     TECHNICAL FIELD 
     This document pertains generally, but not by way of limitation, to control devices for the limited opening of windows 
     BACKGROUND 
     Accidental falls from elevated windows (for instance, second-floor windows or higher) are a safety concern, especially with young children. For instance, a small child might open a window or go to an already-open window and lean out, lean against a screen, climb out, or the like. The small child could lose his/her balance or the screen could give way, and the child could fall out of the window. Depending on the height of the window above ground level, such a fall could result in injury and/or death. Certain building standards have been developed to require that windows include features to limit the amount that the windows can be opened. For instance, ASTM F2090 addresses window fall prevention devices with emergency escape (egress) release mechanisms.

     DETAILED DESCRIPTION 
       FIG. 1  shows a perspective view of one example of a window assembly  100 . The window assembly  100 , as described herein, is installed in dwellings, commercial buildings, or the like. The views shown herein (e.g.,  FIG. 1 ) are readily reoriented so that the window assembly  100  shown in a vertical orientation is also usable in a horizontal orientation. In an example, the window assembly  100  includes, but is not limited to, a window frame  104 , a first sash  106  (e.g., a top sash), a second sash  108  (e.g., a bottom sash), a lock  110  (e.g., a keeper), and one or more sash limiter assemblies  102 . The first sash  106  is slidably positioned within the window frame  104  and is thereby able to translate within the window frame  104 . In yet another example, the second sash  108  is slidably positioned within the window frame  104  and translates within the window frame  104 . In still another example, one of the first and second sashes  106 ,  108  (the second sash  108  in  FIG. 1 ) are slidably positioned within the window frame  104  while the other sash is fixed within the window frame  104 . Optionally, the first and second sashes  106 ,  108  translate horizontally, for instance, when the window assembly  100  is configured for a horizontal installation. While the examples described herein are provided in the form of a window, in other examples the devices and assemblies described herein are used in other fenestration assemblies including doors (e.g., sliding doors). 
     As described above, in use one or more of the first or second sashes  106 ,  108  translates vertically or horizontally according to the window assembly  100  installation. The lock  110  shown in  FIG. 1  is, in one example, a latch associated with the second sash  108  and is configured for receipt with a keeper coupled with the first sash  106 . The lock  110  fixes the first sash  106  and the second sash  108  and arrests both of the sashes from moving from the closed configuration (shown in  FIG. 1 ). 
     Referring again to  FIG. 1 , in one example, one or more sash limiter assemblies  102  are coupled with the first sash  106  and configured to intercept and selectively prevent full translation of the second sash  108 . In another example, two or more sash limiter assemblies  102  are coupled to the first sash  106  and at least two assemblies  102  are positioned on opposed stiles  206  of the first sash  106 . Two or more sash limiter assemblies  102  are installed on a product for further security, compliance with regulations or the like. Alternatively, the sash limiter assembly  102  is coupled to the window frame  104 . In yet another example, one or more sash limiter assemblies  102  are coupled to the window frame  104  and each is positioned on opposite members of the window frame  104  (e.g., the jambs). 
     The sash limiter assembly  102  is coupled to one or more of the first sash  106 , second sash  108 , the window frame  104  or the like by use of fasteners including, but not limited to, screws, bolts, nails or the like, for instance extending through corresponding fastener apertures of the limiter housing ( 200  as described herein). In another example, the sash limiter assembly  102  is coupled to the first sash  106 , second sash  108 , or the window frame  104  by use of adhesives, welds, mechanical fittings or the like. 
       FIG. 2  is a detailed perspective view of the window assembly  100  of  FIG. 1  in a partially open configuration with the second sash  108  engaged with a sash stop  204  of the sash limiter assembly  102 . As shown in  FIG. 2 , the sash limiter assembly  102  includes, but is not limited to, a limiter housing  200 , a reset  202 , and a sash stop  204 . The sash stop  204  is deployed in  FIG. 2  and intercepts the second sash  108  to prevent further translation (e.g., in the opening direction). As will be described in detail herein, the sash limiter assembly  102  is positioned between a sash limiting configuration and a resetting configuration. As described herein, in the sash limiting configuration the sash limiting assembly  102  prevents the translation of the first and second sash  106 ,  108  beyond a specified opening. As shown in  FIG. 2 , in the sash limiting configuration, the sash stop  204  is in an engaging position within the translation path of the second sash  108 . 
