Count the number of stacked "rings" on the insulator and multiply by 10kV; this will give you a rough estimate. THAT IS B.S. TRANSMISSION IS 500KV SO YOUR FRIEND WANTS 50 OF THOSE B.S. THAT IS NO CORRELATION TO THAT. BUT DISTANCE IS A VERY GOOD FACTOR TRUST ME ON THAT.

It's simple and straight forward. If things go wrong with an aircraft in flight, there can be catastrophic consequences. It is a good idea to monitor and maintain avionics systems so that things don't go wrong in flight. It would suck to be out of fuel if the gauge had failed. It would be bad to be in the wrong place because the VOR was out of wack. The list goes on.

the new:they use energy to turn ONE gear that turn the rest, thus using less energy by only turning ONE the] the old:they use energy to turn the whole thing, thus using more energy

Amplitude Modulation

The DVD has arguably thousands of practical applications, from Frisbees to backing up extremely critical data. The name itself implies that it is good for many things, Digital Versatile Disk. DVDs are used as a medium to distribute movies, software, games, operating systems, business files, etc.

When metal passes in front of the switch the magnet inside either makes or breaks an electrical connection depending on if it is a normally open or normally closed type switch. When the metal is removed the switch moves back to its normal position. These are particularly useful in applications where it might be exposed to water since the switch is completely enclosed. Connected to a relay the switch can activate or stop a hydraulic valve when a part has reached its proper position.

Comparator is usually a substance which compares two quantities; one quantity is the processed one and the other is a standard value to which the processed value has to be compared. Hysteresis is a property in which the change in the magnetization lags behind change in the magnetic field. Now, Hysteresis comparator can be described as a comparator which compares a processed quantity with a quantity whose value is standard for hysteresis property., the difference being given as the output

The input impedance of a current shunt feedback amplifier is the open loop impedance of the amplifier divided by 1+(A*beta)

You will have to determine its scaling factor. The output of the ADC is a number, you can interpret it anyway that is necessary for the system it is in.

The series circuit described (if understood correctly) is a series tank circuit. It is a tuned circuit. The C and the L are capacitance and inductance, respectively, and they are said to be in series. What that translates into is that as an AC signal passes through them, they "ring" electronically (they oscillate) a certain amount depending on the frequency of the signal that is put in. Based on the C and the L, there will be one frequency that the circuit will like to run at, and this will be the resonant frequency (fo) of the series tank circuit. A maximum amount of oscillation can be expected at fo, and the tank is tuned for that frequency. But what if a signal is above or below fo? Signals above and below fo will not cause as much oscillation as the one right at fo. And the farther from fo they are, the less oscillation they will cause. If we graph the output (eo) of a stage (with frequency on the x-axis and gain on the y-axis) that has this kind of tuned circuit in it, we'll see a sharp peak at fo and a general falling off on either side. The farther from fo the input signal is, the less gain. This is true for signals both above and below fo. There is a slight difference in response as regards the slope of the flanks of that peak. The lower frequencies will fall off "forever" but the higher ones will fall of about the same as the lower ones to a point and then will not suffer much more attenuation. That's because at frequencies above fo, the circuit will have stronger capacitive characteristics, and the higher fequency signals will be coupled through. A graph of this circuit can be seen by using the link provided. There is also a link to the Wikipedia article on the RLC circuit from which this graph came. Lastly, the amount of R in the RLC circuit will determine the quality factor (Q) of the circuit. The quality determines how high and how wide the peak on our graph will be. Higher R means less quality. Lower R will result in higher Q. The higher Q circuit will have a higher and sharper peak. The lower Q circuit will have a lower but wider peak. The quality is a determinant in bandpass. Lower Q circuits will have higher (broader or wider) bandpass.

45nm technology refers to size of the transistors in a chip. A technology node is defined as the ground rules of a process

governed by the smallest feature printed in a repetitive array.

The half-pitch of first-level interconnect dense lines is most

representative of the DRAM technology level required for the

smallest economical chip size . This is currently chosen

as the dimension that defines a technology node. It is, however,

anticipated that in the future, the half-pitch dimensions of either

metal or polysilicon interconnections of microprocessors

(MPUs) and ASIC devices may rival or even become smaller than

the corresponding half-pitch of DRAM. The half-pitch dimension

however, may not represent the smaller feature of the chip.

