Description

The invention relates to a method and system by means of which a user interface for displaying a device status of a device can be operated. The display shows a user of the device a residual value or sales value of the device as the device status, so that the user is shown the wear and tear of the motor vehicle in a way that reflects the replacement value or the residual proceeds, because an old device does not necessarily have to be worthless. A collector's item or a rarity shows a high level of wear and tear, but can still achieve high proceeds in relation to its selling price. This only becomes visible through the conversion of condition data into a sales price. The invention also includes the components of the system, namely a server device and at least one device to be evaluated. The device can be, for example, a motor vehicle or a mobile terminal device or a computer.

In the case of a motor vehicle, it is even very complex to even determine an estimated value for a sales price. If a user of a motor vehicle is interested in selling it, he must first individually check the wear and tear of the many different components of the motor vehicle. Showing this on a sales price or summarizing it into a sales price requires a lot of estimation effort and comparisons with motor vehicles whose device components were in a similar state of wear. If a user then decides against the sale but would like to start the sales procedure again later, the entire estimation process must be repeated since the condition of the motor vehicle has changed. This makes selling a motor vehicle undesirably burdensome.

From the US 2018/0025391 A1 It is known that the states of individual vehicle components can be detected by control units of a motor vehicle and a display can be generated from this by a server for information about recommended repair or maintenance. The server can also communicate the determined state of wear to a dealer, who can then send the user an offer to buy the motor vehicle. However, the dealer must estimate the selling price based on his experience.

From the DE 10 2008 005 465 A1 a method for sales support for the sale of a used car is known. A user can enter status data of the motor vehicle on a first computer, which is then sent to a second computer, where a sales price is determined. The second computer can adjust the sales price by subtracting repair costs from vehicle components that require repairs in order to anticipate an impending repair of the motor vehicle. The estimated value for the sales price can be determined on the basis of a database, for example via the Internet portal www.dat.de. The method is used for the automated creation of a price tag that can be placed behind the windshield in a motor vehicle in order to offer this motor vehicle for sale. The motor vehicle to be sold is then already at the dealership, ie it has already been bought from the previous user.

From the KR 20000063995 A an internet-based sales portal for motor vehicles is known, in which the vehicle sale can be processed completely digitally via the internet. For this purpose, different views of the motor vehicle are provided as photos in the internet portal.

The price the potential buyer is willing to offer depends on his assessment and negotiating skills.

The systems described here for selling a motor vehicle can of course also be useful for selling another device, for example a mobile terminal device or a computer or a consumer electronics device (for example television).

The object of the invention is to support a user of a device in carrying out the complex estimation procedure for determining an estimated value of a sales price several times with little effort in order to recognize over a period of time when the device is cheap to sell.

The object is solved by the subject matter of the independent patent claims. Advantageous embodiments of the invention are described by the dependent patent claims, the following description and the figures.

The invention describes a method for operating a user interface for displaying a device status of a device. The method includes measuring or acquiring respective predetermined status data of the device by a control circuit of the device and/or by a device-external server device during operation of the device and/or between two operating phases of the device and/or from a respective data memory at least one device component of the device and/or read from a database and these status data are then combined into a status data set. In the case of a device representing a motor vehicle, the control circuit can be implemented, for example, by a central computer of this motor vehicle. A device-external server device, on the other hand, can be implemented, for example, by an Internet server, which can be implemented as an individual computer or as a computer cloud. Said status data can be recorded while the device is in operation or also when the device is switched off, when it is not being operated but is switched off in stand-by mode, for example. In the case of a motor vehicle, the status data can thus be determined, for example, while the motor vehicle is being driven and/or when it is parked. The component status data for this device component can be determined from a respective data memory of individual device components, this being, for example, an indication of the component model (e.g. in the case of a motor vehicle a version of a control device or control device software) and/or usage data, such as elapsed operating hours can. The individual component status data may together represent the status data or a part thereof. A database for further status data can also be provided outside of the device, for example at a workshop or at a dealer for the device. For example, maintenance work and/or repairs that have been carried out and/or registered damage or accidents can be read out as status data from such a database. Status data can thus be compiled from the data sources described, without any action on the part of the user, which describes the status of the device, for example the equipment and/or the usage history of the device, in particular a motor vehicle. This results in respective attribute values for a large number of different device attributes, which are described by the status data, for example the device model (device type) and/or the device age and/or the mileage or usage time and/or repairs and/or a replacement of at least one device component .

