Abstract
Description
Technical Field
[0001] This utility model belongs to the field of socket technology, specifically relating to a safe power protection socket based on big data detection. Background Technology
[0002] According to statistics, approximately 90,000 fires caused by electrical outlets occur in my country each year, with outlet use accounting for a significant proportion of these incidents. Furthermore, fires caused by outlets are not only numerous but also have severe consequences. Statistics show that about 8,000 people die from electric shock each year, with 30% of these deaths related to electrical outlets. Therefore, every technical detail related to outlet safety deserves in-depth investigation and improvement.
[0003] 1. A search revealed that the patent titled "An Inductive LED Power Strip" (patent number 202120567727.3) has the following defects:
[0004] (1) The patent describes that when the sensor detects a person's arrival, the LED indicator light is turned on in the dark or at night. There is a defect here: it does not specifically quantify what constitutes "darkness" or what period of time is considered "night". For example, according to the "Noise Pollution Prevention and Control Law of the People's Republic of China", "night" refers to the period between 10 p.m. and 6 a.m. If this regulation is followed, it means that the patent technology cannot be implemented before 10 p.m. However, lights may be on at night, and the environment may be dim during the day. Therefore, the patent does not specify the prerequisite of being at night or in dim light.
[0005] (2) The patent only states that when the sensor detects a person's arrival, the controller can control the indicator light to be turned on, but it does not specify how the indicator light should change after it is turned on, whether it should remain on throughout the night, during use, or only for a period of time. Moreover, the conditions for the indicator light to turn off are not given, and no technical details are provided.
[0006] (3) This patent is a power strip. The biggest feature of the power strip is that it is a movable socket, which means that it may not be easy to find its location in the dark or at night. Therefore, it is not convenient for users to quickly and accurately locate the socket.
[0007] 2. The patent title is: "A Self-Induction Safety Socket (202122205121.8)". A self-induction control system is installed inside the socket body. This system is signal-connected to all female socket connectors forming the plug hole. When a male plug is inserted into each female socket connector, the self-induction control system energizes the female socket connector, thus greatly preventing electric shock accidents and ensuring electrical safety. However, in real life, there are many items similar to women's hair clips with two prongs, and there is a possibility that a child could insert both plugs simultaneously.
[0008] 3. Traditional sockets, such as the authorized patent "A highly protective safety power strip (202023322704.0)," use baffles to seal the socket holes to ensure electrical safety. Although this method can prevent children from inserting foreign objects and getting electric shocks, the baffle is a mechanical structure. On the one hand, it will be damaged by long-term contact with the plug during use. On the other hand, because the baffle seals the socket hole, a lot of force is needed to insert the plug, which is not very convenient to use.
[0009] 4. The patent title is: "A New Type of Household Socket" (201620226769.X). This patent solution mainly addresses the safety issues of children accidentally touching the socket and getting electric shocks, and the need to disconnect the power when not using the socket. See attached instruction manual. Figure 7 After careful reading, the following defects and deficiencies were found in the patent (refer to paragraph 15 of the original specification):
[0010] (1) When the protective cover is opened, the displacement sensor is triggered and sends a protective cover opening signal to the microprocessor. After receiving the protective cover opening signal, the microprocessor controls the coil of the first relay KM1 to be energized through the control circuit of the first relay KM1, and the normally open contact of the first relay KM1 closes, and the main circuit of the socket is in a connected state. This design has a logical problem. When the protective cover is not opened, it can protect children from electric shock regardless of whether the socket is energized. On the contrary, when the protective cover is opened, the socket circuit is energized, which may cause children to be electrocuted.
[0011] (2) When the current sensor BA detects the current, the normally closed contact of the second relay KM2 is closed. However, when the household appliance is not in use and the power is off, the current sensor BA cannot detect the current. At this time, the microprocessor controls the normally closed contact of the second relay KM2 to open, thus disconnecting the main circuit of the socket. Because the current sensor BA detects the current flowing through the circuit after the normally closed contact KM2 of the second relay, it means that once the normally closed contact KM2 opens for the first time, the current detected by the current sensor BA will always be zero, meaning that the normally closed contact KM2 will never close again, thus creating a dead loop. Obviously, such a design is illogical and cannot achieve its purpose.
