The camera module (160) is directed toward a refrigeration compartment to capture images thereof when in the extended position.

Description

Technical Field

[0001] The present invention relates generally to refrigeration appliances, and more specifically to a refrigeration appliance having one or more cameras for capturing an image or video of a portion thereof. Background Technology

[0002] Storage compartments, such as those in refrigeration appliances and cabinets, typically provide enclosed chambers for receiving multiple items or objects. For example, refrigeration appliances often include a housing that defines a refrigerated compartment. Users can place food or objects inside the refrigerated compartment to prevent spoilage. This increases the usable lifespan of perishable items.

[0003] Over time, a large amount of stored items (e.g., food) may accumulate in the refrigerator's freezer compartment. As the stored items accumulate, users of the refrigerated appliance may find it difficult to see or identify the items inside. Additionally, users may have difficulty determining the quantity of certain items within the appliance. This is especially true when multiple users add / remove items from a shared refrigerated appliance without communicating with other users. Consequently, users may unintentionally purchase too many or unnecessary items. For example, some foods are not easily perishable in the freezer compartment and may not be consumed frequently. Therefore, these foods can remain in the freezer compartment for a longer period. Users may forget about these foods and purchase substitutes even when they have acceptable alternatives, resulting in inconvenience or unnecessary spending. Alternatively, some users may not be aware that certain items have been removed or consumed. Consequently, users may not be able to replace or replenish these items.

[0004] Some existing appliances have attempted to address some of these problems by installing cameras inside the refrigeration room to capture images of the refrigeration space. However, such appliances may still struggle to capture useful images, especially for items placed on lower shelves, under other items, or where there are other items between the camera and the stored items.

[0005] Therefore, a refrigeration appliance having features for assisting users in capturing, viewing, or tracking the contents of the refrigeration compartment would be useful. In particular, it would be advantageous to provide a refrigeration appliance with improved features for capturing images of items placed inside or removed from the refrigeration compartment. Summary of the Invention

[0006] Various aspects and advantages of the present invention will be set forth in the description which follows, or will be apparent from the description, or may be learned by practicing the invention.

[0007] In one exemplary aspect of the invention, a refrigeration appliance is provided. The refrigeration appliance may include a housing, a door, a shelf, and a camera module. The housing may define a refrigeration compartment. The door may be rotatably hinged to the housing to provide selective access to the refrigeration compartment. The shelf may be mounted inside the refrigeration compartment. The shelf may extend laterally between a front edge near the door and a rear edge away from the door. The camera module may be movably mounted to the housing above the shelf. The camera module may move along a predetermined direction on the housing between a retracted position near a first end of the housing and an extended position near a second end of the housing. In the extended position, the camera module may be pointed at the refrigeration compartment to capture its image. In the extended position, the camera module may be laterally positioned between the front edges of the door and the shelf.

[0008] In another exemplary aspect of the invention, a cooling appliance is provided. The cooling appliance may include a housing, a door, a camera bracket, a camera module, and a light source. The housing may define a cooling chamber. The door may be rotatably hinged to the housing to provide selective access to the cooling chamber. The camera bracket may be movably mounted to the housing. The camera bracket may move along a predetermined direction on the housing between a retracted position near a first end of the housing and an extended position near a second end of the housing. The camera module may be supported on the camera bracket to move together with the camera bracket between the retracted and extended positions, the camera module being pointed at the cooling chamber in the extended position to capture an image of the cooling chamber. The light source may be supported on the camera bracket to move together with the camera bracket between the retracted and extended positions. The light source, in the extended position, may be pointed at the cooling chamber to illuminate the cooling chamber.

[0027] Referring now to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is given by way of explanation and does not constitute a limitation thereof. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the invention without departing from its scope. For example, features shown or described as part of one embodiment can be used in another embodiment, thereby producing yet another embodiment. Therefore, it is desired that the invention cover such modifications and variations falling within the scope of the appended claims and their equivalents.

[0028] As used herein, the term “or” is generally intended to be inclusive (i.e., “A or B” is intended to mean “A or B or both”). The terms “first,” “second,” and “third” are used interchangeably to distinguish one component from another, and these terms are not intended to indicate the location or importance of individual components.

[0029] Now turn to the attached diagram. Figure 1 A front elevation view of a refrigeration appliance 100 according to an exemplary embodiment of the present invention is provided, wherein the refrigerator door 128 of the refrigeration appliance 100 is shown in the closed position. Figure 2 A front elevation view of the refrigeration appliance 100 is provided, in which the refrigerator door 128 is shown in the open position to expose the food preservation compartment 122 of the refrigeration appliance 100.

[0030] The refrigeration appliance 100 includes a housing or enclosure 120 extending along a vertical direction V between a top 101 and a bottom 102. The enclosure 120 also extends along a lateral direction L between a first side 105 and a second side 106, and along a transverse direction T between a front end 103 and a rear end 104. Each of the vertical direction V, the lateral direction L, and the transverse direction T is perpendicular to each other to define an orthogonal directional system.

