Abstract

A portable power source and control device for a mobile phone or tablet is releasably attachable to a user'"'"'s key ring or key chain and sized to be carried in a pocket or purse. The device has an internal rechargeable battery to provide emergency power for operating the user'"'"'s phone, USB connectors for connection a power source and the phone, an internal microcontroller, and a Bluetooth® wireless communicator. A user actuator generated a locator command causes the phone to ring to indicate its location; and a locator command from the phone causes the device to emit a sound to indicate the device'"'"'s location. The device can determine and indicate via LEDs the charge level of the battery, and has flash memory for data storage and transfer between devices.

Claims

1. A portable mobile phone power and control device comprising:

a housing having a rechargeable battery therein;

a first connector for connection to a power source for recharging said rechargeable battery within the housing;

a second connector for supplying power from said rechargeable battery to a drained internal battery of the mobile phone, the second connector being on a cable that is stored by the housing when the second connector is not connected to the mobile phone; and

a user operable sliding latch within the housing for releasably capturing a key ring of the user within a cutout formed in the housing to attach the device to said key ring, wherein said cutout is located in an external surface of the housing and has a semi-spherical configuration, and said sliding latch is movable within an internal slot within the housing and biased by a spring to close an opening of said cutout to capture the key ring therein, and wherein said housing has a slot located in an external surface thereof, and said cable and second connector are retained in said slot for storage.

5. The device of claim 1 further comprising electronic circuitry within said housing, said electronic circuitry comprising a battery charger for controlling the recharging of said rechargeable battery, and a microcontroller having executable instructions contained within firmware for controlling the operation of the microcontroller, said microcontroller being operable to determine a charge level of said in rechargeable battery, and for indicating the charge level by an indicator on said housing.

6. The device of claim 5, wherein said electronics circuitry comprises an accelerometer for measuring and characterizing a force exerted on the device by movement caused by a user'"'"'s gesture, and for actuating said microcontroller in response to a predetermined gesture to determine and indicate said charge level, wherein said predetermined gesture comprises a shaking of the device by the user.

8. The device of claim 6, wherein said accelerometer and microprocessor determine magnitudes and directions of forces on the device in three dimensions, and interpret different force characteristics as corresponding to different commands.

9. The device of claim 5, wherein said electronic circuitry further comprises a low drop out regulator for supplying power to said electronics circuitry at low current, and a switching regulator for supplying power at high current.

10. The device of claim 5, wherein said electronics circuitry further comprises a wireless communicator for communicating commands between said device and said mobile phone to perform predetermined operations.

11. The device of claim 10, wherein said commands comprise a first command sent in response to actuation by a user of an actuator on the device to cause said mobile phone to emit an audible signal to indicate a location of the mobile phone.

12. The device of claim 11, wherein said mobile phone has an application responsive to a periodic heartbeat signal sent by the device to cause the mobile phone to update and store its current GPS location, and the application is responsive to a user input command to indicate said stored GPS location on a map on a display of said mobile phone to indicate a last location of the device.

13. The device of claim 1 further comprising non-volatile flash memory within the housing for storing and transferring data between said mobile phone and another data source.
