Renewable energy sources include the sun, wind, water, geothermal energy and biomass.These renewable sources are all natural occurring elements. If these sources are utilized properly we can able to produce energy in large scale without disturbing earth’s nature and not making pollution.
Solar based Refrigerator This fridge will be suitable for cooling purposes meant for small objects and will have a relatively small chilling time as compared to the normal refrigeration systems.
A major goal of the PV industry is to develop high-efficiency, low-cost solar cells and devices. Recently, several approaches have been proposed for approaching the thermodynamic limit of solar energy conversion.
Energy storage is the capture of energy produced at one time for use at a later time. A device that stores energy is sometimes called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic.
Haptic technology refers to technology that interfaces the user with a virtual environment via the sense of touch by applying forces, vibrations, and/or motions to the user.
Child rescue This robot is capable of moving inside the bore well, according to the human comment by PC and also pick and place based on the arm design. It is a low cost human controlled robot used to monitor and gives an insight view of rescuing the child safely.
A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, Relays are used where it is necessary to control a circuit by a low-power signal or where several circuits must be controlled by one signal.
Design of Traffic Signal The advantages of traffic signal includes an orderly movement of traffic, an increased capacity of the intersection and requires only simple geometric design.
Materials that can change one or more of its properties in response to an external stimulus are called smart materials. the shape of the material will change in response to different temperature or application of electrical charge or presence of MF
Polyfuses is a new standard for circuit protection .It is re-settable by itself. Many manufactures also call it as Polyswitch or Multifuse. Polyfuses are not fuses but Polymeric Positive temperature Coefficient Thermistors (PPTC)
Shape memory alloys (SMA's) are metals, which exhibit two very unique properties, pseudo-elasticity(An almost rubber-like flexibility demonstrated by shape memory alloys), and the shape memory effect (deformed and then returned to their original shape)
VSC Application for HVDC systems of high power rating (up to 200MW) which are currently in discussion for several projects. The underlying technology of VSC based HVDC systems, its Characteristics and the working principle are also presented.
A paper battery is a flexible, ultra- thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose based paper.
Infrared Thermography is nothing but the temperature profiling of a surface or point. As the name suggests, infrared thermography is based on Infrared(IR) technique. surface temperature can be detected and quantified by the help of IR scanning system.
voltage stability in power systems at which voltage stability in transmission lines and system buses are carefully analysed based on their V-Q and V-P relationships. Four indices are proposed; two for voltage stability analysis at system
One solution is to remove the driver from the control loop by fully automating vehicle driving functions.which include WLAN for connectivity, GPS navigation systems for navigation, Radar scanning to avoid collisions. eliminating human interference
CT scanning uses special x-ray equipment to obtain image data from different angles around a body and then shows a cross section of body tissues and organs. i.e., it can show several types of tissue-lung,bone,soft tissue and blood vessel with clarity.
Blood Collection Monitor is an advanced device which is aimed to collect the blood prior to collection with use of latest technology in place of earlier, insufficient, conventional methods i.e. without accurate weight by using random movement.
Distribution system is that part of the electric power system which connects the high voltage transmission network to the low voltage consumer service point.
The hybrid-cascaded multilevel converter proposed in this paper can actualize the charging and discharging of the battery cells while the terminal voltage or SOC balance control can be realized at the same time.
