     DETAILED DESCRIPTION 
     This detailed description is related to a sprayer assembly that can be connected to a variety of different types of pressurized air sources for spraying a fluid. In addition, the sprayer assembly is configured to work with a variety of different types of pre-filled, fluid containers for holding the fluid to be sprayed. For example, the sprayer assembly can include a sprayer-head assembly that removably and sealingly connects to a canister. In at least some examples, the fluid container can be positioned inside the canister and the sprayer-head assembly can be sealingly connected to the canister (e.g., with the fluid container enclosed within). In addition, the sprayer-head assembly can be connected to various types of pressurized air sources (e.g., shop air in an automotive servicing facility or an air compressor), such that when a trigger of the sprayer-head assembly is actuated (e.g., pressed), the sprayer-head assembly can dispense the fluid from the container (e.g., spray the fluid in an aerosolized form). 
     In contrast to the present disclosure, some conventional solutions can include storing fluid in pressurized canisters (e.g., pressurized aerosol cans that do not rely on an external source of pressurized air). However, pressurized canisters can require additional initial processing (e.g., to pressurize and seal the canister) and can be require various storage logistics (e.g., to protect the canisters). In addition, damage to the pressurized canisters can render the produce unusable and/or can cause damage to surrounding people and products. Furthermore, pressurized canisters can be challenging to recycle, based on challenges associated with cleaning out the fluid, the combination of various types of materials, and the like. However, examples associated with the present disclosure allow for fluid containers to be stored in a non-pressurized state and simply placed into the canister associated with the subject sprayer assembly. In addition, after use, the fluid container can be easily rinsed and reused or recycled, while the sprayer assembly can be reused with subsequent fluid containers. 
     In at least some examples, the sprayer assembly can be used in various contexts and industries that are related to dispersing various types of chemicals or solutions, such as paints, cleaning solutions, fertilizer, pesticide, etc. In an automotive servicing context, the tool can be used to apply an aerosolized liquid to various vehicle components (e.g., brakes, engine components, fluid lines, etc.). 
     In some examples, the sprayer assembly includes the sprayer-head assembly and the canister. In addition, a pre-filled, non-pressurized fluid container can be placed into the canister (e.g., through a top opening), and the sprayer-head assembly can then be attached to the top of the canister. The sprayer-head assembly can be affixed to, or removed from, the top of the canister in various manners. For instance, the sprayer-head assembly can threadably attach or screw onto the top of the canister. In one example, internal pegs inside the top of the sprayer-head assembly can mate into an external groove or channel on the outside of the canister to help in locking and sealing the sprayer-head assembly to the canister. In some examples, the channel can have two (or more) resting positions: engaged and neutral. The neutral area can be a safety feature that keeps the canister connected to the top but does not allow it to seal or charge. The engagement area is indicated by an audible “click” so the user knows that tool can now be used properly. The channel design can impede canister removal until pressure has been released. 
     As indicted, with the sprayer-head assembly removed, the fluid container can be placed into the canister. In examples, a bottom of the canister can include a biasing feature that biases the fluid container “upward” or towards the top opening of the canister. As such, when the sprayer-head assembly is attached to the canister, the fluid container can be pressed into a sealing member of the sprayer-head assembly. For example, the biasing feature can include a convex surface that engages a bottom of the fluid container. As such, a rim (or other top edge) of the fluid container can be pressed into the sprayer-head assembly to reduce the likelihood of over-spilling (e.g., when the system is pressurized). 
     In examples, the sprayer-head assembly can include a fitting for attaching to an air source (e.g., a quick release fitting for connecting to an air hose). The fitting can connect, in the sprayer-head assembly, to a fluid channel that carries pressurized air to the canister and/or the fluid container enclosed in the canister. For example, the sprayer-head assembly can include a handle, which can include the fitting, such that the channel travels through the handle to the canister and/or fluid container. Furthermore, in at least some examples, the channel can be associated with a pressure regulator (e.g., internal within the sprayer-head assembly), which can control the allowable pressure level of the contents to ensure that the device operates the same even with a variety of input pressures. In some instances, the regulator can be adjusted prior to assembly to meet the requirements of the type of fluid that a tool will be used for. 