     As will be described herein, in a resetting configuration, the sash limiter assembly  102  allows the second sash  108  to translate past the sash limiter assembly  102 , for instance toward a full open position. Similarly, the first sash  106  is also movable to a fully open position. In the resetting configuration the sash stop  204  is in a retained position such that the sash stop  204  is out of alignment with the translation path of the second sash  108 . The sash stop  204  is optionally held in the retained position by the reset  202  and released from the retained position by movement of the reset  202 . 
     In one example, the sash limiter assembly  102  limits the travel of the first and second sashes  106 ,  108  of the window assembly  100  to meet child fall protection codes. For instance, the sash limiter assembly  102  limits the opening of either the first or the second sash  106 ,  108  to no more than 4 inches when installed at a corresponding position on the window assembly  100 . While in the sash limiting configuration the sash limiter assembly  102  prevents the second sash  108  from opening greater than 4 inches (based on the sash limiter assembly  102  installation). The sash stop  204  of the sash limiter assembly  102  extends from the first sash  106  (as shown in  FIG. 2 ) and also extends above the check rail of the second sash  108  (e.g., from the limiter housing  200 ) and intercepts the second sash  108  or a stop plate  208  on the second sash  108 . To facilitate movement of the first and second sashes  106 ,  108  beyond the sash stop  204  the sash limiter assembly  102  is set to a bypass mode (e.g., the resetting configuration) by a two-step operation to facilitate opening of the sash fully, such as for egress. In yet another example, and as described herein, movement of the sash (e.g., the first or second sash  106 ,  108 ) past the sash limiter assembly  102  in the resetting configuration automatically resets the sash limiter assembly  102  to the sash limiting configuration (releases the sash stop  204 ) and thereby limits opening of either of the sashes  106 ,  108  to the selected opening (e.g., 4 inches) according to the installation of the limiter assembly  102 . 
     Optionally, in the resetting configuration (further shown herein) the sash limiter assembly  102  is substantially flush with the component it is installed with (e.g., a sash, frame portion or the like). In the sash limiting configuration the sash stop  204  projects from the component (e.g., the first sash  106  or frame  104 ). Because the sash limiter assembly  102  is flush or nearly flush in the resetting configuration (e.g., the bypass mode), the sash limiter assembly  102  is used in a wide array of window products having varying offsets and clearances between the first and second sashes  106 ,  108 . Stated another way, the compact shape of the sash limiter assembly  102 , for instance in the resetting configuration, allows for the use of the sash limiter assembly  102  in a variety of windows having differing spacing between interior and exterior sashes (i.e., the first and second sashes  106 ,  108 ). 
       FIG. 3A  is a first exploded view of an example of the sash limiter assembly  102 . The exemplary sash limiter assembly  102  shown includes a sash stop  204  and a reset  202  configured to release the sash stop  204  from the resetting configuration (see  FIGS. 5A , B). Optionally, the sash stop  204  and the reset  202  are housed in a limiter housing  200 , and the limiter housing  200  is fit within a corresponding recess in the window assembly  100  (e.g., within a stile of a sash or a portion of the frame  104 ). In another example, the sash stop  204  and the reset  202  are installed within a recess of the window assembly  100  without the limiter housing  200 . As shown in  FIG. 3A , the sash stop  204  is rotatably coupled with the limiter housing  200  with a stop pivot  304  received within a stop pivot recess  314 . Similarly the reset  202  is rotatably coupled with the limiter housing  200  with a reset pivot  302  received within a reset pivot recess  312 . 
