A system and method for controlling the cooling fan within an electronic display based on the amount of ambient light present. An ambient light sensor is used to measure the amount of ambient light which is contacting the display. To anticipate a temperature rise and lower the thermal inertia of the display, the fan speed is increased when high ambient light levels are measured at the exterior of the display. The ambient light sensor data may be used to apply a temperature correction factor to a temperature sensor within the display. Alternatively, the ambient light sensor data may be used to apply a fan speed correction factor to a desired fan speed (calculated based on a temperature sensor within the display). Multiple systems or methods can be used simultaneously within the display to cool several components which may heat and cool at different rates relative to one another. The various systems can have similar or different logic depending on the amount of cooling needed and the manner in which the cooled-components produce / absorb heat.

A device, applicator and a cosmetic non-therapeutic method of treating at least one area of the human body. The device includes a composition held in a container or a substrate and an applicator configured to apply the composition. The applicator includes an application surface that includes an application surface material with at least one of a thermal inertia of at least 1,000 Jm−2K−1s−1 / 2 and a thermal conductivity greater than or equal to 1 Wm−1K−1. The method includes providing an applicator, cooling the applicator to a temperature below or equal to 15° C., and loading the cooled applicator with a cosmetic composition at a temperature closer to an ambient temperature than that of the applicator, and applying the composition using the applicator, or before or after the cooling, applying a cosmetic composition, and after the cooling, bringing the cooled applicator into contact with the area to be treated.

The invention relates to a liquid cooling temperature thermostatic bath system and an intelligent temperature control method thereof, comprising a cooling water tank and a cooling liquid, a liquid bath and a working liquid, and an intelligent temperature controller. The cooling water tank is provided with a water tank temperature sensor and a refrigerator, an electrical heater connected with an electrical heating executor, and a water cooler, a stirrer, a liquid bath temperature sensor, and a water inlet pipe and a water outlet pipe of the water cooler that are connected with the cooling water tank; the other end of the water inlet pipe is connected with a cooling water pump, a signal input end of the intelligent temperature controller is respectively connected with the temperature sensor of the cooling water tank and the temperature sensor of the liquid bath, while the output end is respectively connected with the electrical heating executor, a stirrer engine, the cooling water pump and the refrigerator. The system and the method can drop the temperature at a speed higher than the natural cooling by near 20 times through forced liquid cooling, and can effectively avoid the over regulating of temperature and reduce the negative impact of thermal inertia, thus greatly shortening the precision temperature controlling process and cutting down power consumption.
