[0001] This application is a non-provisional application of US Provisional Application No. 61 / 249,227, filed Oct. 6, 2009, and claims priority. The contents of that application are incorporated herein by reference.

  [0002] Over the years, children have enjoyed playing with toys such as dolls, combat dolls, including vehicles such as toy train sets. Toy train sets are sold in many different forms, such as model train sets, remotely controlled sets, and wooden sets.

  [0003] The toy train system of the present invention provides three types of play: (1) free play, (2) sound and light play, and (3) inductive play.

  During free play, the user can play without any electronic interaction and can experience play similar to other systems. In the play of sound and light, the user can get a further dimension of electronic causal play. In guided play, the character gives the user a unique task to complete and suggests a play scenario during play.

  [0004] Toy train systems, including many vehicles and unique interactive training stops and destinations, create a myriad of different play patterns. Children can interact with the toy train system at any time and experience unique play.

[0005] The present invention is generally directed to a toy train system that incorporates electronic technology to provide interactivity between components of the train system and the user.
[0006] There have been many design challenges associated with the present invention based on the desire for low product costs and a rich play experience. Each challenge itself has not been easily solved without additional costs and external circuit complexity. Together, the overall design and cost challenges have eliminated all standard solutions. In order to achieve specific goals related to the present invention, the present invention incorporates dynamic building block features of a Cypress PSoC microcontroller (eg, CY8C21323 available from Cypress Semiconductor Corporation), user modules and internal circuit paths. The list of choices was compiled and simplified (reducing costs), and design challenges were solved (meeting requirements). Cypress PSoC microcontrollers include configurable blocks of analog and digital logic circuits and programmable interconnects. With these configurable blocks, customized peripheral configurations can be created based on design requirements. Cypress PSoC microcontrollers have a dynamic structure and can move blocks in response to specific tasks. In other words, the functionality of the pins of the microcontroller can change dynamically.

  [0007] Since the play component (eg, vehicle) of the present invention is a physically small device, the size of the power supply has been a consideration. Currently, most sound and light toy designs use three batteries, which were not an option due to the large battery size. The play component required the use of smaller sized batteries, such as two “AAA” alkaline batteries. This provides a voltage source of 2.2 to 3.0 VDC throughout the life of the battery. Most low-cost electronic devices operate at 3.3V (2.7V for newer ICs) and above, so these batteries alone cannot support this requirement. One solution is to use a DC-DC converter to raise the battery voltage to 3.3V and adjust the voltage throughout the useful life of the battery. This is typically accomplished with an external DC-DC power IC, but should add unacceptable cost and additional board complexity. To accomplish this, an internal switch mode pump within the Cypress PSoC microcontroller was enabled, allowing the microcontroller and other external devices to operate at either 3.3V or 5V DC. In this configuration, a toy train system according to an embodiment of the present invention within a low cost, less complex PSoC solution was realized.

  [0008] The present invention utilizes both low speed and high speed (eg, about 20 kB / sec or higher) infrared communications. Used by Universal Asynchronous Receiver Transmitter (UART) operating at 1000bps data rate to be modulated on 38kHz carrier to send IR identification system ID code via IR emitter (using low speed infrared transmitter SIR TX) It was done. To achieve this, the output of the UART at the IC pin was inverted and this signal was logically ANDed with a 38 kHz clock signal. This solution would have required an additional IC with appropriate logic gates to implement the INVERTER and AND gate functions. To implement this serial data stream with the present invention, an internal UART transceiver using a PSoC user block and a 38 kHz counter were created. By inverting the UART signal output internally and making the 38 kHz counter a logical AND, the serial data stream was carried to a single output pin without any additional external components.

  [0009] To send an IR data stream or file through an IR emitter (using a high speed infrared transmitter FIR TX), another universal asynchronous receiver transmitter operating at a data rate of 20 kbps to be modulated on a 455 kHz carrier (UART) was required. To achieve this, the output of the UART at the IC pin was inverted and this signal was made logical AND with a 455 kHz clock signal. This solution would have required an additional IC with appropriate logic gates to implement the INVERTER and AND gate functions. To implement this serial data stream with the present invention, an internal UART transceiver using a PSoC user block and a 455 kHz counter were created. By inverting the UART signal output internally and making the 455 kHz counter a logical AND, the serial data stream was carried to a single output pin without any additional external components.

  [0010] To receive a SIR TX signal with a carrier modulated to 38 kHz (using a low-speed infrared receiver SIR RX), an external IR receiver module similar to products produced by Vishay, Sharp, Panasonic etc. is used It was done. The detected signal output is directly connected to the signal pin on Cypress PSoC and internally connected to the active COMPARATOR user block. The comparator generates an internal interrupt when receiving the data stream and sends the input of the UART RX block internally. This comparator uses only one pin of PSoC to not only adjust incoming data lines, but also send a UART RX input.

  [0011] To receive a SIR TX signal with a carrier modulated to 455 kHz (using a fast infrared receiver FIR RX), an external IR receiver module similar to the product produced by Vishay was used. The detected signal output is directly connected to the signal pin on Cypress PSoC and internally connected to the active COMPARATOR user block. The comparator generates an internal interrupt when receiving the data stream and sends the input of the UART RX block internally. This comparator uses only one pin of PSoC to not only adjust incoming data lines, but also send a UART RX input.

  [0012] Another feature of the present invention is the ability to reproduce audible sounds. This usually requires a custom masked ROM IC, requiring several months for machinery maintenance and cannot be easily changed without significant expense and increased time. By using a Cypress PSoC microcontroller and a low cost external SPI FLASH memory IC, audible sound can be played directly from the PSoC to an external speaker. Since FLASH technology is programmable in the circuit, this method allows for a low cost and rapid programming solution. Since it is programmable during development and similarly programmable on the production line, there is no ROM masking charge and no long lead time. This approach utilizes the SPIM, PRS8 and CNTR8 user blocks inside the PSoC and is specific to this design.

  [0013] Another feature of the invention according to one embodiment is that previous versions of the character can be upgraded with newer sound files. This is achieved by using FIR TX and RX file transfer capabilities. When a new toy is introduced into the play set, the new toy sends a new sound file directly to the older toy, thereby updating to the latest revision. This is a seamless process for children's users, but the PSoC microcontroller is reconfigured internally to utilize UART, SPIM and CNTR user blocks to accomplish this task. This dynamic reconfiguration can give the design the flexibility necessary to accomplish all of the above tasks. When new sound files are successfully transferred from one device to the other, these files are stored in the non-volatile memory of the external FLASH IC.

