20090053920
The present invention relates generally to the field of electronic devices and, more particularly, to electronic devices adapted to have removable electronic cards inserted therein.
Many communication devices, such as cellular telephones and wireless modems, are provided with an electronic card which may include data or software. Typically, such electronic cards may include identification information for identifying the device or the user to a network or another device. For example, many such devices include a subscriber identity module (SIM) card.
In many devices, this electronic card is removable. However, inadvertent removal of the card can cause many difficulties. For example, if a SIM card is removed from a wireless modem on a personal computer, the personal computer may require rebooting or reconfiguring.
In one aspect of the invention, an electronic device includes a connector for interfacing with a host device and an electronic card receiving portion. The electronic card receiving portion is configured to inhibit physical removal of an electronic card therein when the connector is interfaced with the host device.
In one embodiment, the electronic card receiving portion is part of a housing. The housing may be formed of molded plastic or plastic extruded on or attached to a metal. The electronic card receiving portion may be an insert secured within the housing. The insert may be formed of an amorphous alloy.
In one embodiment, the electronic card receiving portion includes tracks along which the electronic card can be inserted or removed.
In one embodiment, the electronic card receiving portion includes a card ejection slot adapted to facilitate removal of the electronic card.
The connector may be a universal serial bus (USB) connector. The electronic card receiving portion is positioned such that an electronic card inserted therein is positioned above or below the USB connector.
In one embodiment, the electronic card receiving portion is adapted to receive a subscriber identity module (SIM) card.
In another aspect of the invention, a modem device includes a universal serial bus (USB) connector for interfacing with a host device and an electronic card receiving portion. The electronic card receiving portion is configured to inhibit physical removal of an electronic card therein when the USB connector is interfaced with the host device.
In another aspect, the invention relates to a modem system. The system includes a universal serial bus (USB) connector for interfacing with a host device, an electronic card receiving portion, and an electronic card removably positioned within the electronic card receiving portion. The electronic card receiving portion is configured to inhibit physical removal of the electronic card therein when the USB connector is interfaced with the host device.

The electronic device 100 includes an upper housing 110 inside which the various components of the electronic device 100 may be secured. For example, electronic components necessary for the operation of the modem device, such as printed circuit boards with power centers, processors and antennas, may be secured within the upper housing 110. The upper housing 110 may be made of a variety of materials. In one embodiment, the upper housing 110 is formed of molded plastic or plastic extruded on or attached to a metal, such as an amorphous alloy (e.g., Liquidmetal®).
The upper housing 110 is provided with two sets of openings 112, 114. The first set of openings 112 is adapted to provide ventilation for the electronic device 100. In this regard, the ventilation may be passive. Additionally, a second set of openings 114 is provided to facilitate configuration (or reconfiguration) of the electronic device. For example, the set of openings 114 may be opening for Joint Test Action Group (JTAG) pins. The set of openings 114 may allow for configuration of the modem device for specific uses, for example.
In the illustrated embodiment, the electronic device 100 is provided with a connector 120 for interfacing the electronic device 100 with another device (not shown), such as a host device. In this regard, a host device may be any of a variety of devices, including communication devices. For example, in the case of wireless modem device, the electronic device 100 may be interfaced with a host device such as a desktop computer, a laptop computer, a personal digital assistant or the like. In this regard, when interfaced with a host device, the electronic device 100 provides wireless communication capability to allow the host device to communicate with, for example, a network such as a wireless local area network (WLAN), a cellular network or another device. In the illustrated embodiment, the connector 120 is a universal serial bus (USB) connector.

In order to facilitate insertion and ejection of the electronic card 130 into or out of the electronic card receiving portion 113, the electronic card receiving portion 113 may be provided with tracks 115 formed on the outer edges. In this regard, the edges of the electronic card 130 may slide on the tracks 115 for proper insertion and ejection.
Referring now to
When the electronic device 100 is to be connected to a host device (not shown), the connector 120 is interfaced with the host device by insertion of the connector 120 into a corresponding port of the host device. Thus, when the connector 120 is interfaced with the host device, physical removal of the electronic card in the electronic card receiving portion is inhibited. In this regard, when the connector 120, such as a USB connector, is inserted into a corresponding port, such as a USB port, movement of the electronic card 130 is restricted by the physical structure of the host device.
When removal of the electronic card 130 is desired, the user must first disengage the electronic device 100 from the host device. The user may then eject the electronic card 130 from the electronic card receiving portion 113 by inserting an object into the card ejection slot 116 and urging the electronic card 130 outward.
Thus, by requiring disengagement of the electronic device 100 from the host device, accidental or inadvertent removal of the electronic card 130 is avoided.
The foregoing description of embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the present invention to the precise form disclosed, and modifications and variations are possible in light of the above teachings or may be acquired from practice of the present invention. The embodiments were chosen and described in order to explain the principles of the present invention and its practical application to enable one skilled in the art to utilize the present invention in various embodiments and with various modifications as are suited to the particular use contemplated.
