Description:
TECHNICAL FIELD 
     The described embodiments relate generally to portable electronic devices. More particularly, the present embodiments relate to an improved housing for portable electronic devices to protect them from shock and other elements. 
     BACKGROUND 
     Portable electronic devices such as smartphones, tablets, laptop computers and the like have become ubiquitous in recent years. Users carry these devices while travelling in automobiles, on buses, trains, and on airplanes. Because users have grown accustomed to carrying these devices, many users carry these devices while engaging in strenuous activities such as running, climbing and the like. Because users are in possession of these devices in many environments, they are sometimes dropped or otherwise exposed to shock events involving rapid acceleration or deceleration. In addition, these devices may sometimes be exposed to elements such as water and may even be dropped into water environments such as a lake, ocean, or even a bathtub or sink within the home. 
     By subjecting the portable electronic devices to shock and environmental conditions such as those described above, users risk damage to the electronics in these devices and/or damage to the housing containing these electronics. Such damage can result in poor or no performance of the portable electronic device and/or diminution of the aesthetic appeal of the exterior of such devices. In a situation where the portable electronic device is dropped into water, the user may face a risk not only of irreparably damaging the device due to water ingress, but also of losing the device altogether as these devices will sink, and, depending upon the depth and clarity of the water, the portable electronic device may become unrecoverable. 
     Some modern portable electronic devices incorporate an accelerometer into the device for various purposes. An accelerometer is a device that can measure the force of acceleration, whether caused by gravity or by movement. Conceptually, an accelerometer behaves as a damped mass on a spring. When an accelerometer experiences a change in movement, the mass is displaced to the point that the spring is able to accelerate the mass at the same rate as the casing. The displacement is then measured to give the acceleration. An accelerometer can therefore measure the speed of movement of an object it is attached to. Piezoelectric, piezoresistive and capacitive components are commonly used to convert the mechanical motion into an electrical signal. 
     Because an accelerometer senses acceleration due to movement and gravity, the angle at which a device incorporating an accelerometer can be determined. Accelerometers are increasingly being incorporated into personal electronic devices to detect the orientation of the device, or portions of a device such as, for example, a display screen. The motion and angle of the device is noted by the sensors or a processing unit receiving information from the sensors, so the device can know the orientation of the screen with respect to a gravity vector. 
     SUMMARY 
     Embodiments described herein provide an improved housing for portable electronic devices to protect them in the event of an unexpected shock due to having been dropped by a user or in the event of having been dropped into a water environment. The improved housing includes shock absorbers which may be deployed to protect the device and the housing from damage due to an unexpected acceleration such as from having been dropped. In one embodiment, the shock absorbers are deployed from one or more corners of the devices in order to absorb the shock from the fall. 
     In another embodiment, the shock absorbers may include buoyant material which permits the portable electronic device to float in the event that it is dropped or otherwise exposed to a water environment. By enabling the device to float, this may permit the user time to retrieve the device from the water environment and prevent damage. In addition, by enabling the device to float, it is prevented from sinking to the bottom of a lake, ocean or other turbid waters where retrieval may be problematic. 
     In one embodiment, the shock absorbers on the portable electronic device are contained within the housing and only deployed when rapid acceleration is detected by an accelerometer within the portable electronic device indicating that the movement being experienced by the device is inadvertent due to a drop or other unforeseen event. The shock absorbers may be retractable such that, after deploying in the event of a drop, they may be retracted by a user into the housing and may be later deployed again if necessary. In another embodiment, the shock absorbers may include replaceable pads if the pads have deteriorated due to age or have become worn and less aesthetically pleasing to the user. In the event of a water landing, the user may decide to replace the pads for hygienic or other reasons.

     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. 
     The following disclosure relates to a housing for a portable electronic device incorporating shock absorbers that automatically deploy when a particular acceleration event is detected, such as when the portable electronic device has been dropped. In order to prevent damage to the portable electronic device and, in particular to the housing, the housing includes shock absorbers that are deployed by an accelerometer that senses the dropping event. The shock absorbers may take the form of a variety of protrusions, projections, bumpers, and the like. 
