[Technical field]

[0001] The present invention relates to a liquid recovery system, a liquid recovery program, and a liquid recovery method. [Background technology]

[0002] Traditionally, when pumping out temporary toilets at construction sites and other facilities, workers would measure the water level of the wastewater, which is made up of excrement such as feces and urine, in the septic tank every day, and when the amount reached a level that required pumping, the workers would contact a pumping company.

[Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2019-88367 A [Patent Document 2] JP 2020-12348 A Summary of the Invention [Problem to be solved by the invention]

[0006] Patent document 1 describes how an alarm device issues a warning depending on the level of sewage, and patent document 2 describes how a request to have the excrement removed is output when the amount of excrement is above a set value.

[0007] However, collection companies for liquids (excrement) such as feces and urine collect liquids upon contact from managers of temporary toilets at construction sites, etc., but there are cases where they have to go to collect liquids in the same direction for two consecutive days, for example. When they have to go in the same direction or in the same area, there is a problem of inefficiency in collection.

[0008] In particular, with the price of gasoline rising sharply in recent years, when waste collection companies have to repeatedly go to collection points in the same direction or in the same area at the same time, there is a problem of wasting energy such as gasoline in addition to the efficiency of collection.

[0009] These problems are not limited to the collection of excrement such as feces and urine, but also occur in the collection of waste oil, waste edible oil, waste liquid, sewage, and sludge.

[0010] An object of the present invention is to improve the efficiency of liquid recovery.

[0011] Another object of the present invention is to reduce the energy required for transportation. [Means for solving the problem]

[0012] A liquid recovery system according to a first aspect of the present invention is a liquid recovery system for recovering liquid having a detection device that detects an amount of liquid, comprising: the liquid recovery system includes a terminal and a server capable of communicating with the detection device; The server, A communication unit capable of communicating with the terminal and the detection device; a mapping unit that displays the liquid amount information received from the detection device on a map displayed on the terminal; a calendar unit that displays the liquid amount information received from the detection device on a calendar displayed on the terminal; A storage unit that stores liquid amount information, map information, and customer information; and a control unit that predicts how the liquid will increase from the change in the amount of liquid detected by the detection device.

[0013] The control unit predicts how the liquid will increase from changes in the amount of liquid in the container, and calculates the estimated day when the liquid will reach the maximum allowable amount of the container.

[0014] The control unit also predicts how the liquid will increase from changes in the amount of liquid in the container, and calculates an estimated value (estimated amount) of the liquid in the future.

[0015] In other words, the present invention provides an estimated date when the liquid will reach the maximum allowable capacity of the container.

[0016] Therefore, for collection areas in the same direction or in the same area with a close estimated date, a collection group can be set up to go and collect liquid, improving collection efficiency and saving energy required for travel.

[0017] The liquid may contain impurities and may have viscosity.

[0018] A liquid recovery system according to a second aspect of the present invention is the liquid recovery system according to the first aspect, the control unit calculates an average amount of liquid accumulated per day by dividing a sum of amounts of liquid detected in the past by a corresponding number of days based on information on the amount of liquid detected by the detection device stored in the memory unit; This liquid recovery system calculates the remaining days by dividing the difference between the maximum allowable amount of the container and the amount of liquid by the average value.

[0019] For example, the sum of the amount of liquid detected over a 90 day period is divided by the number of days, 90, to obtain the average amount of liquid per day.

[0020] In other words, if the amount of liquid in a container is 1800L, divide 1800L by 90 days to find that the average amount of liquid per day is 20L.

[0021] If the maximum allowable capacity of a container is 1000L and the amount of liquid in the container is 800L, then the remaining number of days is 10, calculated by subtracting 800L from 1000L (200L) and dividing that difference by the average value of 20L.

[0022] Knowing the number of days remaining allows the calculation of an estimated date when the liquid will reach the maximum capacity of the container.

[0023] For example, it will be possible to know by when liquid waste such as feces and urine from temporary toilets needs to be pumped out (collected), and priority can be given to temporary toilets whose deadline is approaching.

[0024] Additionally, by knowing the estimated date when the liquid will reach the container's maximum capacity, collection groups can be established to increase collection efficiency.

[0025] In other words, a collection group can be set up to collect liquid from sites in the same direction or in the same area with a nearby estimated date, improving collection efficiency and saving energy required for travel.