     Referring again to  FIG. 3A , a biasing element  300  is interposed between the sash stop  204  and the limiter housing  200  (or sash or frame component if the housing is absent). The biasing element  300  includes, but is not limited to, a compression spring, torsion spring (e.g., wrapped around the stop pivot  304 ), elastomer or the like. In one example, the biasing element  300  includes, but is not limited to, one or more of steel, stainless steel or the like. The limiter housing  200  includes a recess, cavity or the like to retain an end of the biasing element opposed to the end coupled with the sash stop  204 . In one example, the limiter housing  200  includes, but is not limited to, one or more of zinc, aluminum, a polymer or the like. Optionally, the limiter housing  200  is constructed by way of die casting, injection molding or the like. The sash stop  204  has a corresponding recess within the sash stop  204  to retain an end of the biasing element  300  within the sash stop  204 . During assembly, the biasing element  300  is placed in the limiter housing  200  (e.g., within a recess or cavity in the housing) and the sash stop  204  is coupled with the limiter housing  200  such that the sash stop flange  306  is placed under a housing flange  308  and the biasing element  300  is placed inside the recess within the sash stop  204 . The sash stop pivot  304  is inserted through the stop pivot recess  314  and aligned holes  315  provided on the limiter housing  200 . In one example, the sash stop  204  includes, but not limited to, one or more of zinc, aluminum, a polymer or the like. Optionally, the sash stop  204  is constructed by way of die casting, injection molding or the like 
     The stop pivot  304  in combination with the housing flange  308  retains the sash stop  204  within the limiter housing  200  (e.g., within a limiter cavity  320 ). Additionally, the sash stop  204  is able to rotate about the stop pivot  304 . The biasing element  300  biases the sash stop  204  toward the engaging position (e.g., projected as shown in  FIG. 2 ) with the sash stop  204  within the translation path of the second sash  108 . When the sash stop  204  is in the engaging position, the sash stop flange  306  is engaged with the housing flange  308  and held at the engaging position. Further, the housing flange  308  prevents additional rotation of the sash stop  204  when engaged by the second sash  108  (or a stop plate  208 ) at a sash intercepting face  324  of the sash stop  204 . Stated another way, the housing flange  308  in combination with the sash stop  304  (e.g., the sash stop flange  306 ) locks the sash stop  304  in place and robustly supports the sash stop  304  against further rotation caused by continued movement of the second sash  108 . In another example, the stop pivot  304  provides an additional support point for the sash stop  204  to prevent its displacement as the second sash  108  engages with the sash intercepting face  324 . In one example, the stop pivot  304  includes, but not limited to, one or more of steel, stainless steel or the like. Optionally, the stop pivot  304  is constructed by way of stamping. The combination of the stop pivot  304  and the sash stop flange  306  distribute the load placed on the sash limiter assembly  102 , by the second sash  108 , throughout the limiter housing  200 . In one example, the reset  202  includes, but not limited to, one or more of zinc, aluminum, a polymer or the like. Optionally, the reset  202  is constructed by way of die casting, injection molding or the like. 
       FIG. 3B  is an exploded view of the sash limiter assembly  102  of  FIG. 3A  and shows another side of the sash limiter assembly  102 . As shown, the reset  202  is placed in the void between the sash stop  204  and the stop pivot  304 . The reset pivot  302  is inserted through holes  317  on the limiter housing  200  aligned with the reset pivot recess  312 . The reset pivot  302  provides an axis of rotation for the reset  202 . In one example, the reset pivot  302  includes, but not limited to, one or more of steel, stainless steel or the like. Optionally, the reset pivot  302  is constructed by way of stamping. 
     In one example, the reset  202  has a retaining pin channel  316 . The retaining pin channel  316  is sized and shaped for reception of a stop retaining pin  318  within the retaining pin channel  316 . As shown in  FIG. 3A , the stop retaining pin  318  extends from the sash stop  304 . In another example, the retaining pin channel  316  is located on the sash stop  204 , and the stop retaining pin  318  is located on the reset  202 . As will be described herein, the engagement of the stop retaining pin  318  with the walls of the retaining pin channel  316  facilitates the retention of the sash stop  204  in a depressed position for the resetting configuration. For instance, rotation of the reset  202  to the resetting position (extending from the limiter housing  200 ) forces the sash stop  204  into the limiter housing  200  as the stop retaining pin  318  (and the sash stop  204 ) is forced to travel along the retaining pin channel  316 . The engagement of the retaining pin channel  316  (the channel walls) with the stop retaining pin  318  holds the stop  204  in the retained position with the reset  202  extending upwardly from the housing  200  (and in line with the translation of the second sash  108 ). In one example, the reset  202  includes, but not limited to, one or more of zinc, aluminum, a polymer or the like. Optionally, the reset  202  is constructed by way of die casting, injecting molding or the like 
       FIG. 3C  is a sectional view of the sash limiter assembly  102  of  FIG. 3A . In an example, when the sash limiter assembly  102  is in the sash limiting configuration, the reset  202  is within the limiter cavity  320 . When the user wants to change the sash limiter assembly  102  into the bypass mode, the user depresses the sash stop  204  into the limiter cavity  320  (overcoming the bias of the biasing element  300 ). The depression of the sash stop  204  aligns the retaining pin channel  316  (See  FIG. 3B ) of the reset  202  with the stop retaining pin  318  (See  FIG. 3A ) of the sash stop  204 . Stated another way, the stop retaining pin  318  and the retaining pin channel  316  are out of alignment if the sash stop  204  is not depressed to prevent the reset  202  from rotating about the reset pivot  302  in one example. 