     These and other embodiments are discussed below with reference to  FIGS. 1-10 . 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 a conventional portable electronic device, here taking the form of a smartphone  11 . As should be expressly understood, the portable electronic device could be a tablet, laptop, media player, wearable device or other portable electronic device as the embodiments disclosed herein are not limited to a smartphone but are described with respect to a smartphone for ease of illustration. Smartphone  11  includes a housing  12  and an accelerometer  13  which is contained within housing  12 . Housing  12  also includes a screen  14  and various control inputs  15  adjacent screen  14  or along edges  10  as is known in the art. In one embodiment, accelerometer  13  may be a free fall sensor. 
     In one particular embodiment,  FIG. 2  illustrates a smartphone  11  which includes a housing  12 , accelerometer  13 , screen,  14  and controls  15  as with the smartphone of  FIG. 1 . However, smartphone  11  in  FIG. 2  includes shock absorbers  16  located at the corners of housing  12 . While shock absorbers  16  are preferably located at the corners  19  of housing  12 , it should be expressly understood that shock absorbers  16  could be located along the edges  10  of housing  12  without departing from the scope of the embodiments described herein. Shock absorbers  16  could also be located adjacent screen  14  on the face and/or on the backside of housing  12  instead of along the edges  17  or corners  19  of housing  12 . Shock absorbers  16  are shown in a retracted position in  FIG. 2  but, as will be described herein, they have the capability to extend away from housing  12  in certain situations depending upon sensed conditions. 
     An accelerometer may be used as a free-fall sensor. One example free-fall sensor is used to detect if an attached device has been dropped and is falling. This device is included in the many common computer and consumer electronic products that are produced by a variety of manufacturers. The length of time in free fall may be used to calculate the height and velocity of movement and thus to make a determination whether the device has been dropped or merely set down by a user. Some portable electronic devices may turn themselves off if they sense a lack of movement for a predetermined length of time. Alternative sensors that may be used to detect free fall include gyroscopic sensors, magnetometers, cameras, microphones (for example, through echolocation in coordination with a speaker), and other sensors capable of determining at least one of motion, acceleration, and velocity. Certain sensors may also, or alternatively, detect a distance to an impact surface. Thus, references to an accelerometer herein should be understood to cover other types of sensors with suitable detection functionality, as well. 
     A control device  9  may execute instructions and carry out operations associated with portable electronic devices as are described herein. Using instructions from device memory, controller  9  may regulate the reception and manipulation of input and output data between components of the electronic device. Controller  9  may be implemented in a computer chip or chips. Various architectures can be used for controller  9  such as microprocessors, application specific integrated circuits (ASICs) and so forth. Controller  9  together with an operating system may execute computer code and manipulate data. The operating system may be a well-known system or a special purpose operating system or other systems as are known in the art. Control device  9  may include memory capability to store the operating system and data. Control device may also include application software to implement customized functions associated with the portable electronic device. 
     Referring to  FIG. 3 , smartphone  11  is shown with shock absorbers  16  extended away from housing  12  in a deployed position. That is, shock absorbers  16  have been deployed by smartphone  11  due to a sensed condition by accelerometer  13  which has sensed that smartphone  11  has been dropped or otherwise subjected to an acceleration exceeding a threshold as will be described further herein. Shock absorbers  16  include a cover structure  17  which is connected to retractable supports  18  retractably connected to the four corners  19  of housing  12 . Supports  18  may be spring loaded such that pressure exerted by a user on cover structure  17  toward the corner  19  of housing  12  will cause shock absorbers  16  to move toward corners  19 . Thus, after deployment of shock absorbers, a user may manually retract shock absorbers  16  for re-use in the event of another triggering event. Additionally, it should be noted that the shock absorbers and related structure of this and other embodiments may be incorporated into a case or cover for an electronic device, instead of the device itself. 
