Title: Electronic device with adjustable airflow diversion

Abstract:
A portable electronic device is disclosed. The portable electronic device may include a laptop computing device that includes a base portion and a display housing rotationally coupled to the base portion. The base portion includes a fan designed to drive heated air out of the base portion, thus cooling the portable electronic device. A dynamic (movable) air diverter is integrated into the base portion near the fan&#39;s outlet. The air diverter is designed to direct airflow from the fan outlet. Moreover, the air diverter can be repositioned by, for example, rotating the display housing relative to the base portion. As a result of the repositioned air diverter, the airflow from the fan outlet is redirected out of the portable electronic device through a different location. The air diverter can be positioned in different discrete locations, or alternatively, can move continuously with the rotational movement of the display housing.

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims the benefit of U.S. Provisional Application No. 63/056,278, entitled “ELECTRONIC DEVICE WITH ADJUSTABLE AIRFLOW DIVERSION,” filed Jul. 24, 2020, the content of which is incorporated herein by reference in its entirety for all purposes. 
    
    
     FIELD 
     The following description relates to electronic devices. In particular, the following description relates to portable electronic devices with dynamic airflow diversion capabilities. For instance, a laptop computing device may include an airflow diverter (e.g., louver) capable of changing its position based upon the position of a housing part of the laptop computing device, thereby directing (or redirecting) airflow from a fan located in the laptop computing device. As a result, the airflow (e.g., heated exhaust air) can be directed out of the laptop computing device through different openings. For laptop computing devices with a display housing and a base portion, the position of the airflow diverter, and subsequent direction of airflow by the airflow diverter, may depend upon the position/angle of the display housing relative to the base portion. Other considerations, such as the presence of a user, can be used to determine the position of the airflow diverter. 
     BACKGROUND 
     Electronic devices are known to include one or more fans designed to drive heated air away from heat-generating components (within an electronic device) and out of the electronic device. In this regard, the heat-generating components are less susceptible to breakdown or damage. Further, when heat is removed from the electronic device, a user is less likely to be injured (e.g., burned) by the electronic device. 
     In some instances, a structure (e.g., stationary blade) is inserted near the exhaust of the fan(s) such that the structure directs the air from the fan(s) in a particular direction. However, this structure is physically secured to the electronic device in a static matter, i.e., the structure does not move. As a result of the stationary nature of the structure, the direction of flow of the exhaust air is the same regardless of other considerations, such as the position of one housing part relative to another housing part. In this regard, for a laptop that includes a display housing and a base portion with a fan and a structure near the fan&#39;s exhaust, the air exiting the fan&#39;s exhaust flows in the same direction regardless of whether the laptop is in a closed configuration (defined by the display housing positioned over the base portion) or an open configuration (defined by the display housing rotated away from the base portion). The stationary/static nature of the structure may cause heated exhaust air to flow toward the display housing or the user, resulting in an undesired user experience. 
     SUMMARY 
     In one aspect, a portable electronic device is described. The portable electronic device may include a base portion. The portable electronic device may further include a display housing rotationally coupled with the base portion.

     Those skilled in the art will appreciate and understand that, according to common practice, various features of the drawings discussed below are not necessarily drawn to scale, and that dimensions of various features and elements of the drawings may be expanded or reduced to more clearly illustrate the embodiments of the present invention described herein. 
     DETAILED DESCRIPTION 
     Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims. 
     In the following detailed description, references are made to the accompanying drawings, which form a part of the description and in which are shown, by way of illustration, specific embodiments in accordance with the described embodiments. Although these embodiments are described in sufficient detail to enable one skilled in the art to practice the described embodiments, it is understood that these examples are not limiting such that other embodiments may be used, and changes may be made without departing from the spirit and scope of the described embodiments. 
     The following disclosure relates to electronic devices, including portable electronic devices, that include dynamic air diversion mechanisms designed to alter the direction of airflow. The air diversion mechanism may include an air diverter (e.g., louver) or another structure used to redirect airflow expelled by a fan exhaust within the electronic device. Moreover, the air diversion mechanism can rotate/pivot, and thus be repositioned in the electronic device. As a result, the air diversion mechanism causes the airflow (from the fan exhaust) to exit/leave the electronic device through a desired opening in the electronic device. 
     Some considerations for the desired opening include cooling efficiency, position of a housing part (e.g., display housing), and ergonomics. For example, the direction of airflow may depend in part upon a position/configuration of the electronic device. An exemplary embodiment of an electronic device includes a portable electronic device, such as a laptop computing device (or simply, laptop), that includes a base portion and a display housing that is rotationally coupled to the base portion. When the laptop is closed, the display housing covers the base portion. The air diversion mechanism can be positioned to direct air from the fan exhaust (assuming the fan is still running) through a bottom, or lower, opening of the electronic device. In other words, the air diversion mechanism can drive air away from the display housing, and in particular, away from a relatively small gap between the display housing and the base portion. Conversely, when the laptop is open, the display housing is rotated away from the base portion such that the user can interact with the electronic device. In this open position, the air diversion mechanism can be repositioned to direct air from the fan exhaust through a top, or upper, opening of the electronic device. In other words, the air diversion mechanism can drive through an opening between display housing and an upper region of the base portion. This may prevent or reduce the likelihood of user exposure to the airflow from the fan exhaust, which is relatively hot. 
