Happy New Year. So what does ATCO have in store for it in 2006? It looks like the you know what hit the fan the last Q of 2005. Url

Patent App, LRAD 12/29, Small, Medium, and Large. Approx. 1 ft, 1.5 ft, and 2.5 ft. They haven't introduced the one foot unit to the public, as of yet. Hey, Supersize me! It would be interesting to see what a 6 footer would be capable of, but that size would be impractical for most uses. == United States Patent Application 20050286346 Kind Code A1 Croft, James J. III ; et al. December 29, 2005 -------------------------------------------------------------------------------- High intensity directional electroacoustic sound generating system for communications targeting 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. -------------------------------------------------------------------------------- Inventors: Croft, James J. III; (Poway, CA) ; Beauchamp, Todd; (Poway, CA) ; Conrad, Terry; (Poulsto, WA) Correspondence Name and Address: THORPE NORTH & WESTERN, LLP. 8180 SOUTH 700 EAST, SUITE 200 SANDY UT 84070 US Serial No.: 131453 Series Code: 11 Filed: May 16, 2005 U.S. Current Class: 367/140; 340/384.1 U.S. Class at Publication: 367/140; 340/384.1 Intern'l Class: B06B 001/06; G08B 003/00 -------------------------------------------------------------------------------- Claims -------------------------------------------------------------------------------- 1. An electro-acoustic sound generator system for generating a high intensity directional sound column in a far field comprising: an acoustic emitter with at least one transducer acoustic emission region; at least one power amplifier channel adapted to receive at least an audio signal; at least a length of the emitter being scaled to be at least four times a wavelength of a lowest frequency of at least one maximum acoustic output primary acoustic signal; at least a depth of the emitter being scaled to be less than one fourth the dimension of the length; and the emitter being configured and tuned to exhibit high efficiency over at least a narrow bandwidth corresponding to a frequency range of maximum sensitivity of a human auditory system, to generate a directed high intensity sound beam with an axial acoustic output of at least 140 dB at a minimum of 2 meters. 2. The sound generator of claim 1 wherein the acoustic emitter consists of multiple transducer acoustic emission regions. 3. The sound generator of claim 2 wherein the multiple acoustic transducer emission regions are staggered for optimal packing density and grouped such that each group is in a different mounting plane. 4. The sound generator of claim 3 wherein at least two groups of transducers in one plane relative to another plane are driven in different phase relationships to maximize axial summation of output in the far field. 5. The sound generator of claim 1 wherein at least one primary acoustic signal is between 1500 and 4000 Hz. 6. The sound generator of claim 5 wherein the length of the acoustic emitter is at least 0.33 meter. 7. The sound generator of claim 5 wherein the length of the acoustic emitter is at least 0.5 meters. 8. The sound generator of claim 5 wherein the length of the acoustic emitter is at least 0.75 meters. 9. The sound generator of claim 5 wherein the emitter is substantially circular in form and has a diameter of at least 0.75 meters. 10. The sound generator of claim 5 wherein the emitter is substantially rectangular in form and has a cross section of at least 0.5 square meters. appft1.uspto.gov