     In at least some examples, the sprayer-head assembly can include a check valve that can maintain the pressure in the system, even after the air source has been disconnected (e.g., if the fitting is disconnected from the air hose). As such, the sprayer assembly can be pressurized, disconnected from the pressurized air source, and then remotely used to disperse the fluid. Furthermore, the sprayer-head assembly can include a pressure relief valve that allows the sprayer assembly to be depressurized (e.g., for storage or after use). 
     In some examples, the sprayer-head assembly is configured to be used with a standard aerosol valve assembly (e.g., 1″ valve assembly). That is, the sprayer-head assembly can include an aerosol valve compartment that is accessible by a removable flange. The removable flange can be removed (e.g., by removing fastener hardware such as a series of bolts) to access the aerosol valve compartment, such as to insert or replace a valve assembly. As such, examples of the present disclosure allow for the sprayer assembly to be easily maintained by simply removing a used aerosol valve assembly (e.g., where the used valve assembly might be worn, clogged, damaged, etc.) and replacing it with a new aerosol valve assembly. Furthermore, the universality of the sprayer assembly with respect to various valve assemblies allows for the valve assembly to be changed based on the fluid to be dispersed. 
     In at least some examples, the sprayer-head assembly can include a trigger lever that engages the actuator cap of the aerosol valve assembly. For example, the trigger lever can include a size that allows for the trigger lever to be easily operated while the operator grips the handle. 
     The sprayer assembly can include various features. For example, the sprayer assembly can be implemented with off-the-shelf, pre-filled, non-pressurized fluid containers. As such, an operator might not need to handle or pour any fluids which reduces potential hazards from contact and spills. The lack of propellants in the packaging can also allow the fluid to sit on shelves longer and transport better. 
     In some examples, the industrial air coupling, integrated check valve, and regulator allows the device to spray product both while connected to a pressurized air hose or disconnected using the built-up internal air pressure. The regulator can be adjusted to vary the output performance of the fluid in relation to the type of actuator used. 
     Various examples are described below with reference to the drawings, and the relationship and functioning of the various elements of the examples can better be understood by reference to the following detailed description. However, examples associated with the present invention are not limited to those illustrated in the drawings or explicitly described below. It also should be understood that the drawings are not necessarily to scale, and in certain instances details may have been omitted that are not necessary for an understanding of examples disclosed herein, such as conventional assembly. 
       FIG.  1    illustrates a sprayer assembly  10  that can be connected to a variety of different types of pressurized air sources and that is configured for spraying a fluid. In addition, the sprayer assembly is configured to work with a variety of different types of pre-filled, fluid containers for holding the fluid to be sprayed. For example, the sprayer assembly can include a sprayer-head assembly  12  that removably and sealingly connects to a canister  14 . At a high level, the sprayer-head assembly  12  includes a lid  13 , a handle  15 , and a stem  17 , which connects the handle  15  to the lid  13 . In at least some examples, the canister  14  at least partially encloses a volume (e.g., the volume  51  in  FIG.  3   ); the fluid container can be positioned inside the canister  14  (e.g., within the volume); and the sprayer-head assembly  12  (e.g., the lid  13  of the sprayer-head assembly  12 ) can be sealingly connected to the canister  14  (e.g., with the fluid container enclosed within). 
     For example, referring to  FIG.  2   , the sprayer-head assembly  12  is decoupled from the canister  14 , and a fluid container  16  is depicted that could be placed inside the canister  14 . The fluid container  16  is an example, and a variety of different fluid containers could be used with the sprayer assembly  10  (e.g., fluid containers of various sizes and shapes). In at least some examples, the sprayer-head assembly  10  includes a coupling or fitting  18  (e.g., push-style, quick connect, air-hose coupling) for connecting to a pressurized air source (e.g., shop air in an automotive servicing facility or an air compressor). In examples, the pressurized air can pressurize the sprayer assembly  10  (e.g., the container  16 , the canister  14 , etc.), such that when a trigger  20  of the sprayer-head assembly  12  is actuated (e.g., pressed), the sprayer-head assembly  12  can dispense the fluid from the container  16  (e.g., spray the fluid in an aerosolized form). 