     The detailed description describes several ways in which the air diversion mechanism is controlled. In some exemplary embodiments, the air diversion mechanism is passively driven by intermittent contact/engagement with the display housing. In other exemplary embodiments, the air diversion mechanism is coupled the display housing such that rotational movement of the display housing causes a corresponding (and continuous) movement of the air diversion mechanism. Additionally, in some exemplary embodiments, the electronic device includes one or more sensors that dictate the movement of the air diversion mechanism, and thus contribute to an actively controlled system for controlling the movement of the air diversion mechanism. For instance, the position of the air diversion mechanism is dictated by an input from a sensor, and movement of the air diversion mechanism is controlled by a motor. In these exemplary embodiments, an electronic device may include a temperature sensor that detects the presence of a user. The input provided by the temperature sensor may cause movement of the air diversion mechanism to direct airflow away from the user. Other sensors, such as a capacitive sensor, are possible for the detection/presence of the user in proximity to an electronic device. Alternatively, an electronic device may include an orientation sensor that detects the orientation/position of the display housing relative to the base portion. The input provided by the orientation sensor may cause movement of the air diversion mechanism, and thus direct airflow toward a bottom opening (when the electronic device is closed) or toward an upper opening (when the electronic device is open). 
     These and other embodiments are discussed below with reference to  FIGS. 1-31 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these Figures is for explanatory purposes only and should not be construed as limiting. 
       FIG. 1  illustrates an isometric view of an embodiment of an electronic device  100 , showing electronic device  100  in an open position. As shown, electronic device  100  is a portable electronic device, such as a laptop computing device. In this regard, electronic device  100  may include a display housing  102  rotationally coupled to a base portion  104  by one or more hinges (not shown in  FIG. 1 ). Display housing  102  and base portion  104  may each be formed from metal, such as aluminum or aluminum alloy (as non-limiting examples). As shown, display housing  102  is rotated away from base portion  104 , and electronic device  100  defines an open position. 
     Display housing  102  carries a display  106  designed to present visual information in the form of textual information, still images, and motion (video) images. Base portion  104  may include several input mechanisms, such as a track pad  108 , or touch pad, and a keyboard  110 . Additionally, base portion  104  carries several components. For example, although not shown, base portion  104  may carry processing circuits (integrated circuits, central processing units, graphics processing units), memory circuits, audio speakers, microphones, batteries, fans, and flexible circuitry to couple the components together. Also, base portion  104  includes one or more ports, such as a port  112   a  and a port  112   b . These ports are designed to electrically couple electronic device  100  to an external source (not shown in  FIG. 1 ), such as an external data source, an external power source, and/or a standalone display. Ports  112   a  and  112   b  may each define a port configured for an industry standard, such as Universal Serial Bus (“USB”), including USB-C, as a non-limiting example. 
       FIG. 2  illustrates an isometric view of electronic device  100  shown in  FIG. 1 , showing electronic device  100  in a closed position. As shown, display housing  102  is positioned over base portion  104 , thereby concealing several aforementioned input mechanisms (shown in  FIG. 1 ) of electronic device  100 . 
       FIG. 3  illustrates a plan view of electronic device  100 , showing internal features located in base portion  104 . For purposes of illustration, a housing part of base portion  104  is removed. As shown, electronic device  100  includes a hinge  114   a  and a hinge  114   b  secured with base portion  104 . Hinges  114   a  and  114   b  further couple with display housing  102  (shown in  FIG. 1 ), thereby allowing display housing  102  to rotate. Although not shown, base portion  104  carries several components that generate heat during use, such as integrated circuits, processors, batteries, and the like. In order to cool these (and other) components, base portion  104  includes one or more fans, such as a fan  116   a  and a fan  116   b . Each of fans  116   a  and  116   b  include a fan inlet  118   a  and a fan inlet  118   b , respectively, designed to draw heated air into their respective fans. Fans  116   a  and  116   b  include a fan outlet  120   a  and a fan outlet  120   b , respectively, that provide an exit for their respective fans. 
     In order to direct the heated air exiting the fans, electronic device  100  may include air diversion mechanisms located in base portion  104 . As shown, base portion  104  includes an air diverter  122   a  and an air diverter  122   b . Air diverters  122   a  and  122   b  can act as a louver by directing, or in some cases redirecting, the heated air exiting fans  116   a  and  116   b , respectively, such that the heated air leaves the electronic device  100  though a desired opening(s). Moreover, air diverters  122   a  and  122   b  can be dynamic, or rotatable/movable. In some exemplary embodiments, the position of air diverters  122   a  and  122   b  is based in part on the position/angle of the display housing  102  (shown in  FIG. 1 ) relative to base portion  104 . This will be shown and described below. 
       FIG. 4  illustrates a side view of electronic device  100 , showing several vent openings of electronic device  100 . The side view shown in  FIG. 4  may refer to a rear view of electronic device  100 . As shown, electronic device  100  includes vent grill  124   a  and vent grill  124   b . Each of vent grills  124   a  and  124   b  includes several openings that provide an exit location, or vent, for the heated air. Air diverters  122   a  and  122   b  (shown in  FIG. 3 ) can direct the heated air to the vent grill  124   a  and the vent grill  124   b , respectively, where the heat air can ultimately exit the electronic device  100  through one or more openings (shown below). Also, as shown in the enlarged view, electronic device  100  includes an opening  126   a  and an opening  126   b , thereby allowing electronic device  100  to receive ambient air used to carry heat away from the components of electronic device  100 . 
