A smart alarm system determines when fire, carbon monoxide, or both are present in a specific area and responds accordingly. If fire is detected, alarms are activated, emergency services are notified, and ventilation, namely vents and fans, is cut off in the specific area where the hazard is detected. If carbon monoxide is detected, alarms are activated, emergency services are notified, and ventilation is increased by opening vents and activating exhaust fans to dissipate the gas from the area containing the gas. In the event both are detected, the system will keep the ventilation cut off to prevent the spread of fire.

When a fire accident takes place in the electronic equipment and the flame will run outward via said ventilation holes, the coated thermal expanding paint is thermally expanded to close said ventilation holes.

Disclosed are an apparatus, system, and method for endotracheal tube placement that allow for ventilation of the patient throughout the process of placing an endotracheal tube. The apparatus includes a T-shaped adaptor having a first lumen for coaxial connection to an artificial airway and a second lumen that intersects the first lumen for connection to a ventilator. A cap is provided over the distal end of the first lumen, the cap having an opening that may be closed with a flexible plug, blocking air from exiting through the first lumen when the second lumen is attached to a ventilator. The opening is sized to receive a fiber optic bronchoscope and to flexibly seal against the exterior of the fiber optic bronchoscope as it passes through the cap. A line of weakening extends from the opening to the perimeter of the cap, such that after the fiber optic bronchoscope has been advanced to the patient's trachea, the endotracheal tube may be advanced toward the cap, the cap may be split along the line of weakening to allow its removal from both the T-shaped adaptor and the fiber optic bronchoscope, and the endotracheal tube may be advanced over the fiber optic bronchoscope through the first lumen and the supraglottic airway without removal of the T-shaped adaptor, and thus while maintaining ventilation that is supplied through the second lumen of such T-shaped adaptor.

The invention belongs to the technical field of edible fungus production, and specifically relates to a method for cultivating wood ear. By using mother strain activating liquid containing antibiotics, antibiotics can inhibit the growth of bacteria under the condition of maintaining ventilation, but can not inhibit the growth of wood ear fungi, which can solve the problem that during an activationprocess of wood ear planting mother strains, the fungi can not be activated or the degree of activation is not enough to meet the requirement of inoculation due to bacterial contamination, the fruiting process can be completed within 10-15 days by using the temperature difference of 13-15 DEG C produced during the day and night and a light intensity of 2700-4000 Lx, compared with the traditional25-30 days, the fruiting time is saved, and the yield of the wood ear is higher, the cultivation bags are exposed in sun for 7-10 days after fruiting accelerating, the yellow water and mildly infectedmildew produced before fruiting accelerating due to temperature discomfort or excessive humidity can be sun-removed to prevent and control mildew from causing infectious infections, and the cultivation bags can grow new ears, thus improving the yield and quality of the wood ear.
