Abstract: An apparatus, system and method for determining whether a battery alarm of a UE is asserted, reducing a transmission duty cycle of the UE to zero for a first predetermined time period when the battery alarm is asserted, determining whether the battery alarm has been de-asserted after the first predetermined time period and when the battery alarm has not been de-asserted, increasing the transmission duty cycle to a first threshold level for a second predetermined time period, wherein the first threshold level is less than a full transmission duty cycle of the UE. When the battery alarm has been de-asserted, increasing the transmission duty cycle to a second threshold level for a third predetermined time period, wherein the second threshold level is less than the full transmission duty cycle of the UE, and wherein the second threshold level is greater than the first threshold level.

Abstract: A power system uses a power transmitting device to charge batteries in power receiving devices. Wireless power is transmitted using coils in the power transmitting device and coils in the power receiving devices. Usage history information such as power consumption, times and dates of device usage, battery charge state information, device location information, and other information is gathered using portable electronic devices in the system. Control circuitry in the power transmitting device or elsewhere in the system controls power transfer so that battery charging is performed in accordance with appropriate battery charging settings. Battery charging settings such as maximum charge level, charge rate, charging start and stop times, and other settings are adjusted based on usage history information from one or more devices and/or one or more users.
