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.
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.
Various popular RF connectors Electronic symbols for the plug and jack coaxial connectors Time-domain reflectometry shows reflections due to impedance variations in mated RF connectors. An RF connector ( radio frequency connector ) is an electrical connector designed to work at radio frequencies in the multi-megahertz range.
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.
Traffic Message Channel (TMC) is a technology for delivering traffic and travel information to motor vehicle drivers.It is digitally coded using the ALERT C or TPEG protocol into Radio Data System (RDS) [1] carried via conventional FM radio broadcasts.
1AG size, type AGA, 1 A to 30 A, 1 ⁄ 4 inch (6.4 mm) diameter by 5 ⁄ 8 inch (15.9mm) long [10] 2AG size, type AGB, 0.177 in (4.5 mm) diameter by 0.588 in (14.9 mm) long (frequently replaced with 5mm diameter by 15mm long international size fuse (aka 5 x 15mm - now more readily available) [15]
The outlet is connected directly to the electrical system of the car. The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts ...
Mobile players for physical media have been provided for vinyl records, 8-track tapes, cassette tapes, compact discs, and MP3s.The increased sophistication of the vehicle audio system to accommodate such media has made the audio unit a common target of car break-ins, so these are equipped with anti-theft systems too.