For instance, for logic devices, such as MPUs, physical bottom

gate length represents the smallest feature. Nevertheless, the

technology node definition remains tight to the half-pitch indicator

as defined above. see this ref. for more http://ieeexplore.ieee.org/iel5/101/21453/00994854.pdf?arnumber=994854

Releasing Freon into the atmosphere is a Federal crime. Leave it alone as there is no need to release the R-12. Just remove the A/C belt if it only drives the A/C. If it drives other components, just remove the fuse. If you insist, then take the car to an A/C shop or your dealer and have them remove the Freon with the proper recovery equipment. You may even be able to sell it to them due to the extremely high price of Freon.

Milller's Theorem is used to simplify a circuit for circuit analysis. Instead of one impedance, which connectes two non-grounded nodes, Miller's Theorem allows this impedance to be broken down into two parallel impedances. One impedance can be seen as Z/(1-A) and the other impedance can be simplified to Z/(1-(1/A)). In this case, Z was the value of the original impedance, and A is the gain of the amplifier being analyzed.

Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.

A load chart....is a chart usually found on the arm of a crane. It shows you how much the machine is rated to lift at specific points of the lift under ideal conditions. In equipment with telescopic booms; the weights that it can lift varies ( the further you have to extend; the less weight it can bear), as well as turning radius under load also varies. The more you turn your crane under load the less stable your crane can become causing it to topple over if you don't abide by the chart and try to lift more then it's rated capacity. Although a load chart is the most important chart you must understand before operating a piece of machinery such as this, it does not take into account other factors that can effect a load such as; wind speed, condition of the equipment, how to rig or sling a load, or any other deciding human factor. Take a crane course before messing with this kind of equipment. Learn how to read a load chart properly. your life is worth more then the equipment that could topple over and kill you.

The pnp switch is short for Park/Neutral Switch. Its pretty much the middle man between the ignition switch and the starter. It only allows the current from the ignition switch to reach the starter if the vehicle is in park or neutral. Its usually connected to the shifter. Allow me to correct myself on the first answer. If the shifter is on the column it will be located in the column region. If shifters on the floor its under the vehicle and connected to the shifter.

In electronics, gain measures how much bigger an amplifier's signal output (or the output of some other circuit) is relative to its signal input.

The word "gain" can be ambiguous; "a gain of seven" may imply that either the voltage, current, or the power is increased by a factor of seven.

For example,

When listening to music on the radio, a series of stages converts and amplifies (with a some gain at each stage) an almost imperceptible over-the-air signal, step by step, into a rhythm coming out your speakers as loud as you want it.

First, consider an upgrade. Older monitors used 54mhz 5 watt transmitters that had limited range. Newer monitors use the 800-900 mhz band, which have better range, but can run into interference from cordless phones and other wireless devices.

The simplest way to improve the range of radio frequency (RF) devices is to focus and aim the signal. Search youtube for 'cheap wifi signal booster' and you'll see dozens of tips for creating parabolic and half-cylinder shapes out of foil. These solutions are typically aimed at wifi routers, but the principle will work just as well for baby monitors. If your monitor does not have an external antenna, just place the base in front of the parabola/half cylinder and aim it in the general direction of the receiver.

To get around interference or obstructions like steel framework, block walls, or foil insulation, you could chain two monitors together to get around the obstacle. By chain, I mean place the receiver of the first unit next to the base of the second unit. (This has obvious drawbacks, but it worked for us.)

If you are handy and don't mind voiding your warranty, you could crack open the base unit and extend the antenna. To get the best performance, your antenna will need to be the proper length. You'll need to know the frequency (e.g. 900mhz) in order to determine the length of the antenna. The wavelength of a 900mhz signal is 33cm. Optimal antenna lengths are 1, 1/2 or 1/4 the wavelength. A practical 1/4 wave antenna for a 900mhz baby monitor would be 8.25cm.

The good news is that external 900mhz antennas are common and you can buy one in the $10-$60 range. (I'd go cheap if for this project.) To get around obstructions, you can run a cable between the base and the antenna, but the more cable you use, the greater your loss of signal will be.

tune up. new plugs wires and distribitor cap. and maybe new fuel filter and air filter
