Description

Technical Field

[0001] This application relates to, but is not limited to, the field of elevator technology, specifically to a delayed door closing device, an elevator system, and a forklift device. Background Technology

[0002] As the tonnage of freight elevators increases, the area inside the elevator car also increases, which often leads to an increase in loading time. One possibility is simply an increase in the quantity of goods; another is that the larger size of the goods makes loading more difficult and requires more careful handling.

[0003] Currently, freight elevators are generally equipped with a delay button, but this button can only be set to a specific delay time to meet the freight elevator's cargo loading needs. Modifying the set delay time requires professional assistance, making it difficult to meet the needs of different usage environments. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a delayed door closing device that can adjust the delayed door closing time of the elevator as needed, which is beneficial to meet the needs of different usage environments.

[0005] This application provides a delayed door closing device, including: a mobile device and an elevator-mounted device; the mobile device and the elevator-mounted device communicate wirelessly; the mobile device includes a delayed signal transmitter configured to transmit a first delayed door closing signal; the elevator-mounted device is installed on an elevator car and electrically connected to an elevator controller, the elevator-mounted device including a delayed signal receiver; the delayed signal receiver is configured to send a second delayed door closing signal to the elevator controller in response to receiving the first delayed door closing signal, so that the elevator controller can control the elevator to be in a delayed door closing state based on the second delayed door closing signal.

[0006] The delayed door closing device provided in this application includes a mobile device and an elevator-mounted device. The elevator-mounted device is installed on the elevator car and moves with the elevator car. The mobile device, however, is independent of the elevator car and can change its position as needed. When delayed door closing is required, such as when loading goods into the elevator car, the mobile device can be positioned near the door of the corresponding floor. When the elevator car reaches that floor, the mobile device and the elevator-mounted device are within a suitable distance range and can cooperate via wireless communication. The first delayed door closing signal sent by the delayed signal transmitter of the mobile device can be received by the delayed signal receiver of the elevator-mounted device, so the elevator controller can control the elevator to maintain the delayed door closing state. When the door can be closed (e.g., after loading the goods), the cooperation between the mobile device and the elevator-mounted device can be disconnected, for example, by moving the mobile device outside the distance achievable by wireless communication. Then, the delayed signal receiver will no longer receive the first delayed door closing signal, and the elevator controller can then control the elevator to close the door normally.

[0007] Therefore, the duration of the delayed closing is determined by the duration of the first delayed closing signal received by the delayed signal receiver, thus realizing the on-demand delayed closing of the elevator. This allows for the adjustment of the elevator's delayed closing time as needed, which is beneficial for meeting the needs of different usage environments. Furthermore, it is not affected by external light and has high stability.

[0008] This application also provides an elevator system, including: an elevator car, an elevator controller, and the elevator carrier device described in the above embodiments, wherein the elevator carrier device is installed in the elevator car and electrically connected to the elevator controller.

[0009] This application also provides a forklift device, including: a forklift and a mobile device as described in the above embodiments, wherein the mobile device is mounted on the forklift. Attached Figure Description

[0026] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0027] like Figure 6 As shown in the figure, this application provides a delayed door closing device, including a mobile device 100 and an elevator-mounted device 200. The mobile device 100 and the elevator-mounted device 200 communicate wirelessly, so they can be used together within a suitable distance range.

[0028] The mobile device 100 includes a delayed signal transmitter 11, which is configured to transmit a first delayed door closing signal.

[0029] The elevator carrying device 200 is configured to be installed on the elevator car 300 (e.g., Figure 1 and Figure 2 (As shown) and electrically connected to the elevator controller 500, such as Figure 6 As shown. The elevator car 300 can be a freight elevator car or a passenger elevator car. The elevator-mounted device 200 includes a delayed signal receiver 21. The delayed signal receiver 21 is configured to send a second delayed door closing signal to the elevator controller 500 in response to receiving a first delayed door closing signal, so that the elevator controller 500 can control the elevator to be in a delayed door closing state based on the second delayed door closing signal.

