Electromagnetic field monitors, as used in the cellular phone industry, are referred as "personal RF safety monitors", personal protection monitors (PPM) or RF exposimeters. [1] They form part of the personal protective equipment worn by a person working in areas exposed to radio spectrum radiation. A personal RF safety monitor is typically ...
Frequency response. In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and phase of the output as a function of input frequency. [1] The frequency response is widely used in the design and analysis of systems, such as audio and control systems, where they simplify mathematical ...
Sweep frequency response analysis. Sweep frequency response analysis ( SFRA) is a method to evaluate the mechanical integrity of core, windings and clamping structures within power transformers by measuring their electrical transfer functions over a wide frequency range.
Blockbuster was banned from including photocopies of original, copyrighted instruction booklets with its rented games. In compliance with the ruling, Blockbuster produced original short instructions—usually in the form of a small booklet, card, or label stuck on the back of the rental box—that explained the game's basic premise and controls.
Multiburst. A multiburst waveform is a useful test pattern used to quickly ascertain the frequency response of a video system. The name derives from the multiple bursts of sine wave in the active video section of the waveform which are generated with (usually) increasing frequency, but identical in amplitude.
A ribbon microphone, also known as a ribbon velocity microphone, is a type of microphone that uses a thin aluminum, duraluminum or nanofilm of electrically conductive ribbon placed between the poles of a magnet to produce a voltage by electromagnetic induction. Ribbon microphones are typically bidirectional, meaning that they pick up sounds ...
Schirmer's test uses paper strips inserted into the eye for several minutes to measure the production of tears. Both eyes are tested at the same time. Most often, this test consists of placing a small strip of filter paper inside the lower eyelid (inferior fornix). The eyes are closed for 5 minutes. The paper is then removed and the amount of ...
NEW YORK (Reuters) -U.S. stocks closed with slight gains on Tuesday as investors assessed the latest round of comments from Federal Reserve officials for clues on the timing of a rate cut and the ...
