We would like to introduce MotionCatch as a monitoring sensor that can be used to understand office occupancy. Using millimeter-wave radar and AI, it non-contactly detects human movement and occupancy status. Since it does not use a camera and does not record images, it can be considered for installation in places where cameras are difficult to place, such as conference rooms, private rooms, and work areas. 【Suitable for the following situations】 - Understanding whether conference rooms are actually in use - Monitoring occupancy and absence in private rooms and work areas - Checking if absences are prolonged It can be installed on walls or ceilings and has a design that easily blends into existing spaces. Product materials and a comparison table of monitoring sensors can be downloaded from the related catalog below. We also welcome inquiries regarding the conditions for rooms where installation is possible and the number of units, so please feel free to contact us.

One of the major strengths of the Hyper CLT sheet is that it is a technology registered with the Ministry of Land, Infrastructure, Transport and Tourism's NETIS. The NETIS registration number is **"TH-250021-A."** In public works, it is important to explain to the client "why we are introducing it" and "what effects we expect" when adopting new materials. If it is a NETIS registered technology, it becomes easier to connect it to proposals for the utilization of new technologies and creative ideas. The Hyper CLT sheet is a civil engineering sheet that utilizes wood CLT. It is lightweight and easy to install and remove, and it has characteristics unique to wood, such as reducing summer heat reflection and noise, and fixing CO2. It is important to be able to propose it not just as "wooden sheets," but as a civil engineering technology registered with NETIS. The Hyper CLT sheet, which combines wood, NETIS, civil engineering, and CLT, is a new temporary material that makes it easier to clearly demonstrate the reasons for its introduction in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

The applications of Hyper CLT sheets are not limited to specific locations. Essentially, many civil engineering sites that have previously used steel plates are candidates for consideration. Wood CLT can be utilized in various places such as temporary roads, access routes, heavy machinery work yards, material yards, storage areas, temporary parking lots, and worker pathways. Of course, there are cases where steel plates are more suitable depending on site conditions, such as in areas with heavy loads or where heavy machinery needs to turn. The important thing is not to replace everything, but to use them appropriately according to the ground conditions, machinery, and intended use. Hyper CLT sheets are lightweight, easy to install and remove, and have unique characteristics of wood, such as reducing glare and metallic sounds, and fixing CO2. Furthermore, it is a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A."** By utilizing wood, NETIS, civil engineering, and CLT, it provides a new option for places that have previously used steel plates.