An electronic module including a processor, a transmitter configured to send an infrared signal, a receiver configured to receive the infrared signal, and an output module; and one or more A plurality of destinations removably coupled to the track portion, at least one of the destinations including an electronics module, the electronics module configured to transmit a processor and an infrared signal And an interactive toy train set including a plurality of destinations.

This communication is facilitated by a network 202, such as a peer-to-peer network, as shown in FIG. This network 202 allows multiple vehicles 18 and destinations 104, 108, 112 to communicate effectively without interference from other devices associated with the train system 10 or devices external to the train system 10. Can do. Each device in the train system 10 includes a unique identification represented by a 1-byte code to identify a particular device in all IR transmissions. Communication is performed via an infrared packet. An infrared packet is a sequence of 5 bytes sent via the IR LED in standard UART format (start bit, 8 data bits, end bit). Each IR packet includes (1) (TX_SRC) unique identifier of the transmission source (TRAIN_0 to TRAIN_15), (2) (TX_DST) unique identifier indicating the intended destination for transmission, (3) (TX_MSG) 256 (4) (TX_ERR) error detection, CRC or checksum, and (5) (TX_EOM) a unique transmission end code (0x0D used in the prototype) indicating the end of the packet. Contains one byte. In general, bytes 1 and 5 are the same for all transmissions, bytes 2 and 3 change, and byte 4 changes based on changes in bytes 2 and 3.

  [0075] Each device in the toy train system 10 includes a network record that is a set of variables in the device software that indicates whether a unique device identification has been detected in the IR packet.

  [0076] Each of the vehicles 18 (1) sleep in a low power state to conserve battery power, (2) idle waiting for user interaction or IR reception, and (3) It includes three power modes: playing sound in response to user interaction, sending or receiving IR, or active changing the state of the visible LED. The vehicle 18 also operates in a default state called the listening state, which responds to button presses and various IR transmissions from other vehicles 18 and locations 100. The vehicle 18 also includes a sleep timer that places the vehicle 18 in a sleep mode when a predetermined amount of time has expired. The sleep timer can be reset by pressing any button on the vehicle 18 or when the vehicle 18 outputs a sound file.

  [0077] The vehicle 18 responds to user interaction (pressing a button) by playing a sound file and sending an IR packet. For example, if the user presses the switch 28 on the vehicle, the vehicle 18 plays a sound file ("Hi, I'm Wilson") and sends an IR packet. The vehicle 18 responds to the received IR packet by playing a sound file and possibly sending an IR packet. For example, the vehicle 18 that has received the IR packet sent in the above example plays a randomly selected sound file (for example, “Hi Wilson, I ’m Koko!”). To respond. The vehicle 18 is involved in a conversation (a sequence of one or more randomly selected sound files that are played by two or more vehicles 18 in response to an IR transmission by the vehicle 18 involved in the conversation), or By playing other sound files, it is possible to respond to IR packets from other vehicles. For example, in the example above, Koko responded to Wilson's request to act as the host of the conversation (sent in the TX_MSG byte of the packet addressed to Koko [in the TX_DST byte of the packet)]. The vehicle 18 is positioned by playing one or both of playing a randomly selected sound file and sending an IR packet to be received at one or both of the other vehicles and a particular location 100. It can respond to IR packets received from 100. For example, when the vehicle 18 approaches the position 100, the vehicle 18 detects a change in the state of the button at the position 100 based on the TX_MSG byte sent by the position 100. The vehicle 18 plays a randomly selected sound file (eg, “Loading Chicken”) and sends an IR packet (TX_SRC = TRAIN_WILSON, TX_DST = BROADCAST, TX_MSG = CHICKENS) The location 100 responds by playing a randomly selected sound file ("Be careful with this chicken!"). The vehicle 18 can reproduce the sound file when approaching the position 100. Furthermore, the vehicle 18 can play back a randomly selected sound file when leaving the position 100.

  [0078] The network record is used to determine which vehicle 18 has been selected as a potential client by any vehicle 18 acting as a conversation host. For example, in the above conversation between Wilson and Koko, Wilson examines the stored network record, determines that Wilson received an IR transmission from Koko at some point and recorded the presence of Koko in the network record. As a result, Koko was selected as a potential client.

  [0079] In operation, when switch 28 is first pressed after power-up or in an existing sleep mode, the vehicle sends an IR packet with a HERE_I_AM signal in the TX_MSG byte. After sending this IR packet, the vehicle 18 can play the sound file. During playback of this sound file, the vehicle 18 waits for a HERE_I_AM_RESPONSE message from another vehicle 18 and updates its network record accordingly. If the vehicle 18 receives a HERE_I_AM_RESPONSE message during this waiting time, the vehicle 18 can initiate a transition to the host (Host) state. For example, assume that Frostini and Koko are in an idle state. Wilson is powered on and the Wilson button is pressed. Wilson sends HERE_I_AM. Wilson plays a sound file (about 0.5 seconds long). Wilson waits while the sound file is being played. Koko receives Wilson's HERE_I_AM. Frostini also receives Wilson's HERE_I_AM. Both update their network records accordingly. Koko implements a 55 microsecond variable backoff delay. Frostini performs a variable back-off delay of 110 microseconds. Koko sends HERE_I_AM_RESPONSE to Wilson after 55 microseconds. Wilson receives Koko's HERE_I_AM_RESPONSE during the delay in the sound file and updates his network record. Frostini receives Koko's HERE_I_AM_RESPONSE during the execution of the variable backoff delay and updates its network record. Frostini sends HERE_I_AM_RESPONSE to Wilson after 110 microseconds. Koko and Wilson receive Frostini's HERE_I_AM_RESPONSE and update their network records accordingly. Wilson has finished the sound reproduction delay. Wilson enters host mode because his NR indicates the presence of one or more vehicles (in this case Koko and Frostini). At the end of this 0.5 second period, each of the three vehicles 18 should have recorded the presence of the other two vehicles 18 on their respective network records. At this point, the network is completely up to date. Thereafter, each time the switch 28 is actuated, a transition to the host state of the vehicle can be initiated.

