BlueTooth is a specification
for the use of low-power radio communications
to wirelessly link phones, computers and other
network devices over short distances. Bluetooth
technology was designed primarily to support
simple wireless networking of personal consumer
devices and peripherals, including cell phones,
PDAs, and wireless headsets. Wireless signals
transmitted with Bluetooth cover short distances,
typically up to 30 feet (10 meters).
Bluetooth devices generally communicate at
less than 1 Mbps and uses omnidirectionals
radio waves that can transmit through walls
and other non-metal barriers. Bluetooth transmits
in the unlicensed 2.4GHz band and uses a frequency
hopping spread spectrum technique that changes
its signal 1600 times per second.
Bluetooth technology requires specific hardware
and software, and for its development B52,
has joined the main producers worldwide. |

Thin Film Transistor-Liquid
Crystal Display is a variant of liquid
crystal display (LCD) which uses thin film
transistor (TFT) technology to improve image
quality. The concept lies in a special transistor
built with thin layers over metallic contacts,
where each layer activates one pixel. This
increase the quality and vision angle of the
image.
This type of transistor is almost immune to
radiation, less noisy and also more stable.
For these reasons it is ideal for our products. |

| USB FLASH DRIVES are NAND-type
flash memory data storage devices integrated
with a USB (universal serial bus) connector.
They are typically small, lightweight, removable
and rewritable. This type of memories better
resist the dust and scratches if they’re
compared with a CD. Nowadays you can find
on the market memories of 1,2,4,8 G B or more
(this is equal the capacity of 11 CDs) for
a reasonable price and for a product that
is rewritable. These devises have low consumption,
and they are very silent as they have non-mobiles
mechanic parts. Also they have a small size
which is a determinant factor when choosing
a portable devise. |
