The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
[0001] Present disclosure, in general, relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to a mounting assembly for a vehicle. Further, embodiments of the present disclosure relate to an assembly for mounting a vehicle component, a system for operating the mounting assembly and a method thereof.
BACKGROUND OF THE DISCLOSURE
[0002] Generally, vehicles include a number of frictionally engaged components (also referred to as driving components) such as motors, pumps, engine, gears of gearbox, cultch, and the like, which may generate noise and vibrations during operation or during engagement with other components. Other conditions such as worn-out components, misalignment, insufficient/inadequate lubrication, and the like, may also cause noise and vibration in the vehicle. An end user experience of a vehicle may be assessed by noise, vibration and harshness (designated as “NVH”) test, which involves subjecting a component or a subassembly of the vehicle to vibrations at different frequencies, as a means for determining mode shapes and isolating buzzes, squeaks, and rattles.
[0003] Even though the components are rigidly fixed in the vehicle, the vibrations may require to be suppressed using dampener mountings. Conventionally, such mountings are designed to absorb vibrations generated in vehicle components. For example, an engine mount is disposed between a vehicle body and an engine to support the engine, where the engine mount may include a rubber padding, which serves to absorb and reduce noise and vibrations from being transmitted to a cabin of the vehicle via the vehicle body. The mountings are defined with a core that is connectable to the vehicle component. Further, the mountings are incorporated with stoppers, to limit the movement of the core of the mountings in x, y and z directions. In some set-ups, the stoppers are positioned proximal to the core of the mountings with a gap between the stoppers and the core. However, if this gap is large, the core may displace excessively which may cause damage to the rubber padding. On the other hand, if the gap is small, the stoppers and the core may engage with each other frequently, which may also cause damage. Accordingly, maintaining an optimal gap between the stopper and the core is necessary.

[0004] While the gap may be set at an optimal value at the time of manufacturing of the vehicle, over the course of usage of the vehicle, the rubber padding may be subject to creep. The creep may cause the gap to deviate from the optimal value.
[0005] The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional mechanisms.

DETAILED DESCRIPTION
[0030] While the embodiments in the disclosure are subject to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the figures and will be described below. It should be understood, however that it is not intended to limit the

disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.
[0031] The terms “comprises”, “comprising”, or any other variations thereof used in the disclosure, are intended to cover a non-exclusive inclusion, such that a device, assembly, mechanism, system, method that comprises a list of components does not include only those components but may include other components not expressly listed or inherent to such system, or assembly, or device. In other words, one or more elements in a system proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or method.
[0032] Disclosure is described in the following paragraphs with reference to Figures 1a to 4b. In the figures, the same element or elements which have same functions are indicated by the same reference signs. It is to be noted that, the vehicle is not illustrated in the figures for the purpose of simplicity. One skilled in the art would appreciate that the assembly, the system and the method as disclosed in the present disclosure may be used in any vehicle including but not liming to heavy and light commercial vehicles, load carrying vehicles, and the like.
[0033] Figure 1a is an exemplary embodiment of an assembly (100) for mounting a vehicle component (16) on a vehicle [not shown in figures]. The assembly (100) comprises a mounting unit (5), a first piston (3) and a first stopper (4). The mounting unit (5) is connectable to a frame
(15) of the vehicle and connectable to at least a portion of the vehicle component (16) [as seen in Figure 2]. The mounting unit (5) may be connected to the frame (15) of the vehicle through a plurality of fasteners on at least one of a top end and a bottom end of the mounting unit (5). The vehicle component (16) may be, for example, an engine, a transmission, a gearbox, a pump, a motor, and the like. Further, the frame (15) may be including, but not limited to, chassis, sub-frame, cross-members, and the like, on which the mounting unit (5) may be mounted and rigidly fixed. Here, for description of the assembly (100) of the present disclosure, the vehicle component
(16) is depicted to be an engine of the vehicle, while other vehicle components such as mentioned above can also be considered without deviating therefrom.

