second, the PTG_001 label tag with a CR2477 cell lasts about a year and the PTG_002 wristband with a CR2032 about four months. The advertising interval is adjustable between 100 ms and 5000 ms, and lengthening it extends runtime. The system reports low battery, so tags do not have to be checked one by one.

How does the AI guidance robot support night-time care?

The mobile AI robot combines LiDAR with autonomous obstacle-avoidance navigation to patrol corridors and rooms on a schedule overnight. If a resident leaves their bed or room unexpectedly, it notifies the duty carer immediately, materially reducing the night-shift burden.

Will installation damage existing interiors or require expensive construction work?

No. P-Square Locators are compact and can be installed flexibly under raised flooring or inside suspended ceilings without affecting the appearance of the facility. In addition, one Locator can drive four read heads, cutting equipment volume to roughly a fifth and significantly reducing both installation and hardware cost.
