Description

  The present invention relates to an environment measurement device and an environment measurement system that includes a sensor that measures an ambient environment and can share measurement results among a plurality of devices.

  Some air conditioners (air conditioners), air purifiers, and the like have sensors for measuring the surrounding environment, and perform operation control according to the measurement results. However, the measurement range in a single device is limited, and it is difficult to perform optimal operation control particularly in a wide space such as an office or a store.

  For this reason, it has been proposed to construct a sensor network system with a plurality of devices, and transmit and receive measurement results of sensors between the plurality of devices to perform operation control. In this case, since each device can use ambient environment information in a wider space, more appropriate operation control becomes possible.

  For example, in Patent Document 1, a plurality of human sensors and temperature detection sensors are installed in a common air conditioning area to be air conditioned in common by a plurality of indoor units, and detection results of the human sensors and temperature detection sensors are used. An air conditioning system that controls an indoor unit based on the above is disclosed.

JP, 2013-068415, A

  The air conditioning system disclosed in Patent Document 1 assumes that the device incorporated in the sensor network system is a stationary device such as an air conditioner. In such a case, transmission and reception of sensor information between a plurality of devices may be performed according to a preset communication rule.

  However, when a device such as an air purifier that can move the installation location is included in the sensor network system, the movement of the device may require the setting change of the communication rule. Alternatively, even when a new device is added to the sensor network system, it is necessary to change the setting of the communication rule.

  For example, in a sensor network system configured to transmit and receive sensor information between devices installed in a relatively close place, a device may be moved and installed in a relatively far place . In such a case, a device incorporated in the sensor network system receives sensor information from another device located at a location (e.g., another room) remote from the device and controls the operation control of the device. When used, there is a problem that appropriate control can not be performed. Such a problem can be solved by resetting the communication rule when moving the device, but such resetting causes a burden on the user.

  The present invention has been made in view of the above problems, and in the case of constructing a sensor network system with a plurality of devices and transmitting and receiving measurement results of sensors between the plurality of devices to perform operation control, the devices move. It is an object of the present invention to provide an environment measurement device and an environment measurement system capable of performing appropriate control without resetting communication rules even if they occur or devices are newly added.

  In order to solve the above-mentioned problems, the present invention is an environment measurement device which is constructed of a plurality of devices having sensors for measuring an ambient environment and is incorporated in a sensor network system sharing sensor information among the plurality of devices. Operation control of the own machine can be performed using the sensor information of the own machine and the sensor information received from the other machine incorporated in the sensor network system, and the sensor information from the other machine is received At that time, it is determined whether the received sensor information is valid sensor information that can be used for the operation control of the own machine, and the own machine's own sensor information and the other machine's sensor information determined to be valid are used. It is characterized by performing operation control of the machine.

  According to the above configuration, the environment measurement device performs operation control of the own device using not only the sensor information of the own device but also sensor information transmitted from other devices incorporated in the system. However, instead of using all the received sensor information for the operation control of the own machine, sensor information of other machines that can be used for the operation control of the own machine is automatically selected and determined as valid. That is, sensor information of the other device determined to be invalid is not used for operation control of the own device. In this way, even if there are other aircraft that are moved far from near their own aircraft or moved near to their own aircraft due to movement, the sensor information of such other aircraft is automatically validated / invalidated. Since the determination is made, appropriate control can always be performed without resetting the communication rule. Also, even when a new device is added in the sensor network system, it is possible to automatically determine whether the sensor information of the added device is valid or invalid. Proper control can always be performed without doing it.

  The environment measurement device may be configured to determine that the sensor information is invalid when the sensor information received from another device is received through the relay device.

  According to the above configuration, it is possible to determine that the sensor information received via the relay device is from another device distant from the own device, and invalidates the sensor information. In this way, it is possible to prevent inappropriate control by using sensor information of another device located at a distant place.

  Further, the environment measurement device compares the radio wave intensity of sensor information received from another device with a first threshold, and determines that the sensor information is valid if the radio wave intensity is equal to or greater than the first threshold. When the radio wave intensity is less than the first threshold, the sensor information may be determined to be invalid.

  According to the above configuration, it is possible to determine that the sensor information with small radio field intensity at the time of reception is from another device distant from the own device, and invalidates the sensor information. In this way, it is possible to prevent inappropriate control by using sensor information of another device located at a distant place.

