Abstract: A message is formed by capturing at least one image of an individual, and producing a first signal representative thereof. A signal is transmitted based upon both the first signal and a second signal which indicates a selected image from a plurality of predetermined images. The message is reconstructed from a received radio frequency signal which contains a third signal representative of the at least one image of the individual and a fourth signal indicative of the selected image. The selected image is retrieved from a plurality of prestored images based upon the fourth signal. At least one combined image is displayed based upon the at least one image of the individual, provided by the third signal, and the selected image.

Abstract: One aspect of the present invention discloses a deflagration suppression system, which is particularly applicable to delagrations involving combustible gases. The deflagration suppressant in the system is typically water which is dispersed in the combustible gas as a stream of droplets having a Sauter mean Diameter of no more than about 80 microns. The system can include a combustible substance detector to detect potentially explosive concentrations of a combustible substance, such as the combustible gas, before the onset of a deflagration.Another aspect of the subject invention discloses a liquid atomizing device which is particularly applicable to the deflagration suppression system. The liquid atomizing device atomizes the liquid in a carrier gas and the liquid droplets are further decreased in size by increasing the velocity of the droplets to a supersonic velocity.
