Abstract: A communication device includes a first and second near-field wireless (NFW) module operating with a first and second protocol, respectively. A module and method to improve the operational efficiency of the first and second NFW modules are disclosed. Due to close proximity between the first and second NFW modules in the communication device, an undesirable parasitic inductive coupling can occur that can degrade the operational performance of the modules. The first NFW module can be configured to control inductive coupling of the second NFW module when an electromagnetic (EM) field operating with the first protocol is detected. Additionally, the second NFW module can be configured to control inductive coupling of the first NFW module when an EM field operating with the second protocol is detected. Controlling the inductive coupling of each module can be performed by means of detuning an inductive coupling element of each module.

Abstract: A charge stored in a battery is estimated by multiplying estimated charge currents supplied during charge phases and estimated discharge currents discharged during operational modes by the respective amounts of time of charging and discharge. The state of charge of the battery is calculated from the estimated stored charge. Furthermore, parameters of the battery may be measured to be used to adjust the estimated state of charge of the battery. In a first case, the estimated stored charge may be adjusted to a charge value corresponding to the detected completion of a constant current charge phase. In a second case, the estimated stored charge may be adjusted to a charge value corresponding to the detected completion of a constant voltage charge phase. In a third case, the estimated stored charge may be adjusted to a charge value corresponding to a detected predetermined discharge level of the battery.