     Referring to  FIG. 4 , one corner  19  of smartphone housing  12  is shown in greater detail. Shock absorber  16  is shown in a deployed position extended from housing  12  by retractable supports  18 . Shock absorbers  16  are moveable toward and away from housing  12  as indicated by arrows  20 . Supports  18  may be made of rigid material with the capability to extend into and out of housing  12 . Positions  21 , shown in phantom in  FIG. 4 , show the position of rigid supports  18  when shock absorbers  16  are in a retracted position prior to being deployed. A detent  22  may engage supports  18  when in a retracted position to hold supports  18  inside of housing  12 . When a deployment situation is sensed by accelerometer  13 , detents  22  are moved away from supports  18  by a triggering switch  23  and a spring loaded force pushes supports  18  outward and away from housing  12  such that shock absorbers are in the deployed position shown in  FIG. 4 . In an alternate embodiment, supports  18  could be telescopic such that they do not extend into positions  21  in housing  12  but are located on the exterior of housing  12  at corners  19  and connected to triggering switch  23 . Triggering switch  23  is connected to controller  9  which determines when a triggering event occurs due to a possible impact and then signals triggering switch  23  to deploy shock absorbers  16 . In this embodiment, supports  18  are compressed when shock absorbers are in a retracted position to allow shock absorbers  16  to retract into corner  19 . Bumper cushions  24  are shown adjacent to cover structure  17  as will be described further herein with respect to  FIG. 5  and the other figures. 
     Referring to  FIG. 5 , corner  19  of housing  12  is again shown as in  FIG. 4  but with bumper cushions  24  extended from cover structure  17 . Bumper cushions  24 , as described previously, are retractably connected by spring-loaded rods  25  to cover structure  17 . Bumper cushions  24  may thus move toward and away from cover structure  17  as indicated by arrows  26  such that, when triggering switch  23  deploys shock absorbers  16  in response to a signal from accelerometer  13 , bumper cushions  24  extend away from cover structure  17  as shown in  FIG. 5 . Bumper cushions  24  will thus absorb at least a portion of the impact of smartphone  11  when smartphone  11  is dropped. 
     Bumper cushions  24  may be made from resilient foam, plastic, rubber, or other suitable cushioning material with sufficient resiliency to absorb the shock impact of smartphone  11  hitting a surface. In addition or alternatively, the spring-loaded rods  25  may absorb at least a portion of the energy generated by the device impacting a surface. In such an embodiment, the bumper cushions may be made of a stiff or rigid material. As yet another alternative, the bumper cushions  24  may be stiff or rigid and may be designed to crack or otherwise fail in the event of an impact, or the rods  25  may be so designed. The failure of the cushions and/or rods may absorb sufficient kinetic energy to avoid damaging the associated device (such as the smartphone). 
     In one embodiment, and as described below, bumper cushions  24  are made from a buoyant material such that smartphone  11  may be made to float if dropped or inadvertently placed into a water environment. In one embodiment, bumper cushions  24  may be removable from supports  25  such that they may be replaced if worn or wet or replacement is otherwise desired by a user. For example, in the event of a water landing, bumper cushions  24  may become wet and a user may decide to replace them or to remove them to allow them to dry apart from smartphone  11 . 
     Bumper cushions  24  may be colored or otherwise configured in a decorative mode such that they add to the appearance of smartphone  11  or blend into the edge or body of the device, thereby making them less obtrusive. 
     As with supports  18  described above, rods  25  may be spring loaded such that when they are extended in the position shown in  FIG. 5 , they may also be retracted by a user in a direction indicated by arrows  26  toward cover structure  17 . As with supports  18 , in an alternate embodiment, rods  25  could be telescoping rods to allow manual retraction of pads  26  against cover structure  17  as was described above. A detent (which may be similar to detent  22 ), may secure rods  25  in a retracted position such that pads  26  are held in place against cover structure  17  as is shown in  FIG. 4  in a non-deployed position. That is, upon receiving a signal from controller  9  in response to a triggering condition, triggering switch  23  releases detents  22  to allow cover structure  17  to move away from corner  19  and then allow bumper cushions  24  to slide out from cover structure  17  such that bumper cushions  24  receive the force of any impact of smartphone  11  with a surface instead of housing  12 . 