  [0080] In the host state, the vehicle 18 selects another vehicle 18 from its network record and sends an IR packet with HOST_REQUEST in the TX_MSG byte addressed to the selected vehicle 18. The selected vehicle 18 is called a client. The host vehicle 18 waits for a predetermined amount of time (eg, about 3 seconds) to receive the CLIENT_OK byte in the TX_MSG of the IR packet received from the client. If the CLIENT_OK message is not received within this period, the host vehicle 18 exits the host state and returns to the listening state. If a CLIENT_OK message is received before this timeout, the host vehicle 18 can play a randomly selected sound file having content that is particularly relevant to the client vehicle 18. After receiving the final CLIENT_OK message, the host vehicle 18 determines when the conversation has ended and then returns to the listening state. For example, Wilson succeeds in serving as the host of a conversation with Koko (client) by sending a HOST_REQUEST message and receiving a CLIENT_OK message from Koko before the timeout. Wilson then plays a randomly selected sound file and sends a message to the client. The client responds by playing a randomly selected sound file and sending another CLIENT_OK message. The host vehicle 18 responds by playing another sound file and sending another message to the client. When the host vehicle software indicates that the conversation has ended, the host vehicle 18 returns to the listening state. While in the listening state, vehicle 18 responds to various IR messages from other vehicles 18 and location 100. The vehicle 18 does not need to respond to the IR received message during playback of the sound file. The vehicle 18 updates its network record as part of the response to the IR message, regardless of the device to which the message is addressed.

  [0081] FIG. 23 shows a state diagram of the vehicle 18 according to one embodiment of the invention. 24A-K show various flow diagrams of the operation of the vehicle 18 and the sound file output by the vehicle 18 according to one embodiment of the invention. Note that each vehicle 18 may include different sound files than those shown.

  [0082] Each of the level 1 destinations 104 is (1) a sleep-low power state to conserve battery power, (2) an idle-user interaction beacon (in a limited range, a location or a circular locomotive A single IR packet sent at a predetermined interval by) or a sleep timer event or IR reception, and (3) play a sound in response to an active-user interaction and send or receive IR or a visible LED 3 power modes can be included. Some level 1 destinations 104 (eg, tunnels and bridges) send beacons at regular intervals to be detected by vehicles 18 that are close to the destination. This beacon is used by the vehicle 18 in proximity to the destination to initiate sound reproduction and relaying of IR messages to one or both of the other vehicles 18 and the circular garage. Level 1 destination 104 does not have a switch (other than a power switch) to implement user interaction, so the TX_MSG byte does not change. The TX_MSG byte carries one predetermined value in addition to the TX_SRC byte. This value can be a fixed unique value (MSG_BRIDGE) for distinguishing message sources.

  [0083] FIGS. 25-26 show a state diagram of a level 1 destination 104 according to one embodiment of the invention. Specifically, FIG. 25 relates to the level 1 destination of the bridge, and FIG. 26 relates to the level 1 destination of the tunnel.

  [0084] Each of the level 2 destinations 108 is (1) a sleep-low power state to conserve battery power, and (2) an idle-user interaction beacon (in a limited range, at a location or a circular locomotive. A single IR packet sent at a predetermined interval by) or a sleep timer event or IR reception, and (3) play a sound in response to an active-user interaction and send or receive IR or a visible LED 3 power modes can be included.

  [0085] A car wash is an example of a Level 2 destination 108. In one configuration, the car wash machine includes an SPST button (crank button) driven by rotating a crank arm, three SPST buttons called car wash mode buttons, and three visible light LEDs corresponding to the car wash mode buttons, It may include a visible light power indicator LED, two IR transmit LEDs towards the track, three AAA batteries, a speaker, and an SPDT power switch.

  [0086] In operation, the car washer sends IR signals at regular intervals to be detected by the vehicle 18 in proximity to the car washer. The crank arm drives the crank button a plurality of times each time the crank arm rotates. The car wash processor can send the state of the crank button and the car wash mode button in the TX_MSG byte. The state of the crank button is MOVING or NOT_MOVING. Changes in the state of one or both of the car wash mode button and the crank button are: (1) change in beacon TX_MSG indicating the state of these buttons; (2) sound in response to the determined change in the state of these buttons. One or more of the actions of file playback and (3) a change in the state of the visible light LED in response to the determined change in the state of these buttons can be triggered. This beacon is used by a nearby vehicle 18 to initiate sound reproduction and relaying of IR messages to one or both of the other vehicles 18 and the locomotive.

  [0087] Upon power-up, the software in the car wash machine records that the car wash mode button has not been depressed until the car wash mode button is depressed. The car wash software keeps track of which car wash mode button was last pressed. When the car wash mode button is pressed, (1) the CW software plays the SFX_BEEP sound effect. Regardless of the state of the other car wash mode buttons, the SFX_BEEP sound effect is reproduced and the car wash mode LED changes. For example, when the “Washing” button is pressed and the user presses the “Polishing” button, SFX_BEEP is reproduced, the washing LED is turned off, and the polishing LED is turned on. (2) The car wash machine car wash mode LED corresponding to the car wash mode button pressed immediately before is turned on. (3) All other car wash mode LEDs are turned off.

  [0088] When the state of the crank button transitions from NOT_MOVING to MOVING, the car wash machine reproduces a randomly selected sound effect based on the car wash mode button that was pressed immediately before. If the software records that the car wash mode button was not pressed, two responses are made (1) a randomly selected SFX_BUZZ sound effect is played, and (2) all car wash mode LEDs are 3 times Flashes and ends in the OFF state. When the crank button state transitions from MOVING to NOT_MOVING, all the car wash mode LEDs are turned off. The car wash software also records that the car wash mode button has not been pressed.

[0089] FIG. 27 shows a state diagram of a car wash according to one embodiment of the present invention. 28A-B show various flowcharts of the operation of a car wash according to one embodiment of the present invention.
[0090] A repair shop is another example of a Level 2 destination 108. In one configuration, the repair shop has four SPST switches (tool switches), visible light LEDs (power indication LEDs), two IR transmit LEDs towards the track, three AAA batteries, speakers, and SPDT power. And a switch.

  [0091] In operation, the repair shop sends IR signals at regular intervals to be detected by the vehicle 18 proximate to the repair shop. The change in the state of the repair shop tool switch includes (1) the change in the beacon TX_MSG indicating the state of the repair shop tool switch, and (2) the reproduction of the sound file in response to the determined change in the state of the repair shop tool switch. Can cause. This beacon is used by a nearby vehicle 18 to initiate sound reproduction and relaying of IR messages to one or both of the other vehicles 18 and the locomotive.