The status data set thus represents a multi-dimensional status vector in the status space of the possible statuses of the device, with each dimension or each entry of this status vector specifying an attribute value for a specified device attribute, for example device age, device model, presence of a specific device component, such as an air conditioning system in a motor vehicle can.

The method also includes that an estimated value for a sales price of the device is determined by the server device from the status data record using a predetermined comparison method using at least one reference status data record, with a respective reference sales value being assigned to the respective reference status data record for this purpose, and the estimated value being sent to the user interface. These process steps compensate for the fact that, of course, no exactly the same device in the same device condition (i.e. with the same condition vector) has already been sold on the market for used devices and its sales price can therefore be used directly or unchanged as a reference sales value. Rather, there are only similar ones Devices, i.e. with a similar condition vector, which have been sold before, where "similar” means that there are similar equipment and/or similar states of wear or condition data, but a difference is smaller than a specified tolerance value. In the case of a motor vehicle, for example, the same can be true Vehicle model must have already been sold before, but had a different mileage (mileage driven) and/or had different device equipment (e.g. with or without air conditioning). Thus, the attribute values of the device attributes (mileage and/or equipment) are different for the device that has already been sold. This results in a reference status data record for this other device. This may have been a device that may have shown little or greater wear and/or may have had more or less equipment with device components. In relation to each device attribute, the device currently to be sold or to be valued must be placed in relation to the reference devices whose reference condition data record is known and whose reference sales value is known. For example, a reference device may have had more operating hours or mileage, but a certain device component, such as a transmission or a brake system, was less worn. If the device currently being evaluated has fewer operating hours or mileage, its estimated value increases relative to the reference sales value, but if there is greater wear on a specific device component, for example the transmission or the brake system in question, this must be offset. The comparison method can include at least one table and/or an interpolation routine here, for example, in order to use the at least one reference status data record to calculate an estimated value for the sales price for each device attribute to investigate. Such a comparison method can be implemented as software or program code for a processor circuit of the server device.

Finally, the method includes the user interface displaying the determined estimated value as part of the display or display graphic on the user interface to a user of the device and additionally displaying at least one interaction element and, upon detection of a user-side interaction with the respective interaction element, a respectively assigned communication function for sending out a message dependent on the estimated value is started. The user interface can, for example, display or output the display on a touch screen. If the user then operates a displayed interaction element, for example a touch panel, via which an interaction or an input by the user is recorded, then the communication function assigned to this interaction element is started. An additional or alternative configuration of the interaction element can provide voice recognition, so that the interaction can take place via voice and a voice dialog system with commands and voice output. [Note, 24.9: The interaction could also take place via speech and speech dialog systems with commands and voice outputs] For example, a message with a sales offer can be sent to a predetermined address by the communication function and the estimated value itself or an offer value based on the estimated value can be contained in this sales offer in which, for example, in addition to the estimated value, a surcharge desired or entered by the user, for example in a range from 3% to 15%, is taken into account.

This method can of course be iterated over and over again, so that a user can advantageously track or observe the estimated value of the selling price for his device over time and, in the event that he decides to sell, the at least one interaction element to start with or triggering the communication function to send out the message, which can be sent to a dealer or a used equipment market as an offer, for example.

The invention also includes embodiments that result in additional advantages.

Advantageously, to whom the notification is sent should be determined such that after sale, a transportation distance is no longer than a threshold. One embodiment therefore includes that a position detection circuit of the device is used to determine whereabouts data of a location area in which the device is located with a predetermined minimum frequency (e.g. measured by the length of stay), and when the user interacts with the at least one interaction element, a communication link to a dealer for a purchase of the device is mediated, the dealer being selected from a list of several dealers based on the location data in such a way that a resulting transport route of the device to the dealer according to the location data is less than a predetermined maximum value or in whose sales area the location is located. A dealer who might be interested in purchasing the device can thus be informed by an interaction element with an associated corresponding communication function. Since the removal or receipt of the device after a purchase can again involve transport costs, these should be within a range that can be specified by the maximum value. This is ensured by the embodiment described. A direct sale to a dealer can therefore be mediated. The message that is sent can, for example, prompt the dealer to contact you by sending the dealer the estimated value of the sales price or the offer value adjusted in the manner described and optionally also providing status data from the status data record. The position detection circuit can for example be based on a receiver for a position signal of a GNSS (Global Navigation Satellite System), for example the GPS (Global Positioning System). In one embodiment, a workshop history of the device user (e.g. vehicle user) is used to select the suggested dealer, so that the previously visited dealer is highlighted in the display or sorted at the top of a displayed selection list. No position data is then preferably required for this function and it allows a device user to quickly find the dealer he knows even at a greater distance from his home location. The described selection of a local dealer for the owner of the device is not displayed in an alternative embodiment if this is not the case is relevant.