[0034] In the illustrative embodiment, the mounting unit (5) comprises a core (7) and a housing (8). The core (7) is coupled to the vehicle component (16), where at least a portion of such vehicle component (16) may be coupled to and connected with the core (7) of the mounting unit (5) as seen in Figures 1a and 1b. For example, the core defines an opening (7’), in which an arm of the vehicle component (16) is mounted. The core (7) is connected to the housing (8) by a dampening material (17) configured to absorb the vibrations from the core (7) transmitted by the vehicle component (16). The core (7) is encompassed by the dampening material (17) on at least one side, such that the core (7) is positioned at the center of the mounting unit (5) and the dampening material (17) may be adhesively connected between the core (7) and the housing (8) of the mounting unit (5). Further, the dampening material (17) may be connected to the core (7) and the housing (8) by vulcanization processes. The dampening material (17) absorbs vibrations from movement of the core (7) when the vibrations from the vehicle component (16) are transferred to the core (7). The dampening material (17) prevents/reduces vibrations of the vehicle component (16) from being transferred to the housing (8). The housing (8) is configured to encompass the core (7) and define a first passage (6), where at least a portion of the first piston (3) in the first passage (6) is displaceable relative to the core (7).
[0035] The first piston (3) is movably disposed in the first passage (6) and is adapted to displace in the first passage (6) on supply of the fluid to the first passage (6). The first piston (3) comprises a first piston head (3a), and a first piston rod (3b). The first piston head (3a) is disposed in the first passage (6) and the first piston rod (3b) is connected to the first piston head (3a) and extends between the first piston head (3a) and a first stopper (4). In an embodiment, the first stopper (4) may be configured to limit movement of the core (7) and the arm of the vehicle component (16) in one direction, such as in the vertically upward direction, which may occur due to vibrations of the vehicle component (16), which in turn, may occur during the movement of the vehicle. The first stopper (4) prevents excessive displacement of the core (7). Moreover, the first stopper (4) prevents the dampening material (17) from cracking or popping out from the assembly (100) due to excessive displacement of core (7). In an embodiment, the first stopper (4) may be positioned above the core (7) of the mounting unit (5) to restrict upward movement of the core (7) and the arm of the vehicle component (16) in the upward direction.

[0036] In an embodiment, the first piston head (3a) may be fitted in the first passage (6) with clearance required for movement of the first piston (3). The first piston head (3a) may divide the first passage (6) into two portions i.e., an upper portion and a lower portion and is designed to be filled with the fluid. The first stopper (4) is fixedly coupled to the first piston (4), and is positioned displaceably from the core (7) of the mounting unit (5), where the distance between the first stopper (4) and the core (7) of the mounting unit (5) is defined as a stopper gap as best seen in Figure 1a. The first piston (3) is displaced by supplying the fluid to the first passage (6) to vary the stopper gap between the first stopper (4) and the core (7) of the mounting unit (5).
[0037] Again referring to Figure 1a and Figure 1b, the first passage (6) is defined with at least two ports comprising a first port (2a) and a second port (2b) for in-flow and out-flow of the fluid in the first passage (6). Further, the first port (2a) is positioned in the upper portion of the first passage (6) and the second port (2b) is positioned in the lower portion of the first passage (6). In an embodiment, each of the ports (2a, 2b) are connected to a fluid reservoir (not shown in Figures) through plurality of tubes (1) configured to allow flow of the fluid between the first passage (6) and the fluid reservoir. Each port may be connected to at least one tube of the plurality of tubes (1) to allow flow of the fluid. In the illustrative embodiment, the first port (2a) is configured to allow in-flow of the fluid into the first passage (6) when the second port (2b) allows out-flow of the fluid from the first passage (6) to displace the first piston (3) vertically downwards. The second port (2b) is configured to allow in-flow of the fluid into the first passage (6) when the first port (2a) allows out-flow of the fluid from the first passage (6) to displace the first piston (3) vertically upwards.
[0038] In an embodiment, the fluid may flow into the lower portion through the second port (2b) displacing the piston linearly and vertically upwards, where the fluid in the upper portion may be displaced by the first piston head (3a) and flows out from the upper portion. The vertically upward movement of the first piston (3) may displace the first stopper (4) away from the core (7) of the mounting unit (5), thereby increasing the stopper gap [hereinafter interchangeably referred to as “gap” or “first stopper gap”] between the first stopper (4) and the core (7) as shown in Figure 1a. Similarly, the fluid flows into the first passage (6) through the first port (2a) and is configured to displace the first piston (3) vertically downward, thereby moving the first stopper (4) closer to the core (7). While the fluid flows inward from the first port (2a) into the upper portion of the first