  [0092] Upon power-up, the repair shop plays the sound file (SFX_BEEP) in both situations (1) when power is applied and (2) when the repair shop goes out of sleep mode. The repair shop power indicator LED remains on as long as power is applied to the repair shop and the repair shop is not in sleep mode. The repair shop responds to changes in the state of the repair shop tool switch by ensuring that any such change in state is sent by one or more beacon packets. Every change in repair shop tool switch state is sent in a beacon packet following this change in state. The beacon packet sends the current state of the repair shop tool switch at regular intervals until such a state changes or until the repair shop enters sleep mode. The press and release states of the repair shop tool switch have sufficient software debounce to avoid accidentally causing a change of state. The repair shop software plays the sound file when it is determined that any repair shop tool switch has been pressed. For example, when it is determined that the screwdriver tool switch is pressed, the software reproduces the SFX_SCREWDRIVER sound file.

  [0093] The repair shop software changes the TX_MSG byte when it is determined that any repair shop tool switch has been pressed or released. Any change in the repair shop tool switch state that would normally activate a new sound file will work whether or not the repair shop is currently playing the sound file. In other words, sound files can be interrupted. For example, a repair shop screwdriver handle is moved to engage a repair shop screwdriver tool switch, thereby playing a sound file. If the handle is released, the repair shop screwdriver tool switch is released and pressed again (including switch debounce time), the repair shop screwdriver tool switch sound file will be played again and any currently played back Interrupt the sound.

[0094] FIG. 29 shows a state diagram of a repair shop according to one embodiment of the present invention. 30A-B show various flowcharts of operation of a repair shop according to one embodiment of the present invention.
[0095] The quarry is another example of a Level 2 destination 108. In one configuration, the quarry is one SPST button (crusher button) that is driven by rotating the arm, one visible light power indicator LED, two IR transmit LEDs towards the track, and three AAAs. A battery, a speaker, and an SPDT power switch can be included.

  [0096] In operation, the quarry sends IR signals at regular intervals to be detected by the vehicle 18 in proximity to the quarry. The change in the state of the quarry crusher button is (1) the change in the beacon TX_MSG indicating the state of the quarry crusher button, and (2) the reproduction of the sound file in response to the determined change in the state of the quarry crusher button cause. This beacon is used by the nearby vehicle 18 to initiate sound playback and relay of IR messages to one or both of the other vehicles and the locomotive.

  [0097] Upon power-up, the quarry will randomly select a sound file (SFX_BEEP) in both situations when power is applied and (2) the quarry wakes up from sleep mode. Play. The power status LED remains on as long as power is applied to the quarry and the quarry is not in sleep mode. The quarry responds to changes in the state of the quarry crusher button by ensuring that any such change in state is sent by one or more beacon packets. Any change in the quarry crusher button state is sent in a beacon packet following this change in state. The beacon packet sends the current state of the quarry crusher button at the regular intervals described above until such a state changes or until the quarry enters sleep mode. The pressed and released state of the quarry crusher button has sufficient software debounce to avoid accidentally causing a change of state.

  [0098] When it is determined that the quarry crusher button has been pressed, the quarry software plays the sound file (SFX_CRUSH). The quarry software changes the TX_MSG byte when it is determined that the quarry crusher button has been pressed or released. Any change in button or switch state that would normally activate a new sound file will work whether or not the quarry is currently playing the sound file. In other words, sound files can be interrupted. For example, a quarry crusher handle rotates and engages a quarry crusher button, thereby playing a sound file. If the handle continues to rotate and the quarry crusher button is released and pressed again (including the button debounce time), the quarry crusher sound file is played again.

[0099] FIG. 31 shows a quarry state diagram according to one embodiment of the present invention. 32A-B show various flowcharts of quarry operations according to one embodiment of the present invention.
[00100] An intersection gate is another example of a level 2 destination 108. In one configuration, the cross gate includes a button to activate the SPST switch, a visible LED on the member (power status LED), two IR transmit LEDs in front of the member, three AA batteries, and an SPDT power switch. Can be included.

  [00101] In operation, the intersection gate sends IR signals at regular intervals to be detected by the vehicle 18 proximate to the intersection gate. This beacon indicates the state of the intersection gate button. This beacon is used by the vehicle 18 to initiate sound playback and relay of IR messages to one or both of the other vehicles 18 and the locomotive.

  [00102] Upon power-up, the power status LED shall remain on as long as power is applied to the crossing gate and the device is not in sleep mode. The cross gate responds to a button press / switch activation by ensuring that any such change in state is sent by one or more beacon packets. Any change in button / switch state is sent in a beacon packet following this change in state. The beacon packet sends the current state of the button / switch at the regular intervals described above until such a state changes or until the cross gate enters sleep mode.

  [00103] The vehicle 18 is the only device that interacts with the intersection gate. When the vehicle 18 approaches the intersection gate, the vehicle 18 detects a beacon packet. The vehicle 18 responds to changes in the TX_MSG byte of the beacon packet as follows. (1) When the vehicle 18 approaches the intersection gate, the vehicle sends one packet to be detected by the circular locomotive. This packet has a format of (a) TX_SRC: train ID, (b) TX_DST: XG ID, and (c) TX_MSG: XG button state. (2) Whenever the vehicle 18 receives a message indicating that the state of the intersection gate button has changed, it sends the same packet as described above. (3) The vehicle 18 reproduces the sound file when the intersection gate button changes. (4) The vehicle 18 does not play any sound file when the vehicle 18 is close to the intersection gate. For example, the vehicle 18 is close to the intersection gate. The vehicle 18 sends an IR code, and the circular locomotive garage detects the IR code. The circular locomotive plays a sound file, and the vehicle 18 does not play a sound file. When the vehicle 18 does not receive a beacon within a predetermined period, the vehicle 18 reproduces a randomly selected sound file.

  [00104] A refueling station is another example of a Level 2 destination 108. In one configuration, the refueling station comprises an SPST switch (fuel nozzle switch) that is actuated by a plastic lever, three SPST buttons (fuel selection buttons), a visible LED (power status LED) on the member, It can include three visible LEDs (fuel selection LEDs), two IR transmit LEDs in front of the member, three AA batteries, a speaker, and an SPDT power switch.

  [00105] In operation, the refueling station sends IR signals at regular intervals to be detected by the vehicle 18 proximate to the refueling station. Changes in the state of the refueling station button and switch are (1) change in beacon TX_MSG indicating the state of the refueling station button and switch, and (2) sound in response to the determined change in the state of the refueling station button and switch. Causes file playback and (3) a change in the state of the visible LED in response to the determined change in the state of the refueling button and switch. This beacon is used by a nearby vehicle 18 to initiate sound reproduction and relaying of IR messages to one or both of the other vehicles 18 and the locomotive.