[0012] (3) As can be seen from the figure, the technical solution involves multiple different types of sockets connected in parallel. The normally open contact of the first relay KM1 and the normally closed contact of the second relay KM2 are connected in series at the front end of all the parallel sockets. That is, when the protective cover is opened, as long as one socket is plugged into an electrical appliance, the other sockets will be energized regardless of whether an electrical appliance plug is plugged into them. Therefore, there is still a safety hazard.
[0013] Based on the above search and analysis, the inventor team, after discussion and research, proposed a safe power protection socket based on big data detection. Utility Model Content

The other end of the spring is connected to the back of the cover plate. The cover plate has a hole in the middle of the two-hole socket hole and the three-hole socket hole. A part of the conductive post protrudes outward from the hole.
[0021] It also includes pressure sensor three and pressure sensor four corresponding to the transmission column. The microcontroller is connected to the relays corresponding to pressure sensor three, pressure sensor four, normally open switch KF3, and normally open switch KF4 for communication data.
[0022] Furthermore, it also includes an indicator light L11 installed at the live wire copper contact CU11, an indicator light L12 installed at the neutral wire copper contact CU12, an indicator light L21 installed at the live wire copper contact CU21, an indicator light L22 installed at the neutral wire copper contact CU22, and an indicator light L23 installed at the ground wire copper contact CU23.
[0023] Indicator lights L11 and L12 are connected in series, as are indicator lights L21, L22, and L23. The upper terminals of indicator lights L11 and L21 are connected in parallel and then connected to the lower terminal of normally open switch KC1. Normally open switch KC1 is connected in series with voltage divider FY2. The upper terminal of voltage divider FY2 is connected to the lower terminal of normally open self-resetting switch SB11. The lower terminals of indicator lights L12 and L23 are both connected to the power supply neutral wire.
[0024] It also includes a light sensor, with a transparent window on the cover plate, and the light sensor is located on the back of the transparent window; the microcontroller communicates and connects with the light sensor and the relay of the normally open switch KC1.
[0025] Furthermore, it also includes a time-delay normally open switch KT1, the upper port of which is connected to the lower port of a normally open switch KC1, and the upper ports of indicator lights L11 and L21 are connected in parallel to the lower port of the time-delay normally open switch KT1.
[0026] It also includes a human body sensor. The cover plate has mesh holes, and the human body sensor is set in the mesh holes. The microcontroller communicates and connects with the human body sensor and the relay of the time-delay normally open switch KT1.
[0027] Furthermore, it also includes a normally closed switch KF12 interlocked with the normally open switch KF11 and a normally closed switch KF22 interlocked with the normally open switch KF21; the upper ports of normally closed switches KF12 and KF22 are connected in parallel and then connected to the lower port of the time-delay normally open switch KT1; the lower port of normally closed switch KF12 is connected to the upper port of indicator light L11; and the lower port of normally closed switch KF22 is connected to the upper port of indicator light L21.
[0028] Furthermore, it also includes a self-resetting normally closed switch SB12 interlocked with the self-resetting normally open switch SB11 and a voltage divider FY3. The upper port of the self-resetting normally closed switch SB12 is connected to the upper port of the self-resetting normally open switch SB11, the lower port of the self-resetting normally closed switch SB12 is connected to the upper port of the voltage divider FY3, and the lower port of the voltage divider FY3 is connected to the lower port of the time-delay normally open switch KT1.
[0029] Furthermore, the back of the cover plate has a protrusion. When the base is fastened to the cover plate, the self-resetting normally open switch SB11 will be closed by the protrusion.
[0030] Furthermore, it also includes a WiFi module, which connects to the microcontroller for data communication and to the mobile phone for wireless communication.
[0031] Compared with the prior art, the present invention has the following beneficial effects:
[0032] 1. This utility model features a protrusion on the back of the cover plate. When the base and cover plate are fastened together, the self-resetting normally open switch SB11 is closed by the protrusion. The self-resetting normally open switch SB11 is the master switch for the entire socket; that is, as long as the cover plate is opened and the self-resetting normally open switch SB11 is sufficiently concealed, there is no risk of electric shock. Conversely, only when the cover plate and base are installed together will the live wire copper contacts of the socket have the opportunity to receive electricity. Simultaneously, the self-resetting normally closed switch SB12 is interlocked with the self-resetting normally open switch SB11. The self-resetting normally closed switch SB12 is connected to the indicator lights. When the cover plate is opened, the self-resetting normally closed switch SB12 will conduct, causing all indicator lights to illuminate, thus alerting the user that the socket is connected to power and requiring careful use.