passage (6), the piston is displaced downward and the fluid in the lower portion of the first passage (6) flows outward from the lower portion due to displacement of the first piston (3). This fluid flow reduces the first stopper gap between the first stopper (4) and the core (7) of the mounting unit (5) as shown in Figure 1b. In the illustrative embodiment, the first passage (6) is aligned along the vertical axis (ZZ’) of the assembly (100) to allow vertical displacement of the first piston (3) relative to the vehicle component (16) and core (7) of the mounting unit (5). The first stopper (4) is fixedly coupled to the first piston (3) at a bottom end and may be configured to face the vehicle component (16) and restrict movement of the vehicle component (16). In the illustrative embodiment, the first stopper (4) is configured to face the core (7) of the mounting component. The fluid flow to and from the first passage (6) allows adjustment of the first stopper gap to restrict the movement of the core (7) of the mounting unit (5).
[0039] In an embodiment, the assembly (100) is depicted with a first passage (6) and a second passage (6’) that are defined vertically opposite to each other within the housing (8). Further, one end of each of the first passage (6) and the second passage (6’) are facing the core (7) whereas the other end of each of the first passage (6) and the second passage (6’) are proximal to a top end and a bottom end of the housing (8). Further, the first passage (6) and the second passage (6’) may be aligned along the vertical axis (ZZ’). The first passage (6) is defined with the first piston (3) and the second passage (6’) is defined with the second piston (3’). The first piston (3) and the second piston (3’) are displaceably positioned in the first passage (6) and the second passage (6’) respectively. Here, the number of passages and pistons should not be considered to be a limitation.
[0040] The second piston (3’) is fixedly coupled with a second stopper (4’) facing the vehicle component (16) to restrict the movement of the vehicle component (16). The second piston (3’) comprises a second piston head (3a’) and a second piston rod (3b’) connected to and extending between the second piston head (3a’) and the second stopper (4’). At least a portion of the second piston (3’) in the second passage (6’) is displaceable relative to the vehicle component (16) based on fluid flow in the second passage (6’). The second passage (6’) and the first passage (6) are defined on opposite sides in the mounting unit (5), where the core (7) is positioned between the first piston (3) and the second piston (3’). The second passage (6’) may be configured to receive the fluid for adjusting the distance between the second stopper (4’) and the vehicle component (16). In an embodiment, the gap [hereinafter referred to as “second stopper gap”] between the

