Abstract

A personal mobility device, such as a wheelchair or a scooter, is disclosed. The personal mobility device includes at least one angle sensor to detect if the personal mobility device has overturned, and at least one accelerometer to detect if the personal mobility device has been struck in an accident. The angle sensor and the accelerometer sensor or coupled to a processor, and transmit data to the processor. A communication module is coupled to the processor and automatically signals a remote party for assistance when activated by the processor in response to an indication that the personal mobility device has overturned or been struck. The personal mobility device further includes a mast having a video device mounted atop thereof and in communication with a display to provide a video signal from an elevated position to the display, and a current sensor and a remote battery disconnect switch to reduce the potential for electrical fire.

a pair of non-pivotable wheels rotatably mounted to said frame for rotation about a second horizontal axis;

a motor coupled to said pair of non-pivotable wheels for driving said pair of non-pivotable wheels; and

a control mechanism coupled to said pair of non-pivotable wheels for controlling a speed and a direction of said device.

6. A device as set forth in claim 1 further comprising an input-output display coupled to said processing unit for entering commands into said processing unit and displaying data to the handicapped person.

7. A device as set forth in claim 5 further comprising a battery for powering said motor and said processing unit.

8. A device as set forth in claim 7 wherein said processing unit includes an internal backup battery.

9. A device as set forth in claim 1 further including an auxiliary input in communication with said processing unit for entering commands into said processing unit.

10. A device as set forth in claim 9 wherein said auxiliary input includes one of a group comprising a sip blow input, a joystick input, a voice activation input, a head mounted pointing input, a push button input, and a specialized keyboard input.

11. A device as set forth in claim 1 further comprising an emergency signal coupled to said communication module for manually activating said communication module to alert the remote party for assistance.

12. A device as set forth in claim 1 wherein said processing unit includes a modular mainframe computer including a plurality of slots for individually receiving a card providing additional functionality to said processing unit.

13. A device as set forth in claim 12 wherein said card includes one of a group comprising an extended vision card, an emergency response card, a television/radio card, and a wireless internet card.

14. A device as set forth in claim 13 further comprising a battery for powering said motor and said processing unit and at least one current sensor in communication with said processing unit for transmitting data to said processing unit to indicate a malfunction in said battery.

15. A device as set forth in claim 14 further comprising a switch in communication with and controlled by said processing unit for automatically disconnecting said battery upon receiving an indication of a malfunction in said battery from said current sensor.

16. A device as set forth in claim 13 further comprising a medical device attached to said frame and a medical device sensor in communication with said processing unit for transmitting data to said processing unit to monitor said medical device to indicate a medical emergency with the handicapped person and automatically activate said communication module to alert the remote party for assistance.

17. A device as set forth in claim 13 further comprising a motor coupled to said frame and at least one component sensor in communication with said processing unit for transmitting data to said processing unit to indicate a malfunction in said motor.

18. A device as set forth in claim 13 further comprising an input-output display coupled to said processing unit and a telescoping mast attached to said frame having a video apparatus disposed on top of said telescoping mast in communication with said processing unit for providing a video signal to said input-output display through said processing unit.