[0031] The cabinet 120 defines a refrigerated compartment for receiving and storing food. Specifically, the cabinet 120 defines a food preservation compartment 122 disposed at or adjacent to the top 101 of the cabinet 120 and a freezer compartment 124 disposed at or adjacent to the bottom 102 of the cabinet 120. Thus, the refrigeration appliance 100 is generally referred to as a bottom-mounted refrigerator. However, it is recognized that the benefits of the invention apply to other types and styles of refrigeration appliances, such as top-mounted refrigeration appliances, side-by-side refrigeration appliances, etc. Therefore, the description set forth herein is for illustrative purposes only and is not intended to limit any particular storage enclosure or refrigerator compartment configuration in any way, unless otherwise indicated.

[0032] The refrigerator door 128 is rotatably hinged to the edge of the cabinet 120 for selective access to the food preservation compartment 122. Additionally, a freezer door 130 is arranged below the refrigerator door 128 for selective access to the freezer compartment 124. The freezer door 130 is connected to a freezer drawer 142 (not shown) that is slidably mounted within the freezer compartment 124. As described above, the refrigerator door 128 and the freezer door 130... Figure 1 The refrigerator door 128 is shown in the closed position. Figure 2 The middle is shown as being in the open position.

[0033] exist Figure 1 and Figure 2 In an exemplary embodiment, the refrigerator door 128 is arranged in a French door configuration. Thus, the refrigerator door 128 may include a pair of independently movable refrigerator door sections 128 (i.e., door sections 128) pivoting at opposite sides of the housing 120. In other words, the first door section 128 is pivotally mounted to a first side 105, while the second door section 128 is pivotally mounted to a second side 106, to move or pivot independently of the first door section 128.

[0034] Turn now Figure 2 As those skilled in the art will understand, various storage components are installed within the food preservation compartment 122 to facilitate the storage of food therein. Specifically, the storage components include a housing 140, a drawer 142, and a shelf 144 installed within the food preservation compartment 122. The housing 140, drawer 142, and shelf 144 are configured to receive stored items (e.g., beverages or solid foods) and can help organize such foods. As an example, drawer 142 can receive fresh foods (e.g., vegetables, fruits, or cheese) and increase the shelf life of such fresh foods.

[0035] The refrigeration appliance 100 also includes features to assist the user in identifying food located in the food preservation compartment 122 or the freezer compartment 124. The user can utilize these features, for example, to view the food stored in the food preservation compartment 122 or the freezer compartment 124, or to create an inventory of such food. These features are discussed in more detail below.

[0036] Figure 3 A schematic diagram of a refrigeration appliance 100 is provided. The refrigeration appliance 100 includes a controller 150 operatively connected to or in communication with components of a refrigeration system (not shown) configured to cool a food preservation compartment 122 or a freezer compartment 124. Components include a compressor 170, an evaporator fan 172, and a condenser fan 174. The controller 150 can selectively operate these components to cool the food preservation compartment 122 or the freezer compartment 124. The controller 150 also communicates with a thermostat (e.g., a thermocouple or a thermistor). The thermostat can be located in either the food preservation compartment 122 or the freezer compartment 124. Figure 2 The controller 150 can receive a signal from the thermostat corresponding to the temperature of the food preservation compartment 122 or the freezer compartment 124. The controller 150 may also include an internal timer for calculating the elapsed time period.

[0037] Controller 150 may include memory and one or more microprocessors, such as a general-purpose or special-purpose microprocessor, for executing programming instructions or microcontroller code associated with the operation of the refrigeration appliance 100. The memory may represent random access memory such as DRAM or read-only memory such as ROM or FLASH. In some embodiments, the processor executes permanently programmed instructions stored in the memory. In some embodiments, the instructions include software packages configured to operate the refrigeration appliance 100 or to execute operating routines. The memory may be a separate component from the processor or may be contained on a board within the processor. Alternatively, controller 150 may be constructed to perform control functions without using a microprocessor (e.g., using a combination of discrete analog or digital logic circuits; such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, etc.), rather than relying on software.

[0038] The controller 150 can be located at various locations throughout the refrigeration appliance 100. Input / output (“I / O”) signals can be routed between the controller 150 and various operating components of the refrigeration appliance 100. One or more components of the refrigeration appliance 100 can be operatively communicated with the controller 150 via one or more conductive signal lines or a shared communication bus (e.g., electrical communication). Alternatively or additionally, one or more components of the refrigeration appliance 100 can be operatively communicated with the controller 150 via one or more wireless signal bands (e.g., wireless communication).

[0039] The cooling appliance 100 also includes a camera or camera module 160. The camera 160 can be any type of device suitable for capturing two-dimensional photographs or images, such as... Figure 4 The image shown is an example. As an example, camera 160 may be a video camera or digital camera with an electronic image sensor, such as a charge-coupled device (CCD) or CMOS sensor. When assembled, camera 160 communicates with controller 150 (e.g., electrical or wireless communication) such that controller 150 can receive signals from camera 160 corresponding to the images captured by camera 160.

