Wearable chemical threat detector
First Claim
1. A method for detecting airborne chemicals, comprising:
- (a) utilizing multiple wearable chemical detectors in a single general area;
(b) acquiring an environmental air sample within each wearable chemical detector;
(c) detecting that at least one chemical from a selected set of possible chemicals is present within the environmental air sample;
(d) analyzing data relating to the detecting;
(e) determining at least one of a chemical name, a chemical concentration, a chemical category, or a toxicity level;
(f) transmitting the determined information to a central data collection site;
(g) each wearable chemical detector communicating with each other information relating to chemical concentrations measured to generate an instruction; and
(h) receiving the instruction by at least one wearable chemical detector for a user to follow, wherein the instruction includes an indication of whether an alert from an alert mechanism on the at least one wearable chemical detector of one or more detected chemicals present is a false positive.

Abstract
The present disclosure generally relates to chemical threat detection, and more specifically, to a wearable chemical threat detector for an indoor or outdoor environment. In one embodiment, a method for chemical sensing and detection is disclosed. The method includes (a) deploying a plurality of wearable chemical detectors, (b) receiving an environmental air sample by at least one of the plurality of wearable chemical detectors, (c) receiving an alert of one or more chemical(s) present within the environmental air sample from at least one wearable chemical detector, (d) analyzing the alert for data relating to at least one of a chemical name, a chemical concentration, a chemical category, or a toxicity level, and (e) transmitting the data to a central data collection site. Furthermore, the embodiments disclosed may provide a warning and/or an evacuation route to a user once a threat is detected.

9. A wearable airborne chemical detecting system, comprising:
-
a housing; a gas sampling chamber disposed within the housing; a sensor operatively connected to the gas sampling chamber; a power management system disposed within the housing and operatively connected to the sensor; and a controller operatively connected to the sensor, comprising; a processor; and a memory integrated circuit (IC) storing instructions that, when executed by the processor, cause the system to; acquire an environmental air sample within the gas sampling chamber; electronically monitor the sensor for changes in resistance; detect via the electronic monitoring that at least one chemical of a selected set of chemicals is present within the environmental air sample; determine at least one of a chemical name, a chemical concentration, a chemical category, or a toxicity level; transmit the determined information to a central data collection site; utilize multiple wearable chemical detectors in a single general area, wherein the wearable chemical detector communicates with each other information relating to chemical concentrations measured to generate an instruction; and receive the instruction by at least one wearable chemical detector for a user to follow, wherein the instruction includes an indication of whether an alert from an alert mechanism in the at least one chemical threat detector of one or more detected chemicals present is a false positive. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