     The sprayer assembly  10  an include various other elements. For instance, the sprayer-head assembly  12  can be affixed to, or removed from, the canister  14  in various manners. In some examples, the sprayer-head assembly  12  can threadably attach or screw onto the top of the canister  14 . For example, the sprayer-head assembly  12  and the canister  14  can include threads (e.g., external and internal) that mate to connect the parts. In at least one example, the sprayer-head assembly can include the lid  13  associated with a cavity  22  configured to receive at least a portion of an upper rim  24  of the canister  14 , and the cavity  22  can include a peripheral wall  26  enclosing the sides of the cavity  22 . In addition, the peripheral wall  26  can include an internal protuberance  28  (e.g., peg or post) that projects inwardly from the peripheral wall  26  and into the cavity  22 . In at least some examples, the internal protuberance  28  is configured to mate with a corresponding element associated with the canister  14 . For example, the canister  14  can include an external channel  30  (e.g., channel in the outward oriented face of the canister  14 ) that is configured to receive the internal protuberance  28  when the upper rim  24  of the canister  14  is engaged with the cavity  22 . The sprayer assembly  10  can include one or more sets of mating protuberances and channels. For instance, in accordance with one example, the figures depict three sets of protuberances and channels that can mate with one another. The sprayer assembly  10  can, in some examples, include few than, or more than, three sets. In the sprayer assembly  10 , the protuberance  28  can mate with the canister  14 , and in some examples, the protuberance  28  can mate with a groove or channel on a container of fluid (e.g., a coupling mechanism that projects inwardly towards the cavity and is configured to selectively engage the container of fluid, the canister for holding the container of fluid, or any combination thereof.) 
     The channel  30  can include various elements configured to engage with the internal protuberance  28  at different positions as the internal protuberance  28  is traversed along the channel  20  (e.g., as the sprayer-head assembly  12  and the canister  14  are rotated relative to on another with the mount  24  engaged within the cavity  22 ). In addition, to help illustrate there various elements, reference view  2 A is provided showing the internal protuberance  28  at different positions with respect to the channel  30 . For example, the channel  30  can include a mouth  32  or opening configured (e.g., having a width or size) to receive the internal protuberance  28 , and the mouth  32  can transition to one or more ramp interfaces  34  and  36 . That is, as the internal protuberance  28  enters the channel  30  through the mouth  32  and continues along the channel  30  (e.g., when the parts are rotated), the ramp interfaces  34  and  36  can pull the canister  14  further into the cavity  22  of the sprayer-head assembly  12  to a position. In at least some examples, the ramp interfaces  34  and  36  can transition to one or more channel recesses  36  and  38  configured to retain the internal protuberance  28  in association with a position. For example, as the sprayer-head assembly  12  is rotated relative to the canister  14  (e.g., clockwise in  FIG.  2 A ), the first ramp interface  34  can urge or bias the internal protuberance  28  (e.g., similar to a camming relationship) into the first channel recess  38 , and when rotated further, the second ramp interface  36  can urge or bias the internal protuberance into the second channel recess  40 . In at least some examples, the relatively short travel associated with the channel  30  (e.g., as opposed to a channel that has a longer length and extends to a further extent around the canister  14 ) contributes to easier and faster opening and closing of the sprayer assembly  10 . 
     In at least some examples, the first channel recess  38  and the second channel recess  40  can be associated with different relative degrees of connection or seal between the sprayer-head assembly  12  and the canister  14 . For example, when the internal protuberance  28  is retained in the first channel recess  38 , the canister  14  can be coupled to the sprayer-head assembly (e.g., in the sense that the canister  14  could freely hang from the sprayer-head assembly  12 , while remaining connected to the sprayer-head assembly), but the sprayer assembly  10  might not be configured to contain pressurized air if introduced into the system. In some example, the first channel recess  38  can be associated with a neutral or safety feature, which can keep the canister  14  connected to the sprayer-head assembly, but does not allow the sprayer assembly  10  to seal or charge. When the internal protuberance  28  is retained in the second channel recess  40 , the upper rim  24  of the canister  14  can be pulled into a more tightly sealed connection within the cavity  22 . For example, an annular seal  42  within the cavity  22  can seal against the upper rim  24  of the canister  14  and/or the cavity  22  can include a O-ring, gasket, or other component for sealing against the upper rim  24 . In some examples, based at least partially on the shape of the second channel recess  40  (e.g., a small edge  44  that extends into the channel  30 ), the internal protuberance  28  can audibly “click” when rotated into an engaged position within the second channel recess  40 , and the audible click can notify the user when the sprayer assembly  10  is sealed and configured to be charged. In at least some examples, the edge  44  can also impede disengagement between the canister  14  and the sprayer-head assembly  12 , until pressure within the system has been released. 
