Hybrid Assistive Limb (HAL-5) 1. Introduction. People often suffer from various disorders related to their physical health‚ which also include disorders of the nervous‚ vascular and integumentary systems‚ muscular and neurologic diseases. Consequently‚ these violations probably affect the musculoskeletal system and complicate the daily lives of these people. However‚ with the daily development of science and technology‚ doctors and inventors are trying to create some kind of device that can make

Regular HEVs most commonly use an internal combustion engine (ICE) in tandem with electric motors to power their propulsion system. Modern mass-produced HEVs prolong the charge on their batteries by capturing kinetic energy via regenerative braking‚ and some HEVs can

HOW ARE REDOX REACTIONS DIFFERENT? Redox is the term used to label reactions in which the acceptance of an electron (reduction) by a material is matched with the donation of an electron (oxidation). A large number of the reactions already mentioned in the Reactions chapter are redox reactions. Synthesis reactions are also redox reactions if there is an exchange of electrons to make an ionic bond. If chlorine gas is added to sodium metal to make sodium chloride‚ the sodium has donated an electron

Furthermore‚ there have been many ways of supplying electricity to the cars including home-rechargeable batteries and hydrogen power. Electric vehicles are a definite possibility for the future because they have the lowest emissions while driving. most people do not know but electric vehicles are out there for people to use. They have not yet replaced the internal-combustion

cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something we are very familiar with: the battery. According to the National Renewable Energy Laboratory‚ or NREL‚ like the battery‚ fuel cells use chemical reactions to generate electricity rather than combustion. Unlike the battery‚ however‚ the "ingredients" for this reaction are not stored within the cell‚ rather they are taken in from outside‚ making their potential so much more efficient
