Crossbar (computer Hardware Manufacturer)
Crossbar is a company based in Santa Clara, California. Crossbar develops a class of non-volatile resistive random-access memory (RRAM) technology. The company in 2013 announced its goal was a terabyte of storage on a single integrated circuit, compatible with standard CMOS semiconductor manufacturing processes. History Crossbar was founded in 2010, by George Minassian, Hagop Nazarian, and Wei Lu. As part of the University of Michigan Tech Transfer program, in 2010, Crossbar licensed resistive RAM (RRAM) patents from the University of Michigan. Crossbar filed patents relating to the development, commercialization and manufacturing of RRAM technology. In August 2013, Crossbar emerged from stealth mode and announced the development of a memory array at a commercial semiconductor device fabrication facility. It was said to deliver faster write performance; lower power consumption and more endurance at half the Die (integrated circuit), die size, compared to NAND flash memory. Si ...

Crossbar Switch
In electronics and telecommunications, a crossbar switch (cross-point switch, matrix switch) is a collection of switches arranged in a matrix configuration. A crossbar switch has multiple input and output lines that form a crossed pattern of interconnecting lines between which a connection may be established by closing a switch located at each intersection, the elements of the matrix. Originally, a crossbar switch consisted literally of crossing metal bars that provided the input and output paths. Later implementations achieved the same switching topology in solid-state electronics. The crossbar switch is one of the principal telephone exchange architectures, together with a rotary switch, memory switch, and a crossover switch. General properties A crossbar switch is an assembly of individual switches between a set of inputs and a set of outputs. The switches are arranged in a matrix. If the crossbar switch has M inputs and N outputs, then a crossbar has a matrix with ''M'' × ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latch (hardware)
A latch or catch (called sneck in Northern England and Scotland) is a type of mechanical fastener that joins two (or more) objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a ''keeper'' or ''strike''. A latch is not the same as the locking mechanism of a door or window, although often they are found together in the same product. Latches range in complexity from flexible one-piece flat springs of metal or plastic, such as are used to keep blow molded plastic power tool cases closed, to multi-point cammed latches used to keep large doors closed. Common types Deadbolt latch A single-throw bolt. The bolt can be engaged in its strike plate only after the door is closed. The locking mechanism typically prevents the bolt from being retracted by force. Spring latches * Latch bolt An extrem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Top Tube
A bicycle frame is the main component of a bicycle, onto which bicycle wheel, wheels and list of bicycle parts, other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the ''diamond frame''. Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and Bicycle fork, fork of a bicycle and sometimes includes the Headset (bicycle part), headset and seat post. Frame builders will often produce the frame and fork together as a paired set. Variations Besides the ubiquitous diamond frame, many different frame types have been developed for the bicycle, several of which are still in common use today. Diamond In the diamond frame, the main "triangle" is not actually a triangle because it consists of four tubes: the head tube, top tube, down tube ...

Goal (sport)
In sport, a goal may refer to either an instance of scoring, or to the physical structure or area where an attacking team must send the ball or puck in order to score points. The structure of a goal varies from sport to sport, and one is placed at or near each end of the playing field for each team to defend. For many sports, each goal structure usually consists of two vertical posts, called ''goal posts'', supporting a horizontal ''crossbar''. A ''goal line'' marked on the playing surface between the goal posts demarcates the goal area. Thus, the objective is to send the ball or puck between the goal posts, under or over the crossbar (depending on the sport), and across the goal line. Other sports may have other types of structures or areas where the ball or puck must pass through, such as the basketball hoop. Sports which feature goal scoring are also commonly known as invasion games. In several sports, sending the ball or puck into the opponent's goal structure or area is ...

Electricity Pylon
A transmission tower, also known as an electricity pylon or simply a pylon in British English and as a hydro tower in Canadian English, is a tall structure, usually a steel lattice tower, used to support an overhead power line. In electrical grids, they are generally used to carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations; utility poles are used to support lower-voltage subtransmission and distribution lines that transport power from substations to electric customers. They come in a wide variety of shapes and sizes. Typical height ranges from , though the tallest are the towers of a span between the islands Jintang and Cezi in China's Zhejiang province. The longest span of any hydroelectric crossing ever built belongs to the powerline crossing of Ameralik fjord with a length of . In addition to steel, other materials may be used, including concrete and wood. There are four major categories of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typeface Anatomy
Typeface anatomy describes the graphic elements that make up letters in a typeface. Strokes The ''strokes'' are the components of a letterform. Strokes may be ''straight'', as in , or ''curved'', as in . If straight, they may be ''horizontal, vertical,'' or ''diagonal''; if curved, ''open'' or ''closed''. Typographers also speak of an ''instroke,'' where one starts writing the letter, as at the top of , and an ''outstroke,'' where the pen leaves off, as at the bottom of . A main vertical stroke is called a ''stem''. The letter has three, the left, middle, and right stems. The central stroke of an is called the ''spine''. When the stroke is part of a lowercase and rises above the height of an (called the x height), it is called an '' ascender''. Letters with ascenders are . A stroke which drops below the baseline is a ''descender''. Letters with descenders are . An arching stroke is called a ''shoulder'' as in the top of an or sometimes just an ''arch'', as in .