  Further, the environment measurement device compares a difference between a sensor value of sensor information received from another device and a sensor value of sensor information of the own device with a second threshold, and the difference is within the second threshold. In this case, the sensor information may be determined to be valid, and if the difference exceeds the second threshold, the sensor information may be determined to be invalid.

  According to the above configuration, it is possible to determine that the sensor information having a large difference from the sensor value of the sensor information of the own device is from another device distant from the own device, and invalidates the sensor information. In this way, it is possible to prevent inappropriate control by using sensor information of another device located at a distant place.

  Further, the environment measurement device determines the final sensor value based on the sensor information of the own device and the sensor information of the other devices determined to be effective, and the operation control of the own device according to the determined final sensor. It can be configured to do.

  According to the above configuration, the final sensor value is determined from the sensor information of the own machine and the sensor information of the other machine which is validated, and the operation control of the own machine is performed according to the determined final sensor. An optimal final sensor value can be determined according to the type of the vehicle, and as a result, optimal operation control can be performed.

  In order to solve the above-mentioned problems, the present invention is an environment measurement system comprising a sensor network system constructed by a plurality of devices having a sensor for measuring an ambient environment and sharing sensor information among the plurality of devices. At least one of the devices incorporated in the sensor network system is the environment measurement device described above.

  The environmental measurement device and the environmental measurement system according to the present invention are devices incorporated in the sensor network system, and other devices which are moved far from near their own machine or moved far from their own machine due to movement of the machine. Even if such other devices are automatically determined to be invalid, there is an effect that appropriate control can always be performed without resetting the communication rules.

First Embodiment
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of an environment measurement system according to the first embodiment.

  An environment measurement system (hereinafter referred to as the present system) shown in FIG. 1 is a system in which a sensor network is constructed by devices such as a plurality of environment measurement devices and sensor devices. Each device in this system is equipped with a sensor that measures the surrounding environment, and this system can transmit and receive the measurement results of the sensor by wireless communication among multiple devices, and can share the measurement results among multiple devices. ing.

  As environmental measurement devices in this system, the air conditioners 11, 12 and the air cleaners 21, 22 are exemplified. The environment measurement apparatus according to the first embodiment performs operation control of its own device using the sensor measurement results of other devices in addition to the sensor measurement results of its own device.

  Moreover, the sensor apparatus 31-33 is contained in this system. The sensor device here is equipped with a sensor that measures the surrounding environment, and it is possible to transmit the sensor measurement result of its own device to another device, but the sensor measurement result of another device is required for its own operation control. It is not a thing. Examples of such a sensor device include a lighting device and an image forming apparatus. Some illumination devices and image forming apparatuses include a human sensor, and perform operation control by detecting the presence or absence of a person around them. Alternatively, the sensor devices 31 to 33 include those having a plurality of sensors such as a temperature and humidity sensor, a PM 2.5 sensor, an illuminance sensor, and a human sensor. Although the sensor devices 31 to 33 are not environment measurement devices in the present invention, the present system is not limited to one that constructs a sensor network by only the environment measurement devices, and the sensor devices 31 to 33 may be included.

  In this system, the air conditioner 11, the air purifier 21 and the sensor device 31 are disposed in the room R1, the air conditioner 12, the air purifier 22 and the sensor device 32 are disposed in the room R2, and the sensor device 33 is a room It is arranged outside R1 and room R2. The sensor device 33 transmits the sensor measurement result to another device via the relay device 41. The relay 41 assists wireless communication between devices, and is not itself an environment measurement device in the present invention, but the relay 41 may be included in this system. The relay unit 41 is mainly responsible for relaying the transmission of sensor measurement results and operation information in an environment measurement device such as an air conditioner to the central control room. In some cases, transmission and reception of sensor measurement results may be performed via the relay device 41.

  The environment measurement device in the present system performs operation control of the own device using the sensor measurement results transmitted from other devices incorporated in the system, in addition to the sensor measurement results of the own device. However, some of the other devices installed in this system include devices that exist in a place (for example, another room) away from the own machine, and using the sensor measurement results of the devices in such a distant place Rather, proper control can not be performed.

