is a 16bit stack
based microcontroller designed to be
a radiation-hardened to suit Space applications where
very high speed control tasks are to be performed.
The Emulator for this
processor which was not available has been designed
Presently this emulator is
used by several divisions of ISRO
all over India. Some of the features of this emulator are as
step execution with status reporting on all registers
on various conditions like :Instruction fetch at an
address ,I/O activity,
Read,Memory Write, Interrupt
and also asynchronous Break
of Time elapsed while executing a routine in number of
memory of 64K
memory of 64K cycles.

is an LCD based Data Acquisition system for real time
scanning of critical vehicle parameters for the purpose of
data logging , audio visual warning and to assist vehicle
maintenance scheduling. The system accepts On/Off and analog
signals from electromechanical switches and sensors fitted
on the equipment subsystems. It will log real time data to
provide enhanced diagnostic message. The logged data can be
retrieved later to study equipment history failure analysis.
four keys provided on the front panel are used to operate
certain basic functions like display equipment parameter,
set limits , modify calibration table etc., A 320 x 240
pixels LCD on the front panel displays the warning
symbols of the parameter, operating hour of the
vehicle , vehicle speed in digital format and warning
machines are used for various processes in the manufacturing
activities. During the activity in a day, the machine is
down for many reasons. MDTR is an intelligent addressable
device which can be fitted with each machine to record the
reason and the duration for which the machine is down. When
any of the machine is switched off, the attached device will
not allow the machine to be switched on unless operator
enters the proper Reason
Code through keys provided on front panel of that device
status of the machine when it is queried by the master
device (PC). The master
will be communicating with several such slave devices
on TDM basis and the total down time for
each reason is calculated and maintained in database
on daily basis which can be used for the analysis.
With the increase
in customer expectations and requirements it has become
essential to provide more information to the lift passengers
either to make their travel easier or for the service
provided to make use of the precious time of the passengers
in promoting a company , product or service.
There are two
units in this System.
Information Interface (LII) –collects digital data
corresponding to the car position, movement and other
informations like overload, lift under maintenance etc.,
from the machine controller and sends it to the Display
Module Interface (DMI) along with the time and date.
Module Interface. (DMI) – consists of 320 x 240 pixels
LCD on which the floor number, Time, Date, room
temperature and other messages like overload, lift under
maintenance etc., along
symbols will be displayed. DMI will be placed in each
landing and inside the lift.
It is a 20
character by four row Dot Matrix display with the character
height of 2”. The messages can be scrolled horizontally /
vertically . Maximum
of 64 characters can be fit in each row for horizontal
scrolling and maximum of 20 rows (20characters in each row)
can be scrolled vertically. The characters can be selected
to give different attributes like flashing a character,
reversing the image, underline etc.,
System has an RS232C port to interact with a PC. A VB front
end software is designed to download the messages to be
displayed .The downloaded messages and attributes
can be stored in the internal memory so that it can
be disconnected from the PC and made portable. The VB front
end also provides for the user definable character fonts.
process plant where heaters are deployed to control and
maintain temperature at specified limits will have problems
of rejections due to failure of heaters since the
temperature variations will be noticed only after some time
depending on the process inertia. Hence, it is desirable to
sense the failure of heating element itself that will help
cutting down process rejections.
Annunciator is a system that is used to monitor the heaters
and raise an alarm if any heater fails. The System is
designed around a microcontroller, which can be used in a
process plant where a large number of heaters are used.
Alternately this can be used in any industry where motors,
IR bulbs are to be monitored.
instrument basically comprises of two parts. The first unit
is the fault sensor which senses the performance of the
heater and the second is the fault annunciator to give audio