second stopper (4’) and the core (7) is varied based on the flow of the fluid in the second passage (6’). In an embodiment, the second stopper (4’) may be configured to restrict the movement of the core (7) and the vehicle component (16) in a direction opposite to that of the first stopper (4), such as the vertically downward direction.
[0041] The second piston head (3a’) of the second piston (3’) may divide the second passage (6’) into two portions i.e., an upper portion and a lower portion to be filled with the fluid. In an embodiment, the second passage (6’) may be configured with at least two ports comprising a third port (2a’) and a fourth port (2b’) for in-flow and out-flow of the fluid in the second passage (6’). In the illustrative embodiment, the third port (2a’) is positioned in the lower portion of the second passage (6’) and the fourth port (2b’) is positioned in the upper portion of the second passage (6’). In an embodiment, when the fluid flows into the lower portion through the third port (2a’), the piston may be displaced vertically in an upward direction, where the fluid in the upper portion may be displaced by the second piston head (3a’) and flows out from the upper portion. The vertically upward movement of the second piston (3’) may displace the second stopper (4’) towards the core (7) of the mounting unit (5) and the vehicle component (16), thereby decreasing the gap [hereinafter interchangeably referred to as “stopper gap” or “second stopper gap”] between the second stopper (4’) and the core (7) as shown in Figure 1b. Similarly, the fluid flows into the upper portion of the second passage through the fourth port (2b’) and displaces the second piston (3’) vertically downward, thereby displacing the second stopper (4’) away from the core (7) of the mounting unit (5) and the vehicle component (16). While the fluid flows inward from the fourth port (2b’) into the upper portion of the second passage (6’), the second piston (3’) is displaced downward and the fluid in the lower portion of the second passage (6’) flows outward from the lower portion due to displacement of the second piston (3’). This fluid flow increases the second stopper gap. In the illustrative embodiment, the second passage (6’) is aligned along the vertical axis (ZZ’) of the assembly (100) to allow vertical displacement of the second piston (3’) relative to the vehicle component (16) and core (7) of the mounting unit (5). The second stopper (4’) is fixedly coupled to the second piston (3’) on an upper end and may be configured to face the vehicle component (16) and restrict movement of the vehicle component (16).
[0042] In the above-explained manner, the first stopper (4) is configured to adjust distance between the first stopper (4) and the vehicle component (16) in response to displacement of the

first piston (3) in the first passage (6) and the second stopper (4’) is configured to adjust distance between the second stopper (4’) and the vehicle component (16) in response to displacement of the second piston (3’) in the second passage (6’). In an embodiment, the assembly (100) comprises one or more sensors (9) configured to sense a distance between the first stopper (4) and the vehicle component (16) and the second stopper (4’) and the vehicle component. In an embodiment, the one or more sensors (9) may be positioned on at least one of the core (7), the first stopper (4) and the second stopper (4’). In an embodiment, the one or more sensors (9) may be, for example, capacitive proximity sensors, ultrasonic proximity sensors, or hall effect sensors. In an illustrative embodiment, the one or more sensors includes at least two capacitive proximity sensors where the one capacitive proximity sensor is positioned on one side of the core (7) facing the first stopper (4) and an other capacitive proximity sensor is positioned on the other side of the core (7) facing the second stopper (4’).
[0043] In an embodiment, the first piston (3) and the second piston (3’) may be configured with an O-ring (10) configured to restrict fluid flow within the first passage (6) and the second passage (6’). The fluid flow to and from the second passage (6’) allows adjustment of the second stopper gap and to restrict the movement of the core (7) of the mounting unit (5).
[0044] Referring now to Figure 3 which is an exemplary embodiment of the present disclosure illustrating a block diagram of a system (300) for controlling an assembly (100) for mounting the vehicle component (16) on the vehicle. In an illustrative embodiment, the system (300) comprises an engine control unit (12), a vehicle body control unit (13) communicatively coupled to the control unit (14) and a pump (11) coupled to the control unit (14) and fluidly connected to the first passage (6).
[0045] In an embodiment, the one or more sensors (9) are configured to sense distance between the first stopper (4) and the vehicle component (16). In an embodiment, the one or more sensors (9) may be positioned on the core (7) or on the first stopper (4). The control unit (14) is communicatively coupled to the one or more sensors (9) where the control unit (14) may be configured to receive a signal corresponding to the distance between the first piston (3) and the vehicle component (16). Although not illustrated, in an embodiment, the one or more sensors (9) may transmit the signal to the engine control unit (12), and the control unit (14) may receive the

