Description

Technical Field

[0001] This invention relates to seat assemblies and passenger seat devices. Background Technology

[0002] Seat units, such as those for aircraft, can be configured as seat assemblies (e.g., aircraft seat assemblies) and have passenger seating arrangements for vehicle compartments (e.g., aircraft cabins). Known seat assemblies typically include a base structure (such as a frame structure) to support cushions. These cushions can be detachably attached to the base structure.

[0003] However, known seat components are not easily reconfigured and often must be replaced for different purposes. For example, when changing from a passenger seat configuration to a utility element configuration, the known seat components must be completely disassembled to be interchanged with the passenger seat, for example, the utility element. Therefore, reconfiguring or changing a seat for a different purpose using known seat components can be time-consuming and expensive. Summary of the Invention

[0004] In one aspect, a seat assembly includes: a base structure having at least one of a seatpan shell and a backrest shell; and one or more attachment structures configured to removably connect at least one of the seatpan shell and the backrest shell to a seat surface device or a utility surface device. Based on connecting the seat surface device or utility surface device to the base structure, the base structure is convertible between a passenger seat and a utility element.

[0005] On the other hand, a passenger seating arrangement for a vehicle compartment includes a first passenger seat and a seat assembly, wherein the first passenger seat is arranged laterally adjacent to the seat assembly. The seat assembly includes: a base structure having at least one of a seat panel housing and a backrest housing; and one or more attachment structures configured to removably connect at least one of the seat panel housing and the backrest housing to a seat surface device or a utility surface device. Based on connecting the seat surface device or utility surface device to the base structure respectively, the base structure is convertible between a passenger seat and a utility element.

[0006] In another aspect, an aircraft seating arrangement includes a first passenger seat, a second passenger seat, and a third passenger seat, wherein the third passenger seat is located between the first and second passenger seats and together defines a seat row. At least one of the first, second, and third passenger seats includes a seat assembly. The seat assembly includes: a base structure having at least one of a seat panel housing and a backrest housing; and one or more attachment structures configured to removably connect at least one of the seat panel housing and the backrest housing to a seat surface device or a utility surface device. Based on connecting the seat surface device or utility surface device to the base structure respectively, the base structure is convertible between a passenger seat arrangement and a utility element.

[0017] The foregoing summary of the invention and the specific embodiments of certain examples and implementations described below will be better understood when read in conjunction with the accompanying drawings. As used herein, elements or steps stated in the singular and in the prior words “a” or “an” should be understood to not necessarily exclude multiple elements or steps. Furthermore, references to “an embodiment,” “an implementation,” or “an example” are not intended to exclude the existence of other embodiments, implementations, or examples that also include the stated features. Moreover, unless explicitly stated otherwise, embodiments, implementations, or examples that “comprise” or “have” one or more elements having a specific characteristic may include other elements that do not have that characteristic.

[0018] Although various spatial and directional terms, such as “top,” “bottom,” “upper,” “lower,” and “vertical,” are used to describe examples, it should be understood that these terms are used only relative to the orientation shown in the accompanying drawings. These orientations may be reversed, rotated, or otherwise changed such that if the structure is flipped 180 degrees, the top side becomes the bottom side, and if the structure is pivoted 90 degrees, it becomes the left or right side, etc.

[0019] Some implementations provide an improved seating assembly that can be converted, for example, between a passenger seat and a utility component. For instance, a single seating assembly can be used for different purposes and avoids the complete removal of the passenger seat to interchange it with the utility component. Thus, improved passenger seating arrangements for vehicle cabins result in multiple instances, such as those for aircraft cabins with seating assemblies. It should be noted that while multiple instances are described in an aircraft environment, one or more instances described herein can be implemented in non-aircraft environments, such as seats in other vehicles.

[0020] One or more implementations include a seat assembly with a passenger seat device configured for easy conversion. For example, the seat assembly (specifically an aircraft seat assembly) includes at least a base structure having at least one of a seat panel housing and a backrest housing, a seat surface device, and a utility surface device. In various implementations, the base structure includes an attachment structure for receiving a corresponding attachment structure for the seat cushion device or utility surface device, wherein the base structure is convertible into a passenger seat and utility element depending on the surface device being detachably attached to the base structure, as described in more detail herein.

