Abstract
A safety indicator monitors environment conditions detrimental to humans e.g., hazardous gases, air pollutants, low oxygen, radiation levels of EMF or RF and microwave, temperature, humidity and air pressure retaining a three month history to upload to a PC via infra red data interface or phone link. Contaminants are analyzed and compared to stored profiles to determine its classification and notify user of an adversity by stored voice messages from, via alarm tones and associated flashing LED, via vibrator for silent operation or via LCD. Environmental radiation sources are monitored and auto-scaled. Instantaneous radiation exposure level and exposure duration data are stored for later readout as a detector and dosimeter. Scans for EMF allow detection with auto scaling of radiation levels and exposure durations are stored for subsequent readout. Electronic bugs can be found with a high sensitivity EMF range setting. Ambient temperature measurements or humidity and barometric pressure can be made over time to predict weather changes. A PCS RF link provides wireless remote communications in a first responder military use by upload of alarm conditions, field measurements and with download of command instructions. The link supports reception of telemetry data for real time remote monitoring of personnel via the wrist band for blood pressure, temperature, pulse rate and blood oxygen levels are transmitted. Commercial uses include remote environmental data collection and employee assignment tasking. GPS locates personnel and reporting coordinates associated with alarm occurrences and associated environmental measurements.