  For this reason, the environment measurement device in the present system receives sensor measurement results from all the other devices incorporated in the sensor network of the present system, but all the measurement results are not used for operation control of the own device. It is characterized in that the measurement results of other machines that can be used to control the operation of the own machine are automatically selected and judged as valid. That is, the measurement results of other machines determined to be invalid are not used for operation control of the own machine. As a result, even if there is another device which has been moved far from the own aircraft due to movement, such other aircraft is automatically judged to be invalid, so it is always appropriate without resetting the communication rule. Control can be performed. Of course, if there is another aircraft which has been moved to a nearby location by movement, the other aircraft is automatically determined to be effective and can be used to control the aircraft. Also, when a new device is added in the sensor network system, it is automatically determined whether the added device is valid / invalid.

  In the first embodiment, a method for selecting sensor measurement results used for operation control of the own machine will be described below. FIG. 2 is a flow chart showing the selection procedure of one environmental measurement device included in the present system.

  First, the sensor information in the sensor provided in the own device is updated (ST1), and the sensor information is transmitted to the other device (ST2). That is, although each environment measurement device stores the measurement result by the sensor of the own machine or another machine in the memory as sensor information, for example, the surrounding environment is measured and stored by the sensor provided with the own machine every predetermined time Sensor information is updated to be the latest measurement result. At the same time, it transmits the latest sensor information of its own device to other devices. The sensor information in the following description includes a plurality of types of sensor values (temperature / humidity, illuminance, human feeling, dust stain degree, odor stain degree, etc.).

  Each environment measurement device receives the sensor information of the other device when it obtains the latest sensor information, as in the case of transmitting the sensor information of its own device to the other device. Then, when sensor information from another device is received (YES in ST3), it is determined whether the received sensor information is valid or invalid for the own device. ST4 to ST8 are steps for determining whether the sensor information is valid or invalid.

  At ST4, it is determined whether or not the received sensor information is received from other than the relay device. For example, in the system shown in FIG. 1, the sensor information of the sensor device 31 received by the air purifier 21 is received from the relay 41. On the other hand, the sensor information of the air conditioners 11, 12, the air purifier 22, or the sensor devices 31, 32 received by the air purifier 21 is received from other than the relay device.

  When transmission and reception of sensor information is performed via a relay, a flag indicating that the transmission is from the relay is added to data transmitted from the relay. The environment measurement device that has received sensor information from another device can determine whether the received sensor information is received from other than the relay device based on the presence or absence of this flag.

  In ST5, it is determined whether the field intensity of the received sensor information is equal to or greater than a threshold (first threshold). At this time, the radio wave intensity changes in accordance with the distance between the receiving device (the own device) of the sensor information and the transmitting device (the other device), and particularly when these devices exist in different rooms. Compared to when in the same room. For this reason, the threshold value is set so that the radio wave intensity is equal to or higher than the threshold when the own machine and another machine are in the same room, and the radio wave intensity is lower than the threshold when the machine is in different rooms. Is preferred. For example, in the system shown in FIG. 1, although the radio wave intensity of the sensor information of the air cleaner 21 or the sensor device 31 received by the air conditioner 11 is equal to or higher than the threshold, the sensor information of the air conditioner 12, the air cleaner 21 or The radio wave intensity is less than the threshold. Even when the own machine and another machine are in the same room, the radio wave intensity may be set to be less than the threshold if the distance is equal to or more than a predetermined distance.

  In ST6, the sensor value of the received sensor information and the sensor value of the own device are compared, and it is determined whether the difference is within the threshold (second threshold). The sensor values to be compared here are, for example, the same kind of sensor values such as temperature and humidity and illuminance. In ST6, if the difference between the compared sensor values is within the threshold, it can be determined that the own machine and the other machine are in the same room, and if the threshold is exceeded, it is determined that the own machine and the other machine are in another room it can.

  For example, when the temperature detected by the wet temperature sensor and the detected humidity differ greatly between the own machine and another machine, it is assumed that one is in a room where the air conditioner is on and the other is in a room where the air conditioner is off Yes, it can be determined that these are in separate rooms. Alternatively, if the detected illuminance by the illuminance sensor differs greatly between the own device and the other device, it can be inferred that one is in a room where the illumination is ON and the other is in a room where the illumination is OFF. It can be determined that it is in another room. Other than this, the difference in the presence or absence of the person due to the human sensor, the difference in the air cleanliness due to the dust sensor (whether the window is open or not), the presence or absence of the odor due to the odor sensor Whether or not or not) also shows a large difference in detection results depending on the location, and can be used to determine whether or not the own aircraft and another aircraft are in the same room.