       FIG. 5  illustrates an isometric of air diverter  122   a . Air diverter  122   a  may include multiple air diversion surfaces, such as an air diversion surface  128   a  and an air diversion surface  128   b . As shown, air diversion surfaces  128   a  and  128   b  are non-parallel to each other. However, in other embodiments (not shown), an air diversion may include parallel air diversion surfaces. Also, air diverter  122   a  includes an opening  130  designed to receive a shaft (not shown in  FIG. 5 ), or alternatively, a shaft through each end of opening  130 . Due in part to the dynamic nature of air diverter  122   a , the shaft(s), when inserted into opening  130 , may define a pivot, or rotation, point for movement of air diverter  122   a . Air diverter  122   b  (shown in  FIG. 3 ) may include any features shown and described for air diverter  122   a.    
       FIG. 6  illustrates a partial cross sectional view of electronic device  100 , showing the relationship between fan  116   a  and air diverter  122   a . As shown, air diverter  122   a  is positioned in proximity to fan outlet  120   a . In this manner, the exhaust air that expelled by fan  116   a  through fan outlet  120   a  and vent grill  124   a  passes to air diverter  122   a , where the exhaust air can be directed in a desired manner based upon the position of air diverter  122   a . For instance, when display housing  102  is in proximity to base portion  104  (as shown in  FIG. 6 ), air diverter  122   a  can direct the exhaust air in a particular direction through electronic device  100 . However, when display housing  102  is rotated away from base portion  104  (in a direction denoted by an arrow  131 ), the rotation of display housing  102  causes an extension  132 , or protrusion, of display housing  102  to contact air diverter  122   a , thereby causing air diverter  122   a  to rotate and direct the air in a different direction through electronic device  100 . This will be shown and described below. Other exemplary embodiments will show and described additional means for initiating movement of air diverters. 
       FIG. 7  illustrates a cross sectional view of electronic device  100 , showing air diverter  122   a  directing air from fan  116   a . As shown, electronic device  100  is in the closed position, and display housing  102  is covering base portion  104 . The closed position may define a “zero angle” between display housing  102  and the base portion  104 , i.e., the angle between display housing  102  and base portion  104  is equal to zero. 
     Base portion  104  includes a housing part  134   a  and a housing part  134   b . In some instances, housing parts  134   a  and  134   b  are referred to as a first housing part and a second housing part, respectively. Display housing  102  and housing part  134   a  can define an opening  136   a , while display housing  102  and housing part  134   b  can define an opening  136   b . In some instances, openings  136   a  and  136   b  are referred to as a first opening and a second opening, respectively. In the closed position of electronic device  100 , air diverter  122   a  is positioned to divert exhaust air (denoted by an arrow) received by fan  116   a  (through vent grill  124   a ) to opening  136   a , and out of electronic device  100  via opening  136   a . Also, although electronic device  100  is in the closed position and in some instances not associated with an operating mode, electronic device  100  may nonetheless be operational, and accordingly fan  116   a  is also operational. For example, at least one instance of electronic device  100  being operational in the closed position is when one or more displays (not shown) are connected to electronic device  100  by ports  112   a  and  112   b  (shown in  FIG. 1 ), and electronic device  100  is in use with an external keyboard and mouse (not shown). 
       FIG. 8  illustrates a cross sectional view of electronic device  100  shown in  FIG. 7 , showing display housing  102  rotated away from base portion  104 . As shown, electronic device  100  is in an open position, and display housing  102  is positioned at an angle θ 1  from base portion  104 . Angle θ 1  is approximately 90 degrees, or at least approximately 90 degrees. Angle θ 1  is an exemplary angle defining an open position, and other angles are possible. For instance, display housing  102  can be further rotated by an angle θ 2 . Angle θ 2  is approximately in the range of 20 to 45 degrees, such that display housing  102  can be rotated away from base portion  104  by an angle of 110 to 135 degrees. 
     The rotation of display housing  102  from the closed position to an open position can cause extension  132  of display housing  102  to engage air diverter  122   a , thereby rotating/moving air diverter  122   a . As shown, display housing  102  is rotated in a counterclockwise manner, which causes a corresponding clockwise rotation of air diverter  122   a . As a result of the rotation of air diverter  122   a , air diverter  122   a  is positioned to direct exhaust air (denoted by an arrow) received by  116   a  (through vent grill  124   a ) to opening  136   b , and out of electronic device  100  via opening  136   b . It should be noted that additional rotation of display housing  102  by, for example, by angle θ 2  will not result in additional contact between extension  132  and air diverter  122   a , and accordingly air diverter  122   a  will not undergo additional rotation. However, rotation/movement of display housing  102  from an open position to the closed position (shown in  FIG. 7 ) causes extension  132  to again engage air diverter  122   a , thereby causing air diverter  122   a  to rotate back to the position shown in  FIG. 7 , and air diverter  122   a  can again direct exhaust air to opening  136   a.    
       FIGS. 7 and 8  show and describe movement for air diverter  122   a  based on movement of display housing  102 . Redirecting heated exhaust air from fan  116   a  through a particular opening based upon the position of display housing  102  relative to base portion  104  offers several advantages. For example, when electronic device  100  is in the closed position (shown in  FIG. 7 ), there is a relatively small air gap between display housing  102  and base portion  104 . As a result, directing exhaust air (by air diverter  122   a ) through opening  136   a  provides a means for directing air away from the small gap defined by display housing  102  and base portion  104 , thereby creating a more efficient exit pathway for the exhaust air. Conversely, in an open position (shown in  FIG. 8 ), air diverter  122   a  is rotated and positioned to direct air through opening  136   b . When electronic device  100  (in particular, housing part  134   a ) is placed on a surface or a user&#39;s lap, the exhaust air is directed away from the surface to provide a more efficient exit pathway, or in the case of the user, the exhaust air is directed away from the user to reduce or prevent injury to the user from the exhaust air. It should be noted that air diverter  122   b  (shown in  FIG. 3 ) can rotate/move in the manner as that shown and described for air diverter  122   a.    
