Abstract: A system for delivery of a message to a subscriber over multiple communications channels includes means for accepting the message from a sender, means for determining a sequence of the communications channels for delivery of the message based on a subscriber profile, and means for delivery of the message over at least one of the communications channels until acknowledgement of message receipt by the subscriber.

Abstract: The invention is a side by side nylon/nylon bicomponent yarn with desirable stretch and recovery and retractive force characteristics, and the process for manufacturing this yarn.

Abstract: A method for removing color and extracting dyes from ionically dyeable polymeric materials is provided. The method includes contacting the ionically dyeable polymeric material with a swelling agent for the material under conditions sufficient to effect diffusion of the dye from the material. The process is especially useful for removing colors from ionically dyeable polymeric materials as part of a recycling process for such materials. Also, the extracted dye may be recovered for re-use as the swelling agent and contacting composition are substantially non-reactive with the dye.

Abstract: A sensor having a substrate overlayed with a sol-gel layer, a chemical sensing species deposited upon the sol-gel layer, and a thin film of a second sol-gel layer overlaying and entrapping the species. The effect of this sensor is that the species exhibits a significant portion of its intrinsic function over a period of time. In yet another embodiment of the subject invention, a method is disclosed to form a thin sol-gel layer upon an ambient substrat. This method ensures the integrity, stability and functionality of the chemical sensing species within the sol-gel layers.

Abstract: An individual mine launcher is designed to pneumatically launch high explve VOLCANO and MOPMS mines to simulate flight and impact typically encountered in field use. Electronic components and controls are used to monitor and initiate the arming sequence of the mine. Two configurations are used with the same pneumatic and electronic controls. The air-launch configuration allows the mine to be launched into the air at various specified testing elevation angles. The control impact configuration shoots the mine into a chamber where the mine hits an impact surface and then falls into a test monitoring area below.
