## Title
Device configuration including a master communications device with a slave device extension

## Abstract

A master communications device/slave device configuration is disclosed where a master communications device discovers a slave device when the master communications device does not have the necessary features and resources to perform a service requested by an operator. The master communications device utilizes the slave device to provide additional features and resources to the master communications device in performing the service requested by the operator. The master communications device and the slave device interact as a single device provided by the master communications device/slave device configuration. The slave device serves as an extension to the master communications device providing a larger interface to the operator.

## Background
BACKGROUND
1. Field of Invention
The invention relates to communications devices, and more specifically to intelligently operating multiple communications devices within an interactive communications system environment.
2. Related Art
Typically, a communications system includes a single device that allows an operator to operate and/or control the communications system. For example, the operator when interacting with the communications system is limited to the features and resources available to the operator by the device.
Operation of the communications system in the manner described above limits the operator to the size and the capabilities of the conventional device when interacting with the communications system. The typical device may be adequate for the operator when performing certain tasks with the communications system such as placing a telephone call. However, the operator may also wish to operate the communications system for other tasks that require additional features and resources that the device cannot provide such as simultaneously browsing the internet and/or reading emails. The operator of the communications system will be limited to the conventional device and cannot add to the features and resources of the conventional device, such as increase the size of the display for the conventional device to provide an example, in operating the communications system.
Thus, there is a need to add additional features and resources to the conventional device when required by the operator while allowing the operator to return to the conventional device when the operator no longer requires additional features and resources. Further aspects and advantages of the invention will become apparent from the detailed description that follows.

A First Exemplary Master Communications Device/Slave Device Configuration
FIG. 2 illustrates a block diagram of a master slave communications system 200 according to an exemplary embodiment of the invention. A master communications device 202 may be integrated with a slave device 204 to form the master slave communications system 200, where the slave device 204 may be representative of a plurality of slave devices 204.
The master communications device 202 may be, for example, a mobile telephone, a portable computing device, other computing devices such as a personal computer, a laptop, or a desktop computer, a computer peripheral such as a printer, a portable audio and/or a video player, a payment system, a ticketing writing system such as a parking ticketing system, a bus ticketing system, a train ticketing system or an entrance ticketing system to provide some examples, or in a ticket reading system, a toy, a game, a poster, packaging, an advertising material, a product inventory checking system and/or any other suitable electronic device that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention.
The master communications device 202 may also include a touch-screen display, an alphanumeric keypad, a microphone, a mouse, a speaker, a liquid crystal display (LCD), a light emitting diode (LED), a projector, a plasma television, data light processing (DLP) projector, liquid crystal on silicon (LCoS), digital direct drive image light amplifier (D-ILA), cathode ray tube (CRT), and/or any other suitable user interface that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, or any combination thereof.
The slave device 204 may include a touch-screen display, an alphanumeric keypad, a microphone, a mouse, a speaker, and/or a liquid crystal display (LCD), a light emitting diode (LED), a projector, a plasma television, data light processing (DLP) projector, liquid crystal on silicon (LCoS), digital direct drive image light amplifier (D-ILA), cathode ray tube (CRT) and/or any other suitable device that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, or any combination thereof.
The master slave communications system 200 enables the seamless and automated attachment of the slave device 204 to the master communications device 202. The operator may require additional functions and resources that the master communications device 202 alone cannot provide. In such a case, the master communications device 202 may in a seamless and automated fashion engage the slave device 204 where the slave device 204 and the master communications device 202 provide an interactive communications system to the operator.
For example, the operator may enter a conference room with a master communications device 202 that is a personal laptop. The operator may require a larger display to properly display the information currently displayed on the master communications device 202. The master communications device 202 may engage the slave device 204 that is a projector located in the conference room to display the information of the master communications device 202 on the wall of the conference room. Such an interaction between the master communications device 202 and the slave device 204 may be seamless and automated.
When requested to perform a particular service by the operator, the master communications device 202 takes an inventory of the features and resources that are necessary for providing the particular service, and compares the inventory to those resources contained solely in the master communications device 202. If the features and resources contained in the master communications device 202 are sufficient to perform the service for the operator, then the master communications device 202 performs the service. However, if the features and resources of the master communications device 202 are not be sufficient to perform the service for the operator, then the master communications device 202 may engage the slave device 204 to provide additional features and resources that are necessary or desired to perform the service.
