USS Arthur W. Radford with the aft mast replaced by the proof-of-concept AEM/S. USS New Orleans with fore and aft AEM/S.. The US Navy's Advanced Enclosed Mast/Sensor (AEM/S) system fully integrates advanced materials, structures, and manufacturing technologies with sensor technology, electromagnetics, and signature reduction.
An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. [1] It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman. [1]
The EMD AEM-7 is a twin-cab four-axle 7,000 hp (5.2 MW) B-B electric locomotive built by Electro-Motive Division (EMD) and ASEA between 1978 and 1988. The locomotive is a derivative of the Swedish SJ Rc4 designed for passenger service in the United States .
A recent invention demonstrates using close-packed fractal resonators to make the first wideband metamaterial invisibility cloak at microwave frequencies. [22] [23] Fractal filters (a type of tuned circuit) are another example where the superiority of the fractal approach for smaller size and better rejection has been proven. [24] [25] [26]
Wideband signals can be converted to conventional quattro signals [13] and vice versa. [14] In February 2016, Sky (UK) launched a new LNB only compatible with their new wideband tuner. [15] This LNB has one port for all vertical polarised channels both low and high band, and another port for all low and high band horizontal channels.
A millimeter wave scanner at Cologne Bonn Airport, Germany, Europe. A millimeter wave scanner is a whole-body imaging device used for detecting objects concealed underneath a person’s clothing using a form of electromagnetic radiation.
The Wideband Networking Waveform (WNW) is a military radio protocol for mobile ad hoc networking (MANETs) for software defined radios. [1] It was developed as part of the Joint Tactical Radio System (JTRS) program of the U.S. Department of Defense , and was intended for US and NATO military use.
Conduction band profile of a photoconductive QWIP. The conduction band profile is tilted as a bias voltage is applied. A Quantum Well Infrared Photodetector (QWIP) is an infrared photodetector, which uses electronic intersubband transitions in quantum wells to absorb photons.