[0030] The delayed door closing device provided in this application embodiment includes a mobile device 100 and an elevator-mounted device 200. The elevator-mounted device 200 is installed on the elevator car 300 and moves with the elevator car 300. The mobile device 100 is independent of the elevator car 300 and can change its position as needed. When delayed door closing is required, such as when loading goods into the elevator car 300, the mobile device 100 can be positioned near the door of the corresponding floor. When the elevator car 300 reaches that floor, the mobile device 100 and the elevator-mounted device 200 are within a suitable distance range and can cooperate wirelessly. The first delayed door closing signal sent by the delayed signal transmitter 11 of the mobile device 100 can be received by the delayed signal receiver 21 of the elevator-mounted device 200, so the elevator controller 500 can control the elevator to maintain the delayed door closing state. When the door can be closed (e.g., after the goods have been loaded), the coordination between the moving device 100 and the elevator device 200 can be disconnected. For example, the moving device 100 can be moved to a distance beyond the range that wireless communication can achieve. Then the delayed signal receiver 21 will no longer receive the first delayed door closing signal, and the elevator controller 500 can then control the elevator to close the door normally.

[0031] Therefore, the duration of the delayed closing is determined by the duration of the first delayed closing signal received by the delayed signal receiver 21, thereby realizing the on-demand delayed closing of the elevator. This allows for the adjustment of the elevator's delayed closing time as needed, which is beneficial for meeting the needs of different usage environments. Furthermore, it is not affected by external light and has high stability.

[0032] Among them, the delayed signal transmitter 11 and the delayed signal receiver 21 can establish a connection within a suitable distance range through wireless communication methods such as Bluetooth and Wi-Fi to achieve signal transmission.

[0033] In some exemplary embodiments, the mobile device 100 further includes a power supply module, which includes at least one of a power source and a power interface. The power source and the power interface may be provided separately or both.

[0034] The power source can be a battery, such as a rechargeable battery or a non-rechargeable battery, so the mobile device 100 can operate without relying on an external power source, offering good flexibility. The power interface can be connected to an external power source to power the mobile device 100, which helps reduce the cost of the mobile device 100.

[0035] In some exemplary embodiments, the mobile device 100 is a vehicle-mounted device, which is configured to be mounted on a forklift 400 (e.g., Figure 5 (As shown).

[0036] Freight elevator systems requiring delayed door closing often use forklifts 400 for loading, especially heavy-duty, high-opening freight elevators. The forklift 400 picks up goods near the door area and delivers them into the elevator car, then leaves the door area after loading. Therefore, when the forklift 400 and the elevator car 300 are within a relatively close distance (i.e., within the range achievable by wireless communication), loading can be considered to be in progress; when the forklift 400 and the elevator car 300 are no longer within the range achievable by wireless communication, loading can be considered to have ended. Therefore, a moving device 100 can be installed on the forklift 400 to facilitate automatic delayed door closing during loading and to allow the forklift's control system 410 to power the moving device 100, thus eliminating the need for a power supply to the moving device 100 and reducing costs.

[0037] Of course, the mobile device 100 does not have to be installed on the forklift 400. For example, it can be placed on the person loading the goods, and it can be equipped with its own power supply.

[0038] In some exemplary embodiments, the power supply module includes a power interface electrically connected to the forklift's control system 410. The mobile device 100 is configured to be powered on after the forklift 400 is started. The mobile device 100 also includes a first notification module 13, such as... Figure 6 As shown, the first prompt module 13 is configured to issue a power-on prompt signal when the mobile device 100 is powered on.

[0039] When the forklift 400 starts, the forklift's control system 410 is powered on, and the mobile device 100 is also powered on simultaneously. The first notification module 13 then issues a power-on notification signal, allowing the forklift operator to promptly know whether the onboard device is powered on properly. Conversely, when the forklift's control system 410 is powered off, the mobile device 100 also loses power and stops working. Therefore, the start and stop of the mobile device 100 can also be controlled by starting and stopping the forklift 400.

[0040] The type of the first prompt module 13 is not limited, and may include, but is not limited to, any one or more of the following: an audio prompt module, an optical prompt module, and a visual prompt module. Correspondingly, the type of the first prompt signal is not limited, and may include, but is not limited to, an audio prompt signal (which may be a voice signal or a non-voice signal), an optical prompt signal, and a visual prompt signal.

[0041] In one embodiment, the first prompting module 13 includes a first indicator light 131, such as... Figure 3 As shown. The first indicator light 131 is configured to emit a first light signal when power is applied, as a power-on indication signal. The first light signal can be, but is not limited to, a green light.

[0042] In some exemplary embodiments, the mobile device 100 also includes a switch 12 connected between the power supply module and the delayed signal transmitter 11, such as... Figure 3 and Figure 6 As shown, the switch 12 is configured to connect or disconnect the power supply module and the delayed signal transmitter 11. When the switch 12 is open, the delayed signal transmitter 11 is powered on and continuously transmits the first delayed door closing signal. When the switch 12 is closed, the delayed signal transmitter 11 is powered off and stops transmitting the first delayed door closing signal.

