Refrigerating clothes may include a clothes body and a refrigerating mechanism having a working medium capable of changing between gas and liquid. The refrigerating mechanism includes a radiating surface and a refrigerating surface, between which the working medium circulates. The refrigerating surface is abutted against the clothes, and the radiating surface is arranged at one side far away from the refrigerating surface. The radiating surface absorbs thermal radiation from sunlight and provides energy for the working medium, the working medium absorbs heat on the refrigerating surface to realize cooling, and continuously circulates in the refrigerating mechanism without need for frequent replacement.

A self-contained functional and physical architecture is described to utilize a honeycomb configuration Positive Temperature Coefficient semiconductor thermistor heater to provide breathable warm air to an individual under cold weather conditions. The high-temperature of the heater element provides substantial efficiency allowing hours long use on battery power only. The invention utilizes pulsed heater operation in combination with lengthwise air mixing to rapidly and efficiently lower the temperature of the high temperature heated air to a temperature that is breathable. The invention solves issues with visor fogging, adaptability to a wide temperature range, and adaptability to a wide range of individual exertion. This system is applicable to a wide range of cold weather work environments, cold weather sports, scientific exploration, military operations, or medical needs. Several physical embodiments are described utilizing various forms of helmets and masks.

Operatives are monitored in a hazardous environment. A control unit is connected to a wiring loom embedded within an item of clothing having illuminatable devices and interface connectors. A monitoring device is connected to an interface connector and a radio device is connected to an interface connector. The control unit is activated to supply power to the connected monitoring device and the connected radio device. Condition data is conveyed from the monitoring device to the control unit. Uplink signals are transmitted from the control unit to a base station via a cellular radio communication module. Downlink signals are received at the control unit from the base station. Condition data is transmitted via the cellular radio communication module when the downlink signals are being received. Condition data is transferred to the non-cellular radio device when the downlink signals are not being received, for transmission to the base station.

An autonomous cooling vest to cool its user by evaporating a coolant in contact with the user's skin surface is described. Multifunctional panels attached to the vest in the parts corresponding to the human body are permeable to ambient air and contain a liquid retaining screen kept in contact with the user's skin. The cooling support system automatically controls the transfer of the coolant liquid contained in a reservoir to each screen and allows the user to adjust the operation of the system to activate and deactivate the ventilation on the liquid retained in the screens and adjust the amount of liquid dispersed over the screens as needed. The flow of air ventilated by the fans and the air that permeates through the referred multifunctional panels favor the evaporation of the liquid retained in the screens, promoting the user's cooling.