[0040] As will be described in detail below, camera 160 is mounted to refrigeration appliance 100 and can be pointed at one or more refrigeration compartments (e.g., Figure 2 The food preservation compartment 122 in the food preservation compartment. In some embodiments, the camera 160 is mounted together with the camera assembly 300 within the food preservation compartment 122 and located at the top of the food preservation compartment 122 (e.g., adjacent to the top 101). For example, the camera assembly 300 may be attached to or guided through the top wall defining the inner liner of the food preservation compartment 122. In such embodiments, as Figure 2 As shown, camera 160 can typically point downwards, and during use, camera 160 can point towards drawer 142 and shelf 144. Figure 2 At least a portion of any particular one or combination of the drawers 142, all drawers 142, one or all shelves 144, or any suitable combination thereof. Thus, camera 160 can capture images of one of the drawers 142, all drawers 142, one of the shelves 144, all shelves 144, or any suitable combination thereof.

[0041] In some embodiments, the refrigeration appliance 100 includes an integrated display 180. The integrated display 180 may be mounted on the refrigerator door 128. Figure 1 The integrated display 180 may be located at any other suitable location on the camera 160 or on the refrigeration appliance 100. The integrated display 180 is operatively in communication with the controller 150, such that the integrated display 180 may receive from the controller 150 a signal corresponding to an image captured by the camera 160. The integrated display 180 may receive such a signal from the controller 150 and visually present the image to the user. The integrated display 180 may include, for example, a liquid crystal display panel (LCD), a plasma display panel (PDP), or any other suitable mechanism for displaying images (e.g., a projector).

[0042] In another or alternative embodiment, the refrigeration appliance 100 includes a network interface (not shown) that connects the refrigeration appliance 100 (e.g., controller 150) to a network 190, enabling the refrigeration appliance 100 to transmit and receive information via the network 190. The network 190 can be any wired or wireless network, such as a WAN, LAN, or HAN.

[0043] In some such embodiments, the cooling appliance 100 (e.g., controller 150) communicates with the mobile display 182 via a network 190. The mobile display 182 can be any device configured to communicate via the network 190 and display images received therefrom. For example, the mobile display 182 can be a computer, smartphone, or tablet. The mobile display 182 communicates with the controller 150 such that it can receive signals from the controller 150 (via the network 190) corresponding to a user interface or an image captured by the camera 160. The mobile display 182 can receive such signals from the controller 150 and visually present one or more images to the user. The mobile display 182 may include, for example, a liquid crystal display (LCD), a plasma display panel (PDP), or any other suitable mechanism for displaying images (e.g., a projector). The mobile display 182 may also include an interface (e.g., tactile input, such as buttons, or a graphical user interface) that allows the mobile display 182 to initiate communication with the cooling appliance 100 via the network 190.

[0044] During use, such as during an image capture sequence, camera 160 may capture one or more two-dimensional images (e.g., as a video feed or a series of consecutive still images) that can be transmitted to controller 150 (e.g., as a data signal), as generally understood. Based on the captured images, objects within the field of view of camera 160 (e.g., stored items such as food, or non-stored items such as user limbs, shelves, movable drawers, etc.) can be automatically identified by controller 150. As understood, the identification or authentication of such objects can be performed by edge matching, divide-and-conquer search, grayscale matching, histogram of receptive field response, or another suitable routine (e.g., performed at controller 150 based on one or more images captured from camera 160).

[0045] As an example, Figure 4 Examples of exemplary two-dimensional images, such as those captured at camera 160 as part of an image capture sequence, are given. In other words, Figure 4 The example illustrates the possible field of view of camera 160 pointing towards the cooling room. As an additional or optional example, Figure 5 and Figure 6 Examples are provided for a series of separate exemplary two-dimensional images that can be viewed on displays 180 or 182 after being separated or generated from an initial image captured at camera 160 as part of an image capture sequence.

[0046] In some embodiments, camera 160 and controller 150 are configured to capture multiple, consecutive two-dimensional images (e.g., at a predetermined rate or mode) as part of an image capture sequence. Sequential images (e.g., previously captured images and most recently captured images) may be recorded (e.g., temporarily) and compared at controller 150. Based on the comparison, changes or differences between consecutive images can be detected. In some embodiments, the image capture sequence is prompted or initiated in response to detected movement within a refrigerated compartment (e.g., food preservation compartment 122). Subsequently, the image capture sequence can be stopped or paused based on one or more termination conditions, such as the expiration of a predetermined time period, failure to detect further changes in consecutive images, or closure of door 128.

[0047] As an example, and as Figure 4 As shown, at least a portion of the multiple shelves 144A, 144B, 144C, 144D, and 144E are visible within the field of view of camera 160. Figure 2 For example, when the camera 160 is in the extended position. For instance, the leading edges 210A, 210B, 210C, 210D, and 210E of shelves 144A, 144B, 144C, 144D, and 144E are within the field of view of the camera 160. Figure 2 Each leading edge 210A, 210B, 210C, 210D, 210E can represent the foremost surface of the corresponding shelf 144A, 144B, 144C, 144D, 144E, which can be the shelf surface closest to the opening of the food preservation compartment 122. Figure 4 In the example shown, leading edge 210A corresponds to shelf 144A, leading edge 210B corresponds to shelf 144B, leading edge 210C corresponds to shelf 144C, leading edge 210D corresponds to shelf 144D, and leading edge 210E corresponds to shelf 144E. In some embodiments, one or more of shelves 144A, 144B, 144C, 144D, 144E are positioned at different heights (i.e., relative vertical positions within the food preservation compartment 122). Optionally, the leading edges 210A, 210B, 210C, 210D, 210E of shelves 144A, 144B, 144C, 144D, 144E at independent heights within the food preservation compartment 122 may be within the field of view of camera 160.

