Patent ID: 7666356

Claim:
A trace sampling detection system comprising: a gathering device configured to gather particles through each of: a handle-bar including collection holes positioned to be adjacent to a user's hand when the user grips the handle bar, wherein the handle-bar is configured to release particles in response to a grip and motion of the user, a gate including a series of collection holes positioned to be adjacent to the user's clothing when the user traverses the gate, wherein the gate is configured to release particles in response to pressure applied from the user and is configured to open only when the handle-bar is moved, an air-stream gatherer including an outward vent and an in-drawing vent positioned to enable objects to be placed between the outward and in-drawing vents, wherein the air-stream is configured to release particles from objects that block the air-stream between the outward and in-drawing vent; a collection tube configured to deposit gathered particles from the gathering device onto a portion of a sample media; a carousel wheel that includes the sample media and is configured to rotate the sample wheel such that the portion of the sample media including the gathered particles is presented to an exothermic decomposition detector; and an exothermic decomposition detector configured to detect, through an infrared sensor, the decomposition of the gathered particles.