The master communications device 202 may operate in a discovery mode and the slave device 204 may operate in an advertise mode. The master communications device 202 enters into discovery mode to search for slave devices, such as the slave device 204, to expand the features and resources of the master communications device 202 to include the features and resources of the slave device 204. The slave device 204 enters into advertise mode to notify the master communications device 202 that the slave device 204 is ready to engage with the master communications device 202. Either the master communications device 202 and/or the slave device 204 may initiate the engagement between the devices. The operator may also set both the master communications device 202 and the slave device 204 into the discovery and advertise modes, respectively. In an embodiment, the master communications device 202 has no inherent resources of its own, and therefore is always operating in discovery mode once a service request is received. Likewise in a further embodiment, the slave device 204 is always in an advertise mode; such a slave device may be a conference projector, for example.
In an embodiment, the master communications device 202 and the slave device 204 may engage with each other in the discovery and/or advertisement modes using a sensor, as discussed in greater detail below. As would be appreciated those skilled in the relevant art(s) without departing from the spirit and scope of the present invention, a sensor receives a signal and responds to the received signal. The sensor may be located on the master communications device 202 and/or the slave device 204. As an example, the sensor may be a near field communications device (NFC) or other wireless device to effect the sensor operations.
As discussed above, the operator in operating the master communications device 202 may require additional features and resources over and above those contained in the master communications device 202. In response to the operator's requirements for additional features and resources, the master communications device 202 may enter discovery mode and sends out a slave device request signal 272 to one or more slave devices 204. In response, the slave device 204 sends a slave device discovered signal 276 that indicates whether the slave device 204 is available to the operator. The master communications device 202 receives the slave device discovered signal 276 when the master communications device 202 is able to detect the slave device 204. The master communications device 202 may detect the slave device 204 when the slave device 204 comes within the detection range of the master communications device 202.
The master communications device 202 may also detect a slave device 204 that is operating in an advertise mode. In advertise mode, the slave device 204 generates a slave device advertiser signal 274 that indicates the availability of the slave device 204 to the master communications device 202. In some embodiments, the slave device 204 not only advertises it availability, but also its various capabilities to the master communications device 202. In a further example, the master communications device 202 may instruct the slave device 204 to enter advertise mode using either of signals 274 or 276, so that the master communications device 202 can select an appropriate slave device to meet particular operator requirements.
The master communications device 202 may receive an operator request input 270 that defines requirements for selecting one or more slave devices 204. For example, operator request 270 may define requirements for a slave device to perform a particular function or service, and/or define the number of slave devices that will be necessary to perform a particular service.
Using the slave device request signal 272, the master communications device 202 may also query the resources or capabilities of the slave device 204. The resources of the slave device 204 may include resources that may be provided to the operator. Resources of the slave device 204 may include but not limited to display dimensions, bit per pixel, aspect ratio, frame rate, audio channels, and/or the audio sampling rate.
As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, embodiments of the master slave communications system 200 may include any quantity of slave devices 204 in addition to the master communications device 202. Further, the master slave communications system 200 may include any quantity of master communications devices 202 in addition to the slave device 204.
A Second Exemplary Master Communications Device/Slave Device Configuration
FIG. 3 illustrates a block diagram of a second master slave communications system 300 according to an exemplary embodiment of the invention. The master communications device 202 may be integrated with the slave device 204 to form the master slave communications system 300. The master communications device 202 includes a memory 318 and a master/slave device controller 306.
The master communications device 202 provides functions which may include wireless communication, computing capabilities, and/or any other suitable functionality that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the present invention. The master communications device 202 may also support services relating to computing capabilities, such as Short Message Service (SMS), electronic mail, Internet access, gaming, short range wireless communications, camera, Multimedia Messaging Service (MMS) messaging, digital audio player, radio, and Global Positioning System (GPS) services and/or any other suitable service that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the present invention.
As shown in FIG. 3, the master/slave device controller 306 may receive a received communications signal 360 from another communications device. The master/slave device controller 306 downconverts, demodulates, and/or decodes the received communications signal 360 to recover information, such as one or more commands to be executed by the master communications device 202 and/or data to provide some examples, that is embedded within the received communications signal 360.
As another example, the master/slave device controller 306 may provide a transmitted communications signal 362 to another communications device. The master/slave device controller 306 upconverts, modulates, and/or encodes information to provide the transmitted communications signal 362, where exemplary information may include one or more commands that are to be executed by another communications device and/or data to provide some examples. As a further example, the master/slave device controller 306 may receive the received communications signal 360 from a first external communications device and provide the transmitted communications signal 362 to the same first external communications device, or to a second external communications device.