     Referring to  FIG. 6 , a side view of smartphone  11  is shown including housing  12 . Shock absorbers  16  are shown in a fully deployed position away from corners  19 . That is, cover structure  17  has moved away from corners  19  and bumper cushion pads  24  have moved away from cover structure  17  by the action of spring loaded rods  25  in the direction indicated by arrows. Detents  27  may be used to secure bumper pads  24  against cover structure  17  in a retracted position as shown in  FIG. 2  but, upon receiving an activation signal from controller  9  in response to accelerometer  13 , detents  27  are simultaneously or subsequently released allowing bumper pads  24  to be extended away from cover structure  17  in the direction indicated by arrows  28  into the position shown in  FIGS. 5 and 6 . In this position, shock absorbers  16  protect smartphone  11  and housing  12  from damage that may occur due to impacts with various surfaces. 
     Referring to  FIG. 7 , a portable electronic device such as smartphone  11  is held in the hand of a user  29 . User  29  may interact with smartphone  11  through screen  14  and controls  15  as is known in the art. Controller  9  and accelerometer  13  are contained within the housing  12  of smartphone  11 . Smartphone  11  includes shock absorbers  16  located at the corners of housing  12 . Shock absorbers  16  are shown in a retracted position in  FIG. 7  but, as will be described above, they have the capability to extend away from housing  12  in certain situations depending upon sensed conditions. More particularly, shock absorbers  16  may be deployed if controller  9  determines that a triggering event has been sensed by accelerometer  13  as will be described below. 
     Referring to  FIG. 8 , a user  31  is standing on a surface which may be a sidewalk  32 . In this embodiment, user  31  has dropped smartphone  11  from his hand  29  and smartphone  11  is falling toward sidewalk  32 . (For purposes of simplicity, the smartphone itself is shown as an in an expanded size in  FIG. 8 , so that various mechanisms of the device may be more clearly seen; the device is not to scale.) Accelerometer  13  in smartphone  11  has sensed this fall and shock absorbers  16  have been fully deployed as described above prior to smartphone  11  making contact with sidewalk  32 . In one embodiment, controller  9  calculates the drop time sensed by accelerometer  13  as will be described herein. In the embodiment shown in  FIG. 8 , the distance from user&#39;s hand  29  to sidewalk  32  is approximately 1.5 meters as shown by arrows  33  in  FIG. 8 . The gravitational attraction between smartphone  11  and earth as represented by sidewalk  32  may be expressed by the equation
 
 S=Vt+ ½ at 2 ,
 
     where S is the travel distance (1.5 meters in this example) and V is the initial velocity (assumed to be zero in this example if hand  29  was stationary when smartphone  11  was dropped) and t is time. The symbol “a” is acceleration, which in this instance is the gravitational attraction of the earth or approximately 9.8 m/s 2 . If the above equation is solved for time, then, assuming smartphone  11  was dropped from the 1.5 meter height  33 , it will impact sidewalk  32  in about 0.55 seconds. 
