In electronics, a detector is an older term for an electronic component in a radio receiver that recovers information contained in a modulatedradio wave. The term dates from the first three decades of radio (1886-1916). Unlike modern radio stations which transmit sound (an audio signal) on the radio carrier wave, the first radio transmitters transmitted information by wireless telegraphy, using different length pulses of radio waves to spell out text messages in Morse code. So early radio receivers did not have to extract a sound wave from the incoming radio signal, but only "detect" the presence or absence of the radio signal, to produce clicks in the receiver's earphones representing the Morse code symbols. The device that did this was called a detector. A variety of different detector devices, such as the coherer, electrolytic detector, and magnetic detector, were used during the wireless telegraphy era.
"Low" is the debut single by American rapper Flo Rida, featured on his debut studio album Mail on Sunday and also featured on the soundtrack to the 2008 film Step Up 2: The Streets. The song features fellow American rapper T-Pain and was co-written with T-Pain. There is also a remix in which the hook is sung by Flo Rida rather than T-Pain. An official remix was made which features Pitbull and T-Pain. With its catchy, up-tempo and club-oriented Southern hip hop rhythms, the song peaked at the summit of the U.S. Billboard Hot 100.
The song was a massive success worldwide and was the longest running number-one single of 2008 in the United States. With over 6 million digital downloads, it has been certified 7× Platinum by the RIAA, and was the most downloaded single of the 2000s decade, measured by paid digital downloads. The song was named 3rd on the Billboard Hot 100 Songs of the Decade. "Low" spent ten consecutive weeks on top of the Billboard Hot 100, the longest-running number-one single of 2008.
"Tune in for a change" is the tagline attached to Radio in the credits. The storyline is about a girl Priya who comes to the city for a job as a salesgirl in a jewellery shop,with a load of debt to pay off, played by Sarayu. She is new to the ways and customs of the city life. Her co-worker, Iniya character Shweta, gives her accommodation, since she has no place or relative home to stay in the city. Shweta goes out at every night, where Nishan’s character Manu, comes to pick her up. Whole picture of the storyline is clear, Shweta. a five star prostitute and associate Manu as pimp,for securing her business. It is a shock to Priya when she realizes the truth about Shweta and decides to leave her friendship and apartment.
X-Dream are Marcus Christopher Maichel (born May 1968) and Jan Müller (born February 1970); they are also known as Rough and Rush. They are some of the cult hit producers of psychedelic trance music and hail from Hamburg, Germany.
Muller was educated as a sound engineer. Maichel was a musician familiar with techno and reggae, and was already making electronic music in 1986. In 1989 the pair first met when Marcus was having problems with his PC and someone sent Jan to help fix it. That same year they teamed up to work on a session together. Their first work concentrated on a sound similar to techno with some hip hop elements which got some material released on Tunnel Records.
Trance
During the early 1990s they were first introduced to the trance scene in Hamburg and decided to switch their music to this genre. From 1993 they began releasing several singles on the Hamburg label Tunnel Records, as X-Dream and under many aliases, such as The Pollinator. Two albums followed on Tunnel Records, Trip To Trancesylvania and We Created Our Own Happiness, which were much closer to the original formula of psychedelic trance, although featuring the unmistakable "trippy" early X-Dream sound.
In the broadest definition, a sensor is an object whose purpose is to detect events or changes in its environment, and then provide a corresponding output. A sensor is a type of transducer; sensors may provide various types of output, but typically use electrical or optical signals. For example, a thermocouple generates a known voltage (the output) in response to its temperature (the environment). A mercury-in-glass thermometer, similarly, converts measured temperature into expansion and contraction of a liquid, which can be read on a calibrated glass tube.
Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, besides innumerable applications of which most people are never aware. With advances in micro machinery and easy-to-use micro controller platforms, the uses of sensors have expanded beyond the most traditional fields of temperature, pressure or flow measurement, for example into MARG sensors. Moreover, analog sensors such as potentiometers and force-sensing resistors are still widely used. Applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, and robotics.it is also included in our day-to-day life.