     As indicted, with the sprayer-head assembly  12  removed, the fluid container  16  can be placed into the canister  14 . In examples, and referring to  FIG.  2    and  FIG.  3   , a bottom  46  of the canister  14  can include a biasing feature  48  that biases the fluid container  16  “upward” or into the sprayer-head assembly  12 . For example, the biasing feature  48  can include a raised surface that projects or curves towards into the cavity of the canister  14 . As such, when the sprayer-head assembly  12  is attached to the canister  14 , the fluid container  16  (e.g., an upper rim  19  of the fluid container  16 ) can be pressed into an annular shoulder  50  (e.g., annular surface, rim, gasket, etc.) of the sprayer-head assembly  12 . In at least some examples, the biasing feature  48  can be elastic (e.g., such as made from a rubber or elastic material), such that the biasing feature  48  can compress to accommodate containers of various heights, while still pressing the container  16  upwards and into the lid  13 . Among other things, the interfacing of the fluid container  16  with the annular shoulder  50  can reduce the likelihood of fluid from the fluid container  16  spilling over into the canister  14  and can reduce movement of the fluid container  16  when contained within the sprayer assembly  10 . In some examples, the upper rim  19  of the fluid container  16  can contact the annular shoulder  50 . In some examples, the upper rim  19  can be adjacent and directly below the annular shoulder  50 , but not directly abutting, such that a small gap is present between the upper rim  19  and the annular shoulder  50 . In at least some examples, the annular shoulder  50  can include a notch  52  that allows fluid communication to between various compartments within the system (e.g., which might otherwise be sealed off if the surface  50  annularly extended entirely around the cavity  22  and in contact with the upper rim of the fluid container  16 ). For example, via the notch  52 , the cavity  22  of the lid  13  can be in fluid communication with the volume  51  of the canister  14 . 
     In examples, the sprayer-head assembly  12  can include a fitting  18  for attaching to an air source (e.g., a quick release fitting for push connecting to an air hose). The fitting  18  or coupling can connect to a fluid channel  54  or fluid conduit that carries pressurized air to various parts of the sprayer assembly  10 . For example, the fitting  18  can be couple to a portion of the handle  15  (e.g., the end of the handle  15 ), and the fluid channel  54  can extend through the handle  56  and towards the cavity  22 . In at least one example, the sprayer-head assembly  12  can include the stem  17  that connects the handle  15  to the lid  13 , and the fluid channel  54  can extend through the stem  17 . In at least some examples, the sprayer-head assembly  12  can include various other components within the fluid channel  54  (e.g., within the path of the pressurized air as it passes from the fitting  18  to the cavity  22 ). For instance, in at least some examples, the channel  54  can be associated with a pressure regulator  58  (e.g., internal within the stem  17  or within another part of the sprayer-head assembly  12 ), which can control the allowable pressure level of the contents to ensure that the device operates the same even with a variety of input pressures. In some instances, the regulator  58  can be adjusted prior to assembly to meet the requirements of the type of fluid that a tool will be used for. In at least some examples, the sprayer-head assembly  12  can include a check valve  60  that can maintain the pressure in the sprayer assembly  10 , even after the air source has been disconnected (e.g., if the fitting is disconnected from the air hose). For example, the check valve  60  can be positioned in the channel  54  and after the pressure regulator  58 . In some examples, the check valve can be positioned in other parts of the assembly and/or before the pressure regulator  58 . As such, the sprayer assembly can be pressurized, disconnected from the pressurized air source, and then remotely used to disperse the fluid. Furthermore, the sprayer-head assembly can include a pressure relief valve that allows the sprayer assembly to be depressurized (e.g., for storage or after use). 
     Referring to  FIG.  3   ,  FIG.  4   , and  FIG.  5   , the sprayer-head assembly  12  can include an aerosol valve assembly  62 , which is actuatable via the trigger  20 . That is, the trigger  20  can be pivotably or hingedly or rotatably connected to the sprayer-head assembly  12  at the connection  64 , such that when the end  66  of the trigger  20  is depressed, the aerosol valve assembly  62  is actuated. In this sense, the trigger  20  operates as a lever where the connection  64  is a fulcrum. In addition, the trigger  20  can be rotated to an up position (e.g.,  FIG.  4   ) to allow access to the aerosol valve assembly  62 . 
