Relevant Background: "Cork is an impermeable buoyant material, the phellem layer of bark tissue that is harvested for commercial use primarily from Quercus suber (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance. Because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is wine stoppers. The montado landscape of Portugal produces approximately half of cork harvested annually worldwide..Cork's elasticity combined with its near-impermeability makes it suitable as a material for bottle stoppers,..Cork has an almost zero Poisson's ratio, which means the radius of a cork does not change significantly when squeezed or pulled...Cork is an excellent gasket material. Some carburetor float bowl gaskets are made of cork, for example..Cork is also an essential element in the production of badminton shuttlecocks...Cork's bubble-form structure and natural fire retardant make it suitable for acoustic and thermal insulation in house walls, floors, ceilings and facades. The by-product of more lucrative stopper production, corkboard is gaining popularity as a non-allergenic, easy-to-handle and safe alternative to petrochemical-based insulation products...Sheets of cork, also often the by-product of stopper production, are used to make bulletin boards as well as floor and wall tiles...Cork's low density makes it a suitable material for fishing floats and buoys, as well as handles for fishing rods (as an alternative to neoprene)...Granules of cork can also be mixed into concrete. The composites made by mixing cork granules and cement have lower thermal conductivity, lower density and good energy absorption. Some of the property ranges of the composites are density (400–1500 kg/m³), compressive strength (1–26 MPa) and flexural strength (0.5–4.0 MPa)..

  • In musical instruments, particularly woodwind instruments, where it is used to fasten together segments of the instrument, making the seams airtight. Low quality conducting baton handles are also often made out of cork.
  • In shoes, especially those using welt construction to improve climate control and comfort.
  • Because it is impermeable and moisture-resistant, cork is often used as an alternative to leather in handbags, wallets and other fashion items.
  • To make bricks for the outer walls of houses, as in Portugal's pavilion at Expo 2000.
  • As the core of both baseballs and cricket balls. A corked bat is made by replacing the interior of a baseball bat with cork – a practice known as "corking". It was historically a method of cheating at baseball; the efficacy of the practice is now discredited.
  • in various forms, in spacecraft heat shields[25] and fairings.
  • In the paper pick-up mechanisms in inkjet and laser printers.
  • To make later-model pith helmets.[26]
  • Hung from hats to keep insects away. (See cork hat)
  • As a core material in sandwich composite construction.
  • As the friction lining material of an automatic transmission clutch, as designed in certain mopeds.
  • Alternative of wood or aluminium in automotive interiors.[27]
  • Cork slabs are sometimes used by orchid growers as a natural mounting material.
  • Cork paddles are used by glass blowers to manipulate and shape hot molten glass.
  • Many racing bicycles have their handlebars wrapped in cork-based tape manufactured in a variety of colors.
  • To make architectural models.
  • As a sustainable alternative to traditional substrates in fragrant sachets [2] by Castelbel, a Portuguese brand of luxury home fragrances and bath & body care products." ("Cork", https://en.wikipedia.org/wiki/Cork_(material))

*** Relevant Background :  " An  automatic door , also known as an  auto door , is a  door  that opens automatically, without the need for human intervention or usually upon sensing the approach of a person. A person can be detected by microwave pulses,  infrared sensors  , or pressure-sensing pads...  " ( Automatic door - Wikipedia ) ***  Relevant Material :  " THEY HIT PEOPLE MORE OFTEN THAN YOU THINK AND CAN CAUSE SERIOUS PERSONAL INJURY Most of us walk through automatic doors on a regular basis. Most retail stores have some form of automatic doors, whether they are sliding doors, revolving doors, swinging doors, or folding doors. Most people who pass through automatic doors don't think about the fact that they can be struck by the door or trapped between the door and door frame.
