Such functionality could also be carried out via dedicated hardware or a combination of hardware and logical instructions (e.g., firmware and/or software).
The electronic circuitry 20 may further include a radio circuit 24 that is coupled to an antenna 26. For instance, the radio circuit 24 may include a radio frequency transmitter and receiver for exchanging signals with the communications network 14 (or directly with an electronic device) via the antenna 26. As indicated, the radio circuit 24 may be configured to operate in a mobile communications system and may be used to send and receive data (including, for example, audio content to carry out a call and/or video content). Radio circuit types for interaction with a mobile radio network and/or broadcasting network include, but are not limited to, GSM, CDMA, WCDMA, GPRS, MBMS, WiFi, WiMax, DVB-H, ISDB-T, etc., as well as advanced versions of these standards.
The electronic circuitry 20 may further include an interface circuit 28 that couples the control circuit 22 to an electrical connector, which is referred to herein as a plug 30. The plug 30 may be used to establish physical and electrical connection between the accessory 10 and the electronic device 12. In the illustrated embodiments, the plug 30 is a plug constructed in accordance with one or more of the Universal Serial Bus (USB) standards. It will be appreciated that the plug 30 may be another type of connector, such as a connector constructed in accordance with IEEE Standard 1394 (e.g., Firewire), a connector constructed in accordance with some other standard or a proprietary connector. The interface circuit 28 may be an interface controller. For instance, in the embodiment where the plug 30 is a USB plug, the interface circuit 28 may be a USB controller.
The electronic circuitry 20 may further include an interface circuit 32 that couples the control circuit 22 to a removable component 34. In the illustrated example, the removable component 34 is a subscriber identity module (SIM) card. As will be appreciated, a SIM card may include a memory component and may be used to securely store information that identifies a mobile phone service subscriber, as well as subscription information, saved telephone numbers, preferences, text messages and other information. The SIM card may store network state information such as a current location area identity (LAI). The SIM card may be uniquely identified by an international circuit card identifier (ICCID) and may uniquely identify a user with an international mobile subscriber identity (IMSI). Other types of removable components that serve similar purposes may be used. For instance, a universal subscriber identity module (USIM) for use with a universal mobile telecommunications system (UMTS) may be employed.
As indicated, the illustrated accessory 10 is a communicator, and, more specifically, a USB modem with an integrated SIM card holder. When the accessory 10 with the SIM card is “plugged” into a corresponding receptacle 36 (FIG. 1) of the electronic device 12, the electronic device may communicate with the communications network 14 or another device. The resulting communications link may be used to carry out related functions, such as exchanging information, conducting conventional circuit switched calls or packet switched calls (e.g., voice over internet protocol or VoIP calls), accessing the Internet and so forth.
The accessory 10 may be other types of devices and/or may include components to carryout functions in addition to communicator functions. In one embodiment, the accessory 10 may be a memory device where the radio circuit 24 and the antenna 26 are omitted and the removable component is a removable memory card, such as a flash memory card.
With additional reference to FIGS. 3 and 4, the accessory 10 may have a housing 38 from which the plug 30 extends. A movable member 40 may be secured to the housing 38 so that the movable member 40 is not readily removable from the housing 28. The housing 38 and the movable member 40 may be made from a molded polymer material, for example. In the illustrated embodiment, the movable member 40 is hinged to the housing and, in FIG. 3, is shown in an open position. The movable member 40 may be swung to a closed position as shown in FIG. 4. A recess 42 in the housing 38 may accommodate the movable member 40 when the movable member is in the closed position.
In the illustrated embodiment, a distal end of the movable member 40 includes plug cover 44. The plug cover 44 has one or more walls 46 that are perpendicular to the moveable member 40. When the movable member 40 is moved to the closed position, the walls 46 slide over and engage opposing side surfaces of the plug 30 and an open end of the plug 30. In the illustrated embodiment of the plug 30, the plug 30 is configured as a series A USB plug. In such a configuration, the sides of the plug 30 together with a top and a bottom form a cavity in which electrical connectors are positioned. Other types of plugs may have similar cavities and/or open ends. The wall 46 that covers the open end of the plug 30 may reduce the possibility of a foreign object entering the cavity and damaging the plug 30. One or more of the walls 46 may have a detent 48 that snap fits over the plug 30 to assist in retaining the movable member 40 in the closed position. A lifting force may be applied to the movable member 40 to disengage the detent 48 from the plug 30.
As will be appreciated, the cover 44 may cover the plug 30 when the accessory 10 is not in use. The cover 44 is affixed to the housing 38 through the hingably connected movable member 40 to reduce the possibility of the cover 44 becoming lost. Also, the cover 44, when positioned over the plug 30, may physically interfere with establishing a connection between the plug 30 and the receptacle 36.
