"DSLR design principles" posted by ~Ray
Posted on 2007-12-20 20:12:03

A camera based on the (SLR) principle uses a mirror to show the image that ordain be captured in a. The cross-section (side-view) of the optical components of an SLR shows how the light passes through the lens assembly (1) is reflected into the pentaprism by the reflex mirror (which must be at an exact 45 degree angle) (2) and is projected on the change focusing screen (5). Via a condensing lens (6) and internal reflections in the roof (7) the image is projected either focused or unfocused through the eyepiece (8) to the photographer's eye. Focusing is usually automatic activated by pressing half-way on the shutter release or a dedicated AF button as is mainly the case with an autofocusing film SLR; or manual where the photographer manually focuses the lens by turning a lens ring on the lens barrel. When an image is photographed the mirror moves upwards in the direction of the arrow the (3) opens and the image is projected and captured on the sensor (4) after which actions the shutter closes the mirror returns to a critical 45 degree angle and the diaphragm reopens and the built in drive mechanism retensions the close for the next exposure. Depending on the position of the reflex mirror (down or up) the lighten from the scene can only reach either the or the sensor. Therefore most DSLRs do not currently provide "" (allowing and depth-of-field preview using the display) a facility that is always available on digicams. The advantages of an optical viewfinder are that it alleviates eye-strain sometimes caused by electronic view finders (EVF) and that it constantly shows (except during the change integrity second of time for the sensor to be exposed) the exact visualise that will be exposed because its light is routed directly from the lens itself. Compared to ordinary digital cameras with their and/or the advantage is that there is no time lag in the image; it is always correct as it is being "updated" at the speed of lighten. This is important for challenge and/or sports photography or any other situation where the subject or the camera is moving too quickly. Furthermore the "resolution" of the viewed image is much better than that provided by an LCD display or an electronic viewfinder which can be important if manual focusing is desired for precise focusing as would be the case in photomacrography or photomicrography (commonly referred to as "macro-photography" and "micro-photography"). A disadvantage of the DSLR optical viewfinder system is that it prevents the possibility of.

"Traic" posted by ~Ray
Posted on 2007-12-12 16:20:12

Because individual SCRs are more flexible to use in advanced hold back systems they are more commonly seen in circuits desire motor drives while TRIACs are usually seen in simple low-power applications desire household dimmer switches. A simple lamp dimmer go is shown here complete with the phase-shifting resistor-capacitor network necessary for after-peak firing. TRIACs are notorious for not firing symmetrically. This means they usually won't initiate at the claim same gate voltage level for one polarity as for the other. Generally speaking this is undesirable because unsymmetrical firing results in a current waveform with a greater variety of harmonic frequencies. Waveforms that are symmetrical above and below their average centerlines are comprised of only odd-numbered harmonics. Unsymmetrical waveforms on the other hand include even-numbered harmonics (which may or may not be accompanied by odd-numbered harmonics as well). In the interest of reducing total harmonic content in cater systems the fewer and less diverse the harmonics the better -- one more reason why individual SCRs are favored over TRIACs for complex high-power control circuits. One way to make the TRIAC's current waveform more symmetrical is to use a device external to the TRIAC to time the triggering pulse. A DIAC placed in series with the gate does a bring together job of this: DIAC breakover voltages tend to be much more symmetrical (the same in one polarity as the other) than TRIAC triggering voltage thresholds. Since the DIAC prevents any furnish current until the triggering voltage has reached a certain repeatable aim in either direction the firing inform of the TRIAC from one half-cycle to the next tends to be more consistent and the waveform more symmetrical above and below its centerline. Practically all the characteristics and ratings of SCRs apply equally to TRIACs object that TRIACs of course are bidirectional (can handle current in both directions). Not much more needs to be said about this device object for an important caveat concerning its terminal designations. From the equivalent circuit diagram shown earlier one might think that main terminals 1 and 2 were interchangeable. They are not! Although it is helpful to create by mental act the TRIAC as being composed of two SCRs joined together it in fact is constructed from a single conjoin of semiconducting material appropriately doped and layered. The actual operating characteristics may differ slightly from that of the equivalent model. This is made most evident by contrasting two simple circuit designs one that works and one that doesn't. The following two circuits are a variation of the lamp dimmer circuit shown earlier the phase-shifting capacitor and DIAC removed for simplicity's sake. Although the resulting go lacks the fine control ability of the more complex version (with capacitor and DIAC) it does function: However if this circuit is built it ordain be found that it does not work! The fill will acquire no power the TRIAC refusing to fire at all no matter how low or high a resistance determine the hold back resistor is set to. The key to successfully triggering a TRIAC is to make sure the gate receives its triggering current from the main terminal 2 side of the circuit (the main terminal on the opposite side of the TRIAC symbol from the furnish terminal).

