Early detection of heatstroke risk! We support workers' health management with a dedicated wristband!

【NETIS Registration Number】KT-240128-A "GenVital LTE" is a system that supports the health management of field workers by instantly notifying both the work manager and the worker themselves with an alert when indicators calculated by the health management judgment algorithm developed by Obayashi Corporation exceed set thresholds. These indicators are based on heart rate and location data collected through a wristband, as well as the heat index at the construction site. <Standard features specialized for the health management of field workers> ⚫︎ Four-level indicator display ⚫︎ Fall detection ⚫︎ SOS signal from the wearer ⚫︎ Location data acquisition ⚫︎ Automatic collection of heart rate and heat index ⚫︎ Daily/Monthly report output With the revision of the Labor Safety and Health Regulations coming into effect on June 1, 2025, businesses will be required to implement measures against heatstroke. The use of wearable devices is also recommended to quickly identify workers at risk of heatstroke. "GenVital LTE" is a device that quickly detects the risk of heatstroke and is suitable for the safety management of field workers! Please feel free to consult with us.

• Analysis and prediction system

A booklet with case studies as a gift! Introducing points to prevent heatstroke and sudden health changes in advance!

In this case study, we interviewed Obayashi Corporation and Sankyu Inc., leaders in the construction and logistics industries, to introduce their specific initiatives for "early detection of heat stroke risks" and "ensuring the safety of workers." Additionally, we have published an interview article with Obayashi Corporation, who contributed to the development of "GenVital LTE," as a "development story." As the risk of heat stroke has become a social issue, we encourage everyone working to improve on-site productivity and safety measures for workers to read this as a source of inspiration. GRIFFY will continue to contribute to creating safer and more comfortable work environments through DX solutions, including "GenVital LTE." ◾️ Obayashi Corporation (case study) ◾️ Sankyu Inc.

We are pleased to announce that Gywood has been recommended as a featured building material in the special project "Recommended Building Materials" at the Housing Business Fair within the comprehensive exhibition for housing, architecture, and real estate [BREX Kansai]. We will be exhibiting in the "Recommended Building Materials and Equipment" zone, where professionals from the field gather to showcase their recommended materials. We invite everyone to stop by and visit us.

Seminar Overview As the labor shortage in manufacturing sites becomes more severe, the labor costs and time losses associated with the "transportation" of products and components, as well as "cleaning" within factories, have become critical management issues that cannot be overlooked. In this webinar, we will introduce the latest use cases of "Autonomous Mobile Robots (AMR)" and "Commercial Cleaning Robots" that achieve productivity improvements in manufacturing environments. We will specifically address questions such as "How are other companies operating these technologies?" and "What kind of cost reduction effects can be expected after implementation?" by providing concrete explanations of actual before-and-after scenarios and operational flows. Factory managers and members of production technology and DX promotion departments who want to advance automation and efficiency on-site are encouraged to participate! Recommended for: - Those who are unsure about where to start with automation, labor reduction, and DX in their factories. - Those who want to alleviate labor shortages on-site and focus resources on core operations to improve productivity. - Those who want to stay updated on the latest trends in the use of transportation robots (AMR) and cleaning robots.
