Abstract: A system and method are disclosed for identifying monitoring and evaluating hazardous or potentially hazardous conditions. The system may be worn by safety personnel to detect equipment conditions such as low power supply, environmental conditions such as ambient temperature and/or physiological conditions such as heart rate of a wearer. The system further includes a control unit having electronics operable to communicate signals associated with equipment, environmental and physiological conditions.

Abstract: A system and method are for alerting safety personnel of unsafe air temperature conditions. The system includes a temperature sensor exposed to the ambient environment, a temperature indicator disposed in a field of view of safety gear such as a face mask, and a control unit. The temperature indicator and the control unit may be disposed in a protected location, such as within the face mask. The control unit may produce warnings based on detected temperatures and exposure time thresholds. Detected temperatures may also be recorded, along with positioning information, such as GPS data, to facilitate mapping of temperature gradients. At startup, the system may automatically execute a battery check and produce a warning if insufficient charge remains to provide a predetermined operating time. Various embodiments may use an arm to keep the temperature indicator within the field of view or a single screw attachment to a face piece.

Abstract: A system and method are disclosed for alerting safety personnel of unsafe air temperature conditions. The system includes a temperature sensor formed to be exposed to an ambient environment and operable to provide a signal representing a measured ambient temperature. The system also includes electronics formed to be attached within protection provided by safety equipment. The electronics are coupled to receive the signal from the temperature sensor. The electronics are then operable to process the signal, to detect an unsafe temperature condition and to provide an indicator signal responsive to the unsafe temperature condition. The system further includes an indicator coupled to receive the indicator signal from the electronics. The indicator then responds to the indicator signal by providing a visible indication of the unsafe temperature condition.
