Brain-Machine Interface Technology

Robots can be controlled by just thinking. Whatever a person will think the robot will do that. Honda developed this technology and named it as Brain-Machine Interface. Here's the test of that machine in the video.

An unbelievable technology "Table-saw stops itself when touches finger"

There is about 60,000 medical treated accidents on table-saw every year that 3000 people take the finger off by 10 a day.


Steve Gass the pioneer of a table-saw which stops itself in some micro seconds when it comes in contact with the finger. And he named it as Saw-stop. He wanted to bring that accidents figure to zero. So he designed a system which can tell the difference between wood and finger.


When you are cutting wood and if you accidentally run your hand onto the blade it will stop so quickly and you can take your fingers off the blade. The blade is a acceptor it detects the electrical conductivity. A piece of wood is not very conductive so the saw goes right through it and a saw to your wet finger is conductive. It is like a touch device, there is an electrical signal on it which conducts that signal in human body, human body absorbs that signal that triggers the system and portion of machinery at the back of the blade helps the blade to stop in a fraction of second.

The blade rotates at 5000rpm and this system stops it in 1/1000 of a second and saves the finger which is something very hard to believe. By doing this action machine does not feel happy, it is something like you are driving a car 1000miles/hr and it hits the wall. By doing this action the machine is officially trashed and it costs you a $50 but in replacement of saving your finger.


This is the unbelievable table-saw machine called saw-stop:

Amazing new technology "Pen with a hidden cam"

Amazing new technology "Pen with a hidden cam". This pen is made by Japan, it has a hidden cam in it. Actually it looks like a pen but at the top of it there's round camera. By clipping its top up the camera turns on and can capture pictures and people's footage. There are buttons available on the pen to control the camera of changing its modes.
Now it is very easy to use camera in class and take teacher's pictures :D and put it on Facebook and get thousands of comments on that picture. Office workers have to be careful now because anyone with this pen can take your picture and show it to your boss to make you in trouble.

This is really an amazing technology not only at school and office level but at higher level for example in military actions etc

8051 C Programming

8051 C language is an often-preferred choice when the complexity of a program increases considerably. 8051 C language is an alternative to the assembly language programming. The choice of which to use is entirely up to you, the programmer. Factors that commonly influence such a decision are the desired speed, code size and ease of programming. Since the intent of this section is to present the basics of programming the 8051 in C.

Advantages and disadvantages of 8051 C

The advantages of programming the 8051 in C as compared to assembly are:
  • Offers all the benefits of high-level, structured programming languages such as C, including the ease of writing subroutines.
  • Often relieves the programmer of the hardware details that the compiler handles on behalf of the programmer.
  • Easier to write, especially for large and complex programs.
  • Produces more readable program source codes.
Nevertheless, 8051 C, being very similar to the conventional C language, also suffers from the following disadvantages:
  • Possesses the disadvantages of high-level, structured programming languages
  • Generally generates larger machine codes
  • Programmer has less control and less ability to directly interact with the hardware

Atif Aslam's First Movie As An Actor

"Bol" is Atif Aslam's first movie as an actor, it is directed by Shoaib Mansoor the only leading director from Pakistan's film industry in this type of crises situation. Here's the song "hona tha pyar" from the this movie. It is really an awesome song.

Enzo Ferrari and its features

Company founder Enzo Ferrari always felt that
design of the road cars should stem from the
racers. Therefore, it was entirely logical that the
company's latest creation should bear his name.
The Enzo, built in a limited run of 399, is an
outstanding expression of the concept of extreme
sportiness, developed for road use, yet
epitomizing the most advanced concepts of 
Formula 1 racing technology.

Enzo Ferrari 


Ferrari set out to develop the Enzo as an
integrated system designed for extreme
performance, in which even the limits of
the performance achievable by the driver
were enhanced, thanks to a man-machine
interface typical of Formula 1.

Never before has style been derived so
directly from function as in this model.
Pininfarina wanted to create an uncompromising
car that would break away from the 
approach used for the GTO, F40 and F50
that preceded it, to develop a new formal
language that looked to the future.
The engineers tried to create visual links
with the world of Formula 1, to which the
Enzo owes its technology, while highlighting
its compactness and lightness. The result
is a complex, sculpted form.

