Description

[0001] LIGHT GENERATING SYSTEM WITH OPTICAL PATTERNS PROVIDING SYSTEM

[0002] INFORMATION

[0003] FIELD OF THE INVENTION

[0004] The invention relates to a system comprising a light generating device. The invention further relates to a lighting device. The invention further relates to a method for accessing a part of system information of a system.

[0005] BACKGROUND OF THE INVENTION

[0006] Methods for accessing information via optical patterns are known in the art. For instance, US2020184169A1 describes that information is recorded in quick response codes. A hologram is made from quick response codes and provides three dimensions of information in a two-dimensional hologram. The holograms are used for recording information in two dimensions. Multiple quick response codes containing copious information are created using different light wave frequencies in different quick response encoders. The multiple quick response codes are combined in a two-dimensional hologram that is used on labeling. The hologram is read by a hologram reader. Each quick response frequency layer is separated from the hologram. The quick response code is extracted from each layer. A quick response reader provides the information that has been recorded.

[0007] SUMMARY OF THE INVENTION

[0008] Products, such as lighting products, or their packaging may contain optical patterns, such as Quick Response (QR) codes, providing access to product-related information. Typically, if a product contains multiple such codes, the codes may provide identical information. This information may, for instance, be convenient (a) for consumers to gain insight into product characteristics pre-purchase, (b) for installers to gain access to assembly or installation instructions, and (c) for maintenance engineers for troubleshooting, acquiring suitable spare parts and changing system settings. However, for these examples, the different people may preferably be presented with information tailored for their specific situation. For instance, for an installer, a QR code may be used to connect a product to an existing network, e.g., a Wi-Fi network, or to set a product setting, e.g., a location setting based on a local GPS coordinate. However, although such QR codes may be intended for being used at a final use location, in practice these may often be used during assembly in a workshop. Thereby, as an example, GPS coordinates encoded in a system, such as in a street lighting pole, may erroneously indicate the GPS coordinate of the workshop in which the system was assembled, rather than the location at which it operates. Such erroneous encoding of a GPS coordinate may hamper maintenance of the system as well as location-based control of light generating devices, such as of street lighting poles.

[0009] Further, it may be undesirable that each person that can access a product may be able to acquire the same information. For instance, for systems arranged in the public domain, such as lighting poles for street lighting, it may be convenient for a maintenance engineer to be able to access lighting control settings via a QR code, but it may be undesirable if a random passerby could access the same lighting control settings.

[0010] Further, re-use of a code may complicate future updates or extended rights related to a specific component of a product.

[0011] Hence, there may be a desire for a system facilitating installation of a lighting device and / or for providing appropriate system information to different users.

[0012] Hence, it is an aspect of the invention to provide an alternative system, which preferably further at least partly obviates one or more of above-described drawbacks. The present invention may have as object to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.

[0013] Hence, the present invention is set out in the appended set of independent and dependent claims.

[0014] According to a first aspect, the invention provides a (lighting) system comprising a light generating device, a first location and a second location, especially wherein the first location and the second location are spatially separated, and especially are both arranged on different surfaces of the light generating device. In embodiments, the first location comprises a first optical pattern providing first information or providing access to the first information, especially wherein the first information comprises or provides access to a first part of system information (relating to the system). Similarly, in embodiments, the second location comprises a second optical pattern providing second information or providing access to the second information, especially wherein the second information comprises or provides access to a second part of the system information. Alternatively, the second location comprises a wireless transmitter having a transmitter range (R) configured to provide a wireless signal comprising second information. The first part and the second part (of the system information) may be at least partially non-overlapping, i.e., may be at least partially non-overlapping in content of the system information. In embodiments, the first information and the second information may together provide, e.g., encode, third information, especially wherein the third information comprises or provides access to a third part of the system information. In particular, at least part of the system information may be included in the third part but excluded from the first part and from the second part, i.e., at least some of the content of the third part of system information is not included in the first part of the system information, nor in the second part of the system information. The system information may, in embodiments, comprise one or more of product information, historic information, maintenance information, location information, and (control) access information.

