Description

Technical Field

[0001] The present invention relates to an electric vehicle identification system for an elevator and an elevator equipped with the electric vehicle identification system. Background Art

[0002] In recent years, electric vehicles (short for "electric bicycles", sometimes also called "battery vehicles") have been widely used due to their convenience. For the purpose of anti-theft and charging, some users will push electric vehicles and take the elevator to take the electric vehicles home. However, due to quality problems with the rechargeable batteries of electric vehicles, spontaneous combustion and fire accidents often occur during the charging process, so it is not desirable to bring electric vehicles into buildings. In addition, the elevator car is a relatively small and enclosed space. If spontaneous combustion or explosion occurs in such a space, the damage is very large. Therefore, in order to prevent users from pushing the elevator into the elevator car and taking it upstairs, many elevators are configured to sound an alarm and prohibit the elevator door from closing when an electric vehicle is detected entering the elevator car.

[0003] As a technology for prohibiting electric vehicles from entering elevators, a recognition system is known, such as Figure 4 As shown, the recognition system is composed of a camera 40 and an image recognition controller 30 connected to the camera. The camera 40 has an image acquisition unit 401 for acquiring images and an alarm issuing unit 402 for issuing an alarm. The image acquisition unit 401 of the camera acquires images and sends them to the image recognition controller 30. The image recognition controller 30 recognizes the received images and sends the recognition results to the elevator control system 20. The elevator control system 20 determines whether the electric vehicle has entered the elevator car based on the received recognition results. When it is determined that the electric vehicle has entered the elevator car, the elevator system 20 sends a control signal to the door control unit 201 to keep the elevator door open, and, for example, sends a control signal to the alarm issuing unit 402 instructing it to issue an alarm by wireless means, thereby prohibiting the elevator door from closing and issuing an alarm to urge the user to move the electric vehicle.

[0004] In the recognition system, the image acquisition of the camera 40, the image recognition of the image recognition controller 30, and the determination of the elevator control system based on the recognition result are repeated until it is determined that the electric vehicle has been moved out of the elevator car. Only when it is determined that the electric vehicle has been moved out of the elevator car, the alarm is lifted, the elevator door is allowed to close, and the elevator can operate normally.

[0005] In the above recognition system, image acquisition and image recognition are performed by different devices such as the camera 40 and the image recognition controller 30 respectively. Therefore, when a failure occurs in the camera 40, the recognition operation of the image controller 30 cannot be terminated.

[0006] Furthermore, in the above-mentioned recognition system, the alarm issuing unit is a function attached to the camera. Therefore, if the camera fails during the alarm, the elevator control system cannot control the alarm issuing unit and may not be able to eliminate the alarm.

[0007] In addition, in the above-mentioned recognition system, since the recognition is based on the images collected by the camera, the accuracy is limited and there may be cases of false detection. For example, when a user pushes a baby stroller or bicycle, which looks similar to an electric vehicle, into the elevator car, it is likely that the baby stroller or bicycle will be mistakenly detected as an electric vehicle, thereby sounding an alarm and prohibiting the elevator door from closing. At this time, the false detection causes the elevator door to be unable to close and the elevator cannot operate normally. The user can only climb the stairs to bring baby strollers, bicycles and other equipment upstairs, which brings great trouble to the user. Summary of the invention

[0008] The present invention provides an electric vehicle identification system for an elevator and an elevator equipped with the electric vehicle identification system, which can prevent safety accidents caused by electric vehicles entering the elevator car, and even if it is mistakenly detected that the electric vehicle has entered the elevator car, the alarm can be properly removed and the elevator can resume normal operation.

[0009] One aspect of the present invention relates to an electric vehicle identification system for an elevator, wherein the elevator is provided with an elevator control system for controlling the overall operation of the elevator, the elevator control system is provided with a door control unit for controlling the opening and closing of the elevator door, and an alarm unit capable of issuing an alarm through either voice or light, and is characterized in that the electric vehicle identification system is provided with an intelligent camera, which is arranged in the elevator car and comprises: an image acquisition unit for acquiring an image in real time at least after the elevator door has opened the door; an image recognition unit for recognizing the image acquired by the image acquisition unit; and a determination unit for determining whether there is an electric vehicle in the car according to the recognition result of the image recognition unit, the intelligent camera is connected to the elevator control system, and when the determination unit determines that there is an electric vehicle in the car, the intelligent camera sends an alarm signal to the elevator control system, and the elevator control system is controlled according to the received alarm signal so that the door control unit maintains the elevator door in an open state and the alarm unit issues an alarm for urging the electric vehicle to be moved out of the car.

