Summer factories, construction sites, and logistics sites. "I thought it would be fine for now." This complacency is leading to an increase in serious accidents and withdrawals. In recent years, especially with the prolonged heat waves and the trend of revising labor safety and health regulations, companies are being urged to strengthen their measures against heatstroke. "Canary Plus" is a wristwatch-type wearable device that detects heatstroke risk based on changes in deep body temperature. An alarm sounds when the deep body temperature approaches 38°C, notifying you of the risk of heatstroke. Additionally, - No charging required (single-season use) - IP67 dustproof and waterproof - Lightweight design at approximately 30g - Easy-to-wear wristwatch type are features that make it user-friendly for on-site use. Demonstration tests have also been conducted with the Tokyo Fire Department, confirming the effectiveness of the algorithm in high-stress environments.

In the construction industry, there is a lot of outdoor work, creating an environment with a high risk of heatstroke. To maintain a safe working environment, it is important to manage the health of workers. In particular, in recent years, there has been a trend of prolonged extreme heat and revisions to labor safety and health regulations, leading to a demand for companies to strengthen their heatstroke countermeasures. "Canary Plus" is a wristwatch-type wearable device that detects the risk of heatstroke based on changes in core body temperature. An alarm sounds when the core body temperature approaches 38°C, notifying of the risk of heatstroke. 【Usage Scenarios】 - Managing heatstroke risk during work at construction sites - Compliance with mandatory heatstroke countermeasures - Strengthening safety measures on-site 【Benefits of Implementation】 - Reducing the risk of accidents due to heatstroke - Improving health management and safety for workers - Strengthening safety measures as a company

In the security industry, there is a high risk of heatstroke due to long hours of outdoor work and operations in high-temperature environments during the summer. Particularly in patrol and monitoring tasks, it can be difficult to notice changes in physical condition, which may lead to worsening situations. Accidents caused by heatstroke can result in delays in operations and staff shortages, potentially damaging the company's reputation. "Canary Plus" supports the health management of security personnel by estimating changes in core body temperature and notifying them of heatstroke risks through alerts. 【Usage Scenarios】 - Outdoor patrol duties - Summer event security - Long-duration monitoring tasks 【Benefits of Implementation】 - Prevention of accidents due to heatstroke - Strengthening of workers' health management - Maintenance of operational efficiency

In the delivery industry, tasks such as loading and unloading packages in the scorching sun and long-distance driving are essential in environments with a high risk of heatstroke. Managing the health of workers is crucial for maintaining operational efficiency and ensuring a safe working environment. Heatstroke can lead to decreased performance among workers and potentially serious accidents. "Canary Plus" supports the health management of workers by estimating changes in core body temperature and notifying them of heatstroke risks through alerts. 【Usage Scenarios】 - Loading and unloading tasks in the scorching sun - Long-distance truck driving - Outdoor delivery operations 【Benefits of Implementation】 - Reduction in the number of workers suffering from heat-related illnesses - Increased safety awareness among workers - Stabilization of working hours

In warehouses and logistics sites, the safety management of workers is becoming increasingly important. In particular, warehouses tend to become high-temperature environments during the summer, leading to significant issues such as heat-related illnesses, decreased work efficiency, and increased accident risks. There are not a few cases where thinking "I'm still okay" can lead to major troubles. "Canary Plus" is a wearable device that estimates changes in core body temperature and alerts users to the risk of heat-related illnesses. It notifies dangers through sound, supporting heat illness prevention measures that do not rely solely on the workers' own awareness.

【Fan-assisted airflow + Peltier cooling plate】 Due to the recent extreme heat, there has been an increase in feedback that "the air comes in, but it's not cool" with typical cooling clothing. Therefore, we have developed a dual cooling fan equipped with a cooling plate. 【Double cooling sensation from fan airflow and cooling plate】 STEP 1: The air blown from the fan evaporates sweat, lowering body temperature through evaporative cooling. STEP 2: The cooling plate lowers the temperature of the air circulating inside the clothing, enhancing the cooling effect. STEP 3: The cooling plate directly contacts the body, allowing you to feel the coolness instantly.

In the construction industry, work is often required in harsh environments, such as long hours outdoors or near heat sources. In such situations, workers' body temperatures can rise significantly, increasing the risk of heatstroke. There are growing concerns that general cooling vests may provide airflow but not sufficient cooling. Therefore, the W cooling fan equipped with a cooling plate enhances worker comfort and strengthens heatstroke prevention through a dual cooling effect of airflow and the cooling plate. 【Usage Scenarios】 - High-altitude work outdoors - Work near heat sources - Long hours of heavy machinery operation - Material transportation during summer 【Benefits of Implementation】 - Suppression of workers' body temperature rise - Reduction of heatstroke risk - Improved work efficiency through sustained concentration - Fatigue reduction

In the manufacturing industry, temperature management in the work environment significantly affects product quality maintenance. In particular, working in high temperatures can lead to decreased concentration and health issues, increasing the risk of defective products. Therefore, it is important to maintain worker comfort and ensure stable quality. Our W Cooling Fan contributes to quality maintenance by suppressing temperature rise in the work environment through a combination of fan airflow and double cooling plates. 【Usage Scenarios】 - Work in factories with high temperatures - Precision tasks that require quality control - Long hours of outdoor work 【Benefits of Implementation】 - Reduction in perceived temperature for workers - Improved quality due to maintained concentration - Decreased risk of heat-related illnesses