[0015] In embodiments, the invention may provide a system comprising a light generating device, a first location and a second location, wherein the first location and the second location are spatially separated, wherein the first location comprises a first optical pattern providing first information or providing access to the first information, and wherein the second location comprises a second optical pattern providing second information or providing access to the second information, wherein the first information and the second information together provide third information, wherein the third information comprises or provides access to a third part of the system information, wherein the system information comprises one or more of product information, historic information, maintenance information, location information, and access information. In particular, at least part of the third part of the system information may not be accessible via only one of the first information and the second information.

[0016] In an embodiment, the third part of the system information is different from the first part and from the second part for the system information. In embodiments, the first information and the second information may together provide, when scanned successively or simultaneously, the third information.

[0017] In an embodiment, the first part of the system information is a first type of information (e.g. product information), the second part of the system information is a second type of information, wherein the first type of information and second type of information are the same or different, wherein the third part of the system information is a third type of information (e.g. history information, maintenance information, etc.), which third type of information is different from the first type of information and the second type of information. In an embodiment, the third part of the system information is only maintenance information, e.g. related to the light generating device. In an embodiment, the third part of the system information is control information, e.g. for controlling the light generating device.

[0018] In specific embodiments, the invention may provide a system comprising a light generating device, a first location and a second location, wherein the first location and the second location are spatially separated, wherein the first location comprises a first optical pattern providing first information or providing access to the first information, and wherein the second location comprises a second optical pattern providing second information or providing access to the second information, wherein the first information comprises or provides access to a first part of system information, and wherein the second information comprises or provides access to a second part of the system information, wherein the first part and the second part are at least partially non-overlapping, wherein the first information and the second information together provide third information, wherein the third information comprises or provides access to a third part of the system information, and wherein at least part of the system information is included in the third part but excluded from the first part and from the second part, wherein the system information comprises one or more of product information, historic information, maintenance information, location information, and access information.

[0019] With such a system, access to system information, optionally including access to system control settings, can be selectively made available based on a status of the system and physical access to the system.

[0020] Thereby, system information, such as production information, may be selectively accessible at an appropriate time. For instance, (a part of) product information, such as installation-related information, or such as assembly information, may be selectively accessible prior to and / or during installation / assembly. For instance, an optical pattern may be (visually) accessible prior to assembly but may be (visually) inaccessible once the system is fully assembled. Alternatively or additionally, accessing the installation-related information may require information encoded in an optical pattern arranged on packaging of other system components, i.e., of other components of the system. Yet further, particularly for a modular system, scanning optical patterns of different system components may provide installation-related information specifically directed to the combination of the components at hand. As a further example, late-stage configuration settings may only be accessed during or following installation of the system at its target site. For instance, for lighting poles in the public domain, the system may facilitate (only) entering coordinate settings once the system is installed. For instance, this could be arranged by requiring access to an optical pattern that is (essentially) only available during installation or following installation, e.g., via a moving part or by bringing two parts together.

[0021] Hence, the invention may facilitate differentiating access of lighting settings depending on (physical) access. For instance, in the context of a lighting pole (comprising a luminaire) with optical patterns comprising QR codes: QR code on package - only standard information including factory settings; QR code on pole - Only type information, no driver setting information; QR code in luminaire - Lighting Sub Circuit (LSC) information, access to sensitive information (e.g. the identity of the owner of the luminaire, and / or component information); access to QR code on package and QR code in luminaire - access to luminaire control settings.

[0022] For instance, different authorization levels may be defined by using different optical pattern combinations, especially QR code combinations. E.g. the first level can only adapt the time schedule which may typically be done 2 times a year for the winter and summer schedule. A second level can also adapt the color temperature of the light or other higher level driving settings: dimming schedules, how to respond to movement sensor input.

[0023] Further, different optical patterns, such as QR codes, can be used to differentiate between different levels of pole hierarchy or type of connectivity. For example, only one out of 10 poles can be connected as "master" to an external city network, whereas the other 9 "Client" poles are only locally connected to this "master" pole (e.g. via BT or Zigbee or another mesh network). The optical pattern on the "Client" poles may provide less (access) rights than the optical pattern on the master pole (which could also be hidden behind a lockable door in the pole). Thereby, the invention may facilitate convenient installation, use and maintenance of the system (or a related lighting device), and may further facilitate securing access to non-public information, such as securing access to control information.