[0010] One aspect of the present invention relates to an electric vehicle identification system for an elevator, wherein the elevator control system starts timing from the moment the alarm signal is received, and the elevator control system performs control so that: before the timing time reaches the specified time, when the determination unit determines that there is no longer an electric vehicle in the car, the alarm of the alarm device is canceled and the elevator door is allowed to close; when the timing time reaches the specified time, the alarm of the alarm device is canceled, the elevator door is closed, and the elevator starts to go up or down.

[0011] One aspect of the present invention relates to an electric vehicle identification system for an elevator, wherein the elevator is provided with a door closing button in the car for accepting a door closing operation by a user, and after the determination unit determines that there is an electric vehicle in the car, when the user long presses the door closing button until the elevator door is completely closed, the elevator control system cancels the alarm of the alarm.

[0012] Another aspect of the present invention relates to an elevator equipped with the above-mentioned electric vehicle identification system.

[0013] Effects of the Invention

[0014] According to the above-mentioned electric vehicle identification system for elevators and elevators, safety accidents caused by electric vehicles entering the elevator car can be prevented, and even if it is mistakenly detected that an electric vehicle has entered the elevator car, the alarm can be appropriately released and the elevator can resume normal operation.

[0022] Hereinafter, the electric vehicle identification system for an elevator according to the present invention will be described with reference to the accompanying drawings.

[0023] 〈Structure of electric vehicle identification system for elevators〉

[0024] The electric vehicle identification system involved in the present invention is mainly used in elevators running up and down along a shaft. The elevator (hereinafter referred to as the elevator) generally has an elevator control system that controls the overall operation of the elevator. The elevator control system has at least a door control unit that controls the opening and closing of the elevator door, and an alarm unit that can issue an alarm.

[0025] Figure 1 This is a block diagram showing an electric vehicle identification system for an elevator according to the present invention.

[0026] like Figure 1 As shown, in the elevator, the elevator control system 2 includes a door control unit 21 that controls the opening and closing of elevator doors, and an alarm unit 22 that can issue an alarm, for example, by either voice or light.

[0027] In addition, the elevator is also equipped with an electric vehicle identification system for prohibiting electric vehicles from entering the elevator car. The electric vehicle identification system is mainly composed of an intelligent camera 1, which is connected to the elevator control system 2 and controlled by the elevator control system 2.

[0028] In the electric vehicle identification system for elevators involved in the present invention, briefly speaking, when the electric vehicle identification system 1 recognizes that an electric vehicle has entered the car, the smart camera 1 sends an alarm signal to the elevator control system 2, and the elevator control system 2 controls according to the received alarm signal, so that the door control unit 21 maintains the elevator door in an open state, and the alarm unit 22 sends an alarm to urge the electric vehicle to be moved out of the car.

[0029] Hereinafter, the configuration of each part of the electric vehicle identification system 1 according to the present invention will be described in detail.

[0030] In the electric vehicle identification system 1 for elevators of the present invention, the smart camera 1 is installed in the car, for example, on the ceiling of the car, etc., where it is convenient to shoot the situation in the car.

[0031] like Figure 1 As shown, the intelligent camera 1 includes: an image acquisition unit 11, which acquires images in real time at least after the elevator door is opened; an image recognition unit 12, which recognizes the image acquired by the image acquisition unit 11; and a determination unit 13, which determines whether there is an electric vehicle in the car based on the recognition result of the image recognition unit 12.

[0032] The bicycle recognition system has a power switch (not shown) for turning on and off the power supply of the smart camera 1. By providing the power switch, the smart camera can be turned off by the power switch when a malfunction occurs in the smart camera, and can be restarted by the power switch when the smart camera is in operation for a long time.

[0033] In addition, the power switch is provided in a place shielded from passengers in the car, for example, in a dark box not exposed in the car, and the power switch is provided on a switch control panel of the car operating panel. The so-called passengers refer to ordinary users of the elevator, excluding maintenance personnel and administrators of the elevator. Thus, only maintenance personnel or administrators can operate the power switch, which can prevent ordinary users from operating the power switch without authorization.

