In pursuit of an invention
But dropping out of the prestigious medical institute meant he needed to prove himself to many people, including his father, who taught psychology at Delhi University. "Now, the burden to prove myself was on me because I had voluntarily taken the decision to quit formal studies," says Pal. For the next three years, he just could not come to terms with the death of his mother and sought solace in the books of Henry James, Samuel Becket and Ernest Hemingway. This made his father worried as he could see Pal falling deep into a hole.
Pal recalls an incident, "One day, the door bell in our house got burnt. My father knew my passion for electronics, so just to divert me, he asked in a challenging manner if I could repair it. I agreed and designed a timer with a new circuit to ensure that it never burns again," says Pal, showing the touch bell which is still working after almost three decades at his house. His father's trick had worked: Pal had rediscovered his calling. In 1984, he landed a contract for designing electronic controls and sound generators for various rides at Appu Ghar, just before its inauguration. He earned about R60,000 for a project lasting 10 days. "It was a lot of money those days. Everyone said I had put my sad past behind and had a great future ahead," says Pal.
That was just the beginning. The project established his reputation as an ace circuit designer and a 'quickie engineer'. Many freelance projects began to come his way. Between 1990 and 2000, he worked as a freelancer for companies such as Maruti, Honda, Duracell and the Nationally Institute for the Visually Handicapped. However, it was his marriage to Ritu Chowdhary, six years junior to her and his father's student, in 2000 that marked a new chapter in his life. "My wife wanted me to be a creative person and not just a circuit designer," says Pal. So, he shifted his focus to research and invention.
In the past few years, he has received as many as nine US patents for his inventions: For the use of induction motor as a sensor, a Personal Mobility Vehicle (PMV), a contact-less non-optical computer mouse suitable for 3D applications, a robotic platform, an electromagnetically controlled valve-less internal combustion engine, a revolutionary electromagnetic gas-operated gun with smooth bore, a BVI-noise reduction technique for helicopters, a linear motor for electromagnetic launch and a very high torque electric motor. Despite all these achievements, Pal is disappointed as he could not peddle his concept for a PMV - a diwheel car with a canopy, which he got patented in 2006, to auto companies. "The PMV can offer a good solution to short distance transportation on congested streets in Delhi. It can also be used as a personal transport to and from Delhi Metro, replacing the cycles at the stations. I wrote to Delhi Metro in this regard but got no response," says Pal...