[0024] Hence, the invention may provide a system comprising a light generating device. Such system may herein also be referred to as a lighting system or light generating system. The term “light generating device” may herein refer to a device configured to generate device light (or “lighting device light”), especially for outdoor lighting, such as for garden lighting, street lighting or park lighting. The system may especially be configured to generate system light, wherein the system light comprises at least part of the device light. The system may, in embodiments, comprise a first location and a second location, wherein the first location and the second location are spatially separated. For instance, the first location and the second location may be arranged on different components of the system, e.g., on the base of a lighting pole and inside of a luminaire, or e.g., on a system component and on packaging of the system component or another system component. The term “component” may herein refer to any part of the system, such as a housing, a light source, a pole, attachment means, etc.. Hence, the first location may be arranged on a first (physical) component of the system and the second location may be arranged on a second (physical) component of the system. In embodiments, the first component and the second component may, in at least one assembly of the system, be (directly or indirectly) physically connected.

[0025] In further embodiments, the first location may especially comprise a first optical pattern. Similarly, in further embodiments, the second location may comprise a second optical pattern. Hence, in embodiments, the first location may comprise a first optical pattern and the second location may comprise a second optical pattern.

[0026] The term “optical pattern” may herein refer to any visible pattern suitable to provide, especially encode, information, such as based on an image of the optical pattern. The optical patterns may especially be at least partially non-verbal, especially essentially nonverbal, i.e., the first optical pattern and the second optical pattern may be at least partially non-verbal, especially essentially non-verbal. For instance, the optical pattern may comprise a barcode. The optical patterns may, for instance, comprise patterns of dots, lines and / or colors. The optical patterns may especially comprise 2D optical patterns, such as 2D barcodes, especially QR codes (quick-response codes).

[0027] The invention may herein for explanatory purposes primarily be discussed in the context of optical patterns comprising QR codes. It will be clear to the person skilled in the art, however, that the invention is not limited to such embodiments.

[0028] Hence, in embodiments, the first optical pattern may comprise a 2D optical pattern, especially a QR code, configured such that therein encoded information can be retrieved based on a (camera) image of the first optical pattern.

[0029] Similarly, in embodiments, the second optical pattern may comprise a second 2D optical pattern, especially a second QR code, configured such that therein encoded information can be retrieved based on a second (camera) image of the second optical pattern.

[0030] For instance, in embodiments, the information encoded in the first optical pattern and / or the second optical pattern may be retrieved (or “decoded”) using a smartphone, such as via a typical QR code scanner, or such as via a dedicated smartphone application (or “app”).

[0031] In further embodiments, the system may include a scanner and a user interface, wherein the scanner comprises or is functionally coupled to the user interface. In particular, the first optical pattern and the second optical pattern may be scannable by the scanner. Hence, the scanner may be configured for scanning the first optical pattern and the second optical pattern. In particular, the user interface may be configured to provide, especially display, the third part of the system information (also see below) when the scanner (successively) scans the first optical pattern and the second optical pattern, especially within a predefined time window. In embodiments, the predefined time window may be selected from the range of 1 - 600 s, such as from the range of 1 - 300 s, especially from the range of 2 - 120 s. In further embodiments, the user interface may be configured to provide, especially display, the third part of the system information when the first optical pattern and the second optical pattern are scanned together.

[0032] In particular, the first optical pattern may provide first information or may provide access to the first information. Especially, the first optical pattern may encode the first information (directly) or may encode a link to the first information.

[0033] Similarly, in embodiments, the second optical pattern may provide second information or may provide access to the second information. Especially, the second optical pattern may encode the second information (directly) or may encode a link to the second information.

[0034] As the first optical pattern and the second optical pattern respectively provide (access to) first and second information, it will be clear to the skilled person that the first optical pattern is different from the second optical pattern. Hence, in embodiments, the first optical pattern differs from the second optical pattern.

[0035] The first information and the second information may both comprise or provide access to respective parts of system information. In particular, in embodiments, the first information may comprise or provide access to a first part of system information. For instance, the first information may contain a link suitable for accessing the first part or may contain a passcode suitable for accessing the first part (of system information). Similarly, in embodiments, the second information may comprise or provide access to a second part of the system information. The first part and the second part may be at least partially nonoverlapping. In further embodiments, only one of the first information and the second information may comprise or provide access to part of the system information. In yet further embodiments, the first information and the second information may separately not comprise or provide access to part of the system information. In particular, in such embodiments, the first information and the second information may together provide a third part of the system information (via third information; see below).

