week 7
11th March 2014
Was the day of our presentation, we started describing the 3 sensors for the input we are going to use. searching on them made me learn many things like the way they performs there functions and how they work as starting from the very first sensor which is
VSS (Vehicle Speed Sensor): As we know seat belt is one of the most safest part when it comes to be safety in vehicle, and all the vehicles in automotive industry use it.By the safety belt designers in recent years a Reed Switch sensor has been discovered as being the most reliable and best way to detect the engagement of seat belt.
Features/Functions:

Was the day of our presentation, we started describing the 3 sensors for the input we are going to use. searching on them made me learn many things like the way they performs there functions and how they work as starting from the very first sensor which is
VSS (Vehicle Speed Sensor): As we know seat belt is one of the most safest part when it comes to be safety in vehicle, and all the vehicles in automotive industry use it.By the safety belt designers in recent years a Reed Switch sensor has been discovered as being the most reliable and best way to detect the engagement of seat belt.
Features/Functions:
•Can activate & control the switching
function from the one side of the seat belt buckle.
•Is designed to handle the high shock
environments
•Can be operated in dirty environments
•Is hermetically sealed
•Lots of reliable switching operation
•Reliable switching
•Dynamically tested contacts
> Second sensors which i searched n presented was the SOS
SOS(Seat Occupany Sensor): The
occupancy sensor consist of the flexible sensor mat, which in inserted or
installed into the vehicle seats.The
mat consists of two sandwiched carriers sheets held together.
•Increase
pressure on the mat will cause the electrical resistance change, which informs
the system that the seat is occupied or not.
•The
vacant or occupied seat will correspond to an open or short circuit.
•The
occupancy on the seat is only detected for higher weight depending on the specs
mostly 40 kg.
•The
occupant detection technology will not affected by the
•
Weight, seat belt tension, or movement
of the passenger.
•Furthermore,
the system will not be triggered by inanimate objects placed on the seat.
FEATURES OF SOS:
·Senses
immediate presence of pressure applied to pad.
·Bend
Sensor / Potentiometer.
·Small
size is ideal for embedded applications.
·User
defined thresholds for alerts and notifications
>And 3rd sensor was the VSS(vehicle speed sensor which was performed by my group mate)
