Abstract: According to one embodiment, a method for increasing resolution and accuracy of an analog to digital converter receiving an input voltage includes dithering a number of digital output values from the analog to digital converter to generate a number of dithered values. The analog to digital converter can be an 8-bit analog to digital converter, for example. The dithered values are then averaged to generate an average dithered value. For example, the dithered values can be averaged using a moving average technique. The average dithered value is then scaled down to generate a scaled value. Thereafter, the scaled value is mapped to a, for example, 10-bit digital output having higher resolution and higher accuracy than the raw 8-bit output of the analog to digital converter. In this example, the resolution of the analog to digital converter is increased by a factor of four.

Abstract: User information such as address books, calendars, images, ring tones, and the like may be exchanged between a mobile device such as, for example, a mobile phone and a personal computer, using an enhanced or extended version of an AT command set. Client code in the mobile device and application software on the personal computer permit a user to preserve and transfer copies of personal information via a short wired or wireless communication link, permitting the user to make use of such personal information when migrating to a new mobile device, thus avoiding manual re-entry of information, loss of stored images, and re-purchase of previously purchased and downloaded materials.