     In another example when the window assembly  100  is in a vertical orientation (as shown in  FIG. 1 ), the reset  202  is loosely coupled with the reset pivot  302  to allow free rotation (e.g., because of gravity). The loose coupling between the reset  202  and the reset pivot  302  allows the reset  202  to automatically move toward the resetting position when the sash stop  204  is depressed into the limiter cavity  320  (e.g., the reset  202  falls and rotates according to gravity). Stated another way, when the sash stop  204  is depressed, the force of gravity will move the reset  202  toward the resetting position. When two or more sash limiter assemblies  102  are installed on a window assembly  100 , the automatic movement of the reset  202  reduces user interaction with the sash limiter assembly  102  while still complying with regulations (e.g., the requirement for two interactions with the window assembly  100  before the second sash  108  or first sash  106  will translate past a specified distance). 
     Alternatively, one or more sash limiter assemblies  102  are installed in a window assembly  100  that is in a horizontal orientation while still complying with regulations. In an example, one sash limiter assembly  102  is installed because the user manually moves the reset  202  into the resetting position (e.g., after depressing the sash stop  204 ). In the horizontal configuration, the user thereby performs two or more operations on the sash limiter assembly  102  to open the second sash  108  (or first sash  106 ) more than a specified distance (based on one or more of installation and in compliance with a regulation). 
     Referring again to  FIG. 3C , when the user rotates the reset  202 , the stop retaining pin  318  (See  FIG. 3A ) moves inside the retaining pin channel  316  (See  FIG. 3B ). In one example, the reset  202  rotates a specified amount (e.g., around 90 degrees) before the stop retaining pin  318  reaches the end of the retaining pin channel  316 . In another example, the reset  202  rotates a specified amount before the reset  202  intercepts a portion of the sash stop  204  (e.g., a top of the depressed sash stop). In yet another example, with the stop retaining pin  318  within the retaining pin channel  316 , the sash stop  204  is held in the depressed position and prevented from rising to the engaging position through bias of the biasing element  300  (i.e., the sash stop is in the retained position). Stated another way, when the reset  202  is rotated and the stop retaining pin  318  is within the retaining pin channel  316 , the sash stop  204  is locked in the retained position and the sash limiter assembly is in the resetting configuration (e.g., the bypass mode). 
     As described in further detail herein, when the sash limiter assembly  102  is in the bypass mode, the sash stop  204  is retained substantially within the limiter cavity  320  (See  FIG. 5B ). In the bypass mode, the sash intercepting face  324  of the sash stop  204  is positioned outside of the translation path of the second sash  108  and the second sash  108  is able to translate past the sash stop  204 . In another example with the sash limiter assembly  102  installed with the second sash  108  or the frame, in the bypass mode the sash intercepting face  324  of the sash stop  204  is positioned outside of the translation path of the first sash  106  and the first sash  106  is able to translate past the sash stop  204 . 
     As described further herein, as the second sash  108  translates past the sash stop  204  (depressed and retained in the limiter cavity  320 ), the second sash  108  engages with and rotates the reset  202 . The second sash  108  rotates the reset  202  and thereby releases the sash stop  204 . Rotation of the reset  202  moves the stop retaining pin  318  out of the retaining pin channel  316  and thereby releases the sash stop  204 . The sash limiter assembly  102  accordingly transitions out of the bypass mode (i.e., the resetting configuration) and the sash stop  204  is biased back toward the engaging position (e.g. projected as shown in  FIG. 2  once the second sash  108  is removed from over top of the sash stop  204 ). 
