20080277196 | Engine and technique for generating an acoustic signal - A device for generating an acoustic signal in a fluid includes an engine operable to repeat a thermodynamic process to vibrate a membrane of the engine to generate an acoustic signal having more than one period. The thermodynamic process includes heating mass inside a chamber of an engine to generate pressure inside the chamber; in response to generating the pressure, moving in a first direction a portion of a membrane of the engine; removing mass from inside the chamber to decrease the pressure inside the chamber; and in response to decreasing the pressure inside the chamber, moving the membrane portion in a second direction. Because the engine repeats the thermodynamic process, the engine can generate and sustain an acoustic signal for a significant amount of time. In addition, because the heat in the engine's chamber is generated by a chemical reaction, the engine may quickly generate a significant amount of pressure inside the chamber to quickly accelerate the membrane, and thus generate a powerful acoustic signal. Furthermore, various properties of the membrane and/or the thermodynamic process may be modified to tune the acoustic signal to a desired frequency and/or amplitude. Thus, the engine may be effectively used to generate acoustic signals for a number of different purposes, such detecting and ranging objects in a region, and in a number of different marine environments, such as a littoral environment that contains a large amount of noise, or a deep sea environment at high water pressure. | 11-13-2008 |

20090138123 | Robotic CBRNE Automated Deployment, Detection, and Reporting System - A system having a plurality of networked detectors for detecting chemical, biological, or radiological, nuclear, or explosive agents is disclosed. The system includes a plurality of remote units, wherein each remote unit includes a robotic base, a lift, a sensor module, transceiver, navigation system, and power source. The remote units communicate with a base station, which receives data from the remotes and determines, based on the data, if an alarm condition exists. | 05-28-2009 |