One embodiment includes that at least part of the status data record is also provided in the user interface and when the user interacts with the at least one interaction element, an internet-based sales platform for the device is called up and an advertisement form for the device is automated for the user based on the provided part of the status data record is filled in. So it can be provided an interaction element by means which not a dealer is contacted for a direct sale, but a sales platform. The user can be supported in filling out an advertisement form. The user then only has to agree to the coupling of the motor vehicle to the sales platform, status data and/or equipment data from the status data record are then automatically transferred from the motor vehicle to the sales platform.

One embodiment includes that at least one historical status data record determined in the past is stored and the comparison method includes that a respective historical sales price is determined and a performance representation of the sales price is determined from this and displayed as part of the display. The historical sales price can be an actually realized sales price that can actually have been achieved for a reference device on the day in the past. Here you are not dependent on an estimated value. However, an estimated selling price can also be provided as the historical selling price. Now, for example, by displaying a graph or table of historical sales prices and an estimate of the current sales price, the user can observe a price fall or (in the case of a collector's item, for example) a price rise. This advantageously supports the user in determining a sale time that has a predetermined optimization criterion, for example an extreme value or turning point (if the slope of the value development representation is 0).

Advantageously, however, a user can also be assisted in estimating how the sales price will develop in the future if the user continues to use his device, for example his motor vehicle, as he has previously done. For this purpose, one embodiment includes that by means of a predetermined extrapolation method for the status data record on the basis of usage data, which results in usage behavior observed in the past by the user and/or at least one co-user in relation to the device, at least one extrapolated status data record that shows a future development of the status data record is extrapolated and a future estimated value of the sales price is determined by the comparison method for the respective extrapolated status data record and an estimated future development of the sales price is displayed as part of the display. The usage data is therefore used to determine what wear and tear occurs in the device in a predetermined unit of time, for example within a week or within a month. The time unit can range from one day to, for example, six months. It can thus be determined for individual device components of the device how far the wear and tear will develop in the future if the usage behavior remains the same. An extrapolated status data set can be determined from this and this can be mapped using the comparison method in a future estimated value or an extrapolated estimated value. This can then also become part of the display of the user interface. A user can thus estimate how his driving behavior (in the case of a motor vehicle) and/or the frequency of maintenance affect the sales price. The extrapolation can be carried out, for example, on the basis of a machine learning method, for example using an artificial neural network. This can be trained with sample data from reference devices. The user can thus recognize if his device does not stand up to his usage behavior, ie shows an excessive drop in price because the user overloads the device, for example. In addition, other influences can be incorporated into the extrapolation method, for example the release date of a new device model of the device and/or a season (e.g. convertibles are more expensive in spring than in autumn) and/or demand behavior of prospective buyers (aggregated demand on the market for used devices) .

One embodiment includes that the user interface is operated at least partially by an operating circuit of the device itself and/or by an application program of a mobile terminal device of the user and/or by a website of a device-related internet portal. Said user interface can show the display on a screen or display, for example a touch screen (touch screen). This can include, for example, an operating circuit of the device itself. In the case of a motor vehicle, this can be the so-called infotainment system (information entertainment system) or the MMI (man-machine interface). In addition or as an alternative to this, at least part of the user interface can be implemented by a mobile device or a voice dialog system or a TV set. The application program that can be used for this purpose is also generally referred to as an app. It can also be used in web portal as part of the user interface that provides a website where the user can manage their device. This is known, for example, for motor vehicles.

