What is Brain Fingerprinting?

Brain Fingerprinting is designed to determine whether an individual recognizes specific information related to an event or activity by measuring electrical brain wave responses to words, phrases, or pictures presented on a computer screen.  The technique can be applied only in situations where investigators have a sufficient amount of specific information about an event or activity that would be known only to the perpetrator and investigator.  In this respect, Brain Fingerprinting is considered a type of Guilty Knowledge Test, where the "guilty" party is expected to react strongly to the relevant detail of the event of activity.

Existing (polygraph) procedures for assessing the validity of a suspect's "guilty" knowledge rely on measurement of autonomic arousal (e.g., palm sweating and heart rate), while Brain Fingerprinting measures electrical brain activity via a fitted headband containing special sensors.  Brain Fingerprinting is said to be more accurate in detecting "guilty" knowledge distinct from the false positives of traditional polygraph methods, but this is hotly disputed by specialized researchers.

What is HYPER TRANSPORT TECHNOLOGY ?

Hyper Transport technology is a very fast, low latency,  point-to-point link used for inter-connecting integrated circuits on board. Hyper Transport, previously codenamed as Lightning Data Transport (LDT), provides the bandwidth and flexibility critical for today's networking and computing platforms while retaining the fundamental programming model of PCI. Hyper Transport was invented by AMD and perfected with the help of several partners throughout the industry.

           

                        Hyper Transport was designed to support both CPU-to-CPU communications as well as CPU-to-I/O transfers, thus, it features very low latency.  It provides up to 22.4 Gigabyte/second aggregate CPU to I/O or CPU  to  CPU  bandwidth in a highly efficient  chip-to-chip technology that replaces existing complex multi-level buses .Using enhanced 1.2 volt LVDS signaling reduces signal noise, using  non-multiplexed lines cuts down on signal activity and using dual-data rate clocks lowers clock rates while increasing data throughput. . It employs a packet-based data protocol to eliminate many sideband (control and command) signals and supports asymmetric, variable width data paths.

SMART DUST and its Applications

The smart dust mote consists of a micro controller which determines the task performed by the micro controller and the amount of power to be given to various components of the smart dust as energy conservation is one of the important issues in these motes
                           The microcontroller in the smart dust gets reading from one of the sensors processes it and stores it in the memory .it often switches on its optical receivers see if anyone is trying  to communicate  .the communication includes information about the task to be performed by the mote which could even change the behavior of the mote by giving new program code .to transmit a data to the centre station or another mote the mote uses the corner cube retro reflector or laser beam .
Smart Dust remain suspended in the air for hours, the air currents can also move them in the direction of flow. It is very hard to detect the presence of the Smart Dust and it is even harder to get rid of them once deployed. Moreover it does not cost much so can be densely deployed. Due to the above-mentioned features, Smart Dust can be used in varied application fields. These are as follows:
1)    Environmental protection (identification and monitoring of pollution).
2)    Habitat monitoring (observing the behavior of the animals in there natural habitat).
3)    Military application (monitoring activities in inaccessible areas, accompany soldiers and alert them to any poisons or dangerous biological substances in the air).
4)    Indoor/Outdoor Environmental Monitoring
5)    Security and Tracking
6)    Health and Wellness Monitoring (enter human bodies and check for physiological problems)
7)    Power Monitoring
8)    Inventory Location Awareness
9)    Factory and Process Automation
10)    Seismic and Structural Monitoring
11)    Monitor traffic and redirecting it
12)    Virtual keyboard Glue a dust mote on each of your fingernails. Accelerometers will sense the orientation and motion of each of your fingertips, and talk to the computer in your watch.

How Lie Detectors Works?

