POWERED EXOSKELETONS

Powered exoskeletons are wearable mobile machines powered by a system of electric motors, pneumatics, levers, hydraulics, sensors or a combination of technologies that allow for limb movement with increased strength and endurance. This technology is developing very fast and is already in use in many fields. People with movements related disability will be able to move very easily. Precision will be increased in surgeries. Developing a full body suit that meets the needs of soldiers has been proven challenging, but new and advanced designs with improved technologies and software will definitely benefit the military, police, fire-fighters later on. Modern Industries directly use these kinds of machines for efficient business. Though it makes you stronger, run faster, jump higher, still one of the biggest challenges engineers face is power supply if they are to be worn in the field. They risk explosion, might require frequent charging. Yet hydrogen cells have been used in some prototypes. Other challenges are that they should not be heavy, joint flexibility should mimic human movement flawlessly, the algorithms controlling power and modulation should be highly efficient, adaptation to user size variations. This technology is not user-friendly yet but lots of private companies and governments as well have started to invest more for research purposes. Powered exoskeletons date back to 1890 which used energy stored in compressed gas bags to assist movements made by Nicholas Yagin. In 1917 Leslie C. Kelley developed pedometer which operated on steam power with artificial ligaments acting in parallel to the wearer’s movement. Lastly, this technology will definitely help make this planet a better place to live.

NEUROIMAGING IN IDENTIFYING DISORDERS

NEUROIMAGING IN IDENTIFYING DISORDERS Neuroimaging deals with the in vivo applications of various techniques to illustrate and study the structural & functional characteristics of the nervous system. Neuroimaging can be classified into two categories: • Structural neuroimaging, which involves the imaging of the structure of the nervous system and the diagnosis of intracranial injuries and tumours. • Functional imaging, which involves the study and diagnosis of metabolic diseases and cognitive research. The most widely used techniques involved in the process of neuroimaging are: 1. Computed Tomography (CT) or Computed Axial Tomography (CAT), in which X-ray images of the brain from various directions are taken and presented as cross-sections of the brain. 2. Magnetic Resonance Imaging (MRI), which uses magnetic fields and radio waves to obtain high-resolution 2D or 3D images of the brain. 3. Positron Emission Tomography (PET), which measures emissions from radioac...

EMOTION SENSING TECHNOLOGY

Emotion is a mental state associated with the nervous system brought on by chemical changes variously associated with thoughts, feelings, behavioural responses, and a degree of pleasure or displeasure. Reading and understanding emotions can lead to wide-ranging opportunities. Emotion sensing technologies are being widely used in many applications to effectively understand the users' mood and use that information to do something productive. EMOTION SENSING TECHNOLOGIES can be used in various fields such as personal robots, driverless cars, educational software, consumer electronic devices, video games etc and is on the verge of becoming the next big thing. THE TECHNOLOGY INVOLVED: SKIN CONDUCTANCE SENSORS: Skin conductance (SC) is an index of sympathetic nervous system (SNS) activation and emotional arousal. To measure skin conductance, a small electrical potential is applied between two electrodes strapped or taped to the palmer side of the hand, and the amount of ...

BLACK HOLE & SPACE-TIME RELATION

BLACK HOLE & SPACE-TIME RELATION                                 W e are all pretty familiar with the term  'Black   Hole' . Well, what does it really mean? Firstly, the 'Black Hole' is not black at all. It is a kind of void from which light cannot escape. According to the general theory of relativity, proposed by Sir Albert Einstein, the black hole is that region of space and time, where the gravitational attraction is so strong that nothing can escape from or through it. A huge, enormous amount of mass is concentrated over a very small volume. And, consequently, the density of the black hole becomes incredibly strong. ⮚       Formation of the 'Black Hole':  Well, so far as the creation of the black hole is concerned, it is speculated that if the centre of an enormously distributed star collapsed and, as a result, the 'SUPERNOVA EXPLOSION' occurred. The...
