The telephone 102 can also work with a radio frequency signal line 316 in the form of the coaxial connector 118 be provided.
As described above, the shot is 104 with an electrical connection part 124 for electrically connecting the receptacle 104 with the phone 102 Mistake. Some of the through the connection part 124 Arriving electrical signals are easily absorbed by the recording 104 to the electrical connection part 136 directed and thereby directly to the interface module 106 guided. Other signals are manipulated or processed within the recording 104 , For example, the analog audio output signal becomes 304 via an analog audio amplifier 318 in the recording 104 strengthened. In addition, a microprocessor processes 320 Telephone control signals on the telephone control signal bus 314 that between the phone 102 and the recording 104 pass through and communication signals) on the receiving IM bus 322 , performed between the recording 104 and the interface module 106 , The recording memory 324 can with the microprocessor 320 be associated. The recording memory 324 may be an addressable memory space, such as a ROM, RAM, EEPROM, flash memory, or a combination of memory types. All or part of the memory 324 can from the recording 104 be removable. The recording 104 also includes a basic signal 326 to the interface module 106 over the electrical connection parts 134 and 136 the presence or absence of admission 104 to signal.
The interface module 106 includes processing hardware and software, including at least one microprocessor and / or processor 328 for digital signals, a programmable power supply 330. , a DC-DC converter 332 , a Near-End Encoder / Decoder (CODEC) 334 , a far-end CODEC 336 , one or more universal asynchronous receiver / transmitter 338 (UART) and an IM memory 340 , The IM store 340 can be any addressable memory space such as a ROM, RAM, EEPROM, flash memory or a combination of memory types. All or part of the memory 340 can from the interface module 106 be solvable. The interface module 106 also includes a multiplexer 342 , an analog audio (-signal) amplifier 344 and earth conductors 326 and 346 to create a common ground between recording 104 and the interface module 106 to set up.
The interface module 106 can additionally an interface 348 to the interface module 106 with different external subsystems or subsystems 378 connect to. The interface 348 can comfortably on a daughter board 380 be mounted to the performance of the interface module 106 easy to expand. The daughterboard may also have a microprocessor that has server capabilities. Instead of such a daughter board 380 , all their capabilities and the interface module components and their functionalities can be integrated on a single chip. In general, it allows the provision of the interface 348 the interface module 106 , as a communication center for various external subsystems 378 to serve. These external subsystems 378 may include personal computers, auto-PCs, Global Positioning System (GPS) units, Personal Digital Assistants (PDA); Devices for storing digital audio signals for playing on the car stereo, such as devices for storing music in MP3 format; Data network or the communication bus of the vehicles, such as a Controller Area Network (CAN), other data networks or communication buses, visual displays; Devices using a Bluetooth communication protocol or other communication protocols; or other electronic systems. In connection with the possible implementation of the Bluetooth technology, such in the interface module 106 be integrated, as well as in the recording 104 includes his. In such a case, the Bluetooth technology does not have to be part of the wireless phone 102 or other wireless communication device. According to this embodiment, the recording 104 and the interface module 106 cooperate to provide services to associated Bluetooth devices. In this embodiment, the number of signal-conducting wires is substantially reduced. However, one or more wires may be required or suitable for providing charging functions and / or an external antenna port.
In terms of facilitating communication with the vehicle that the wireless communication device 102 , in particular communication with vehicle subsystems 378 who use the internet can have the vehicle subsystems 378 be configured so that they are separately accessible. These individualized communications are preferably not achieved by having separate Internet Protocol (IP) addresses for each of the vehicle subsystems 378 but by including an address-related mapping technique. In accordance with the preferred embodiment, the particular vehicle has only one IP address or at least the number of IP addresses associated with the vehicle and vehicle subsystems is less than the total number of vehicle subsystems. In the case where the vehicle has only an IP address, it is necessary to route the received communication to the desired vehicle subsystem. This can be accomplished by associating or correlating ports or other identifiers to each of the vehicle subsystems that are interested in facilitating such communication. Will be a communication for a particular vehicle subsystem 378 receive, this is how the interface module works 106 and / or the associated daughter board 380 such that it detects the content of the received communication at the port or other identifier associated with a particular vehicle subsystem 378 depict what the recipient of this communication should be. In a preferred embodiment, where it is desirable to communicate with multiple or fleet of vehicles from a common off-vehicle location, each vehicle of the fleet would be assigned a separate IP address. However, the identifiers or ports associated with each of the vehicle subsystems in that fleet would have the same or a corresponding port or other identifier. For example, the vehicle subsystem 1 in the vehicle 1 would have the same port number or other identifier as the vehicle subsystem 1 in vehicle 2, although the IP addresses of the vehicle 1 and the vehicle 2 would be different. This embodiment is very advantageous in managing vehicle fleets, particularly in transmitting / receiving information regarding each of a plurality of vehicle subsystems in a large number of vehicles. In this regard, such an embodiment makes it easier to identify and locate each of the vehicle subsystems in a fleet since the same vehicle subsystem 378 in a vehicle has the same identifier as an identical vehicle subsystem in another vehicle in the fleet.
With respect to sending a first communication to a first vehicle subsystem located in a first vehicle, communication may be prepared at a location remote from the vehicle. The communication package includes an IP address for the first vehicle. The communication packet also includes address-related (eg, port) information or other identifying information associated with the first vehicle subsystem to receive that first communication packet. The first communication packet is sent over the Internet to the first vehicle and has the IP address in the communication packet. This communication packet is then from the wireless telephone or other wireless communication device 102 receive. Subsequently, a determination is made with respect to the last location or vehicle subsystem receiver of the first communication packet. This determination may be made by processing hardware and software in the interface module 106 and / or other processing hardware / software, possibly including a server on the daughterboard 380 , As part of the processing or determination operations, mapping or other correlation may be provided between the information in the first communication packet related to identifying the particular vehicle subsystem that is to receive the communication packet and a port or other identifier associated with that vehicle subsystem. After completing the mapping, the communication packet may be routed to the particular first vehicle subsystem that was designated as the recipient of that communication. As can be seen, in the case where the same communication is to be sent to the same vehicle subsystem located in several vehicles of a fleet, only the IP address for each vehicle needs to be changed to its dedicated vehicle IP address. As will be further appreciated and when it is desirable to send communication to a second vehicle subsystem located in the first vehicle, simultaneously or at different times, the same IP address may be used in conjunction with that first vehicle while the mapping function with which it is to be made possible that the communication with the second vehicle subsystem can be received, is manageable within the vehicle.
