Physical condition or environmental threat detection appliance system

A device having a unique identification and for providing information about a physical condition and an environmental condition, the device comprising:

• a first sensor physically associated with a user for detecting predetermined environmental hazards;
• a second sensor physically associated with a user for detecting a physical condition as a biological or chemical change in the user;
• means associated with the sensors for notifying the user or a third party of the detection of the environmental hazard or physical condition exceeding a predefined limit;
• means for conveying the unique identification of the device and information obtained from the sensors to the third party.

A system for providing information about a physical condition and an environmental hazard, comprising:

• a device being worn by a user and assigned a unique identification;
• a first sensor physically associated with the device for detecting the environmental hazard;
• a second sensor physically associated with the device for detecting a physical condition of the user;
• a remote receiver communicating with the device;
• means for conveying the unique identification of the device and information obtained from the sensors to the remote receiver;
• and
• means associated with the sensors for notifying the user or the remote receiver of the detection of the environmental hazard and/or physical condition exceeding a predefined limit.

A system for providing information about a physical condition and an environmental hazard, comprising:

• a device being worn by a user and assigned a unique identification;
• a first sensor physically associated with the device for detecting the environmental hazard;
• a second sensor physically associated with the device for detecting a physical condition of the user in the form of biological or chemical changes in the user;
• a remote receiver communicating with the device;
• an electronic circuit operably connected to the sensors and having a passive transmitter for conveying the unique identification of the device and information obtained from the sensors to the remote receiver;
• and
• an alarm for notifying the user or the remote receiver of the detection of an environmental hazard or physical condition exceeding a predefined limit.

A method for monitoring physical and environmental conditions of users in a potentially hazardous environment, comprising the steps of:

• assigning each user a device having a unique identification, a first sensor for detecting environmental conditions around the user, and a second sensor for detecting physical conditions of the user;
• logging each identification into a database;
• detecting a predetermined hazard using either the first or second sensor of one or more of the devices;
• conveying the unique identification and sensor information from the one or more devices to a receiver;
• identifying the one or more devices detecting the predetermined hazard;
• and
• notifying the one or more users of the identified devices of the detection of the predetermined hazard.

A method for monitoring physical and environmental conditions of users in a potentially hazardous environment, comprising the steps of:

• attaching a device to each user, the device having a unique pre-assigned identification, a first sensor for detecting environmental conditions around the user, and a second sensor for detecting physical conditions of the user;
• logging each identification into a database;
• detecting a predetermined hazard using either the first or second sensor of one or more of the devices;
• transmitting the unique identification and sensor information from the one or more devices to a receiver;
• identifying the one or more devices detecting the predetermined hazard;
• determining if the detected predetermined hazard exceeds a predefined limit;
• notifying the one or more users of the identified devices of the detection of the predetermined hazard exceeding the predefined limit.
