To determine the movement of a device, a three-dimensional measurement of the device's acceleration is provided in known directions with regard to the device, and average signals (x, y, z) of acceleration signals (x, y, z) parallel to different axes are fo...

Disclosed is a method for charging a battery and circuitry for performing the method. The method includes steps of: (A) generating at a first node a battery charge current (Icharge) for charging the battery; (B) generating at a second node a replica curren...

Disclosed is a method for charging a battery and circuitry for performing the method. The method includes steps of: (a) generating a charging current (Ich) for a battery; (b) generating a replica current (Irep) of Ich, where Irep=Ich/N, where N > 1; (c) me...