In Similarly, when communicating from the vehicle to a Place outside of the vehicle, such as a common location with sending / receiving communications to / from a fleet of vehicles, and that the transmission data or other information from one or more vehicle subsystems in the vehicle comprises also the Network Address Translation (NAT) be accomplished. In particular, leads the server or other processing hardware / software performs an address translation through, over which the vehicle IP address is delivered before communicating over the Internet is sent.

As mentioned above, the phone can 102 generally used for transmitting and receiving voice and data signals over an air connection to a base station, such as a radio cell in a mobile telephone system. In addition, the phone allows 102 typically storing indexed lists of telephone numbers to provide the user with a customized list or directory of telephone numbers. Also, the phone is 102 with a speaker 108 and a microphone 110 provided to allow the user to make calls over the phone 102 to lead when the phone 102 is held against the face of the user. A keyboard 102 is typically used to enter numbers and initiate dialing, answer incoming calls, and enter information regarding the telephone listing. A visual ad 114 is typically intended to display the number to be called, memory entries or other information. The telephone 104 can have a battery 107 be energized so that the phone 102 is easy to carry.
The telephone 102 however, it is typically not equipped with features that allow for easy hands-free use in an automobile. For example, to take a call, it is typically necessary for the user to dial the number using the keyboard 112 to enter or again the keyboard 112 to select from an entry from a user-defined listing. The use of the keyboard requires that the user turn his or her eyes away from the road to the keyboard 112 and the ad 114 to look at and a hand off the steering wheel of the automobile 302 to enter the number or select the desired option. Of course, this is disadvantageous if the user uses the automobile 302 moves. Although a few phones 102 are available with built-in speech recognition features, they are systems for "near-talking" and not well suited for use in vehicles or other environments where "remote speech" occurs. Therefore, it is desirable to provide a system that provides reliable, hands-free operation of the phone 102 allowed.
As can be seen, the phone can 102 come from any of a variety of manufacturers, each of which can produce a variety of different models. Accordingly, the physical shape of the phone 102 as well as the physical design of the electrical connector 116 and the special signal lines that go through the electrical connector 116 be provided, very different. It is also subject to the phone 102 recognized communication protocol generally in its capacity of making the phone 102 and can be part of phone models 102 which are manufactured by a single manufacturer differ.
To the physical, electrical and communication protocol differences among phones 102 in their multiplicity, the present invention contemplates several different configurations of receptacles 104 in front. Therefore, a recording 104 be provided with the most diverse physical configurations of different phones 102 matches. Accordingly, the recess 120 and the surface features 122 generally determined by the physical characteristics of the phone 102 which is intended by the special recording 104 to be included. In addition, the electrical connection part 124 physically configured such that it with the electrical connector 116 on the phone 102 matches. Where the phone 102 a coaxial connector part 118 for a radio frequency signal line, the recording 104 a matching coaxial connector 126 provide. This way a special phone can be used 102 mechanically with the appropriate receptacle 104 match.
As mentioned above, the special, from the phone 102 provided electrical signal lines and that of the phone 102 used communication protocol vary from manufacturer to manufacturer and even between different models of telephones 102 made by a special manufacturer. Therefore, the phone 102 with the recording 104 and the interface module 106 and again with the automobile 302 Arrangements must be made to meet these differences. Accordingly, the recording 104 be designed so that they are the specially designed and kind of electrical signal lines, over the phone 102 be provided. In a physical sense, this is accomplished by connecting the designated signal lines (e.g. 304 . 306 . 308 . 310 . 312 . 314 . 303 and 316 ) with corresponding contacts, if provided, in the electrical connection part 116 and 118 of the phone 102 ,
In addition, the recording 104 with a microprocessor 320 and associated recording memory 324 provided for coupling with the supplied telephone control signals 314 of the phone 102 , In this way, the electrical and communication protocols of the phone 102 from the special recording 104 which is designed for use with the special telephone 102 , In particular, the memory 324 the recording 104 includes a code that allows the recording 104 a conversion takes place between commands contained in the API of the system 100 are formatted and the communication interface of the phone 102 , Although the recording 102 is designed physically and electrically for use with special phones, it is desirable that the interface module 102 with each of the scheduled shots 104 and the associated phones 102 can be operated. The provision of a common interface module 106 Can the cost of the system 100 reduce, because only the recording 104 must be changed to the widely different phones available in the market 102 take. To further increase the benefits obtained by using a common interface module 106 , are many of the components or components that are necessary to the functions of the system 100 in the interface module 106 arranged. Conversely, the number of and the cost of the components required for the recording 104 are required to achieve the desired functions, minimized. Although the interface module 106 Moreover, all of these functions may not be available to a user who is recording 104 which allows access to only a limited number of potentially available functions. Also, those of a special shot 104 Supported or provided functions are changed according to the operationally available functions when using the special phone 102 or according to the functions of the special recording 104 get supported.
