3 D ICs

Added on: February 16th, 2012 by Afsal Meerankutty 1 Comment

The unprecedented growth of the computer and the Information technology industry is demanding Very Large Scale Integrated (VLSI) circuits with increasing functionality and performance at minimum cost and power dissipation. VLSI circuits are being aggressively scaled to meet this Demand, which in turn has some serious problems for the semiconductor industry.

Additionally heterogeneous integration of different technologies in one single chip (SoC) is becoming increasingly desirable, for which planar (2-D) ICs may not be suitable.

3-D ICs are an attractive chip architecture that can alleviate the interconnect related problems such as delay and power dissipation and can also facilitate integration of heterogeneous technologies in one chip (SoC). The multi-layer chip industry opens up a whole new world of design. With the Introduction of 3-D ICs, the world of chips may never look the same again.

Animatronics

Added on: February 9th, 2012 by Afsal Meerankutty No Comments

Animatronics is a cross between animation and electronics. Basically, an animatronic is a mechanized puppet. It may be preprogrammed or remotely controlled. An abbreviated term originally coined by Walt Disney as “Audio-Animatronics” ( used to describe his mechanized characters ) ,can actually be seen in various forms as far back as Leonardo-Da-Vinci’s Automata Lion ,( theoretically built to present lillies to the King of France during one of his Visits ),and has now developed as a career which may require combined talent in Mechanical Engineering , Sculpting / Casting , Control Technologies , Electrical / Electronic , Airbrushing , Radio-Control.

Long before digital effects appeared, animatronics were making cinematic history. The scare generated by the Great White coming out of the water in “Jaws” and the tender otherworldliness of “E.T.” were its outcomes. The Jurassic Park series combined digital effects with animatronics.

It is possible for us to build our own animatronics by making use of ready-made animatronic kits provided by companies such as Mister Computers.

Airborne Internet

Added on: February 6th, 2012 by Afsal Meerankutty 2 Comments

The Airborne Internet is network in which all nodes would be located in aircraft. The network is intended for use in aviation communications, navigation, and surveillance (CNS) and would also be useful to businesses, private Internet users, and military. In time of war, for example, an airborne network might enable military planes to operate without the need for a communications infrastructure on the ground. Such a network could also allow civilian planes to continually monitor each other’s positions and flight paths.

Airborne Internet is network will serve tens of thousands of subscribers within a super-metropolitan area, by offering ubiquitous access throughout the networkâ„¢s signal “footprint”. The aircrafts will carry the “hub” of a wireless network having a star topology. The aircrafts will fly in shifts to provide continuous service, 24 hour per day by 7 days per week, with an overall system reliability of 99.9% or greater. At least three different methods have been proposed for putting communication nodes aloft. The first method would employ manned aircraft, the second method would use unmanned aircraft, and the third method would use blimps. The nodes would provide air-to-air, surface-to-air, and surface-to-surface communications. The aircraft or blimps would fly at altitudes of around 16 km, and would cover regions of about 40 mi (64 mi) in radius. Any subscriber within this region will be able to access the networkâ„¢s ubiquitous multi-gigabit per second “bit cloud” upon demand. what the airborne internet will do is provide an infrastructure that can reach areas that don’t have broadband cables & wires. Data transfer rates would be on the order of several gigagabits per second, comparable to those of high-speed cable modem connections. Network users could communicate directly with other users, and indirectly with conventional Internet users through surface-based nodes.

Like the Internet, the Airborne Network would use TCP/IP as the set of protocols for specifying network addresses and ensuring message packets arrive. This technology is also called High Altitude Long Operation (HALO) The concept of the Airborne Internet was first proposed at NASA Langley Research Center’s Small Aircraft Transportation System (SATS) Planning Conference in 1999.
