Nortek Security & Control LLC, a Nortek Company and a leader in the security and smart home markets, today announced the addition of three new home safety products to the GoControl® portfolio of devices.
LRAD Corporation, the world's leading provider of Long Range Acoustic Devices® and advanced ONE VOICE® mass notification systems, today announced it has received opening orders totaling over $735,000 for perimeter security and public safety in Asia and for a southeastern U.S. utility installation. The orders are comprised primarily of LRAD 1000X, LRAD 1000RX and LRAD 500RX systems.
Electrical engineers at the University of California, San Diego developed a receiver that can detect a weak, fast, randomly occurring signal. The study, published in the Dec. 11 issue of Science, lays the groundwork for a new class of highly sensitive communication receivers and scientific instruments that can extract faint, non-repetitive signals from noise. The advance has applications in secure communication, electronic warfare, signal intelligence, remote sensing, astronomy and spectroscopy.
A dolphin’s echolocation beam was directed at a submerged man and the echo captured by a hydrophone system. The echo signal was sent to a sound imaging laboratory who created the first ever ‘what-the-dolphin-saw’ image of the submerged man, by using a cymatic-holographic imaging technique.
Still early in his career, Fan-Chi Lin has distinguished himself by the wide range of his research contributions, particularly in the area of using ambient noise to construct images of the Earth's crust and upper mantle. Since his Ph.D. was awarded in 2009, Lin has become one of the originators and leading experts on this type of imaging.
This media-art installation was created as part of the project trees: Rendering Ecophysiological Processes Audible, run jointly by ZHdK and WSL.
Ultrasound, a non-invasive technique commonly used to study the presence of atherosclerosis disease in blood vessels, can be used to identify patients at increased risk of future stroke who could benefit from surgery. Since surgical treatment to prevent stroke is only considered beneficial to some, ultrasound can prove useful in preventing unnecessary surgical intervention, new research at Umeå University in Sweden shows.
This winter, two sounding rockets will launch through the aurora borealis over Norway to study how particles move in a region near the North Pole where Earth's magnetic field is directly connected to the solar wind. After the launch window opens on Nov. 27, 2015, the CAPER and RENU 2 rockets will have to wait for low winds and a daytime aurora before they can send their instrument payloads soaring through the Northern Lights.
The technological development has international recognition and has sparked interest for industrial production by a manufacturer in the medical sector.
Raytheon Company has completed delivery of its latest Modular Scalable Sonar System (MS3), the fifth-generation hull-mounted sonar system, for the Defense Advanced Research Projects Agency (DARPA)'s Anti-Submarine Warfare Continuous TrailUnmanned Vessel (ACTUV) program. The delivery is a culmination of efforts under a subcontract from Leidos, Inc., whose prototype trimaran is designed to serve as the program's unmanned vehicle.