Referring now to 6 , there are several shots 104a . 104b . 104c . 104d . 104e . 104f . 104g and 104h each of which has different physical and / or functional compatibilities, but they are all physically and functionally compatible to a common interface module 106 are. The pictures A1 104a , A2 104b , A3 104c and A4 104d For example, they may be compatible with the physical characteristics of the phones A1 102 , A2 102b and A3 102c which are manufactured by a single manufacturer A. The recordings B1 104e , B2 104f , B3 104g and B4 104h can be physically compatible with the phones B1 102d , B2 102e , B3 102f and B4 102g manufactured by the manufacturer B or alternatively manufactured by the manufacturer A, but different physical characteristics from the telephones 102 . 102b and 102c to have. Although in the example the recordings 104a -d bodily to the phones 102 -c are compatible and the shots 104e -h physically compatible with the phones 102d -g, all the different features of the phones can be 102 -c not all of the shots 104a -d be supported or held and all the different features of the phones 102d -g can not do all of the shots 104e -h are supported. Similarly, the functional or other capabilities of the recordings 104a -h not all of the phones 102 -g be supported. In 6 All the functional compatibilities between the individual recordings become 104a -h and the individual phones 102 -g represented by arrows. A full arrow from a pickup 104 to a telephone 102 indicates that all the features of the special phone 102 from the special recording 104 be sustained while solid arrows from a telephone 102 to a recording 104 state that all the skills of the special recording 104 through the special phone 102 be supported. A dashed line from a telephone 102 to a recording 104 indicates that only one subset or subset of the recording capabilities 104 from the special phone 102 be supported while a dashed line from a recording 104 to a telephone 102 indicates that only a subset of the capabilities of the particular phone 102 from the special recording 104 is supported.
As an example, the phones A1 102 , A2 102b and A3 102c share common physical attributes and allow any of these phones to mechanically record with each of the recordings A1 104a , A2 104b , A3 104c and A4 104d connected to who the.
The phones A1 102 , A2 102b and A3 102c however, they can have different functional abilities. Similarly, the shots A1 104a , A2 104b , A3 104c and A4 104d support different functions. For example, the pictures A1 104a , A2 104b and A3 104c all the functional capabilities of the phones A1 102 and A2 102b support, but only a subset or a subset of the capabilities of the phone A3 102c while recording A4 104d all the functional capabilities of the phones A1 102 , A2 102b and A3 102c can support. The phones A1 102 and A2 102b can all the functional abilities of the recordings A1 104a , A2 104b and A3 104c but only a subset of the functional capabilities of the A4 recording 104d while the phone is A3 102c all the functional abilities of the A1 shots 104a , A2 104b , A3 104c and A4 104d can support. Examples of the interaction between the recordings 104 with different functional abilities and phones 102 with different functional capabilities will now be explained in connection with various examples.
The recording A1 104a can be a level one shot that is just the most basic of the system 100 supported functions (below). Therefore, the recording A1 104a provide basic speaker phone functions when connecting the phones A1 102 , A2 102b or A3 102c with the interface module 106 , The basic speaker phone features may include providing a speaker 366 and a microphone 368 include allowing the user to conduct a conversation via a wireless connection to the telephone 102 is made without the phone 102 must be held on her or his face. Therefore, referring now to FIG 3 , the recording A1 104a Analog audio signal lines 304 and 306 Provide analog audio signals to and from the phone 102 to deliver, using the phone, for example, phone A1 102 , an analog audio input and output provides. The recording A1 104a can also analog audio signal amplifier 318 and 502 (please refer 5 ) to allow adjustment of the gain of the analog audio signals. The recording A1 104a then sees connections for the analog audio signals with the interface module 106 in front. Where the phone A1 102 provides a digital input or output, such as the telephone A2 102b , lead the digital audio signal lines 308 the recording A1 104a the digital audio signal directly to the interface module 106 , In general, the capabilities and characteristics of the phone 102 the interface module 106 from the recording 104 communicates via the receiving IM communication bus when the recording 104 initially on the interface module 106 is connected.
The recording A1 104a can also be a power supply or power supply line 303 Provide for charging the battery 107 of the phone 102 and / or providing a power to operate the phone 102 , The recording A1 104a also includes telephone control signal lines 314 between the phone 102 and the microprocessor 320 , Finally, the recording A1 104a a radio frequency signal line 316 provide, wherein a connection part 118 for radio frequency output from the phone 102 is provided.
According to the embodiment of the system 100 with a level one recording A1 104a , the phone will 102 physically in place in the automobile 302 and is equipped with a speaker / phone functionality. Therefore, if a phone call from a remote location on the phone 102 In general, the user must have a button on the keyboard 112 of the phone 102 Press to establish communication with the phone at the remote location. This setup of communication link with the remote location becomes the recording 104 through the phone 102 over the telephone control signal lines 314 signaled. The shape of the phone 102 emitted signals is generally peculiar to the manufacturer of the phone 102 , Accordingly, it may consist of a serial digital message or simply by changing the voltage on an electrical contact on the telephone 102 , The recording 104 and in particular the microprocessor 320 are programmed to be the special, from the phone 102 Detect a sent message to indicate that a call comes in. The microprocessor 320 then convert the message from the phone 102 into one that conforms to the application programming interface (API) of the system 100 , This message can then be sent from a serial I / O port to the microprocessor 320 over the receiving IM communication bus 322 to the far-end UART 338 and from there to a parallel input / output port connected to the interface module microprocessor 328 of the interface module 106 is provided. The interface module microprocessor 328 then checks the message regarding the incoming call from the phone 102 comes from and into the API of the system 100 has been implemented and generally configures the system 100 such that it is ready to handle the call. In particular, the interface module microprocessor activates 328 the shutdown signal line 362 to any output signal from the audio system 373 of the automobile 302 switch off or mute. If the phone has an analog audio input signal 306 and an analog audio output 304 provides, the interface module microprocessor 328 also the amplifier 318 for the analog audio output signal. If therefore the phone 102 provides an analog audio signal, therefore, the signal from the amplifier 318 amplified for analog audio signals and to the interface module 106 where the analog signal is digitized from the far-end CODEC 336 , The now digital audio signal is then sent to the multiplexer 342 passed on and on to the interface module microprocessor 328 with a serial I / O port. The interface module microprocessor 328 can then perform a variety of signal processing functions with respect to the audio signal. These functions may include cancellation of reverberation, cancellation of line echo, noise suppression and frequency adjustment. The digital signal processor can also perform partial full-duplex operation and automatic volume control functions. The processed digital audio signal is then forwarded from a serial I / O port of the interface module microprocessor 328 to the near-end CODEC 334 where the digital audio signal is converted back to an analog signal. The analog signal can then be in the amplifier 344 for analog audio signals at the line level, amplified and conditioned before being transmitted by the audio system 373 is amplified or via a power amplifier in connection with the speaker 366 and from the speaker 366 be issued.
