      From: treon3verdery@gmail.com              most shoes i have seen in 2020AD were constructed in a way where they could       easily last longer and weigh 29-51 grams less per shoe, that suggests each       shoe has the ability to host 29-51 grams of technology at the same or better       comfort level as 2020        shoes. A laser or Thz emitter, connected to optical fiber at the shoes could       make a stress showing interference pattern on the foot, ankle, and calf       surface (thz sees through socks and pants) possibly extending all the way to       the hips. the computer at        the shoes would either use program logic or a neural network to spot when the       person, from their motion was more than 1% likely to mistorque, twist, or       sprain an ankle or mistorque a joint. Masses at the shoes, or atop the sock       would then rapidly move to        make the computer modelled version of foot and leg motion exist in the       nonspraining, nonmistorqueing range. The suddenly moved 29-51 gram mass at the       shoe/foot area precludes harm. Now with F=MA the shoe mass will be moving very       fast to compensate a        mistorque, one possibility is linear railgun acceleration of mass, powered by       an ultracapacitor, another possibility is changing the contour of the shoe       bottom in less than 1/100-1000th of a second, instantly making say a negative       heel earth shoe(™),        a taller heel, or even a puffed out crescent shape on the shoe base so the       mistorqued foot, ankle, joints, when the shoe does meet the ground meets it       at the most mistorque preventing angle and motion. Polymers that puff, get       squishier or harder with        electricity are published like PMMA and silicone ethanol robot "muscle".       Elderly people and athletes would benefit most from these mistorque preventing       shoes, and possibly mass driver socks. the technology is mostly already       existing, and the shoes could        get electricity wirelessly. These shoe-base customizing shoes with computer       analysis of leg and foot motion could make a custom shoe base to be       preventative of mistorquing in the first place from custom bulges on the shoe       outer base. A layer of chemical        vapor deposition nanothin amorphous fullerene glass which is 1000 times harder       than diamond can be deposited on the outer shoe surfaces              New user interface for tablets and phones: the tablet or phone recognizes       which finger you are using to tap or persist at when using software. Second       finger could mean "act like i'm hovering a mouse on this item" or even give an       equivalent to a mouse        right click with a menu of options that pops up. This gives tablets more       desktop PC like options and abilities. This is great for Microsoft Surface™.       (Right click does a lot in windows). It is possible touchscreens could already       recognize the second        finger from fingertip size and shape of contact alone, or it is possible that       different fingers differ in capacitance.               Better phone and wifi antennas with sectors or stripes. Wikipedia says using       negative refraction index materials as coatings makes antennas an order of       magnitude stronger for the same input energy. And putting a ferrite sheath on       a, perhaps receiving,        antenna makes it 30%-70% more effective, so the really simple technology here       is to alternate negative refraction index metamaterials with actual physical       sectors or stripes of ferrite sheath on the antennas of phones and wifi       utilizing technologies. At        phones this makes it so they radiate an order of magnitude more energy to a       base station from the same amount of battery energy, that allows tremendous       cost savings to phone companies as they can utilize and support base stations       10 times further away,        making for say 10 times less base stations to maintain and build. Similarly       the metamaterial coating on the base station send antennas produces an order       of magnitude greater radiated radio waves, that is then able to reach the       phones that are 10 times        further away. At wifi and wimax similar order of magnitude greater radiated       energy increases then communicate with more (wider radius) IoT (internet of       things) with less routers/base stations. Also its likely obvious but putting       metamaterial negative        refraction index coatings on miniscule IoT antennas gives them an order of       magnitude more radius of communication partners, or the same neighborhood of       communication partners but using just 1/10th the energy to reach them.       Wikipedia says, Through the        application of double negative metamaterials (DNG), the power radiated by       electrically small dipole antennas can be notably increased. This could be       accomplished by surrounding an antenna with a shell of double negative (DNG)       material. When the electric        dipole is embedded in a homogeneous DNG (negative permittivity and negative       medium, the antenna acts inductively rather than capacitively, as it would in       free space without the interaction of the DNG material. In addition, the       dipole-DNG shell        combination increases the real power radiated by more than an order of       magnitude over a free space antenna. A notable decrease in the reactance of       the dipole antenna corresponds to the increase in radiated power."              Negative refractive index and metamaterial lenses could be a soft humaniform,       or fingernails at humaniform way of doing photon or other microscopy at sizes       much smaller than a wavelength of visible light. If a social companion robot       or other robot was        scanning a human for wellness it could ask for a saliva sample, or a used       toothbrush, then apply the saliva sample to its fingernail for likely better       than 2018 20 nm or less resolution microscopy, smaller than many bacteria              Negative refractive index metamaterial Microwave ovens that use 1/4 to 1/10       the energy to warm things are likely possible.              Possible way to get an order of magnitude more force out of diamagnetism or       other magnetism: 1) surround the magnet or the diamagnetic bismuth with a       negative refraction index material, the idea is that the DNG (negative       permeability, negative        permittivity) material adjusts the "coupling" or transparency to electrons to       make them less aloof, the nonaloof electrons then reshape the magnetic field       they make/are surrounded with, that other things like a bismuth chunk or wires       at a moving winding (       generator rotor, motors) respond to, then respond in new ways with greater       alacrity.                     [continued in next message]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