The use of advanced composite materials
for the bodywork, with parts made of
sandwich panels of carbon fibre and
Nomex, allowed the designer to structure
the bodyshell while keeping the weight to
a minimum, and creating "extreme" stylistic
forms.

The front, with its two air intakes for the
radiators and a raised central section, is
an interpretation of the Formula 1 front
section with a small pointed, raised nose
and air-intakes under the spoilers in a
gull-wing effect. The sides, also benefit
from the use of composites, shaped to
optimize air-flow with respect to internal
fluid dynamics. The large spoiler has
been eliminated from the car's rear
section which now boasts small aerodynamic
appendages and very efficient ground effects.


Aerodynamics

In developing the Enzo, Ferrari set 
itself two pure performance targets
which would represent a milestone for
ultra-fast cars: to increase the grip
limit in medium-fast bends by increasing
downforce (lateral dynamics,) while 
maintaining a very high top speed, over
350 km/h (longitudinal dynamics.)

This meant that different aerodynamic
configurations with contrasting 
characteristics had to coexist on
the same car. In racing cars, this 
problem is solved by developing
wings and special aerodynamic 
accessories for each circuit. But
in the case of the Enzo, for which
the various targets had to coexist 
in a single aerodynamic configuration,
a concept of active, integrated 
aerodynamics was developed.

The high downforce configuration
was obtained with a basic aerodynamic
set-up developed on the basis of
contemporary concepts for the
definition of covered-wheel racing
cars combined with the expertise
of Ferrari Gestione Sportiva.

The optimal aerodynamic set-up
is kept stable by special elastic
features of the car's engineering
and by active aerodynamic control.

As the speed increases from
low-medium to high-very high, 
the engineering ensures that the
car takes on the optimal 
aerodynamic set-up (maximum
downforce obtained with an 
optimal load distribution) by 
varying the rigidity on the basis
of ground clearance. As the 
speed climbs even higher, this set-up
is maintained by the combined 
action of the flexible mechanical 
components and by active control of
the spoilers. At very high speeds,
the actively controlled spoilers 
(front and rear fins) limit the 
maximum vertical load, thus making
it possible to keep the car above a set
minimum ground clearance. On the Enzo,
the aerodynamic load and balance can be
modified on the road by means of a
pair of flaps positioned in the front slides
and a rear spoiler.


Vehicle Control System

The Enzo project is the first example
of the complete integration of the
vehicle control systems. Engine,
gearbox, suspension, ABS/ASR, and
aerodynamics all interact to optimise the
vehicle's performance and safety.
This presupposes an innovative approach
to the design of the control system architecture,
andto the development and fine-tuning of the
subsystem-son the car. It was made possible by
the collaboration and specialist skills of
Gestione Sportiva, and performance of each
system was designed to enhance that of the
entire car. The target when defining
the control strategies of each subsystem
was therefore the optimal behaviour of the car.
The subsystems that interact are: the engine,

gearbox, suspension, aerodynamics, and
the ABS/ASR system. The large number
of systems made it necessary to use special
sensors. Management of the sensors is
divided between the various control systems,
each of which shares the relevant information
with the rest of the system. The way the
systems interact depends on the driving
modes that the driver can choose from.

The Enzo offers several set-ups: Sport, Race,
No ASR.

Electrical System

The architecture of the F140 project was
designed to minimize the section of the cables
that link the utilities positioned on the steering
wheel, the steering column, the onboard
instruments,and the rest of the car.To achieve
this goal, the architecture was based on a
high speed communication line which links
several different control units which pick up
the signals "in the surrounding environment".
These signals are transformed into information
which can then only beexchanged through the
communication line.

Engine

The engine of the Enzo Ferrari (which is
known by its project number F140) is a
12-cylinder aspirated unit in a 65° V, a cylinder
capacity of 5,998 cc, with a completely new
design that draws on experience gained in
Formula 1, and hasa number of unique
technical features. Thecylinder head design
reveals its Formula 1 origins: the
"pentroof-type" combustion chamber,
with four valves per cylinder, plus inlet
and exhaust ducts designed to maximise
the exhaust coefficients and combustion
speed.

