Tokyo, Japan, October 5, 2022 - Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, Mitsui Fudosan Hotel Management Co., Ltd., and Tellus You Care, Inc. (“Tellus You Care’) hereby announce the introduction of Tellus, a monitoring device using millimeter-wave radar technology, at Mitsui Garden Hotel Kashiwa-no-ha Park Side, a hotel supporting cancer patients. Sales of accommodation plans with the Tellus option started from October 5. This is the first time that Tellus has made a full-scale introduction into a hotel.

Mitsui Garden Hotel Kashiwa-no-ha Park Side, which opened in July 2022, is located on the grounds of National Cancer Center Hospital East, which handles nearly 300,000 patients yearly, and provides a 24-hour supportive stay environment to patients and family members who accompany them. Going forward, the hotel will continuously devise accommodation plans that utilize advanced technologies or services from a variety of companies to enable patients and their families to use the facility with even further peace of mind. Tellus You Care will be the first company to introduce a service to the hotel since its opening with the introduction of Tellus, a monitoring device using advanced millimeter-wave radar technology that it developed and provides.

Tellus, is a health technology company, has created a monitoring device equipped with a sensor using millimeter-wave radar technology that detects sleep and activity patterns in a privacy-first manner. Unlike cameras, radars work by detecting movement and are unable to identify specific characteristics of people, such as if they are men or women, or what clothing they are wearing. By sensing the slightest of movements and combining this with advanced AI it is possible to determine activity conditions such as sleep, and a person’s vitals. Data is managed through the cloud platform and administrators can monitor it in real time. The hotel will initially only detect sleep and wake times, but from 2023 onward will move ahead on the detection of blind spots such as falls, crouching down or suchlike in washrooms or guestrooms. Any such incident will trigger a notification that is sent immediately to family members or care staff stationed in the hotel. The company aims to build a service that alleviates the anxiety of patients staying alone, and their families, and provides a safer and more secure accommodation environment.

To use the service, select the plan with the “Tellus’ option when making a reservation.

■Tellus Monitoring Sensor

Tellus was an early adopter of sensors using millimeter-wave radar technology used in automated driving and measures activity conditions in a contact-free manner that protects privacy. The palm-sized device emphasizes ease of use and installation, and can collect information on a person's sleeping, crouching down or other activities just by plugging it into an electrical outlet. By setting a shared destination for data, it can be viewed remotely by family members and notify regarding status. Tellus is being installed in facilities, mainly for the elderly, and this is the first initiative where it is being used in a hotel.
