- The present invention will be more fully understood and appreciated from the following detailed description, taken in conjunction with the drawings in which:
-
FIG. 1 is a simplified block diagram of a communication card with three operational states, in accordance with a first embodiment of the present invention; and -
FIG. 2 is a simplified flowchart of a method for a communication card to detect the type of device it is connected to, in accordance with an embodiment of the present invention. - The present invention relates to a communication card that is operable in three states; namely, (I) a standalone state, (II) a state connected to a simple host, and (III) a state connected to a complex host. In State II the simple host is a shell. The communication card operates as a master and the shell operates as a slave. Conversely, in State III the complex host is a consumer electronics (CE) device.

The communication card supplies power to the shell's keyboard, display speakers and microphone, and to the card's own internal circuitry. The communication card uses the shell's secondary power source to charge the card's internal power source.

Commands and information are shared, and sent over an SD control bus during operation. The CE device includes its own CPU, user interface and power source. The user interface for both the device functionality and the communication card functionality operates through the CE device. The interface to the CE device is via the communication card connector, where pins on the connector have specifically assigned functionalities and use specific protocols.
- It will thus be appreciated by those skilled in the art that the interface to the shell is via the same communication card connector as is the interface to the CE device, but the pins on the connector generally have different functionalities and use different protocols with the shell than those used with the CE device.
- The three operational states of the communication card are summarized in TABLE I hereinbelow.
-
TABLE I Three Operation States of a Communication Card State I Standalone Card uses its own interface State II Connected to a Card is master; Shell is slave simple host Shell cannot operate without card Card provides shell with screen shots, in the form of bitmap images, for display information Communication is through SD bus State III Connected to a Card is slave; CE device is master complex host CE device operates independently of card Card provides shell with screen shots, in the form of bitmap images, for display information Communication is through SD bus - Reference is now made to
FIG. 1 , which is a simplified block diagram of a communication card with three operational states, in accordance with a first embodiment of the present invention. As shown inFIG. 1 , acommunication card 100 includes aconnector 105, acontroller 110, aflash storage unit 115, abattery subsystem 120, aUSB connector 125 and a modem &applications processor 130.Modem 130 includes a radio frequency (RF)interface 135 and anaudio player 140. Wireless modem is coupled with aninput device 145, which is a small keyboard, and anoutput device 150, which is a small display. - Also shown in
FIG. 1 is ahost device 160 with ahost connector 165 that may be connected to thecommunication card connector 105. In accordance with an embodiment of the present invention,device 160 may be a shell and may be a CE device. - It will be appreciated by those skilled in the art that
communication card 100 supports the three operational states in TABLE I. Components 105-150 enablecommunication card 100 to function as a standalone device. Whenhost 160 is connected tocommunication card 100,communication card 100 may operate as a master or as a slave, and the SD communication betweenconnectors communication card 100 is the master andhost 160 is the slave, and in State IIIcommunication card 100 is the slave andhost 160 is the master. - In accordance with an embodiment of the present
invention communication card 100 automatically detects its operational environment by monitoring the voltage on designated pins on the connector. I.e.,communication card 100 distinguishes between States I-III based on voltage. CE devices and shells generally drive the voltage on these pins differently, which enablescommunication card 100 to discriminate whether or not it is connected todevice 160, and to detect the type ofdevice 160 it is connected to. - In this regard, reference is made to
FIG. 2 , which is a simplified flowchart of a method forcommunication card 100 to detect the type ofhost 160 it is connected to, in accordance with an embodiment of the present invention. Atstep 210controller 105 monitors the connector signal VBat_host, shown inFIG. 1 . If the VBat_host signal has a voltage level higher than logical zero (i.e., 0.5V or higher), as determined atstep 220, thencontroller 105 concludes thatcommunication card 100 is connected tohost 160. Otherwise, if VBat_host is logical zero (i.e., below 0.5V), then atstep 230controller 105 concludes thatcommunication card 100 is not connected to a host. As such, it will be appreciated by those skilled in the art that whenhost 160 is attached tocommunication card 100,controller 105 detects this by monitoring VBat_host. - In order to detect which type of
host 160 is connected tocommunication card 100,controller 105 monitors the HOST INT/TYPE signal, shown inFIG. 1 . When connection to a host is detected, the HOST_INT/TYPE signal is sampled atstep 240. If HOST_INT/TYPE is a logical zero (i.e., below 0.5V), as determined atstep 250, then atstep 260 the controller concludes thathost 160 is a simple shell. Otherwise, if HOST_INT/TYPE is higher than logical zero (i.e., 0.5V or higher), then atstep 270 the controller concludes thathost 160 is to a CE device. - The functionality of HOST_INT/TYPE for detecting the type of
host 160, is used when at thetime host 160 is attached tocommunication card 100. Afterwards, the signal HOST_INT/TYPE is used as an interrupt signal. - In an alternative embodiment of the present invention, the SD_Vdd signal, shown in
FIG. 1 , may be monitored atstep 210 instead of or in addition to the VBat_host signal. Whereas the VBa_host signal generally indicates whether or notcommunication card 100 is connected tohost 160, the SD_Vdd signal generally indicates whether or nothost 160 is turned on. - It will be appreciated by those skilled in the art that the threshold of 0.5V used in the above discussion is merely indicative of a general pre-designated threshold that is used to detect attached of the host to the communication card, and to detect the type of the host.
- When
communication card controller 105 detects connection to a CE device or a shell, the internal user interface ofcommunication card 100 is disabled atstep 280. For CE devices,communication card controller 105 receives user interface inputs, and provides feedback as bitmap graphics BMP screen shots, or as single messages, via the secure digital (SD) card bus. The CE device controls the device's display and keyboard. For shell devices, the communication card controller receives direct keyboard strokes on the shell keyboard over an SD bus, and provides the displayed image pixels/characters directly to the shell display over the SD bus. - In an embodiment of the present invention, in order to be powered, shells connect their internal circuitry to the Vbat_CC signal that connects to
connector 105. If ashell 160 has a secondary battery, then the secondary battery is connected to Vbat_Host, which connects to communication card'sbattery subsystem 120 and is used to charge the communication card's internal battery. - Similarly, the internal circuitry of a
CE device 160 is powered by connecting its internal power source to Vbat_Host.CE device 160 does not use the Vbat_CC signal as a power source, but may monitor it to detect whencommunication card 100 is connected thereto, or to monitor the communication card's battery level. - In the foregoing specification, the invention has been described with reference to specific exemplary embodiments thereof. It will, however, be evident that various modifications and changes may be made to the specific exemplary embodiments without departing from the broader spirit and scope of the invention as set forth in the appended claims. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