How to detect radio wave (Radio Wave Detector)!
This simple device may be useful to demonstrate electromagnetic radiation to the children. Take 30 cm of copper wire to form a loop with one OA85 point contact germanium diode and a Light Emitting Diode (LED) in series in series. This simple passive device detects the electromagnetic radiation from the mobile phone. When the radio waves from the mobile phone passed through the copper loop, the free electrons in the copper wire starts oscillating at the frequency of the mobile phone. This oscillating current of electrons are converted to DC current by the Germanium diode and the LED (Light Emitting Diode). Only a single LED without the diode should also work but due to very high internal capacitance of the LED, the copper loop de-tune. Details at: http://www.creative-science.org.uk/mobile_...

Containing a unique arrangement of 5 custom manufactured, precision ground antennas, it allows you to choose the optimum level of precision for the job in hand.
With utility infrastructures becoming more complex, locate professionals require more powerful, flexible tools. Features such as Current Direction and iLOC combine with the versatile Tx Transmitter range to deliver highly responsive locates even in tough conditions.
Integrated GPS and usage-logging options automatically generate data for customer reports, or in-house quality and safety audits to promote best working practices.
Features:
Current Direction (CD)
A powerful tool that helps operators pick out their target line from others nearby. With CD you can locate your utility quickly and eliminate wasted time following false trails.
Automatic usage logging with GPS positioning
GPS equipped RD8100 locators automatically log key locate parameters every second, providing a comprehensive picture of individual locates, or allowing you to assess usage patterns over periods of a year or more. The data generated can be used to ensure compliance with best-practice, or to identify training needs before poor work habits develop. Additionally, the data can be used for internal audits or shared with partners or clients to evidence task completion, or compliance to their requirements. Usage data can be exported in multiple file formats – for example KML for Google Maps to confirm where and when work was performed.
Combine accuracy with speed – Peak+ mode
Combine the accuracy of Peak locating with the rapid ground coverage of Guidance arrows in the new Peak+ mode. A single key press lets you check for distortion by comparing Null with Peak.
Use Power Filters™ to pinpoint and discriminate between power cables
When a signal transmitter can’t be connected, tracing individual power lines through complex networks can be a real challenge - conflicting or powerful signals confuse, or combine to create a wash of signal. With a single key press you can now utilize the harmonic properties of power signals to establish if a signal comes from one source, or from multiple cables, then trace and mark their routes.
Trace high impedance utilities with 4 kHz – and with CD
The 4 kHz locate frequency is designed for tracing high impedance lines such as twisted pair telecoms or street lighting. Since such utilities are often found in areas of dense infrastructure, you can combine 4 kHz with CD to ensure you follow the right line.
Quickly follow lines with Guidance Mode
Guidance Mode allows you to rapidly follow the path of a buried utility. Intuitive proportional arrows, a directional ‘needle’ and differentiated audio tones guide you along the target pipe or cable.
Customize the locator to your network frequencies
Up to 5 additional frequencies can be programmed into all RD8100 locators to match it to the signals found on your target networks.
Fault Find
Combine the RD8100 locator with an accessory A-frame to identify and pinpoint insulation sheath faults to within 100mm.

In electronics, a detector is an older term for an electronic component in a radio receiver that recovers information contained in a modulatedradio wave. The term dates from the first three decades of radio (1886-1916). Unlike modern radio stations which transmit sound (an audio signal) on the radio carrier wave, the first radio transmitters transmitted information by wireless telegraphy, using different length pulses of radio waves to spell out text messages in Morse code. So early radio receivers did not have to extract a sound wave from the incoming radio signal, but only "detect" the presence or absence of the radio signal, to produce clicks in the receiver's earphones representing the Morse code symbols. The device that did this was called a detector. A variety of different detector devices, such as the coherer, electrolytic detector, and magnetic detector, were used during the wireless telegraphy era.