     In one embodiment, smartphone  11  may include application software programming associated with controller  9  such that an activation signal is sent to deploy shock absorbers  16  when accelerometer senses an acceleration event exceeding a predetermined threshold. Thus, it may be determined, empirically that acceleration beyond a certain level may result in significant damage to housing  12  of smartphone  11  if a predetermined distance S is exceed or if accelerometer  13  detects acceleration for more than about one-half second in the embodiment described above. Whatever the predetermined threshold is, upon reaching that threshold, an activation signal is sent by controller  9  to triggering switch  23  to release detents  22  which permit spring loaded supports  18  to move cover structure  17  away from housing corners  19  of smartphone  11 . Either simultaneously therewith, or prior or subsequent thereto, spring loaded supports  25  slide bumper cushions  24  away from cover structure  17  such that shock absorbers  16  are in their fully deployed position as shown in  FIGS. 5, 6 and 8  prior to smartphone  11  striking surface  32 . Bumper cushions  24  will then absorb the impact of smartphone on surface  32  thereby protecting housing  12  and smartphone  11  from being damaged by the impact of smartphone  11  striking surface  32 . In addition to protecting against a drop of smartphone  11  by user  31 , shock absorbers  16  may also protect smartphone  11  in the event that user  31  throws smartphone  11  or if some other sudden movement of smartphone  11  for a predetermined time or distance is programmed in controller  9  to trigger deployment of shock absorbers  16 . 
     Referring to  FIG. 9 , smartphone  11  is shown floating on a liquid surface  34  which may be water. This water could be a lake, ocean, river or other naturally occurring liquid surface or it could be water in a bathtub, commode, sink or other container in a home or other environment. That is, in the event smartphone  11  comes into contact with surface  34 , bumper cushions  24 , which in one embodiment are made from buoyant material, cause smartphone  11  to float on liquid surface  34 . In  FIG. 9 , shock absorbers  16  are shown in a retracted position as may be the case where accelerometer  13  in smartphone  11  has not detected a triggering event such as a drop from a predetermined distance as described in  FIG. 8 . If, smartphone  11  was dropped or otherwise propelled onto water surface  34  with sufficient speed, or for a sufficient time, such that a triggering event occurred, then shock absorbers  16  would have been deployed as described above with respect to  FIGS. 5, 6 and 8  such that bumper cushions  24  and cover structure  17  would be extended away from corners  19  or housing  12 . In this embodiment, only one set of bumper cushions  24  would be in contact with water surface  34 . That is, in fully deployed position, bumper cushions  24  would separate away from cover structure  17  such that the  4  bumper cushions  24   b  (only 2 shown) are in contact with water surface  34  in the embodiment shown in  FIG. 9 . The upper bumper cushions, designated  24   u  in  FIG. 9  may or may not be in contact with water surface  34  depending upon the buoyancy of bumper cushions  24  and the weight of smartphone  11 . In the event that smartphone  11  was positioned on water surface  34  such that screen  14  was facing down, then bumper cushions  24   u  would be in contact with water surface  34  and bumper cushions  24   b  may or may not be in contact with water surface  34 . In some embodiments, the bumper cushions may extend sufficiently far enough away from the smartphone body on one or both sides that the body does not contact the water or other liquid, presuming the water or other liquid is relatively placid. 
     Referring to  FIG. 10 , a flow chart of a method for protecting a smartphone is shown. In step  35 , a portable electronic device  11  which may be a smartphone, tablet, media player, laptop computer or other device is held by a user. In step  36  the user inadvertently or otherwise drops or releases the portable electronic device  11 . It should be appreciated that these two operations may not form any part of the method for protecting the device, but may instead trigger the various operations of the method, as described below with respect to steps  37  et. seq. 
     In step  37 , an accelerometer  13  in the device senses movement and in step  38 , the distance and time of the movement are calculated and compared to a predetermined triggering event by a controller. If the time or distance as calculated in step  38  exceeds the predetermined triggering threshold, then in step  39 , an activation signal is sent by controller  9  to a triggering switch  23  or other instrument to deploy shock absorbers  16 . In step  41  shock absorbers are moved away from housing  12  and in step  42 , the bumper cushions slide away from the cover support. In one embodiment, steps  41  and  42  may occur simultaneously or, in another embodiment, step  42  occurs prior or subsequent to step  41 . 
     The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the described embodiments. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the described embodiments. Thus, the foregoing descriptions of the specific embodiments described herein are presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the embodiments to the precise forms disclosed. It will be apparent to one of ordinary skill in the art that many modifications and variations are possible in view of the above teachings.
