Utilizing terrestrial digital broadcasting and NerveNet etc. which are technologies
originating from Japan, we expect to help solving those problems.
We are planning to investigate the feasibility of an early warning system using NerveNet.
We are looking for partners to do research with us about application of this technology.

Example 2： Infrastructure system to observe the care recipient
In some ASEAN countries, rapid declining birth rate and aging population are proceeding
like Japan. There is a need for a mechanism to safely and efficiently capture the carerecipients in a hospital, home, and surrounding areas.
A Japanese company has plan to demonstrate such a system for care recipient incollaboration with multiple hospitals in Thailand, where NerveNet will be used.
