Abstract: An automated fiber optic rotary joint (FORJ) dynamically measures, using an angle encoder, twists in an optical fiber cable caused by movements of a mouse or other animal and automatically unwinds the optical fiber cable(s) by engaging a motor. To optimize its efficiency, the unwinding process is activated automatically only when the angle encoder reaches a predetermined threshold. In some embodiments, the optical fiber is unwound in increments of 360°. Various embodiments allow simultaneous transfer of optical signals through independent channels to and from multiple sites of a freely moving animal through a rotating interface and with minimal mechanical impact on the natural behavior of the animal. The design principle leads to a minimal variation of light transmission over rotation suitable for life science applications. A single channel FORJ device can be readily expanded to a two-, three- or more-channel device.

Abstract: Vapor wake detection is a highly advantageous method and system for detecting explosives and other illicit substances. With vapor wake detection, a canine and a handler are used; however, unlike other detection schemes, the canine leads the handler. After the handler positions the canine in a desired location, the canine detects scents in the air that come to the canine. When the canine detects a trained scent, the canine leads the handler to or follows behind the carrier of the item with the scent. Once the carrier is identified by the handler, the proper personnel are contacted. To implement vapor wake detection effectively, specific rigorous training is utilized.