The cylinder case is built of aluminum with
press-fitted sleeves lined with nicasil


The timing gear features four overhead camshafts,
direct valve control, and hydraulic tappets. It is
completely chain-driven, with central transmission
on triple gearing.The timing of the inlet and
exhaust manifolds is continuously variable, thanks
to the intervention of four variable advances
activated by the engine control unit throughout the
operating range via a high pressure hydraulic system,
with the goal oflowering the noise and enhancing
versatility.

The lubrication sump is of the F1 wrapround type,
incorporating the main bearings and a specific oil
recovery circuit to increase efficiency.

The variable geometry inlet manifold is also borrowed
from Formula 1, with a system of small telescopic
derivation cones, combined on this V12 application,
with variable timing gear with a continuously variable
advance on the four camshafts and a high pressure
control unit.

Electronic engine management is provided on each
row of cylinders by a Bosch Motronic ME7 unit which
controls the PFI multiple injection system, the
drive-by-wire throttle valve, and the single coils on
each spark plug.Six knock sensors mounted on
he crankcase guarantee knock control.

The performance goals of the new V12 have been
met in full, in order to supply a unique blend of very
high power, generous torque from low speeds and
versatility. In spite of the large capacity of the engine,
the applications derived most directly from
Ferrari's Formula 1 experiencehave made it possible
to keep the specific power of theengine at an
extremely high 110 bhp/litre.

F1 Transmission and Gearbox

In the F140 project, the rear gearbox is coupled
directly tothe engine by an element that
incorporates the engine oiltank, the bevel
gear pair, and the self-locking differential.
In line with the car's performance targets,
the gearboxunit was developed only in a
Formula 1 version. Gearchanges
are entrusted entirely to an electrohydraulic
system which activates the gearbox and
clutch. Gearchange control is managed
electronically and activatedby paddles
positioned behind the steering wheel,
modifying engine torque and vehicle dynamics.

The project was designed for extremely
sporty performance and adopts triple
cone synchronisers on all six speeds.
Lubrication is forced, with a large pump
and lower oil level to minimise losses
due to ventilation/shaking.The architecture
with three bearings guaranteesoptimal
gear train coupling even at high torque.
The twin plate clutch with aluminium
housing and a diameter of 215 mm
also speeds up engine dynamics and
synchronisation.

The number one goal of the Enzo project
was to cut gear change times (down to
150 milliseconds) in the interests of extremely
sporty use. The F1 gearlevers are made
of carbon, with an optimised shape
and size, and they have been made
symmetrical by transferring the direction
indicator controls to the steering
wheel spokes. The gear change pushbuttons
are mounted on the steering wheel, as are the
two different gear change
modes, Sport and Race, as well as the reverse
gear selector button.

Each of these modes comes with its
own integrated software controlling
damping and traction control systems
(ASR.) In RACE mode and with ASR
disengaged, the Launch Control strategy
borrowed from Formula 1 is alsoavailable,
allowing the driver to start off at topspeed
in good grip conditions. The driver keeps
the brake pedal down while he uses the
accelerator pedal tochoose the engine
speed at which he wishes to set off.
When he releases the brake pedal, the
clutch closes rapidly while torque control
is left to the driver.

The system fine-tuned by Ferrari for its
Formula 1 transmission envisages a special
multiple-telltale at the centre of the main
instrument panel which keeps the driver
constantly informed about the state
of the system and the speed engaged.


Chassis

The chassis was built entirely of carbon fibre and
aluminium honeycomb sandwich panels, which 
made it possible to meet demands for outstanding 
rigidity, lightness and safety. In order to pass the
offset collision tests required by the latest safety
standards (56 km/h impact), highly sophisticated
CAE methodologies were adopted to optimise the
composite structures, to identify the optimal body-shell
structure, and to maximise the contribution
of the reinforcement skin, where it is needed to
support the basic panelling. The final result already
meets the stricter future standards which will raise
the collision speed to 60 km/h.Respect for the
styling and access targets (door solution
with impact on the roof of the chassis) and the
goal of passing 64 km/h offset collision tests
with a view to further evolution of the requirements 
(extremely demanding in structural terms as a result
of the 30 % increase in kinetic energy to be
dissipated compared to previous collision standards),
required complex planning of the tooling and the
manufacturing methods.
The use of CAE optimisation methodologies was
extended to the engine support frame, and 
particularly to the distribution of thicknesses
in the suspension casting. In line with the
work done for the bodyshell,a specific
analysis set-up made it possible to identify
the best weight-performance trade-off, 
supplying exact indications for the 
distribution of casting thicknesses.

