ASTRI, in partnership with two other HKSAR Government-subvented R&D centres, developed a tracking and monitoring system that protects vulnerable groups like the elderly. The system, which has been applied in 11 elderly day care centres of the Tung Wah Group of Hospitals (TWGH), has been chosen as the “Best Smart Care Technology Solution” at the 6th Asia Pacific Eldercare Innovation Awards. The award ceremony was recently held in Singapore.
TWGH, the end-user of the system, had nominated this “Installation of anti-wandering system for Day Care Centre for the Elderly” solution for this award. The system which works simultaneously through built-in RFID, GPS and BLE trackers. It greatly reduces the risk of vulnerable senior citizens being missing from elderly homes or other care centres. In addition to making life less stressful for the caregivers, the system also facilitates the improvement of elderly-caregiver ratio and overall service quality. Most importantly, it allows the elderly to be more involved in outdoor activities without the risk of getting lost.
The project has been a collaborative effort of three Government-subvented institutions: Hong Kong Applied Science and Technology Research Institute (ASTRI), Hong Kong Logistics and Supply Chain MultiTech R&D Centre (LSCM) and Hong Kong Research Institute of Textiles and Apparel (HKRITA). These quangos, bringing together their collective strength and expertise, developed a tracking system to improve elderly-care. While LSCM contributed the RFID and GPS tracking system, HKRITA designed a special vest which houses the RFID tracker, GPS tracker and the BLE (Bluetooth Low Energy) device hardware. ASTRI provided the proximity monitoring system through BLE, responsible for the whole system integration, hosting the main server. ASTRI also conducted the system’s trial at TWGH facilities and Wong Chung Tong Day Care Centre for the Elderly.
The ‘6th Asia Pacific Eldercare Innovation Awards’ is widely revered as the ‘Oscar for the Eldercare sector’ in the Asia-Pacific region. This year, the award nominees and participants represented 19 countries and territories from across the region.
ASTRI has worked with the healthcare industry to develop a low-cost, handheld, connected Upper Gastrointestinal Endoscope. With its high definition disposable camera design, the device can stream real-time video to large displays, helping the process of diagnosis with no need for complicated sterilisation.

ASTRI is developing an image analytics platform for digital pathology. It is based on a scalable medical image database, distributed parallel computing engine, and a powerful application development environment for Computer-Aided Diagnosis (CAD). The platform can support efficient management of medical image data. It also facilitates reliable web-based digital pathological information exchanged in telediagnosis and agile development of CAD applications.

ASTRI has established a family of low power ADC IPs.
12/14 bit low power Successive Approximation Register (SAR) ADC delivers low power and low cost analog to digital conversion of reasonable performance for portable medical and sensor devices. ASTRI’s IP is already in mass production for various applications.
24-bit sigma delta ADC is based on sigma delta technology intended primarily for instrumentation applications. It consists of a second-order three-bit quantizer noise shaping modulator and digital decimation filter.
Low input-referred noise: 1.5uVrms
Multi-bit feedback DAC with Data-Weighted Averaging to achieve low power consumption
Unity feedforward architecture for low distortion
2nd order modulator loop, stable for full scale input
ASTRI’s uncooled infrared micro-bolometer readout IC is a high resolution, low power consumption and low noise signal sensing IC for deployment in thermograph applications, such as night vision, surveillance and medical imaging, which require high resolution imaging capability.
640 x 480 pixel focal plan array
Pixel pitch = 20um x 20um
Uncooled operation (with or without thermo-electric cooler)
Adjustable integration time
Adjustable integration capacitors
2 analog outputs available
Digital selection mode via SPI
Power consumption < 360mW (without thermo-electric cooler)
A device to facilitate early detection and screening of elderly with cognitive health problems and also assessing the stress level of general public is being developed. This device can be used for early detection and continual monitoring of cognitive impairment, as well as to improve the experience and ease of cognitive assessment for the elderly in Hong Kong.
