The face recognition software first take a photo of the face. Then, it compares the facial features from the photo
and the photo from the passport. e.g. the distance between the eyebrows if they match, the person is allowed to go.
Charged Couple Device is made of thousands of light sensitive elements, which produces and electric
charge when light falls on it. This means that the image is converted into electronic form.
Computed Tomography scanners build 3D solid objects by building up with thin slices of an object.
Magnetic Resonance Imaging scanner uses electromagnetic waves to scan.

A crystal is placed at the back of the ink resevor
the crystal is given an electric charged then it vibrates
the vibration causes the ink to be ejected on the paper
more ink is drawn for further printing
Better colour accuracy
Iink cost alot
produce solid image layers by layers
uses inkjet technology to print the layers by moving the print head left to right and up to down
uses two passes for each layers, first layer spray dry power then second layer spray glue
fashion and art
prosthetic limbs
precision reconstructive surgery
Brighter colour
consume less power
Much Thinner
Organic Light emitting diode
Flexible
Better color depth

Anti-Lock Breaking System
The sensors detect the pressure that has been touched by an intruder. The pressure value is sent out through ADC to the
microprocessor.
The microprocessor checks the value if it is in range.
if it is in the stored values no actions are taken.
If the pressure is outside the stored values, the microprocessor send out a signal through DAC to alarm and flash lights
