For example, a hinge mechanism as described herein may be used to couple a housing of a device to a lid or couple an additional display to a housing or other structure that may or may not include a display.

Further aspects of the disclosed arrangements are described below in greater detail with reference to the figures. For purposes of simplicity and clarity of illustration, elements shown in the figures are not necessarily drawn to scale. Further, where considered appropriate, reference numbers are repeated among the figures to indicate corresponding, analogous, or like features.

<FIG> are perspective cutaway views of a device <NUM> with a non-claimed example hinge mechanism. In the examples of <FIG>, the hinge mechanism is a spine hinge. Referring to <FIG> collectively, a device <NUM> has a portion <NUM> and a portion <NUM>. Each of portions <NUM> and <NUM>, for example, may be a portion of the body of device <NUM>. Portion <NUM> has a surface <NUM> and a surface <NUM>. Portion <NUM> has a surface <NUM> and a surface <NUM>. In the closed position, surface <NUM> is in contact with surface <NUM> forming an angle of <NUM> degrees or approximately <NUM> degrees.

In the example of <FIG>, portion <NUM> and portion <NUM> are coupled by a hinge mechanism that includes a hinge <NUM> and a spine <NUM>. Portion <NUM> is capable of rotating around portion <NUM> about an axis of rotation defined by hinge <NUM>. In the closed position, device <NUM> resembles a closed book with spine <NUM> covering hinge <NUM> similar to a spine of a book covering the binding of the book. Spine <NUM> has an edge <NUM> that is attached to an edge of portion <NUM>. In an embodiment, edge <NUM> is attached, e.g., fixedly attached, to surface <NUM>. Edge <NUM> may be attached using an adhesive, fasteners, a bonding process, or other suitable attachment mechanism or process.

In one or more embodiments, spine <NUM> is coupled to a spring <NUM> and a damper <NUM>. Spring <NUM> and damper <NUM> are located within a channel <NUM> that resides within portion <NUM>. Spring <NUM> and damper <NUM> are oriented parallel to the plane formed by surface <NUM> and perpendicular to edge <NUM> of spine <NUM> and to the edge of spine <NUM> that is opposite edge <NUM>. In particular embodiments, spring <NUM> is included in the hinge mechanism. Spring <NUM> provides the force necessary to automatically open device <NUM>. Damper <NUM> is capable of providing a dampening force that opposes the force exerted by spring <NUM>. In the example of <FIG>, damper <NUM> is implemented as a linear damper. In one or more embodiments, damper <NUM> has a twin tube structure. Further, damper <NUM> may be pneumatic or hydraulic.

Referring to the example of <FIG>, damper <NUM> has a damper base <NUM> and damper member <NUM>. Damper base <NUM> may be implemented as an outer tube that is attached to portion <NUM> within channel <NUM>. Damper base <NUM> has an end that is capable of receiving damper member <NUM>. Damper member <NUM> may be implemented as a piston, for example. Damper member <NUM> is moveable into and out of damper base <NUM>. An end of damper member <NUM> that remains outside of damper base <NUM> is attached to a fastener <NUM>. Fastener <NUM> is attached to spine <NUM>, e.g., the edge of spine <NUM> opposite edge <NUM>. Spring <NUM> is coupled to damper <NUM>. For example, a first end of spring <NUM> is attached to damper base <NUM>. A second end of spring <NUM> is coupled to damper member <NUM>. Accordingly, damper <NUM> is capable of controlling the rate at which spring <NUM> is able to open device <NUM>. For example, the rate at which device <NUM> opens is controlled by the dampening effect generated by damper <NUM> countering the force exerted by spring <NUM>.

When device <NUM> is in the closed position with surface <NUM> in contact with surface <NUM>, spring <NUM> is extended so as to exert sufficient force to open device <NUM>. Device <NUM>, for example, can include a latch (not shown) that maintains device <NUM> in the closed position. When the latch is released, device <NUM> opens due to the force exerted by spring <NUM>. In the closed position, spine <NUM> is largely external to portion <NUM>. A small portion of spine <NUM> is within a track formed within portion <NUM>, which is revealed in the cut-away view of <FIG>. In response to the latch being released, spring <NUM> pulls spine <NUM> down the track within portion <NUM> in the direction of arrow <NUM>. Spring <NUM> draws spine <NUM> deeper within the track. As spine <NUM> is drawn deeper within the track, the portion of spine <NUM> within the track maintains an orientation that is substantially parallel to surface <NUM>.

