Integrated physiologic sensor system
First Claim
1. A sensor system, comprisingheadgear comprising a headband;
- a first sensor attached to said headband wherein said first sensor detects an amount of carbon monoxide in a user'"'"'s blood when wearing said headband and produces a first data signal indicative thereof;
a second sensor attached to said headband wherein said second sensor detects an amount of oxygen in the user'"'"'s blood when wearing said headband and produces a second data signal indicative thereof;
a processor connected to said first and second sensors and attached to said headband wherein said processor receives the first and second data signals from said first and second sensors, respectively, and creates at least one condition signal indicating a hazard condition, wherein the condition signal is derived from at least one of the first and second data signals, a position sensor system connected to said headband, said position sensor system comprising;
a light source that emits a beam of light upon receiving a source signal from said processor; and
a light detector that detects the light emitted from said light source after the light reflects off an object, said light detector producing a detector signal for said processor, said processor calculating the distance between said object and said headband.

Abstract
An embodiment of the present invention comprises a self-contained breathing apparatus (SCBA) mask that incorporates a series of physiologic sensors. These physiologic sensors are mounted on the interior of the SCBA mask in such a way as to contact the facial skin of an individual wearing the mask. The physiologic sensors monitor, among other things, heart rate and carbon monoxide and oxygen saturation levels. The physiologic sensors are connected to a transmitting apparatus attached to the SCBA. The SCBA transmitter sends output data from the physiologic sensors to a remote processor. The SCBA transmitter also sends location information of the individual wearing the SCBA mask to the remote processor. The remote processor compiles the physiologic and location data for the wearer of the SCBA and transmits a signal back to the SCBA receiver which, in turn, sends a signal to a display integrated into a SCBA mask. The display indicates to the individual his physiologic status. The display incorporates indicator lights are integrated into the mask of the SCBA to indicate, for example, when bottled air must be switched on, to indicate the emergency situation of the wearer and/or to indicate the direction that the wearer of the SCBA is going. The processor associated with the transmitter also monitors groups of individuals wearing the SCBA masks. In this way, the particular status of several individuals in hazardous environment can be monitored at once and their situation known over a period of time in the hazardous conditions. Specifically, the physiologic condition of the group can be monitored to track the changes in the group condition over the time that the group is exposed to the hazardous environment.