[0034] The image acquisition unit 11 is configured to always acquire images in the elevator in real time, but it can also be configured to be in a standby state at all times and to be activated and acquire images only when necessary. For example, after the elevator door is opened, it can be expected that a user may enter the elevator. At this time, it is necessary to detect whether a user has entered the elevator by pushing an electric vehicle. Therefore, the image acquisition unit 11 is activated to acquire images in real time.

[0035] The image acquisition unit 11 sends the acquired image to the image recognition unit 12, and the image recognition unit 12 recognizes the received image.

[0036] Specifically, an electric vehicle recognition model is provided in the above-mentioned smart camera 1, and images of electric vehicles of different shapes and different states are pre-stored in the electric vehicle recognition model. The so-called shape refers to the outer contour shape of the electric vehicle, and in particular includes characteristic parts that can distinguish the electric vehicle from ordinary bicycles, such as the seat, pedals, windshield, and rearview mirror. As is well known, electric vehicles have different appearance designs depending on the brand and model. Therefore, in order to improve the recognition accuracy, it is preferred to include images of electric vehicles of various shapes as much as possible in the electric vehicle recognition model. Different states include, for example, a state in which the electric vehicle is not obstructed, and a state in which a part of the electric vehicle is obstructed by a person or an object.

[0037] After receiving the image from the image acquisition unit 11, the image recognition unit 12 recognizes the received image. At this time, the entire image can be recognized, but it is preferred to limit the recognition to only the specified area in the car in the above image. By recognizing only the specified area in the car, when someone pushes an electric vehicle and just passes by the elevator door, but the electric vehicle is captured in the image, it can avoid the situation being mistakenly detected as an electric vehicle entering the elevator.

[0038] When the image recognition unit 12 recognizes an image, it compares the image with the electric vehicle image in the electric vehicle recognition model. If the electric vehicle image with a similarity of more than a predetermined threshold value exists in the electric vehicle recognition model, it is recognized that the image contains an electric vehicle. If the electric vehicle image with a similarity of more than a predetermined threshold value does not exist in the electric vehicle recognition model, it is recognized that the image does not contain an electric vehicle. The predetermined threshold is, for example, 80%, but is not limited thereto and can be arbitrarily set according to actual needs.

[0039] The image recognition unit 12 sends the recognition result to the determination unit 13, and the determination unit 13 makes a determination based on the recognition result. Specifically, when the image recognition unit 12 recognizes that the image contains an electric car for the first time after the elevator door has opened, the determination unit 1 determines that the electric car has entered the car as a situation where the electric car exists in the car, and when the image recognition unit 12 recognizes that the image contains an electric car after the determination unit 13 determines that the electric car has entered the car, the determination unit 13 determines that the electric car has not been moved out of the car as a situation where the electric car exists in the car, and when the image recognition unit 12 recognizes that the image no longer contains an electric car, the determination unit 13 determines that the electric car has been moved out of the car as a situation where the electric car does not exist in the car.

[0040] When the determination unit 13 determines that there is an electric vehicle in the car, the smart camera 1 sends an alarm signal to the elevator control system 2. The elevator control system 2 performs control according to the received alarm signal, so that the door control unit 21 maintains the elevator door in an open state, and the alarm unit 22 issues an alarm to urge the electric vehicle to be moved out of the car.

[0041] Here, the alarm unit 22 of the elevator control system 2 uses, for example, a speaker built into the elevator to broadcast the contents of the alarm. The speaker may be installed in the car, above the car, below the car, or in the elevator lobby. The installation location is not particularly limited as long as the alarm voice can be transmitted to passengers in the car.

[0042] The alarm unit 22 is a component of the elevator control system 2, and is not subordinate to the smart camera 1. Therefore, the elevator control system 2 can independently control the broadcast content, playback time, playback order, etc., regardless of the smart camera 1. For example, in the case of a temporary crash or permanent failure of the smart camera 1, the elevator control system 2 can control the alarm unit 22 to release the alarm.

