Optical character recognition Optical character recognition is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo or from subtitle text superimposed on an image. It is widely used as a form of information entry from printed paper data records, whether passport documents, invoices, bank statements, computerised receipts, business cards, mail, printouts of static-data, or any suitable documentat

Transponder car key (August 2012) (Learn how and when to remove this template message) A transponder chip disarms a vehicle immobiliser when the car key is used to start the engine. The majority of keys to cars built after 1995 contain transponder chips. When the car key is turned in the ignition, the engine control unit (ECU) on the car sends an electronic message to the key, and it will allow the car to start only provided it receives the correct message back.

What is a transponder? If you are using a satellite receiver, you can go into the system test screens and see how well you are receiving all the transponders on a single satellite. Of course, some transponders will be spot beams so you won't get them at all. Transponder capacity To some extent, the number of channels on a transponder can vary. A whole transponder signal is sent at once from the uplink facility so if that facility has more advanced encoding equipment they may be able to fit more channels.

Passive optical network A passive optical network is a form of fiber-optic access network. In most cases, downstream signals are broadcast to all premises sharing multiple fibers.Encryption can prevent eavesdropping. Upstream signals are combined using a multiple access protocol, usually time division multiple access (TDMA).PON uses standard 802.3 Ethernet frames with symmetric 1 gigabit per second upstream and downstream rates. EPON is applicable for data-centric networks, as well as full-service voice, data and video networks. 10 Gbit/s EPON or 10G-EPON was ratified as an amendment IEEE 802.3av to IEEE 802.3.

Optical Fiber Cables Optical fiber cables are a technology that uses glass (or plastic) threads to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages onto light waves. ''A fiber-optic cable is made up of incredibly thin strands of glass or plastic known as optical fibers; one cable can have as few as two strands or as many as several hundred.

The fundamentals of optical light sources and transmission “Source aperture” describes the width of the transmitted light signal pulse. This characteristic is also related to the diameter of the optical fiber (the “waveguide”) that will optimally transmit the light pulses, which helps to explain why there are several types of optical fiber cabling systems available.

What are Optical Mark Reader documents used in? Optical Mark Reader (OMR) is kind of like the old version of bar-codes. Basically what is happening is you shine a light an an object, usually paper, and measure the amount of reflection of the light. As the mark passes under the reader, the reflected light changes. This change is picked up by the reader and turned into data for the rest of the system to interpret. Some mass mailing houses still use OMR to assemble the statements, although more and more are moving to bar codes.

Optical flow Optical flow sensors are also being used in robotics applications, primarily where there is a need to measure visual motion or relative motion between the robot and other objects in the vicinity of the robot.he concept of optical flow was introduced by the American psychologist James J. Gibson in the 1940s to describe the visual stimulus provided to animals moving through the world.

Transponder Basics Altitude reporting. The altitude-reporting capability of your transponder transmits your aircraft's PRESSURE ALTITUDE (rounded off to the nearest 100 feet) whenever it receives a Mode C interrogation and is switched to ALT mode.here's a new type of transponder called a Mode S transponder that is required for TCAS and may support datalink. A few years ago, the FAA tried to mandate that the fleet retire their Mode A/C transponders and upgrade to Mode S, but this move was strongly resisted by AOPA and other general aviation groups.

- E-ZPass® is an electronic-toll collection system that removes cash, coins and toll tickets from the toll-collection process. Instead, drivers open accounts with the Maryland Transportation Authority and pay tolls in advance by way of small electronic devices attached to their vehicles’ windshields. How does E-ZPass ® work? Your vehicle is equipped with a small electronic device called a transponder, which transmits information. This information is processed, and a toll is deducted automatically from your account as your vehicle passes through the toll lane.