Speech signals from the user in the automobile 302 be at the microphone 368 which can have built-in noise reduction capabilities and digitized by the near-end CODEC 344 before being forwarded to the serial I / O port of the interface module microprocessor 328 , Again, a variety of signal processing functions in the interface module microprocessor 328 be performed before the digital audio signal to the multiplexer 342 and continue to the far-end CODEC 336 is directed. The far-end CODEC 336 converts the digital audio signal into an analog signal sent to the phone 102 is forwarded so that it can be sent over the air connection to the remote location.
Where the phone is 102 digital audio inputs and outputs, such as the phones A2 102b and A3 102c , signals are sent through the system 100 in general as described above, except that the digital audio signals between the phone 102 and the interface module microprocessor 328 over the multiplexer 342 with no intervening gain and without passing through the far-end CODEC 336 reach.
Stage one recording A1 104a can also use the phone 102 with power or energy to charge the battery 107 and to operate the phone 102 via the power supply line 303 Mistake. In general, the microprocessor 320 the recording 104 programmed to supply the appropriate voltage or current from the programmable power supply 330. of the interface module 106 requests. Of course, the power requirements of the phone can 102 according to the operating state of the telephone 102 or the charge of the battery 107 to change. Therefore, the phone can 102 For example, request that power be supplied at a first voltage when the phone 102 is in a dormant state and with a second voltage when the phone 102 is in an active state. The different voltages requesting signal can from the phone 102 over the telephone control signal lines 314 to the microprocessor 320 where the request is implemented at the system's API 100 , The interface module microprocessor 328 then can the programmable power supply 330. so steer that it supplies the requested energy. The receptacle may also include a current limiter or voltage regulator as required.
Because the recording 104 is configured to provide a predetermined set of functionalities and with a predetermined telephone or set of telephones 102 will probably be used, the microprocessor 320 and in particular the memory 324 in the context of the microprocessor 320 be programmed to use the special signals of the phone 102 translate into commands that are in the system API 100 are included. In addition, the recording 104 with the power requirements of the phone 102 be programmed. This information in relation to that from the phone 102 Supported functions and requests can be made via the receiving IM communication bus 322 the interface module microprocessor 328 be communicated or communicated when recording 104 into the interface module 106 is plugged in. The recording 104 also communicates information relating to the recording 104 supported functions to the interface module 106 , In general, the interface module 106 activated when recording 104 into the interface module 106 is plugged in and the recording detection mass 326 between the recording 104 and the interface module 106 is set up.
A second shot 104b , which is known as level two recording, can provide additional functionality. For example, the recording 104b support audible prompts, voice commands and a record of voice memoranda. As in 6 shown who the functionalities of the recording A2 104b completely from the phones A1 102 , A2 102b and A3 102c even if it provides these additional functionalities. Also, the interface module 106 be identical to the one with regard to the photograph A1 104a has been described. Regarding the basic telephone speaker functions provided by the system 100 in connection with the recording A2 104b are provided, the functions and connections are in accordance with, as described above with respect to the recording A1 104a has been described.
To support voice commands, the recording A2 104b be programmed to send appropriate messages between the phone 102b and the interface module 106 promoted. For example, the recording A2 104b be capable of the phone 102 with a phone control signal indicating the phone 102 asks to accept an incoming call. This is in contrast to the one above with regard to the photograph A1 104b provided example in which the user has a button on the keyboard 112 of the phone 102 to answer an incoming call. In addition, the microprocessor must 320 the recording 104b API commands for functions such as answering an incoming call. Besides the possibility of additional functionalities such as speech recognition and the recording of voice memoranda, however, the recording is A2 104b according to an embodiment of the present invention, the same as the receptacle A1 104a ,
Audible voice prompts become, according to an embodiment of the system 100 According to the present invention, provided to the system 100 operating user. Audible prompts are particularly advantageous when used in conjunction with speech recognition functions as they affect the operation of the system 100 simplify, without requiring the user his view of the system 100 must throw itself. For example, the system can 100 recognize commands issued by the user or inform the user of the status of the system 100 supply. The audible prompts may be in the recording memory 324 and / or the IM memory 340 previously recorded and saved with or without compression. Alternatively or additionally, the audible prompts of text generated in the memory may be generated 324 and 340 is saved, taking advantage of text-to-speech functionality (described below). According to one embodiment, the voice prompts are stored in an easy-to-change memory 324 or cassettes 340 saved, so that the existing system 100 upgraded or upgraded or to include a different or additional language.
