Abstract: There is provided an aerosol delivery device including a power source and controller, the controller being configured to control delivery of power from the power source to an aerosol-generator during a single aerosol-generation event according to a first power delivery profile and a subsequent power delivery profile having a different profile to the first power delivery profile, wherein the first power delivery profile has a predetermined output based on the voltage of the power supply.

Abstract: A method for the dissemination of audio information in a hostile environment via an airdrop to mainly illiterate populations in a target area by means of a leaflet (10, 14) containing audio circuitry (12). In the first step (1) the hostile target population is identified and the desired content of the audio information is selected. In the next steps, hardened, waterproof audio leaflets (10, 14) are manufactured (2) and recorded (4), (5) with the desired audio information. Finally, the audio leaflets are then airdropped (6) to the target population. The audio message is played (7) when the leaflet is activated by a member of the target population. The method is practiced using an audio leaflet designed to play an audio message. The leaflet (10, 14) is embodied in a protective structure capable of surviving (i) an impact resulting from and airdrop and (ii) extended exposure to adverse elements of nature for at least three days.

Abstract: A loudspeaker has a horn adapted to both cause air drag and to direct acoustic waves. A speaker and signal generator are electrically coupled to the speaker and secure to the horn. The loudspeaker is transported over a target and dropped from a high elevation. Upon landing the loudspeaker commences broadcasting a message. A shock absorber may secure to the horn and absorbs some of the shock of impact. Contact sensors or motions sensors may trigger broadcasting a message from the speaker. A portion of the horn may be expandable to increase the size of the horn upon deployment or upon impact with the ground.

Abstract: A compact lightweight electro-acoustic transducer system for generating high intensity, highly directional audio output. The transducer system can generate acoustic intensity levels that can drive the transmission medium to non-linearity such that highly directional secondary sound also can appear in the audible range allowing direct and parametric sound generation from a single acoustic emission system. The device can be used for both distant and/or high intensity communications to convey information, provide high intensity acoustical targeting and/or disrupt or mask other communications.