[0043] In addition, regarding the broadcast content, playback time, and playback order, for example, an alarm of "Do not drive the electric vehicle into the elevator" may be issued as soon as the electric vehicle is recognized to have entered the elevator car, and an alarm of "Please drive the electric vehicle out of the elevator" may be issued after a certain period of time, for example, 5 seconds, when the electric vehicle has not been moved out of the elevator car. Here, the specific content of the alarm is not limited to the above examples and can be set arbitrarily. When the alarm of "Please drive the electric vehicle out of the elevator" is issued, the alarm may be issued at regular time intervals, or the interval time of issuing the alarm may be shortened as time passes. By shortening the interval time of issuing the alarm, the user can feel the urgency, and the user can be effectively urged to move the electric vehicle out of the elevator.

[0044] The alarm unit 22 is not limited to the above-mentioned speaker, but may be an alarm lamp, and the alarm lamp flashes to give an optical alarm. The alarm lamp may be installed at a position visible to passengers in the car, and is preferably installed in the car.

[0045] When the identification and determination of whether there is an electric vehicle in the car is performed based on the collected images as described above, it is inevitable that there is a false detection that there is an electric vehicle in the car when there is actually no electric vehicle in the car. If such a false detection occurs, the alarm continues to sound, the elevator door cannot be closed, and the elevator cannot operate normally.

[0046] According to the electric vehicle identification system 1 for an elevator of the present invention, even if the above-mentioned false detection occurs, the alarm can be appropriately canceled and the elevator can resume normal operation.

[0047] Hereinafter, a method for canceling the alarm and restoring the elevator to normal operation will be specifically described.

[0048] <Method 1 to clear the alarm and restore the elevator to normal operation>

[0049] The elevator control system 2 also has a timing unit (not shown), which starts timing from the moment the elevator control system 2 receives the alarm signal. Since the time required for image acquisition, recognition and determination after the electric vehicle enters the car is extremely short and negligible, the moment when the elevator control system 2 receives the alarm signal can be regarded as the moment when the electric vehicle enters the car. Therefore, the timing time of the elevator control system from the moment the alarm signal is received is equivalent to the elapsed time since the electric vehicle entered the car.

[0050] Before the above-mentioned timing time, i.e., the time elapsed since the electric car entered the car, reaches the specified time, for example, 3 minutes, when the determination unit 13 determines that there is no longer an electric car in the car and the electric car has been moved out of the car, the elevator control system 2 controls the alarm unit 22 to stop issuing an alarm, i.e., to cancel the alarm, and allows the door control unit 2 to control the elevator door to close. At this time, if the pre-set time for the elevator door to close automatically has been reached (for example, a few seconds after the elevator door is opened, or a few seconds after the destination floor is pressed), or a user operates the door closing button for accepting the door closing operation, the elevator door closes, the elevator starts to go up or down, and resumes normal operation. Here, the specified time is set to 3 minutes, but it is not limited to this, and can be appropriately set as needed, and can be appropriately shortened or extended.

[0051] When the above-mentioned timing time, i.e., the time elapsed since the electric car entered the car, reaches the above-mentioned prescribed time, i.e., 3 minutes, the elevator control system 2 controls to release the alarm of the alarm unit 22, and causes the door control unit 21 to control the elevator door to close. In other words, as long as the time elapsed since the electric car entered the car reaches the preset prescribed time, even if the determination unit 13 determines that there is an electric car in the car and the electric car has not been moved out of the car, the alarm is released, the elevator door is closed, and the elevator starts to go up or down. This setting is because, if the electric car has not been moved out of the car after the prescribed time after entering the car, a false detection may occur. At this time, if the alarm is not stopped, it will damage the user's experience. If the elevator door is not allowed to close, it will affect the normal operation of the elevator. Therefore, in this case, the present invention forcibly releases the alarm, closes the elevator door, and restores the normal operation of the elevator.

[0052] <Method 2 to clear the alarm and restore the elevator to normal operation>

[0053] The elevator is equipped with a door closing button in the car for accepting the user's door closing operation. After the determination unit 13 determines that there is an electric car in the car, if the user presses and holds the door closing button until the elevator door is completely closed, the elevator control system cancels the alarm of the alarm unit 22 and restores the elevator to normal operation.

[0054] By setting it in this way, when the user determines that there is no electric car in the elevator, the user can make an operation according to his own judgment to cancel the alarm of the alarm unit and restore the normal operation of the elevator. Therefore, it is possible to avoid the elevator from being unable to operate normally due to false detection while increasing the degree of freedom of use.

