| 20080225644 | Deployable Audible Protection - The invention relates to an acoustic protection system used to secure a determined zone of interest and to remotely control an individual or a group of individuals within this zone and with a potentially hostile behavior. The system comprises at least one set of N electro acoustic sound sources forming a network and a generator used to create N electrical signals output from a same reference and that can be controlled in phase individually. Each electrical signal is input into a determined sound source, the assembly creating a resulting emission for which the diagram depends on the direction of the zone of interest and the distribution of required active and quiet zones. The device also comprises means capable of determining the relative positions of the different sources after they have been deployed, thus limiting positioning constraints imposed on operators responsible for deployment and making the work faster. The purpose of the invention is more generally the domain of non-lethal protection devices. | 09-18-2008 |

| 20100110838 | Acoustic Deterrence - A method and system of deterring mammals is disclosed involving incurring an acoustic startle response comprising the steps of selecting a target order, family, genus or species to be deterred, selecting a received level that is a predetermined level above a representative hearing threshold of the targeted mammals, and, taking transmission loss into account, transmitting an acoustic signal at a source level required to create the selected received level at a predetermined distance from the transmission point. The acoustic signal may comprise frequency components at which the aural sensitivity of the targeted mammals is greater than that of selected other animals, preventing the disturbance of the selected other animals whilst deterring the targeted mammals. In addition, a secondary conditioning sound may be played prior to the main acoustic signal to condition the mammals to avoid the main stimulus. Furthermore, using the same steps, an aversive stimulus may be played that elicits an avoidance without a startle reflex. The characteristics of these aversive sounds are those found to be unpleasant to humans. Accordingly, the aversive sound is selected to have one or more of the following psychophysical features: high roughness; low tonality; high loudness; high sharpness. | 05-06-2010 |

Each source is capable of generating an acoustic signal and a controller determines the firing time for each source to produce signals, which may include precisely timed wave trains of superimposed tones on a broadband low frequency signal, which are believed most effective in deterring seals, sea lions and other carnivorous mammals. The system may further include a sensing device to determine the presence of marine mammals so that the acoustic deterrent can be initiated on demand. | 07-21-2011 |
| 20110235467 | MAN-PORTABLE NON-LETHAL PRESSURE SHIELD - A man-portable non-lethal pressure shield provides both a physical as well as pressure shield. The pressure shield addresses the concerns of military, police and human rights organizations and international law as regards effectiveness, efficiency and safety and efficiency. A folded acoustic horn is incorporated into the physical shell of the shield. The horn couples acoustic pulses from a sonic pulse generator to an acoustic aperture to output a pulsed pressure beam that approximates a plane wave to produce a pressure barrier. The operator may specify a desired effect on its human target that is maintained as range-to-target changes or a desired effect at a specified perimeter range. The shields may be networked to facilitate coordinated action among multiple pressure shields as a force multiplier or to provide a more sophisticated pressure barrier. | 09-29-2011 |
| 20120026839 | PEST-CONTROL DEVICE - A pest-control device that repels pests with sound is illustrated and described.

Sound-transmission openings in the pest-control device can be positioned to selectively direct sound sideways along the wall including the socket. This can increase the effectiveness of the device at repelling pests in corners along the edges of floors and countertops, where pests tend to travel. The pest-control device also can include a light sensor that detects the ambient light level. An output volume can be permanently configured or temporarily configured to increase in response to a signal or absence of signal from the light sensor. For example, the pest-control device can be configured to increase the volume of pest-repelling sound at night when pests are most active and people and pets typically are not present. | 02-02-2012 |

| 20140211594 | ACOUSTIC TAG HAVING A DIGESTIBLE FUSE - Acoustic tags have been used for years in fisheries research to study survival and behavior of fish in various aquatic environments. The described techniques, devices and systems enhance the ability of researchers to understand the effect on fish mortality by predators through an acoustic tag that includes a digestible fuse. When the implanted acoustic tag comes in contact with the digestive fluids in a predator's stomach, the fuse coating is dissolved causing the fuse to disintegrate and result in an open circuit. The open circuit in turn signals the electronics in the acoustic tag that the tagged fish has been consumed. In response, the electronics alter the tag transmit signal to indicate that predation has occurred. | 07-31-2014 |