  If all of ST4 to ST6 are YES, the process proceeds to ST7. At ST7, it is determined that the received sensor information is valid. That is, since the received sensor information is used for control of an own machine, it updates as sensor information.

  On the other hand, when any one of ST4 to ST6 is NO, the process proceeds to ST8. At ST8, it is determined that the received sensor information is invalid. That is, there is a large difference between the sensor information received via the relay (NO in ST4), the small radio wave intensity at reception (NO in ST5) sensor information, or the sensor value of the sensor information of the own machine (NO in ST6) The sensor information can be determined to be from another device distant from the own machine, and the sensor information is invalidated. When the process proceeds to ST8, the received sensor information is not used for control of the own device, and therefore, updating as sensor information is unnecessary. Alternatively, after updating and recording all the received sensor information, a flag indicating invalidity may be added to the sensor information to be invalidated.

  In ST9, the final sensor value in the own machine is determined. The final sensor value here is determined from the sensor detection result of the sensor provided in the own device and the sensor information determined to be valid among the sensor information received from other devices, but the determination method Will be described in a second embodiment described later. In ST10, operation control of the own machine is performed according to the final sensor value. An operation control example of the own machine according to the final sensor value will be described in a third embodiment described later.

  Furthermore, in the present system shown in FIG. 1, a specific example will be described in which the validity / invalidity determination of the sensor information is performed based on the flow procedure of FIG. 2. Table 1 below shows a sensor information table in the case where the air purifier 21 is a self-machine, and sensor information and device information detected by each device (however, the sensor device 33 is omitted) in the present system, It shows the valid / invalid judgment results of other machines.

  In the environment measurement device (own machine: air purifier 21 in this example) that determines whether the sensor information is valid or invalid, when the sensor information is received from another device, the radio wave intensity at the time of reception is measured and stored together with the sensor information. Ru. If (the absolute value of) the threshold in ST5 of FIG. 2 is 50 dBm, for example, the radio wave intensities of the air conditioner 11 and the sensor device 31 are equal to or higher than the threshold, and the radio wave intensities of the air cleaner 22, the air conditioner 12, and the sensor device 32 are less than the threshold It becomes.

  In ST6 of FIG. 2, assuming that the sensor value to be compared is a temperature and the threshold (absolute value) is 3 ° C., for example, the temperature difference between the air conditioner 11 and the air cleaner 21 of the sensor device 31 is within the threshold. The temperature difference between the air purifier 22, the air conditioner 12 and the air purifier 21 of the sensor device 32 exceeds the threshold. Besides, assuming that the sensor value to be compared is humidity and (the absolute value of) the threshold value is 10%, for example, the humidity difference between the air conditioner 11 and the air cleaner 21 of the sensor device 31 is within the threshold and the air cleaner The humidity difference between the air conditioner 12 and the air cleaner 21 of the sensor device 32 exceeds the threshold value. The threshold may be expressed not as an absolute value but as a ratio. For example, if the temperature threshold of the air cleaner 21 (own machine) is ± 10%, the temperature difference with the detected temperature of the air cleaner 21 is ± 10% or less.

  Moreover, in the measurement results of the illuminance sensor and the human sensor, the air conditioner 11 and the sensor device 31 have the same result as the air cleaner 21 (illumination "bright" and human feeling "present"), but the air cleaner 22, air conditioner 12 and the sensor device 32 have different results than the air purifier 21 (illuminance "dark" and human feeling "not"). As described above, also in the case where the measurement result is the same or different in the own machine and the other machine, it is included in the determination whether the difference between the sensor values in ST6 of FIG. 2 is within the threshold. That is, if the measurement results are the same, it is considered to be within the threshold, and when the measurement results are different, it is considered to exceed the threshold.

  In the radio wave intensity and sensor information shown in Table 1, when the air cleaner 21 is the own machine, the sensor information from the air conditioner 11 and the sensor device 31 is valid, and from the air cleaner 22, air conditioner 12 and sensor device 32. Sensor information is invalidated.