"Satellite Communication - The Transponder System Part V" posted by ~Ray
Posted on 2007-11-22 02:55:31

By [http://ezinearticles com/?expert=John_Dulaney]John Dulaney Commercial companies like Hughes. Aerospatiale and Lockheed Martin undergo been designing satellites to continually keep up with the growing bespeak for satellite phones. TVs and data services. These companies have achieved this at the expense of greater spacecraft size and cater. This expense is particularly true for geostationary orbiting satellites which requires larger transmission power and high gain dish antenna diameters to overcome the tremendous communicate loss during its path through the 35,000 km from hide to the air and vice-versa. To begin with satellites designs are at first cocenptualised which provides a alter planning regarding the purpose of the air and to investigate the systems necessary to complete its mission. What follows next is the preliminary design and basic design stages. During the preliminary stage a copy is constructed for experimentation to evaluate if the new technologies incorporated in the satellite can be realised during this basic design re-create. An engineering model is made after this and intense testing of all the parameters is made in-order to establish the design viability. There are quite a few shapes that satellites are constructed. There are the Spherical ones cylindrical shapes box shapes and the multi-mission module system where the two parts the bus and the mission equipment are divided into upper and lower sections. The bus system carries many sub-systems such as the telemetry tracking and command system the electrical power system attitude control system propulsion system structural system and thermal hold back system. The shapes of any air are decided on the basis of the size and the weight carried by the air. In discussing the working of a air relating to displace/receive of information from the Earth displace to the satellite and vice-versa we had in the previous artcles looked at the basic principle of the antenna system deployed in such applications. There is another divide in a satellite which provides the same functional part of this send/receive process. This component is called a transponder. The Transponder The term Transponder which is the bunco create of Transmitter-responder and sometimes abbreviated to XPDR. XPNDR or TPDR is open in telecommunication applications. This is a device that receives signals from the Earth station amplifies it and sends them for processing. The processed data is re-transmitted by the transponder back to the Earth displace in a different frequency other than that of the received one. As discussed in the past articles a separation in frequencies between the received and the transmitted signals are maintained in-order to provide enough margins for a possible interference. A Transponder is also used for transmitting say messages in response of an electronic interrogation. Transponders are the individual communication channels of a satellite each being a transreceiver or a repeater. With digital signaling several video and audio channels may be multiplexed and compressed and made to jaunt through a single transponder on a single wide band carrier. We have discussed the matter about frequency bands in one of the earlier articles. We have also explained what is meant by frequency which is measured in Hertz (Hz). The communication signals are communicate waves carried by what is termed as a ‘carrier frequency’. In order to examine what a carrier frequency is - the method of how a carrier frequency is technically utilised in communication needs to be briefly discussed. Basically there are four types of techniques by which signals are transmitted and these are - amplitude modulated (AM) signals frequency modulated (FM) signals or phase modulated (PM) signals. This is briefly discussed below. Let us suppose that the signal as illustrated in Figure (1) needs to me transmitted using Amplitude Modulation (AM) technique. In this inspect a carrier signal is generated. A carrier frequency is a constant frequency which carries the generated signal. The affect is shown in evaluate (1). Here the communicate generated is modulating the amplitude of the carrier communicate and this is the signal which is transmitted. In case of Frequency Modulation (FM) the carrier frequency is modulated by the frequency of the signal being transmitted. unlike AM. You will notice a variation in the frequency of the carrier communicate in proportion to the frequency of the signal to be transmitted. Figure (2) illustrates the example. As for arrange Modulation the information signal is transmitted by the instantaneous variation of the phase of the carrier signal by the signal to be transmitted. This principle is not very much used unlike its most popular counterpart frequency modulation (FM). This is because of the cerebrate that it tends to require more complex receiving hardware and there can be ambiguity problems with determining whether for example the communicate has 0 phase or 180 phase. Figure (3) illustrates an example. Transponders are transmitters and responders of satellites. The job of a transponder is to receive the signal from the earth station which gets modulated amplified and re-transmitted as an up-linked communicate. The Transponder is a part of the payload of a telecommunication satellite and there could be 20 to 30 of them in such a satellite. The carrier signals discussed above are received by the transponders at very low power owing to the distance that it needs to jaunt from the respective Earth stations to the satellite placed about 35,000 miles above hide. These signals need to be amplified to a good extent and then re-transmitted to the designated hide stations. It has a set of high power amplifiers where each of these amplifiers works on different frequencies. The combination of the devices which transmit and receive along-with the amplifier system is known as the Transponder. This equipment includes the high power amplifier and electronic filters at the input and output of the amplifiers.. These separate devices filter the carrier frequencies from the ones reaching the transponder and isolates those meant for processing by the other transponders. It is the central element in a satellite which maintains end-to-end cerebrate between the hide stations and the satellite. In such communication scenario the up-link from the Earth stations to the satellite has its contribution in distorted signals reaching the satellite as will the down-link have while transmitting signals from the air to the hide stations. Some of these distortions are not co-related. In order to correct these distortions the individual contributions must be known. The process of up-link and down-link signal conditioning is quite complex and is briefly discussed here. In order to understand this simplified presentation there are certain terms which be to be explained. Modulator - Figures (1). (2) and (3) represents the various techniques used in signal transmission. The figures be a carrier signal the communication communicate and lastly the modulated carrier signal. The carrier signal is modulated by the communication communicate or the signal which needs to be transmitted. This is done by an electronics system called ‘Modulator’. In the context of this discussion it is enough to understand that the communication communicate modulates the carrier communicate and then this composite signal is processed for transmission. De-modulator - As the composite modulated signal gets.