[0048] In some implementations, controller 150 is configured to identify reference marks or regions of one or more of shelves 144A, 144B, 144C, 144D, 144E based on signals or images received from camera 160 (e.g., during an image capture sequence). For example, based on a two-dimensional image captured from camera 160, controller 150 may identify reference edges 212A, 212B, 212C, 212D, 212E of one or more of shelves 144A, 144B, 144C, 144D, 144E. Alternatively, corresponding reference edges 212A, 212B, 212C, 212D, 212E may be identified for each shelf 144A, 144B, 144C, 144D, 144E. Reference edges 212A, 212B, 212C, 212D, and 212E can be used together to establish a vertical coordinate system within the food preservation compartment 122. Using this vertical coordinate system, the controller 150 can determine which shelves 144A, 144B, 144C, 144D, and 144E, or between which vertically adjacent shelves 144 (e.g., 144A and 144C), items, or user limbs 214A and 214B (e.g., hands, arms, etc.). As an example, in Figure 4 In the example image, the user's left arm 214A is shown crossing the reference edge 212C, but not the higher reference edge 212A. Therefore, it can be determined that the user's left arm 214A is passing between the shelf 144A and the shelf 144C. As an additional example, in Figure 4 In the example image, the user's right arm 214B is shown crossing the reference edge 212E, but not the higher reference edges 212D and 212B. Therefore, it can be determined that the user's right arm 214B is passing between the shelves 144D and 144E.

[0049] Now generally turning Figures 5 to 16 Detailed description includes installation into refrigeration appliance 100 ( Figure 1 and Figure 2The camera module 310 comprises a camera assembly 300. The camera module 310 may include or be included with a camera 160 (e.g., provided with the camera assembly 300 as described above). Furthermore, at least a portion of the camera assembly 300, including the camera module 310, can move independently between a retracted position and an extended position (e.g., along a predetermined direction) while remaining attached to a portion of the housing 120. Instead, the camera module 310 can be close to a first end of the housing 120 in the retracted position (and thus away from a second end of the housing 120), and away from the first end of the housing 120 in the extended position (and thus close to the second end of the housing 120). Moreover, as described above, in the extended position, the camera module 310 is pointed towards the refrigeration compartment (e.g., the food preservation compartment 122) to capture one or more images. Optionally, the camera module 310 can capture images while moving between the retracted and extended positions, which is advantageous for capturing a larger visible area or field of view (e.g., compared to a stationary camera).

[0050] Special steering Figures 5 to 7 In some embodiments, a portion of the camera assembly 300, including the camera module 310, may be movable along a lateral T (e.g., driven by a mechanical drive assembly 318). In other words, the predetermined direction of movement may include or be provided as a lateral T. From the retracted position (e.g., Figure 6 ) to the extended position (e.g., Figure 7 The movement of the camera module 310 can bring it closer to the user in front of the housing 120. Thus, the extended position may include the camera module 310 near the front end 103 (e.g., the second end), while the retracted position includes the camera module 310 near the rear end 104 (e.g., the first end).

[0051] In some embodiments, the camera module 310 is supported on a camera bracket 312, which is movably mounted to the housing 120 as part of the camera assembly 300. The camera bracket 312 may be anchored or otherwise coupled to the housing 120 (e.g., at a portion of the lining defining the food preservation compartment 122) via an assembly support 314 to move between a retracted position and an extended position. As will be understood, the assembly support 314 may be fixed relative to the housing 120 (e.g., via one or more suitable adhesives, mechanical fasteners, etc.). However, when assembled, the camera module 310 may be fixed relative to the camera bracket 312, thereby allowing it to move in series with the camera bracket 312 along the lateral direction T.

[0052] In alternative embodiments, one or more other functional components besides camera module 310 may be supported on camera bracket 312. For example, light source 316 may be supported on camera bracket 312 to move between a retracted position and an extended position. In some such embodiments, light source 316 is horizontally (e.g., laterally or transversely) spaced from camera module 310. Typically, light source 316 may be provided as any suitable (e.g., electrically powered) light emitter, such as an incandescent bulb, halogen bulb, fluorescent bulb, light-emitting diode (LED), etc. When activated (e.g., in the extended position), light source 316 may illuminate at least a portion of the refrigeration compartment (e.g., food preservation compartment 122). In some embodiments, light source 316 is pointed towards the refrigeration compartment in the extended position. For example, the extended position may include light source 316 pointing towards the refrigeration compartment to illuminate it. Advantageously, light source 316 may typically be pointed towards the same area as camera module 310, thereby providing illumination to improve the accuracy or quality of images captured at camera module 310. In an alternative implementation, light source 316 provides main lighting for the cooling room (e.g., instead of a separate stationary light source installed in the cooling room or connected in series with it).