[0036] The term “system information” may herein refer to any information related to the system, especially to the light generating device. In embodiments, the system information may comprise one or more of product information, historic information, maintenance information, location information, and (control) access information.

[0037] Hence, in embodiments, the system information may comprise product information, especially in relation to the light generating device. The term “product information” may, for instance, comprise one or more of a product type, a product number, a product identification code, a batch number, etc. The product information may, for instance, be suitable for identifying the product and ordering replacement products and / or replacement product parts. In embodiments, the product information may comprise installation(-related) information. In further embodiments, the product information may comprise assembly information.

[0038] In further embodiments, the system information may comprise historic information, especially in relation to the light generating device. The term “historic information” may herein refer to information related to the history of the specific system (or device). For instance, the historic information may include information on (a) shipping of the system (or components thereof), (b) assembly of the system, optionally including information on the date, time, location, and assembler, (c) operational performance, (d) maintenance events, e.g., including information on what was fixed / replaced when and by whom, and (e) malfunction events. The historic information may, for instance, be useful for troubleshooting, identifying malfunctioning parts, and evaluating overall performance.

[0039] In further embodiments, the system information may comprise maintenance information, especially in relation to the light generating device. The term “maintenance information” may herein refer to information relevant for maintenance of the system. For instance, the maintenance information may comprise information on component status, e.g., including expected remaining lifetime. The maintenance information may be particularly useful for a maintenance engineer to determine the suitable actions when performing maintenance on the system. In further embodiments, the system information may comprise location information, especially in relation to the light generating device. The term “location information” may herein refer to information on the location and / or intended location of the system. For instance, the location information may comprise coordinates, such as Global Positioning System (GPS) coordinates, or relative positioning information. The location information may facilitate determining whether the correct system is being checked and may facilitate location-specific control of the system. As described above, prior art systems may regularly erroneously be assigned coordinates of their place of assembly rather than the coordinates of their (intended) location of operation. A mismatch in the coordinates in the system information with the actual location of the system may result in improper system operation, such as in the context of street lighting activating at an incorrect time (street lighting in a light open space may be operated on a different time schedule than street lighting in a relatively dark space, such as along a forest path), or such as in the context of traffic lights.

[0040] In further embodiments, the system information may comprise access information, especially in relation to the light generating device. The term “access information” (or “control access information”) may herein refer to information granting (partial) access to the system, especially to operational settings of the system, such as of the light generating device. In embodiments, the access information may comprise information granting (partial) access to a control system (see below). For instance, the control system may be configured to (adjust) control (or “adjust settings”) of the light generating device when receiving corresponding control input comprising an access key, wherein the access information comprises such access key. For example, the control system may be configured to, upon receiving the control input, control , especially adjust a setting of the light generating device, wherein the setting comprises one or more of intensity, a time schedule, a color temperature, etc.

[0041] It will be clear to the person skilled in the art that the herein described categories of system information may be partially overlapping. E.g., historic information may contain information on maintenance events, which information may also be relevant for maintenance and thus be included as maintenance information.

[0042] In embodiments, the first information and the second information may (further) together provide, such as encode, third information. The third information may comprise or provide access to a third part of the system information. Especially, at least part of the system information is included in the third part but excluded from the first part and from the second part. Hence, the combination of the first information and the second information may provide additional (third) information not contained in the first information nor in the second information. In particular, the third part may comprise access information, especially wherein (at least part of) the access information is not contained in the first part nor in the second part.

[0043] For instance, the first information and the second information may respectively comprise a link requiring an access code for access and the corresponding access code (or vice versa). Alternatively, for example, the first information and the second information may respectively comprise an encoding and a decoding key (or vice versa). Yet further, the first information and the second information may both comprise a partial encoding, which encodings may be combined into a combined encoding providing (access to) the third information. It will be clear to the person skilled in the art that many variations may be possible without deviating from the concept of the first information and the second information together providing the third information.

[0044] In embodiments, the first information comprises or provides access to a first encoding, the second information comprises or provides access to a second encoding, wherein the first encoding and the second encoding together provide the third information.

[0045] In further embodiments, the first information comprises the first encoding, i.e., the first information (directly) contains the first encoding. Similarly, in further embodiments, the second information comprises the second encoding.