[0026] A liquid recovery system according to a third aspect of the present invention is the liquid recovery system according to the second aspect, the calendar unit has an amount prediction calendar that displays an amount of liquid on the terminal, The liquid recovery system includes a volume forecast calendar that displays an estimated date when the liquid will reach the maximum capacity of the container.

[0027] A collection group can be set up to collect liquid from sites in the same direction or in the same area with close estimated dates, improving collection efficiency and saving energy required for travel.

[0028] A liquid recovery system according to a fourth aspect of the present invention is the liquid recovery system according to the third aspect, The calendar unit is a liquid recovery system that sets a threshold value for the amount of liquid detected by the detection device, and changes the color of the customer information displayed on the amount prediction calendar as the estimated date when the liquid will reach the maximum allowable amount of the container when the amount exceeds the threshold.

[0029] In this embodiment, a two-stage threshold is provided, and the color of the tag of the displayed customer information is changed from blue to yellow and from yellow to red.

[0030] The color of the customer information displayed on the quantity forecast calendar is changed, making it easy to see at a glance which sites need to be prioritized for collection.

[0031] A liquid recovery system according to a fifth aspect of the present invention is the liquid recovery system according to the first to fourth aspects, This is a liquid recovery system, wherein the liquid is excrement such as feces and urine, waste oil, waste edible oil, waste liquid, sewage, or sludge.

[0032] The present invention can be used, for example, for pumping (collection) of waste matter such as feces and urine, collection of waste oil, collection of waste edible oil, collection of waste liquid, collection of wastewater, collection of sludge, etc.

[0033] A liquid recovery system program according to a sixth aspect of the present invention is a liquid recovery system program for recovering liquid having a detection device that detects an amount of liquid, the program comprising: the liquid recovery system includes a terminal and a server capable of communicating with the detection device; The program for the liquid recovery system includes: A communication process capable of communicating with the terminal and the detection device; a mapping process for displaying the liquid amount information received from the detection device on a map displayed on the terminal; A calendar process for displaying the liquid amount information received from the detection device on a calendar displayed on the terminal; a storage process for storing liquid quantity information, map information, and customer information; A control process for predicting how the liquid will increase from the change in the amount of liquid detected by the detection device. Execute This is a program for the liquid recovery system.

[0034] Such a program provides the same effects as the liquid recovery system according to the first aspect.

[0035] A program for a liquid recovery system according to a seventh aspect of the present invention is a program for the liquid recovery system according to the sixth aspect, comprising: The control process calculates an average amount of accumulated liquid per day by dividing a sum of amounts of liquid detected in the past by a corresponding number of days based on information on the amount of liquid detected by the detection device stored in the storage process, and This is a program for a liquid recovery system that calculates the number of remaining days by dividing the difference between the maximum allowable amount of the container and the amount of liquid by the average value.

[0036] Such a program provides the same effects as the liquid recovery system according to the second aspect.

[0037] A program for a liquid recovery system according to an eighth aspect of the present invention is a program for the liquid recovery system according to the seventh aspect, comprising: The calendar process includes a quantity prediction calendar process for displaying the quantity of liquid on the terminal, The liquid recovery system program displays an estimated date when the liquid will reach the maximum allowable amount of the container by the amount prediction calendar process.

[0042] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0043] As shown in FIG. 1, a liquid recovery system 10 according to an embodiment of the present invention includes: A detection device 100 that detects the amount of liquid placed on a plurality of user sides; A server 200 to which liquid amount information is transmitted from the detection device 100; A first terminal 300 that is a terminal that can access the server 200; A second terminal 400 which is a user terminal to which the liquid amount information is transmitted from the detection device 100; and a third terminal 500 that is accessible to the server 200 and that allows the recovery staff to check the movement of the liquid during recovery.

[0044] There may be a plurality of first terminals 300, second terminals 400, and third terminals 500, and the number is not limited.

[0045] The detection device 100 includes a container 110 for storing a liquid, A liquid level sensor 120 for detecting the amount of liquid in the container 110; A memory unit 130 that stores information on the amount of liquid detected by the liquid level sensor 120; and a transmitting unit 140 that transmits information about the amount of liquid detected by the liquid level sensor 120 to the server 200.

