8. Aerospace Test Equipments
Test equipments were designed and prototyped for testing of Ice detector and Interphone Handsets on Aircrafts.
7. OSVR positional tracking bracelet prototype
A bracelet was designed and prototyped for precise tracking of hands and forearm for virtual reality applications. IR sensors on the bracelet along with a dedicated IR camera was used.
6. Intelligent TLEDs with dynamic Daylight Harvesting
This work improved the performance of the existing Philips Lux-Sense product. The task involved reformulating the simplified system level model by taking practical non-idealities into account. The right sensor had to be chosen and appropriate signal conditioning circuits were designed and tested to meet the specifications. Atmega644PV was used to implement the system level model and the proposed algorithms. Matlab GUI was finally developed for real-time system analysis and debugging after integration.
5. ARINC 429 Holt Transmitter (Basic)
Upon the foreseen obsolescence of the HOLT series for the ARINC 429 protocol implementation, functional realization of the transmitter was realized at a basic level.
4. Characterization of Piezo sensors & design of Zero power motion activated switch
This work proposed methods for further miniaturizing the Philips Lifeline fall detection product. Also implemented novel methods to save power with a new energy efficient triggering mechanism and thus reduce the size of the battery. A prototype PCB was realized to prove the proposed concepts and for mechanical (vibrational) characterization of piezo sensors.
3. Activity Recognition with Multiple Ultrasound Sensors
The goal of this project is to recognize activities in an office environment and adjust the lighting conditions accordingly. We use ultrasonic sensors to recognize the different activities at the desk and the data is processed simultaneously to make adjustments to the lighting. With proper classification methods, we connect the data readings from the sensors to predetermined activities and with this information, we can adjust the lighting.
Activity Recognition with Multiple Ultrasound Sensors.pdf2. S3BOT
The mining industry, chemical factories, space industry, accidental gas leakages in any scenario are some of the many places we have tried to address. The major impediment when dealing with such situation is that it requires a trained person to actually put himself in danger to confront these situations. This project titled “S3BOT” resolves the above problems, with the ability to remotely control the R.O.V that transmits data wirelessly to the user thus putting him out of harm. The robot is able to imitate an electronic watchman localizing leaks and detecting a source of contamination.
The R.O.V has a sensor that is mounted on it and an onboard video/audio transmitter to help with the navigation of the R.O.V. The data from the sensor is transmitted wirelessly, via Radio Frequency (R.F). The base station receives this data, which is then interpreted and displayed suitably. Multiple sensors can be used and the vehicles can be networked. Spontaneous reactions can be performed like raising an alarm. The scope for the future development of this prototype is large.
1. PROTUNIK
PROTUNIK (Unique Protection) is an integrated, cost-effective, efficient system to solve the following:
- Aid in negotiating turns (L,T,X types) by giving a warning to the driver.
- Automatic decrease in light intensity as the automobile approaches another vehicle on the opposite side during the night.
-Uses Ultrasound transducers for distance/obstacle estimation