The interface module 106 can include speech recognition capabilities to the system 100 to enable voice commands to be recognized. This in connection with the recording A2 104b used interface module 106 can be identical to that in connection with the recording A1 104a used interface module 106 be. Alternatively, with the recording A2 104b used interface module 106 be improved to provide speech recognition capabilities. Even if the interface module 106 is provided in different models that provide different capabilities, so is any interface module 106 preferably at least partially compatible with any recording 104 , In general, language models will be in the IM memory 340 or the recording memory 324 saved to the system 100 to enable detection of universal commands such as "answer call" or "make call". There may be different memory 224 or cassettes 340 be provided to easily upgrade the language models or change them into different languages. In addition, precautions in the interface module 106 are taken to store user-defined commands, such as "call home" or "call Mary". According to an embodiment of the present invention, the user-defined commands and voice memoranda may be in the removable memory 324 and 340 saved to their use in other systems 100 or in compatible devices, for archiving memoranda, or to facilitate the use of different instruction sets.
The removable storage 324 or 340 may include a RAM memory card. The recording A2 104b can with buttons 142 (please refer 1B ) to allow the user to the system 100 signal to enter a voice command mode or voice memorandum record mode.
The operation of the system 100 when processing a voice command will now be explained in connection with an example. If no phone call is taking place (ie the phone 102 is suspended), a user may command that a general speech recognition mode has entered by uttering a particular initiator word (eg, "Cell Port"). The system 100 may also be provided with a "on-premises" capability that allows a voice recognition mode to be entered even when a telephone call is in progress (ie, the telephone 102 is decreased). Alternatively, the user may have a button 142a Press on the outside of the receptacle 104b is provided to the system 100 into a speech recognition mode. Upon receiving the signal to enter the speech recognition mode, the processor sends 320 a message over the receiving IM communication bus 322 to the interface module microprocessor 328 over the UART 338 , The from the microprocessor 320 Sent message is sent according to the API of the system 100 formatted. Upon receipt of the message entering the speech recognition mode, the interface module microprocessor activates 328 the microphone 368 or communicates with it in other ways. When a voice command is used, the interface module microprocessor causes it 328 the system 100 to enter a general speech recognition mode after a prescribed voice command has been issued by the user.
Voice commands issued by the user are via the microphone 368 converted into analog electrical signals and through the near-end CODEX 334 where the analog signals are digitized. The digitized voice commands are then stored in the interface module microprocessor 328 compared to the standard and with customized language models stored in the flash memory. For example, if the user issues the "call home" command, the interface module microprocessor attempts 328 to match these words with the stored word models. Upon finding a match, the interface module microprocessor routes 328 Activities according to the command. Therefore, when the command "call home" is received, a signal for initiating a telephone call in the system's API becomes 100 formatted and sent to the microprocessor 320 the recording A2 104b where the API command is implemented translates into a signal coming from the phone 102 is understood. If the phone related to "home" in the store 324 or 340 stored, the command can be sent to the phone 102 consist of the digits of the telephone number and the transmission command. If the phone 102 Alternatively, the command from the interface module microprocessor may allow access to telephone (number) directories stored in its internal memory 328 in the form of a command to a number from a specific location in the phone 102 to gain and initiate the sending function.
The stage two recording A2 104b provided functions may also include provisions for the recording of voice memoranda. By pressing the corresponding button 142b or by issuing the appropriate voice command, such as "memo record", therefore, the system can 100 be configured to record a voice message.
Such a capability is useful, for example, when, for example, a user desires to remember to do something without having to write down in pencil and paper what to remember what to do. Voice memorandum capability is also useful in recording directions or a telephone number provided by a person at the other end of the communication link. In voice memo recording mode, the voice message is transmitted through the microphone 368 converted into an analog electrical signal and to the near-end CODEC 334 sent where the signal is digitized. The digital voice memo is then processed and passed through the interface module microprocessor 328 compressed and in memory 340 saved. If the user desires to recover the voice memo, the user may choose a button 142c on the picture A2 104b Press and causes a command from the microprocessor 320 over the receiving IM communication bus 322 to the interface module microprocessor 328 sent to the API of the system. The interface module microprocessor 328 then obtain the message from the store 340 Again, the message decompresses, performs signal processing functions, and provides a digital output of the message to the near-end CODEC 334 which converts the memo into an analog signal, then from the amplifier 344 amplified and the speaker or headphones 366 is issued. When the command to play a prerecorded voice memo is in the form of a voice command, recognition of the voice command is routed through the interface module microprocessor 328 the recovery of the voice message from the memory 340 one for the purpose of replaying over the loudspeaker 366 , In addition or as an alternative to replaying over the speaker 366 , the memorandum may be transferred to another device for replay purposes. For example, the memorandum may be from the phone 102 can be sent to a remote phone or device or it can be sent to a computer or an external subsystem 378 to be replayed.
A next level of functionality may be provided by the system 100 in conjunction with a photograph A3 104c be provided. The additional of the recording 104c Provided functions may include the storage of voice memos, directories and customized voice commands in the recording 104 include. As in 6 shown, the functionalities of recording A3 104c completely from the phones A1 102 A2 102b and A3 102c supported. The interface module 106 can be identical to that in conjunction with any recording A1-A4 104a -c and B1-B4 104e -h used inter be facemodul. The functionalities which the recording A3 104c with the recordings A1 104a and A2 104b can be performed in the same way as described above.
The picture A3 104c is with the store 324 sufficient to allow the recording of voice memos, as well as for storing voice commands and directories, which the user in the recording A2 104c were programmed. In addition, in the recording A3 104c A UART may be provided to facilitate the transmission of voice memo and voice command data between the interface module 106 and the up close 104 to synchronize. In general, the voice memo recording function using the recording is A3 104c identical to the function of the recording A2 104b is carried out. The provision of additional memory 324 in the picture A3 104c however, allows voice memos to be recorded in the A3 104c get saved. According to an embodiment of the present invention, voice memoranda may be stored in the recording memory 324 saved as each memorandum is recorded. Alternatively, voice memoranda may initially be stored in the interface module memory 340 be saved and later automatically to the recording memory 324 be transferred when the system 100 the resources are available to complete such a transfer. As yet another alternative, the user may wish to transmit voice memorandum data to the memory 324 in the picture A3 104c For example, initiate by pressing one of the recording A3 104c provided button or by issuing a suitable voice command. A control logic in the recording microprocessor 320 and / or the interface module microprocessor 328 may be provided to control that data already in the memory 324 are overwritten by new data. For example, the user may be notified when the memory 324 is full and it can be put to him to choose whether old data should be overwritten. After the voice memorandum to the recording memory 324 was transferred, then recording A3 104c slightly from the interface module 106 is solvable, for example, be taken to the user's office. The picture A3 104c can then be connected to a device in the office that has a microprocessor and associated speakers, similar to the interface module 106 , to replay stored messages. The UART 402 in the picture A3 104c allows the memo data to be stored in the picture A3 via an associated line 104c be transmitted.