signal from the engine control unit (12). In an embodiment, the control unit (14) may be communicatively coupled to at least one sensor for detection of key ON state of the vehicle, before ignition of the engine to sense the distance between the first stopper (4) and the vehicle component (16). The control unit (14) determines a first stopper gap defined between the first stopper (4) and the vehicle component (16) based on the signal. The control unit (14) may receive a key ON detection signal from at least one of the vehicle body control unit (13) and the engine control unit (12). The control unit (14) compares the determined first stopper gap with at least one predetermined value. The control unit (14) may determine whether the determined first stopper gap is less than or greater than or equal to the at least one predetermined value. In an embodiment, the at least one predetermined value may include a predefined stopper gap that is optimal, which would permit reasonable movement of the engine and prevent excessive movement of the engine . Then, the control unit (14) transmits an actuation signal to control the fluid supply to the first passage (6) to adjust relative position of the first stopper (4) from the vehicle component (16) by displacing the first piston (3). In an embodiment, the actuation signal from the control unit (14) is transmitted to a pump (11), that is fluidly connected between a fluid reservoir and the first passage (6) to supply fluid through the at least two ports to control displacement of the first piston (3) and the first stopper (4). The pump (11) may be configured to pump (11) the fluid from the fluid reservoir to the first passage (6) and may be configured to pump (11) the fluid from the first passage (6) to the fluid reservoir. For example, the control unit (14) may transmit a first actuation signal if the determined first stopper gap is less than the at least one predetermined value to control the supply of fluid such that the first piston (3) moves away from the vehicle component (16) in the core (7), where the gap between the first stopper (4) and the vehicle component (16) is increased. Conversely, the control unit (14) may transmit a second actuation signal if the determined first stopper gap is greater than the at least one predetermined value/gap to control the supply of fluid such that, the first piston (3) moves towards the vehicle component (16) in the core (7), where the gap between the first stopper (4) and the vehicle component (16) is decreased. Further, the control unit (14) may be configured not to transmit any actuation signal if the determined first stopper gap is equal to the at least one predetermined value to retain the relative position of the first stopper (4) from the vehicle component (16) in the core (7).

[0046] In an embodiment, the mounting unit (5) is defined with a second passage (6’) and comprises a second piston (3’) movably disposed in the second passage (6’) fixedly coupled with a second stopper (4’) to restrict movement of the vehicle component (16). The second passage (6’) is defined opposite to the first passage (6) with the core (7) positioned between the first piston (3) and the second piston (3’). The control unit (14) may be configured to regulate flow of the fluid to the second passage (6’) to allow displacement of the second piston (3’).
[0047] In an embodiment, the control unit (14) may be configured to receive a signal indicative of distance between the second stopper (4’) and the vehicle component (16) from the one or more sensors (9). Then, the control unit (14) determines a second stopper gap defined between the second stopper (4’) and the vehicle component (16) based on the signal. The control unit (14), then, compares the determined second stopper gap with at least one predetermined value. Then, the control unit (14) transmits an actuation signal to control fluid supply to the second passage (6’) to adjust the relative position of the second stopper (4’) from the vehicle component (16) by displacing the second piston (3’) based on the comparison. For example, the control unit (14) may transmit a third actuation signal if the determined second stopper gap is less than the at least one predetermined value to control the supply of fluid such that the second piston (3’) moves away from the vehicle component (16) in the core (7), where the gap between the second stopper (4’) and the vehicle component (16) is increased. Similarly, the control unit (14) may transmit a fourth actuation signal if the determined gap is greater than the at least one predetermined value to control the supply of the fluid such that the second piston (3’) moves towards the vehicle component (16) in the core (7), where the gap between the second stopper (4’) and the vehicle component (16) is decreased. Further, the control unit (14) may be configured to not transmit any actuation signal if the determined second stopper gap is equal to at least one predetermined value to retain the relative position of the second stopper (4’) from the vehicle component (16) in the core (7). In an embodiment, the control unit (14) may compare the determined first stopper gap with a first predetermined value and may compare the determined second stopper gap with a second predetermined value, wherein the first predetermined value and the second predetermined value are variable based on the vehicle requirement.