  [00106] Upon power-up, the power status LED remains on while power is applied to the refueling station and the device is not in sleep mode. The refueling station responds to button presses / switch activations by ensuring that any such change in state is sent by one or more beacon packets. Any change in button / switch state is sent in a beacon packet following this change in state. Beacon packets send the current state of the button / switch at the regular intervals described above until such a state changes or until the refueling station enters sleep mode.

  [00107] The refueling station software tracks which fuel selection button was last pressed. At power up, the refueling station software records that the fuel selection button has not been pressed until the fuel selection button is pressed. When any fuel selection button is pressed, the refueling station software plays a “BEEP” sound effect. The fuel selection LED of the refueling station corresponding to the fuel selection button pressed immediately before is turned on. All other fuel selection LEDs are turned off. Regardless of the state of the other fuel selection buttons, this “BEEP” sound effect is reproduced and the fuel selection LED changes. For example, when the “gas” button is pressed and the user presses the “water” button, the “BEEP” sound effect is reproduced, the gas LED is turned off, and the water LED is turned on. When the fuel nozzle switch is engaged, the refueling station reproduces a randomly selected sound effect based on the fuel selection button that was pressed immediately before. If the software records that the fuel selection button was not pressed, it can make two responses, (1) can play the “BUZZ” sound effect, and (2) all fuel selection LEDs Flashes 3 times and can end in OFF state. When the fuel nozzle switch is disconnected, all fuel selection LEDs are turned off. The refueling station software also records that the fuel selection button has not been pressed.

  [00108] The vehicle 18 is the only device that can interact with the refueling station. When the vehicle 18 comes close to the refueling station, the vehicle 18 can detect the beacon packet. The vehicle 18 responds to changes in the TX_MSG byte of the beacon packet as follows. (1) When the vehicle 18 approaches the refueling station, the vehicle 18 sends one packet to be detected by the circular locomotive when the TX_MSG byte changes. This packet has the form (a) TX_SRC: vehicle ID, (b) TX_DST: refueling station ID, and (c) TX_MSG: refueling station button state. (2) The vehicle 18 reproduces a sound file in some cases when the vehicle 18 comes close to the refueling station. (3) The vehicle 18 reproduces the sound file when it does not receive a beacon within a predetermined period.

  [00111] A circular locomotive is an example of a Level 3 destination 112. In one configuration, the circular locomotive is located in front of the circular locomotive garage pointing to the upper SPST button (Button), six IR transmit LEDs (IR LED on the clock tower (LONG_TX), and the turntable of the circular locomotive garage). Two IR LEDs (PROX_TX), three IR LEDs, one on each roof of the locomotive garage (BAY_TX)) and two IR receiver modules (one module on the clock tower ( LONG_RX) and one module in the central compartment (BAY_RX)), nine visible LEDs (six located in the clock plane, one located on each garage compartment door), two AA batteries, and a speaker And an SPDT power switch.

  [00112] In operation, the garage responds to user interaction (pressing a button) by playing a sound file and sending an IR packet. For example, if the user presses the circular locomotive button, the circular locomotive plays a sound file ("It's a beautiful day in Cuggington") and sends an IR packet (TRAIN_AT_ROUNDHOUSE) . The circular locomotive responds to the received IR packet by playing a sound file and possibly sending an IR packet. For example, the vehicle 18 that has received the IR packet sent in the above example plays a sound file ("Hi Vee!") And responds by sending an IR packet. The circular locomotive responds by playing a sound file ("Hi Wilson!"). The circular locomotive responds to IR packets from the vehicle 18 at location 100 by playing back a randomly selected sound file. For example, when the vehicle 18 approaches the position 100, the vehicle 18 detects a change in the state of the button at the position 100 based on the TX_MSG byte sent by the position beacon. The vehicle 18 plays a sound file (eg, “Loading Chicken”) and sends an IR packet (TX_SRC = TRAIN_WILSON, TX_DST = BROADCAST, TX_MSG = CHICKENS) to which the circular locomotive is randomly selected. Responds by playing a sound file ("Be careful with what chickens!"). The circular locomotive sends beacons that use its PROX_TX at regular intervals. Such a transmission is detected by the vehicle 18 proximate to the wheelhouse of the circular locomotive and can initiate one or both of sound reproduction and IR message transmission to the circular locomotive. For example, Wilson moves onto the turntable and receives a PROX TX HERE_I_AM signal. Wilson plays the sound file ("Hi Vee!") And sends an IR packet (TRAIN_AT_ROUNDHOUSE). The circular locomotive garage reproduces a sound file (“Hi Wilson!”). The circular locomotive sends beacons using the BAY_TX at regular intervals. Such a transmission is detected by the vehicle 18 in the section of the locomotive garage and can initiate one or both of sound reproduction and transmission of an IR message to the locomotive garage. For example, the vehicle 18 enters one of the circular locomotive compartments and receives a SNORE beacon sent by the IR LED of the circular locomotive compartment. The train then plays a randomly selected sound file. The circular locomotive responds to messages from vehicles 18 in the compartment.

  [00113] The locomotive sends a packet in response to a user input (pressing a button) using the LONG_TX IR LED. This packet message is HERE_I_AM and is broadcast to be received by any vehicle 18 that is in close proximity. The circular locomotive LONG_TX packet can be detected within a predetermined distance. Circular locomotive beacon messages are sent using the PROX_TX IR LED. A circular locomotive beacon can be detected within a predetermined distance. The circular locomotive beacon emits IR codes at time intervals (eg, every 150 microseconds) that allow detection of codes within a predetermined period of time. The circular locomotive begins to emit a beacon as soon as the power switch enters the ON position. The circular garage emits a beacon at a carrier frequency of 38 kHz without interruption for any other functions performed by the circular garage. For example, a circular locomotive garage continuously emits a beacon at a predetermined frequency while reproducing a sound file. The circular locomotive stops beacon emission when entering the sleep mode.

  [00114] When the power switch is moved to the ON position, all variables in the circular locomotive software are set to default values. When the circular locomotive exits sleep mode, the circular locomotive stores the state of all variables, including network records. The locomotive garage includes a default state called the listening state and responds to button presses and various IR transmissions from the vehicle 18. The listening locomotive garage sends beacons at regular intervals on its PROX_TX and BAY_TX. The listening round locomotive also has a sleep timer that times out the sleep mode locomotive. When the button is pressed on the circular locomotive, this sleep timer is reset. Playback of the sound file also resets this sleep timer. The sleep timer is also reset by receiving any IR transmission addressed to the circular locomotive.