The ability to store customized directories and voice commands in the A3 recording 104c allows the user to customize these custom features in each with a suitable interface module 106 equipped vehicle to use. By the possibility of moving the phone 102 and the recording A3 104c Thus, different users may share an automobile while retaining access to their own directories and commands. Also, the feature is useful when a user leases an automobile that has an interface module 106 is equipped as the entire personalized information of the user in the recording A3 104c can be carried.
Another level of functionality may be through the system 100 in conjunction with the recording A4 104d to be provided. As in 6 shown, the functions of recording A4 104d completely from the phone A3 102c supported, but only partially supported by the phone A1 102 and the phone A2 102b , The picture A4 104d supports the functionality of the A1-A3 phones, 102 -c completely. The additional functionalities over the recording A4 104d provided or enabled, may include a text-to-speech capability. The text-to-speech feature allows the system 100 to convert information received in the form of written text into audible language. However, the text-to-speech feature generally requires a telephone 102 capable of receiving textual information. According to the in 6 example shown, the phone is A3 102c the only phone from vendor A that has e-mail or internet surfing capabilities. In the example of 6 is missing the phones A1 102 and A2 102b the ability to receive information in the form of text and therefore can not fully support the text-to-speech feature. It should be noted, however, that some text-to-speech capability associated with the phones A1 102 and A2 102b may be possible, for example, when information in the display 114 of the phone 102 or 102b such as ID information regarding the caller at the electrical connection part 116 of the phone 102 or 102b is provided, in which case the information to the user as audible language or language information can be reproduced. In addition, the text-to-speech function can be used by other subsystems 378 serve, which are able to provide a textual output signal. In general, the recording provides 104d all the above regarding the shots A1-A3, 104a -c functions described.
The picture A4 104d is with commands in the microprocessor 320 provided to receive textual information from the telephone 102c to support. The one from the phone 102c received information is in the API of the system 100 above the microprocessor 320 formatted and to the interface module 106 via the digital data signal line 308 or the ingest IM communication bus 322 transfer. According to one embodiment of the present invention, the interface module includes 106 for use in conjunction with the A4 recording 104d , an additional processor in the custom interface 348 in a comfortable way on a daughter board 380 can be mounted to perform the text-to-speech function. In general, the processor converts to the custom interface 348 the received text in digitized language, which is then the interface module microprocessor 328 can be forwarded and from there to the near-end CODEC 344 for conversion to an analog audio signal. The analog audio signal is then transmitted through the speakers 366 output. The use of an additional processor in the custom interface 348 which is the normal interface module 106 is desirable in that it allows the use of a special processor to handle the relatively complex text-to-speech translation function. It also allows interface modules 106 not for use with a text-to-speech enabled recording 104 are provided and a telephone 102 to be made cheaper. As alternatives, the interface module microprocessor 328 be sufficiently powerful or robust to perform the text-to-speech function, or it may be an improved interface module 107 with a text-to-speech interface module microprocessor 328 in addition to the normal interface module 106 Tobe offered. As another alternative, an improved microprocessor 320 in the recording or an additional microprocessor in the recording A3 102c be provided to handle the text-to-speech function. Except for allowing additional and / or different functionalities, such as text-to-speech, the capture is A3 104c in general the same as the picture A1 104a and A2 102b ,
In conjunction with the above description of the photographs A1-A4 104a -d and their functional skills, a user can generally use the capabilities of the system 100 select according to the needs and wishes of the user by selecting the appropriate A1-A4 104a d. Therefore, a user who has one of the phones A1-A3 102 -c owns, a system 100 who has basic hands-free skills by recording A1 104a and the interface module 106 buys. By buying the recording A2 104b and an interface module 106 , a user may acquire voice command and voice recording capabilities. The use of the photograph A3 104c in conjunction with an interface module 106 provides the user with a system 100 Allowing voice memos and programmed voice command information in easily transportable A3 recording 104c can be stored. Accordingly, it is the recording A1 104a , A2 104b or A3 104c that determines what capabilities the system provides when used in conjunction with any of the A1 or A2 phones 102 or 102b is used. If the user has a new recording 104 buys to get advanced features or another phone 102 he must also take the interface module 106 do not replace. Furthermore, the same interface module 106 in conjunction with the photographs A1-A3 104a -c find use.
A system 100 , which provides text-to-speech capabilities, is available by using an interface module 106 with an additional or an improved processor and an improved interface module 107 , Recording A4 104d and phone A3 102c , Although the interface module 106 or 107 that in conjunction with the recording A4 104d in this example provides improved capabilities, and it should be noted that except for the text-to-speech function, the recording A4 104d is fully supported by and fully compatible with the general interface module 106 , Similarly, the recording A4 104d with phones A1 or A2 102 or 102b be used.
Further referring to 6 , is there the relationship between the phones B1-B4 102d -g, footage B1-B4 104e -h and the interface module 106 shown. In general, the recordings provide B1-B4 104e -h the four levels of functionality above with respect to the A1-A4 104a -d, but which are designed to be physically and electrically connected to telephones B1-B4 made by manufacturer B. 102d -g are connectable. The recordings B1-B4 104e however, they are designed to work with the same interface module 106 like the pictures A1-A4 104a -d work.
