  • How to choose the right office or desk chair

    When youre employed in a place that consists of a lot of desks and offices you will always be on the move in order to finish your work, however there is downturn to that excess of movement due to the fact that some chairs can consistently harm your spine. So due to that, one should always buy a chair that is ergonomically fit for him and one that fits his back posture in order to avoid back problems.

    What type of chair is ergonomically fit for you

    in this vast and international market, there are many chairs availible that serve and fullfil your ergonomic needs, however it is a known fact that there is no chair that is perfect ergonomically there fore one must endure himself in several tests before purchasing the most ergonomically fulfilling chair. From my point of view, people must buy chairs based on of they are healthy or medically capable of healing or preserving someones back, people should not pick their chairs based on its comfort

    One of the most vital aspects in a chair is the lower back support. due to the inward curve the lumbar spine has, sitting periodically for extended periods of time causes slouching to occur in the posture which often causes strains in the back. The advantage of ergonomic chairs is that it has an adjustable lumbar adjustment which allows the person to adjust based on his needs and medical requirements.

    • Lumbar support. Lower back support in an ergonomic chair is very important. The lumbar spine has an inward curve, and sitting for long periods without support for this curve tends to lead to slouching (which flattens the natural curve) and strains the structures in the lower spine. An ergonomic chair should have a lumbar adjustment (both height and depth) so each user can get the proper fit to support the inward curve of the lower back.

  • Robotic cheetah ‘breaks speed record for legged robots’

    Owners of a new four legged robot have claimed to have broke the world record for the fastest robot in the world, they named their new robot the robotic cheetah. The US Defense Advanced Research Projects Agency said that the mfour legged robot reached a never seen before speed of 29 km per hour, this is considerably fast for a robot, and also the previous record was only about 26 km per hour. The main purpose of the robot project was part of efforts to develop robots designed to more effectively assist war fighters across a greater range of missions. The design of the robots are based of real animal movements, and the movements try to immitate those of fast running animals like cheetahs. The machine is designed to flex and un-flex its back to increase the length of its stride. The four-year project had a aim which was scheduled in February 2011, ultimately aims to produce a robot which can run at fast speeds and that can zigzag and that quickly stop.
    From my point of view such robotic productions may have negative and positive effects. A negative effect in my opinion would be if the robot is used for unpeaceful purposes as a killing machine such as in war, such inventions should focus on serving only in humanitarian cases. Another problem I see with the robot is that in case it is used in war, it might not have the ability to distinguish between civilians and soldiers, so this could drastically increase the number of civilian causalities. However on the other hand there might be a positive aspect to this robot, this is that it could be used for humanitarian issues or for fire brigades and so on. It’s uniqueness from normal animals can cause to have resistance to high heat pressures therefore it could help in such situations. The idea of having such revolutionary innovations enlightens me because it reflects a new era in the world of technology, however I believe that it is vital for it to be used wisely and peacefully.

     

  • Smart car materials

    General Motors displayed newest latest innovation in the field of smart materials for its plans in the 21st century. New technologies such as shape memory alloys and polymers serve as future options for the development of GM in the field of cars. The materials are known to be able to change shape, stiffness or strength when either heat, stress, electric current or a magnetic field is applied and can then return to its former state when the stimulus is removed.

    The discovery of these materials could eventually lead to many possible movable features in cars, and we may even see prototypes as early as 2012. Examples of these advantages would be to include buttons and handles that automatically pop out when required, active surfaces that can move depending on cars speed to ease in the process of implementing effective aerodynamics results, and light-weight actuators and sensors that could replace the heavy motors and hydraulic systems found in today’s cars. The possibility of the creation of cars that can self-heal in the event of damage, or can be designed to change color or appearance at the touch of a button are ones that are revolutionary to the automobile industry. Such a development in the field of cars can undoubtedly revolutionize the human aspect of technology because soon in the future cars can reach abilities never witnessed before, and also such a development will cut down on costs for many people.