[0053] Typically, the camera assembly 300 (including camera module 310, camera bracket 312, or assembly support 314) can be positioned at any suitable location on the housing 120 in its extended position to capture images of the refrigerated compartment (e.g., food preservation compartment 122). In an exemplary embodiment, the camera assembly 300 is mounted on top of the housing 120 inside the refrigerated compartment. For example, the camera assembly 300 may be attached to the top wall of the lining (e.g., at the assembly support 314 at top 101).

[0054] In some embodiments, the camera assembly 300 is mounted such that the camera module 310 is movable in front of the leading edge 210 (e.g., a reference edge) of one or more shelves 144 installed within a refrigerated compartment (e.g., food preservation compartment 122). In other words, the camera module 310 in the extended position can be positioned forward from the leading edge 210 of one or more shelves 144 relative to the lateral direction T. For example, in the extended position, the camera module 310 may be positioned between the leading edge 210 and an opening leading to the food preservation compartment 122 or door 128. Additionally or alternatively, the camera module 310 may be positioned forward from the opening in the extended position. The one or more shelves 144 may include the shelf 144 closest to the camera assembly 300 relative to the vertical direction V (e.g., the uppermost shelf) or two or more shelves 144 (e.g., above drawer 142). Advantageously, the extended position allows the camera module 310 to remain visible with a substantial portion of the lower shelf 144 or drawer 142 in sight. Alternatively, the retracted position may provide the camera module 310 behind the front edge 210 of one or more shelves 144 (e.g., along the transverse T between the front edge 210 and the rear end 104).

[0055] Temporarily transferred to Figure 10 While some embodiments may provide the camera assembly 300, and particularly the camera module 310, within a refrigerated compartment (e.g., food preservation compartment 122), other embodiments may provide the camera module 310 outside the corresponding refrigerated compartment (e.g., food preservation compartment 122). Specifically, the camera module 310 may remain away from the refrigerated compartment in both the extended and retracted positions. For example, a camera bracket 312 may be mounted above the refrigerated compartment (e.g., to a portion of the housing 120 away from the lining (such as the outer panel)) to extend in the extended position in front of the opening of the refrigerated compartment.

[0056] Generally return to Figures 5 to 7 and Figure 10The camera assembly 300 may include a drive assembly 318 configured to push or bias the camera bracket 312 to an extended position. In the illustrated embodiment, the drive assembly 318 includes a guide rail 320 and a tip 322 in mechanical communication with the camera bracket 312. As shown, the tip 322 may extend from the camera bracket 312 (e.g., detachably or integrally) and selectively engage with the inner surface of the door 128 to force the camera bracket 312 rearward (e.g., when the door 128 is closed) and hold the camera bracket 312 in a retracted position when the door 128 is in the closed position. Optionally, a spring 324 (e.g., a coil spring, leaf spring, pneumatic cylinder, etc.) may be configured to further mechanically communicate with the camera bracket 312. Specifically, the spring 324 may bias-engage with the camera bracket 312 (including the camera module 310) to bias the camera module 310 to an extended position.

[0057] As shown in the figure, the position of the camera bracket 312 can be based on or correspond to the position of at least one door 128. For example, the retracted position can correspond to the closed position of the matching door 128, while the extended position can correspond to the open position (or at least the partially open or non-closed position) of the matching door 128.

[0058] Note that although linear guide 320 and tip 322 are exemplified, another suitable mechanical drive system (e.g., gear train) may be provided to push camera bracket 312 between the extended and retracted positions based on the position of the matching door 128.

[0059] Turn now Figure 5 and Figure 8 as well as Figure 15 and Figure 16 In some embodiments, a portion of the camera assembly 300, including the camera module 310, is movable along a lateral direction T (e.g., driven by an electronically driven component 318). In other words, the predetermined direction of movement may include or be provided as a lateral direction T. Movement from a retracted position to an extended position may bring the camera module 310 closer to the user in front of the housing 120. Thus, the extended position may include the camera module 310 near the front end 103 (e.g., the second end), while the retracted position includes the camera module 310 near the rear end 104 (e.g., the first end).

[0060] In some embodiments, the camera module 310 is supported on a camera bracket 312, which is movably mounted to the housing 120 as part of the camera assembly 300. The camera bracket 312 may be anchored or otherwise connected to the housing 120 via an assembly support 314 (e.g., at a portion of the lining defining the cooling compartment) to move between a retracted position and an extended position. It is understood that the assembly support 314 may be fixed relative to the housing 120 (e.g., via one or more suitable adhesives, mechanical fasteners, etc.). However, when assembled, the camera module 310 may be fixed relative to the camera bracket 312, thereby allowing it to move in series with the camera bracket 312 along the lateral direction T.

[0061] In alternative embodiments, one or more other functional components besides camera module 310 may be supported on camera bracket 312. For example, light source 316 may be supported on camera bracket 312 to move between a retracted position and an extended position. In some such embodiments, light source 316 is horizontally (e.g., laterally or transversely) spaced from camera module 310. Typically, light source 316 can be provided as any suitable (e.g., electrically powered) light emitter, such as an incandescent bulb, halogen bulb, fluorescent bulb, light-emitting diode (LED), etc. When activated (e.g., in the extended position), light source 316 can illuminate at least a portion of the cooling chamber. In some embodiments, light source 316 is pointed towards the cooling chamber in the extended position. For example, the extended position may include light source 316 pointing towards the cooling chamber to illuminate it. Advantageously, light source 316 may typically be pointed towards the same area as camera module 310, thereby providing illumination to improve the accuracy or quality of images captured at camera module 310. In an alternative implementation, light source 316 provides main lighting for the cooling room (e.g., instead of a separate stationary light source installed in the cooling room or connected in series with it).