     In some examples, the sprayer-head assembly  12  is configured to be used with an aerosol valve assembly  62  (e.g., 1″ valve assembly), which can include a fluid update tube  63 , a nozzle valve  65  (e.g.  FIG.  3   ), and a nozzle head  67  (e.g., aerosol cap that when depressed can disperse fluid). In addition, the valve assembly  62  can include an annular flange  69  that extends around the nozzle valve  65  and/or nozzle head  67 . In examples, the sprayer-head assembly  12  can include an aerosol valve compartment  68  that is accessible by a removing a cover  70  (e.g., by removing the fasteners  72 ), which can include an opening  71  or through hole for receiving the nozzle head  67 . In examples, the cover  70  can be removed (e.g., by removing fastener hardware such as a series of bolts) to access the aerosol valve compartment  68 , such as to insert or replace a valve assembly  62 . In at least some instances, the valve compartment  68  can include an annular shelf  73  that can support the annular flange  69  of the valve assembly  62 . In addition, when the nozzle assembly  62  is installed, an O-ring  74  (e.g.,  FIG.  3   ) or other sealing member can be positioned between the annular flange  69  and the annular shelf  73 , such that a seal is maintained when the cover  70  is tightened into position. That is, when the cover  70  is installed atop the annular flange  69 , the annular flange  69  can be secured in position between the cover  70  and the annular shelf  73 . As such, examples of the present disclosure allow for the sprayer assembly to be easily maintained by simply removing a used aerosol valve assembly (e.g., where the used valve assembly might be worn, clogged, damaged, etc.) and replacing it with a new aerosol valve assembly. Furthermore, the universality of the sprayer assembly with respect to various valve assemblies allows for the valve assembly to be changed based on the fluid to be dispersed. In examples, various standard valve assemblies can be used with the sprayer assembly  10 . 
     The trigger  20  can include various features. For example, as explained, the trigger  20 , when pressed downward can actuate the aerosol valve assembly  62 . That is, the trigger  20  can include a rubber pad  76  (or similar element) that engages nozzle head  67  of the aerosol valve assembly  62 . In some examples, the trigger  20  can include a size (e.g., length) that allows for the trigger  20  to operate as a lever, which can be easily operated while the operator grips the handle  15 . For example, a distance  80  between the connection  64  and the middle of the nozzle head  65  can be shorter than a distance  82  from the center of the nozzle head  65  to a distal end  84  of the trigger  20 . In some examples, the distance  82  can be twice the distance  80 . The trigger  20  can include other elements as well. For example, the trigger  20  can include a can opener  86 , which can allow for easy opening of pre-filled fluid containers, such as the fluid container  16 . 
     In examples, the sprayer assembly  10  can include other elements as well. For example, a pressure relief valve  88  can be arranged in one or more various locations, and in one example, at least a part of the pressure relief valve  88  extends through the flange  70  and is in communication with the cavity  22 . As such, by opening or closing the valve  88  (e.g., by rotating) pressure can be maintained/sealed or released from the cavity  22 . 
     The sprayer assembly  10  can be constructed of various materials, and in some examples, the canister  14  and at least some parts of the sprayer-head assembly  12  are metal (e.g., aluminum). As such, the sprayer assembly  10  can be robust and withstand harsh environments, drops, etc. 
     Examples associated with the present disclosure allow for fluid containers to be stored in a non-pressurized state and simply placed into the canister associated with the subject sprayer assembly. In addition, after use, the fluid container can be easily rinsed and reused or recycled, while the sprayer assembly can be reused with subsequent fluid containers. In at least some examples, the sprayer assembly can be used in various contexts and industries that are related to dispersing various types of chemicals or solutions, such as paints, cleaning solutions, fertilizer, pesticide, etc. In an automotive servicing context, the tool can be used to apply an aerosolized liquid to various vehicle components (e.g., brakes, engine components, fluid lines, etc.). 