As already explained, the difficulty in determining an estimated sales price lies in the fact that reference devices usually do not be in the same condition as the device currently being estimated or evaluated. In the case of a motor vehicle, for example, a device can have a greater mileage, but at the same time exhibit less wear on a transmission. The device currently being evaluated should therefore result in a higher estimated value in relation to the mileage, but this estimated value would have to decrease again with a more heavily worn gearbox. Thus, generally different device attributes are advantageously initially to be evaluated individually by an attribute value.

One embodiment therefore includes that the comparison method provides that a respective attribute value is determined from the status data record for different device attributes of the device and an attribute-related estimated attribute value for the sales price is determined using a respective corresponding reference attribute value from the at least one reference status data record for the respective device attribute and the estimated attribute values of the different device attributes are weighted by means of a predetermined weighting and combined to form the actual estimated value. Said device attributes can, for example, include at least one of the following: device model, device age, service life, mileage (in the case of a motor vehicle), device configuration of device components, load profiles of at least one device component, such as counted kickdown accelerations in an automatic transmission, damage registered in a workshop. The estimated attribute value can be determined for each device attribute, i.e. a sales price that resulted for a reference device with the corresponding attribute value. The attribute-related attribute estimate results from interpolating and/or forming a ratio between these values. For example, if the mileage of a reference device is X kilometers and the device to be evaluated has a mileage of 0.7 x X kilometers, the estimated attribute value can be 1/0.7 of the reference sales price, for example, if a proportional ratio is provided. However, another curve, for example the square root, can also be used as a basis for forming the ratio, which can result in a value of 1/0.837 in the example mentioned. This allows estimated attribute values for different device attributes to be determined. Each attribute estimate can then be scored or weighted with a multiplicative weight or proportion weight. Here, a person skilled in the art can assign different weightings or information for the importance of a device attribute. The weights can add up to 1. The estimated value then results from weighted summarization, for example a weighted mean value. The comparison method can additionally or alternatively, on the basis of clustering, summarize the reference status data sets of several reference devices in said vector space and/or provide a distance or a metric of the status data set with respect to the reference data sets and/or clusters in order to scale the reference sales values. The known reference attribute values can be connected, for example, by means of an interpolation in order to interpolate an estimated value of a sales price for intermediate values. The device attributes can be evaluated and summarized, for example, on the basis of a machine learning method, in particular an artificial neural network, which can be trained with reference data records from different reference devices and the reference sales price achieved in each case.

One embodiment includes that the status data for the status data record included at least some of the following: model data of a device model of the device and/or equipment data of a device equipment of the device (i.e. currently installed device components) and/or maintenance data of performed device maintenance and/or usage data of usage processes of the device. In this way, both fixed attributes, such as the device model and existing equipment, and variable attributes, such as retrofitted, currently installed device components and use-related wear and tear, as well as upgrading measures such as maintenance and repairs, can be taken into account.

The invention also provides a system that includes at least one device that has a control circuit that is set up to measure respective predetermined status data of the device during operation of the device and/or between two operating phases of the device and/or from a respective data memory read at least one device component of the device and/or from a database and combine the status data into a status data record and send it to a server device external to the device. The system is able to carry out an embodiment of the method according to the invention.

For this purpose, the system further provides that the server device, which has a processor circuit that is set up to determine a ratio value with regard to at least one reference status data record from the status data record using a predetermined comparison method, with the respective reference status data record being assigned a respective reference sales value, and based on of the determined ratio value and based on the respective reference sales value of the at least one reference status data set to determine an estimated value for a sales price of the device and to send it to a user interface. In the server device, the processor circuit can therefore carry out those method steps which are provided in the method for the server device.

The system further provides for a user interface that is set up to receive the estimated value determined from the server device and to display it to a user of the device as part of a display. The user interface can be implemented in the manner described in the device or in an internet portal or on a mobile device, such as a smartphone or a tablet PC.

The invention also provides a device for the system described, the device having a control circuit set up to measure respective predetermined status data of the device during operation of the device and/or between two operating phases of the device and/or from a respective data memory read at least one device component of the device and/or from a database and combine the status data into a status data record and send it to a server device external to the device. According to one embodiment, the device is designed as a motor vehicle. The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle. According to one embodiment of the method according to the invention, a user of the device can therefore be kept informed about a current estimated value of a sales price of the device and is provided with at least one interaction element in order to be able to send said message regarding the estimated value of the sales price.