Experiments confirmed the validity of the
solutions chosen: torsional rigidity proved
to be higher than the project target and to 
correspond to the values calculated,
while all the homologation collisions gave
a positive result from the start.

These results are all the more significant
if we considerthat the chassis weight
had also been decreased considerably
to 92 kg (compared to the 102 kg of the
composite chassisof the earlier F50).

Suspension and Wheels

The Enzo has independent front and
rear suspensionwith jointed double
wishbones, and antidive-anti-squat geometries
to limit pitching during the transfer of longitudinal
loads. The front uspension, which is push-rod 
in type with an opposed damper, also
incorporates a lift to increase
ground clearance during parking maneuvers.
The rear suspension was designed to adapt 
to the chassis, with the engine-gearbox-differential
assembly supported elastically, and a rear subframe.

Combined with this suspension layout, an 
adaptive set-up was adopted for the Enzo project,
based on a system of continuous control of the 
damping effect. The adoption of this system 
on the vehicle makes it possible to reconcile
handling requirements (i.e. roadholding, minimal
variation of the ground load) with the demands
of comfort(movement and acceleration of the
"shell", vibration transmitted to the driver),
without having to adopt passive solutions
(standard dampers) as a compromise.

In other words, electronic adaptation of the damping
effect makes it possible to use a damper setting
that is sufficiently comfortable in the car's basic
configuration ("Sport" setting), yet there is also a
setting that offers extra control in high
performance conditions ("Race" setting).


The system uses the unsprung weights (wheels
and suspension) to hold the sprung weight still (body)
but it also insulates theshell from impulses
transmitted to the wheels by the ground.
The system is actually made up of four sensors
(accelerometers) on the shell, two vertical wheel
sensors, one vehicle speedsensor and a brake switch.
The dampers are fitted with an internal proportional
valve governed by the control unit, allowing damping
to be modified instantly.

The braking torque control strategies (via ABS/ASR)
were specially developed on the basis of the installed
power and the optimisation of the braking system,
and achieved a satisfactorily convenient result in
terms of torque and braking pressure.

Although the Enzo project put the emphasis on
handling, because of the car's extreme connotations,
the adaptive set-up system employed meant that a
good level of comfortcould be obtained. Where the
wheel modules are concerned, single-bolt light
aluminium alloy wheels were chosen.The tyres
were developed specifically for the Enzo project
by Bridgestone and bear the exclusive name
"Bridgestone Potenza RE050 Scuderia".

In order to maximise running safety, the car is
equipped with a system that measures tyre
pressure throughspecial sensors inside the
wheel rims, near the inflation valve. These
sensors transmit a signal which is picked up
by the antennae behind the stone traps on
the bodyshell and linked to the control unit
of the pressure monitoring system, which
transmits thestate of the tyre pressure to
the instrument panel.

Braking System

The braking system developed for the car by
Brembo features brakes made of
carbo-ceramic material (CCM) used for the
first time on a Ferrari road car, although Ferrari
has been using them for many years on its
Formula 1 racing cars. This made it possible
to achieve outstanding results on the Enzo for
all braking performance parameters. The main
benefit required of this application was a decrease
in unsprung masses, which was made possible
by the significant reduction in the weight of the
brake discs (12.5 kg less than conventional brakes).
In addition to this, the entire braking system
was obviously designed for maximum
braking effectiveness and efficiency, in terms
of prompt braking, stopping distances, and
fade resistance. A further benefit of using
brake discs in composite material was achieved
in terms of improved reliability over time.

