Modulation Aided Recording on Magnetic Tape to store More Information on Single Tape


More than one modulated signal are recorded on a magnetic tape. The recorded signal when reproduced is fed to a adjustable tuning circuit where specific frequency is selected for demodulation and amplification. User to change frequency instead of changing the tape (cassette). (Similar to changing frequency on a radio receiver device).

   Dual Mode Amplitude Modulation to Transmit Double information Over AM Carrier Wave


Transmission of two signals on one amplitude modulated carrier wave. Dual mode amplitude modulation modulates different signals on positive and negative amplitudes of the carrier wave. The invention utilizes the fact that an Amplitude modulated signal, when de-modulated, uses a diode circuit to remove one side of the amplitude. This method utilizes redundant part of signal to transmit more information or data.

   Screw less Contact Terminal for Easy and Fast Assembly 

Screwless contact terminal thumbnail

Spring connector to allow "Press, Insert, Release" method to fix electrical connections to electrical accessories and enable faster and easier assembly of circuits and boards. The connectors do not require screws to fix connection. Though these are not new connectors and are in use for low voltage circuits, these are not currently used in household and industrial electrical accessories.

   Multiple Laser Optical Transceiver to Transmit 2 byte per Clock through Optical Fibre

Transmit 2 bytes per clock pulse through an optical fibre. Multiple lasers with variable intensities and wavelengths create combinations and each combination represents multiple bits of data. A combination of 4 lasers each with 16 intensity levels could transmit 2 byte per clock pulse.  Thus increasing the speed of data transmission.

   Direct Energy Conversion from Hydrocarbon Fuel


A device to convert of chemical energy to electrical energy in hydrocarbon by using electromagnetic waves (laser). The laser provides a catalytic quanta of energy required to remove an electron from H atom (Ionization energy). Energy extracted in electrical form is more efficient for use and can be stored for future use.
