Dual battery charger mobile communication apparatus

摘要

A positioning locator mobile communication apparatus securely attached to a person or a subject to be monitored, wherein said apparatus utilizes two internal batteries to provide power to the mobile communication device electronic circuitry, and a detachable battery is used to charge the internal batteries. Wherein when the first internal battery is being charged by the detachable battery, the mobile communication device is operative by the second internal battery power. And when the second internal battery is being charged by the detachable battery, the mobile communication device becomes operative by the first internal battery power. The positioning locator mobile communication apparatus may utilize the first internal battery, to provide power to the mobile communication apparatus certain components electronic circuitry, and the apparatus may contain a second rechargeable or non-rechargeable internal battery designed to provide power to the mobile communication apparatus at least one other electronic circuitry.

1. Dual battery charger mobile communication apparatus, utilizing a first and second internal rechargeable battery, and a detachable battery or other wireless power means used to charge said apparatus first and second internal battery, wherein said first and second internal battery is used to provide power to said apparatus electronic circuitry components, comprises:
a housing containing said first and a second internal rechargeable battery, at least one processor having a battery condition detection circuitry configured to detect low battery condition of said first and said second internal batteries, and a battery charging circuitry configured to charge said first and said second internal batteries, and a power switching circuitry configured to supply power from said first and second internal battery to said apparatus electronic circuitry, and a signaling circuitry, said processor in conjunction with an RF transceiver circuitry used to establish RF communication with other communication devices through a wireless communication network, said processor in response to received low battery detection signal, activates said apparatus signaling circuitry for the user to attach said detachable battery to said apparatus to charge said first or second internal low battery, wherein when said apparatus first internal battery is in low condition, and said second internal battery is charged to a set level, said processor low battery detection circuitry detects said first internal low battery condition, and sends a signal to said power switching circuitry to disconnect said first low condition battery from said apparatus electronic circuitry, and connect said first internal low battery to said battery charging circuitry to obtain power from said detachable battery and charge said first internal low battery, and said processor power switching circuitry connects said charged second internal battery to said mobile communication apparatus electronic circuitry, to provide power to said apparatus electronic circuitry from said second internal battery, thereafter when said second internal battery becomes in low condition, said processor in response to received second internal low battery condition signal, sends a signal to said power switching circuitry to disconnect said second internal battery from said apparatus electronic circuitry, and connect said second internal battery to said apparatus battery charging circuitry to obtain power from said detachable battery to charge said second low condition internal battery, and connect said first internal battery to said apparatus electronic circuitry to supply power to said apparatus electronic circuitry.
