May 13th 1958: Velcro® Trademark is registered

George de Mestral, a Swiss mountaineer, tells the story, he was hiking with his dog in 1948 and was frustrated to see all of these burrs covering them both when he returned home. He says he was fascinated by how tough they were to take off and looked at them in a microscope. He saw that they had small hooks that enabled the seed-bearing burr to cling effectively to the small fabric loops on his pants. This was an “aha” moment and he was inspired to design a fastener using the same concept. He called his invention ‘velcro’, combining the French words velour (velvet) and crochet (hook). He predicted: “It will rival the zipper in its ability to fasten.”


The idea was not an immediate success and met with derision by some. He persevered and worked with a weaver from a textile plant in France to develop a nylon type fabric that had the hook and loop fastener concept, patented it in 1955 and trademarked it in 1958. A U.S. patent was filed on May 9, 1958 and awarded on Nov. 21, 1961.


Inspired by the burr, de Mestral created the world's first hook-and-loop fastener. De Mestral originally envisioned VELCRO® Brand hook and loop as a fastener for clothing. Today it is being utilized across a wide range of industries, from healthcare to your garage to the military. While each VELCRO® Brand product is built for a specific task, the principal mechanics remain the same. Just think: the VELCRO® Brand solutions that keep your tablet device mounted to the wall are based on the same principles as the ones that NASA uses to keep their dinner plates from floating in zero gravity space.
The original Velcro® company was formed in 1952 to manufacture this invention and now Velcro® is a multi-million dollar industry.

La mayoría de las personas no son conscientes de que sus automóviles son equipos de alta tecnología, "un computador gigante"; muchos de ellos actualmente cuentan con conectividad inalámbrica, lo que les permite conectarse a redes. Sin embargo, existe el peligro de convertir su automóvil en un teléfono inteligente sobre ruedas, lo que también los convierte en un blanco fácil para los piratas informáticos. Que pasaría si esto sucede?, solo imagine un escenario en que los hackers acceden a los controles básicos de su automóvil, ingresan a su sistema de entretenimiento conectado a Internet y manipulan sus frenos. Los hackers ya han demostrado que este escenario puede pasar; los ingenieros de seguridad Charlie Miller y Chris Valasek demostraron el año pasado cómo podían secuestrar el control de un coche mediante la conexión de las computadoras portátiles en los guarda-fangos.