In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that are to be considered independently of one another and that each also develop the invention independently of one another. Therefore, the disclosure is also intended to encompass combinations of the features of the embodiments other than those illustrated. Furthermore, the described embodiments can also be supplemented by further features of the invention that have already been described.

In the figures, the same reference symbols designate elements with the same function.

1 shows a system 10, by means of which a user 11 of a device 12 can be provided with a user interface 13, on which the user 11 is shown a display 14 relating to a currently achievable sales price 15 and through which he is immediately given the opportunity to sell the device 12 to initiate or begin via at least one interaction element 16 . The display 14 can take place, for example, on a touch screen or a screen. The respective interaction element 16 can be a touch panel on a touch screen or a control button. An interaction element 16 can be used, for example, to initiate contact 17 with a dealer 18 who can be located in a predetermined location area 19 in which the device 12 is located with a predetermined minimum frequency. The device 12 can be a motor vehicle, for example. The contact 17 with the dealer 18 can be done, for example, by a message 22, in which the estimated value V0 can be included as an offer (for example: "I would sell you my car for V0 EUR. Please contact me about this.", V0 for this a purchase amount).

In order to determine the estimated value V0 in each case, the server device 20 can, for example, receive a current status data record 23 with current status data 24 relating to the device 12 from the device 12 . For this purpose, the device 12 can have a control circuit 25 which the status data 24 can be read out, for example, from one or more control devices 26 of the device 12 . The status data 24 can be transmitted to the server device 20 as a status data set 23 for example via a radio link 28 and for example via a mobile radio network 29 and/or an Internet connection 30 by means of a communication circuit 27 . The server device 20 can then use a predetermined comparison method 31 to determine the estimated value V0 and output this to the user interface 13 for display on the display 14 . If the user 11 operates one of the interaction elements 16, this can be detected by the server device 20 or signaled by the user interface 13 of the server device 20, and this can transmit the message 22 to the trader 18, for example with the estimated value V0. The dealer 18 can then contact the user 11 of his own accord.

2 illustrates a possible configuration of the display 14 of the user interface 13. The user 11 can, for example, be made an offer as a menu item 33 in an operating menu of the user interface 13: "Would you like to sell your device?" can in particular be a motor vehicle. In a value development display 34, for example as a diagram or graph, in addition to the estimated value V0, for the current day T over time, a historical development of the sales price V can also be displayed in a diagram 35 or (not shown) in a table. A predetermined historical period 36 can be specified here, for example the sales price V of the last thirty days. The historical period 36 can range from two days to one year, just to name examples. An interaction element 16 can be provided in the manner mentioned for triggering the message 22 for a dealer 18, wherein the dealer 18 can be selected automatically by the server device 20 and for this purpose the area 19 of the device 12 can be taken into account. Another interaction element 16 can provide that when it is actuated, an internet portal 37 is controlled and the estimated value V0 and the status data 24 are transmitted as input data 38 for filling out an advertisement form 39, so that the user 11 has the advertisement form 39 filled out in automated form. A future sales price V can also be estimated using an extrapolation method E.

3 12 illustrates one embodiment of comparison method 31 as may be performed by server device 20. FIG. Reference status data sets 40 can be determined for reference devices from past sales, which records contain the respective reference attribute value 43 of the respective reference device as reference status data 41 for different device attributes 42 . Three device attributes GA1, GA2, GA3 are shown here as examples. Such a device attribute can be, for example, a total operating time that has elapsed and/or a device attribute (for example color) and/or a number of specified events, such as emergency braking or kickdown acceleration in a motor vehicle. A reference sales price 44 can be specified for each reference device, as was achieved for the respective reference device.

The comparison method 31 can provide that now for each device attribute GA1 from the respective reference state data record 40 it is determined which reference attribute value 43 was given and which reference sales price V resulted for the respective reference device. If the attribute value 45 determined from the status data record from the status data 24 is then entered for the current device 12, a first estimated value V1 for the sales price V can be determined as an interpolation 46 from the reference sales prices 44 in relation to the device attribute GA1. This can be done for any of the remaining device attributes GA2, GA3 and other device attributes represented here by ellipses 48. The interpolation 46 results in an attribute-related estimated value V2, V3 and so on. By means of a respective weighting 49, for example with a weighting factor F1, F2, F3,... through which a contribution or a meaning of the respective device attribute 42 for the sales price V is expressed or described, a summary 50 of the weighted attribute-related sales prices V1 , V2, V3, the estimated value V for the sales price 15 can be determined, with the summarization e.g. adding up and dividing by the sum of the weighting factors F1, F2, F3, . . . The comparison method 31 can also be carried out using an artificial neural network.