[0046] The container 110 is a tank for storing liquid, and in this embodiment, is a tank that can store 1000 L.

[0047] The liquid level sensor 120 is a sensor that detects the amount of liquid, and in this embodiment, it measures the distance to the liquid level using an ultrasonic sensor, and measures the amount of liquid from the height of the liquid level.

[0048] Specifically, the liquid level sensor 120 transmits high-frequency ultrasound toward the liquid level of the liquid in the container 110 and receives the high-frequency ultrasound reflected by the liquid surface, and the ultrasonic transmission / reception unit 121 measures the time from transmission to reception of the high-frequency ultrasound.

[0049] The liquid level sensor 120 then converts the time from transmission to reception of the high-frequency ultrasonic wave into distance, and calculates the amount of liquid based on the volume of the container 110.

[0050] The memory unit 130 stores information on the amount of liquid in the container 110 detected by the liquid level sensor 120 .

[0051] The transmitting unit 140 transmits information on the amount of liquid detected by the liquid level sensor 120 .

[0052] Specifically, the transmitting unit 140 transmits information about the amount of liquid stored in the memory unit 130 .

[0053] Information on the amount of liquid detected by the liquid level sensor 120 is transmitted by the transmitting unit 140 to the server 200 and the second terminal 400 which is a terminal on the user side.

[0054] Information on the amount of liquid detected by the liquid level sensor 120 is transmitted at predetermined time intervals to the server 200 and the second terminal 400, which is a user terminal.

[0055] The amount of liquid in the container 110 is detected by the liquid level sensor 120 according to this embodiment once an hour, and the result is stored in the memory unit 130.

[0056] In this embodiment, the information on the amount of liquid stored in the memory unit 130 is transmitted by the transmission unit 140 to the server 200 and the second terminal 400, which is a terminal on the user side, once every 13 hours.

[0057] It should be noted that the information on the amount of liquid transmitted to the second terminal 400 may not be transmitted directly from the detection device 100 to the second terminal 400 but may be transmitted only to the server 200 .

[0058] The liquid amount information may then be transmitted to the second terminal 400 from the server 200.

[0059] Furthermore, a repeater may be provided between the transmitting unit 140 and the server 200 or the second terminal 400 .

[0060] The method of transmission from the transmitting unit 140 to the server 200 or the second terminal 400 may be either wired or wireless.

[0061] Further, short-range wireless communication such as Bluetooth (registered trademark) may be used in addition to WiFi.

[0062] In this embodiment, the liquid level sensor 120 is used as the sensor of the detection device 100, but various sensors such as a liquid level displacement sensor and a liquid amount sensor may be used.

[0063] The server 200 includes a communication unit 210 that can communicate with the detection device 100, the first terminal 300, the second terminal 400, and the third terminal 500, a mapping unit 220 that displays information on the amount of liquid received from the detection device 100 on a map displayed on the first terminal 300 and the third terminal; a calendar unit 230 that displays information on the amount of liquid received from the detection device 100 on a calendar displayed on the first terminal 300 and the third terminal; An alert unit 240 that notifies the user of a change in the amount of liquid; A customer information management unit 250 that manages customer information; A server storage unit 260 that stores liquid amount information, map information, list information, alert information, and customer information; and a control unit 270 that predicts how the liquid will increase based on the history of the liquid amount.

[0064] The server 200 may be composed of multiple servers, or may be a cloud server.

[0065] The communication unit 210 can communicate with the detection device 100 located on the user's side, a first terminal 300 for editing and displaying information in the server 200, a second terminal 400 for displaying the amount of liquid detected by the detection device 100, and a third terminal 500 carried by the collection officer for displaying information in the server 200.

[0066] The communication by the communication unit 210 may be either wireless or wired.

[0067] The mapping unit 220 arranges the liquid amount information received from each of the multiple detection devices 100 on a map 221 .

[0068] The liquid amount information received from the detection device 100 is stored in the server storage unit 260.

[0069] Furthermore, map information of the map 221 displayed by the mapping unit 220 on the first terminal 300 and the third terminal 500 is stored in the server storage unit 260 .

[0070] FIG. 2 shows display screens displayed on first display unit 310 and third display unit 510 of first terminal 300 and third terminal 500. As shown in FIG.

[0071] On the display screen shown in FIG. 2, liquid amount information is displayed on a map 221 by a mapping unit 220.