[0033] 2. This utility model includes pressure sensors 1 and 2 installed at the neutral copper contact CU12 and CU22, respectively. The normally open switches KF11 and KF21 of the corresponding circuits will only close and conduct when pressure sensors 1 and 2 receive pressure, thus improving safety. Furthermore, since pressure sensors 1 and 2 are installed at the neutral copper contact CU12 and CU22, there is no risk of electric shock when only one socket is inserted. To further enhance safety, normally open switches KF3 and KF4 are also included, along with pressure sensors 3 and 4. Pressure sensors 3 and 4 are located in the middle holes of the two-hole and three-hole bases, respectively. This means that normally open switches KF3 and KF4 will only close and conduct when the appliance plug is tightly against the cover, preventing the plug's copper contacts from being partially exposed and posing a risk of electric shock. Together with normally open switches KF11 and KF21, they form a double safety net, completely avoiding electric shock accidents caused by accidental contact or insertion of foreign objects, as is the case with traditional technologies.
[0034] 3. This utility model includes a first current sensor installed at the lower end of a normally open switch KF11 and a second current sensor installed at the lower end of a normally open switch KF21. Normally open switches KF11 and KF12 are interlocked, as are normally open switches KF21 and KF22. A voltage divider FY1 is connected in series with the upper ends of normally closed switches KF12 and KF22 connected in parallel. When the first and second current sensors detect zero current, normally closed switches KF12 and KF22 close, and normally open switches KF11 and KF21 open. Because of the voltage divider, the live wire copper contact of the corresponding socket receives only a reduced voltage. This protects electrical plugs that are plugged in for extended periods without being used, solving the problem of short circuits or fires caused by overheating in traditional plugs.
[0035] 4. This utility model also includes a light sensor and a normally open switch KC1. The normally open switch KC1 will only close when the ambient light intensity is less than the threshold. In addition, it also includes a human body induction sensor and a delayed normally open switch KT1. That is, the delayed normally open switch KT1 will only close when a person (hand) is sensed approaching. When both of the above conditions are met at the same time, all indicator lights will be lit, so that the user can quickly locate the socket position and ensure the safety of the person when the plug is inserted.
[0036] 5. This utility model addresses several aspects, including socket structure, lighting, energy saving, voltage, and current, to comprehensively design a socket with multiple safety features. It can greatly ensure the safety of the socket and personnel, and has strong market application prospects. Attached Figure Description

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0047] The data to be detected by this utility model includes pressure data, current magnitude, light intensity, human body temperature data, or distance data from the socket, which are detected by corresponding sensors. The actuator is mainly a relay (switch).
[0048] Example 1
[0049] Reference Appendix Figures 1-6This utility model is a safety power protection socket based on big data detection. It includes a base and a cover plate 1. The cover plate has two socket holes 21 and three socket holes 22. The base includes a two-hole base and a three-hole base. The two-hole base is equipped with a live wire copper contact CU11 and a neutral wire copper contact CU12. The three-hole base is equipped with a live wire copper contact CU21, a neutral wire copper contact CU22 and a ground wire copper contact CU23.
[0050] The live wire copper contact CU11 is connected to the lower terminal of normally open switch KF11. The lower terminals of normally open switch KA11 and normally closed switch KA12 are connected in parallel to the upper terminal of normally open switch KF11. The live wire copper contact CU21 is connected to the lower terminal of normally open switch KF21. The lower terminals of normally open switch KA21 and normally closed switch KA22 are connected in parallel to the upper terminal of normally open switch KF21. The normally closed switch KA12 is connected in parallel to the upper terminal of normally closed switch KA22 and then connected to the lower terminal of voltage divider FY1. The upper terminals of normally open switch KA11, voltage divider FY1, and normally closed switch KA22 are connected in parallel to the lower terminal of normally open self-resetting switch SB11. The upper terminal of self-resetting normally open switch SB11 is connected to the live wire. The neutral wire copper contact CU12 and neutral wire copper contact CU22 are connected in parallel to the neutral wire. The ground wire copper contact CU23 is connected to the ground wire. All switches except normally open self-resetting switch SB11 are switches for the respective relays. The function of voltage divider FY1 is to reduce the voltage of the live wire copper contact CU11 and live wire copper contact CU21, so as to protect the appliance from overheating and causing a fire even if the plug is fully inserted into the socket when it is not in use. On the other hand, when the appliance is in use, a small current will flow through it.