[0021] For example, seat assemblies are arranged in the economy class of airlines or aircraft. However, it should be understood that such seat assemblies can be arranged in any passenger transport vehicle (such as buses, trains, etc.). One or more examples include seat assemblies used in commercial passenger transport vehicles that appear in many different configurations. However, with the implementations described herein, seat assemblies do not need to be removed when not in use and can be converted into non-seat structures, such as utility structures for passengers. That is, various examples provide options and features for converting unused seats into non-seat structures that incorporate useful passenger utility features.

[0022] One or more implementations provide a simple and lightweight seat assembly with easily interchangeable features, transforming a passenger seat into a practical passenger element. When the seat assembly is not used as a passenger seat, for example, due to fewer passengers on the flight and / or due to safety reasons such as specific health reasons (e.g., restrictions, social distancing regulations), the seat assembly can be converted into a practical element for another passenger sitting next to it. This improves the passenger experience (e.g., providing a sense of comfort and luxury in economy class, thereby making a private practical surface available for economy class passengers).

[0023] Please refer to the attached diagram for details. Figure 1A A perspective view shows a passenger seating arrangement 100 with multiple adjacent passenger seats 102a, 102b, 102c. It can be seen that the passenger seating arrangement 100 is in a configuration consisting only of passenger seats 102a, 102b, 102c. In one example, passenger seats 102a, 102b, 102c are economy seats. In the illustrated example, passenger seats 102a, 102b, 102c are arranged side-by-side on a base support structure 104. In various embodiments, the base support structure 104 is arranged on the cabin floor of the vehicle compartment. For example, the base support structure 104 is coupled to or forms part of the aircraft cabin floor. The base support structure 104 includes support elements 106, 108, 110. In the illustrated implementation, support elements 106 and 108 are configured as cross tubes, and support element 110 is configured as a vertical support leg. However, it should be understood that support elements 106, 108, and 110 can be support elements of any type and construction (e.g., different types of seat support members). It can be seen that, in the illustrated example, each of the passenger seats 102a, 102b, and 102c is connected to and supported on support elements 106 and 108. Furthermore, the base support structure 104 is a frame structure that connects the passenger seats 102a, 102b, and 102c to the vehicle floor.

[0024] In the illustrated example, the central passenger seat 102b is configured as a convertible seat assembly 120. That is, the central passenger seat 102b is convertible for different applications or uses, such as for non-seat purposes (e.g., loading purposes and / or privacy purposes). In some instances, the central passenger seat 102b is configured to be easily retrofitted to remove seat features and replace them with different components defining different features or uses. It should be noted that any passenger seat 102, including the end passenger seats 102a and passenger seats 102c, may optionally be configured as a convertible seat assembly 120. Therefore, although the examples described herein relate to the central passenger seat 102b, convertibility is not limited to only one seat 102, a group of seats 102, or a type of seat 102.

[0025] The seat assembly 120 of the central passenger seat 102b includes, in some configurations, a base structure 130 having a seat panel housing 132 and a backrest housing 134. It should be understood that the base structure 130 is, in various instances, a frame structure on which the seat upholstery is arranged. The seat panel housing 132 and the backrest housing 134 are also, in various instances, frame structures, each configured to support the seat upholstery. That is, the base structure 130, the seat panel housing 132, and the backrest housing 134 are all configured to have complementary structures to connect and support the seat components to define the seat assembly. As described in more detail, the base structure 130, the seat panel housing 132, and the backrest housing 134 are also configured to allow for the connection and support of components to define different features relative to the seat assembly.

[0026] In the illustrated example, the seat assembly 120 of the central passenger seat 102b includes a seat surface device 140 detachably attached to the base structure 130. That is, the seat surface device 140 is removably mounted to the base structure 130 to define a seat device usable for the passenger seat (see [example missing]). Figure 1A In some instances, the seat surface device 140 is a substructure of the seat assembly. In the illustrated example, the seat surface device 140 includes a seat cushion 142 and a backrest cushion 144. Optionally, a headrest cushion 146 is included in the illustrated example. Thus, a padded seat area for the passenger is defined.

[0027] In one example, the headrest cushion 146 is part of and detachably attached to the backrest cushion 144. In some examples, the seat cushion 142 and the backrest cushion 144 are separate components. Alternatively, the seat surface device 140 is configured as a single element (e.g., an integral design), wherein the seat cushion 142 and the backrest cushion 144 together form an integral body structure. In the illustrated example, the seat surface device 140 is generally L-shaped to define a seat for a passenger. That is, when the seat surface device 140 is arranged on the base structure 130, the seat assembly 102 forms the passenger seat 102. It should be understood that the seat surface device 140 can have different shapes and configurations, such as based on seat requirements, aircraft design, cabin use, etc.

