Abstract: Disclosed is a composition and method for the inflation of passive restraint systems, i.e., crash bags. The method, which uses the gases produced by the ignition of certain alkali metal azides in combination with certain metal halides for inflation of the bag, provides a non-toxic gas for inflation. Use of sufficient metal halide to provide halogen in an amount at least stoichiometric with the alkali metal prevents the formation of free alkali metal, the latter considered to be toxic and to present an unsuitable material in passive restraint systems.

Abstract: A circuit coupling an antenna to a load uses an integrated circuit differial amplifier with emitter feedback, a buffer amplifier and various adjusting networks to achieve constant output impedance independent of input loading over a wide range of frequencies. The adjusting networks also allow precision gain matching and phase matching between units.