[0051] It also includes a microcontroller, pressure sensor one installed at the neutral wire copper contact CU12, and pressure sensor two installed at the neutral wire copper contact CU22. The advantage of this installation is that even if a foreign object is inserted into the live wire copper contact CU11 or CU21, because pressure sensor one and pressure sensor two do not detect pressure, normally open switches KF11 and KF21 will not close, and the live wire copper contacts CU11 and CU21 will not be energized, thus preventing electric shock. Furthermore, even if a foreign object is inserted into the neutral wire copper contact CU12... Although pressure sensors 1 and 2 can detect pressure at the copper contact CU22, and normally open switches KF11 and KF21 will close, the voltage at the neutral copper contact CU12 and CU22 is zero, so electric shock will not occur. This ingenious design ensures that the live wire copper contact CU11 and CU21 will not be energized when no plug is inserted, and also ensures that inserting any foreign object into any single socket will not energize the live wire copper contact CU11 and CU21, thus guaranteeing the safety of the socket. This includes current sensor 1 installed at the lower end of normally open switch KF11 and current sensor 2 installed at the lower end of normally open switch KF21; the microcontroller communicates with each sensor and relay.
[0052] The back of the cover has a protrusion. When the base is secured to the cover, the self-resetting normally open switch SB11 will be closed by the protrusion. The self-resetting normally open switch SB11 is the main switch for the entire socket. When the cover is open, the exposed connectors pose a higher risk of electric shock. Therefore, this design prevents users from using the socket while the cover is open, thus avoiding the danger. Conversely, the socket will only conduct power when the cover is closed, improving safety. The self-resetting normally open switch SB11 can be designed in a concealed location.
[0053] A better technical solution also includes normally open switches KF3 and KF4 of the relay, normally open switches KA11 and KA12 connected in parallel at their lower ends and then connected to the upper end of normally open switch KF3, and normally open switch KF3 connected in parallel at its lower end and normally open switch KF11 at its upper end; normally open switches KA21 and KA22 connected in parallel at their lower ends and then connected to the upper end of normally open switch KF4, and normally open switch KF4 connected in parallel at its lower end and normally open switch KF21 at its upper end.
[0054] Further, see attached document. Figure 6 It also includes a self-reset button, which includes a transmission post 5 and a spring. One end of the transmission post passes through the spring and is connected to the bottom of the spring. The other end of the spring is connected to the back of the cover plate. The cover plate has a hole 11 in the middle of the two-hole socket hole and the three-hole socket hole. A part of the transmission post protrudes outward from the hole.
[0055] It also includes pressure sensors three and four corresponding to the conduction column. The microcontroller is connected to the relays corresponding to pressure sensors three and four, as well as normally open switches KF3 and KF4. When an object presses on the outer end of the conduction column, the spring is stretched until the inner end of the conduction column can contact pressure sensors three and four, generating a pressure signal.
[0056] The above technical solution emphasizes that the live wire copper contacts CU11 and CU21 are only energized when the socket is inserted or firmly plugged in. This technical solution has two beneficial effects: Firstly, it adds pressure sensors three and four, meaning that normally open switches KF11, KF3, KF12, and KF4 will only close and conduct when pressure sensors one and three, or two and four, detect pressure simultaneously, thus increasing the safety protection level. Secondly, it ensures that the plug is only energized when it is securely fastened, preventing the copper contacts from being partially exposed and increasing the risk of electric shock or short circuit.
[0057] The improved technical solution also includes an indicator light L11 installed at the live wire copper contact CU11, an indicator light L12 installed at the neutral wire copper contact CU12, an indicator light L21 installed at the live wire copper contact CU21, an indicator light L22 installed at the neutral wire copper contact CU22, and an indicator light L23 installed at the ground wire copper contact CU23.
