The 2-meter amateur radio band is a portion of the VHF radio spectrum that comprises frequencies stretching from 144 MHz to 148 MHz in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia). The license privileges of amateur radio operators include the ...The 100 metres, or 100-meter dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, the 100-meter (109.36 yd) dash is one of the most popular and prestigious events in the sport of athletics.It has been contested at the Summer Olympics since 1896 for men and since 1928 for women. The inaugural World Championships were in 1983.Micrometer (device), used for accurate measurements by means of a calibrated screw. Micrometre, a millionth of a metre. Category:Multimeter. Analog multimeter. Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.

A sound level meter (also called sound pressure level meter ( SPL )) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. [1] The diaphragm of the microphone responds to ...by Gina Trapani by Gina Trapani Last month I was surfing the collaboratively-edited free encyclopedia Wikipedia, as I'm wont to do, and I came across a typo.

Italian physicist and electrical engineer Galileo Ferraris publishes a paper on the induction motor, and Serbian-American engineer Nikola Tesla gets a US patent on the same device [4] [5] 1890. Thomas Alva Edison invents the fuse. 1893.Thermal resistivity. The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by , , or and is measured in W·m −1 ·K −1 . Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.The meter communicates to its collection point using 900 MHz mesh network topology. Automatic meter reading ( AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and ...

MAF sensor in a 2006-2015 automotive diesel engine. A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine.. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.Radio waves are generated artificially by an electronic device called a transmitter, ... Equivalently, the distance a radio wave travels in a vacuum, in one second, is 299,792,458 meters (983,571,056 ft), which is the wavelength of a 1 Hertz radio signal ... ….

MULTIFUNCTIONAL WITH A 100 METER RANGE.In electronics, crosstalk is a phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit or channel to another.. Where the electric, magnetic, or traveling fields of two electric signals overlap, the ...Repeater. A radio repeater retransmits a radio signal. In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.

The net result is a distance from the face of the transducer that is blind and cannot detect an object. It is known as the "blanking zone", typically 150 mm to 1 m, depending on the range of the transducer. The requirement for electronic signal processing circuitry can be used to make the ultrasonic sensor an intelligent device.Survey meters in radiation protection are hand-held ionising radiation measurement instruments used to check such as personnel, equipment and the environment for radioactive contamination and ambient radiation. ... This was before the era of electronic indicators, which started with the introduction of the Dekatron tube in the 1950s. ...