       FIG. 4A  is a detailed perspective view of the window assembly  100  with the sash limiter assembly  102  in a sash limiting configuration. With the sash limiter assembly  102  in the sash limiting configuration the sash stop  204  is in an engaging position such that the sash intercepting face  324  (See  FIG. 3C ) of the sash stop  204  will intercept the second sash  108  (or the stop plate  208  of the second sash  108 ) with movement of the second sash toward the sash stop. In the sash limiting configuration, the sash limiter assembly  102  prevents the second sash  108  from translating past a certain point (dependent upon installation location). In another example, the sash limiter  102  prevents the second sash  108  from opening greater than 4 inches (based on the sash limiter assembly  102  installation). As described herein, the user is able to translate the second sash  108  a specified distance until the second sash  108  is intercepted by the sash limiter assembly  102  (e.g., after the second sash  108  translates four inches). 
       FIG. 4B  is a sectional view of the window assembly  100  of  FIG. 4A . As described herein, in the sash limiting configuration the sash stop  204  is biased by the biasing element  300  toward the engaging position with the sash stop  204  is positioned in the translation path of the second sash  108 . The bias towards the engaging position is overcome when the user depresses the sash stop  204  into the limiter cavity  320 . In combination with the coupling of the sash stop  204  to the stop pivot  302  ( FIG. 3C ) the engagement of the sash stop flange  306  and the housing flange  308  locks the sash stop  304  in place and robustly supports the sash stop  304  against further rotation otherwise caused by continued movement of the second sash  108 . 
       FIG. 5A  is a detailed perspective view of an example of the window assembly  100  with the sash limiter assembly  102  in the resetting configuration. As described herein, the reset  202  is rotated into the translation path of the second sash  208  under certain conditions, for instance where opening of a sash, such as the second sash  108 , beyond the sash limiter assembly  102  is desired (e.g., for egress). In one example, the reset  202  is rotated when the stop retaining pin  318  is in alignment with the retaining pin channel  316 . As shown in  FIG. 5A , the sash stop  204  is depressed substantially within the limiter cavity  320  (e.g., the sash stop  204  is flush or recessed relative to the outer face of the sash  106 ). With the sash stop  204  depressed, the stop retaining pin  318  and the retaining pin channel  316  are aligned and the reset  202  is rotated from its normal position within the limiter cavity  320  to a resetting position, wherein the reset  202  is in the translation path of the second sash  108 . With the reset  202  moved to the resetting position the sash stop  204  is retained substantially within the limiter cavity  320 . For instance, the rotation of the reset  202  positions the stop retaining pin  318  in engagement with one or more walls of the retaining pin channel  316 . The engagement of the retaining pin channel  316  (the channel walls) with the stop retaining pin  318  holds the stop  204  in the retained position. Optionally, and as discussed herein the stop retaining pin  318  and the retaining pin channel  316  are reversed with the pin on the reset  202  and the channel on the sash stop  204 . In another example other features including, but not limited to, gears, latches, rollers or the like are used between one or more of the reset  202 , the sash stop  204 , the limiter housing  200  (or the sashes or frame) to retain the sash stop  204  in the depressed position while at the same time preparing the sash limiter assembly  102  for resetting with movement of one or more of the sashes  106 ,  108 . 
       FIG. 5B  is a sectional view of the window assembly  100  of  FIG. 5A  with the reset  202  in the resetting position. In an example, the reset  202  in the resetting position places the reset  202  within the translation path of the second sash  108  while the sash stop  204  is retained within the limiter cavity  320 . In the resetting position, the second sash  108  is able to translate past the sash stop  204  (e.g., to provide a large opening) and engages with the reset  202 . In another example, the first sash  106  is able to translate toward an open position (i.e., a larger opening than with the sash stop  204  in the sash limiting configuration). Stated another way, when the sash limiter assembly  102  is in the resetting configuration, one or more of the first or the second sashes  106 ,  108  may be translated past the sash limiter assembly  102  and reset the sash limiter assembly  102  as described herein. 
       FIG. 6A  is a detailed perspective view of the window assembly  100  with the stop plate  208  of the second sash  108  engaged with the reset  202 . As the second sash  108  engages with the reset  202  and continues to move over the sash limiter assembly  102  the reset  202  is moved from its resetting position toward its stowed position within the limiter cavity  320 . In the stowed position reset  202  is disengaged from sash stop  204  to accordingly release the sash stop to project from the limiter housing  200  (e.g., to project from the housing or the sash after disengagement of the sash from over top of the sash stop  204 ). 