  Although the above description exemplifies the case where the valid / invalid determination of sensor information from another device is performed based on the radio wave intensity and the sensor information, the present invention is not limited to this, and other devices may be used. It is also possible to make a determination based on the information. For example, in the case where the own machine performing the validity / invalidity determination is the air conditioner 11, the operation mode of the air conditioner 11 is "cooling", but the operation mode of the air conditioner 12 which is another machine is "stop". As described above, it may be considered that another apparatus different from the own apparatus in the device information such as the operation mode or the like is determined to be in another room and determined as invalid.

Second Embodiment
In the first embodiment, the method of determining the validity / invalidity of sensor information received from another device in the environment measurement apparatus (own device) has been described. In the second embodiment, the sensor information and the validity of the own device are used. A method of determining the final sensor value using the other machine's sensor information will be described.

  As described above in the first embodiment, the final sensor value is determined from the sensor detection result of the sensor provided in the own device and the sensor information determined to be valid among the sensor information received from other devices. However, examples of the method of determination include the following methods.

(First method)
The first method is to use sensor information received from another device with the largest radio wave intensity as a final sensor value. In this case, the other device with the highest field strength is regarded as the other device closest to the own device, and the sensor value received from the other device is the final sensor value. If the sensor information table of the own device is as shown in Table 1 (in this case, the own device is the air cleaner 21), the other device with the highest radio wave intensity is the sensor device 31. The final sensor values are as shown in Table 2 below.

(Second method)
The second method is to use sensor information received from another device with the smallest radio wave intensity as a final sensor value. In this case, the other device with the largest field intensity is regarded as the other device farthest from the own device, and the sensor value received from the other device is the final sensor value. When the sensor information table of the own machine is as shown in Table 1, the other machine with the smallest radio wave intensity is the air conditioner 11. Therefore, the final sensor value in the own machine in this case is as shown in Table 3 below. Become.

(Third method)
In the third method, the sensor value with the largest difference between the sensor value in the own machine and the sensor value in the other machine is used as the final sensor value. When the sensor information table of the own machine is as shown in Table 1, it is the sensor value of the air conditioner 11 that the largest difference in temperature and humidity and odor contamination degree, and the largest difference in dust contamination degree is the sensor device It is a sensor value of 31. Therefore, the final sensor values in the own machine in this case are as shown in Table 4 below.

(4th method)
The fourth method is to set the worst sensor value as the final sensor value among the sensor values of other machines. Here, the worst value may be, for example, high temperature and high humidity when the air conditioner is in the cooling operation, and low temperature and low humidity as the worst value when the air conditioner is in the heating operation. Alternatively, the season may be determined by the calendar function provided by the aircraft, and it may be considered that the hot and humid in summer and the low temperature and low humidity in winter are the worst values. Also, with regard to the degree of dust contamination and odor contamination, the highest sensor value is regarded as the worst value.

  When the sensor information table of the own machine is as shown in Table 1, since the air conditioner 11 is in the cooling operation, the worst value regarding temperature is the sensor value of the air conditioner 11, and the worst value regarding humidity is own machine (air The sensor values of the purifier 21), and the worst values of the degree of dust contamination and the degree of odor contamination are the sensor values of the sensor device 31. Therefore, the final sensor values in the own machine in this case are as shown in Table 5 below.

(5th method)
The fifth method is to use the average value of the validated sensor values as the final sensor value. When the sensor information table of the own machine is as shown in Table 1, an average value is taken with respect to temperature, humidity, dust stain degree and odor degree, and as a result, the final sensor value in the own machine is shown in Table 6 below. It is shown in. With regard to the degree of dust contamination and the degree of odor contamination, when the average value does not become an integer value, it may be taken as an integer value by rounding off to be a final sensor value.

  The above (first method) to (fifth method) give specific examples of the method of determining the final sensor value, but the present invention is not limited thereto. Besides these methods, there is also a method of determining the final sensor value in accordance with the difference in height between the installation position of the own aircraft and the other aircraft. For example, if there is an air purifier placed on the floor, and there is an air conditioner installed near the ceiling among other machines that are considered effective, the height difference from the air purifier that is the own machine is the highest. If the air conditioner is at a certain installation position, the sensor information of the air conditioner can be used as the final sensor value.