[0072] In this embodiment, the amount of liquid is expressed as a percentage or a number of liters corresponding to the percentage, and the location of each detection device 100 is located on the map 221.

[0073] The map 221 can be enlarged and reduced, and can also be changed to an aerial photograph as shown in FIG.

[0074] By showing the position (location) of the detection device 100, i.e., the position (location) of the liquid container 110 on the map 221, and also the amount of liquid in the container 110, the user of the first terminal 300 and the user of the third terminal 500 (collection staff) can intuitively confirm where they should give priority to collecting the liquid.

[0075] The calendar unit 230 displays the information on the amount of liquid received from the detection device 100 on a calendar displayed on the first terminal 300 and the third terminal 500.

[0076] The calendar unit 230 includes an amount prediction calendar 231 that displays the amount of liquid on a calendar displayed on the first terminal 300 and the third terminal 500; and a collection schedule 232 for identifying the liquid collection schedule.

[0077] On the display screen shown in FIG. 2, a quantity forecast calendar 231 and a collection schedule 232 are displayed.

[0078] 4 shows the display screen when the quantity forecast calendar 231 is selected, which is the "month" screen. Note that the screen can also be changed to the "week" screen.

[0079] In the quantity forecast calendar 231, as customer information 231a, 231b, and 231c, customer information 231a with high urgency is displayed in red, customer information 231b with the next highest urgency is displayed in yellow, and normal customer information 231c is displayed in blue.

[0080] For example, from the past amount of liquid (excrement) in the temporary toilet (changes in the amount of liquid in the past) and the capacity of the container 110, the control unit 270 calculates (predicts) an estimated date when the amount of liquid will reach the maximum allowable amount of the container 110.

[0081] Specifically, the control unit 270 predicts the number of days remaining until the liquid reaches the maximum allowable amount of the container 110, and determines the estimated day on which the liquid will reach the maximum allowable amount from the number of days remaining.

[0082] More specifically, the control unit 270 obtains the average amount of liquid per day by dividing the sum of the amounts of liquid detected in the past by the corresponding number of days, and calculates the number of days remaining until the liquid reaches the maximum allowable amount by dividing the difference between the total capacity of the container 110 and the amount of liquid in the container 110 by the average value.

[0083] For example, the control unit 270 divides the sum of the amounts of liquid detected over 90 days by the number of days, 90, to obtain the average amount of liquid per day.

[0084] That is, if the amount of liquid in container 110 is 1800L, control unit 270 divides 1800L by 90 days to find that the average amount of liquid per day is 20L.

[0085] If the maximum allowable volume of container 110 is 1000 L and the amount of liquid in container 110 is 800 L, control unit 270 will calculate the remaining number of days as 10, obtained by subtracting 800 L from 1000 L (200 L) and dividing the difference by the average value of 20 L (20 L).

[0086] The calendar section 230 displays customer information 231 a , 231 b , and 231 c on the amount prediction calendar 231 on the day when the control section 270 predicts that the liquid will reach the maximum allowable amount of the container 110 .

[0087] The calendar section 230 sets two thresholds according to the amount of liquid in each temporary toilet, and displays customer information on the amount prediction calendar 231 in blue (231c), yellow (231b), or red (231a) according to the thresholds.

[0088] Specifically, customer information is normally displayed in blue (231c) on the quantity prediction calendar 231, but when the amount of liquid detected by the detection device 100 is increasing (when it falls below the first threshold), it is displayed in yellow (231b), and when the amount of liquid detected by the detection device 100 is approaching the maximum allowable amount (when it falls below the second threshold), it is displayed in red (231a).

[0089] The threshold value can be set for each group, and in this embodiment, when the amount of liquid is equal to or less than the first threshold value, the color changes from blue to yellow, and when the amount of liquid is equal to or less than the second threshold value, the color changes from yellow to red, but the color can be any color as long as it can be distinguished. The threshold value may be set arbitrarily according to each temporary toilet.

[0090] In the quantity prediction calendar 231, "location of liquid", "type of liquid", and "amount of liquid" are displayed as customer information 231a, 231b, and 231c.

[0091] The quantity prediction calendar 231 displays customer information 231a, 231b, and 231c on the day before the liquid is predicted to run out of the container 110.