       FIG. 6B  is a sectional view of the window assembly  100  of  FIG. 6B . As shown in  FIG. 6A  and shown again in  FIG. 6B , the stop plate  208  of the second sash  108  engages with the reset  202  to move the reset  202  (e.g., rotate the reset) from the resetting position toward the stowed position within the limiter cavity  320 . Rotation of the reset  202  moves the stop retaining pin  318  out of the retaining pin channel  316  (See  FIGS. 3A and 3B ) and thereby releases the sash stop  204  to transition back to the engaging position (shown in  FIGS. 4A , B) after the sash is moved from over top of the sash stop. The sash limiter assembly  102  accordingly automatically transitions out of the bypass mode (i.e., the resetting configuration) and the sash stop  204  is biased back toward the engaging position (e.g. projected as shown in  FIGS. 2, 4A , B) once the second sash  108  is removed from over top of the sash stop  204 . 
     The engagement of the second sash  108  with the reset  202  and movement of the reset  202  by the second sash  108  releases the sash stop  204 . With the sash positioned as shown in  FIGS. 6A , B the sash intercepting face  324  of the sash stop  204  is not engaged with the second sash  108  (and the second sash  108  is not prevented from translating towards the fully open position). Instead, a sash stop ramp  600  of the sash stop  204  slides along the second sash  108  as the second sash  108  travels over the sash limiter assembly  102  (e.g., towards a fully open position or toward the closed position). Once the second sash  106  is removed from over the top of the sash stop  204  (e.g., translated past the sash stop  204  during closing movement), the sash stop  204  moves and projects as shown in  FIG. 2 , for instance according to the bias of the biasing element  300 . 
       FIG. 7A  is a perspective view of an example of a window assembly  100 . The second sash  108  is in a partially open position (e.g., is open greater than the limited position shown in  FIG. 2 ). The second sash  108  is positioned over a portion of the first sash  106  and a lower pane of glass  700  obscures the sash limiter assembly  102  from view. The detail of  FIG. 7A ,  FIG. 7B , shows the pane of glass  700  removed to expose the sash limiter assembly  102 . In an example with the second sash  108  translated past the sash limiter assembly  102  (e.g., after having reset the sash limiter assembly  102  as described herein), the second sash  108  is able to continue translating toward a fully open position, or is able to translate towards the fully closed position. As described above, the sash stop  204 , previously released with movement of the reset  202 , is biased outwardly but fails to interrupt movement of the second sash  108  until the second sash  108  is moved from an overlying position. Stated another way, the sash stop  204  projects to the engaging position once the second sash  108  is moved out of the way. 
     As described above,  FIG. 7B  is a detailed perspective view of the window assembly  100  of  FIG. 7A  with the lower pane of glass  700  removed to show the otherwise obscured sash limiter assembly  102 . As described herein, the second sash  108  translates past the sash limiter assembly  102  once the sash limiter assembly  102  is in the resetting configuration (e.g., the sash stop  204  is depressed, held and then eventually released by the reset  202 ). When the second sash  108  has translated past the sash limiter assembly  102 , the second sash  108  translates freely within the window frame  104  (i.e., towards the fully closed or fully open position) without interception by the sash limiter assembly  102 . The second sash  108  translates freely because the second sash  108  has engaged and moved the reset  202  while the sash stop  204  was retained in the depressed position. While the second sash  108  remains positioned over the released sash stop  204  the sash is able to move freely. The second sash  108  freely translates because the second sash  108  will not engage with the sash intercepting face  324  until the second sash  108  is moved toward the fully closed position and translates past the sash stop  204 . However, once the second sash  108  translates past the sash stop  204 , the sash stop  204  projects outwardly from the limiter housing  200  to the engaging position automatically (e.g., according to the biasing element  300 ). To facilitate opening of the second sash  108  past the sash stop  204  again the user places the sash limiter assembly  102  into the resetting configuration (e.g., by depressing the sash stop  204  and moving the reset  202  to hold the sash stop  204  in the depressed position). 