  [00115] When the button is pressed for the first time after power-on or in an existing sleep mode, the circular locomotive will (1) play a randomly selected sound file and (2) send a HERE_I_AM signal in the TX_MSG byte. Send a packet with. Thereafter, each time the button is pressed, (1) another sound file is reproduced, and (2) a HERE_I_AM packet is sent.

  [00116] The message addressed to location 100 is relayed from vehicle 18 that has detected a change in the state of the button at that location. Based on the TX_SRC byte, the TX_DST byte, and the TX_MSG byte of such transmission, the circular locomotive determines whether or not to play a sound file. When in the listening state, the circular locomotive responds to a message addressed to the circular locomotive. Such a message is sent by the vehicle 18 upon receipt of a message from the circular locomotive PROX_TX. The circular garage responds by playing a randomly selected sound file determined by the TX_SRC byte of the received packet.

  [00117] The locomotive determines whether to further respond to such a message based on the value of the variable (unlockCtr). The unlockCtr variable is incremented each time the garage receives a TX_DST == ROUNDHOUSE message. When the unlockCtr variable reaches a predetermined value, it causes a further response from the garage. When the predetermined value of unlockCtr is reached, the circular locomotive (1) plays a randomly selected sound file and (2) sends a beacon BAY_BROADCAST message on BAY_TX. The circular locomotive continues to send this beacon message at regular intervals until the circular locomotive receives a TRAIN_IN_BAY message. Upon receipt of the TRAIN_IN_BAY message, the garage sends a UNLOCK_X message. After sending the UNLOCK_X message, the round locomotive is delayed for 3 seconds before returning to the listening state. During this delay, the locomotive does not send a beacon on PROX_TX or BAY_TX or respond to any IR transmission.

  [00118] For example, Wilson moves closer to the circular locomotive and receives a HERE_I_AM transmission of the circular locomotive on PROX_TX. Wilson plays the sound file ("Hi Vee!") And then sends TX_SRC = TRAIN_WILSON, TX_DST = ROUNDHOUSE, TX_MSG = TRAIN_AT_ROUNDHOUSE. The circular locomotive receives this transmission and increments unlockCtr. UnlockCtr has reached a certain value, so the circular locomotive is “You've been a hardworking chuger, pull into a bay to get a new horn!” Say. The locomotive garage then begins to display the BAY_BROADCAST beacon on BAY_TX. Wilson enters one of the partitions and receives a BAY_BROADCAST message. Wilson sends a TRAIN_IN_BAY message. The circular locomotive receives the TRAIN_IN_BAY message, says “Here is your new horn!” And sends an UNLOCK_X message. The circular locomotive stops the BAY_TX beacon and starts a 3 second delay without IR TX. Wilson receives the UNLOCK_X message and modifies the RAM to allow playback of the sound file that was previously “locked” in the correct situation. Wilson is removed from the compartment. The 3-second timer of the circular locomotive times out and the circular locomotive returns to the listening state.

[00119] FIG. 40 shows a state diagram of a circular locomotive garage according to one embodiment of the present invention. 41A-G show various flowcharts of operation of a circular locomotive garage according to one embodiment of the present invention.
[00120] In one play scenario, the two vehicles 18 can communicate via infrared signals. When vehicle A is activated (via switch 24), vehicle A plays a sound file (stored in memory 34) from a library of general comments corresponding to vehicle A, via transmitter 38. A unique identification signal (for example, vehicle A) is sent. The identification signal is a code transmitted via infrared rays, and transmits identification information of the transmitting vehicle or component to the receiving vehicle or component. The receiving vehicle or component must process the received identification signal to determine what to “speak” (sound effect or message utterance) or “do” next according to the play pattern. I must. Vehicle A also always “listens” for any incoming infrared transmission (other than the one it generates).

  [00121] When vehicle B is activated (via a switch), vehicle B plays a sound file (stored in memory 34) from a library of general comments corresponding to vehicle B, and transmitter 38 A unique identification signal (e.g., vehicle B) is sent via. Vehicle B also always “listens” for any incoming infrared transmission (other than the one it generates).

  [00122] After vehicle A and vehicle B are actuated and positioned in close proximity to each other, vehicle A that is still "getting up" and "listening" receives vehicle B's identification signal. The processor of vehicle A then examines memory 34 to determine whether to recognize vehicle B's identification signal. If a sound file corresponding to the received ID exists in the unique memory, recognition is determined. If the vehicle A recognizes the identification signal of the vehicle B after processing, the vehicle A will generate a sound file specific to the vehicle B (for example, “Hi Koko” or other words, greetings, words, etc.) And / or perform some other action, and at the end of this sound file, an infrared signal can be sent indicating that the sound file has been output by vehicle A.

  [00123] Vehicle B that is still "getting up" and "listening" also receives vehicle A's identification signal. Vehicle B receives an infrared signal that a sound file (eg, phrase, greeting, word, etc.) has been sent by vehicle A. The vehicle B then checks the memory 34 to determine whether to recognize the vehicle A identification signal. If a sound file corresponding to the received ID exists in the unique memory, recognition is determined. The vehicle B then examines the memory 34 to determine whether it has greeted the vehicle A after power on. If vehicle B has not greeted vehicle A, vehicle B can output a sound file specific to vehicle A (eg, “Hi Wilson” or other phrases, greetings, words, etc.). At the end of the file, an infrared signal can be sent indicating that the sound file has been output by vehicle B.

  [00124] Next, vehicle A receives an infrared signal sent from vehicle B, and vehicle A examines memory 34 to determine whether it has greeted vehicle B after power-up. If vehicle A has already greeted vehicle B, no further reply or sound file will be sent by vehicle A.

  [00125] If the vehicle does not recognize another vehicle's identification signal, the receiving vehicle sends a signal requesting some data file associated with the identification signal. Vehicles having data files associated with specific identification signals send those data files, and the receiving vehicle correlates those data files with the identification signals and stores them in memory 34.

  [00126] For example, vehicle A receives an identification signal from vehicle C, but vehicle A does not recognize vehicle C's identification signal (ie, vehicle A does not have any sound files associated with vehicle C's identification signal). ). Vehicle A sends a signal that is received by vehicle C (or another vehicle in the vicinity of vehicle A), prompts vehicle C, and a sound file associated with the identification signal of vehicle C (eg, a sound file is vehicle A The data file containing the word “Bob” spoken in the voice of the user is sent to the vehicle A via infrared data transfer. This communication can be performed by the high-speed transmitter 38 of the vehicle C and the high-speed receiver 42 of the vehicle A.