In the example of <FIG>, two damper/spring assemblies are shown. Each damper/spring assembly is located in a dedicated channel. In another embodiment, a single damper/spring assembly may be used. In that case, channel <NUM> may be located at a position that is approximately midway between the two channels illustrated in <FIG>. In another embodiment, three or more damper/spring assemblies may be used. For example, in cases where three or more damper/spring assemblies are used, each such assembly may be located in a different channel and the channels may be spaced approximately equidistant from one another.

Referring to <FIG>, device <NUM> is shown in an open position with the spine hinge forming an angle less than <NUM> degrees. The spine hinge is retractable. Referring to <FIG>, device <NUM> is shown in an open position so that the spine hinge forms an angle greater than <NUM> degrees. In the example of <FIG>, device <NUM> is capable of opening to an angle of approximately <NUM> degrees as measured from surface <NUM> to surface <NUM>.

Example materials for implementing portions <NUM> and <NUM> include, but are not limited to, plastic, metal, ceramic, and other suitable materials. Example materials for implementing spine <NUM> include, but are not limited to plastic, metal sheeting, metal mesh, fabric, and other suitable materials. For example, spine <NUM> is flexible so as to bend as illustrated in <FIG> to support <NUM>-degree rotation. Still, spine <NUM> is also capable of maintaining a general shape or form (e.g., curvature) as illustrated in <FIG>.

<FIG> are side, partial cutaway views of device <NUM> of <FIG> with the example spine hinge. In the example of <FIG>, device <NUM> is in a closed position and is viewed from the side. Edge <NUM> of spine <NUM> is attached to portion <NUM> within a slot extending inside of portion <NUM>. Spine <NUM> is also within the track of portion <NUM>. In the example of <FIG>, a side covering <NUM> is added to each side of device <NUM> to close off the area between spine <NUM> and hinge <NUM>. In one or more embodiments, side covering <NUM> is implemented as a bellows. Side covering <NUM> is capable of expanding when device <NUM> is in the closed position as illustrated in <FIG>. When in an open position as illustrated in <FIG>, side covering(s) <NUM> is capable of collapsing, e.g., folding, between the respective ends of portions <NUM> and <NUM> beneath hinge <NUM>. Side cover <NUM> is capable of providing support for spine <NUM> so that spine <NUM> maintains a desired curvature at least while device <NUM> is in the closed position.

Spine <NUM> is capable of bridging between portion <NUM> and portion <NUM>. Spine <NUM> is positioned opposite hinge <NUM>, e.g., as a fulcrum. As device <NUM> opens from the closed position, spine <NUM> retracts into portion <NUM>. As device <NUM> closes from an open position, spine <NUM> withdraws from portion <NUM>.

In one or more embodiments, side covering <NUM> may be an outer covering. In that case, device <NUM> may have another internally sealed volume within side covering <NUM> and spine <NUM>. The internally sealed volume may be water tight and is capable of connecting the edges of portions <NUM> and <NUM>. Side covering <NUM> may be external. In one or more embodiments, side covering <NUM> provides further protection to the internally sealed volume. In particular embodiments, side covering <NUM> is capable providing an improved esthetic to device <NUM>. As an illustrative and non-limiting example, within side covering <NUM> and spine <NUM>, device <NUM> can have a water tight bellows or a flexible membrane connecting, e.g., attached to, end <NUM> of portion <NUM> and end <NUM> of portion <NUM>. The water tight region, for example, may allow electrical wires to pass between portion <NUM> and portion <NUM>.

<FIG> is a perspective cutaway view of device <NUM> including another non-claimed example of a spine hinge. <FIG> illustrates a cross-sectional side view of the example spine hinge of <FIG>. Referring to <FIG> collectively, the spine hinge is capable of providing <NUM> degrees or approximately <NUM> degrees of rotation. Further, a hinge (e.g., hinge <NUM>) is not included to facilitate the <NUM> degrees of rotation. The example of <FIG> includes an additional spine <NUM>. Spine <NUM> is attached in an opposing manner compared to spine <NUM>. For example, whereas spine <NUM> has edge <NUM> attached to portion <NUM>, spine <NUM> has an edge <NUM> attached to portion <NUM>.

