An original standard head unit size is ISO 7736, developed by the Deutsches Institut für Normung (DIN): Single DIN (180 mm × 50 mm or 7.09 in × 1.97 in) in Europe, South America, and Australasia A compact size that easily fits into a dashboard, but the unit is not tall enough to accommodate a video display.
This list of car audio manufacturers and brands comprises brand labels and manufacturers of both original equipment manufacturer (OEM) and after-market products generally related to in-car entertainment that already have articles within Wikipedia. While components sold by these companies have much in common with other audio applications or may ...
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
A nanowire battery uses nanowires to increase the surface area of one or both of its electrodes, which improves the capacity of the battery. Some designs (silicon, germanium and transition metal oxides ), variations of the lithium-ion battery have been announced, although none are commercially available.
In circuit diagrams, the symbol for a variable component is the symbol for a fixed component with a diagonal line through it terminating in an arrow head. For a preset component, the diagonal line terminates in a bar. [3]: 86, 97
A nanowire is a nanostructure in the form of a wire with the diameter of the order of a nanometre (10 −9 m). More generally, nanowires can be defined as structures that have a thickness or diameter constrained to tens of nanometers or less and an unconstrained length.
Recent experiment on nanowire solar cells has led to a remarkable improvement of the power conversion efficiency of SiNW solar cells from <1% to >17% in the last few years. [5] The ability for lithium ions to intercalate into silicon structures renders various Si nanostructures of interest towards applications as anodes in Li-ion batteries ...