When a person takes a polygraph test, four to six sensors are attached to him. A polygraph is a machine in which the multiple ("poly") signals from the sensors are recorded on a single strip of moving paper ("graph"). The sensors usually record:
     The person's breathing rate
     The person's pulse
     The person's blood pressure
     The person's perspiration
Sometimes a polygraph will also record things like arm and leg movement.
When the polygraph test starts, the questioner asks three or four simple questions to establish the norms for the person's signals. Then the real questions being tested by the polygraph are asked. Throughout questioning, all of the person's signals are recorded on the moving paper.
Both during and after the test, a polygraph examiner can look at the graphs and can see whether the vital signs changed significantly on any of the questions. In general, a significant change (such as a faster heart rate, higher blood pressure, increased perspiration) indicates that the person is lying.
When a well-trained examiner uses a polygraph, he or she can detect lying with high accuracy. However, because the examiner's interpretation is subjective and because different people react differently to lying, a polygraph test is not perfect and can be fooled.

Introduction to Polygraph Machine

A polygraph (popularly referred to as a lie detector) is an instrument that measures and records several physiological responses such as blood pressure, pulse, respiration, breathing rhythms, body temperature and skin conductivity while the subject is asked and answers a series of questions, on the theory that false answers will produce distinctive measurements. The polygraph measures physiological changes caused by the sympathetic nervous system during questioning. Within the US federal government, a polygraph examination is also referred to as a psycho physiological detection of deception (PDD) examination.


Polygraphs are in some countries used as an interrogation tool with criminal suspects or candidates for sensitive public or private sector employment. The use and effectiveness of the polygraph is controversial, with the manner of its use and its validity subject to increasing criticism.

Global Positioning Systems (GPS)

Global Positioning Systems (GPS) are space-based radio positioning systems that provide 24 hour three-dimensional position, velocity and time information to suitably equipped users anywhere on or near the surface of the Earth (and sometimes off the earth). Global Navigation Satellite Systems (GNSS) are extended GPS systems, providing users with sufficient accuracy and integrity information to be useable for critical navigation applications. The NAVSTAR system, operated by the U.S. Department of Defense, is the first GPS system widely available to civilian users. The Russian GPS system, GLONASS, is similar in operation and may prove complimentary to the NAVSTAR system.

These systems promise radical improvements to many systems that impact all people. By combining GPS with current and future computer mapping techniques, we will be better able to identify and manage our natural resources. Intelligent vehicle location and navigation systems will let us avoid congested freeways and find more efficient routes to our destinations, saving millions of dollars in gasoline and tons of air pollution. Travel abord ships and aircraft will be safer in all weather conditions. Businesses with large amounts of outside plant (railroads, utilities) will be able to manage their resources more efficiently, reducing consumer costs. 

 

GPS, which stands for Global Positioning System, is a radio navigation system that allows land, sea, and airborne users to determine their exact location, velocity, and time 24 hours a day, in all weather conditions, anywhere in the world. The capabilities of today’s system render other well-known navigation and positioning “technologies”—namely the magnetic compass, the sextant, the chronometer, and radio-based devices—impractical and obsolete. GPS is used to support a broad range of military, commercial, and consumer applications.

24 GPS satellites (21 active, 3 spare) are in orbit at 10,600 miles above the earth. The satellites are spaced so that from any point on earth, four satellites will be above the horizon. Each satellite contains a computer, an atomic clock, and a radio. With an understanding of its own orbit and the clock, the satellite continually broadcasts its changing position and time. (Once a day, each satellite checks its own sense of time and position with a ground station and makes any minor correction.) On the ground, any GPS receiver contains a computer that "triangulates" its own position by getting bearings from three of the four satellites. The result is provided in the form of a geographic position - longitude and latitude - to, for most receivers, within a few meters.

If the receiver is also equipped with a display screen that shows a map, the position can be shown on the map. If a fourth satellite can be received, the receiver/computer can figure out the altitude as well as the geographic position. If you are moving, your receiver may also be able to calculate your speed and direction of travel and give you estimated times of arrival to specified destinations. Some specialized GPS receivers can also store data for use in Geographic Information Systems (GIS) and map making.