[0028] Figure 1B A perspective view shows a passenger seating assembly 100 having two passenger seats 102a, 102c (e.g., non-convertible seats or seats currently arranged in a seating configuration) and a seat assembly 120 with a detached central passenger seat 102b. Specifically, the seat surface device 140 is removed from the base structure 130. In this detached state, the base structure without any padding is exposed and includes elements that facilitate convertibility or modification, as described in more detail herein.

[0029] For example, seat surface device 140 and / or utility surface device 170 are configured as modification components. In one instance, the entire seat assembly is a modification component. In some instances, base structure 130 is a modification component that can be assembled to an already used and installed seat frame structure. In some instances, the base structure is attached to a common seat frame structure to provide a modifiable surface. For example, when one or the other of the seat cushion device and utility surface device is removed, the seat cushion device and utility surface device can be interchangeably and alternatively attached to the base structure.

[0030] As can be seen, the base structure 130 includes one or more attachment structures 150 (e.g., coupling or mounting elements) to receive a corresponding structure (not shown) of the seat surface device 140. That is, complementary coupling devices are provided in various instances. As described herein, the seat surface device 140 defines a seat cushion device for a passenger seat. It should be understood that the seat surface device 140 may have or define different seat cushion devices formed by different constructions of the seat pad 142 and / or backrest pad 144, such as having different hardness, seat covers, colors, sizes, etc. In one instance, these seat surface devices 140 are interchangeable and detachably attached (e.g., removably coupled) to the base structure 130 as needed by consumers, airlines, etc. The attachment structures 150 may have different coupling devices as needed or required. For example, the attachment structure 150 may be a clip-on connector, a threaded connector, and / or a simple and secure snap / lock connector and / or other engagements (e.g., hooks and loops) for a releasable connection between the base structure 130 and the seat surface device 140. As should be understood, the means of attachment structure 150 can vary. For example, the positioning, orientation, size, type, etc. of attachment structure 150 on base structure 130 can vary.

[0031] In some instances where the utility surface device 170 provides entertainment equipment and / or an in-flight entertainment interface, the utility surface device 170 includes a detachable power supply connection. In some instances, the power supply connection is disposed on the base structure 130 and coupled to an onboard power source.

[0032] In some instances, the seat surface device 140 is configured as a seat assembly substructure, wherein one or more attachment structures of attachment structure 150 (or other elements) are configured as integrated quick-attachment points. In some instances, the utility surface device 170 is also configured as a seat assembly substructure with integrated quick-attachment points. The use of substructures allows for personalization.

[0033] In some instances, crew members can easily remove one of the surface devices (e.g., seat surface device 140 or utility surface device 170) and interchange the surface device with another surface device. For example, attachment structure 150 includes a locking device that can only be unlocked by a crew member using a specific tool, thereby preventing passengers from removing or altering the surface device.

[0034] Figure 1C A perspective view shows a passenger seating arrangement 100 having two passenger seats 102a, 102c (e.g., non-convertible seats or seats currently arranged in a seating configuration) and a seat assembly 120 configured as a functional element 160. That is, the seat assembly 120 has been separated from the passenger seat 102b (e.g., ... Figure 1A(As shown) is converted into utility element 160. It should be understood that a reverse conversion from utility element 160 to passenger seat 102b is contemplated. That is, conversion between different configurations of passenger seat assembly 100 is possible.

[0035] The seat assembly 120 in this example includes a utility surface device 170, wherein the base structure 130 can be converted into a passenger seat 102c and / or a utility element 160, depending on whether the seat surface device 140 or the utility surface device 170 is detachably attached to the base structure 130. When the utility surface device 170 is arranged on the base structure 130, the seat assembly 120 forms the utility element 160.