[0043] This allows users to easily control the opening and closing of the delay signal transmitter 11 via the switch 12. When a delayed closing time is needed, the delay signal transmitter 11 is turned on by operating the switch 12; when a delayed closing time is not needed, the delay signal transmitter 11 is turned off by operating the switch 12. This improves the convenience of adjusting the delayed closing time and enhances the user experience.

[0044] The type of switch 12 is not limited, and it can be, but is not limited to, buttons, knobs, toggle switches, touch screens, etc.

[0045] In some exemplary embodiments, the mobile device 100 further includes a second prompting module 14, such as... Figure 6 As shown, the second prompt module 14 is connected in series with the delay signal transmitter 11, and is configured to issue an activation prompt signal when the switch 12 connects the power supply module and the delay signal transmitter 11. This allows the forklift operator to know in a timely manner whether the delay signal transmitter 11 is activated.

[0046] The type of the second prompt module 14 is not limited, and may include, but is not limited to, any one or more of the following: an audio prompt module, an optical prompt module, and a visual prompt module. Correspondingly, the type of the second prompt signal is not limited, and may include, but is not limited to, audio prompt signals (which may be voice signals or non-voice signals), optical prompt signals, and visual prompt signals.

[0047] In one embodiment, the second prompt module 14 includes a second indicator light 141, such as... Figure 3 As shown. The second indicator light 141 is configured to emit a second light signal when power is applied, as a power-on indication signal. The second light signal can be, but is not limited to, a green light.

[0048] In some exemplary embodiments, the mobile device 100 further includes a third prompting module 15 connected in parallel with the delayed signal transmitter 11, such as... Figure 6 As shown. Switch 12 is also connected between the power supply module and the third indicator module 15, and connects the power supply module and the third indicator module 15 when the connection between the power supply module and the delayed signal transmitter 11 is disconnected. The third indicator module 15 is configured to issue a shutdown indicator signal when switch 12 disconnects the connection between the power supply module and the delayed signal transmitter 11. This allows forklift operators to promptly know whether the delayed signal transmitter 11 is off.

[0049] The type of the third prompt module 15 is not limited, and may include, but is not limited to, any one or more of the following: sound prompt module, light prompt module, and screen prompt module. Correspondingly, the type of the third prompt signal is not limited, and may include, but is not limited to, sound prompt signals (which may be voice signals or non-voice signals), light prompt signals, and screen prompt signals.

[0050] In one embodiment, the third prompt module 15 includes a third indicator light 151, such as... Figure 3 As shown, the third indicator light 151 is configured to emit a third light signal when powered on, as a closing indication signal. The third light signal can be, but is not limited to, a red light.

[0051] In one embodiment, the mobile device 100 further includes a sound prompt module 152, such as... Figure 4 As shown, the sound prompt module 152 is configured to emit a first sound signal when the switch 12 disconnects the connection between the power supply module and the delayed signal transmitter 11. The first sound signal may be, but is not limited to, a voice signal used to remind the delayed signal transmitter 11 to be turned off.

[0052] The dual alert of light and sound signals allows the forklift operator 400 to be promptly informed that the delayed signal transmitter 11 is not turned on, thus reminding the forklift operator 400 to operate the switch 12 in a timely manner.

[0053] In some exemplary embodiments, the elevator carrier 200 also includes a warning signal transmitter 22, such as... Figure 6As shown, the prompt signal transmitter 22 is configured to issue a second prompt signal indicating no change in car weight in response to receiving a first prompt signal from the elevator controller 500 indicating no change in car weight. The elevator controller 500 may be equipped with a weighing device that can detect the weight of the elevator car 300, so changes in the weight of the elevator car 300 can be detected by the elevator controller 500.

[0054] like Figure 6 As shown, the mobile device 100 also includes a prompt signal receiver 17 and a fourth prompt module 16, the fourth prompt module 16 being electrically connected to the prompt signal receiver 17. The prompt signal receiver 17 is configured to send a third prompt signal indicating no change in car weight to the fourth prompt module 16 in response to receiving a second prompt signal indicating no change in car weight.

[0055] The fourth prompt module 16 is configured to issue a fourth car weight change prompt signal based on the third car weight change prompt signal.

