UK regulator Ofcom has given approval for use of cell phones on airplanes flying in European airspace and has released plans that will allow airlines to offer mobile services on UK-registered aircrafts. The cost of making a cell phone call from an air plane will be higher than making one from the ground. Cell phones can be used on air planes that have reached at least 3,000 meters.  However, airlines looking to offer this service must still satisfy other regulators about how the hardware will be used.The decision to offer in flight cell phone services now falls to individual airlines which must over-come other regulatory hurdles before the technology is considered to be fully approved.

How fuel regulator funtion ?Fuel regulator is using vacuum to pull the diafragm which hard press aspring and let fuel to flow back to tank . If the diafragm close (lowvacuum)that mean pressure will occur at fuel rail and force fuel toinject thru nozzle (injector) .If diafragm open (high vacuum) mean lowpressure at fuel rail and small amount of fuel will be injected ( duringlow revving and idling ) .Stock fuel regulator only apply 2.5kg/cm2 and consider very lowpressure . As we know during high revving vacuum will act very low anddiafragm will open widely . Thus very low pressure at fuel rail and causelagging ( RPM climb very slow ).Aftermarket fuel regulator is adjustable , not like stock one .For NA will normal fuel piping , pressure always set at 0.3psi .

is an electrical regulator designed to automatically maintain a constant voltage level.It may use an electromechanical mechanism, or passive or active electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.With the exception of shunt regulators, all modern electronic voltage regulators operate by comparing the actual output voltage to some internal fixed reference voltage. Any difference is amplified and used to control the regulation element. This forms a negative feedback servo control loop. If the output voltage is too low, the regulation element is commanded to produce a higher voltage. For some regulators if the output voltage is too high, the regulation element is commanded to produce a lower voltage; however, many just stop sourcing

SYDNEY (AFP) Australia’s competition watchdog on Tuesday said it had no objection to Google’s 3.1 billion US dollar purchase of online advertising firm DoubleClick. In a decision that Google described as a world first among anti-trust regulators, the Australian Competition and Consumer Commission (ACCC) said it had no competition concerns about the deal. "In this context, the ACCC considered that the merger was unlikely to result in a substantial lessening of competition in an Australian market," the ACCC said in a statement. In a practice common in the industry, DoubleClick installs software bits referred to as "cookies" on Internet users’ computers to track where they go online and what pages they view. Privacy advocates have expressed fears about the implications of Google and DoubleClick merging their expansive databases regarding people’s Internet activities.

Stepping up the efforts to bring greater transparency in Delhi real estate, the Union Government is considering setting a regulator to address builder-consumer complaints in the Capital. The plans will be reinforced and executed within six months, says Mr. Jaipal Reddy, the Union Development Minister. The regulator will be a quasi-judicial authority to be headed by a famous personality, informs the minister while addressing the inaugural session of an international real estate conference summit, organized by Federation of Indian Chambers of Commerce and Industry. The regulator would be established with the backing of model legislation. However, the issues such as the land prices would not be handled by the regulator. The Union Government requires encouraging State Government to pursue the suit, as land was a State subject, with whatever changes they would find suitable to incorporate. Setting up a regulator for Delhi real estate is a welcome step by the Government. Builders who follow

The Petroleum and Natural Gas Regulatory Board (PNGRB) has asked the government to take steps to ensure that there is more competition in the Indian gas market. The board, the regulatory authority for the oil and gas refining and retailing business, has asked the petroleum ministry to give an account of steps taken by the government to ensure that there is a competitive market for gas.It has suggested policy recommendations to foster such competition. These are primarily in the areas of gas transportation and city gas distribution. For instance, the board has raised the issue of the requirement of gas linkage that restricts a retailer from getting into distribution without a firm gas supply contract.

Introduction The discrete LDO design presented here came about because of the need for an LDO (low drop-out regulator) for 5V designs. Subsequently it was used successfully in two designs. There are better performing LDO parts, but they tend to be either single sourced or expensive. I wanted something cheap made from common components, and I decided to have a go at a discrete design. Initially I thought of using an op-amp, but it quickly became clear that a long tailed pair should form my error amplifier. The performance parameters are very crude : 5V nominal at up to 10mA from 6-16V. But this is very useful for battery powered and simliar designs which do not need accurate 5V rails. In the design presented, a RESET output is included. Read more Source : http://www.eclectic-web.co.uk/mike/ldo.htm Power supply circuit, power supplyShare This

This is a regulator for a 6V/3W bicycle generator system. The purpose is to switch to rechargeable batteries when the generator is idle. In addition, the device limits the voltage across the bulbs when the generator operates at a high speed. As you can see, the circuit is purely electrical. In the presented design, the switch has been moved, compared to the original to a location where the switch better functions under different circumstances. I kept the regulator on the bike for 2 years during which the circuit operated fairly satisfactorily. Thereafter, I moved on to an electronic regulator optimized for the operation with a hub dynamo.

Source : http://www.turbokeu.com Detail : I like to use the LM2941 regulator (about 5 Euro here in Belgium) instead of a cheap LM317 because of the low voltage drop over the regulator, typically 0.2-0.3V (max 0.5V at 1A) as opposed to the 1.5-2.5V dropout voltage of the LM317. With the 12 to 12.xV on a common PSU rail you get the full or almost the full 12V on your fans. The formulas for resistor calculation are the same as for a LM317, but the LM2941 has 5 pins as opposed to the 3 of the LM317 (the adjust pin is separate and a “ON/OFF” pin is also provided to remotely shutdown the regulator. The LM2941 is rated for 1A max. with some cooling. The values of R1, P1 and P2 in the schematic have been calculated for an output range from about 7 to 12V and a 10K linear potentiometer.