Confused about phase converters? You are not alone. A lot of populate including qualified electricians are confused also. But. arrange Converters can be a great thing for your obtain. It can bring you the ability to change more efficient and be 3-phase motors for your equipment. 3 arrange motors are smaller and can case a lot more horsepower into a smaller lay. But. I don't need to express you about the advantages of 3 phase cater. I'm sure. Of course many of the Logosol products are available in 3 Phase although some are now available in single phase. Logosol has recently begun offering a high quality Rotary arrange Converter to our customers at a low price just so they ordain be more apt to take favor of 3 Phase cater. So now it's more incentive than ever to act up to 3 arrange power in your shop. If you don't undergo both of these conditions then you ordain not get the full use of your phase converter. It ordain run but you will not get full cater out of your equipment in certain operations. So if you do not undergo these criteria met you ordain be better off with single phase equipment. If you undergo the above two items you ordain need to add a 100 amp go breaker for the phase converter. This will cater the phase converter. Then your three phase wiring ordain come out of the phase converter and be distributed to the appropriate equipment. One way to do this is to feed a three phase electrical panel box from the phase converter and put breakers in this box for each conjoin of equipment. I've include in this divide a picture of one of our phase converters installed in the Wichern woodworking shop in Missourri. They had an electrician do a great job of installation for their shop. This is what a good installation should be desire. The box to the left is the 100 Amp go Breaker. Not shown is the main electrical panel that feeds this breaker. At the furnish of the photo is the phase converter and then the top right box is the 3 phase electrical adorn. Notice the conduit connecting the 3 phase box with the 100 amp circuit breaker. Two legs for the 3 phase box are coming from the breaker and one leg from the phase converter. You can see a for this on Smith Electric's website. You can construe more about phase converters there. But overall phase converters are simple to install. Just make sure you undergo adequate power to your facility. Find a good electrician who understands 3 phase power and you should undergo no trouble getting your converter installed. Be sure to follow local codes for your installation and use a qualified electrician. We are always here for consultation if you need assistance as well as the manufacturer of the phase converter. apply 3 Phase cater!

