Abstract

A cellular telephone includes a multimedia card (MMC) having storage capacity for computer data files. An engagement device for a data transfer interface (e.g., a universal serial bus (USB) interface) is permanently mounted to the housing of the cellular telephone. The engagement device is movable from a nonobstructing home position to an extended position to allow a user to plug the cellular telephone directly into a computer or other data processing system without requiring addition cables or connectors. The MMC is configured and controlled by a microcontroller or other control device to emulate a solid-state drive such that a user has the full capabilities of a solid-state drive and a cellular telephone in a single convenient housing.

Claims

1. A cellular telephone comprising:

a housing;

electronic circuitry within the housing;

a connector for receiving a removable multimedia card and coupling the multimedia card to the electronic circuitry;

a data transfer interface coupled to the electronic circuitry;

an engagement device permanently mounted to the housing, the engagement device having a home position in which the engagement device does not extend from the housing, the engagement device moveable to an operational position in which the engagement device extends from the housing and is insertable directly into a data transfer port of a digital system to provide electrical communication to the data transfer interface; and

a control device coupled to the data transfer interface to receive data and commands via the engagement device, the control device controlling the transfer of data between the engagement device and the multimedia card.

2. The cellular telephone as defined in claim 1, wherein the data transfer interface is a universal serial bus (USB) interface and wherein the engagement device is a USB plug.

3. The cellular telephone as defined in claim 1, wherein the USB engagement device in the operational position extends from top of the housing.

4. The cellular telephone as defined in claim 1, wherein the USB engagement device in the operational position extends from the back of the housing.

5. The cellular telephone as defined in claim 1, wherein the USB engagement device in the operation position extends from the housing via a flexible cable.

6. The cellular telephone as defined in claim 1, wherein the USB engagement device in the home position is recessed within the back of the housing.

7. The cellular telephone as defined in claim 1, wherein the control device transfers data between the data transfer interface and the multimedia card in accordance with a USB solid-state drive protocol.

8. The cellular telephone as defined in claim 1, wherein the cellular telephone includes a power supply coupled to a battery, and wherein the power supply couples power from the engagement device to charge the battery.

9. A method for using a cellular telephone as a solid-state drive for a computer system, comprising:

inserting a multimedia data storage card in a receptacle within the housing of the cellular telephone;

moving a USB engagement device permanently attached to the housing of the cellular telephone from a home position to an operational position;

inserting the USB engagement device into a USB port of the computer system; and

transferring data between the computer system and the multimedia data storage card.

10. The method as defined in claim 9 further comprising selectively displaying on a display of the cellular telephone a listing of files stored in the multimedia data storage card.

11. A multifunction cellular telephone comprising:

a housing;

a keypad;

a microphone;

a speaker;

electronic circuitry within the housing responsive to signals from the keypad to establish a radio frequency communication link to operate the cellular telephone in a cellular communication mode;

a removable multimedia card within the housing for storing digital data;

a USB interface within the housing coupled to the multimedia card; and

a USB engagement device permanently attached to the housing, the USB engagement device moveable from a home position to an operational position, the USB engagement device in the operational position being insertable into a USB port of a computer system to enable data transfers between the computer system and the multimedia card to operate the cellular telephone in a solid-state drive mode.
