发明名称 Adaptive power cycling for a cordless telephone
摘要 A cordless telephone provides for improved conservation of battery power in a handset unit when this unit is located remote from an associated base unit and in a standby state for a prolonged period of time. While the handset unit is in the standby state for less than a predetermined time period, this unit resides in a low-power monitoring mode which includes deactivating certain internal circuitry and reducing by a first time period the on-time state of other internal circuitry for conserving battery power. After being in the standby state for greater than the predetermined time period, the handset unit continues to reside in the low-power monitoring mode, but further reduces by a second time period the on-time state of the other internal circuitry for greater conservation of battery power. Communications between the handset unit and the base unit is easily reestablished by either one of these units irrespective of the time that the handset unit has been in the standby state.