"Electrical Generator" posted by ~Ray
Posted on 2007-10-25 17:09:31

An electrical generator is a device that converts mechanical energy to electrical energy generally using electromagnetic induction. The source of mechanical energy may be a reciprocating or turbine steam engine wet falling through a turbine or waterwheel an internal combustion engine a wind turbine a transfer crank or any other source of mechanical energy. Early 20th century Alternator made in Budapest. Hungary in the power generating hall of a hydroelectric displace. Historic developmentsBefore the connection between magnetism and electricity was discovered generators used electrostatic principles. The Wimshurst machine used electrostatic induction or "influence". The Van de Graaff generator uses either of two mechanisms: * Charge transferred from a high-voltage electrode * Charge created by the triboelectric effect using the separation of two insulators (the belt leaving the displace pulley)Electrostatic generators are used for scientific experiments requiring high voltages. Because of the difficulty of insulating machines producing very high voltages electrostatic generators are made only with low cater ratings and are never used for generation of commercially-signifimove quantities of electric cater. FaradayPortable generator side view showing gasoline engine. In 1831-1832 Michael Faraday discovered that a potential difference is generated between the ends of an electrical conductor that moves perpendicular to a magnetic field. He also built the first electromagnetic generator called the 'Faraday disc' a type of homopolar generator using a copper disc rotating between the poles of a equip magnet. It produced a small DC voltage and large amounts of current. DynamoThe dynamo was the first electrical generator capable of delivering power for industry. The dynamo uses electromagnetic principles to alter mechanical rotation into an alternating electric current. A dynamo machine consists of a stationary structure which generates a strong magnetic handle and a set of rotating windings which move within that handle. On small machines the magnetic field may be provided by a permanent magnet; larger machines undergo the magnetic handle created by electromagnets. The first dynamo based on Faraday's principles was built in 1832 by Hippolyte Pixii a cut instrument maker. It used a permanent magnet which was rotated by a go. The spinning magnet was positioned so that its north and south poles passed by a conjoin of iron wrapped with wire. Pixii found that the spinning magnet produced a beat of current in the equip each time a impel passed the turn. Furthermore the north and south poles of the magnet induced currents in opposite directions. By adding a commutator. Pixii was able to convert the alternating current to enjoin current. Unlike the Faraday disc many turns of equip connected in series can be used in the moving windings of a dynamo. This allows the terminal voltage of the forge to be higher than a disc can produce so that electrical energy can be delivered at a convenient voltage. The relationship between mechanical rotation and electric current in a dynamo is reversible; the principles of the electric motor were discovered when it was found that one dynamo could cause a second interconnected dynamo to rotate if current was fed through it. Jedlik's dynamoÁnyos Jedlik's single impel electric starter (dynamo) (1861)In 1827. Anyos Jedlik started experimenting with electromagnetic rotating devices which he called electromagnetic self-rotors. In the prototype of the single-pole electric starter (finished between 1852 and 1854) both the stationary and the revolving parts were electromagnetic. He formulated the concept of the dynamo at least 6 years before Siemens and Wheatstone. In essence the concept is that instead of permanent magnets two electromagnets opposite to each other bring forth the magnetic handle around the rotor. Gramme dynamoBoth of these designs suffered from a similar problem: they induced "spikes" of current followed by none at all. Antonio Pacinotti an Italian scientist fixed this by replacing the spinning turn with a toroidal one which he created by wrapping an iron go. This meant that some move of the coil was continually passing by the magnets smoothing out the current. Zénobe Gramme reinvented this design a few years later when designing the first commercial cater plants which operated in Paris in the 1870s. His create by mental act is now known as the Gramme dynamo. Various versions and improvements have been made since then but the basic concept of a spinning endless loop of wire remains at the heart of all modern dynamos. ConceptsThe generator moves an electric current but does not create electric rush which is already show in the conductive equip of its windings. It is somewhat analogous to a wet handle which creates a flow of wet but does not act the wet itself. Other types of electrical generator exist based on other electrical phenomena such as piezoelectricity and magnetohydrodynamics. The construction.
