The invention concerns a system () and method () for charging a battery. The method includes the steps of supplying () a charging current to a battery (), sensing () the charging current to the battery and selectively signaling () an electronic device () from the battery to indicate at least one parameter of the battery as the battery is receiving the charging current. As an example, the charging current can be from a wireless charger (). In addition, the parameter can be, for example, a charging state of the battery or a predetermined current threshold of the charging current.

Method and system for wireless charging

A portable electronic device and a method to protect the portable electronic device from a battery bounce are provided. The portable electronic device () can comprise a free-fall condition sensor () enabled to detect a pre-battery bounce condition in the portable electronic device and a processor () coupled to the free-fall condition sensor (). The processor (), in response to a detection of the pre-battery bounce condition by the free-fall condition sensor (), can be programmed to place the portable electronic device () in a pre-battery bounce setting. The method can include detecting a pre-battery bounce condition in the portable electronic device () and in response to the detection of the pre-battery bounce condition (), placing the portable electronic device in a pre-battery bounce setting ().

Portable electronic device and method to protect same

This invention is a single wire interface communication system whereby a phone having internal charging circuitry communicates the charging status of the battery attached to the phone by varying the duty cycle of a pulse with a predetermined period across the single wire interface. In a preferred embodiment, the predetermined pulse of time T, where T is 1 second, is divided into N divisions, where N equals 10. A duty cycle high for time T/N and low for time 9T/N represents a first charging state; a duty cycle high for time 2T/N and low for time 8T/N corresponds to a second charging state; and so on. The system allows for information to be transmitted across a single wire, thereby freeing data connections for other accessories.