[0062] Typically, the camera assembly 300 (including camera module 310, camera bracket 312, or assembly support 314) can be positioned at any suitable location on the housing 120 in its extended position to capture images of the cooling room. In an exemplary embodiment, the camera assembly 300 is mounted on top of the housing 120 inside the cooling room. For example, the camera assembly 300 can be attached to the top wall of the liner (e.g., at the assembly support 314 at top 101).

[0063] In some embodiments, the camera assembly 300 is mounted such that the camera module 310 is movable in front of the leading edge 210 (e.g., a reference edge) of one or more shelves 144 mounted in the refrigeration room. In other words, the camera module 310 in the extended position can be forward from the leading edge 210 of one or more shelves 144 relative to the lateral direction T. For example, in the extended position, the camera module 310 may be positioned between the leading edge 210 and an opening or door 128. Additionally or alternatively, the camera module 310 may be positioned forward from an opening in the extended position. The one or more shelves 144 may include the shelf 144 closest to the camera assembly 300 relative to the vertical direction V (e.g., the uppermost shelf) or two or more shelves 144 (e.g., above drawer 142). Advantageously, the extended position allows the camera module 310 to remain visible with a considerable portion of the lower shelf 144 or drawer 142 in sight. Alternatively, the retracted position may provide the camera module 310 behind the front edge 210 of one or more shelves 144 (e.g., along the transverse T between the front edge 210 and the rear end 104).

[0064] As shown in the figure, the electronic drive assembly 318 can be configured to push or guide the camera bracket 312 to an extended or retracted position. Typically, the electronic drive assembly 318 includes an electronic drive motor 326 mechanically connected to the camera bracket 312. Thus, the electronic drive motor 326 can guide the camera module 310 between the extended and retracted positions. Furthermore, the electronic drive motor 326 can be operatively coupled to the controller 150. Figure 3 (e.g., to send / receive signals therebetween). During use, the electronic drive assembly 318 may receive one or more signals (e.g., from the controller 150) based on the position of one or more doors 128. For example, as generally understood, the controller 150 may be operatively coupled to one or more sensors (e.g., proximity sensors, position sensors, etc.) configured to detect the position of one or more doors 128, such as when the doors 128 are in the closed position. Based on the detected position of one or more doors 128, the controller 150 may send a signal to the electronic drive motor 326 to guide the camera bracket 312 to an extended or retracted position. The position of the camera bracket 312 may be based on or correspond to the position of at least one door 128. For example, the retracted position may correspond to the closed position of the matched door 128, while the extended position may correspond to the open position (or at least a partially open or non-closed position) of the matched door 128. Thus, the electronic drive motor 326 can be configured to push the camera module 310 between the retracted position and the extended position based on received input signals (such as input signals received from sensors configured to detect the position of one or more door panels 128).

[0065] Note that although linear racks and pinions are exemplified, another suitable electric drive system (e.g., a gear train) coupled to the electric drive motor 326 can be provided to push the camera bracket 312 between the extended and retracted positions based on the position of the matched door 128 (e.g., as indicated by a signal received at the electric drive motor 326 via the controller 150).

[0066] Now, a special shift Figure 9 In some embodiments, a portion of the camera assembly 300, including the camera module 310, may be movable laterally along a direction L (e.g., driven by an electronically driven component 318). In other words, the predetermined direction of movement may include or be provided as lateral L. Movement from a retracted position to an extended position may bring the camera module 310 closer to one side of the housing 120 within the refrigeration compartment. For example, the extended position may include the camera module 310 near a first side 105 (e.g., the second end), while the retracted position includes the camera module 310 near a second side 106 (e.g., the first end).

[0067] In some embodiments, the camera module 310 is supported on a camera bracket 312, which is movably mounted to the housing 120 as part of the camera assembly 300. The camera bracket 312 may be anchored or otherwise connected to the housing 120 via an assembly support 314 (e.g., at a portion of the lining defining the cooling compartment) to move between a retracted position and an extended position. As will be understood, the assembly support 314 may be fixed relative to the housing 120 (e.g., via one or more suitable adhesives, mechanical fasteners, etc.). However, when assembled, the camera module 310 may be fixed relative to the camera bracket 312, thereby allowing it to move in series with the camera bracket 312 along a lateral direction L.

[0068] In alternative embodiments, one or more other functional components besides camera module 310 may be supported on camera bracket 312. For example, light source 316 may be supported on camera bracket 312 to move between a retracted position and an extended position. In some such embodiments, light source 316 is horizontally (e.g., laterally or transversely) spaced from camera module 310. Typically, light source 316 can be provided as any suitable (e.g., electrically powered) light emitter, such as an incandescent bulb, halogen bulb, fluorescent bulb, light-emitting diode (LED), etc. When activated (e.g., in the extended position), light source 316 can illuminate at least a portion of the cooling chamber. In some embodiments, light source 316 is pointed towards the cooling chamber in the extended position. For example, the extended position may include light source 316 pointing towards the cooling chamber to illuminate it. Advantageously, light source 316 may typically be pointed towards the same area as camera module 310, thereby providing illumination to improve the accuracy or quality of images captured at camera module 310. In an alternative implementation, light source 316 provides main lighting for the cooling room (e.g., instead of a separate stationary light source installed in the cooling room or connected in series with it).

