Audible warning device, английский
A device, such as a whistle, siren, horn or hooter, used to give warning.
Detector, английский
- A general term applied to parts of instruments which are designed to detect ionising radiation . ionising radiations interact with the detector, the detector converts this interaction into a signal which can be amplified and interpreted by other devices.
- Детектор; датчик-измеритель; чувствительный элемент
- A device such a photodiode or photodetector that converts optical energy into electrical energy. they can be made from silicon, germanium, gallium arsenide, indium gallium arsenide or from other semiconductors, depending on the wavelengths to detect. the positive-intrinsic-negative (pin) and the avalanche photodiode (apd) types are used in fiber optics. pin types can be used for analog or digital systems, while apds with their internal amplification can only be used in digital systems
- A device that generates an electrical signal when illuminated by light. the most common fiber-optic detectors are photodiodes.
- Детектор, датчик
Detector (rt), английский
A device that determines the presence of ionizing radiation.
Detector coil, английский
- See sensing coil. detector, xray: sensor, xray.
- См. чувствительную катушку. детектор, рентген: датчик, рентген.
- See coil, sensing.
Detector de mentiras, английский
Una maquina que registra por una aguja en un grafico que varia disturbios emocionales al contestar las preguntas sincera y/o falsamente, como indicado por fluctuaciones en la presion de sangre, la r
Detector element, английский
Чувствительный элемент
Detector log video amplifier, английский
Detector probe, английский
- Adjustable or fixed device through which air and/or tracer is drawn into the leak test instrument and over the sensing element or detector. response is measured in units of pa·m3 · s or std cm3/s. standard flow rate is measured at standard temperature and pressure. also called sampling probe; sniffer probe.
- In leak testing, an adjustable or fixed device through which air and/or tracer gas is drawn into the leak test instrument and over the sensing element or detector. also called a sampling probe or a sniffer probe.
Detector probe test, английский
- Pressure leak test in which the leakage of a component, pressurized with a tracer rich mixture, is detected by scanning the test object with a detector probe connected to an electronic leak detector. leakage tracer gas is pulled from the leak through the probe inlet to the sensing element to cause a visible or audible signal on the indicator of the leak test instrument.
- In leak testing, pressure leak test in which the leakage of a component, pressurized with a tracer rich mixture, is detected by scanning the test object boundary surface with a detector probe connected to an electronic leak detector. leakage tracer gas is pulled from the leak through the probe inlet to the sensing element to cause a visible or audible signal on the indicator of the leak test instrument.
Detector scanning, английский

Auto balance, английский
- System used in colour cameras to detect and automatically correct errors in the amplitude of colour signals.
- A system for detecting errors in color balance in white and black areas of the picture and automatically adjusting the white and black levels of both the red and blue signals as needed for correction.
Attenuation, английский
- The decrease in magnitude of a signal, as it travels through a medium. used to describe signal loss in a transmission system. measured in decibels (db).
- Поглощение
- Зависимость снижения мощности сигнала от расстояния. для оптоволоконных кабелей обычно выражается в дб/км
- In general terms, a reduction in signal strength.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or
- The difference between transmitted and received power due to loss through equipment, lines, or other transmission devices; usually expressed in decibels. the loss in power of electromagnetic signals between transmission and reception points.
- The decrease in magnitude of a wave, or a signal, as it travels through a medium or an electric system. it is measured in decibels (db).
- The loss of optical power, whether caused intrinsically (absorption, scattering, microbends, etc.), or extrinsically by components (connectors, splices, splitters, etc)
- The decrease in radiation energy (power) as a beam passes through an absorbing or scattering medium.
- Reduction of signal magnitude, or loss, normally measured in decibels. fiber attenuation is normally measured per unit length in decibels per kilometer. the decrease in signal strength along a fiber optic waveguide caused by absorption and scattering. attenuation is usually expressed in db/km.
- A reduction in the effect or strength of something such as a virus, either because of environmental conditions or as a result of a laboratory procedure
- Ослабление
- Ослабление (затухание). уменьшение количества радиации при ее прохождении через вещество в результате всех видов взаимодействия с этим веществом. ослабление обычно не связано с уменьшением геометрических размеров (мос, 5). ослабление солнечной радиации — потеря энергии световым лучом при его прохождении через атмосферу земли. потеря энергии обусловлена рассеянием света молекулами воздуха, селективной абсорбцией молекулами определенных веществ и рассеянием света аэрозолями (вмо).
- The weakening of a transmitted signal, such as the distortion of a digital signal or the reduction in amplitude of an electrical signal. attenuation is usually measured in decibels and is sometimes desirable, as when signal strength is reduced electronically, for example, by a radio volume control, to prevent overloading.
- The weakening of a transmitted signal, such as the reduction in the brightness of light, as it travels farther from its source.
- Regulatory system of prokaryotes whereby secondary stem-loop structures formed within the 5’ end of an mrna being transcribed determine both if transcription to complete the synthesis of this mrna will occur and if this mrna will be used for translation
- Decrease in transmitted energy intensity over distance. the loss may be due to absorption, scattering, reflection, leakage, beam divergence, or other material effects.
- Снижение интенсивности передаваемой энергии на расстоянии. потери могут быть вызваны поглощением, рассеянием, отражением, утечкой, расходимостью луча или другими материальными эффектами.
- Decrease in signal magnitude during energy transmission from one point to another. this loss may be caused by absorption, reflection, scattering of energy or other material characteristics or may be caused by an electronic or optical device such as an attenuator.1
- (1) decrease in energy or signal magnitude in transmission from one point to another. can be expressed in decibels or as a scalar ratio of the input magnitude to the output magnitude.16 (2) change in signal strength caused by an electronic device such as an attenuator. (3) decrease in intensity caused by absorption, leakage, reflection, scattering or other material characteristics. see also neper.
- (1) decrease in acoustic energy over distance. this loss may be caused by absorption, leakage, reflection, scattering or other material characteristics. (2) decrease in signal amplitude caused by acoustic energy loss or by an electronic device such as an attenuator.10,16,21
