General-Purpose Analyzer Systems
Brüel & Kjær Sound & Vibration A/S
Sonoscout is a system that uses an app on an iPad to control a wireless data acquisition unit. This rugged front-end can connect up to 12 transducers, such as a binaural headset for in-vehicle recording at the user's ear positions. The front-end is battery-powered and transmits data to the iPad for recording or records directly to SD card inside the front-end, avoiding the need to use Wi-Fi. The intuitive app makes it simple to either perform basic analysis, or to replay and listen to files in order to validate recordings before exporting them for further analysis and archiving in PULSE Reflex.

Sound Quality Evaluation Function for O-Solution
OS-0525
The sounds generated from the equipment are mainly measured by evaluation based on general analysis such as sound pressure level, FFT analysis and 1/3 Octave analysis. However, since those analysis don’t take into consideration the human hearing characteristics enough, sounds with even the same analysis result may give different impression.When a human listens to a sound, various sensations such as loudness, sharpness, and roughness occur.

VECTOR-GUN HANDHELD DIRECTION FINDING ANTENNA SYSTEM
HFDF
National RF's Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum. Due to the nature of a Faraday shielded loop, the antenna exhibits a sharp null through the diametric center of the loop. This null is used to determine the direction of incoming radio signals or to locate electrical noise being radiated from some source. The internal high gain amplifier is used to compensate for the inherent inefficiency of the actual loop at the operating frequency. Overall, the system dynamic response is about +6 dB as compared to the dynamic response of a dipole. To aid in the direction finding process on strong signals, an internal 30 DB attenuator is provided. As the loop antenna presents a bi-directional response, tri-angulation may be required to eliminate the ambiguous signal direction. The line of site of the incoming signal is determined by listening for a signal null on the receiver or by watching the receiver’s S-meter.

Hydrophones
Piezo is a critical element in producing a hydrophone for military and commercial underwater listening applications. Hydrophones utilize piezoelectric elements to detect sound pressure waves produced by underwater vessels, animals, and the environment. Hydrophones must have a flat frequency response that is proportional to the magnitude of the sound pressure wave. CTS piezo elements provide this critical function in hydrophones by providing excellent frequency response and high coupling factors necessary in hydrophone applications. CTS materials provide excellent electrical properties for hydrophone applications while allowing the ability to form the piezo element to the desired mechanical structure for the hydrophone.

Text Analysis
Text analytics is the process of transforming unstructured text documents into usable, structured data. Text analysis works by breaking apart sentences and phrases into their components, and then evaluating each part’s role and meaning using complex software rules and machine learning algorithms. Data analysts and other professionals use text mining tools to derive useful information and context-rich insights from large volumes of raw text, such as social media comments, online reviews, and news articles. In this way, text analytics software forms the backbone of business intelligence programs, including voice of customer/customer experience management, social listening and media monitoring, and voice of employee/workforce analytics.

Receiver Semi-Kit
75-NS-3
National RF’s 75-NS-3 receiver is a complete super-hetrodyne mini high frequency receiver, designed specifically for the short-wave listener, electronics enthusiast or radio amateur, who wants to use their hands and build a radio. The receiver is offered as a semi-kit in which the electronic assembly is loaded and functionally tested at the National RF facility. The customer must then go to the grocery store (yes…the grocery store!), procure a can of lunch meat, eat it or give it to the dog, and then proceed to drill and paint the can, in order for it to become the receiver’s enclosure! As the name of the preferred potted meat can has a registered trademark by Hormel Foods, Inc., it won’t be mentioned on this web-site. However, the name of the product is synonymous with unwanted email!!! In addition, there are other food products that might be found that are packaged in the same metallic enclosure. Detailed drilling instructions and final assembly instructions are provided as part of the kit. All other parts required for completion of the receiver are provided as well. Recognizing that the finished assembly looked somewhat like the fabled Collins receiver of the ‘60s, the 75S-3, (particularly when the can is painted a light gray) National RF engineers dubbed it (with tongue firmly planted in cheek, of course) the 75-NS-3! Although we have had fun packaging this receiver in a lunch meat can, it is nothing to turn your nose at! Its performance and portability will surprise you, and it is an ideal radio to bring with you on any trip!
