Keyboard technology

Computer keyboards can be classified by the switch technology that they use. Computer alphanumeric keyboards typically have 80–110 durable switches, one for each key. The choice of switch technology affects key response (the positive feedback that a key has been pressed) and travel (the distance needed to push the key to enter a character reliably). Newer keyboard models use hybrids of various technologies to achieve greater cost savings.

Types

Membrane keyboard

There are two types of membrane-based keyboards, flat-panel membrane keyboards and full-travel membrane keyboards:

Flat-panel membrane keyboards are most often found on appliances like microwave ovens or photocopiers. A common design consists of three layers. The top layer has the labels printed on its front and conductive stripes printed on the back. Under this it has a spacer layer, which holds the front and back layer apart so that they do not normally make electrical contact. The back layer has conductive stripes printed perpendicularly to those of the front layer. When placed together, the stripes form a grid. When the user pushes down at a particular position, their finger pushes the front layer down through the spacer layer to close a circuit at one of the intersections of the grid. This indicates to the computer or keyboard control processor that a particular button has been pressed.

Sabre

Sabre I

The first Sabre was a former knife thrower named Paul Richarde until he was selected by Modred to oppose Black Knight. Paul Richarde was given an armor, an animated gargoyle. and Mordred's Ebony Dagger (the weapon with which Mordred had killed the first Black Knight). He was defeated by Black Knight after his horse Aragorn kicked the dagger from Le Sabre's hand.

Sabre II

The second Sabre is a mutant super villain. His first appearance was in X-Men #106. Young and reckless, Sabre was chosen by Mystique to join her new Brotherhood of Mutants, though never actually participated in any missions. He had the mutant ability of super speed, and took the name of the deceased Super Sabre. It is unknown if he continues to serve Mystique behind the scenes, or if he even retains his powers after Decimation. Hyper-accelerated metabolism augments his natural speed, reflexes, coordination, endurance, and the healing properties of his body.

Switch (house DJ)

David James Andrew Taylor, better known his stage name Switch, is a British DJ, songwriter, sound engineer, and record producer. He is best known for his work with M.I.A.. In the fidget house genre, Switch runs his own music label "Dubsided", as well as the label Counterfeet, established in 2006 with fellow producer Sinden. He has released various singles under his own name, and is also well known for remixing and producing for many major artists. He is a former member of the American electronic dancehall group Major Lazer.

Most notably Switch has worked extensively with fellow British artist M.I.A. co-producing tracks on her albums Arular and Kala. For the latter, he travelled to work with M.I.A. in A. R. Rahman's Panchathan Record Inn and AM Studios and other locations such as Kodambakkam, Chennai and Trinidad and Tobago. He says "When you go somewhere like India, and especially Jamaica, it puts you in a different train of thought, outside of your usual working conditions. They use music as their voice; they use it for politics, for religion. So, I think for people that are struggling, they can use it to vent frustrations, or to celebrate.”