       FIG. 7C  is a sectional view of the window assembly  100  of  FIG. 7A . As described herein, the second sash  108  is able to translate toward the fully open position or translate toward the fully closed position after movement of the reset  202  and release of the sash stop  204 . As the user translates the second sash  108  from the position shown in  FIG. 7A  toward the fully closed position and past the sash stop (e.g., the top of the second sash passes over the sash stop  204 ) the second sash  108  slides along the sash stop ramp  600  and past the sash stop  204 . Stated another way, when the second sash  108  is in the position shown in  FIG. 7A , the sash stop  204  allows for full opening of the second sash  108  (and the first sash  106 ) toward the fully closed position. It is after passage of the second sash  108  (or first sash  106 ) to uncover or expose the released sash stop  204  and allow the stop to project to the engaged position that further movement of the second sash  108  (or first sash  106 ) is limited. 
       FIG. 8  shows one example of a method  800  for using a sash limiter assembly. In describing the method  800 , reference is made to one or more components, features, functions and steps previously described herein. Where convenient, reference is made to the components, features, steps and the like with reference numerals. Reference numerals provided are exemplary and are not exclusive. For instance, components, features, functions, steps and the like described in the method  800  include, but are not limited to, the corresponding numbered elements provided herein, other corresponding features described herein (both numbered and unnumbered) as well as their equivalents. 
     At step  802  the method  800  includes moving a sash stop  204  from an engaging position within a translation path of either a first or a second sash  106 ,  108  to a retained position out of alignment with the translation path. The translation path of either the first or the second sash  106 ,  108  is the space through which the first or second sash  106 ,  108  moves within the window frame  104 . In an example and as described herein, the sash stop  204  is retained within the limiter cavity  320 . In another example, the sash stop  204  is retained within a recess of the window assembly  100  without the limiter housing  200 . In one example, moving the sash stop  204  includes depressing the sash stop  204  relative to the reset  202 . In another example, moving the sash stop  204  includes rotating the sash stop  204  relative to the reset  202 . In yet another example, moving the sash stop  204  includes aligning a stop retaining pin  318  with a retaining pin channel  316 . 
     At stet  804  the method  800  includes moving a reset  202  to a resetting position after moving the sash stop  204  to the retained position. In one example, at Step  806  the method  800  includes moving the reset  202  within the translation path of either the first or the second sash  106 ,  108  while in the resetting position. In another example, at Step  808  the method  800  includes holding the sash stop  204  in the retained position with the reset  202  while the reset  202  is in the resetting position. In yet another example, moving the reset  202  includes rotating the reset  202  relative to the sash stop  204 . In still yet another example, moving the reset  202  includes moving the reset  202  according to alignment of the stop retaining pin  318  with the retaining pin channel  316 . Alternatively, holding the sash stop  204  in the retained position includes holding the stop retaining pin  318  in the retaining pin channel  316 . As described herein, the stop retaining pin  318  engages with the walls of the retaining pin channel  316 . The engagement of the stop retaining pin  318  with the walls of the retaining pin channel  316  facilitates the retention of the sash stop  204  in a depressed position for the resetting configuration. 
     At step  810  the method  800  includes moving either the first or second sash  106 ,  108  in a first direction (e.g., toward the fully open position) and engaging the reset  202  in the resetting position, the reset  202  is moved from the resetting position by the engagement, movement of the reset  202  from the resetting position releases the sash stop  204 . For instance in one example, the reset  202  extends from the limiter housing  200  and is accordingly in the translation path. The second sash  108  translates and is intercepted by the reset  202 . The reset  202  is rotated toward the limiter housing  200  with continued movement of the second sash  108 . In one example, the rotation of the reset  202  disengages the stop retaining pin  318  from the retaining pin channel and releases the sash stop  204  from the retained position. 
     At step  812  the method  800  includes moving either the first or the second sash  106 ,  108  in a second direction (e.g., towards the fully closed position) different from the first direction, moving the first or second sash  106 ,  108  in the second direction moves the first or second sash  106 ,  108  away from the sash stop  204 . 
     At step  814  the method  800  includes moving the sash stop  204  into the engaging position after release of the sash stop  204  by the reset  202  and moving of either the first or second sash  106 ,  108  away from the sash stop  204 . In an example, the biasing element  300  moves (i.e., biases) the sash stop  204  towards the engaging position. 
     The method  800  includes arresting movement of either the first or second sash  106 ,  108  in the first direction (e.g., towards the fully open position) with the sash stop  204  in the engaging position. For instance, the sash intercepting face  324  of the sash stop  204  engages with the second sash  108  and prevents the further translation (i.e., arrests movement) of either the first or second sash  106 ,  108 .