As illustrated in <FIG>, edge <NUM> is attached to a surface of portion <NUM> located within a slot within portion <NUM>. Spine <NUM> is coupled to a spring/damper assembly <NUM> within a channel <NUM> of portion <NUM>. Spine <NUM> may be coupled to one or more spring/damper assemblies <NUM> as described with reference to spring <NUM> and damper <NUM> of <FIG>. It should be appreciated that the particular configuration of spring/damper assembly <NUM> and number of such assemblies may be implemented to match the spring/damper assembly and number of such assemblies in portion <NUM>. For example, as the cross-section of <FIG> illustrates, spring/damper assembly <NUM> may be aligned below the spring <NUM> and damper <NUM> assembly in portion <NUM>.

Accordingly, in the closed position, spine <NUM> is substantially extracted from portion <NUM>, while spine <NUM> is substantially retracted within portion <NUM>. In the <NUM>-degree open position illustrated in <FIG>, both spine <NUM> and spine <NUM> are substantially retracted. As device <NUM> is rotated beyond the <NUM>-degree open position of <FIG>, spine <NUM> is pulled from channel <NUM> so that spine <NUM> is substantially extracted from portion <NUM>, while spine <NUM> is substantially retracted within portion <NUM>.

In the examples of <FIG>, one end of the spines is fixedly attached to one of the portions of device <NUM>. In the examples shown, the spines are attached within slots in the portions. In particular embodiments, the spines can be fixedly attached to the outer surface of the appropriate portion. For example, spine <NUM> can be coupled to surface <NUM> of portion <NUM>, while spine <NUM> is attached to surface <NUM> of portion <NUM>. Spines <NUM> and/or <NUM> may be fixedly attached to one of portions <NUM> or <NUM> as the case may be using any of a variety of suitable attachment mechanisms. Further, spines <NUM> and/ or <NUM> may be fixedly attached to any of a variety of locations on portion <NUM> or <NUM>, as the case may be.

<FIG> is a perspective cutaway view of device <NUM> with another non-claimed example of a hinge mechanism. In the example of <FIG>, the hinge mechanism is a rolling contact hinge. <FIG>, are cross-sectional side views of the device of <FIG>. Referring to <FIG> and <FIG> collectively, device <NUM> has a rolling contact hinge that includes linkages <NUM> and <NUM>. In particular embodiments, the ends of portions <NUM> and <NUM> are curved or rounded. For example, the ends of portions <NUM> and <NUM> may be hemi-cylindrical as opposed to other shapes such as rectangular as pictured in <FIG>. Linkage <NUM> includes pins <NUM> and <NUM>. Linkage <NUM> includes pins <NUM> and <NUM>. Pins <NUM> and <NUM> are engaged by portion <NUM>, e.g., holes or a circular shaped channel within portion <NUM>. Pins <NUM> and <NUM> are engaged by portion <NUM>. In the example of <FIG> and <FIG>, portion <NUM> is capable of rotating about an axis formed by pins <NUM> and <NUM>. Portion <NUM> is capable of rotating about a second axis of rotation formed by pins <NUM> and <NUM>.

The rolling contact hinge of <FIG> through <FIG> further includes a plurality of straps <NUM>, <NUM>, <NUM>, and <NUM>. An additional strap may be included adjacent to strap <NUM> on the opposite side of strap <NUM>, but is not pictured so as to avoid obscuring the view of other components. In the example shown, the number of straps is for purposes of illustration only. In one or more embodiments, the straps may be narrower in width thereby allowing more straps to be included. In one or more embodiments, fewer straps may be used. For example, two straps may be used. Straps <NUM>-<NUM> are interleaved and provide for motion control as described herein in greater detail in connection with <FIG>.

In one or more embodiments, straps <NUM>-<NUM> are implemented as a flexible material. In an example, straps <NUM>-<NUM> are implemented as a flexible film. Example materials from which straps <NUM>-<NUM> may be implemented include, but are not limited to, plastic, fabric, or other suitable materials.