[0069] Typically, the camera assembly 300 (including camera module 310, camera bracket 312, or assembly support 314) can be positioned at any suitable location on the housing 120 in its extended position to capture images of the cooling room. In an exemplary embodiment, the camera assembly 300 is mounted on top of the housing 120 inside the cooling room. For example, the camera assembly 300 can be attached to the top wall of the liner (e.g., at the assembly support 314 at top 101).

[0070] In some embodiments, the camera assembly 300 is mounted such that the camera module 310 is held or retained in front of the leading edge 210 (e.g., a reference edge) of one or more shelves 144 mounted in the refrigeration room. In other words, the camera module 310, in both the extended and retracted positions relative to the lateral direction T, can be forward from the leading edge 210 of one or more shelves 144. For example, in the extended position, the camera module 310 may be positioned between the leading edge 210 and the opening or door 128. The one or more shelves 144 may include the shelf 144 closest to the camera assembly 300 relative to the vertical direction V (e.g., the uppermost shelf) or two or more shelves 144 (e.g., above the drawer 142). Advantageously, the camera module 310 may be positioned in a position where a considerable portion of the lower shelf 144 or drawer 142 is visible.

[0071] As shown in the figure, the electronic drive assembly 318 can be configured to push or guide the camera bracket 312 to an extended or retracted position. Typically, the electronic drive assembly 318 includes an electronic drive motor 326 mechanically connected to the camera bracket 312. Thus, the electronic drive motor 326 can guide the camera module 310 between the extended and retracted positions. Furthermore, the electronic drive motor 326 can be operatively coupled to the controller 150. Figure 1 (For example, to send / receive signals therebetween). During use, the electronic drive assembly 318 can receive one or more signals (e.g., from the controller 150) based on the position of one or more doors 128. For example, as generally understood, the controller 150 can be operatively coupled to one or more sensors (e.g., proximity sensors, position sensors, etc.) configured to detect the position of one or more doors 128, such as when the doors 128 are in the closed position. Based on the detected position of one or more doors 128, the controller 150 can send a signal to the electronic drive motor 326 to guide the camera bracket 312 to an extended or retracted position.

[0072] As an example, the electronic drive motor 326 can guide or move the camera bracket 312 to the side of an open door 128. In response to an opening signal received from a sensor configured to detect the position of the door 128 pivotally mounted on the first side 105, the electronic drive motor 326 can guide the camera bracket 312 to a bracket position (e.g., an extended position) near the first side 105. Similarly, in response to an opening signal received from a sensor configured to detect the position of the door 128 pivotally mounted on the second side 106, the electronic drive motor 326 can guide the camera bracket 312 to a bracket position (e.g., a retracted position) near the second side 106. Optionally, the electronic drive motor 326 may guide the camera bracket 312 to an intermediate position between an extended position and a retracted position in response to receiving an opening signal from both a sensor configured to detect the position of the door 128 pivotally mounted on the first side 105 and a sensor configured to detect the position of the door 128 pivotally mounted on the second side 106. Alternatively, opening both doors 128 may guide the camera bracket 312 to the intermediate position.

[0073] Thus, the electronic drive motor 326 can be configured to actuate the camera module 310 between a retracted position and an extended position based on an input signal corresponding to the pivoting position of a pair of independent movable door bodies 128. The position of the camera bracket 312 can be based on or correspond to the position of at least the door bodies 128. For example, the retracted position may correspond to the open position (or at least a partially open or unclosed position) of one of the door bodies 128, while the extended position may correspond to the open position (or at least a partially open or unclosed position) of the other door body 128 in the pair. Optionally, an intermediate position may correspond to the simultaneous open position (or at least a partially open or unclosed position) of both door bodies 128 in the pair.

[0074] Note that although linear racks and pinions are exemplified, another suitable electric drive system (e.g., a gear train) coupled to the electric drive motor 326 can be provided to push the camera bracket 312 between the extended and retracted positions based on the position of the door 128 (e.g., as indicated by a signal received at the electric drive motor 326).

[0075] Turn now Figure 5 and Figure 11 as well as Figure 14 In some embodiments, a portion of the camera assembly 300, including the camera module 310, may be at least partially movable along a lateral direction T (e.g., driven by a mechanical drive assembly 318). In other words, the predetermined direction of movement may include the lateral direction T. From the retracted position (e.g., Figure 13 ) to the extended position (e.g., Figure 14 The movement of the camera module 310 can bring it closer to the user in front of the housing 120. Thus, the extended position may include the camera module 310 near the front end 103 (e.g., the second end), while the retracted position includes the camera module 310 near the rear end 104 (e.g., the first end).