The master/slave device controller 306 also processes the received communications signal 360 to properly route the information, such as one or more commands and/or data, embedded within the received communications signal 360 to the slave device 204 as slave device data 356. Further, the master/slave device controller 306 may save the received communications signal 360, or a processed version thereof, in the memory 318 as communications data 370.
For example, the master/slave device controller 306 may format the received communications signal 360 into data frames and may perform error encoding, such as cyclic redundancy check (CRC) to provide an example, on the data frames prior to forwarding as slave device data 356 or communications data 370. The data frames may include frame delimiters to indicate a start and/or an end of each of the data frames. As a further example, the master/slave device controller 306 may parse the received communications signal 360 prior to generating the slave device data 356 and/or the communications data 370. The received communications signal 360 may include a header of one or more bits as part of the information. The one or more bits of the header may be interpreted by the master/slave device controller 306 to deter nine whether to route the received communications signal 360 to the slave device 204 and/or to the memory 318. Further, the master/slave device controller 306 may receive and format slave device data 356, for transmission as transmitted communication signal 362. Likewise, master/slave device controller 306 may retrieve and format the communications data 370 for transmission, as transmitted communication signal 362.
The memory 318 reads and/or writes the communications data 370. The memory 318 may include a data store such as a transponder, a tag, a smartcard, read only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices and/or any other suitable machine-readable medium that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention that is communicatively coupled to the master/slave device controller 306.
The master/slave device controller 306 processes the operator request input 270, the slave device discovered signal 276, and the slave device advertiser 274 and determines the slave devices, such as the slave device 204 that may be available to the operator through the master communications device 202. In some embodiments, the operator requires added capabilities that the master communications device 202 cannot provide alone. For example, but without limitation, a larger display may be needed to properly view information of received communications signal 360. The master/slave device controller 306 may route at least a portion of the information that is embedded within the received communications signal 360 to the slave device 204 as the slave device data 356. In this example, the complement of services that is provided to the operator is split between the master communications device 202 and the slave device 204. In such a case, the slave device 204 serves as an extension to the master communications device 202 so that the slave device 204 and the master communications device 202 serve the operator as a single interactive system.
When operating as an output device, the slave device 204 receives the slave device data 356 from the master/slave device controller 306, and operates as an output device for the master slave communications system 200. For example, the slave device data 356 may represent data to be displayed by the slave device 204 and/or one or more commands to be executed by the slave device 204.
Alternatively, the slave device 204 may operate as an input device to receive information from the operator that is to be provided to the master/slave device controller 306 as the slave device data 356. The information from the operator may represent data from the operator and/or one or more commands to be executed by the master slave communications system 300.
The master/slave device controller 306 also monitors an available slave device resources signal 352 to determine the resources of the slave device 204 required and/or available to execute the requests of the operator. The slave device resource signal 352 identifies the available resources for one or more slave devices 204. In an embodiment, the master/slave device controller 306 queries the slave device 204 to determine the resources available to the operator in the slave device 204, in order to execute the requests of the operator. Resources requested by the master/slave device controller 306 may include but are not limited to: audio channel, display area, specific frame rate, and specific aspect ratio. If the desired requirements are met, then the slave device 204 grants the requested resources to the master/slave device controller 306.
The following example illustrates the engagement between the master communications device 202 and the slave device 204, where the example is illustrated in the context of visual displays and resources associated with visual displays. As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, the visual displays may also have audio and touch screen capabilities without departing from the spirit and scope of the present invention. The following example applies to any type of resource related to: audio, video, visual, touch screen, and/or any other type of implementation without departing from the spirit and scope of the present invention.
For example, the master/slave device controller 306 queries the slave device(s) 204 to determine the respective available resources, and in response receives the available slave device resources signal 352. The master/slave device controller 306 determines that the frame rate of the slave device 204 is 30 frames per second, the aspect ratio is 4:3, and the bit per pixel is 4:4:4, by examining the available slave device resources signal 352. The master/slave device controller 306 then requests the same frame rate, the aspect ratio and the bit per pixel resources from the slave device 204. The slave device 204 grants the frame rate, the aspect ratio, and the bit per pixel resources to the master/slave device controller 306.