  As described above, when the final sensor value is determined from the sensor information of the own machine and the sensor information of another machine that is validated, the optimal final sensor value according to the type of operation control performed by the own machine may be determined. it can.

Third Embodiment
In the third embodiment, a method of performing operation control of the own machine based on the determined final sensor value will be described. Although the following description is an operation control example when the own machine is an air purifier, the present invention is not limited to this, and also when the own machine is other than an air purifier (for example, an air conditioner) is there. Further, as the operation control example in the present invention, various examples can be considered besides the following examples.

  Table 7 below is an example in the case of controlling the operation mode of the own machine according to the temperature difference between the sensor value of the own machine and the final sensor value. As described above, when the temperature difference is small, it is conceivable to set the operation mode of the own device weak and to set the operation mode of the own device stronger as the temperature difference becomes larger. Since this means that temperature unevenness occurs in the space when the temperature difference is large, control is performed to strengthen the operation mode (increase the air volume) and eliminate the temperature unevenness.

  Table 8 below is an example in the case of controlling the set humidity of the own device according to the final sensor value of temperature. As described above, when the temperature is low, it is conceivable to set the set humidity of the own device high and set the set humidity of the own device lower as the temperature becomes higher.

  Table 9 below is an example in the case of controlling the humidifying function of the own device according to the final sensor value of humidity. As described above, it is conceivable to set the humidifying function of the own device to OFF when the humidity is low, and to set the humidifying function of the own device to ON when the humidity is high. This control may be performed when the temperature is equal to or higher than a predetermined temperature (for example, 24 ° C.).

  Table 10 below is an example in the case of controlling the operation mode of the own machine according to the final sensor value of the illuminance. As described above, control is performed such that the operation mode of the own machine is lowered by one step when the illuminance is "dark" without changing the operation mode of the own machine when the illuminance is "bright" (for example, from "medium" It is conceivable to change to “weak”.

  Table 11 below is an example in the case of controlling the operation mode of the own machine according to the final sensor value of human feeling. As described above, it is conceivable to perform control such that the operation mode of the own machine is set to "strong" when there is a human feeling, and the operation of the own machine is stopped when there is no human feeling.

  The following Table 12 is an example in the case of controlling the operation mode of the own machine according to the final sensor value of the degree of dust contamination. Thus, when the degree of dust contamination is low, it is conceivable to set the operation mode of the own machine weak and to set the operation mode of the own machine stronger as the degree of dust contamination becomes higher.

  Table 13 below is an example in the case of controlling the operation mode of the self-machine according to the final sensor value of the odor contamination degree. As described above, when the degree of odor contamination is low, it is conceivable to set the operation mode of the own machine weak and set the operation mode of the own machine stronger as the degree of odor contamination becomes higher.

Fourth Embodiment
The fourth embodiment shows another control example in the present system, and when the operator performs some operation on one device in the present system, the operation is linked to the other device as well. Control example.

  For example, when the operator sets the operation on / off and the operation mode to one of the devices in the system, the device on which the operator operates is set as the own device. Then, it is conceivable that the operation mode of the other device made effective according to the procedure described in the first embodiment is interlocked with the own device. Other than this, it is conceivable to perform the following interlocking operation.

  (A) When the operator sets the on / off timer for one device in this system, interlocking is performed so that the same timer setting can be used for other devices that are enabled for the own device. Let

  (B) If the operator sets the target temperature (or target humidity) for one of the devices in this system, the same target temperature (or target) is also set for other devices that are enabled for the device. Interlocks to set the humidity).

Fifth Embodiment
The fifth embodiment shows another control example in the present system, and in the case where an abnormality occurs in one of the devices in the present system, the control to cause the other machine to automatically perform the complementary operation. It is an example.

  For example, when an abnormality is detected in one of the devices in the system, the device in which the abnormality is detected is used as the own device. Then, it is conceivable to cause the own machine to perform complementary operation with another machine that is validated according to the procedure described in the first embodiment. As a specific example, when a humidifier causes a water shortage and stops the humidification operation, the humidification operation is started in the other device having the humidification function (the other device determined to be effective for the own device). It is conceivable to perform operation control to increase the set humidity or the set humidity.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and embodiments obtained by appropriately combining the technical means disclosed in the different embodiments.