       FIG. 9  illustrates a cross sectional view of an alternate embodiment of an electronic device  200 , showing modifications to a display housing  202  of electronic device  200 . Electronic device  200  may include several features previously shown and described for electronic devices. In addition to display housing  202 , electronic device  200  further includes a base portion  204  rotationally coupled to display housing  202 . Base portion  204  can be defined in part by a housing part  234   a  and a housing part  234   b . Base portion  204  carries a fan  216  (between housing part  234   a  and housing part  234   b ) designed to drive heated air out of electronic device  200 . Additionally, base portion  204  carries an air diverter  222  designed to direct air received by fan  216  that passes through a vent grill  224 . Air diverter  222  can direct air through an opening  236   a  (defined by display housing  202  and housing part  234   a ) or an opening  236   b  (defined by display housing  202  and housing part  234   b ). As shown, electronic device  200  is in the closed position, and air diverter  222  is positioned to drive air (represented by an arrow) through opening  236   a . In order to rotate/move air diverter  222 , display housing  202  may include an extension  232   a  and an extension  232   b . Each of extensions  232   a  and  232   b  is designed to contact air diverter  222  based upon a position/angle of display housing  202  relative to base portion  204 . 
       FIG. 10  illustrates a cross sectional view of electronic device  200  shown in  FIG. 9 , showing display housing  202  rotated away from base portion  204 . The rotation of display housing  202  from the closed position to an open position causes extension  232   a  of display housing  202  to engage air diverter  222 , thereby rotating air diverter  222 . As shown, display housing  202  is rotated in a counterclockwise manner, which causes a corresponding clockwise rotation of air diverter  222 . As a result of the rotation of air diverter  222 , air diverter  222  is positioned to direct air (denoted by arrows) received by fan  216 , via vent grill  224 , through opening  236   a  and opening  236   b  and out of electronic device  200 . As a result of the position of air diverter  222 , electronic device  200  provides two distinct pathways for simultaneous expulsion of exhaust air. 
       FIG. 11  illustrates a cross sectional view of electronic device  200  shown in  FIG. 10 , showing display housing  202  further rotated away from base portion  204 . The additional rotation of display housing  202  (in the counterclockwise direction) to an additional open position causes an additional clockwise rotate of display housing  202  such that extension  232   b  of display housing  202  engages air diverter  222 , thereby further rotating air diverter  222 . As a result of the rotation of air diverter  222 , diverter  222  is positioned to direct air (denoted by an arrow) received by fan  216  through opening  236   b  and out of electronic device  200 . As a result of the position of air diverter  222 , little or no heated exhaust air passes through opening  236   a.    
     It should be noted that clockwise rotation of display housing  202  to the open position (shown in  FIG. 10 ) causes air diverter  222  to rotate back to the position shown in  FIG. 10 , and additional clockwise rotation of display housing  202  to the closed position (shown in  FIG. 9 ) causes air diverter  222  to rotate back to the position shown in  FIG. 9 . 
     The prior embodiments show and describe discrete movements of the air diverter. In other words, the air diverter is designed to move to a particular number of positions. However, in some embodiments, the air diverter is in direct engagement with a structure that is coupled to the display housing. As a result, the air diverter continuously moves in accordance with movement of the display housing.  FIGS. 12-19  show and described embodiments in which the air diverter exhibits continuous movement. Additionally, while electronic devices with a single fan and a single air diverter are shown and described, the embodiments in  FIGS. 12-19  may include at least two fans and at least two air diverters. 
       FIG. 12  illustrates an isometric view of an embodiment of an air diverter  322  and a mount  338  used with  322  air diverter. As shown, air diverter  322  includes an extension  340 , or hook. Air diverter  322  further includes an opening  330  designed to receive a shaft (not shown in  FIG. 12 ), or alternatively, a shaft through each end of opening  330 . Also, mount  338  includes a recess  342 . Mount  338  can be secured with a display housing (shown below) in a manner such that mount  338  engages air diverter  322  at recess  342  and extension  340 , respectively. 
       FIG. 13  illustrates a cross sectional view of an embodiment of an electronic device  300 , showing air diverter  322  and mount  338  (shown in  FIG. 12 ) integrated with electronic device  300 . Electronic device  300  may include several features previously shown and described for electronic devices. As shown, electronic device  300  includes a display housing  302 , and mount  338  is coupled with display housing  302 . The securing means may include adhesives, welding, fastening, or soldering, as non-limiting examples. In addition to display housing  302 , electronic device  300  further includes a base portion  304  rotationally coupled to display housing  302 . Base portion  304  can be defined in part by a housing part  334   a  and a housing part  334   b . Base portion  304  carries a fan  316  (between housing part  334   a  and housing part  334   b ) designed to drive heated air out of electronic device  300 . Additionally, base portion  304  carries an air diverter  322  designed to direct air received by fan  316  that passes through a vent grill  324 . Air diverter  322  can direct air through an opening  336   a  (defined by display housing  302  and housing part  334   a ) and/or an opening  336   b  (defined by display housing  302  and housing part  334   b ). As shown, electronic device  300  is in the closed position, and air diverter  322  is positioned to drive air (represented by an arrow) through opening  336   a.    