The master/slave device controller 306 processes the available slave device resources signal 352 to intelligently route the slave device data 356 to the slave device 204. For example, the master/slave device controller 306 receives the available slave device resources signal 352 that identifies the frame rate of 30 frames per second, the aspect ratio of 4:3, and the bit per pixel of 4:4:4 for the slave device 204. As another example, the available slave device resources signal 352 may identify exemplary display screen parameters of the slave device, such as 1680×1050 for a screen size. Based on these resources, the master/slave device controller 306 configures the master communications device 202 and the slave device 204 in order to best display information to the operator, where the configuration takes into account the resources of the slave device 204. The master/slave device controller 306 communicates the configuration of the slave device 204 with the slave device data 356.
For example, the master/slave device controller 306 sets the proper audio sampling rate, the proper bit rate, the proper display configuration, and the proper ratio for the master communications device 202 and the slave device 204 so as to properly display the information to the operator. For example, the master communications device 202 may include a high definition television (HDTV) with a bit rate of 15 Mbit/s. However, the available slave device resources signal 352 may include a standard definition television bit rate of 3.5 Mbit/s. Based on the bit rate of the slave device 204, master/slave device controller 306 may configure the display of the master communications device 202 to occur at the slave device 204 bit rate of 3.5 Mbit/s rather than the master communications device 202 bit rate of 15 Mbit/s. In doing so, the information may be properly displayed to the operator on the master communications device 202 and the slave device 204. The master/slave device controller 306 communicates the bit rate of 3.5 Mbit/s to the slave device 204 with the slave device data 356.
In another example, the master/slave device controller 306 configures the master communications device 202 and the slave device 204 so that the master communications device 202 and the slave device 204 display the information as a single display to the operator. In such an example, the master/slave device controller 306 may configure the master communications device 202 to display half of the information (e.g. half of an image). The master/slave device controller 306 may also configure the slave device 204 to display the other half of the information. In doing so, the master communications device 202 and the slave device 204 act as a single interactive system to the operator in displaying the information. The master/slave device controller 306 communicates the portion of the information to be displayed by the slave device 204 with the slave device data 356.
As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, any combination of the information may be displayed on any combination of the master communications device 202 and the slave device 204. Further, any quantity of master communications devices and slave devices may be incorporated without departing from the spirit and scope of the invention. For example, the master/slave device controller 306 may configure the master communications device 202 and multiple slave devices 204 so that each displays fractional portions of the information, where the fractional portions assigned to the various devices may be different from each other.
Exemplary Embodiments of Master Communications Device/Slave Device Configurations
The following exemplary embodiments illustrate the engagement between the master communications device 202 and the slave device 204. The below example is illustrated in the context of visual displays and resources associated with visual displays. As would be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the invention, the visual displays may also have audio, touch screen sensing capabilities, and/or any other capabilities without departing from the spirit and scope of the present invention. The following examples apply to any type of resource related to audio, video, visual, touch screen, and/or any other type of implementation without departing from the spirit and scope of the present invention.
FIG. 4A illustrates a first exemplary master communications system according to an exemplary embodiment of this invention. The master communications system 400 includes the master communications device 202, a master display 402, a sensor 408, and display information 404.
The master display 402 may be, for example, an output device to display information to the operator relating to the services provided by the master communications device 202. Specifically, the master display 402 may be configured to display all of the data included in the display information 404. The master communications device 202 communicates the display information 404 to the master display 402 using the master display data 458. In such an example, additional devices are not required by the operator.
FIG. 4B illustrates a first exemplary master slave communications system 420 according to an exemplary embodiment of the invention. The master slave communications system 420 includes the master communications system 400, a slave device 204, and a sensor 430. The master communications system 400 includes the master communications device 202, the master display 402, and the sensor 408. The slave device 204 and the master display 402 each display portions of the display information 404.
The slave device 204 may be, for example, an output device to display information relating to the services provided by the slave device 204 to the operator. Specifically, the slave device 204 may be configured to display a portion of the data included in the display information 404. Accordingly, the slave device 204 may be configured to display the portion of the data included in the display information 404 that is not displayed by the master display 402. The master communications device 202 communicates the portion of the display information 404 to be displayed by the master display 402 using the master display data 458. The master communications device 202 communicates the portion of the display information 404 to be displayed by the slave device 204 using the slave device data 356.
The master display 402 may be extended by attaching the slave device 204 to the master display 402. By attaching the slave device 204 to the master display 402, the display provided to the operator is enlarged. Instead of attachment, the slave device 204 may simply be placed physically adjacent to the master display 402, as shown.
