Escalators are one form of vertical transport conveyor for transporting people, consisting of separate steps that can move up and down following the path of a rail or chain-driven motor.
Because it is driven by electric motors, escalator is designed to transport people from the bottom up or vice versa. For short distances escalator used around the world to transport pedestrians where the elevator is not practical. Its use especially in the area shopping centers, airports, transit systems, convention centers, hotels and other public facilities.
The advantage of the escalator pretty much like having the capacity to move a number of people in large numbers and there is no waiting time interval, especially at rush hour and direct people to certain places such as the exit, a special meeting etc.
The Oldest Escalators
The first escalator was made with you in 1859 in New York’s Coney Island amusement park. Because the wooden escalator accidents occurred one of the most famous in history occurred on 18 November, 1987 when the fire spread to the draft in the network of London Underground subway killed 31 people. Sparked the idea to change the basic material into iron.
The Longest Escalator
Park Pobedy station in the Gaza-Pokrovskaya Arbatsko opened in 2003 and an escalator to the length 126.8 m (413 ft), or about 740 steps. From beginning to end, the journey at Park Pobedy escalator can take nearly three minutes.
The Shortest Escalator
Because there are super long escalator which, now that its opposite. Escalator in shopping center Okadaya customs in Kawasaki, Japan, for example, only 32.8 inches long, vertical (83 cm). Approximately 3 steps when walking.

What other keyboard has a temperature range of-40F to +194 F (-40C to +90 C)? Stealth makes a lot of expensive steel NEMA keyboards, but this one looks like the most expensive.
3. TouchStream LP, Fingerworks $ 1500 +
Mystical keyboard was originally retailing for $ 340 but because Fingerworks been purchased and no longer produce the keyboard, TouchStream LPs in great condition has started to sell at a fantastic price increases. You can search on eBay you if you do not mind spending your money on computer accessories.
You all must have been listening to songs played on a tape recorder or compact disc (CD). Yes, the songs are the result of a sound recording of the singer. With voice recorder technology, we can save the sound or sounds and listen back anytime we want.
System for storing voice recordings made by sound waves in the band, LPs, or CDs. The process of recording on cassette tape can be done because it consists of a thin ribbon plasik magnetic metal powder coated.
The composition of the metal powders were irregular, but when sound is recorded into the tape, powder was made according to the sound pattern. The powder compact is what saves the recorded voice said, and then can be played anytime to listen to the voice. But to be able to listen to this voice must use the help of loudspeakers (speakers).
For CDs, this tool saves millions of votes in a small gap which represents the symbol of a series of numbers. When the CD spins, the laser beam to read the order of the hole, and the tools CD and then change the reflection ray laser into electricity. Ray is reinforced and connected with a loudspeaker which then issued a re-vote that saved it. Sound is what we hear it.
Keep in mind that each of the recording process starts from migrofon. Migrofon functions convert sound waves into electrical signals. Inside the wire gumparan migrofon there is usually mounted on a diagram. Sound waves and then create charts and coil to vibrate. These coils vibrate in the magnetic field. This vibration and generate electric current in the coil. Strong weak currents changing in accordance with the loud sound of gentle waves.
However, for the recording can be heard again need bantuab speakers. The process works namely, loudspeakers convert electrical signals into sound waves. Electric current from a source, CD or LPs, for example, turn on an electromagnet to form a magnetic field. This is what makes the cone-shaped diaphragm vibrates and then generate sound waves. This sound is the result of earlier recordings.

Apple Computer Incorporated,or more often called by “Apple” is a computer company based in Cupertino, California.
MacBook Pro, PowerBook, iBook is a computer products made by Apple Computer Inc. (line of personal computers Designed, developed, manufactured, and marketed by Apple Computer – Wikipedia), which is often called by a Mac or Macintosh
Apple is also developing an Operating System, “Mac OS” is the Operating System that was developed by Apple Computer Inc.
Previously, the Macintosh is a personal computer that uses artificial PowerPC Processor IBM / Motorola (G3 = IBM, G4 = Motorol, G5 = IBM) before using the Motorola-made 68K.
68K is a CISC Microprocessor, and PowerPC is a microprocessor RISC (Reduced Instruction Set Computing). Now, a Macintosh computer was switched to using Intel processors.
the Macintosh was launched in January 1984 with a Super Bowl ad that is very famous. Named Macintosh, taking the preferred kind of apple plants Jef Raskin.
1. Touchless Automatic Trash Can
With advanced technology, infrared sensors, this trash can opens automatically while you are within the range of 6 inches from the sensor. Three seconds after the finish, close the slide will be closed automatically.
2. Barcode trashcan
This tool is a smart bins equipped with barcode.Barcode is the code (which is usually a vertical line) that can be used to simplify the process of identifying an item. Barcode applications most easily found in supermarkets or department to expedite the service process. The waiter stayed directs the sensor to the barcode and the price will soon appear.
3. Expanding Office Bin
This trash can expand if the contents of the trash.
Microprocessor is an IC (Integrated Circuit) used as a brain / main processor in a computer system.Microprocessors are the result of growth in semiconductors.First microprocessor was introduced in 1971 by Intel Corp.,the Intel 4004 microprocessor which has a 4 bit architecture.By adding a few peripherals (memory, device I / O, etc.) 4004 microprocessor in turn into small computers by Intel.
Then the microprocessor was developed again into 8080 (berasitektur 8bit), 8085, and then 8086 (berasitektur 16bit).Dilaen laen party semiconductor company also introduced and developed a microprocessor such as Motorola with the M6800, and Zilog with Z80nya.Intel Microprocessors berasitektur 16 bits are mostly in the end by the number 86,but because the numbers can not be used to replace it with their trademark name trademark pentium to their fifth-generation microprocessors.This architecture has been expanded twice to accommodate a larger word size.
In 1985, Intel announced the 386-generation design that replaces the 32-bit design of 286 16-bit generation.32-bit architecture is called x86-32 or IA-32 (short for Intel Architecture, 32-bit). Then in 2003, AMD introduced the Athlon 64, which apply for further development of this architecture to the 64-bit architecture, known by several terms x86-64, AMD64 (AMD), EM64T or IA-32e (Intel), and x64 (Microsoft).
To view the historical development of electronic components can be seen below:
Optical mouse uses a red LED as a replacement ball mouse. Light from this LED will be reflected by the surface of the table / pedestal to the sensor CMOS (Complimentary Metal Oxide Semi-konductor). The sensor then sends a picture of the surface to the Digital Signal Processor (DSP).
DSP will analyze the images before and determine the distance obscuring the mouse which is then sent to computer. Based on these data, the computer will shift the mouse cursor position on screen. If now there is kind of an optical mouse that can run on any base surface, first optical mouse to be run at a special mouse pad that has a pattern of lines of this box which will break the pattern of light reflection LED.Based on LED flame-off, the computer will know the distance obscuring the mouse. But, mouse type is more difficult to use and can not be used without special mouse pad.
Advantages compared to optical mouse mouse optimekanik:
1. No part to be moved, so there is no possibility of failure of the round.
2. Because fully closed, not allowing dust into the mouse.
Resolution tracking softer light so that movement of the mouse cursor on the screen is also more subtle.