Interior

All of the main surfaces are made from unadorned
carbon fibre. The functional elements are hooked
onto a structural aluminium crossbeam. One of
the main goals for the interior of the Enzo was
to develop the concept of a facia and steering
wheel that could optimise the flow of information
and the way controls were activated by the driver,
to make the so-called man-machine interface
much more efficient.

One element that helped in this direction is the
completely new steering wheel, the upper part
of which is made of carbon and bevelled so as
not to limit external visibility. It contains a series
of LEDs which duplicate the telltales and the rev
counter, and the lower part has been optimized
to make more space for the driver.

Like a Formula 1 steering wheel, it also includes
a large number of controls (six) on either side,
linked to the main vehicle control functions:
vehicle lift, reverse, exclusion/re-engagement
ASR, integrated Sport/Race strategy, display
configuration.

The control panel is tailor-made for the driver and
includes technical features that are easily accessible
from the wheel grip, and a compact, mixed
analogue-digital instrument panel, in the shape
of a reconfigurable graphic screen.

The driver's seat is an essential part of the
driving position structure. A new racing seat
was developed, made of carbon fibre and
designed to give greater rigidity and to make
the driving sensation more precise, filtering
even the tiniest flexion in the seat system as
much as possible. The aim was to give the
Enzo driver the greatest possible awareness
of the car's behavior.

Seat inclination is adjusted by a double
Bowden lever system, and includes a lever
control on the seat cushion, the only system
of its kind in the field of fast sports car seats.
The driver can also adjust the squab-seat
combination to obtain a perfect driving posture.

Because the project only envisages a version
with the F1 gearbox, there are only two pedals
accelerator and brake) which were optimized
functionally and stylistically. There are numerous
settings, for a total of 16 different configurations.

Semester Project in Matlab (Dilation & Erosion)

DILATION:
The process of dilation here involves a structuring 
element of order 3*3 or any odd order, the values 
to each of its pixels is binary 1.the central pixel of
the structuring element imposes on each of the
pixel of the object or the image.if the value of the
center pixel of the structuring element and object
is the same i.e 1(one),it assigns all the overlapping
pixels the value of 1.that is it dilates the image or
the object.otherwise it moves to the next pixel.
For writing the code in Matlab for dilation, we need
to use 'if ' condition in this way:
If ((origin of structuring element) ==255) then make
all pixels 1 for whole range of structuring element.
This was our pseudo code for process of dilation.

EROSION:

The process of erosion here involves a structuring
 element of order 3*3.the values to each of its pixels
 is binary 1. the central pixel of the structuring
 element imposes on each of the pixel of the object
 or the image.If the value of the center pixel of the
 structuring element and all the pixels overlapping
 with the pixels of the object are the same i.e if
 they are 1,keep the pixel.otherwise move to the
 next pixel.
The pseudo code for erosion process is like this:
If((origin of structuring element) == 255
&& (whole range of structuring element) ==255*9) 
then center will remain equal to 1.

Wireless tracking technology RFID

RFID stands for radio frequency identification. It is used to generate a wireless communication of living or non living things with the controller device. RFID kit is like a controlling system and RFID tags are the source to generate communication between the object (to which RFID tag is attached) and the RFID controller kit. 


RFID is similar to bar code system but bar code system works on optical signal and RFID works on RF signal. RFID tags stores the data of the object and transmits it with the RF signal to the controller system according to the logic developed by the user. It is very useful in telecommunication field where the work is based on wireless sources.Many college/university projects have been made by using RFID kits such as door security system, avoid library books from stolen, attendance of teachers or students in class,patient management system, RFID based parking system etc
For any RFID system:
1. We need to have a transceiver to generate RF signal
2. An antenna is required to transfer that RF signal between transmitter and controller.
3. Transmitter is usually the RFID tag and controller is the RFID kit (microprocessor can also be attached to it).
An interesting thing about RFID in the field of medicines is that Kodak has filed this patient application for RFID tagged capsules that could be swallowed to track activity in a patient’s digestive system. The capsules would contain a tiny tracking chip which could be used to monitor a patient’s medication history, or to transmit other medical information to a nearby RF data collector. The pills would be designed to break down over time without harming the recipient.
Now the the information inside the human body can also be collected and worked out.