     Extension  340  of air diverter  322  is in contact with mount  338  at recess  342  of mount  338 . As a result, the rotation of display housing  302  can influence the position of air diverter  322 . For example,  FIG. 14  illustrates a cross sectional view of electronic device  300  shown in  FIG. 13 , showing display housing  302  rotated away from base portion  304 . As shown, display housing  302  rotates from the closed position to an open position, and mount  338  rotates in accordance with the rotation of display housing  302 . Display housing  302  is rotated in a counterclockwise manner, which causes a corresponding clockwise rotation of air diverter  322 . Due in part to the engagement between mount  338  and air diverter  322 , extension  340  of air diverter  322  moves along recess  342  of mount  338  during rotation of display housing  302  and mount  338 . As a result of the rotation of air diverter  322 , air diverter  322  is positioned to direct air (denoted by arrows) received by fan  316  through opening  336   a  and opening  336   b , and out of electronic device  300 . As a result of the position of air diverter  322 , electronic device  300  provides two distinct pathways for simultaneous expulsion of the exhaust air. 
       FIG. 15  illustrates a cross sectional view of electronic device  300  shown in  FIG. 14 , showing display housing  302  further rotated away from base portion  304 . The additional rotation of display housing  302  in the counterclockwise direction causes additional clockwise rotation of air diverter  322 . In particular, extension  340  of air diverter  322  moves further along recess  342  of mount  338 , thereby causing further clockwise rotation the air diverter  322 . As a result of the rotation of air diverter  322 , air diverter  322  is positioned to direct air (denoted by an arrow) received by fan  316  through opening  336   b  and out of electronic device  300 , and little or no heated exhaust air passes through opening  336   a . It should be noted that clockwise rotation of display housing  302  can cause air diverter  322  to rotate back to the respective positions shown in  FIGS. 13 and 14 . 
       FIG. 16  illustrates an isometric view of an embodiment of an air diverter  422  and a mount  438  used with air diverter  422 . As shown, mount  438  and air diverter  422  include a gear  444   a  and a gear  444   b , respectively. Gears  444   a  and  444   b  may be referred to as a first gear and a second gear, respectively. Air diverter  422  further includes an opening  430  designed to receive a shaft (not shown in  FIG. 16 ), or alternatively, a shaft through each end of opening  430 . Mount  438  can be secured with a display housing (shown below) in a manner such that mount  438  engages air diverter  422  by way of gears  444   a  and  444   b , respectively. 
       FIG. 17  illustrates a cross sectional view of an embodiment of an electronic device  400 , showing air diverter  422  and mount  438  (shown in  FIG. 16 ) integrated with electronic device  400 . Electronic device  400  may include several features previously shown and described for electronic devices. As shown, electronic device  400  includes a display housing  402 , and mount  438  is coupled with display housing  402 . The securing means may include adhesives, welding, fastening, or soldering, as non-limiting examples. In addition to display housing  402 , electronic device  400  further includes a base portion  404  rotationally coupled to display housing  402 . Base portion  404  can be defined in part by a housing part  434   a  and a housing part  434   b . Base portion  404  carries a fan  416  (between housing part  434   a  and housing part  434   b ) designed to drive heated air out of electronic device  400 . Additionally, base portion  404  carries an air diverter  422  designed to direct air received by fan  416  that passes through a vent grill  424 . Air diverter  422  can direct air through an opening  436   a  (defined by display housing  402  and housing part  434   a ) and/or an opening  436   b  (defined by display housing  402  and housing part  434   b ). As shown, electronic device  400  is in the closed position, and air diverter  422  is positioned to drive air (represented by an arrow) through opening  436   a.    
     Also, gear  444   a  of mount  438  is coupled, or in a geared relationship, with gear  444   b  of air diverter  422 . As a result, rotation of display housing  402  can influence the position of air diverter  422 . For example,  FIG. 14  illustrates a cross sectional view of electronic device  400  shown in  FIG. 14 , showing display housing  402  rotated away from base portion  404 . As shown, display housing  402  rotates from the closed position to an open position, and mount  438  rotates in accordance with the rotation of display housing  402 . Based on the coupled/geared relationship between gears  444   a  and  444   b , display housing  402  is rotated in a counterclockwise manner, which causes a corresponding clockwise rotation of air diverter  422 . As a result of the rotation of air diverter  422 , air diverter  422  is positioned to direct air (denoted by arrows) received by fan  416  through opening  436   a  and opening  436   b  and out of electronic device  400 . As a result of the position of air diverter  422 , electronic device  400  provides two distinct pathways for simultaneous expulsion of the exhaust air. 
       FIG. 19  illustrates a cross sectional view of electronic device  400  shown in  FIG. 18 , showing display housing  402  further rotated away from base portion  404 . The additional rotation of display housing  402  (in the counterclockwise direction) to an additional open position causes an additional clockwise rotate of air diverter  422 . In particular, additional counterclockwise rotation of gear  444   a  causes additional clockwise rotation of gear  444   b  of air diverter  422 , thereby causing further clockwise rotation of air diverter  422 . As a result of the rotation of air diverter  422 , air diverter  422  is positioned to direct air (denoted by an arrow) received by fan  416  through opening  436   b  and out of electronic device  400 , and little or no heated exhaust air passes through opening  436   a . It should be noted that clockwise rotation of display housing  402  can cause air diverter  422  to rotate back to the respective positions shown in  FIGS. 17 and 18 . 
       FIG. 20  illustrates an isometric view of an embodiment of an air diverter  522 . As shown, air diverter  522  may include multiple air diversion surfaces, such as an air diversion surface  528   a  and an air diversion surface  528   b . Air diversion surface  528   a  includes a concave surface, while air diversion surface  528   b  includes a convex surface. As a result, air diversion surfaces  528   a  and  528   b  are parallel to each other. Air diverter  522  can be integrated with electronic devices previously shown. For example, air diverters with features shown and described for air diverter  522  can replace air diverter  122   a  and air diverter  122   b  (shown in  FIG. 3 ). Also, air diverter  522  includes an opening  530  designed to receive a shaft (not shown in  FIG. 20 ), or alternatively, a shaft through each end of opening  530 . 