[0055] The electric vehicle identification system 1 for elevators of the present invention can be set with the above two ways of releasing the alarm and restoring the elevator to normal operation at the same time, or any one of them can be selected and set according to needs, or neither of them can be set.

[0056] Next, the operation of the electric vehicle identification system 1 for an elevator according to the present invention will be described.

[0057] 〈Action 1 of the electric vehicle identification system for elevators〉

[0058] Figure 2 1 is a flowchart showing the first action of the electric vehicle identification system for elevators according to the present invention, and the first action corresponds to the first action of releasing the alarm and restoring the elevator to normal operation. Figure 2 The flowchart of operation 1 of the electric vehicle identification system for elevators is described.

[0059] After the elevator door is opened, the electric vehicle identification system for the elevator starts to operate.

[0060] The image acquisition unit 11 acquires the image in the car and sends the acquired image to the image recognition unit 12 (step S1).

[0061] Next, the image recognition unit 12 recognizes the received image and sends the recognition result to the determination unit 13 (step S2). Specifically, the image is compared with the electric vehicle image in the electric vehicle recognition model. If there is an electric vehicle image with a similarity of more than a predetermined threshold value with the image in the electric vehicle recognition model, it is recognized as a recognition result that the image contains an electric vehicle. If there is no electric vehicle image with a similarity of more than a predetermined threshold value with the image in the electric vehicle recognition model, it is recognized as a recognition result that the image does not contain an electric vehicle.

[0062] Next, the determination unit 13 determines whether there is an electric vehicle in the car based on the recognition result of the image recognition unit 12 (step S3). Specifically, if it is recognized in the above step S2 that the image contains an electric vehicle, it is determined that the electric vehicle has entered the car as the case where the electric vehicle exists in the car (step S3 is yes), and if it is recognized in the above step S2 that the image does not contain an electric vehicle, it is determined that the electric vehicle has not entered the car as the case where the electric vehicle does not exist in the car (step S3 is no).

[0063] Next, when it is determined in the above-mentioned step S3 that there is no electric car in the car (step S3 is No), the elevator door is allowed to close and the elevator operates normally (step S4).

[0064] Next, when it is determined in the above-mentioned step S3 that there is an electric vehicle in the car (step S3 is yes), that is, the electric vehicle has entered the car on its own, the smart camera 1 sends an alarm signal to the elevator control system 2, and the elevator control system 2 controls according to the received alarm signal, so that the door control unit 21 maintains the elevator door in an open state, and the alarm unit 22 sends an alarm to urge the electric vehicle to be moved out of the car (step S5).

[0065] Next, the elevator control system 2 starts timing after receiving the alarm signal (step S6).

[0066] Next, until the counted time reaches a predetermined time, for example, 3 minutes (No in step S6), steps S1 to S6 are repeatedly executed.

[0067] When it is identified in the above-mentioned step S2 that the image no longer contains the electric car, in step S3 it is determined that the electric car does not exist in the car and has been moved out of the car (step S3 is no), and the processing proceeds to step S4, the alarm is lifted, and the elevator door is allowed to close, and the elevator resumes normal operation.

[0068] When it is recognized in step S2 that an electric vehicle is included in the image, it is determined in step S3 that the electric vehicle is present in the car and that the electric vehicle has not been removed from the car (step S3: Yes), and the process proceeds to step S6.

[0069] Steps S1 to S6 are repeatedly executed until the timing time reaches the specified time.

[0070] Next, when the timing reaches the specified time in step S6 (step S6 is yes), the elevator control system 2 cancels the alarm of the alarm unit 22, and causes the door control unit 21 to control the elevator door to close, so that the elevator resumes normal operation and starts to go up or down (step S9). That is, when the timing reaches the specified time, even if the electric car has not been moved out of the car, the alarm is forcibly canceled and the elevator is closed. As a result, the elevator resumes normal operation and starts to go up or down, and the action of the electric car identification system ends.

[0071] 〈Operation 2 of the electric vehicle identification system for elevators〉

[0072] Figure 3 2 is a flowchart showing the second operation of the electric vehicle identification system for elevators according to the present invention. The second operation corresponds to the second mode of canceling the alarm and restoring the elevator to normal operation. Figure 3 The flowchart of the second operation of the electric vehicle identification system for elevators is described.

[0073] In the second operation of the electric vehicle identification system, steps S1 to S5 are the same as those in the first operation of the electric vehicle identification system, and thus repeated descriptions are omitted.