As pictured, each strap is attached to a first surface of portion <NUM> and an opposing surface of portion <NUM>. In <FIG>, for example, device <NUM> is in an open position with an angle of approximately <NUM> degrees. As shown, strap <NUM> has a first end attached to surface <NUM> (bottom) of portion <NUM> and a second end attached to surface <NUM> (top) of portion <NUM>. Strap <NUM> has a first end attached to surface <NUM> (top) of portion <NUM> and a second end attached to surface <NUM> (bottom) of portion <NUM>. Strap <NUM> and strap <NUM> cross one another when viewed from the side of device <NUM>. Strap <NUM> is attached the same way that strap <NUM> is attached. Strap <NUM> is attached the same way that strap <NUM> is attached. Thus, straps <NUM>-<NUM> effectively alternate in the way in which each strap attaches to portion <NUM> and <NUM> of device <NUM>.

The terms "top" and "bottom," at least with reference to attachment of straps, are used in reference to the particular orientation and angle of rotation of device <NUM> shown in <FIG>. When device <NUM> is in a closed position, for example (as pictured in <FIG>), surface <NUM> is facing outward as is surface <NUM>, with surfaces <NUM> and <NUM> in contact with one another. Thus, the particular surface considered the "top" or "bottom" depends upon the angle of rotation of the hinge mechanism formed by portion <NUM> and portion <NUM>.

In the example of <FIG> through <FIG>, springs <NUM> and <NUM> are included. Springs <NUM> and <NUM> may be implemented as torsional coil springs that are capable of providing the force necessary for device <NUM> to open automatically. A damper <NUM> is included. Damper <NUM> may be implemented as a cylindrical damper. In the example shown, pin <NUM> extends through damper <NUM>. Damper <NUM> controls the rate at which device <NUM> opens from the force provided by springs <NUM> and <NUM>.

In particular embodiments, pin <NUM> is fixedly attached, or part of, linkage <NUM>. Pin <NUM> is fixedly attached, or part of, linkage <NUM>. For example, pin <NUM> may be integrated into linkage <NUM>. Pin <NUM> can be integrated into linkage <NUM>. As an illustrative and non-limiting example, pin <NUM> (<NUM>) and linkage <NUM> (<NUM>) can be a single, unified structure. Pin <NUM> is received by an aperture or hole in linkage <NUM>. For example, pin <NUM> may snap into position as received by linkage <NUM>. Further, pin <NUM> passes through spring <NUM> and damper <NUM>. Pin <NUM> is received by an aperture or hole in linkage <NUM>. For example, pin <NUM> may snap into position as received by linkage <NUM>. Further, pin <NUM> passes through spring <NUM>.

<FIG>, taken collectively, illustrate the action of the rolling contact hinge as device <NUM> is opened. As device <NUM> opens (e.g., or closes), one strap (or set of straps) unwinds, while the other strap (or set of straps) winds, thereby maintaining a substantially constant length relationship and ensuring synchronous movement. Because the two straps (or two sets of straps e.g., where straps <NUM> and <NUM> form one set and straps <NUM> and <NUM> form another set) do not change in length and lay flat on the hemi-cylindrical surfaces of portions <NUM> and <NUM>, the straps do not allow the hemi-cylindrical surfaces to slip relative to each other. The hemi-cylindrical surfaces of portions <NUM> and <NUM> are constrained to roll in the same way that two meshing gears are constrained. As such, straps <NUM>-<NUM> exhibit a gear-like behavior. The rigid link provided by linkages <NUM> and <NUM> prevents portions <NUM> and <NUM> from separating. Straps <NUM>-<NUM> also help to prevent portions <NUM> and <NUM> from separating.

<FIG> illustrate that straps <NUM>-<NUM> facilitate rolling contact between the end of portion <NUM> and the end of portion <NUM>. While the two ends of portions <NUM> and <NUM> roll about one another, neither end comes into direct contact with the other since the straps <NUM>-<NUM> are between the ends to facilitate smooth and synchronized rolling. Each of the ends <NUM> and <NUM> of portion <NUM> and portion <NUM>, respectively, that abut are rounded or curved to facilitate smooth rolling contact throughout the <NUM> degrees of rotation provided. Ends <NUM> and <NUM> may have the same curvature to facilitate a smooth rolling effect. As discussed, in one or more embodiments, end <NUM> of portion <NUM> and end <NUM> of portion <NUM> may be hemi-cylindrical. Accordingly, in the example of <FIG>, strap <NUM> is unwinding from portion <NUM>, while strap <NUM> is winding around portion <NUM>.

