Toyota RAV4 Key Protector

Posted by Matilda Sanchez on September 14, 2020 at 8:25 AM Comments comments ()

Entre los tipos de llaves de auto están las llaves mecánicas, que son las de metal completas las cuales no tienen ningún tipo de tecnología electrónica. Luego vinieron las VATs, muy usadas por vehículos americanos tipo Chevrolet durante los años 90. Mi primer Cadillac tenia este tipo de llave en el cuello de la llave tiene un selenoide que transmite a la anilla de la ignición un código de seguridad para liberar la ignición. Los transponder llegaron al final de los 95 para quedarse. Las llaves integradas que contienen un transponder y un control remoto comenzaron cerca de los 2005. La tecnología de proximidad comenzó aproximadamente en el 2005. Todas las llaves electrónicas tienen algo en común, el manejo cuidadoso y el mantenimiento.

Para poder transferir efectivamente la radio frecuencia la capa exterior del cuerpo de la llave es de plástico. Estas llaves necesitan protección de los impactos que ocurren durante la vida cotidiana, sin mencionar el que se caigan, se mojen o se exponga a temperaturas altas si se dejan expuestas al sol por ejemplo.

Entre los diseños están las llaves plegable o “ sword Blade o Flip key” como les denominan en ingles. El diseño plegable es el más difícil de proteger, debido a su construcción. Este protector lo puede comprar en Amazon, es perfecto y muy práctico para la toyota  RAV4. Es hecho de fibra de carbono. Maneja que se despliegue la parte de metal de la llave sin que se suelte el protector.

10 Things You Didn't Know About UL's Safe Testing

10 Things You Didn't Know About UL's Safe Testing

 

The best safecrackers in the business never steal a penny. They work for UL.

 

UL has been testing and certifying safes for more than 80 years. The first safe tested for burglary resistance was in 1923 and the first bank vault in 1925.

 

Chisels, wenches, screwdrivers, power saws, cutting torches, crowbars, abrasive cutting wheels, jackhammers, even specified amounts of nitroglycerin are just a few of the "tools" UL technicians use during a safe attack. The idea is to test safes to worst-case scenarios. They use tools that could be found at any construction site or hardware store. They also analyze blueprints as if the burglar might have blueprints of the design and attack its weakest points to evaluate the safe for certification.

 

UL's safe attack tests are conducted by a two-person crew. The object is to create an opening large enough to withdraw "valuables" (anywhere from 2- to 6-square-inches on a safe and up to 96-square-inches on a vault), activate the locking mechanism so the door opens or to cut as many bolts from the door as necessary to pry it open before the time specified in the rating requirement expires.

 

Safes are rated for their resistance to attack against specific tools for a set period of time. There are a dozen different ratings, everything from ATM machines, to gun safes to bank vaults. For example, a safe that bears a Class TRTL-15X6 rating, which might be found in a jewelry store, should resist a hand tool and torch attack for a minimum of 15 minutes. A TRTL-30X6-rated safe, which would protect important documents or store money, should withstand an attack for 30 minutes. The ultimate safe rating-a TXTL60-should withstand an hour's worth of attack that includes the use of 8 ounces of nitroglycerin.

 

Because of the size and weight of certain safes and vault doors, it is not always practical to have the product shipped to UL's laboratory locations. UL's burglary protection staff has traveled to destinations such as Japan, France, Israel, England, Finland, Taiwan and India.

 

In addition to burglary protection ratings, UL also rates safes for their fire resistance protection. Class 350 safes protect paper documents, Class 150 safes protect magnetic tape and photographic film, while Class 125 safes protect floppy disks. In addition to the Class Rating, safes obtain an hourly rating for fire resistance-anywhere from 30 minutes to four hours.

 

Another cool test UL runs on safes is an impact test. This test simulates a safe falling though multiple stories of a building-resulting from a fire that has weakened the structure. After the safe is heated to 2,000 degrees Fahrenheit in a furnace, it's raised three stories and dropped onto a pile of bricks. In order to meet the requirement, the safe can't pop open. Temperatures inside can't rise to above 300 degrees Fahrenheit and sample papers left inside have to be readable.

 

The specialized suits you sometimes find technicians wearing are not just for show. Their entire ensemble, including protective coat, helmet and gloves, protects the crew against the adverse effects of sparking. After all, safety can't be taken for granted, even within the walls of UL.

 

Safes are just one of the 19,000 product categories that UL tests and certifies. While UL's burglary protection team cracks combinations, shatters glass and fires .44-caliber bullets at body armor, other UL engineers and technicians keep busy testing everything from TVs, coffee makers and holiday light strings to fire extinguishers, medical CAT scan equipment and building materials.