[0058] Indicator lights L11 and L12 are connected in series, as are indicator lights L21, L22, and L23. The upper terminals of indicator lights L11 and L21 are connected in parallel and then connected to the lower terminal of normally open switch KC1. Normally open switch KC1 is connected in series with voltage divider FY2. The upper terminal of voltage divider FY2 is connected to the lower terminal of normally open self-resetting switch SB11. The lower terminals of indicator lights L12 and L23 are both connected to the power supply neutral wire.
[0059] It also includes a light sensor, and the cover plate has a transparent window 3. The light sensor is set on the back of the transparent window; the microcontroller communicates with the light sensor and the relay of the normally open switch KC1.
[0060] Furthermore, it also includes a time-delay normally open switch KT1, the upper port of which is connected to the lower port of a normally open switch KC1, and the upper ports of indicator lights L11 and L21 are connected in parallel to the lower port of the time-delay normally open switch KT1.
[0061] It also includes a human body sensor, which can be selected from infrared sensors or ultrasonic sensors according to actual needs. It is mainly for short-range sensing, such as sensing the palm of the hand. The cover plate has mesh holes 4, and the human body sensor is set in the mesh holes. The microcontroller communicates with the human body sensor and the relay of the time-delay normally open switch KT1.
[0062] Furthermore, it also includes a normally closed switch KF12 interlocked with the normally open switch KF11 and a normally closed switch KF22 interlocked with the normally open switch KF21; the upper ports of normally closed switches KF12 and KF22 are connected in parallel and then connected to the lower port of the time-delay normally open switch KT1; the lower port of normally closed switch KF12 is connected to the upper port of indicator light L11; and the lower port of normally closed switch KF22 is connected to the upper port of indicator light L21.
[0063] A better technical solution also includes a self-resetting normally closed switch SB12 and a voltage divider FY3 interlocked with the self-resetting normally open switch SB11. The upper port of the self-resetting normally closed switch SB12 is connected to the upper port of the self-resetting normally open switch SB11, the lower port of the self-resetting normally closed switch SB12 is connected to the upper port of the voltage divider FY3, and the lower port of the voltage divider FY3 is connected to the lower port of the time-delay normally open switch KT1.
[0064] A further improved technical solution includes a WiFi module, which communicates with the microcontroller via data and wirelessly with the mobile phone. The WiFi module can send relevant data about the socket to the mobile phone, and the mobile app can monitor and statistically analyze the large amount of operational data generated during the socket's use.
[0065] Example 2
[0066] Reference Appendix Figures 1-6 Based on Example 1, the safe power-on control method for residential sockets includes five levels of safety protection; wherein, the power-on control method for the first-level safety protection is as follows:
[0067] When the cover plate is tightly closed to the base, the protrusion on the back of the cover plate presses against the self-resetting normally open switch SB11, causing it to close and become energized. Conversely, when the cover plate is separated from the base, the protrusion no longer contacts the self-resetting normally open switch SB11, so the self-resetting normally open switch SB11 is in the open state and de-energized.
[0068] The power-on control method for secondary safety protection is as follows:
[0069] When the plug is inserted into the two-hole base or / and the three-hole base, after the corresponding pressure sensor 1 and pressure sensor 2 detect the pressure, the pressure signal is sent to the microcontroller. After the microcontroller performs the calculation, it sends a signal to the relay, which executes the closing of the corresponding normally open switch KF11 and normally open switch KF21 to energize.
[0070] And / or, when the corresponding pressure sensor three and pressure sensor four detect pressure, the pressure signal is sent to the microcontroller. After the microcontroller performs the calculation, it sends a signal to the relay to close the corresponding normally open switch KF3 and normally open switch KF4 to energize.
[0071] Conversely, when the plug is unplugged from the two-hole base or / and the three-hole base, if the pressure sensor 1, pressure sensor 2, pressure sensor 3, and pressure sensor 4 cannot detect pressure, the corresponding normally open switches KF11, KF21, KF3, and KF4 will all be disconnected.
[0072] The power-on control method for Level 3 safety protection is as follows:
[0073] When the plug is inserted into the two-hole base or / and the three-hole base, if the corresponding current sensor one and current sensor two detect that the current is zero, the microcontroller sends a signal to the relay, and the corresponding normally closed switch KA11 opens and normally open switch KA12 closes, normally closed switch KA21 opens and normally open switch KA22 closes.
