Abstract

A mobile communication apparatus utilizes a first and a second internal battery to provide power to the apparatus'"'"' electronic circuitry. A detachable battery may charge the first internal battery, and the first internal battery may provide power the electronic circuitry and charge the second internal battery. When the first internal battery is being charged by the detachable battery, the apparatus is operative by the power from the second internal battery. And, when the second internal battery is being charged by the first internal battery, the apparatus becomes operative by the power from first internal battery. The apparatus further may include a positioning locator receiver used to determine the location of the apparatus, and may be securely attached with a tamper detection circuitry to a person or a subject to be monitored.

Claims

1. Automatic dual battery charger mobile communication apparatus, comprising:

a first internal battery and a second internal battery, wherein the first internal battery charges the second internal battery, and concurrently, provides power to electronic circuitry of the apparatus;

a detachable battery configured to charge the first internal battery;

a housing comprising the first internal battery and a second internal rechargeable battery, the detachable battery attached to, or inserted into, the housing to charge the first internal battery;

a processor comprising a low battery detection circuitry configured to detect low battery condition of the first internal battery and the second internal battery;

battery charging circuitry configured to charge the first internal battery and the second internal battery, and a power switching circuitry configured to supply power from the first or second internal battery to the apparatus electronic circuitry;

low battery detection signaling circuitry; and

radio frequency (RF) transceiver circuitry configured to establish RF communication with other communication devices through a wireless communication network, wherein

when the first internal battery provides power to the electronic circuitry, the battery charging circuitry is configured to obtain power from the first internal battery and charge the second internal battery, and

the low battery detection circuitry, upon detecting of a low battery condition for the first internal battery, causes the processor to activate the low battery detection signaling circuitry notifying the user to attach the detachable battery to or into the housing allowing for the battery charging circuitry to obtain power from the detachable battery to charge the first internal battery, and concurrently, the power switching circuitry is configured to provide power from the second internal battery to the electronic circuitry.

2. The apparatus of claim 1, further comprising:

a positioning locator receiver configured to receive coordinate signals from global positioning system (GPS) satellites to coordinate the location of the apparatus, and to transmit the received coordinate signals to a monitoring station, or

the RF transceiver circuitry receives signals from cell/radio towers to coordinate the location of the apparatus, and transmit the received coordinate signals to the monitoring station.

3. The apparatus of claim 2, further comprising:

a tamper detection housing securely attached to a subject to be monitored, wherein

the tamper detection housing is configured to detect housing tamper or removal of the housing from the subject to be monitored, and the processor of the apparatus, in response to detecting a tamper condition, causes the RF transceiver circuitry to transmit at least one signal to the monitoring station, wherein the at least one signal comprises an identification of the apparatus, the identification of the apparatus and a condition of the apparatus, the identification of the apparatus and positioning location information of the apparatus, or the identification of the apparatus, the condition of the apparatus, and the positioning location information of the apparatus.

4. The apparatus of claim 2, further comprising:

a housing securely attached to a subject to be monitored with a removal tamper sensor, by a removal tamper detection strap, or both, wherein

the processor of the apparatus, in response to detecting the tamper condition, causes the RF transceiver circuitry to transmit at least one signal to a monitoring station, the at least one signal comprising an identification of the apparatus, the identification of the apparatus and a condition of the apparatus, the identification of the apparatus and positioning location information of the apparatus, or the identification of the apparatus, the condition of the apparatus, and the positioning location information of the apparatus.

5. The apparatus claim 1, wherein

when the low battery detection circuitry detects that the first internal battery is at a preset low level condition, the battery charging circuitry automatically charges the first internal battery when the detachable battery is attached to the apparatus.

6. The apparatus of claim 1, wherein

the low battery detection circuitry, in response to detecting a low condition for the second internal battery, causes the processor to transmit one or more signal to a monitoring station indicative that the second internal battery is in the low condition.

7. The apparatus of claim 1, wherein

when the low battery detection circuitry detects that the first internal battery or second internal battery is not charging, the processor activates the low battery detection signaling circuitry to notify the subject to be monitored that the first internal battery or the second internal battery is exhausted and not holding charge, or transmit a signal to a monitoring station indicating that the first internal battery or the second internal battery is exhausted and not holding charge, or both.

8. The apparatus of claim 1, wherein,

when the detachable battery is low, the low battery detection circuitry detects a low condition of the detachable battery and activates the low battery detecting signaling circuitry indicating to the user that the detachable battery has reached a set low power level, instructing the user to replace or detach and charge the detachable battery.

9. The apparatus of claim 1, wherein

when the battery charging circuitry obtains power from the detachable battery to charge the first internal battery, and when the detachable battery is exhausted or removed prior to fully charging the first internal battery, the processor activates the low battery detection signaling circuitry to alert the user that the detachable battery, the first internal battery, or both is not fully charged;

and for the user to insert a charged detachable battery to charge the first internal battery.
