Laser Science and Technology Centre (LASTEC), Delhi, has developed a
Programmable PRF (Pulse Repetition Frequency) Code Laser Target Designator
for performing field checks and carriage trials of laser-guided bombs, projectiles
and missiles. The PRF code programmability in the range 5 to 50 pulses/s with time
interval resolution of 1µs allows field checks on a wide range of Laser seeker units of
varying specifications used in laser guided munitions. The system jointly developed
by EOCM and Optoelectronics Systems and Solid State Laser Divisions of LASTEC has been
completed successfully. The equipment has been field tested with indigenously developed laser
seeker kits as well as laser seeker kits of foreign make.

The viscometer is being used to measure the viscosity of
partially solidified Al-7w/o Si-0.45w/o Mg alloy (A356.0)
under controlled cooling rates within the freezing range.
The information so gathered provides important guidelines
for designing and operating the soon-to-be-established
semi-solid free-form-fabrication facility.
Preliminary experiments were carried out with this
viscometer. Results obtained for A356.0 alloy, cooled at
1 °C/min under a shear rate of 300 S-I, were worked out. It

PATENT GRANTED
Copyrights Obtained
DRDO has been granted patent (Patent No. 218762) titled, An improved Externally-driven Flyback-type dc-to-dc
converter. The patent gives a new design methodology and circuit topology for design of externally-driven flyback-type dc-
to-dc converters. According to Shri AK Maini, Sci G at Laser Science and Technology Centre (LASTEC), Delhi, inventor of
the patent, the new topology is particularly relevant to design of capacitor charging units of flash pumped solid state lasers
used as laser range finders and target designators. The new circuit topology would lead to design of capacitor charging
units with much higher conversion efficiency, and consequently, higher wall plug efficiency for the above mentioned
battlefield laser systems.
Scientific Analysis Group (SAG), Delhi, has received copyrights for two developed software packages named
SAMEEKSHA and HASTAKSHAR under the project PAT CLAN.
SAMEEKSHA: (Copyright No. SW-3714/2007); consists of 32 software meant for extracting features from cipher
text, statistical analysis of word combination and pattern word analysis. Dr Shri Kant, Sci F (Project Leader), Ms
Neelam Verma, Sci F, and Ms Anita Dwivedi, TO B are the contributors.
HASTAKSHAR: (Copyright No. SW-3715/2007); consists of 10 software for selecting prominent features to be
used in various classification models. It also addresses the issue of Curse of Dimensionality in Pattern
Recognition Problems. Dr Shri Kant, Sci F (Project Leader), Ms Neelam Verma, Sci F, Shri Rajesh Asthana, Sci C,
and Ms Anita Dwivedi, TO B are the contributors.