In one embodiment, the antenna 26 (FIG. 2) may be disposed within the movable member 40. One or more electrical conductors that run through the hinge connection between the movable member 40 and the housing 38 may couple the antenna 26 to the radio circuit 24. In one embodiment, the electrical conductors may be arranged so that electrical connection between the antenna 26 and the radio circuit 24 is established when the movable member 40 is in the open position and so that the electrical connection is disengaged when the movable member 40 is in the closed position. Integrating the antenna 26 with the movable member may improve the wireless communication link with the communications network 14 or another device by allowing the user to move the antenna 26 to optimize the signal strength. In another embodiment, the antenna 26 may be disposed in the housing 38.
With additional reference to FIGS. 5 and 6, the accessory 10 may include another moveable member 50. The movable member 50 may be secured to the housing 38 so that the movable member 50 is not readily removable from the housing 28. It will be understood that the accessory 10 may include just one of the movable members 40 or 50, or both movable members 40 and 50 (e.g., as best shown in FIG. 4). The movable member 50 may be made from a molded polymer material, for example.
The movable member 50 may serve to cover a receptacle 52 for the removable electronic component 34. In the illustrated embodiment, the receptacle 52 is a card holder that mechanically receives a SIM card and establishes an electrical interface thereto. The movable member 50 may move between an open position as shown in FIG. 6 and a closed position as shown in FIGS. 4 and 5. One or more detents 54 may interact with a corresponding structure (e.g., indent or detent) of the movable member 50 to assist in maintaining the movable member 50 in the closed position. Also, one or more detents 56 may interact with a corresponding structure (e.g., indent, detent or a trailing edge 58) of the movable member 50 to assist in maintaining the movable member 50 in the open position. Detents 60 on the trailing edge of the movable member 50 may be received in corresponding indents 62 of the housing and may form a friction, snap or interference fit therewith.
When in the open position, a user may remove and/or insert the removable component 34 with respect to the receptacle 52. When the removable component 34 is inserted into the receptacle 52 and the movable member 50 is closed, the removable component 34 may be considered to be fully contained within the accessory 10.
When in the open position, a forward portion of the movable member 50 may cover the plug 30 as best shown in FIG. 6. In this position of the movable member 50, the plug 30 may not be inserted into the corresponding receptacle 36 unless the movable member 50 is first closed. That is, when the movable member 50 is in the open position so as to provide user access to the receptacle 52, the movable member 50 may physically interfere with insertion of the plug 30 into to receptacle 36.
In addition, when the plug 30 is inserted into the receptacle 36 so as to establish an interface between the accessory 10 and the electronic device 12, user access to the receptacle 52 is minimized. That is, when the movable member 50 is in the closed position, the receptacle 52 is covered and the plug 30 is uncovered to allow insertion of the plug 30 into the receptacle 35. Furthermore, a housing or other structural component of the electronic device surrounding the receptacle 36 will interfere with opening of the movable member 50. In particular, a leading edge 64 of the movable member 50 will engage the electronic device 12 to interfere with opening of the movable member 50.
It will be appreciated that the arrangement of the movable member 50, the plug 30 and the receptacle 52 minimizes the possibility that the user may insert or remove the removable component 34 when the accessory 10 is interfaced with the electronic device 12 and possibly receiving operating power from the electronic device 12. As such, the physical configuration of the accessory 10 reduces the risk of damage to the removable component 34, the accessory 10 and/or the electronic device 12 by insertion or removal of the removable component 34 at an inopportune time.
It will be appreciated that the illustrated and described embodiments are exemplary representations of techniques for covering the plug 30 and/or minimizing removal of the removable component 34 when the plug 30 is inserted into the receptacle 36. Other implementations are possible. The invention is not limited by the illustration and description of exemplary representations. For example, another possible embodiment is to couple a slidable or rotatable movable member with a finger that extends next to the plug 30 or through the cavity of the plug 30. The movable member may selectively cover the receptacle 52 and the finger may create an interference with the electronic device 12 or the receptacle 36 to minimize access to the receptacle 52 when the plug 30 is inserted into the receptacle 36. In another embodiment, the movable member may move in multiple directions or manners. For instance, the movable member may be moved by lifting and sliding the movable member.
In another embodiment, the movable member 50 may not create or cause a mechanical interference between the accessory 10 and the electrical device 12. Rather, movement of the movable member to allow access to the receptacle 52 may result in an electrical disconnection of power and/or signals between the interface circuit 32 (FIG. 2) and the removable component 34. For instance, the movable member 50 may be coupled to a switch that is toggled by movement of the movable member 50. The switch may control the application or power and/or signals to the removable component 34. As another example, the position of the movable member 50 and/or movement of the movable member 50 may be sensed to control the application or power and/or signals to the removable component 34. Position and/or movement sensing may be made by using, for example, a Hall effect sensor and a magnet, or an accelerometer.
Although the invention has been shown and described with respect to certain preferred embodiments, it is understood that equivalents and modifications will occur to others skilled in the art upon the reading and understanding of the specification. The present invention includes all such equivalents and modifications, and is limited only by the scope of the following claims.
