Dipole model of the Earth's magnetic field (MLAT), or geomagnetic latitude, formula_10 is measured northwards from the equator (analogous to geographic latitude) and is related to formula_9 by formula_12. In this case, the radial and azimuthal components of the magnetic field (the latter still in the formula_9 direction, measured from the axis of the north pole) are given by formula_14 formula_15 formula_16 where formula_17 in this case has units of Earth radii (formula_18). Invariant latitude is a parameter that describes where a particular magnetic field line touches the surface of the Earth. It is given by formula_19 or formula_20 where formula_21 is the invariant latitude and formula_22
Latitude ON Latitude ON Latitude ON is an instant-on computer system made by Dell. It is a combination of software and hardware developed by Dell and used in some of their Latitude laptops. The system is based on a dedicated ARM processor (Texas Instruments OMAP 3430) that runs a custom version of a Linux OS. It was announced on August 12, 2008 along with other laptops, including a potential competitor to the Asus Eee PC and arrived a year later on 28 September 2009. Latitude ON runs MontaVista Linux on an ARM-based subprocessor. This so-called MontaVista Montabello Mobile Internet Device Solution provides