  [00127] Vehicle A then stores the file in memory 34 in correlation with the vehicle C identification signal. Vehicle A then plays a greeting specific to vehicle C (eg, “Hi Bob”) and sends an infrared signal at the end of the greeting indicating that the greeting has been sent.

  [00128] If vehicle A receives more than one identification signal within a predetermined amount of time, vehicle A prioritizes the identification signals according to a preset rating system. If there are only two other vehicles 18, vehicle A plays a greeting specific to each of the other vehicles individually, and at the end of each greeting vehicle A indicates that a greeting has been sent. Send infrared signal.

  [00129] If there are more than two other vehicles 18, vehicle A plays a general greeting (eg, "Hi everyonebody") and at the end of this greeting, the general greeting Sends an infrared signal indicating that has been sent. When other vehicles receive a general greeting signal, all other vehicles respond with a unique greeting (eg, “Hi Wilson” at substantially the same time).

  [00130] The toy train system 10 may include multiple level 1 destinations 104. In one play scenario, the level 1 destination 104 periodically sends a destination identification signal via infrared when the switch is activated. This signal is a short-range infrared signal. The destination identification signal is a code transmitted via infrared rays, and transmits identification information of the transmitting vehicle or component to the receiving vehicle or another destination 100 or component. The receiving vehicle or other destination or component receives the identification to determine what to “speak” (sound effect or message utterance) or “do” next according to the play pattern. The signal must be processed.

  [00131] When the vehicle 18 is in proximity to the level 1 destination 104 and receives a destination identification signal, the vehicle 18 counts how many times the same signal has been received. If the vehicle 18 has not consistently received the level 1 destination identification signal a sufficient number of times to equal an elapsed time of about 1 second, the vehicle 18 will sound (e.g., rotating sound, engine sound, Can play a whistle etc.). This means that the vehicle 18 only received a level 1 destination identification signal for a short period of time and did not stop at a particular level 1 destination 104. If the vehicle 18 consistently receives the level 1 destination identification signal a sufficient number of times to equal an elapsed time of about 1 second, it indicates that the vehicle 18 has stopped at the level 1 destination 104. . When the vehicle 18 stops at the level 1 destination 104, the vehicle 18 receives the level 1 destination identification signal and then adds to the received level 1 destination identification signal (and other identification signals). , Send its unique vehicle identification signal. By retransmitting the identification signal of the level 1 destination in this way, the other components of the toy train system 10 that can receive the infrared signal are notified that the specific vehicle 18 has reached the specific destination. it can. In this way, the various components of the toy train system 10 that receive infrared signals sent by the vehicle 18 can determine the state / position of the other vehicle 18 and position 100.

  [00132] When the vehicle 18 stops at the level 1 destination 104, various things can be done based on the state of the particular play pattern. The play pattern can include tasks (eg, the user needs to move the vehicle to a specific destination and / or perform a specific activity). Task issuance is discussed in more detail below. In the play pattern, if the vehicle stops at a level 1 destination and does not receive a task, the vehicle 18 may have something to do with the level 1 destination (eg, “Boy, it is dark in this tunnel. This tunnel is dark))) I can say. In the play pattern, when the vehicle 18 stops at the destination of level 1 and receives a task, the vehicle 18 receives a sound file (eg, “Ok Vee, I ′m at the” as to whether or not the task 18 corresponds to the task. tunnel just like you asked. (Now, you've just come to the requested tunnel.) ").

  [00133] The toy train system 10 may include multiple level 2 destinations 108. In one play scenario, upon activation of the first switch, the level 2 destination 108 periodically sends a destination identification signal via infrared. This signal is a short-range infrared signal. The destination identification signal is a code sent via infrared rays, and conveys identification information of the destination to send the signal to the vehicle or other destination 100 or component on the signal receiving side. The receiving vehicle or other destination or component receives the identification to determine what to “speak” (sound effect or message utterance) or “do” next according to the play pattern. The signal must be processed.

  [00134] When the vehicle 18 is in proximity to the level 2 destination 108 and receives a destination identification signal, it counts how many times the same signal was received. If the vehicle 18 has not consistently received the level 2 destination identification signal a sufficient number of times to equal an elapsed time of about 1 second, the vehicle 18 will be given a sound (eg, a rotating sound, an engine sound, Can play a whistle etc.). This means that the vehicle 18 only received a level 2 destination identification signal for a short period of time and did not stop at a particular level 2 destination 108. If the vehicle 18 consistently receives the level 2 destination identification signal a sufficient number of times to equal an elapsed time of about 1 second, it indicates that the vehicle 18 has stopped at the level 2 destination 108. . When the vehicle 18 stops at a level 2 destination 108, the vehicle 18 receives a level 2 destination identification signal and then adds to the received level 2 destination identification signal (and other related signals). Then, a unique vehicle identification signal is sent. Thus, by retransmitting the level 2 destination identification signal (and other related signals), a particular vehicle 18 has reached a particular destination in other components of the toy train system 10 that receive infrared signals. Let them know. In this way, the various components of the toy train system 10 that receive infrared signals sent by the vehicle 18 can determine the state / position of the other vehicle 18 and position 100.

  [00135] When the vehicle 18 stops at the level 2 destination 108, various things can be done based on the state of the particular play pattern. The play pattern can include tasks (eg, the user needs to move the vehicle to a specific destination and / or perform a specific activity). Task issuance is discussed in more detail below.

  [00136] In the play pattern, if the vehicle 18 stops at a level 2 destination 108 and does not receive a task, the vehicle 18 may do something with the level 2 destination (eg, "I'm almost empty.I "should fill 'er up." In the play pattern, when the vehicle 18 stops at the destination 108 at level 2 and receives a task, the vehicle 18 receives a sound file (eg, “Ok Vee, I'm at the fuel depot just like you asked. (Now you've just come to the refueling station you requested.) "). In addition, level 2 destinations 108 can include activities that can be performed by the user. For example, the refueling station may have a fuel nozzle that can be removed from the fuel pump and positioned in or near the fuel tank on the vehicle 18. The fuel nozzle includes a switch that, when activated, causes transmission of a second infrared signal. When the vehicle 18 receives the second signal, various things can be done based on the state of the play pattern and whether the vehicle has received a task.