[0036] In the illustrated example where utility element 160 defines the central utility element (by modifying the middle seat 102b), utility element 160 is usable by passengers seated in passenger seat 102a and / or passenger seat 102c. That is, utility element 160 is usable by passengers on either side of the middle seat 102b. Utility element 160 in such an arrangement is thus configured as a console element of a known business and / or first-class seat to provide a number of comfort and utility features. For example, utility element 160 is divided into multiple utility areas 162, which may be axisymmetric (or have other symmetries) (two are shown in this example, but more or fewer utility areas may be provided), such that the same features are provided to both the left and right passengers adjacent to utility element 160. That is, utility areas 162 may be constructed similarly or differently. For example, each utility area 162 may include the same utility features. In other instances, such as when the passenger seating assembly 100 is configured as a dual-seat assembly or when it is desired or necessary for a passenger on only one side of the utility element 160 to approach, the utility element 160 is configured for use by a single passenger. In some instances, the utility areas 162 are arranged on opposite or lateral sides of the base structure 130. For example, in some instances, the utility surface assembly includes two utility areas 162 located on each lateral side of the base structure 130. For example, the upper surface element 182 and / or the bottom surface element 180 include left and right utility areas for a left and right passenger adjacent to the seat assembly.

[0037] In the illustrated example, the utility surface device 170 (and therefore utility element 160) includes storage compartments 172 and / or carrying cases, shelves 174, cup holders 176, partition walls 178 (e.g., privacy walls), entertainment equipment, in-flight entertainment interfaces (IFEs), table facilities, and / or passenger support elements (e.g., armrests, booster seats, headrests, such as side headrests for laterally seated passengers) and / or various available features for passengers. It should be understood that different features or elements may be provided. For example, in one or more examples, the utility surface device 170 includes at least one of the following: storage compartments, shelves, cup holders, partition walls, entertainment equipment, in-flight entertainment interfaces such as auxiliary A / C output ports, ports, plugs, and sockets, and / or passenger support elements. Passenger support elements are, for example, armrests, booster seats, or headrests, such as side headrests for laterally seated passengers.

[0038] Furthermore, in some instances, the seating assembly can be converted from a passenger seat into a utility component for crew members. In these instances, the utility component for crew members provides storage compartments and shelves, including storage features and / or locker features for multiple different items, while being easily accessible to crew members within the passenger seating compartment.

[0039] In one example, the utility surface device 170 includes a bottom surface element 180 and an upper surface element 182, wherein the upper surface element 182 extends generally vertically from the bottom surface element 180. The bottom surface element 180 and the upper surface element 182 may be made of different materials, such as synthetic materials. In some examples, the bottom surface element 180 and the upper surface element 182 are configured as a rigid shell. In some examples, the bottom surface element 180 and the upper surface element 182 include a sleeve made of a soft material (such as fabric and / or leather) to provide an aesthetic appearance or comfort (e.g., to cover the rigid shell).

[0040] In some instances, the utility surface device 170 is constructed as a single element. For example, the utility surface device 170 is generally L-shaped. The utility surface device 170 forms an integral main structure with various utility features. Furthermore, multiple utility surface devices 170 can be provided, each with different utility features, colors, privacy features, and sizes, so that the utility surface devices 170 are interchangeable on the base structure 130. That is, in some instances, different pre-constructed utility surface devices 170 are provided to facilitate the conversion of one or more seats 102. In some instances, the utility surface device 170 includes one or more modifiable elements. The utility surface devices 170 are interchangeable and detachably attached to the base structure 130 according to the needs of customers, airlines, etc. For example, in some instances (e.g., if two passengers in passenger seats 102a, 102c know each other), a partition wall 178 is not provided or installed.

[0041] In some instances, the utility surface device 170 includes a corresponding attachment structure (not shown) configured for attachment to the attachment structure 150 of the seat panel housing 132. Specifically, in various instances, the bottom surface element 180 includes a corresponding attachment structure configured for attachment to the attachment structure 150 of the seat panel housing 132 (similar to the attachment of the seat surface device 140 described herein).

[0042] In some instances, the utility surface device 170 includes a corresponding attachment structure (not shown) configured for coupling to the attachment structure 150 of the backrest housing 134. Specifically, the upper surface element 182 includes a corresponding attachment structure configured for coupling to the attachment structure 150 of the backrest housing 134. The attachment structure 150 may be, for example, a clip-on connector, a threaded connector, and / or a simple and secure snap-on / lock-on connector and / or other engagement elements (e.g., hooks and loops) for a releasable connection between the base structure 130 and the utility surface device 170. It should be noted that the connection means for different devices (such as the seat surface device 140 and the utility surface device 170) may be the same or different. That is, when constructing the seat 102 in the seat surface device 140 and the utility surface device 170, one or more of the same attachment structures 150 may be used, or when constructing the seat 102 in the seat surface device 140 and the utility surface device 170, one or more of different attachment structures 150 may be used. For example, some attachment structures 150 used in constructing seat 102 in seat surface device 140 are not used in constructing seat in practical surface device 170, and vice versa.

