Passive Optical Networks

-
A passive optical network is a point-to-multi-point architecture for delivering last-mile connectivity without any active components in the distribution network. A Passive Optical Network consists of:
   1. An optical line terminator (OLT) located at the Central Office(CO)
   2.Set of associated optical network units-ONUs, (or optical network terminals-ONTs) located at the customer’s premise.Optical distribution network (ODN) comprised of fibers an passive splitters or couplers for connectivity Information Flows. Check out this video

AUDIO SPOTLIGHTING

INTRODUCTION n   Audio spot lighting is a very recent technology that creates focused beams of sound similar to light beams coming out of a flashlight. By ‘shining’ sound to one location, specific listeners can be targeted with sound without others nearby hearing it, ie to focus sound into a coherent and highly directional beam. It uses a combination of non-linear acoustics and some fancy mathematics. But it is real and is fine to knock the socks of any conventional loud speaker. n   The Audio Spotlight & Hyper Sonic Sound Technology (developed by American Technology Corporation), uses ultrasonic energy to create extremely narrow beams of sound that behave like beams of light. Audio spotlighting exploits the property of non-linearity of air. When inaudible ultrasound pulses are fired into the air, it spontaneously converts the inaudible ultrasound into audible sound tones, hence proved that as with water, sound propagation in air is just as non-linear, and can be calculated math

Electronic Reconnaissance: Reconnaissance aims to give to field players, at a tactical level, the information they need: Where are (and where will be) the targets, what are their defenses, what military means to use, what kind of weapon is the best suited, when to conduct the attack, etc. Due to short reaction time in Air Defense, this task is generally carried out directly by the AEW system. In fact in some cases the AEW platform is a C3I system itself that controls the fighters in real time. For ground targets, due to slower evolution of the situation and to a more complex environment (collateral damage avoidance, mask), a specific mission is needed. This mission uses SAR/MTI systems either fitted in POD carried by a manned aircraft (business jet or fighter), or carried by an unmanned vehicle (UAV). The main objective of these missions is to re-acquire the targets (in case they are moved as Ballistic Missile Launchers), and to identify and locate them accurately. Once again fusion

INTERFACING OF EEPROM with 8051

7.1 Introduction As we know, ROM is a memory that does not lost its contents when the power is turned off. For this reason ROM is also called Non-Volatile Memory. There are different types of ROM such as PROM, EPROM, EEPROM, Flash EPROM and Mask ROM. In which PROM refers to the Kind of ROM that the user can burn information into. PROM is a user programmable memory. PROM is referred to as OTP (One time programmable). EPROM was invented to allow making changes in the contents of PROM after it is burned. In short, one can program the memory chip and erase it thousands of time. This is especially necessary during development of microcontroller based project. EEPROM is electrically erasable programmable ROM. EEPROM has several advantages over EPROM. EEPROM does not require external eraser and programming device. Flash EPROM has become a popular user programmable memory chip. The reason behind that is the eraser of entire content takes less than a second that why it is named Flash memory. Wh
