Concept Realised ( Implemented )

This was my PhD topic. The Goal was to design a broadband
electromagnetic energy harvester that generates energy from
periodic motion such as vibrations.

The technology employs two different physics phenomena together
to achieve maximum power output at different range of frequencies
– (a) the variation of the magnetic field along the direction of
motion of the coil (b) multiple coils introduced in a muti-degree of
freedom structure.

his valuable guidance and Curtin University for providing me
the scholarship to realise this concept.

Conceptual design of a MEMS/NEMS energy harvester that acts as a skin with (a) thermal energy harvesters at the base level where it
contacts the vibration and heat source (human body, engines) and (b) hybrid MDOF vibration energy harvesters that utilize peizo,
electromagnetic and capacitive layers.
I have combines the spatially varying MDOF EMVEH technology (from my PhD) with other energy conversion methods discussed in the
literature to develop this concept.

Invention #3- Mobile Back cover

The concept is to harvest two
forms of wasted energy from the
same setup : 1) when the cell
phone is in the pocket, it is warm
due to body heat and has access
to body vibrations-both of these
energies can be harvested to
charge cell phones.
2)The cell phone vibrates under
the
following
operating
conditions - Vibration mode,
vibrations due to sound from and
to the phone. These are wasted
vibration energies that can be
harvested to charge cell phones.
The other option is to integrate
the MDOF EH layer to battery.

The concept is to have a minimalistic but modular
solution to convert mono-axial energy harvesters to
tri-axial energy harvesters. A similar mechanism can be
used for converting mono-axial motion sensors to
multi-axial sensors.
This concept evolved as I tried to convert my monoaxial multi-degree of freedom energy harvester to triaxial MDOF energy harvester during my PhD. This has
been explained in Chapter 9 of my PhD Thesis .
This is useful for rotating machinery at the axial end of
the rotating shafts where there is possibility of
orthogonal vibrations.
This is cost effective to be used for the future internet
of things based remote condition monitoring of
rotating machinery.

Minimalistic Design for a handy battery
charger.
This battery charger wrist band can fit to
your arm or wrist .
When your mobile or tablet battery drains
off, just plugin the micro USB of this charger
to your mobile using the micro-USB cable
and charge it .
There is a battery slot (optional) wherein you
can insert your own battery and charge it
whenever you want so that you can just
replace the battery in emergency.

CONVERT ANY MINING EQUIPMENT INTO AN
INTELLIGENT ONE BY ADDING MORE EYES TO IT.

Wireless Mine eyes are retrofit self powered proximity sensors are
proximity sensors that are pasted at different locations.
These sensors have an inbuilt battery that is powered through
Micro-USB port. It also has an Piezoelectric energy harvester on
the adhesive side and adheres to the mining equipment surface
when pasted.
These proximity sensors form a self repairing wireless network
communicating with each other and a central station (at driver’s
cockpit)

A Bike Commuting bus that bus parallel to the train network. Often the bikes cannot commute on the freeways (where speed requirement is
greater than 100 kmph).
It is also difficult to have metro trains paths to cover every area. Hence there is a need for bike commuting bus. Here is one intelligent
concept of how a bike commuting bus would look like. This will encourage the people to use bikes. The Senior citizens can have the option
of electric/petrol fitted bikes that can also get into this bus.

An intelligent designed modular replacement panel board that can be used to renovate the existing panel boards in old homes then an there
without the need of dismantling the panel board from the building . The kit is modular to accommodate the different sizes of panel board.

Picture not shown to protect GE’s trade secrets
Developed a stack-up mechanical tolerance analyser software tool to analyse the assembly mechanical tolerances of complex assemblies.
The software was designed using Monte-Carlo simulation to calculate the process capability of the tolerances.

Picture not shown to protect GE’s Intellectual Property
Developed a intelligent panel board (load center) concept for smart grids. This intelligent load center is controlled by a microcontroller
based CPU that can communicate with the mobile devices for monitoring the power.

Continuous Improvement is a requirement in Automotive manufacturing companies. This was the concept of an intranet based idea
tracking system which can be used by the employees to suggest new ideas for improving their existing products and processes.
It starts with employee logging in and suggesting a new idea that can improve existing process or product that goes through various
approval processes. Only the valid ideas are implemented and awarded (if the Company is generous)

Self-retracting Photovoltaic ceiling module that does not affect the aerodynamics of the car. It consists of a Photovoltaic array having
the counter of the car ceiling till the back.
It has an automatic shutter that closes the PV cell when –1.the driver wants it to close,2.when there is rain.
There are two options for PV array to be installed in car:
Type 1: Only on car roof–with rear window
Type 2: On car roof and rear side-without rear window .(rear view should be recognized by rear view camera option)

Suburb Biogas Vending Machine (SBVM) is a
commercialization idea of encouraging use of
residential bio waste.
1.Customer brings the bio waste , dumps it to
the trolley of SBVM.
2. The SBVM then displays the price of the
dumped bio waste.
3.The customer has the option of either
purchase of biogas or earn cash for the biowaste dumped .If the customer wants to
purchase more biogas than what he is
entitled to w.r.t the bio-waste dumped he
swipes the credit card and purchases the
extra gas.