The method (400) may be implemented in mounting components in vehicles, such as engines, gearboxes, transmission, and motors. The method (400) may be implemented in vehicles,

such as commercial and passenger vehicles. The method (400) may describe in the general context of processor executable instructions in the control unit (14). Generally, the executable instructions may include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform particular functions or implement particular abstract data types.
[0053] The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the scope of the subject matter described herein. Furthermore, the methods can be implemented in any suitable hardware, software, firmware, or combination thereof.
[0054] At block 401, the control unit (14), receives a signal corresponding to distance of a first stopper (4) fixedly coupled to a first piston (3) and the vehicle component (16) from one or more sensors (9) communicatively coupled to the control unit (14). at least a portion of the vehicle component (16) is connectable in a mounting unit (5) and the first piston (3) is movably disposed in the first passage (6) defined in the mounting unit (5).
[0055] At block 402, the control unit (14) is configured to determine a first stopper gap defined between the first stopper (4) and the vehicle component (16) based on the signal received from the one or more sensors (9). Later at block 403, the control unit (14) compares the determined first stopper gap with at least one predetermined value. Then at block 404, the control unit (14) transmits an actuation signal to a pump to control fluid supply to the first passage (6) to adjust the relative position of the first stopper (4) by displacing the first piston (3) based on comparison.
[0056] Referring now to Figure 4b which is an exemplary embodiment of the present disclosure illustrating a flow chart of a method (400) for controlling a second piston (3’) of a mounting assembly (100) of a vehicle. At block 405, the control unit (14) is further configured to receive a signal indicative of the distance between a second stopper (4’) fixedly coupled to the second piston (3’) and the vehicle component (16) from the one or more sensors (9) communicatively coupled to the control unit (14). Then at block 406, the control unit (14) determines a second stopper gap defined between the second stopper (4’) and the vehicle component (16) based on the signal. The control unit (14), then at block 407, compares the determined gap with at least one predetermined

value. Then at block 408, the control unit (14) transmits an actuation signal to control fluid supply to the second passage (6’) to adjust the relative position of the second stopper (4’) by displacing the second piston (3’) based on the comparison.
[0057] In another non-limiting embodiment of the present disclosure, a vehicle is disclosed. The vehicle comprises a vehicle component (16) and an assembly (100) for mounting the vehicle component (16) on the vehicle, the assembly (100). The assembly (100) comprises a mounting unit (5), a first piston (3) and a first stopper (4). The mounting unit (5) is connectable to a frame (15) of the vehicle and connectable to the vehicle component (16). The mounting unit (5) is defined with a first passage (6) for supply of a fluid. The first piston (3) is movably disposed in the first passage (6) and is adapted to displace in the first passage (6) on supply of the fluid to the first passage (6). The first stopper (4) is fixedly coupled to the first piston (3) and is configured to face the vehicle component (16) and restrict movement of the vehicle component (16). The first stopper (4) is configured to adjust distance between the first stopper (4) and the vehicle component in response to displacement of the first piston (3) in the first passage (6).
[0058] In an embodiment, as the system (300) adjusts the first stopper gap and the second stopper gap of the assembly (100) and maintains the optimal stopper gap by displacing the first piston (3) and the second piston (3’), damage of the assembly (100) connected to the vehicle component (16) for mounting may be minimized or eliminated.
[0059] In an embodiment, the creep of the dampening material (17) in the assembly (100) may be avoided by varying the first stopper gap and the second stopper gap which may enhance the NVH performance of the vehicle. The present subject matter can be utilized for conventional mounting units, such as the mounting units other than hydraulic mounting units.
[0060] In an embodiment, the fluid may comprise either a liquid or a compressed gas configured to displace the piston.
[0061] In an embodiment, the assembly (100) may further comprise at least one passage aligned along the horizontal axis to adjust the first stopper gap and the second stopper gap in the horizontal direction besides vertical direction.

[0063] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system (300) having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C,

etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system (300) having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
