Anticipatory interactive protective system
First Claim
1. An interactive protective system to protect an individual from exposure to a dangerous condition, comprising a protective garment adapted to be worn by the individual, the protective garment including sensor means for sensing when the protective garment is being properly worn and signalling means responsive to the sensor means for actively generating a signal indicating that the protective garment is being properly worn, the system further comprising detector means responsive to the signal form the signalling means for detecting the signal, at least one sensor separate from the protective garment and responsive to positional change relative to the dangerous condition for arming an alarm, and control means responsive to the detector means for activating said armed alarm in the absence of detection of the signal.

Abstract
One or more sensors located on or surrounding a dangerous condition anticipate when an individual is approaching a hazard zone associated with the dangerous condition and then arms an alarm and activates an interactive protective system which protects an individual from exposure to the dangerous condition. The interactive system comprises a protective garment adapted to be worn by the individual. The protective garment includes a sensor for sensing when the protective garment is being worn and a signalling device responsive to the sensor for generating a signal indicating when the protective garment is being worn. A detector and control device responsive to the signal from the signalling device triggers an alarm sensible to the individual when it is activated by the motion sensor and does not sense the signal from the signalling device.

An interactive protective system to protect an individual from exposure to a dangerous condition, comprising a protective garment adapted to be worn by the individual, the protective garment including sensor means for sensing when the protective garment is being properly worn and signalling means responsive to the sensor means for actively generating a signal indicating that the protective garment is being properly worn, the system further comprising at least one sensor separate from the protective garment and responsive to positional change relative to the dangerous condition for arming an alarm and for activating a detection and control means, said detection and control means being responsive to the signal and operatively associated with the alarm for activating the armed alarm only when the detection and control means does not detect the presence of the signal.
- 19. An interactive protective system to protect an individual from exposure to a dangerous condition, comprising a protective garment adapted to be worn by the individual, the protective garment including sensor means for sensing when the protective garment is being properly worn, signalling means responsive to the sensor means for actively generating an electromagnetic signal indicating that the protective garment is being properly worn and means for modulating the signal at a modulation frequency selected to identify a specific protective garment which may be used in close proximity to other protective garments, the system further comprising at least one sensor separate from the protective garment and responsive to positional change relative to the dangerous condition for arming an alarm and for simultaneously activating a detection and control means, said detection and control means responsive to the modulated signal from the signalling means and operatively associated with the alarm for triggering the armed alarm only when the detection and control means does not detect the presence of the modulated signal, and means for preventing, for a preselected time delay, the detection and control means from triggering the armed alarm following interruption of detecting the signal.
- 23. An interactive protective system to protect an individual from exposure to a dangerous condition, comprising a protective garment adapted to be worn by the individual, the protective garment including sensor and proximity means for sensing when the protective garment is being properly worn in a proximity to the individual'"'"'s body which is consistent with proper employment of the garment, signalling means responsive to the sensor and proximity means for actively generating an electromagnetic signal indicating that the protective garment is being worn in a manner consistent with proper employment and means for modulating the signal at a modulation frequency selected to identify a specific protective garment, the system further comprising at least one directional motion sensor separate from the protective garment and responsive to positional change relative to the dangerous condition for arming an alarm and for simultaneously activating a detection and control means responsive to the modulated signal from the signalling means and operatively associated with the alarm for triggering the armed alarm only when the detection and control means does not detect the presence of the modulated signal, and means for preventing, for a preselected time delay, the detection and control means from triggering the armed alarm following interruption of detecting the signal.