The user 11 does not have to determine an estimated value V0 for the selling price 15 each time he is interested in a sale. Rather, a server device 20 on the Internet 21 can continuously make a current estimate of the sales price 15 for the user 11 and present it as an estimated value V0 on the display 14 of the user interface 13 . The server device 20 can be a server of the Internet, for example. The user interface 13 can be used as part of the device 12 and/or as an appli be configured cation program of a mobile terminal.

Der Benutzer kann dafür einen Link erhalten, um das Angebot fertig zu bearbeiten (z.B. Fotos hochladen), um sein Auto zu verkaufen.

With this, the process of selling equipment, especially selling a car, is a straightforward process. A simple solution exists for the user. The user can be provided with two control options by means of the interaction elements 16 . In the case of a motor vehicle or car, these are:

1. 1) Selling from the car to a dealer with one click or pressing an interaction element 16. The display of the historical purchase price in the car directly in the infotainment system and/or via an app on a mobile device for the user. On the server side, a database can describe the configuration of the device. For example, if the user has clicked “Sell”, his local dealer can come to the user with the money and a purchase agreement within a specified period of time, for example 24 hours, and take the car with him. The user can still withdraw until then.
2. 2) The sale can take place by operating an interaction element 16 through online sites on a sales platform such as Autoscout24.de, Mobile.de. The historical purchase price in the car can be displayed directly in the infotainment system and/or via an app on a mobile device for the user. On the server side, a database can describe the configuration of the device. When the user selects "Sell via..." a pre-made listing form is created from this fitment database. In return, the user can receive a link to finish editing the offer (e.g. upload photos) in order to sell his car.

1. A) Traditionell kann es persönlich durch einen Angestellten 54 des Händlers 18 (Person) abgeholt werden.
2. B) Im Falle eines autonomen Fahrzeuges (SAE Level 5 - autonom ohne Fahrer) fährt das Gerät 12, nachdem der vorhergehende Besitzer alle Zubehörteile (z.B. Schlüssel, Dachträger) in das Gerät 12 gegeben hat, sich selbst zum Händler 18 Insbesondere kann die Möglichkeit vorgesehen sein, die vollständige Stückliste der Zubehörteile (z.B. „2x Schlüssel, Dachträger, Bordbuch, Wagenheber“) durch einen NFC-Tag sicher zu stellen und über geeignete Maßnahmen (z.B. Bildschirm, Sprachmeldung) den Besitzer auf fehlende Teile oder Vollständigkeit hinzuweisen.
3. C) Es kann eine Flugdrohne 51 das Gerät 12 an einem dafür vorgesehenen Landeplatz 52 aufnehmen und über den Luftweg 53 zum Händler 18 oder zu einem ausgewiesenen Platz befördern.

This makes selling a car convenient and/or technically error-free. The current estimated value VO for a sales price of 15 can be viewed by clicking in the operating menu. The dealer can pick up the device the next day, or alternatively, an advertisement can be prepared with one click on a sales platform. 4 shows how, after the device 12 has been sold to the retailer 18, one of three exemplary transport methods A, B, C can be used to transport the device 12 sold to the retailer 18:

1. A) Traditionally, it can be picked up personally by an employee 54 of the dealer 18 (person).
2. B) In the case of an autonomous vehicle (SAE Level 5 - autonomous without a driver), the device 12, after the previous owner has placed all accessories (e.g. keys, roof rack) in the device 12, drives himself to the dealer 18 In particular, the possibility can be provided be to ensure the complete parts list of the accessories (e.g. "2x keys, roof rack, log book, jack") using an NFC tag and to use suitable measures (e.g. screen, voice message) to inform the owner of missing parts or completeness.
3. C) A flying drone 51 can pick up the device 12 at a landing site 52 provided for this purpose and transport it via the airway 53 to the dealer 18 or to a designated place.

Overall, the examples show how a put option can be provided for a device.