     The prior embodiments show and described movement of the air diverter based upon some physical or mechanical connection or engagement (direct or indirect) between the air diverter and the display housing. As a result, the air diverter is passively driven based on movement of the display housing. However, in some embodiments (shown and described below), the air diverter can be actively driven by means other than engagement by a display housing. 
       FIG. 21  illustrates a schematic diagram of an alternate embodiment of an electronic device  600 , showing additional features used to drive an air diverter  622  of electronic device  600 . Electronic device  600  may include several features previously shown and described for electronic devices. For example, electronic device  600  may include a display housing  602  and a base portion  604  rotationally coupled to display housing  602 . Electronic device  600  may further include a fan  616  located in base portion  604 . Air diverter  622  may include at least one air diverter shown in prior embodiments for an electronic device. 
     Also, electronic device  600  includes a processor  648  designed to execute one or more programs or algorithms stored on memory  650 , which may include Random-Access Memory (“RAM”) or Read-Only Memory (“ROM”). Electronic device  600  may further include a sensor  652 . In some embodiments, sensor  652  is a temperature sensor, such as a thermistor or a thermocouple (as non-limiting examples). Sensor  652  is located in base portion  604 . In particular, sensor  652  may be located at or near an exterior surface of base portion  604 . In this manner, when sensor  652  is a temperature sensor, sensor  652  can determine the temperature of the exterior surface of base portion  604 , and provide temperature information to processor  648 . Processor  648  can determine the presence of a user by comparing the temperature, as determined by sensor  652 , with a temperature range commonly associated with a human being. Accordingly, processor  648  can determine, using the temperature, that electronic device  600  is positioned on the user, such as the user&#39;s lap. 
     When a determination is made by processor  648  that electronic device  600  is on the user&#39;s lap, it is generally beneficial to ensure the heated exhaust air is directed out of electronic device  600  away from the user. In this regard, electronic device  600  may further include a motor  654  connected to air diverter  622 . Motor  654  may include a direct current (“DC”) motor, including a brushless DC motor or a stepper motor (as non-limiting examples). When processor  648  determines electronic device  600  is positioned on the user, processor  648  can command/instruct motor  654  to rotate/move air diverter  622  in a manner such that air diverter  622  will direct heated exhaust air from fan  616  out of electronic device  600  away from the user. Alternatively, sensor  652  can monitor the temperature of one or more components (not shown in  FIG. 21 ) within base portion  604 , and processor  648  can use the temperature information from sensor  652  to control motor  654  to direct air diverter  622  in a particular manner, such as away from the user. 
       FIG. 22  illustrates a cross sectional view of electronic device  600  shown in  FIG. 21 , showing air diverter  622  and sensor  652  integrated with electronic device  600 . As shown, base portion  604  is defined in part by a housing part  634   a  and a housing part  634   b . Base portion  604  carries a fan  616  (between housing part  634   a  and housing part  634   b ) designed to drive heated air out of electronic device  600 . 
     Air diverter  622  is designed to direct air received by fan  616  that passes through a vent grill  624 . Air diverter  622  can direct air through an opening  636   a  (defined by display housing  602  and housing part  634   a ) and/or an opening  636   b  (defined by display housing  602  and housing part  634   b ). In this regard, air diverter  622  is connected to a shaft  656  that is coupled to motor  654  (shown in  FIG. 21 ). Sensor  652  is integrated with housing part  634   a  in a manner such that when sensor  652  includes a temperatures sensor, sensor  652  can determine the temperature of an exterior surface of housing part  634   a  and provide the temperature information to processor  648  (shown in  FIG. 21 ). Motor  654 , when directed by processor  648  (shown in  FIG. 21 ), can drive shaft  656 , which in turn rotates/moves air diverter  622 . Unlike prior embodiments, air diverter  622  is driven by motor  654 . As shown by the dotted lines, air diverter  622  can be positioned in one of several positions based on motor  654 . Accordingly, electronic device  600  provides an air diverter  622  that is actively controlled, and the position of air diverter  622  is not specifically dependent upon the position of display housing  602 . 
     While electronic device  600  is in the closed position, it may be beneficial to position air diverter  622  such that the heated exhaust air is driven through opening  636   a  so as to provide a relatively fast and efficient exit for the heated exhaust air out of electronic device  600 . Alternatively, it may be beneficial to ensure the air is directed to opening  636   b  and away from the user of electronic device  600 , particularly when electronic device  600  is positioned on the user. 
       FIG. 23  illustrates a cross sectional view of electronic device  600  shown in  FIG. 22 , showing display housing  602  rotated away from base portion  604 . As shown, display housing  602  rotates from the closed position to an open position. Despite the open position, air diverter  622  can be positioned in one of several positions, as indicated by the dotted lines, based on motor  654  (shown in  FIG. 21 ) driving shaft  656 , which in turn rotates air diverter  622 . While electronic device  600  is in the open position, it may be beneficial to position air diverter  622  such that the heated exhaust air from fan  616  is driven through opening  636   b  to ensure the air is directed away from the user of electronic device  600 , particularly when electronic device  600  is positioned on the user. Alternatively, it may be beneficial to position air diverter  622  such that the heated exhaust air is driven through opening  636   a  and opening  636   b  to provide the heated exhaust air multiple pathways for exiting electronic device  600 . Still further, it may be beneficial to position air diverter  622  such that the heated exhaust air is driven through opening  636   a  such that the heated exhaust air does not extend to, or interfere with, a display (not shown in  FIG. 23 ) carried by display housing  602 . 
