81Multimeter — A digital multimeter A multimeter or a multitester, also known as a VOM (Volt Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability …
82RONJA — (Reasonable Optical Near Joint Access) is a Free Space Optics device originating in the Czech Republic. It transmits data wirelessly using beams of light. Ronja can be used to replace a segment of LAN, and one can enjoy all activities as if they… …
83The Dark Energy Survey — DES logo The Dark Energy Survey (DES) is a survey that aims to probe the dynamics of the expansion of the universe and the growth of large scale structure. The collaboration is composed of research institutes and universities from United… …
84RF MEMS — The MEMS acronym stands for Micro Electromechanical System and is used to refer to components of which sub millimeter sized parts need to move for the components to have electronic functionality. RF MEMS passives, such as capacitors, inductors,… …
85RONJA — Une seule DEL haute luminosité avec une lentille simple loupe crée un faisceau lumineux étroit permettant de transmettre un flux vidéo sur le quartier. Quelques pas à côté et le faisceau devient invisible …
86Force spectroscopy — is a dynamic analytical technique that allows the study of the mechanical properties of single polymer molecules or proteins, or individual chemical bonds. It is performed by pulling on the system under scrutiny with controlled forces. As a… …
87Dielectric spectroscopy — A dielectric permittivity spectrum over a wide range of frequencies. The real and imaginary parts of permittivity are shown, and various processes are depicted: ionic and dipolar relaxation, and atomic and electronic resonances at higher energies …
88Mechanical insulation — Thermal insulation and acoustic insulation are installed on piping and mechanical systems to achieve one or more of the following; energy savings, personnel protection, process control, condensation control, noise reduction and reduction of… …
89Rocket engine — RS 68 being tested at NASA s Stennis Space Center. The nearly transparent exhaust is due to this engine s exhaust being mostly superheated steam (water vapor from its propellants, hydrogen and oxygen) …
90Microbolometer — A microbolometer is a specific type of bolometer used as a detector in a thermal camera. Infrared radiation with wavelengths between 7.5 14 μm strikes the detector material, heating it, and thus changing its electrical resistance. This resistance …