Voltage Regulators are used to change a sinusoidal AC signal into a DC smooth signal which remains constant independent of changes in load current. The series-pass transistor (Q1) is used for circuits which operate at higher current levels (typically currents higher than 100mA). The series pass transistor acts as a common-collector amplifier, also known as an emitter follower. The Series Pass transistor looks like it is part of the output stage of the op-amp. The effect of adding this transistor is that the current rating of the circuit now becomes dependent on the ratings of the transistor, not the ratings of the op-amp as before. The Zener diode is added to the circuit to provide a reference voltage. The Zener diode is usually chosen so that the “Zener Voltage” is about half of the output voltage.   Element Model, value D (diodes) 1N4007 Z (Zener diode) D1N4734 R1 1 Kohm R2 16 Kohm R3 20 Kohm

In a forward (or buck) regulator power is continuously supplied to the outletfilter capacitor. In a boost regulator, however, energy is pumped in a cyclic manner. The filter capacitor therefore has to be of a higher value. The boost regulator, like the flyback regulator, pumps energy into the outletfilter capacitor in a cyclic manner, and it is therefore desirable to operate in the discontinuous mode with a fixed peak current through the inductor. The diode conduction time in a boost regulator, unlike the flyback regulator, is not fixed, but varies with the input voltage.Ipk = 2 x Iout,max x (Vout / Vin,min)Tdon = (L x Ipk) / (Vout - Vin)Output voltage is regulated by controlling the duty cycle.Vout = ((Ton / Tdon) + 1) x VinRipple voltage is directly proportional to diode conduction time.Tdon max = (L x Ipk) / (Vout - Vin,max)Source : http://www.hills2.u-net.com/electron/smps.htm

My friend whant Circuit Filer power supply for Car. I to see web : http://linuxcar.sone.jp/reg.en.html good idea circuit. read simple :: At input side of regulator, I inserted a series inductor in addition to normal decoupling capacitor to form a LC filter, so that it can resist transient voltage. If supply voltage temporary goes up, it can be absorbed by regulator. But if it goes down below 13V, regulator can’t do anything but drops its output voltage. If an inductor is there, it prevents capacitor from discharging into battery side, keeping regulator’s input voltage high. It also prevents noise emission, smoothing the PC’s pulse-ish current consumption. Additionally, I added a surge suppressor diode (20V) designed especially for car electronics, to protect regulator from higher voltage than its maximum input (30V). Also a DC line filter is inserted just after the input from car, to eliminate high frequency noise. Schematic diagram of power filter/regulator circuit

With the component values shown the circuit is designed to have and output voltage range of approximately 1.25 to 13.5 Volts when measured at the output of the regulator. The calculation on the drawing is used to determine the output voltage for given values of R1 and R2. Because these regulators have a minimum output voltage of 1.25 Volts diodes D3 and D4 will provide a voltage drop of approximately 1.4 Volts so that zero output to the track can be obtained. These diodes need to have at least a 3 amp rating The diodes D1 and D2 added to the circuit will prevent damage to the regulator during certain adverse conditions such as the output voltage being higher than the input voltage to the regulator. This can happen if this type of circuit is used as a variable power supply for an electronics test bench and without the added protection of D3 and D4. A substantial heat sink will be needed for the TTR as quite a bit of heat will be generated when drawing high current with low output volta

Original source: Who knows? Has been around for decades. Description: A truly timeless circuit. LM317 is a versatile and highly efficient 1.2-37V voltage regulator that can provide up to 1.5A of current with a large heat sink. It’s ideal for just about any application. This was my first workbench power supply and I still use it. Since LM317 is protected against short-circuit, no fuse is necessary. Thanks to automatic thermal shutdown, it will turn off if heating excessively. All in all, a very powerful (and affordable!) package, indeed. Although LM317 is capable of delivering up to 37V, the circuit pictured here is limited to 25V for the sake of safety and simplicity. Any higher output voltage would require additional components and a larger heat sink. Make sure that the input voltage is at least a couple of Volts higher than the desired output. It’s ok to use a trimmer if you’re building a fixed-voltag

Concerned over poor track record of Internet Service Providers, Indian telecom regulator TRAI has recommended lowering of foreign direct investment on par with telecom sector at 74 per cent from the existing 100 per cent. ISPs having 100 per cent FDI equity should be given two years for reducing foreign holding to 74 per cent, it said. In its recommendations to Department of Telecom, TRAI has also suggested major changes in financial and regulatory levies. Instead of free entry, it recommended levying an entry fee of up to Rs 20 lakh along with a uniform licence fee of six per cent of gross revenue. ISPs seeking licence at national level will have to pay Rs 20 lakh as entry fee while it will be Rs 10 lakh for state level ISPs. The minimum annual licence fee has been pegged at Rs 5,000 for district level ISP, Rs 10,000 for state level and Rs 50,000 for national level ISP. The regulator has taken a tough stand as the objective of competition and growth of Internet have not been met. "Out
