The necessary use of one’s hands during extravehicular activity makes the spacesuit’s gloves a critical component. Over the years, the United States of America’s astronauts have seen many variations of their gloves (Jordan 9). One of the first glove iterations was for the Mercury program (Figure 2) and resembled a sophisticated rubber glove from 1959 to 1963. Simple in style, they were made out of a ribbed material for ease of grasping controls and had small lights on the first finger of each glove to allow the astronauts to better see the control panel (Southern 1). The Gemini gloves (Figure 2), used from 1962 to 1966, further improved on the design used during Mercury missions featuring laced-up restraints, in addition to the later addition of adjustable straps and a palm restraint bar to increase comfort (NASA). The gloves for Mercury and Gemini programs overall had less requirements and lower complexity than future gloves as they would not be needed for extravehicular activity (Southern 1). The dawn of the Apollo program sparked a new type of spacesuit gloves, as, in contrast to the ones used mainly inside the spacecraft, the new gloves would have to withstand use during extravehicular activities including the trip to the moon in 1969. The new set of gloves, known as the Extra-Vehicular gloves (Figure 2), was more bulky and included the feature that each glove was molded from molds of the astronauts’ hands. Two of the main foci during the design process were protection and usability. Chromel-R (Figure 1), an expensive, woven-steel fabric, was used to increase the gloves’ protection from abrasion. The fabrication of the fingertips was from silicone, allowing astronauts some fingertip sensations for better control and usabilit... ... middle of paper ... ...2000. HowStuffWorks.com. 1 May 2014.

Over 84 years ago New York was the city of swing. In a realm where culture clashed with politics, race with class and gender with society most teenagers spent an ample amount of their spare time dancing to the music of Cab Calloway, Benny Goodman, Duke Ellington and the likes of others. With the music, blasting in their ears and sweat dripping of their skin the youth was engulfed in a period that would come to stand as a turning point for African-Americans. Despite the rage of the music, there is no question that appearances and the right attire also played a prominent role in the culture of that time. In a society wherein which, Blacks were discriminated and stereotyped against their clothing distinguished and set them apart. The Zoot-Suit, one of the significant symbols of fashion during the era of Swing music was more than embellished get-up. It was a statement, a rebellion, a cultural identification even, but mainly it was a reminder of the social order of society that failed to express and identify certain races1. Although many have argued that racial tensions leading up to the riots emerged from the attitudes of the various races, I stand that fashion choices chosen by the youth of that period played a substantial role in the insurgence. This paper explores the history of the suit, its social and political contexts, its connection to music as well as the implications of fashion choices during the 1930’s and 1940’s.
Finally, the third change involves the utility uniform itself, also known as “cammies”, giving it a complete makeover. The current cammie design for all branches of the Armed Forces is over twenty years old. The textile industry has made many advances in the production of clothing providing more comfort and durability. Revolutionary advances within the clothing industry, Velcro and zippers, are being tested on the new cammie uniform.
In addition, future innovations and designs are on the way to further reduce head impact res...

the plastic football helmet was invented. It was really the same as the leather helmet but
I also wear a high-vis vest on site to make myself more noticeable to anyone working nearby. I also wear protective gloves, as I am cutting tiles the edges can be quite sharp and could cut my hands/fingers so in this case I use gloves to prevent this from happening. I wear steel toe cap boots which are the right size and comfortable to prevent hurting my feet/toes. As a tiler carrying heavy boxes of tiles around to different locations there is a chance I could drop them and without steel toe cap boots on they can possibly break your toes or in other cases your foot. I wear a hard hat adjusted to the right size, which is perfect for the job and not worn out to prevent hurting my head from falling from above.
Preview: First we’ll talk a little about the origin of the true sport and how it came to be, second, we will break down the many stages of evolutions of the glove and third i’ll explain my personal experience to the sport.

If any suits are needed. In a report, suits are worn for protection but are not flexible enough to wear. Movements in the suits are long and slow. In the suits, bending down or crouching in the suits is said to be almost impossible (Byrd 5). This, makes it hard for them to work and even harder to analyze a crime scene.

Astronauts have changed of the years, so have the equipment, technology, and teams. Over years most things improve, this is no exception when it comes to space travel. This doesn’t mean that things don’t get left behind. Things that were considered the best back then,might even become obsolete, but other become legends. In this article you will find information about Neil Armstrong, the Apollo 11, and the technology they used to send the first man on the moon.
Human skin begins to freeze and develop frostbite at 15 degrees Fahrenheit. In many places all over the United States, having a winter with temperatures this low is more than normal. In fact, it is expected. Wearing multiple layers to protect skin is crucial, and that includes on hands as well. Normal touchscreen displays like phones and tablets require skin contact or warmth to use a phone. Tech-friendly gloves have been created but are not always stylish, and consumers should not feel required to purchase an external piece of equipment that is compatible with their phone to keep their hands warm. Normal gloves should be able to be worn in frigid temperatures but also allow for the use of these devices.
When people are swimming, apart from the swimming technique of individual, there is another important factor affecting the speed, which is the drag of body. Therefore, the properties of the high technology swimwear are also designed based on how to reduce the drag.
• Washing hands after touching blood, body fluids, or other contaminated items, even when gloves are worn.
This article is about how technology help astronauts land on the moon. It talks about the communications, protective coatings, computer systems, cameras, breathing devices, and fabric structures that made man’s step on the moon possible. This article work with my topic because it explains how the landing on the moon led to the development of many technological advances and products.