[0043] Figure 2 The passenger seating unit 102 is shown in top view. The passenger seating unit has two passenger seats 102a and 102c and a functional element 160 (similar to...). Figure 1CThe middle seat 102b of the seat assembly 120. In this example, the utility area 162 is similarly constructed to have the same features.

[0044] Figure 3 A passenger seating assembly 100 is shown in a side view. This assembly includes a passenger seat 102a and a seat assembly 120 comprising a seat 102b configured as a utility element 160. As can be seen more clearly in this figure, a partition wall 178 is configured to provide privacy to the passenger located in each of the seats 102a, 102b. In some instances, the partition wall 178 is removable (e.g., if privacy is not desired).

[0045] Therefore, multiple implementations, as described in one or more examples, provide seats that include seat components that allow for easy conversion to different uses. As described herein, a “typical” seat configuration can be converted into a practical configuration to allow for the acquisition of features that may not be available to some passengers. In some instances, interchangeable seat surface arrangements have different features, such as different decorative characteristics and / or seat cover characteristics and / or colors and / or comfort features. Furthermore, interchangeable practical surface arrangements are provided with different practical features, for example, for different needs and requirements of individual passengers.

[0046] Some examples described in this article are used for, for example, regarding Figures 3 to 6 The manufacturing and repair applications shown and described herein. Therefore, the examples described herein are in… Figure 4 The equipment and maintenance method 200 shown in the figure Figure 5 Described in the context of the device 300 shown. Figure 4 The diagram illustrates a method 200 for manufacturing and maintaining equipment, based on an example. In one example, during pre-production, the method 200 includes the specification and design of equipment 300 (step 202) and material procurement (step 204). During production, the manufacturing of components and sub-assemblies of equipment 300 is performed (step 206), and system integration is carried out (step 208). Subsequently, equipment 300 undergoes certification and delivery (step 210) for use (step 212). When used by the customer, routine maintenance and repairs of equipment 300 are scheduled (step 214), which in one example includes modification, remodeling, refurbishment, and other maintenance or repairs subject to construction management, as described herein.

[0047] In one instance, each process in the equipment manufacturing and maintenance method 200 is performed or implemented by a system integrator, a third party, and / or an operator. In these instances, the operator is the customer. For the purposes of this specification, a system integrator includes any number of equipment manufacturers and main system subcontractors; a third party includes any number of vendors, subcontractors, and suppliers; and in one instance, the operator is the owner of the equipment or group of equipment, the administrator responsible for the equipment or group of equipment, the user operating the equipment, a leasing company, a military entity, a service organization, etc.

[0048] Now for reference Figure 5 300 pieces of equipment were provided. For example... Figure 5 As shown, an example of device 300 is flight device 302, such as aerospace vehicles, aircraft, air cargo, flying cars, satellites, planetary probes, deep space probes, solar probes, etc. Also, Figure 5 As shown, other examples of equipment 300 are ground transportation equipment 304, such as automobiles, trucks, heavy equipment, construction equipment, small boats, ships, submarines, etc. Figure 5 Other examples of the device 300 shown are modular devices 306, which include at least one or more of the following modules: an air module, a payload module, and a ground module. The air module provides airlift or flight capability. The payload module provides the ability to transport objects such as cargo or living objects (people, animals, etc.). The ground module provides ground mobility capability. The solutions and examples in this document can be applied individually or in groups to each module, such as an air module and a payload module, or a payload module and a ground module, or all modules.

[0049] Now for reference Figure 6 A more detailed illustration of flight device 302 is shown, in which the implementation described herein is advantageously employed. In this example, flight device 302 is achieved through... Figure 4 The equipment manufacturing and maintenance method 200 produces an aircraft and includes a fuselage 402 having an interior 406 and multiple systems 404, the interior of which may include convertible seats (e.g., seat 102) as described herein. Examples of the multiple systems 404 include one or more of a propulsion system 408, an electrical system 410, a hydraulic system 412, and an environmental system 414. However, other systems may also be included. Although aerospace examples are shown, different advantageous examples are applied to other industries, such as the automotive industry, etc.

[0050] As used herein, structures, constraints, or elements "constructed" to perform a task or operation are specifically structurally formed, constructed, or adapted in a manner corresponding to the task or operation. For clarity and to avoid ambiguity, objects that can only be modified to perform a task or operation are not "constructed" to perform the task or operation as used herein.