[0092] For example, the amount of liquid is displayed as a percentage of the amount of liquid and as the amount divided by the total tank capacity (L), such as "7% 19.04 / 272L."

[0093] The customer information 231a (231b, 231c) displayed in FIG. 5 and FIG. 6 is a display screen when the customer information 231a (231b, 231c) displayed on the quantity forecast calendar 231 shown in FIG. 4 is selected.

[0094] Fig. 5 is an example of a temporary toilet, and the liquid is waste such as feces and urine. And Fig. 6 is an example of the liquid being waste cooking oil.

[0095] The customer information 231a (231b, 231c) is stored in the server memory unit 260, and for example, as shown in Figures 5 and 6, the customer information 231a (231b, 231c) includes the customer name, address, location of the container 110, type of liquid, type of container 110, amount used, tank capacity, status, signal level, remaining days, last collection date, serial number, temperature, amount of liquid, and estimated value.

[0096] As shown in Figures 5 and 6, the amount and estimate of liquid (waste) is displayed in a graph.

[0097] For example, the customer information 231a (231b, 231c) shown in Figure 5 shows that the remaining days are 1 day (October 21, 2021), and this customer information 231a (231b, 231c) is displayed on the quantity forecast calendar 231 for October 21st.

[0098] Also, for example, the customer information 231a (231b, 231c) shown in Figure 6 shows that the remaining days are 1 day (October 21, 2021), and this customer information 231a (231b, 231c) is displayed on the quantity forecast calendar 231 for October 21st.

[0099] The liquid volume graph can be changed to display 1 week, 1 month, 3 months, 6 months, 12 months, etc.

[0100] Additionally, the liquid amount graph displays an estimate, which is a prediction of the liquid amount based on past graph changes.

[0101] The estimated value in this embodiment is the quotient obtained by dividing the sum of the past amounts by the number of days up to that point (converted into hours), and is the average amount per day.

[0102] The amount of liquid is predicted by the control unit 270 from past changes in the amount of liquid (how it has increased) and the capacity of the container 110. Specific details will be described later.

[0103] When a schedule list 231d displayed on the quantity prediction calendar 231 is selected, a list of "Installation location," "Type of liquid," and "Amount of liquid" displayed on the calendar is displayed.

[0104] Collection schedule 232 allows the liquid collection schedule to be confirmed, and is used by collection personnel to check their own collection schedules and by managers to check collection status, with the installation locations being displayed on a calendar.

[0105] The alert unit 240 displays, among the multiple containers 110 on the map 221, the number of containers 110 in which the amount of liquid has increased and the number of containers 110 in which the amount of liquid has reached the maximum allowable amount.

[0106] Furthermore, the alert unit 240 issues warning information about the amount of liquid, and warns of malfunctions in the detection device 100 (for example, mechanical malfunctions of the sensor, malfunctions such as misalignment, etc.).

[0107] The alert unit 240 includes an alert display unit 241 that warns of the liquid status, and an alert 242 that displays the specific content of the alert.

[0108] On the display screen shown in FIG. 2, an alert display section 241 and an alert 242 are displayed by an alert section 240.

[0109] The alert display unit 241 allows the user to check the number of containers 110 in which the amount of liquid has increased and the number of containers 110 in which the amount of liquid has reached the maximum allowable amount.

[0110] When the Alert 242 page is opened, "Volume Warning," "Sensor Alert," and "Past Warnings" are displayed on the screen, along with a list of "Warnings" such as the "Installation Location" of the container 110 with the company name displayed, the "Type" indicating the liquid volume status, and "The recovery level of XX is currently 21 and has exceeded the set threshold of 70% since 2021 / 10 / 4 0:32:44."

[0111] The customer information management unit 250 includes a customer 251 that displays customer information, and a person in charge 252 that displays the person in charge of the customer.

[0112] Customer information is managed in the customer information management unit 250. Specifically, customer names, postal codes, addresses, telephone numbers, persons in charge, email addresses of persons in charge, and mobile phone numbers are stored in the server storage unit 260, and the customer information management unit 250 manages the information.

[0113] Customer 251 displays customer information, including the customer's name, postal code, address, telephone number, and person in charge.

[0114] The person in charge 252 displays the person in charge of the customer and an email address. The person in charge 252 may also display the mobile phone number of the person in charge of the customer.

