Abstract: An integrated mine detection system includes a ground penetrating metal detector and a ground penetrating radar detector. The integrated mine detection system includes an integrated search device housing a radio-wave transmitter of the radar detector and a coil of the metal detector. The radio-wave transmitter includes an antenna. The integrated search device includes a radio-wave receiver in the form of a pair of receiving antennas.

Abstract: A trace sampling detection system includes a gathering device configured to gather particles through a handle-bar, a gate and an air-stream gatherer. The handle-bar includes collection holes positioned to be adjacent to a user's hand when the user grips the handle-bar, and is configured to dislodge and capture particles from the user's hand when the user grips and moves the handle-bar. The gate includes a series of collection holes, is positioned to be adjacent to the user's clothing when the user traverses the gate, and is configured to dislodge and capture particles from the user's clothing in response to pressure applied from the user. The air-stream gatherer includes an outward vent and an in-drawing vent, and is positioned to enable objects, such as the user's feet, to be placed between the outward and in-drawing vents. The air stream is configured to dislodge and capture particles from objects, such as the user's feet, that block the air-stream between the vents.

Abstract: Improved gripping structures for a hand-held umbrella are provided. In one example structure, a first grip is fixedly attached to an end of a shaft of the umbrella, such as the end located distally away from a canopy of the umbrella. A second grip is coupled to the shaft. The second grip may be slidably repositionable along the shaft. The second grip may include an interlocking device to lock the second grip at a desired location along the shaft. The second grip may further include a runner interface. An accessory mount may be disposed at the first grip to couple an accessory, such as a camera, at the end of the shaft distally away from the canopy of the umbrella.

Abstract: A trace sampling detection system includes a gathering device configured to gather particles through a handle-bar, a gate and an air-stream gatherer. A collection tube is configured to deposit gathered particles from the gathering device onto a portion of a sample media. A carousel wheel that includes the sample media 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 that detects, through an infrared sensor, the decomposition of the gathered particles.
