Abstract: A method (100), a system and, a computer program product for bulk communication of information to recipients via multiple delivery media are disclosed. The media include facsimile, email, surface mail, SMS messaging, and archiving (and is adapted for new media types in the future). A single interface is used to receive information (106, 108, 110) for distribution including one or more template documents (110) and data (106) specific to each recipient. At least one document based on the received information (106, 108, 110) is transmitted using a specified delivery media (144, 150, 156, 162, 168) for each recipient based on the recipients' delivery preferences (122, 176). Escalating (172, 178) transmission of the document may occur using a different delivery media for any recipients for whom transmission by the specified delivery media fails. The escalating step (172, 178) may depend upon status information (176) from a carrier regarding delivery of the document to each recipient.

Abstract: The present invention relates to a silencer for reducing muzzle blast and noise of firearms or similar devices. The present silencer has a hollow cylindrical or other shape casing comprising front and rear end caps and an opening aligned along a longitudinal axis defining a passage for a projectile and propellant gases to emerge from the muzzle opening. A plurality of serially placed baffles of symmetrical or slanted orientation and intervening coaxial spacers are positioned within the casing and define a multitude of chambers among the baffles, spacers, and outer housing. The baffles shear propellant gases away from the projectile path and through openings or ports into additional chambers formed between the spacers and outer housing. The arrangement of baffles and spacers provides flow-impeding paths, dispersion, and controlled expansion of gases and lowers gas temperature to reduce audible noise and observable signature of the muzzle blast.
