Development of eCall for Malaysia's automotive industries
โRoad accidents are one of the most common
causes of death among Malaysian citizens. The common
problem when accident happened is drivers often have
inaccurate awareness of their location, especially on interurban
roads or abroad. There are also victims who are injured or
trapped and they may not be able to call emergency Call Centre.
The scenario may be worsen if there are no witnesses or passersby near the victims to assist them. In order to decrease the rate
of fatal accident in Malaysia, eCall system is proposed. The main
objective of this research is to develop eCall system that can
transmits a call to the public service answering point along with
certain vehicle related information using microcomputer, GSM
and GPS technologies. The eCall system is able to work
automatically or manually depends on the victimโs need. As
such, collision detection and voice communication algorithm has
been designed. For the collision detection, algorithm has been
developed based on the data acquired from gyroscope and
accelerometer. The location of incident has been identified using
GSM cell phone and GPS location capability. The device has a
corresponding infrastructure of Public Safety Answering Points
(PSAPs) for the voice communication to inform the emergency
emergency response unit about the accident, the level of
seriousness and the location of the incident. The eCall prototype
has successfully designed and developed. Experimental results
shown that the prototype is able to detect collision, identify the
GPS coordinates of the accident and able to transmit sound
wave from speaker to microphone, to be forwarded to the
emergency Call Centre
Low-cost remotely operated underwater vehicle for underwater observation purposes
This paper is about the development of a low-cost
remotely operated underwater vehicle (ROV) for the observation
of underwater environments without risking human life. The
overall safety feature focuses on protecting internal circuits from
being overloaded by any unexpected high current as well as
protecting battery from being over-discharged to prolong the
batteryโs life. The robot has internal sensor to measure the
battery voltage level along with its movement speed for safety
precautions. It has a camera that sent underwater visuals to the
users at the base station for underwater monitoring, observation,
and exploration purposes. Floatable ballasts that hold adjustable
volume of air are attached to the vehicle. The ROV has been
tested on several locations for performance analysis, data
collection, and navigation control; moreover, it has also won the
first prize in T-Robotics Underwater Challenge organized by TSystem