[0056] The prompt signal transmitter 22 and the prompt signal receiver 17 can establish a connection within a suitable distance range through wireless communication methods such as Bluetooth and Wi-Fi to achieve signal transmission.

[0057] In some cases, after the elevator car 300 has been open for a period of time, no goods are loaded, so the weight of the elevator car 300 does not change. If this state is maintained, it will waste elevator resources or affect the normal operation of the elevator. At this time, the indicator signal transmitter 22 of the elevator loading device 200 can send a corresponding indicator signal to the indicator signal receiver 17 of the moving device 100, and the fourth indicator module 16 of the moving device 100 can issue a corresponding easily identifiable indicator signal (i.e., a fourth indicator signal indicating no change in the weight of the car), so that the loading personnel can be informed of the information in a timely manner and take corresponding actions, such as loading and unloading goods as soon as possible or releasing the delayed door closing state in time, so as to avoid wasting elevator resources or affecting the normal operation of the elevator.

[0058] The type of the fourth prompt module 16 is not limited, and may include, but is not limited to, any one or more of the following: sound prompt module, light prompt module, and screen prompt module. Correspondingly, the type of the fourth prompt signal is not limited, and may include, but is not limited to, sound prompt signals (which may be voice signals or non-voice signals), light prompt signals, and screen prompt signals.

[0059] In one embodiment, the fourth prompt module 16 includes an audio prompt module 152, which is configured to emit a second audio signal based on the third car weight no change prompt signal, as a fourth car weight no change prompt signal. The second audio signal may be, but is not limited to, a voice signal used to remind that the car weight has not changed.

[0060] The sound prompt module 152 of the fourth prompt module 16 and the sound prompt module 152 of the third prompt module 15 can be integrated into a single sound prompt device. This single sound prompt device can emit two different prompt sounds based on two different electrical signals, which helps to reduce the production cost of the mobile device 100. The sound prompt device can be a voice prompter.

[0061] Alternatively, the sound prompt module 152 of the fourth prompt module 16 and the sound prompt module 152 of the third prompt module 15 can be set separately. In this case, the sound prompt module 152 of the third prompt module 15 can be connected in series with the third signal light 151, and the sound prompt module of the fourth prompt module 16 can be connected in series with the prompt signal receiver 17.

[0062] The aforementioned power-on, light-on, and light-off indicator lights can be set separately, so their light signals do not affect each other. The three indicator lights can be arranged in a row, such as... Figure 3 As shown. Alternatively, two of the signal lights can be combined into one, in which case the light can represent the two light signals using two different colors (such as green and yellow), different flashing patterns (such as constant on, flashing), or other methods. Alternatively, three signal lights can be integrated into one, in which case the light can represent the three light signals using three different colors (such as green, yellow, and red), different flashing patterns (such as constant on, rapid flashing, slow flashing), or other methods.

[0063] Mobile device 100 may include housing 18, such as Figure 3 and Figure 4 As shown, the switch 12 and the aforementioned indicator light can be located on the same panel of the housing 18, and the sound prompt module 152 can be located on another panel of the housing 18.

[0064] like Figure 1 and Figure 2 As shown in the illustration, this application also provides an elevator system, including: an elevator car 300, an elevator controller 500, and a carrier device 200 as described in any of the above embodiments. The carrier device 200 is installed in the elevator car 300 and electrically connected to the elevator controller 500. The elevator system can be a freight elevator system or a passenger elevator system. The carrier device 200 is configured to cooperate with the mobile device 100 of any of the above embodiments via wireless communication.

[0065] The elevator system provided in this application embodiment has all the above-mentioned beneficial effects because it includes the elevator carrying device 200 of any of the above embodiments, and will not be repeated here.

[0066] In one embodiment, the elevator carrying device 200 is installed on the top of the elevator car 300, such as... Figure 1 and Figure 2 As shown.

[0067] In one embodiment, the elevator controller 500 is equipped with a weighing device configured to detect the weight of the elevator car 300. The elevator controller 500 is configured to send a first indication signal of no change in car weight to the elevator carrier 200 when it is determined that the car weight has not changed within a set period of time after the elevator car 300 doors are opened, causing the indicator signal transmitter 22 of the elevator carrier 200 to send a second indication signal of no change in car weight to the indicator signal receiver 17 of the moving device 100.

[0068] like Figure 5 As shown in the embodiments of this application, a forklift 400 device is also provided, including: a forklift 400 and a moving device 100 as described in any of the above embodiments, wherein the moving device 100 is mounted on the forklift 400.