[0051] As will be apparent to those skilled in the art, any range or value given herein may be extended or changed without losing the desired effect.

[0052] Although the subject matter has been described in language relating to structural features and / or methodological actions, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or actions described above. Rather, the specific features and actions described above are disclosed as examples of implementing the claims.

[0053] It should be understood that the benefits and advantages described above may apply to one instance or to several instances. These instances are not limited to those that solve any or all of the stated problems or have any or all of the stated benefits and advantages. It should also be understood that reference to "one" means one or more of those items.

[0054] The term "comprising" is used in this specification to mean including one or more features or actions that follow it, without excluding the presence of one or more additional features or actions. The terms "comprising," "including," and "having" are intended to be inclusive and mean that additional elements may exist besides those listed. In other words, the use of "comprising," "including," "having," "containing," "involving," and variations thereof is intended to cover both the items listed thereafter and any additional items. Furthermore, the reference to "an implementation" is not intended to be construed as excluding the existence of additional implementations that also incorporate the described features. The term "instantaneous" is intended to mean "an instance of...".

[0055] When describing elements of multiple aspects and implementations or instances thereof, the articles “a,” “an,” “the,” and “described” are intended to mean the presence of one or more elements. In other words, unless explicitly stated otherwise, the indefinite articles “a,” “an,” “the,” and “described” as used in the specification and claims should be understood to mean “at least one.”

[0056] The phrase “one or more of the following: A, B, and C” means “at least one A and / or at least one B and / or at least one C.” As used in the specification and claims, the phrase “and / or” should be understood to mean “any one or both” of the elements so combined, i.e., elements that are combined in some cases and separate in others. Multiple elements listed with “and / or” should be interpreted in the same way, i.e., “one or more” elements so combined. Other elements may optionally be present, whether related to or unrelated to those specifically identified by the “and / or” clause. Thus, in one implementation, as a non-limiting example, when used in conjunction with open-ended language such as “comprising,” a reference to “A and / or B” may refer only to A (optionally including elements other than B); in another implementation, only to B (optionally including elements other than A); in yet another implementation, to both A and B (optionally including other elements); and so on.

[0057] As used in the specification and claims, “or” should be understood to have the same meaning as “and / or” as defined above. For example, when items in a separate list are separated, “or” or “and / or” should be interpreted as inclusive, i.e., including multiple elements or at least one of the elements in the list, but also including more than one, and optionally additional unlisted items. Only explicitly indicating the opposite terms, such as “only one” or “exactly one”, or when used in claims, “consisting of” will refer to including many elements or exactly one element in the list. In general, when used before an exclusive term, the term “or” should be interpreted only as indicating an exclusive alternative (i.e., “one or the other but not both”), such as “any one,” “one of them,” “only one,” or “exactly one.” “Substantially consisting of”, when used in claims, has its ordinary meaning as used in the field of patent law.

[0058] As used in the specification and claims, the phrase "at least one" in relation to a list of one or more elements should be understood to mean at least one element selected from any one or more elements in the list of elements, but not necessarily including at least one of each element specifically listed in the list of elements, and does not exclude any combination of elements in the list of elements. This limitation also allows for the optional presence of elements other than those specifically identified in the list of elements referred to by the phrase "at least one," whether related to or unrelated to those specifically identified elements. Therefore, in one implementation, as a non-limiting example, "at least one of A and B" (or equivalently "at least one of A or B", or equivalently "at least one of A and / or B") may refer to at least one (optionally including more than one) A, while B is absent (and optionally includes elements other than B); in another implementation, it refers to at least one (optionally including more than one) B, while A is absent (and optionally includes elements other than A); in yet another implementation, it refers to at least one (optionally including more than one) A and at least one (optionally including more than one) B (and optionally includes other elements); and so on.

[0059] The use of ordinal terms such as "first," "second," and "third" in the claims to modify the claim elements themselves does not imply any priority, precedence, or order of one claim element relative to another claim element, or the chronological order of actions of the method. Ordinal terms are used only as labels to distinguish one claim element with a certain name from another element with the same name (but for the purpose of using ordinal terms, to differentiate claim elements).

[0060] Having described in detail various aspects of numerous examples, it will be apparent that modifications and variations are possible without departing from the scope of the various aspects defined in the appended claims. Because various changes can be made to the above constructions, products, and methods without departing from the scope of the various aspects described herein, everything intended to be included in the above description and shown in the accompanying drawings should be interpreted illustratively and not in a restrictive sense.