       FIG. 24  illustrates a schematic diagram of an alternate embodiment of an electronic device  700 , showing additional features used to drive an air diverter  722  of electronic device  700 . Electronic device  700  may include several features previously shown and described for electronic devices. For example, electronic device  700  may include a display housing  702  and a base portion  704  rotationally coupled to display housing  702 . Electronic device  700  may further include a fan  716  located in base portion  704 . Air diverter  722  may include at least one air diverter shown in prior embodiments for an electronic device. Also, electronic device  700  includes a processor  748  designed to execute one or more programs or algorithms stored on memory  750 , which may include Random-Access Memory (“RAM”) or Read-Only Memory (“ROM”). Electronic device  700  may further include a sensor  752 . In some embodiments, sensor  752  is an orientation sensor, such as an accelerometer or a geomagnetic sensor (as non-limiting examples). Sensor  752  is located in display housing  702 . In this manner, when sensor  752  is an orientation sensor, sensor  752  can determine the position/angle of display housing  702  relative to base portion  704 , and provide orientation information to processor  748 . 
     Electronic device  700  may further include a motor  754  connected to air diverter  722 . Motor  754  may include a direct current (“DC”) motor, including a brushless DC motor or a stepper motor (as non-limiting examples). When processor  748  determines the angle of display housing  702  relative to base portion  704 , based upon sensor  752 , processor  748  can determine whether the electronic device  700  is in the closed position or the open position, both of which are previously described. Based on the position of display housing  702 , it is generally advantageous to orient/position air diverter  722  to direct heated exhaust air from fan  716  in a particular direction. For example, when processor  748  determines electronic device  700  is positioned on the user, processor  748  can a command to motor  754  to rotate/move air diverter  722  in a manner such that air diverter  722  will direct heated exhaust air from fan  716  out of electronic device  700  away from the user. 
       FIG. 25  illustrates a cross sectional view of electronic device  700  shown in  FIG. 24 , showing air diverter  722  and sensor  752  integrated with electronic device  700 . As shown, base portion  704  is defined in part by a housing part  734   a  and a housing part  734   b . Base portion  704  carries a fan  716  (between housing parts  734   a  and  734   b ) designed to drive heated air out of electronic device  700 . 
     Air diverter  722  is designed to direct air received by fan  716  that passes through a vent grill  724 . Air diverter  722  can direct air through an opening  736   a  (defined by display housing  702  and housing part  734   a ) and/or an opening  736   b  (defined by display housing  702  and housing part  734   b ). In this regard, air diverter  722  is connected to a shaft  756  that is coupled to motor  754  (shown in  FIG. 24 ). Sensor  752  is integrated with display housing  702  in a manner such that when sensor  752  includes an orientation sensor, sensor  752  can provide orientation information of display housing  702  to processor  748  (shown in  FIG. 24 ). Motor  754 , when directed by processor  748  (shown in  FIG. 24 ), can drive shaft  756 , which in turn rotates/moves air diverter  722 . Similar to air diverter  622  (shown in  FIG. 22 ), air diverter  722  is not driven by contact with display housing  702 , but by motor  754 . As shown by the dotted lines, air diverter  722  can be positioned in one of several positions based on motor  754 . Accordingly, electronic device  700  provides an air diverter  722  that is actively controlled, and the position of air diverter  722  is not specifically dependent upon the position of display housing  702 . 
       FIG. 26  illustrates a cross sectional view of electronic device  700  shown in  FIG. 25 , showing display housing  702  rotated away from base portion  704 . As shown, display housing  702  rotates from the closed position to an open position. Despite the open position, air diverter  722  can be positioned in one of several positions, as indicated by the dotted lines, based on motor  754  (shown in  FIG. 24 ) driving shaft  756 , which in turn rotates air diverter  722 . While electronic device  700  is in the open position, it may be beneficial to position air diverter  722  such that the heated exhaust air from fan  716  is driven through opening  736   b  to ensure the air is directed away from the user of electronic device  700 , particularly when electronic device  700  is positioned on the user. Alternatively, it may be beneficial to position air diverter  722  such that the heated exhaust air is driven through opening  736   a  and opening  736   b  to provide the heated exhaust air multiple pathways for exiting electronic device  700 . Still further, it may be beneficial to position air diverter  722  such that the heated exhaust air is driven through opening  736   a  such that the heated exhaust air does not extend to, or interfere with, a display (not shown in  FIG. 26 ) carried by display housing  702 . 
       FIG. 27  illustrates a schematic diagram of an alternate embodiment of an electronic device  800 , showing additional features used to drive an air diverter  822  of the electronic device  800 . Electronic device  800  may include several features previously shown and described for electronic devices. For example, electronic device  800  may include a display housing  802  and a base portion  804  rotationally coupled to display housing  802 . Electronic device  800  may further include a fan  816  located in base portion  804 . Air diverter  822  may include at least one air diverter shown in prior embodiments for an electronic device. 
     Also, electronic device  800  includes a processor  848  designed to execute one or more programs or algorithms stored on memory  850 , which may include Random-Access Memory (“RAM”) or Read-Only Memory (“ROM”). Electronic device  800  may further include a button  858 . In some embodiments, button  858  is part of a keyboard (not shown in  FIG. 27 ) or a separate button from the keyboard. Button  858  can include a mechanical button or a capacitive sensing input button (as non-limiting examples). Button  858  can be carried by the base portion  804 . However, in some embodiments (not shown), button  858  is carried by display housing  802 . Button  858  can be operated by a user to control the position of air diverter  822 , and accordingly, control the exit location of heated exhaust air (from fan  816 ) out of electronic device  800 . As shown, button  858  can provide an input to processor  848 , which in turn can command motor  854  to rotate/move air diverter  822 . 