[0069] The forklift 400 device provided in this application embodiment has all the above-mentioned beneficial effects because it includes the mobile device 100 of any of the above embodiments, and will not be repeated here. The mobile device 100 is configured to cooperate with the ladder-mounted device 200 of any of the above embodiments via wireless communication.

[0070] In one embodiment, the mobile device 100 is installed in the cab of the forklift 400, which makes it convenient for the forklift operator to know the status of the mobile device 100 in a timely manner, and also makes it convenient for the forklift operator to operate the mobile device 100.

[0071] In one embodiment, the elevator system is a high-load, heavy-duty, large-door freight elevator, using a forklift 400 for loading, with a structure and principle (e.g.) Figure 6 and Figure 7 As shown below:

[0072] The delayed door opening device includes a moving device 100 and an elevator-mounted device 200. The moving device 100 and the elevator-mounted device 200 are used together.

[0073] The mobile device 100 includes a delayed signal transmitter 11, an indicator system (including a first indicator light 131, a second indicator light 141, and a third indicator light 151), operation buttons (i.e., switches 12), a prompting device (i.e., an audio prompting module 152), and a prompting signal receiver 17. The circuit diagram is shown below. Figure 8 and Figure 9As shown, the second signal light 141 and the delayed signal transmitter 11 are connected in series to form the first branch, which is connected in parallel with the second branch where the third signal light 151 is located. The switch 12 is connected in parallel with the third branch where the first signal light 131 is located, and the switch 12 is connected in series with the first and second branches. The prompt signal receiver 17 is connected in series with the sound prompt module 152.

[0074] The mobile device 100 is mounted on the forklift 400 and is powered by the forklift's control system 410.

[0075] The elevator carrying device 200 is installed on the top of the car. The elevator carrying device 200 includes a delayed signal receiver 21 and a prompt signal transmitter 22.

[0076] The mobile device 100 and the elevator carrier 200 have a distance requirement for cooperation. That is, they can only be used together within a set distance range. If the distance is too far (for example, the elevator car 300 and the forklift 400 are on different floors, or the forklift 400 is far from the door area), the signal cannot be received.

[0077] After the forklift 400 is started, the mobile device 100, which is connected to the forklift 400 control system, is powered on. The first indicator light 131 (green light) of the mobile device 100 illuminates, indicating that the mobile device 100 is powered on normally. Please refer to... Figure 8 As shown, when the forklift starts, the power supply of the forklift control system 410 supplies power to the moving device 100, and the circuit containing the first signal light 131 is closed, so the light is lit.

[0078] At this time, if switch 12 is in the open state, the second indicator light 141 (green light) illuminates, and the delayed signal transmitter 11 of the mobile device 100 continuously emits the first delayed door closing signal; if switch 12 is in the closed state, the third indicator light 151 (red light) illuminates, the mobile device 100 does not emit the first delayed door closing signal, and the prompting device emits the first audible signal, indicating that the delayed signal transmitter 11 of the mobile device 100 is in the closed state. Please refer to [reference needed]. Figure 8 As shown, when the forklift starts, the power supply of the forklift's control system 410 supplies power to the moving device 100. If the switch 12 is in the closed state, i.e. Figure 8 When the switch 12 is in the open state, the circuit containing the second signal light 141 and the delayed signal transmitter 11 is closed, so the second signal light 141 is lit, and the delayed signal transmitter 11 transmits a delayed door closing signal. If the switch 12 is in the open state, the circuit containing the second signal light 141 and the delayed signal transmitter 11 is open, the circuit containing the third signal light 151 is closed, and the third signal light 151 is lit.

[0079] If the elevator car 300 is not at the floor where the forklift 400 is located, the delayed signal receiver 21 of the elevator carrier device 200 will not receive the first delayed door closing signal, and the elevator system will operate according to normal logic. When the elevator car 300 reaches the floor where the forklift 400 is located, the delayed signal receiver 21 of the elevator carrier device 200 will receive the first delayed door closing signal, and the elevator will remain in the delayed door closing state, that is, keep the door open.

[0080] When the forklift 400 picks up goods near the door area and delivers them into the car, the distance between the moving device 100 and the elevator carrier 200 is relatively short, and they are always within the range that wireless communication can achieve. The elevator carrier 200 continuously receives the delayed door closing signal, and the car door remains open. When the forklift 400 finishes loading the goods and leaves the area near the door area, or when it finishes loading the goods and switches the switch 12 of the moving device 100 to the closed state, the elevator carrier 200 no longer receives the delayed door closing signal, the car door closes, and it operates according to normal logic.