  [00137] After receiving the second signal from the level 2 destination 108, if the vehicle 18 does not receive a task, the engine may do something related to the action taken at the level 2 destination (eg, “Mmmmm, diesel fuel is my favorite. (Well, diesel fuel is my favorite food.)”). When the vehicle 18 receives a task, the vehicle 18 fills the sound file as to whether the operation corresponds to the task ("Ok Vee, I've filled up, just like you asked." ) ”) Can be output.

  [00138] The toy train system 10 may include a plurality of level 3 destinations 112. In one play scenario, the level 3 destination 112 can communicate with the vehicle 18. <Activation> of switch 192 on level 3 destination 112 causes level 3 destination 112 to be stored in a sound file (stored in memory 176 from a library of general comments corresponding to level 3 destination 112. And a unique identification signal (eg, a level 3 destination) is sent via transmitter 180. This signal is a long-range infrared signal. The destination identification signal is a code transmitted via infrared rays, and transmits identification information of the destination on the transmission side to the vehicle on the reception side or another destination 100 or a component. The receiving vehicle or other destination processes the received identification signal to determine what to “speak” (sound effect or message utterance) or “do” next according to the play pattern. Must. Level 3 destination 112 also always “listens” for any incoming infrared transmission (other than the one it generates).

  [00139] Vehicle A that is still "getting up" and "listening" receives a level 3 destination identification signal. The processor of vehicle A then examines memory 34 to determine if it recognizes a level 3 destination identification signal. If a sound file corresponding to the received ID exists in the unique memory, recognition is determined. After processing, if vehicle A recognizes a level 3 identification signal, vehicle A outputs a sound file specific to the level 3 destination (eg, “Hi Vee” or other words, greetings, words, etc.) At the end of this sound file, an infrared signal can be sent indicating that the sound file has been output by vehicle A.

  [00140] Level 3 destinations that are still "getting up" and "listening" also receive vehicle A's identification signal. Level 3 destinations receive an infrared signal that a sound file (eg, phrase, greeting, word, etc.) has been output by vehicle A. The level 3 destination then examines memory 176 to determine whether to recognize vehicle A's identification signal. If a sound file corresponding to the received ID exists in the unique memory, recognition is determined. The level 3 destination then examines memory 176 to determine if it has greeted vehicle A after power-up. If the level 3 destination is not greeting the vehicle A, the level 3 destination outputs a sound file specific to the vehicle A (eg, “Hi Wilson” or other phrases, greetings, words, etc.). At the end of this sound file, an infrared signal can be sent indicating that the sound file has been sent by a level 3 destination. Upon receiving the vehicle A identification signal, the Level 3 destination stores it in a temporary memory. This allows level 3 destination 112 to track which vehicle is active during any play session.

  [00141] If vehicle A remains near a level 3 destination, vehicle A continues to receive an infrared signal sent from the level 3 destination, and vehicle A examines memory 34 and powers up Determine if you later greeted a Level 3 destination. If vehicle A has already greeted a level 3 destination, no further reply or sound file will be sent by vehicle A.

  [00142] Level 3 destination 112 may also communicate with Level 1 destination 104 and Level 2 destination 108. When a level 3 destination receives a signal from a level 1 destination or a level 2 destination, the level 3 destination may receive a sound file associated with the destination (eg, “The Fuel depot is up and running. (The refueling station is awake and moving.) "). Upon receiving the level 1 destination identification signal or the level 2 destination identification signal, the level 3 destination stores it in a temporary memory. This allows Level 3 destination 112 to track which destination (eg, Level 1, Level 2, and Level 3) is active during any play session.

  [00143] Level 3 destination 112 may also initiate a task. A task is an activity that can be performed by a user in a play scenario. If the user activates switch 196 on level 3 destination 112, the level 3 destination can initiate a task. Level 3 destination 112 examines memory 176 to determine which vehicle 18 and destination 100 are active. Based on the active vehicle 18 and the destination 100, a Level 3 destination can select a specific vehicle 18 to perform a task at the specific destination, and a sound file (eg, “Wilson, I need you to go to the fuel deposit and get filled up. (Wilson, go to the refueling station and fill it up.) "). The destination at level 3 sends a task signal to the vehicle 18 (eg, vehicle A) and executes the selected task received by the vehicle 18 when in proximity to the destination at level 3.

  [00144] Vehicle A that is still "getting up" and "listening" receives the task signal from the Level 3 destination, processes the task signal, and generates a sound file (eg, "Ok Vee! I'm on my" "Way! (Okay, I'm heading for the future!)"). When vehicle A is operated through train set 10, vehicle A receives a level 1 destination signal and a level 2 destination signal and retransmits those signals along with its identification signal. When a level 3 destination receives an appropriate signal indicating that the task has been completed, the level 3 destination can respond randomly to the completion of the task. Level 3 destinations generate signals to initiate another task, generate signals indicating that vehicle A must return to level 3 destinations for rewards, and celebrations One or more of generating an audio signal having a phrase can be performed.

  [00145] If the level 3 destination chooses to issue a reward upon completion of the task, the level 3 destination can upgrade vehicle A with a new sound effect. A level 3 destination can signal that vehicle A must return to a level 3 destination, and at the level 3 destination, a new sound file is sent to the vehicle via high-speed infrared data transfer. A is transferred to the memory 34 of A. The new sound (s) can include new horns, songs, words, phrases, etc.

  [00146] Upon power-up of a Level 1 destination 104 or Level 2 destination 108, the destination sends a data stream via an infrared signal. This data stream includes the sound file associated with the destination. For example, the refueling station (level 2 destination) sends the word “refueling station” in the voice of each character (vehicle). If the vehicle 18 is in close proximity and receives this data stream during <operation>, it will identify any data related to the identification information and automatically upload the data (if it was not already in memory) be able to. This means that vehicle A only retrieves the word “refueling station” in its own voice and stores it in memory in correlation with the refueling station identification.

  [00147] In addition, vehicle A searches for the word "refueling station" in the level 3 destination voice, and then when vehicle A forwards information to the level 3 destination, To your destination. Temporarily storing the sound file at the destination of level 3 in the memory is invisible to the user and is deleted from the memory of vehicle A after being uploaded to the destination at level 3. This allows level 3 destinations to update their sound without being close enough to be transferred directly to further destinations.

  [00148] The foregoing has been provided for the purposes of illustrating, describing, and describing embodiments of the present invention. Modifications and adaptations to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention. Various features and advantages of the invention are set forth in the following claims.