[0074] In step S8, it is determined whether the elevator control system 2 has detected an operation of long pressing the door closing button until the elevator door is closed.

[0075] Next, if it is determined in step S8 that the operation of long pressing the door closing button until the elevator door is closed is not detected (step S8 is no), the processing returns to step S1, and steps S1 to S5 and S8 are repeated until it is determined in step S8 that the operation of long pressing the door closing button until the elevator door is closed is detected.

[0076] Next, when it is determined in step S8 that an operation of pressing the door closing button for a long time until the elevator door is closed has been detected (step S8: Yes), the elevator door is closed and the process proceeds to step S9.

[0077] Next, in step S9, when the elevator door has been completely closed, the alarm is released, the elevator resumes normal operation, and starts to go up or down.

[0078] As a result, the elevator resumes normal operation and starts to move up or down, and the second action of the electric vehicle identification system ends.

[0079] 〈Effect of Electric Vehicle Recognition System〉

[0080] The intelligent camera of the present invention is provided with an image acquisition unit and an image recognition unit, thereby integrating the functions of image acquisition and recognition into one device. Figure 4 Compared with the prior art in which the image acquisition and recognition functions are realized by two devices such as a camera and an image recognition controller, it is possible to avoid the situation in which the recognition mode of the image recognition controller cannot be terminated due to a camera failure.

[0081] In addition, the smart camera of the present invention is configured to send an alarm signal to the elevator control system when the determination unit determines that an electric vehicle has entered the car based on the recognition result of the image recognition unit. Compared with the prior art, in which the recognition result of the recognition image recognition controller is sent to the elevator control system and the elevator control system makes the determination, the processing burden of the elevator control system can be reduced. Moreover, compared with the elevator control system, the smart camera can be more conveniently maintained such as data upgrade, and the recognition accuracy can be more easily improved.

[0082] In addition, the alarm unit of the present invention is a component of the elevator control system, and is not affiliated with the smart camera. Compared with the prior art in which the alarm unit is provided as an alarm function attached to the smart camera, even if the smart camera fails, the alarm unit can be controlled by the elevator control system, thereby avoiding the previous situation where the alarm cannot be cleared due to a camera failure.

[0083] In addition, the electric vehicle identification system of the present invention is configured such that when a predetermined time has passed since the electric vehicle entered the car, even if the electric vehicle has not been moved out of the car, the elevator control system also cancels the alarm of the alarm unit and causes the door control unit to control the elevator door to close. Thus, even if a false detection occurs, since the alarm is forcibly canceled and the elevator is closed, it is possible to avoid the situation where the elevator cannot be used due to a false detection.

[0084] In addition, after the determination unit determines that there is an electric vehicle in the car, the electric vehicle identification system of the present invention can also release the alarm by the user pressing the door closing button for a long time to resume the operation of the elevator. Therefore, the user can make an operation according to his own judgment, release the alarm, and resume the normal operation of the elevator, which can avoid the elevator from being unable to operate normally due to false detection and improve the degree of freedom of use.

[0085] In addition, in the electric vehicle identification system of the present invention, when the image recognition unit recognizes an image, it is limited to only a specified area in the elevator car in the image for recognition. This can effectively prevent the situation where, for example, a person pushing an electric vehicle past the elevator door is mistakenly detected as an electric vehicle entering the elevator.

[0086] In addition, the bicycle recognition system of the present invention has a power switch for turning on and off the power supply of the smart camera, so that when the smart camera fails, the power switch can be used to shut down the smart camera, and when the smart camera is in operation for a long time, the power switch can be used to restart the smart camera. In addition, by arranging the power switch in a place shielded from the user, it is possible to prevent the user from operating the power switch without authorization.

[0087] As described above, the electric vehicle identification system for elevators of the present invention can prevent safety accidents caused by electric vehicles entering the elevator car, and even if it is erroneously detected that an electric vehicle has entered the elevator car, the alarm can be appropriately released and the elevator can resume normal operation.

[0088] The electric vehicle identification system described above can be applied to various elevators, and is particularly suitable for elevators in residential areas.

[0089] Some embodiments of the present invention are described above, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the invention. These embodiments and their variations are included in the scope and spirit of the invention, and are included in the invention described in the claims and their equivalents.
