What is the priority of an application Windows is a multitasking system. It means that a lot of various applications are running simultaneously in it. You directly work with some of them, but some of them work invisibly and independently. The priority of an application is a parameter that tells the system which task has priority over other tasks. For example, if there are two programs that are running simultaneously and with the same priority, they will have equal shares of the processor time. But in case you set a higher priority for one of them, the program that has this higher priority will use all the free processor time while the one with a lower priority will use only the rest of it. For example, if you have an application for rendering a video clip running on your computer, it will use the free processor time sharing it equally with, say, Explorer. It will result in Explorer working jerkily. But if you set a lower priority for the rendering program, it will use only the time that Explorer does not need. Explorer will work more smoothly and faster. It is also convenient to set a higher priority for multimedia players the playback will be smoother. If you have some database service running on your computer, it is useful to set a lower priority for it so that it does not interfere with the work of those applications you are using at the moment. You can change the priority of processes on the Processes tab of Task Manager. Lightscape 3.2 there. Prio automatically detects any changes in priority and saves them in its settings. Next time you start this application, its priority will be restored. Dont get it twisted, Prio does lots more then just saverestore priority, we actually like it for all the other features, check out the screen shots you wont be disappointed, we highly recommend this one. Pantograph transport Wikipedia. A pantograph or pan is an apparatus mounted on the roof of an electric train, tram or electric bus1 to collect power through contact with an overhead catenary wire. It is a common type of current collector. Typically, a single wire is used, with the return current running through the track. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Inventionedit. Early 1. Baltimore Ohio Railroad electric locomotive. The brass contact ran inside the section bar, so both lateral and vertical flexibility was necessary. The pantograph, with a low friction, replaceable contact strip to minimise lateral stress on the contact wire, was invented in 1. Walter Reichel, chief engineer at Siemens Halske in Germany. A flat slide pantograph was invented in 1. Baltimore and Ohio Railroad4The familiar diamond shaped roller pantograph was invented by John Q. Brown of the Key System shops for their commuter trains which ran between San Francisco and the East Bay section of the San Francisco Bay Area in California. They appear in photographs of the first day of service, 2. October 1. 90. 3. For many decades thereafter, the same diamond shape was used by electric rail systems around the world and remains in use by some today. The pantograph was an improvement on the simple trolley pole, which prevailed up to that time, primarily because the pantograph allows an electric rail vehicle to travel at much higher speeds without losing contact with the overhead lines. Modern useeditThe most common type of pantograph today is the so called half pantograph sometimes Z shaped, which has evolved to provide a more compact and responsive single arm design at high speeds as trains get faster. Louis Faiveley invented this type of pantograph in 1. The half pantograph can be seen in use on everything from very fast trains such as the TGV to low speed urban tram systems. The design operates with equal efficiency in either direction of motion, as demonstrated by the Swiss and Austrian railways whose newest high performance locomotives, the Re 4. Taurus, operate with them set in the opposite direction. The geometry and shape of the pantographs are specified by the EN 5. IEC 6. 04. 86 Railway applications Current collection systems Technical criteria for the interaction between pantograph and overhead line to achieve free access9Technical detailsedit. The asymmetrical Z shaped pantograph of the electrical pickup on the Berlin Straenbahn. This pantograph uses a single arm design. The electric transmission system for modern electric rail systems consists of an upper, weight carrying wire known as a catenary from which is suspended a contact wire. The pantograph is spring loaded and pushes a contact shoe up against the underside of the contact wire to draw the current needed to run the train. The steel rails of the tracks act as the electrical return. As the train moves, the contact shoe slides along the wire and can set up standing waves in the wires which break the contact and degrade current collection. This means that on some systems adjacent pantographs are not permitted. A Flexity Outlook LRV with its pantograph raised. Note the trolley pole in the rear, which provides compatibility with sections not yet upgraded for pantograph operation. Pantographs are the successor technology to trolley poles, which were widely used on early streetcar systems. Trolley poles are still used by trolleybuses, whose freedom of movement and need for a two wire circuit makes pantographs impractical, and some streetcar networks, such as the Toronto streetcar system, which have frequent turns sharp enough to require additional freedom of movement in their current collection to ensure unbroken contact. However, many of these networks, including Torontos, are undergoing upgrades to accommodate pantograph operation. Pantographs with overhead wires are now the dominant form of current collection for modern electric trains because, although more fragile than a third rail system, they allow the use of higher voltages. Pantographs are typically operated by compressed air from the vehicles braking system, either to raise the unit and hold it against the conductor or, when springs are used to effect the extension, to lower it. As a precaution against loss of pressure in the second case, the arm is held in the down position by a catch. For high voltage systems, the same air supply is used to blow out the electric arc when roof mounted circuit breakers are used. Single and double arm pantographsedit. High performance pantograph used for measurements on the ICE SPantographs may have either a single or a double arm. Double arm pantographs are usually heavier, requiring more power to raise and lower, but may also be more fault tolerant. On railways of the former USSR, the most widely used pantographs are those with a double arm made of two rhombs, but since the late 1. Russian railways. Some streetcars use double arm pantographs, among them the Russian KTM 5, KTM 8, LVS 8. Russian made trams, as well as some Euro PCC trams in Belgium. American streetcars use either trolley poles or single arm pantographs. Metro systems and overhead linesedit. Symmetrical, diamond shaped pantographs on trams in Prague. Most rapid transit systems are powered by a third rail, but some use pantographs, particularly ones that involve extensive above ground running. Hybrid metro tram or pre metro lines whose routes include tracks on city streets or in other publicly accessible areas, such as the MBTA Green Line, naturally must use overhead wire, since a third rail would normally obstruct street traffic and present too great a risk of electrocution. Among the various exceptions are several tram systems, such as the ones in Bordeaux, Angers, Reims and Dubai that use a proprietary underground system developed by Alstom, called APS, which only applies power to segments of track that are completely covered by the tram. This system was originally designed to be used in the historic centre of Bordeaux because an overhead wire system would cause a visual intrusion. Similar systems that avoid overhead lines have been developed by Bombardier, Ansaldo. Breda, CAF, and others. These may consist of physical ground level infrastructure, or use energy stored in battery packs to travel over short distances without overhead wiring. Overhead pantographs are sometimes used as alternatives to third rails because third rails can ice over in certain winter weather conditions. The MBTA Blue Line uses pantograph power for all of its surface route. The entire metro systems of Madrid, Barcelona, Shanghai, Hong Kong, Seoul, Kobe, Fukuoka, Sendai, and Delhi use overhead wiring and pantographs as well as portions of the metro systems in Beijing, Chongqing, Tokyo, Osaka, Nagoya, and Sapporo. Pantographs were also used on the Nord Sud Company rapid transit lines in Paris until the other operating company of the time, Compagnie du chemin de fer mtropolitain de Paris bought out the company and replaced all overhead wiring with the standard third rail system used on other lines. The Chicago Transit Authoritys Yellow Line used both third rail and pantograph collection, switching from the former to the latter at roughly halfway from Howard station towards the terminus at DempsterSkokie station and vice versa. The overhead portion was a remnant of the Chicago North Shore and Milwaukee Railroads high speed Skokie Valley Route,1. Chicago subway system to utilize pantograph collection for any length. As such, the line required railcars that featured pantographs as well as third rail shoes, and since the overhead was a very small portion of the system, only a few cars would be so equipped. The changeover occurred at the grade crossing at East Prairie, the former site of the Crawford East Prairie station.