[0076] In some embodiments, the camera module 310 is supported on a camera bracket 312, which is movably (e.g., pivotally) mounted to the housing 120 as part of the camera assembly 300. The camera bracket 312 may be anchored or otherwise connected to the housing 120 via an assembly support 314 (e.g., at a portion of the lining defining the cooling compartment) to move between a retracted and extended position. Optionally, one or more pivot arms 328 may connect the camera bracket 312 to the assembly support 314. As will be understood, the assembly support 314 may be fixed relative to the housing 120 (e.g., via one or more suitable adhesives, mechanical fasteners, etc.). However, when assembled, the camera module 310 may be fixed relative to the camera bracket 312, thereby allowing it to move in series with the camera bracket 312 along a transverse direction T. For example, at least a portion of the camera module 310 may be accommodated within a module slot defined within the camera bracket 312.

[0077] In alternative embodiments, one or more other functional components besides camera module 310 may be supported on camera bracket 312. For example, light source 316 may be supported on camera bracket 312 to move between a retracted position and an extended position. In some such embodiments, light source 316 is horizontally (e.g., laterally or transversely) spaced from camera module 310. Typically, light source 316 can be provided as any suitable (e.g., electrically powered) light emitter, such as an incandescent bulb, halogen bulb, fluorescent bulb, light-emitting diode (LED), etc. When activated (e.g., in the extended position), light source 316 can illuminate at least a portion of the cooling chamber. In some embodiments, light source 316 is pointed towards the cooling chamber in the extended position. For example, the extended position may include light source 316 pointing towards the cooling chamber to illuminate it. Advantageously, light source 316 may typically be pointed towards the same area as camera module 310, thereby providing illumination to improve the accuracy or quality of images captured at camera module 310. In an alternative implementation, light source 316 provides main lighting for the cooling room (e.g., instead of a separate stationary light source installed in the cooling room or connected in series with it).

[0078] Typically, the camera assembly 300 (including camera module 310, camera bracket 312, or assembly support 314) can be positioned at any suitable location on the housing 120 in its extended position to capture images of the cooling room. In an exemplary embodiment, the camera assembly 300 is mounted on top of the housing 120 inside the cooling room. For example, the camera assembly 300 can be attached to the top wall of the liner (e.g., at the assembly support 314 at top 101).

[0079] In some embodiments, the camera assembly 300 is mounted such that the camera module 310 can pivot and move forward of the leading edge 210 (e.g., a reference edge) of one or more shelves 144 mounted in the refrigeration room. In other words, the camera module 310 in the extended position can be forward from the leading edge 210 of one or more shelves 144 relative to the lateral direction T. For example, in the extended position, the camera module 310 can be positioned between the leading edge 210 and an opening or door 128. Additionally or alternatively, the camera module 310 can be positioned forward from an opening in the extended position. The one or more shelves 144 may include the shelf 144 closest to the camera assembly 300 relative to the vertical direction V (e.g., the uppermost shelf) or two or more shelves 144 (e.g., above drawer 142). Advantageously, the extended position allows the camera module 310 to remain visible with a considerable portion of the lower shelf 144 or drawer 142 in sight. Alternatively, the retracted position may provide the camera module 310 behind the front edge 210 of one or more shelves 144 (e.g., along the transverse T between the front edge 210 and the rear end 104).

[0080] In an exemplary embodiment, the angle of the camera module 310 (e.g., the direction of the line of sight relative to a fixed direction) changes between a retracted position and an extended position. Thus, one or both of the retracted and extended positions may not be parallel to a fixed direction (e.g., vertical V). As an example, the camera module 310 may point forward in the retracted position (e.g., typically towards the opening of a cooling room or door 128). Figure 13 As shown, relative to the vertical V, the line of sight of camera module 310 can be defined at an acute, non-parallel angle (e.g., forward along the horizontal T). As an additional or optional example, camera module 310 can be pointed rearward (e.g., typically away from door 128 or towards the rear end 104). Figure 14 As shown, relative to the vertical V, the line of sight of camera module 310 can be defined by an acute angle that is not parallel, which is different from the angle defined in the retracted position (e.g., backward along the horizontal T).

[0081] Camera assembly 300 may include a drive assembly 318 configured to push or bias camera bracket 312 to an extended position. As shown, a pair of pivot arms 328, each with an independent arm length and laterally spaced on camera bracket 312, connected to camera bracket 312 at points, can be used to change the angle defined by line of sight (e.g., relative to vertical V) between a retracted and extended position. Optionally, camera bracket 312 may selectively engage with the inner surface of door 128 to force camera bracket 312 rearward (e.g., when door 128 is closed) and hold camera bracket 312 in the retracted position when door 128 is in the closed position. Optionally, a spring (not shown—e.g., a coil spring, leaf spring, pneumatic cylinder, etc.) may be configured to further mechanically communicate with camera bracket 312. Specifically, the spring may bias-engage with camera bracket 312 (including camera module 310), which biases camera module 310 to an extended position.

[0082] As shown in the figure, the position of the camera bracket 312 can be based on or correspond to the position of at least one door 128. For example, the retracted position can correspond to the closed position of the matching door 128, while the extended position can correspond to the open position (or at least the partially open or non-closed position) of the matching door 128.
