Abstract: Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.

Abstract: Disclosed are fibers which contain identification fibers. The identification fibers can contain a one or more of chemical markers and one or more distinct features, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The chemical markers and distinct features can be representative of specific supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer. The disclosed embodiments also relate to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and distinct features and correlating the chemical markers and distinct features to manufacturer-specific taggants to determine supply chain information.

Abstract: A sight base is configured to receive and secure a sighting device and is coupled to a base by a pin running in each of the grooves and rotatable about the pins between an aligned position with the base extending between the parallel walls and the optical device aligned with the sighting axis, and a deployed position rotated away from the aligned position. A detent releasably retains the sight base in the aligned position. A clamp member is carried on the lower extent of the base, and releasably engages the rail with selectively movable to tighten and secure the clamp and base to the rail. A lever is coupled to the base and to the clamp member, and has a camming surface configured to move the movable portion of the clamp into and out of engagement with the rail in response to actuation of the lever. The camming surface of the lever bears on a resilient surface carried by the base.

Abstract: A Terahertz scanning imaging device for imaging objects where the object is larger than the object to imager distance. The imager comprises scanning elements, sensors, and an image processor. The scanning elements are used to direct radiation to the sensors. Multiple scanning elements and sensors may be used, each scanning a portion of the field of view. The image processor, in communication with the sensors, generates a consolidated 2-dimensional image of a field of view.

Abstract: An optical beam steering arrangement, comprises: a moveable optical element; actuating means for causing the movement of said element; a connecting means between said element and said actuating means for transmitting movement from said actuating means to said element; and flexure means which carry said optical element and are compliant with the displacement of said optical element.

Abstract: An optical guide switching assembly in which steering devices are used to assembly deflect radiation from a transmitting guide to a selected receiving guide. Each of the steering devices includes a collimator for light emerging from the transmitting guide and an actuator to cause relative movement between the collimator and the guide to cause the deflection, or to move the guide and collimator together. The actuator can be piezoelectric and of either a foil type, or a monolithic type, and mechanical leverage can be used to improve deflection. Capacitive sensing means provide positional information for feedback control, preferably in a diagonal switching arrangement.