As in 6 Shown are the shots B1 and B2 104e and 104f fully compatible with the phones B1 and B2 102d and 102e , but only partially compatible with the phones B3 and B4 102f and 102g , In addition, the recordings support B3 and B4 104g and 104h completely the functional capabilities of the phones B3 and B4 102f and 102g , but are only partially compatible with the phones B1 and B2 102d and 102e , This situation can occur, for example, when phones B1 and B2 102d and 102e have an older interface used by manufacturer B while phones B3 and B4 102f and 102g use a newer interface. Although the phones B1-B4 102d -g may have the same physical properties, affect changes to the interface, that is used to transfer data to the phones 102d -g and from these to control and send their compatibility with the recordings 104e -H. According to an embodiment of the system 100 where a user uses his phone 102 but has a desire for a shot that has an interface for an earlier model of the phone 102 is designed, provided that the phone 102 and the recording 104 still are physically compatible, can take the picture 104 be upgraded or modified by modifying the memory 324 the recording 104 so that the recording 104 in an appropriate way with the phone 102 can interact.
Modifications of the memory 324 may be performed by transferring the upgrade state to the memory 324 about a physical connection with a component of the system 100 , For example, the recording 104 connected to a personal computer used to download a program upgrade from an Internet website or to read in a new program code distributed on a floppy disk, CD ROM or a storage medium. Alternatively, the interface module 106 connected to a personal computer and a new programming code on the memory 340 of the interface module 106 getting charged. Regardless of whether the recording 104 or the interface module 106 can be used to initially receive the upgraded program code, the in the recording memory 324 , the interface memory 340 or both present code may be modified using the methods described above. If a phone 102 , which can download information from the Internet, is available this phone 102 be used to create a new programming code to upgrade or upgrade the recording 104 and / or the interface module 106 to be used. Another method of upgrading the program code of the system 100 is for the user, an upgraded or upgraded recording 104 Buy a new programming code to upgrade the in the interface memory 340 stored codes. Similarly, an interface module 106 , which contains the necessary code to upgrade the code stored in the recording memory 324 is present. As yet another method for upgrading the memory 324 or 340 present codes, can be the entirety or parts of the memory 324 or 340 through the store 324 or 340 be upgraded or replaced with upgraded programming code.
Modifying the memory 324 to suitably between a new telephone interface and the system's API 100 implement, will not be sufficient if the manufacturer changes with respect to the physical design of the phone 102 has made. Also, changes are related to the memory 324 alone may not be sufficient if, for example, the user has bought a new phone from another manufacturer that has a different physical design. In these cases can be compatibility with the system 100 be regained by buying a new recording 104 compatible with the new phone 102 of the user. The cost of buying a recording 104 are preferably much lower than the cost of both intake 104 as well as an interface module 106 because the interface module originally purchased by the user 106 with the new recording 104 can be used.
The multiprocessor and multiple bus design of the system 100 allowed the system 100 is designed using modular units. In particular, the system looks 100 a recording 104 for at least any combination of physical and electrical characteristics present in held telephones 102 can be found. The system 100 allows the use of a common interface module 106 by transforming the unique physical and electrical characteristics of held phones 102 towards a common electrical and physical interface during recording 104 , Therefore, common system components within the interface module 106 be arranged while special attributes for special phones 102 are required by the recording 104 can be included. In this way, the cost of the system 100 reduced and the flexibility increased.
The application programming interface (API) of the system 100 is the common language that is used to get commands and information between recording 104 and the interface module 106 to communicate. A transfer between the interface of the phone 102 and the system's API 100 takes place in the recording 104 and in particular in the microprocessor 320 , After putting in the microprocessor 320 , commands and information coming from the phone 102 using the API to the interface module 106 over the receiving IM communication bus 322 be transmitted. Commands and data provided by the interface module 106 come from, and from the system 100 , follow the reverse course, taking commands and data contained in the API of the system 100 formatted into the unique interface of the phone 100 at the microprocessor 320 the recording 104 be implemented.
If the system 100 with subsystems 378 in addition to the phone 102 can be connected, an additional processor or a custom interface 348 be provided to implement between the API of the system 100 and the interface of the subsystem 378 to make with which the system 100 connected is. Preferably, the custom interface 348 in the form of an addition or daughter board 380 provided using provided electrical contacts with the interface module microprocessor 328 can be connected. As a result, the connectivity to a variety of other subsystem 378 achievable without changes in relation to the main components of the interface module 106 or the recording currently in use 104 , Alternatively, the subsystem 378 using the API of the system 100 communicate without any implementation being required. For example, this may be for communication with an external subsystem 378 required interface in the interface module 106 available. The customized interface 348 and the daughter board 380 can simply provide a mechanical connection or simply not exist at all, if the interface of the external subsystem 378 in the interface module 106 is available.
As mentioned above, the external subsystem 378 include a variety of electronic devices. The subsystem 378 may include protocol based units and closed ended devices. The protocol-based entities may include networks and buses having associated components or peripherals that are interconnected. Hereinafter, the closed devices are referred to as devices that do not have network layering according to the International Standards Organization (ISO) and typically form an ending communication node in connection with a data stream ending with or originating from such a device, and not typically act as a link or pass device for information or data transmissions. An example of such a closed device may be a Global Positioning System (GPS) useful in providing information related to the location of a vehicle or a hardware device, such as a vehicle sensor, from which data about a particular vehicle component is available the sensor is operatively connected.
In addition to the GPS, the external subsystem 378 an Internet Protocol (IP) stack consisting of multiple network layers that are commonly involved in transmissions using the Internet. The external subsystem 378 may also include an Intelligent Transportation System Data Bus (IDB) and / or an On-Board Diagnostic (OBD) system that deals with the recording and provision of vehicle component information.
