AME049  |  Self-pumping magnetic cooling

The technology described herein is related to a device for simultaneous self-pumping and magnetic cooling. These devices can regulate on the principle of change in magnetization of ferrofluid with temperature.  The cooling device's performance is strongly depends on the heat load, magnetic particle content, magnetic field, shape of the device. Lowering temperature by 28 °C was achieved by the application of 0.3 T magnetic field. The designed system is self-regulating device as increase in heat load will cause an increase in driving force for the flud motion which eventually enhance heat transfer from the heat source to the heat sink.

SDE018  |  Electromagnetic Vibratory Energy Harvesting Technology

With the increasing attention to the Internet of Things (IoT), there is an increasing demand for energy harvesting technologies for supplying power to sensor nodes.  This technology allows for the generation of electricity at a high energy density of more than 3mW, which is by far greater than conventional methods, such as piezoelectric method or electrostatic method.  According to this technology, thick-film magnets are used for generating electricity.  A cantilever structure is employed for generating electricity by electromagnetic induction using inertial force vibration.  This device shows a large amplitude in resonance with the frequency of the vibration source.

SDE037  |  Power Sensing Method for Energy Harvesting and Low Power Electronics

Conventional power sensors or analogue to digital converters (ADCs) work under the assumption of a constant and stable power supply. This assumption is not applicable to energy harvesting systems because power supply drops while the system power dissipates, and rises when new energy is harvested. Hence, what is needed is an ADC that functions correctly in the absence of a stable power supply. The technology provider has developed a solution using a tiny proportion of the charge being sampled to power the ADC. This technology provides run-time power sensing that functions correctly in the absence of a stable power supply.

SDE066  |  Automated Electrical Protection System

Power continuity is important since appliances require a continuous electrical supply. Fault occurring due to a short circuit in the ground or overloading in the system will trip the Earth Leakage Circuit Breaker (ELCB) to disrupt supplies of connecting appliances. It is imperative that fault location detection be in-place to ensure power continuity and reliability, in which the fault may be isolated from the system. This invention is the first automated system to offer this protection in the market.

USS016  |  Ultimate Regenerative Cooling System Requiring No Power Supply

Conventional cooling systems, such as air cooling system using fans or water cooling system using pumps, require external power supplies.  In addition, such movable members as fans or pumps require maintenance.  In order to solve these problems, the present technology offers a cooling system using a regenerative pump which operates with the magnetic body force of thermos-sensitive magnetic fluid for cooling waste heat.
