Abstract
A tablet cover (100) and circuitry (400) provide for convenient connection of a tablet (105) or other personal electronic device to additional memory, functions, and features as provided by an internal device (215) and/or an external device (160). The circuitry selectively connects the tablet, the external device, and the additional memory together. The additional memory is internal to the case and is thereby protected from loss or damage due to accidental impact.
Claims15
An apparatus to provide at least one of an additional functionality or an additional feature to a personal electronic device, the apparatus comprising:
- a case to at least partially enclose the personal electronic device;
- a first port appearing on the surface of the case;
- a second port internal to the case and adapted to interface with a first port on the personal electronic device;
- an expansion device which provides the at least one additional functionality or additional feature;
- and
- a switching circuit connected to the first port of the case, the second port, and the expansion device, to selectively connect two or more of the first port of the case, the second port, and the expansion device to each other.
An apparatus to provide at least one of an additional functionality or an additional feature to a personal electronic device, the apparatus comprising:
- a case to at least partially enclose the personal electronic device;
- a first port appearing on the surface of the case;
- a second port internal to the case and adapted to interface with a first port on the personal electronic device;
- an expansion device which provides the at least one additional functionality or added feature;
- a switching circuit connected to the first port of the case, the second port, and the expansion device, and responsive to a voltage on at least one pin on the first port of the case to selectively connect two or more of the first port of the case, the second port, and the expansion device to each other;
- and
- a circuit board contained within the case, and wherein at least one of the first port of the case, the second port, the expansion device, or the switching circuit is mounted on the circuit board.
An apparatus, comprising:
- a personal electronic device having a first port;
- a case to at least partially enclose the personal electronic device;
- a first port appearing on the surface of the case;
- a second port internal to the case and connected to the first port on the personal electronic device;
- an expansion device which provides at least one of an additional functionality or an additional feature to the personal electronic device;
- a switching circuit connected to the first port of the case, the second port internal to the case, and the expansion device, and responsive to a voltage on at least one pin on the first port of the case to selectively connect two or more of the first port of the case, the second port, and the expansion device to each other;
- and
- a circuit board contained within the case, and wherein at least one of the first port of the case, the second port, the expansion device, or the switching circuit is mounted on the circuit board;
- wherein the first port of the case is offset from the first port of the personal electronic device.