[0046] In further embodiments, the first information comprises a first link to the first encoding. In further embodiments, the first information comprises a first access code for accessing the first encoding.

[0047] Similarly, in further embodiments, the second information comprises a second link to the second encoding. In further embodiments, the second information comprises a second access code for accessing the second encoding.

[0048] As mentioned above, in embodiments, the system may comprise a control system. The control system may be configured to control the system, especially the light generating device. The term “controlling” and similar terms especially refer at least to determining the behavior or supervising the running of an element. Hence, herein “controlling” and similar terms may e.g. refer to imposing behavior to the element (determining the behavior or supervising the running of an element), etc., such as e.g. measuring, displaying, actuating, opening, shifting, changing temperature, etc.. Beyond that, the term “controlling” and similar terms may additionally include monitoring. Hence, the term “controlling” and similar terms may include imposing behavior on an element and also imposing behavior on an element and monitoring the element. The controlling of the element can be done with a control system. The control system and the element may thus at least temporarily, or permanently, functionally be coupled. The element may comprise the control system. In embodiments, the control system and element may not be physically coupled. Control can be done via wired and / or wireless control. The term “control system” may also refer to a plurality of different control systems, which especially are functionally coupled, and of which e.g. one control system may be a master control system and one or more others may be slave control systems. A control system may comprise or may be functionally coupled to a user interface.

[0049] The control system may also be configured to receive and execute instructions from a remote control. In embodiments, the control system may be controlled via an App on a device, such as a portable device, like a Smartphone or I-phone, a tablet, etc.. The device is thus not necessarily coupled to the (lighting) system, but may be (temporarily) functionally coupled to the system. In particular, in embodiments, the control system may be configured to receive control input, especially control input comprising an access key. Especially, the control system may be configured to control (a lighting parameter of) the light generating device based on the control input comprising the access key, i.e., the access key may facilitate adjusting operational settings of the control system (and thus of the light generating device).

[0050] For instance, in embodiments, the control system may be configured to control an operational parameter of the system, especially of the light generating device, based on the control input. The operational parameter may, for instance, be selected from the group comprising a lumen setting (or “brightness setting"), a dimming profile, a time profile, a color profile, a light distribution setting, such as a beam width and a beam direction, and a sensor input response, such as a programmed response to ambient light level or movement.

[0051] In further embodiments, the control system may be configured to control driver settings based on the control input comprising the access key.

[0052] In further embodiments, the third part (of the system information) may comprise the access key.

[0053] Hence, in specific embodiments, the system comprises a control system, wherein the control system is configured to control the light generating device, wherein the control system is configured to receive control input comprising an access key, wherein the third part comprises (system information comprising) the access key, wherein the control system is configured to control (a lighting parameter of) the light generating device based on the control input comprising the access key.

[0054] Hence, in embodiments the control system may (also) be configured to be controlled by an App on a remote device. In such embodiments the control system of the lighting system may be a slave control system or control in a slave mode. For instance, the lighting system may be identifiable with a code, especially a unique code for the respective lighting system. The control system of the lighting system may be configured to be controlled by an external control system which has access to the lighting system on the basis of knowledge (input by a user interface of with an optical sensor (e.g. QR code reader) of the (unique) code. The lighting system may also comprise means for communicating with other systems or devices, such as on the basis of Bluetooth, Thread, WIFI, LiFi, ZigBee, BLE or WiMAX, or another wireless technology.

[0055] Hence, in embodiments, the control system may control in dependence of one or more of an input signal of a user interface, a sensor signal (of a sensor), and a timer. The term “timer” may refer to a clock and / or a predetermined time scheme.

[0056] In further embodiments, the control system may be configured to control a group of light generating devices (comprised by the light generating system). In such embodiments, the control system may be configured to control group membership of the group based on the control input, especially based on the control input comprising an access key. For instance, the control system may be configured to control a group of light generating devices in a building, such as in an office building or a hotel, and newly installed light generating devices may be added to the group via control input comprising an access key. For instance, in embodiments, the first location may be arranged on the control system and the second location may be arranged on a (to-be-added) light generating device or its packaging, especially on the light generating device, or especially on the packaging of the light generating device.