The external subsystem 378 may also include a controller area network (CAN) that is discoverable in at least some vehicles and that includes a bus along which multiple vehicle elements communicate to provide information regarding such elements. The CAN is operatively connected to each of the plurality of vehicle devices that transmit, receive, or both transmit and receive desired data. For example, the vehicle devices include transducers or other physical devices for capturing and providing information useful for application software in processing to obtain information which is then transmitted for storage in memory and later transmission or even for immediate transmission without processing, upon receipt of the appropriate request or command. Other available networks may be used instead of the CAN, such as Arcnet, which has a protocol similar to the CAN. If the external subsystem 378 includes one of several vehicle buses, the hardware that is supplied to connect the external subsystem to the interface module 106 such as the daughter board 380 , Provide arrangements to the interface module microprocessor 328 to signal the format of the output signal from the special external subsystem 378 is requested. For example, the daughter board 380 include cabling and the presence or absence of a resistance between two signal paths can be used to provide the microprocessor 328 to indicate the appropriate voltage at which signals to and from the external subsystem 378 to be transferred. For further information regarding obtaining information or data from vehicle devices, see U.S. Patent No. 5,732,074, filed January 16, 1996, assigned to the assignee of the present invention. The external subsystem 378 may also include an analog to digital converter (ADC), a standard serial bus, a universal serial bus (USB), an RS232 connection, a User Datagram Packet / Internet Protocol stack, as well as one or more customized peculiar devices.
Other devices that make up the external subsystem 378 may include a PCMCIA (Personal Computer Memory Card Interface Association) unit that stores a memory direction for storing desired information or data. The external subsystem 378 may also include a device capable of communicating using the Bluetooth protocol and providing a standard protocol for wireless communication of information between separate devices.
Referring now to 7 , there is shown the machine for the recording communication state. Generally located in the system 100 the recording 104 and the interface module 106 in a master and slave relationship. As in 7 shown, expected in the state 702 the recording 104 and in particular the microprocessor 320 a message from the phone 102 , When receiving a telephone message, the recording is received 104 in the state 704 by handling the phone request. After handling the phone request, the recording will arrive 104 then in the state 706 in which the telephone request to the interface module 106 is sent. Next up is the recording 104 a message from the interface module 106 in condition 708 , If from the interface module 106 no message is received, the recording returns 104 then in the state 702 back. A system 100 also has the timer working in cooperation to determine if a message has been received or not. During normal operation and when the interface module 106 has received no response, another pulse or heartbeat is sent out at predetermined times. However, if no response occurs within a time interval associated with the timing of the timer, a hardware reset line is activated to the interface module 106 reset. Becomes an interface module 106 Receive message, the recording will handle the message in the state 710 , whereupon it in the state 702 returns. If no phone message has been received, poll or poll the recording 104 periodically the interface module 106 in the state 712 from. According to an embodiment of the present invention, the recording asks 104 the interface module 106 every 72 ms (ie the heart rate or frequency rate of the recording is 72 ms). After interrogating the interface module 106 in the state 712 , the recording arrives 104 in the state 708 in which she receives a message from the interface module 106 expected. If from the interface module 106 no message within 10 ms of polling the interface module 106 was received, the recording returns 104 in the state 702 back in which she has a phone 102 Message expected. According to an embodiment of the present invention, communications between the recording occur 104 and the interface module 106 at 19200 baud using 8 data bits, one parity bit and no stop bit. However, other communication rates can be used and they can even be changed.
Referring now to 8th , there is the architecture of the software of the interface module 106 showing the relationships among various software objects. In general, the highest-level loop is the digital signal processor object 802 , Therefore, power supply control 804 , Audio control 806 , Flash File System 808 , User interface 810 , Voice memo recording 812 , Speech recognition 814 and recording communication 816 Objects all directly from the main loop 802 be entered. Other software objects or modules are addressed in response to interrupts. Accordingly, communications generate between the recording 104 and the interface module 106 an interrupt that causes the software to enter the UART object 818 arrives.

The course of a typical communication scenario is in 9 shown. In 9 A message A is shown as coming from the phone 102 comes from which they take over the picture 104 to the interface module 106 is transmitted. The answer A comes from the interface module 106 , is about the recording 104 transfer and reach the phone 102 in response a. A second message, message b, comes from the telephone 102 , will be through the recording 104 and comes with the interface module 106 as message B on. The answer B comes from the interface module 106 , passes through the recording 104 and comes on the phone 102 as answer b. Next, the message c is from the interface module 106 comes, shown in the queue and awaits attention. At the line marked "SYNCH 2", the message c is sent to the recording 104 release, recording 104 generates the answer C and the answer C becomes the interface module 106 sent.

In response to this situation, the recording may immediately forward the message A to the phone and the answer A to the inter faculty, while the handling of the message B is delayed by the phone, or the recording may communicate the message B to the interface module as message B while delaying the handling of the message A.
Referring now to 11 , there is a worst case scenario for an interface module. In 11 the message C is on hold in the interface module 106 shown. Shortly after the message C is on hold, the message a becomes the phone 102 received and about the recording 104 the interface module 106 as message A communicates. If the message C is still on hold, then the answer A is the phone 102 in reply a communicates. The message B is then on the phone 102 received and the interface module 106 about the recording 104 as message B communicates. The interface module 106 then sends the answer B over the recording 104 in the phone 102 in response b. Subsequent to receiving the answer b on the phone 102 , a synchronization signal, marked as SYNCH 2, is recorded 104 to the interface module 106 sent and causes the release of the waiting message message. The message C is then sent to the recording 104 and the answer C is taken from the recording 104 delivered to the interface module. Therefore, in this worst-case scenario, the message C can not be handled until the messages A and B have been handled and the synchronization signal has been received.