[0115] The server storage unit 260 stores the liquid amount information from each of the detection devices 100 .

[0116] Furthermore, the server storage unit 260 stores customer information, map information, list information, and alert information.

[0117] The server memory unit 260 stores, for example, a reference amount (numerical value) for determining quantity information, the capacity of the container 110 installed at each installation location, the standard increase in the amount of liquid at each installation location, the date and time when the liquid was last collected at each installation location, and the address of each installation location.

[0118] The customer information is the same as the customer information 231a. The map information is the map information of the map 221 displayed on the first terminal 300 and the third terminal 500.

[0119] List information is information in which information displayed on the quantity forecast calendar 231 is displayed in a list.

[0120] The alert information is information displayed on the alert unit 240, and is information that is displayed when the liquid exceeds a threshold value, information that is displayed when an abnormality occurs in the detection device 100, and the like.

[0121] For example, if a mechanical malfunction occurs in the liquid level sensor 120, or if the sensor is placed at an angle for some reason, this is displayed and stored as alert information.

[0122] The control unit 270 predicts how the liquid will increase in the container 110 from the transition of the liquid amount information stored in the server storage unit 260.

[0123] Specifically, the control unit 270 calculates the average hourly amount change of the liquid in the container 110 stored in the server storage unit 260 up to now.

[0124] More specifically, the control unit 270 predicts the number of days remaining until the liquid reaches the maximum allowable amount of the container 110, and determines the estimated date on which the liquid will reach the maximum allowable amount from the number of days remaining.

[0125] The number of days remaining until the liquid reaches the maximum allowable amount is calculated and determined by the control unit 270 as described above.

[0126] The control unit 270 may also calculate the average hourly change in the amount of liquid in the container 110 thus far, as stored in the server memory unit 260, and calculate an estimated day on which the liquid in the container 110 will reach the maximum allowable amount.

[0127] The estimated date when the liquid will reach maximum allowable volume is displayed on volume forecast calendar 231.

[0128] The server 200 may store quantity information, current location information of the delivery vehicle, and the like via an electrical communication circuit.

[0129] The liquid recovery system 10 of the present embodiment is capable of recovering liquid in units of, for example, 1 liter.

[0130] That is, in this embodiment, collection can be performed before the container 110 reaches its maximum allowable amount.

[0131] For example, the control unit 270 can set collection groups based on the installation location information (customer information 231a, 231b, 231c) stored in the server storage unit 260 as follows.

[0132] Installation location information refers to customer information 231a, 231b, and 231c, such as the address of the temporary toilet (installation location), information on the amount of liquid in each temporary toilet, the tank capacity of container 110 for each temporary toilet (installation location), and the liquid amount history for each temporary toilet (installation location).

[0133] The liquid amount history is a record of the past amounts of liquid, as shown in FIGS.

[0134] A collection group can be set, for example, based on the address of the temporary toilet (installation location) to include temporary toilets (installation locations) located in the vicinity or in the same direction as the collection source (the location of the collection company).

[0135] For example, if a recovery company (a user of the liquid recovery system 10 in this embodiment) is located in Kyoto Prefecture, collection locations in Shiga Prefecture and Fukui Prefecture can be set as the same collection group, and collection locations in Osaka Prefecture and Hyogo Prefecture can be set as the same collection group.

[0136] Furthermore, if the location of the recovery company (the user of the liquid recovery system 10 in this embodiment) is in Kyoto City, the collection location in Uji City, Kyoto Prefecture and the collection location in Joyo City, Kyoto Prefecture (both located south of the location of the recovery company in Kyoto City) can be set as the same collection group, and the collection location in Maizuru City, Kyoto Prefecture and the collection location in Fukuchiyama City, Kyoto Prefecture (both located north of the location of the recovery company in Kyoto City) can be set as the same collection group.

[0137] The collection group is set so that customer information 231a with high urgency displayed on the quantity forecast calendar 231 is preferentially included.

[0138] The collection group may be set by a person in charge of the collection company, or the control unit 270 may set the collection group.

[0139] Furthermore, in this embodiment, the liquid is excrement such as feces and urine and waste edible oil, but it may be waste oil, waste liquid, sewage, or sludge.

[0140] The present invention can be implemented in various forms with improvements, modifications, or variations without departing from the spirit of the invention. [Explanation of symbols]
