We have published two application pages for the non-contact, camera-less monitoring sensor "MotionCatch." You can view them from the related products section below. 【Published Pages】 - MotionCatch | Non-contact monitoring sensor for public facilities SE - MotionCatch | Smart home monitoring sensor SE 【Features of MotionCatch】 - Detects human movement non-contact using millimeter-wave radar and AI. - No cameras used and no video recording. Provides monitoring with consideration for privacy. - Palm-sized. Simply install on walls or ceilings without the need for wiring (USB powered, Wi-Fi). - The detection range of one unit is approximately 6m x 4m. It is suitable for monitoring "by room" rather than the entire floor. We are accepting inquiries regarding installation conditions and trial implementations (PoC). *No video is recorded. This is a product designed to assist monitoring and is not a medical device.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can cause changes in 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 with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

In civil engineering projects such as parks, rivers, mountainous areas, and tourist sites, selecting temporary materials that consider the surrounding landscape is important in addition to safety and workability. Metal steel plates are practical, but they can stand out in natural environments and may not blend well with the landscape. Hyper CLT sheets are civil engineering CLT materials that utilize laminated timber. They have the natural color and texture of wood, allowing for the creation of temporary roads, access routes, heavy machinery work yards, material storage areas, and worker pathways that harmonize with the surrounding environment. They can also be used as an alternative to steel plates for mud prevention and ground protection. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce the burden of installation and removal. They also have environmental features unique to wood, such as glare reduction, noise suppression, and CO2 fixation. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS "TH-250021-A," these wooden sheets can be utilized for landscape consideration, creativity, and improving the image of public works projects.

In civil engineering sites, workers stand for long periods and move around the site multiple times. Muddy and uneven ground makes walking difficult, leading to strain on the feet and back, as well as an increased risk of falls, so ensuring a stable work path is important. Hyper CLT mats are civil engineering CLT materials that utilize laminated CLT wood. By laying them down in areas such as temporary roads, material storage sites, assembly areas, break areas, and worker pathways, they help reduce unevenness and mud, creating a more walkable environment. They possess surface characteristics unique to wood, providing a walking environment that differs from metal plates. The 5×10 panel weighs about 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which helps reduce the burden of installation and removal. Additionally, they can be used to address environmental concerns such as glare reduction, noise reduction, and CO2 fixation, as well as measures against heatstroke. They are recommended for creating worker-friendly sites and innovative public works as a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A."