[0081] When the elevator device 200 stops receiving the delayed door closing signal: 1) If the elevator door closes but does not close completely, and the delayed door closing signal is received again, the elevator will stop closing the door and reopen it, returning to the delayed door closing state; 2) If the elevator door closes completely and the delayed door closing signal is received again, the car will operate according to normal logic; however, if the car remains at the loading floor because it has not selected another floor, it can be reopened by calling the external door to return the car to the delayed door closing state.

[0082] When the delayed signal receiver 21 of the elevator carrier device 200 continuously receives the first delayed door closing signal, and after a set time, the weighing device of the elevator controller 500 still does not detect a change in the car weight, the elevator controller 500 sends a signal to the prompt signal receiver 17 of the mobile device 100 through the prompt signal transmitter 22 of the elevator carrier device 200. After receiving the prompt signal, the prompt signal receiver 17 of the mobile device 100 issues a voice prompt through the prompt device (i.e., the sound prompt module 152) to prompt the forklift operator 400.

[0083] When the forklift 400 is powered on, and the mobile device 100 is powered on, if the switch 12 of the mobile device 100 is in the off state, the prompting device will use voice prompts to the forklift 400 operator, and the delay signal transmitter 11 will be in the off state.

[0084] In one embodiment, the circuit diagram of the elevator system is as follows: Figure 10 As shown, after the delayed signal receiver 21 receives the delayed door closing signal, the elevator controller 500 controls the KN relay to close and outputs an open door signal, keeping the elevator doors open. When the prompt signal transmitter 22 transmits a prompt signal indicating no change in car weight, the elevator controller 500 controls the KM relay to close and outputs a close door signal.

[0092] In any one or more of the exemplary embodiments described above, the described functionality may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software, the functionality may be stored as one or more instructions or code on or transmitted via a computer-readable medium and executed by a hardware-based processing unit. The computer-readable medium may comprise a computer-readable storage medium corresponding to a tangible medium such as a data storage medium, or a communication medium comprising any medium facilitating the transfer of a computer program from one place to another, for example, according to a communication protocol. In this manner, a computer-readable medium may generally correspond to a non-transitory tangible computer-readable storage medium or a communication medium such as a signal or carrier wave. The data storage medium may be any available medium accessible by one or more computers or one or more processors to retrieve instructions, code, and / or data structures for implementing the techniques described in this disclosure. Computer program products may comprise computer-readable media.

[0093] For example, and not as a limitation, such computer-readable storage media may include RAM, ROM, EEPROM, CD-ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, flash memory, or any other medium that can be used to store desired program code in the form of instructions or data structures and is accessible by a computer. Furthermore, any connection may also be referred to as a computer-readable medium. For example, if instructions are transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of medium. However, it should be understood that computer-readable storage media and data storage media do not include connections, carrier waves, signals, or other transient media, but rather refer to non-transient tangible storage media. As used herein, disks and optical discs include compact optical discs (CDs), laser discs, optical discs, digital versatile discs (DVDs), floppy disks, or Blu-ray discs, where disks typically reproduce data magnetically, while optical discs use lasers to reproduce data optically. The above combinations should also be included within the scope of computer-readable media.

[0094] For example, instructions can be executed by one or more processors, such as one or more digital signal processors (DSPs), general-purpose microprocessors, application-specific integrated circuits (ASICs), field-programmable logic arrays (FPGAs), or other equivalent integrated or discrete logic circuits. Therefore, the term "processor" as used herein can refer to any of the above-described structures or any other structures suitable for implementing the techniques described herein. Additionally, in some aspects, the functionality described herein can be provided within dedicated hardware and / or software modules configured for encoding and decoding, or incorporated into combined codecs. Furthermore, the techniques can be fully implemented in one or more circuit or logic elements.

[0095] The technical solutions of the embodiments of this disclosure can be implemented in a wide variety of devices or equipment, including wireless mobile phones, integrated circuits (ICs), or a set of ICs (e.g., chipsets). Various components, modules, or units are described in the embodiments of this disclosure to emphasize functional aspects of a device configured to perform the described techniques, but they do not necessarily need to be implemented through different hardware units. Rather, as described above, the various units can be combined in codec hardware units or provided by a collection of interoperable hardware units (including one or more processors as described above) combined with suitable software and / or firmware.