[0074] If the current sensor 1 and current sensor 2 detect a current greater than zero, the microcontroller sends a signal to the relay, which closes the normally closed switch KA11 and opens the normally open switch KA12, and closes the normally closed switch KA21 and opens the normally open switch KA22.
[0075] Furthermore, when normally open switches KA12 and KA22 are closed, the voltage at the live wire copper contact CU11 and CU21 can be set to any value greater than zero and less than 36V.
[0076] The above technical solution addresses two scenarios when an appliance is plugged into a socket: either the appliance is using power or it is not (e.g., a fan is off, or a phone charger is not connected). When the appliance is using power, the voltage at the live wire copper contacts CU11 and CU21 is 220V, which is normal. However, if the appliance is not using power but the plug remains plugged in, it may cause the plug to overheat, or the plug may age or have quality issues, leading to a short circuit or even a fire. Case studies show that most socket fires are caused by this. Therefore, this technical solution reduces the voltage at the live wire copper contacts CU11 and CU21 to a safe level below 36V via voltage divider FY1 when the current sensors 1 and 2 detect zero current. This ensures personnel safety and prevents the plug from overheating or short-circuiting and causing a fire due to prolonged unused use.
[0077] Furthermore, the power-on control method for the fourth-level safety protection is as follows:
[0078] Assuming the threshold illuminance at which the human eye cannot clearly see objects in the surrounding environment is: E0 Its unit is Lux; then when the light sensor detects that the ambient illuminance is less than... E0 When the signal is greater than or equal to the specified value, the microcontroller sends a signal to the corresponding relay, and the normally open switch KC1 closes to conduct. E0When the normally open switch KC1 is in the open state, all indicator lights will not be lit when a person can clearly see the surrounding objects.
[0079] Furthermore, when the human body sensor detects a person, the microcontroller sends a signal to the corresponding relay, causing the normally open delay switch KT1 to close and conduct. At this time, indicator lights L11, L12, L21, L22, and L23 all illuminate. The delay time can be set to 3-5 seconds, meaning the normally open delay switch KT1 will automatically disconnect 3-5 seconds after closing. In other words, when someone (hand) approaches, all indicator lights briefly illuminate to facilitate accurate plugging in in dim or dark environments, improving plugging efficiency and safety. To avoid disturbing sleep or for energy saving, the lights automatically disconnect after 3-5 seconds, especially between 11 PM and 6 AM, during which time all indicator lights will turn off.
[0080] Furthermore, when the plug is inserted into the two-hole socket or / and three-hole socket, normally closed switches KF12 and KF22 will open after the corresponding pressure sensor 1 and pressure sensor 2 detect pressure, causing the corresponding indicator light to turn off. That is, when the socket is occupied or in use, the indicator light corresponding to the socket will no longer be lit.
[0081] Furthermore, the clock switch T1 can be set to close between 6:00 AM and 10:00 PM. During this period, as long as the illuminance is less than the threshold... E0 All indicator lights will remain constantly lit to remind and guide users of the location of the socket, unless the plug is inserted, at which point normally closed switches KF12 and KF22 will open and the corresponding indicator lights will turn off; that is, the disconnection time is from 11 pm to 6 am. During this period, the indicator lights should not be constantly lit to avoid disturbing people's rest, especially for sockets installed in bedrooms. The microcontroller sends a time signal to the corresponding relay, and the clock switch T1 operates according to the corresponding time period.
[0082] The power-on control method for Level 5 safety protection is as follows:
[0083] When the cover plate is separated from the base, the self-resetting normally closed switch SB12 closes and conducts, at which time all indicator lights are lit to warn that the socket is energized, reminding personnel that the socket is in a dangerous operating state; conversely, when the cover plate is tightly closed to the base, the self-resetting normally closed switch SB12 opens.
[0084] The specific number of relays used in this invention varies depending on the number of switching contacts selected. Furthermore, depending on the size of the socket's mechanical structure and the requirements of the circuit design, some relays may also be electronic switches. Other electronic components not mentioned in this invention but related to it are all within the scope of understanding and implementation by those skilled in the art.