     The prior embodiments show and describe air diverters used to direct heated exhaust air. However, in some embodiments, an electronic device may include air diverters at both air exhaust and intake locations.  FIG. 28  illustrates a plan view of electronic device  900 , showing internal features showing air diverters at both air intake and air exit locations of electronic device  900 . Electronic device  900  may include any features previously described for an electronic device. As shown, electronic device  900  includes a base portion  904 . For purposes of illustration, a housing part of base portion  904  is removed. Base portion  904  includes a fan  916   a  and a fan  916   b . Base portion  904  further includes an air diverter  922   a  and an air diverter  922   b  designed to direct heated exhaust air exiting fans  916   a  and  916   b , respectively. 
     Additionally, base portion  904  includes an air diverter  922   c . However, air diverter  922   c  is designed to direct and regulate ambient airflow into base portion  904  from an opening (not shown in  FIG. 28 ). In order to direct airflow entering base portion  904 , air diverter  922   c  can rotate/move in a manner similar to previous embodiments of air diverters described herein. In order to regulate (e.g., allow, limit, or prevent) ambient airflow into base portion  904 , air diverter  922   c  can rotate/move to block, partially block, or permit the ambient airflow into base portion  904 . Each of air diverters  922   a ,  922   b , and  922   c  may be in proximity to a vent grill, similar to vent grills  124   a  and  124   b  (shown in  FIG. 5 ). Accordingly, air diverter  922   c  may regular airflow received through its respective vent grill (not shown in  FIG. 28 ). 
     The base portion  904  may include a heat-generating component  960 , such as an integrated circuit (as a non-limiting example). As shown, heat-generating component  960  is in proximity to an opening  926  of base portion  904 , with opening  926  also designed as an ambient air intake location of base portion  904 . In some instances, it may be advantageous to position air diverter  922   c  to block ambient air into electronic device  900 , thereby causing ambient air to be drawn into base portion  904  (by the fan  916   a ) via opening  926 . For example, when heat-generating component  960  is operating in a relatively high power mode (thereby generating a relatively high amount of heat), or when a temperature sensor (not shown in  FIG. 28 ) in base portion  904  determines heat-generating component  960  achieves or exceeds a threshold temperature, air diverter  922   c  can be positioned/rotated block ambient air into electronic device  900 , this forcing the ambient air into electronic device  900  via opening  926 . Conversely, when heat-generating component  960  is operating in a low power mode (thereby generating a relatively low amount of heat), or when a temperature sensor in base portion  904  determines heat-generating component  960  is a threshold temperature, air diverter  922   c  can be positioned/rotated to permit air into base portion  904  such that both air diverter  922   c  and/or opening  926  can provide an ambient air intake location. 
     Additionally, the position of air diverter  922   c  may be depend upon the position of air diverters  922   a  and  922   b , or vice versa. For instance,  FIG. 29  illustrates an isometric view of air diverters  922   a  and  922   c  shown in  FIG. 28 , showing movement of air diverters  922   a  and  922   c . As shown, air diverters  922   a  and  922   c  can take opposing positions. For example, air diverter  922   c  is in a “down” position while air diverter  922   a  is in an “up” position. In an alternate configuration (not shown in  FIG. 29 ), air diverter  922   c  is in an “up” position while air diverter  922   a  is in a “down” position. This may prevent air diverter  922   c  from intaking relatively hot exhaust air directed out of electronic device  900  (shown in  FIG. 28 ) via air diverter  922   a.    
       FIG. 30  illustrates a block diagram showing a method  1000  for cooling a portable electronic device, in accordance with some described embodiments. The steps of method  1000  may be implemented by electronic devices described herein. 
     In step  1002 , a fan drives air within the portable electronic device. The air may include ambient air drawn into the portable electronic device by the fan. The fan may include a fan inlet and a fan outlet. In this regard, the air can be used to draw heat away from one or more heat-generating components within the portable electronic device. Accordingly, the ambient air can become heated exhaust air driven through the fan. 
     In step  1004 , the air is directed, by an air diverter, in a first direction. The air diverter may receive air from the fan via the fan outlet. The air may include the heated exhaust air. The first direction may be associated with a direction from the air diverter to an opening formed in the portable electronic device. 
     In step  1006 , the display housing receives a force that causes the display housing to rotate relative to the base portion. The force can rotate the display housing away from the base portion such that the portable electronic device transitions from a closed position to an open position. Conversely, the force can rotate the display housing away from the base portion such that the portable electronic device transitions from the open position to the closed position. 
     In step  1008 , the air diverter is moved, based on the force to the display housing, to define a moved air diverter. In this regard, the air diverter can rotate/move based on rotation of the display housing. In some instances, the air diverter rotates based upon engagement with, or contact by, the display housing. In some instances, the air diverter is coupled with (directly or indirectly) the display housing such that rotation of the display housing causes a corresponding rotation of the air diverter. 
     In step  1010 , the air is directed in a second direction, based upon the moved air diverter. The second direction can be different from the first direction. For instance, the first direction can be associated with a direction toward a first opening of the portable electronic device, and the second direction can be associated with a direction toward a second opening of the portable electronic device. Alternatively, the second direction can be defined by the air diverter positioned to direct air to both the first opening and the second opening of the portable electronic device.
