Q

fundamental rate in
cycles per second (measured in hertz, kilohertz, megahertz or
gigahertz) for the frequency of the clock in any synchronous circuit.
A single clock cycle (typically shorter than a nanosecond in modern
non-embedded microprocessors) toggles between a logical zero and
a logical one state.

Q

By modern standards, both storage options seem pretty low. That’s
for a reason, of course. We take plenty of pictures and videos, mobile
games and apps have gotten bigger, and we save as many memes
as possible for later use.

Q

The symbols that follow IP - IP67, for example, or IPX7 indicate the
level of protection that’s provided. You’ll often see these ratings in
product advertising, on the retail box, and quoted in product reviews
including TechHive’s.

A

INGRESION PROTECTION

17
Q

The first number references the size of foreign objects that will be rejected, and the second
number rates the item’s resistance to liquid ingress.

A

NUMEROLOGY

18
Q

INGRESS PROTECTION FROM FOREIGN OBJECTS

A

Protected against objects larger than 50 mm (2 inches)
2: Protected against objects larger than 12.5 mm (0.5 inches)
3: Protected against objects larger than 2.5 mm (0.1 inches)
4: Protected against objects larger than 1 mm (0.04 inches)
5: Keeps enough dust out to prevent failure
6: Dustproof (no ingress)
X: Not tested. You’ll see this if the device was tested for liquids, but not solids; e.g., IPX7.

19
Q

INGRESS PROTECTION FROM FOREIGN LIQUID

A

Protected from vertical water drops (normal rain)
2: Protected from vertical water drops when device is angled upwards 15 degrees
3: Protected against water sprayed at an angle up to 60 degrees on either side of vertical.
4: Protected against water sprayed from any direction shall have no armful effects.
5: Protected against water projected in jets from any direction.
6: Protected against water projected in powerful jets from any direction
7: Can withstand immersion in up to one meter (approximately 3.3 feet) of water for 30 minutes.
8: Can withstand immersion in up to three meters (approximately 9.8 feet) of water for an
specified amount of time agreed upon with the IEC.
X: Not tested. We’ve yet to see this for reasons we’ll discuss below.

Q

IP RATINGS UNCOMMON TO CONSUMER
ELECTRONICS

A

A. Protects the back of the user’s hand from access to hazardous parts.
B. Protects the user’s fingers from access to hazardous parts.
C. Protects tools from contact with hazardous parts
D. Protects wire from contact with hazardous parts.
And
H. High-voltage device
M. Motion was induced during liquid tests
S. No motion was induced during liquid tests (device was static)
W. Weather conditions are stated

21
Q

This has both electronics, microelectronics, and micromechanical
modules inside. These use gyroscopes sensor information as well to
make more precision, information, and data.

A

ACCELEROMETER

22
Q

MEMS

A

Micro Electro Mechanical System sensor.

23
Q

This measures change in orientation and angular velocity. Some
sensor types include Microchip Packaged MEMS gyroscopes, this is
the commonly one that is in smartphones and smart watches.

A

GYROSCOPES

24
Q

This is an optical infrared light sensor technology and the operation
mechanism looks like this, where infrared light is absorbed by blood
and that is measured. Qe look at the infrared light that is being
absorbed and when it becomes darker, that is most likely because the
blood flow amount has increased and that is when a heart pulse is
done.

A

HEART RATE SENSOR

25
Q

used to measure atmospheric pressure, it is used in meteorology, as
well as atmospheric sensing. The atmospheric pressure is used in altitude
estimations. We have barometers and pressure altimeters, and these two are
slightly different, but their core technology is actually the same.

A

BAROMETER

26
Q

It has a seamless interface such that the surface becomes seamless
in its overall shape. In addition, it provides a very smooth luxurious
field. This is why it is perfect for smartphones, and that is why
shatterproof glass is commonly used.

A

SHATTERPROOF GLASS

27
Q

a specialized toughened shatter proof glass, that is
scratch resistant. It is there to prevent deep scratches

A

GORILLA GLASS

28
Q

this is used on iPhones. The physical property of
a molecule that is repelled from oil, this means oleophobic means
fear of oil. This is used on smartphones surfaces for fingerprint-
resistance and anti-smudging.

A

OLEOPHOBIC COATING

29
Q

Q

this is a thin-film-display technology
that uses organic compounds from the electro luminescent material.