[0057] As described above, the first location and the second location may be spatially separated. The first location may especially comprise (part of) a first surface, wherein the first optical pattern is arranged on the first surface. Similarly, the second location may especially comprise (part of) a second surface, wherein the second optical pattern is arranged on the second surface. The phrase “arranged on a surface” in the context of an optical pattern may herein also refer to an optical pattern being embedded in the surface, such as via etching. The first surface and the second surface may especially be different surfaces of the system, e.g., of different system components, or of different sides of a system component. For instance, in embodiments, the first location and the second location may both be arranged on the light generating device. Especially, in embodiments, the first location may comprise (part of) a first surface of the light generating device and the second location may comprise (part of) a second surface of the light generating device.

[0058] Further, the first surface and the second surface may, for instance, comprise packaging material, a sticker (e.g., with a QR code), a piece of metal, or a piece of plastic.

[0059] In particular, in embodiments, the system may comprise a compartment, especially a closed compartment, wherein the first location is arranged external to the compartment, and wherein the second location is arranged inside of the compartment. Especially, the second optical pattern may be arranged on a (second) surface on the inside of the compartment. In such embodiments, the second information may especially comprise at least some system information, such as access information, not comprised by the first information.

[0060] For instance, in the context of a lighting pole, the first location may be arranged on the pole and may be relatively easily accessible, whereas the second location may be arranged inside of an internal compartment of the light generating device and may only be accessible by opening up and / or partially dismantling the light generating device, e.g., in the context of maintenance activities. As a further example, the second location, e.g., comprising a QR code, can be placed inside the lighting pole behind a (small) panel (or “door”). Another system architecture is combining streetlights with a cabinet in the street which switches the whole street on / off (or dims the light of all poles in the street). The second optical pattern can also be placed in this cabinet which is typically sealed and not easily accessible. Such optical pattern may also provide more sensitive (second) information regarding the system, e.g., the complete street installation.

[0061] In particular, in embodiments, the system may comprise a lighting pole, wherein the lighting pole, especially an elongated pole element of the lighting pole, defines an axis of elongation A (of the light generating device), and wherein along the axis of elongation A the first location and the second location may be separated by an (edge-to-edge) distance dl. Generally, the axis of elongation A may be perpendicular to a ground surface. In embodiments, the distance dl may be at least 0.5m, such as at least Im, especially at least 2m. In further embodiments, the distance dl may be at most 14m, such as at most 12m, especially at most 8m.

[0062] The lighting pole may especially have a height H selected from the range of 0.5 - 15m, such as from the range of 1 - 12m, especially from the range of 2 - 9m. In further embodiments, dl may be selected from the range of 0.1 *H - 0.99*H, such as from the range of 0.2*H - 0.9*H. The height H may especially be defined parallel to the axis of elongation A. Further, the height H may especially be measured from ground level.

[0063] In further embodiments, the system, especially a street lighting system, may comprise a lighting pole, wherein the lighting pole comprises a device support section, a base, and the (elongated) pole element. The device support section may be configured to support the light generating device. The base may be configured to structurally support the lighting pole (especially the pole element). For instance, the base may be configured to be partially inserted into the ground.

[0064] In further embodiments, the first optical pattern may be arranged on an external surface of the base, and the first optical pattern and the second optical pattern may be physically separated by a distance dl, wherein dl > 0.3*H, especially > 0.5*H, such as > 0.7*H, especially > 0.8*H.

[0065] In particular, in embodiments, the first location may be arranged closer to a base of the pole than the second location.

[0066] In further embodiments, the first location may be an externally accessible location. Especially, the first location may be an external surface of a system component of the system, especially of the light generating device.

[0067] In further embodiments, as indicated above, the system may comprise a compartment, wherein the compartment may comprise an internal compartment of the light generating device, and wherein the second location may be arranged in the internal compartment. In further embodiments, the light generating device may comprise closing means configured to close the internal compartment, especially wherein the closing means comprise one or more of a seal, a lock, a (threaded) fastener, and glue.

[0068] Alternatively, the compartment may be defined by packaging, i.e., the system may comprise packaging, such as a box, wherein the packaging comprises (or “defines”) the compartment. For instance, in embodiments, the system may comprise a (closeable) compartment, wherein the first location is arranged external to the compartment, and wherein the second location is arranged inside of the compartment, wherein the system comprises packaging, wherein the packaging defines the compartment.