     In some examples, referring to  FIGS.  6  to  9   , a sprayer assembly  610  can include alternative features, which could be used with other types of fluid containers. For example, the sprayer assembly  610  can include a sprayer-head assembly  612  that connects directly to a container  616 . As such, the sprayer assembly  610  can provide a repeat-use sprayer that can be used with pre-filled fluid containers that do not need to be pressurized. In examples, the sprayer assembly  610  may not need a separate canister (e.g., such as the canister  14 ), and the sprayer-head assembly can connect directly to the fluid container  616 . 
     The sprayer-head assembly can include a lid  613  with an internal cavity  622  for receiving the fluid container  616 . In examples, the lid  613  can include a side wall  624  that defines a width of an insertion opening  621  through which the container  616  can pass when being inserted into the cavity  622 . In examples, a size of the opening  621  can be adjusted between a larger size and a smaller size. For example, the opening  621  can be adjusted to a larger size when the container  616  is inserted, and the opening can be adjusted to a smaller size when the container  616  is positioned within the cavity  622 , to allow the side wall  624  (or parts associated with the side wall  624 ) to clamp onto the container  616 . In some examples, the side wall  624  can include an external retaining ring  625  that can rotate relative to (e.g., circumferentially around) the side wall  624 . For example, the retaining ring can be rotated to a higher position to increase the opening  621  and can be rotated to a lower position to decrease the opening. In some examples, the opening  621 , the side wall  624 , and the retaining ring  625  can be operationally associated with gripping latches  627  (e.g., inwardly projecting protrusions or teeth) that are moved out of the way of the opening  621  when the retaining ring  625  is rotated to an up position (e.g., so as not to obstruct the opening), and that can clamp onto the container  616  when the retaining ring is rotated to a lower position. As shown in  FIGS.  8  and  9   , the latches  627  can pivot around an axis to move between a more open configuration (e.g.,  FIG.  8   ), and a clamped configuration (e.g.,  FIG.  9   ). In the sprayer assembly  610 , the latches  627  can mate with the container  616 , and in some examples, the latches  627  can engage a canister for holding a container of fluid (e.g., a coupling mechanism that projects inwardly towards the cavity and is configured to selectively engage the container of fluid, the canister for holding the container of fluid, or any combination thereof.) 
     In some example, the lid  613  can include an internal shoulder  650  that abuts the top rim  651  when the container  616  is fully inserted. In addition, the lid  613  can include a sealing O-ring  642  that creates an airtight seal with the side of the container&#39;s cap  623 . Once the container rim  651  has been fully seated against the device shoulder  650 , the retaining ring  625  can be spun clockwise down its threads to lock the container  616  in place. In addition, the movement of the retaining ring  625  pushes the latches  627  inward and under the can&#39;s top rim. In some examples, catch points  629  on the back of the teeth interfere with the ring  625  when it is at its lowest point to indicate that the device is securely installed. The sprayer-head assembly can be easily transferred or reconfigured to work with many standard industrial fluid containers without concern or working around threading, nozzles, or popped tops. In examples, the latches  627  are spring loading to remain in the open position when not closed by the ring  625 . In addition, the design of the latches  627  can create a negligible moment on the rim when under force. In some instances, based on this feature, if the container is under high pressure and the ring is opened, then teeth will remain attached until the internal pressure is reduced to a safe level. 
     The sprayer assembly  610  can include various other parts, similar to the sprayer assembly  10 , such as a quick release air fitting  618  in the handle  615  that can be connected to air hoses to allow the container  616  and its contents to be pressurized. A bored air channel  655  in the handle  615 , stem  617 , and lid  613  can carry the pressurized air into the container  616 . A check valve  660  can be positioned in the stem  617 , as well as an internal pressure regulator  658  that controls the allowable pressure level of the contents to ensure that the device operates the same even with a variety of input pressures. In at least some examples, an aerosol valve assembly  662  is crimped onto the top of the lid  613  and includes a fluid intake tube of the appropriate length to reach to the bottom of the respective container. In examples, the sprayer assembly  610  can be used with off-the-shelf, pre-filled, non-pressurized fluid containers. As such, a user doesn&#39;t need to handle or pour any fluids which reduces potential hazards from contact and spills. The lack of propellants in the packaging also allows the fluid to sit on shelves longer and transport better. In addition, the air coupling, integrated check valve, and regulator can allow the device to spray product both while connected to a pressurized air hose or disconnected using the built-up internal air pressure. The regulator can be adjusted to vary the output performance of the fluid in relation to the type of actuator used.