In one or more embodiments, linkages <NUM> and <NUM> are configured to allow electrical wires to pass through. For example, one or more wires carrying power and/or data signals may be routed through either one or both of linkages <NUM> and <NUM>. Thus, data signals and/or power signals are able to pass from electronics within portion <NUM> to electronics within portion <NUM>. In particular embodiments, one linkage is capable of carrying power signals, while the other linkage is capable of carrying data signals. In particular embodiments, one or both of linkages <NUM> and/or <NUM> are capable of carrying both data signals and power signals.

In one or more embodiments, straps <NUM>-<NUM> are configured to include wires carrying data signals and/or power signals. As an illustrative and non-limiting example, one or more or all of straps <NUM>-<NUM> may be implemented using flexible circuitry. In another illustrative and non-limiting example, straps <NUM>-<NUM> may be implemented using fabric or flexible plastic where one or more wires are attached (e.g., glued or bonded) to the fabric and/or flexible plastic.

<FIG> illustrates a perspective view of device <NUM> including another non-claimed example hinge mechanism. In the example of <FIG>, the hinge mechanism is a magnetic rolling contact hinge. Referring to <FIG>, portion <NUM> has a rounded end <NUM>. Portion <NUM> has a rounded end <NUM>. In the example of <FIG>, rounded ends <NUM> and <NUM> have the same curvature to facilitate a smooth rolling effect. For example, rounded ends <NUM> and <NUM> each may be hemi-cylindrical.

Portion <NUM> includes a magnet array <NUM> and a magnet array <NUM>. Portion <NUM> includes a magnet array <NUM> and a magnet array <NUM>. Each magnet array may be formed of a plurality of magnets arranged adjacent to one another as pictured. In one or more embodiments, magnet arrays <NUM>-<NUM> are arranged in a helix or partial helix formation. For example, magnet array <NUM> and magnet array <NUM> each is arranged as a right-handed helix. Magnet array <NUM> and <NUM> each is arranged as a left-handed helix. Magnetic arrays <NUM>-<NUM> may be fixedly attached to ends <NUM> and <NUM> using an adhesive or other suitable attachment mechanism.

Rounded end <NUM> and rounded end <NUM> are able to roll about one another while maintaining synchronization using magnet arrays <NUM>-<NUM>. For example, magnet array <NUM> and magnet array <NUM> may be aligned so that opposite poles align across from one another as the rolling motion occurs. Similarly, magnet array <NUM> and magnet array <NUM> may be aligned so that opposite poles align across from one another as the rolling motion occurs.

In the example of <FIG>, magnetic arrays <NUM>-<NUM> are provided for synchronizing rotation of portions <NUM> and <NUM>. It should be appreciated that further structure such as linkages (with pins), dampers, and springs as described with reference to <FIG> and <FIG> may also be included. As an illustrative and non-limiting example, magnetic arrays <NUM>-<NUM> may be used in place of the straps in the examples of <FIG> and <FIG> to implement a magnetic rolling contact hinge for device <NUM>. In one or more other embodiments, magnet arrays <NUM>-<NUM> may also provide damping so that a separate or discrete damper is not required.

<FIG> is a cross-sectional side view of the device of <FIG>. <FIG> illustrates an example implementation of the magnet arrays of <FIG>. In the example of <FIG>, portions <NUM> and <NUM> are shown in cross-section. As rounded end <NUM> and rounded end <NUM> roll on one another, magnetic array <NUM> aligns with magnet array <NUM> so that north poles of magnet array <NUM> are aligned with south poles of magnet array <NUM>. Similarly, south poles of magnet array <NUM> are aligned with north poles of magnet array <NUM>.

<FIG> is a perspective view of portion <NUM> and magnet arrays <NUM> and <NUM>. <FIG> illustrates the helix shape formed by magnet arrays <NUM> and <NUM> within portion <NUM>.

<FIG> illustrates rolling action facilitated by the magnetic rolling contact hinge. In the example of <FIG>, magnet array <NUM> and magnet array <NUM>, each being at least partially helical and being opposite in terms of handedness, facilitate synchronization of portion <NUM> and portion <NUM> as rounded ends <NUM> and <NUM> roll about one another.

In the example embodiments illustrated in <FIG>, it should be appreciated that rounded ends <NUM> and <NUM> of portion <NUM> and portion <NUM>, respectively, are made using a magnetically permeable material. In one or more embodiments, rounded ends of portions <NUM> and <NUM> are made of a non-ferrous material. In one or more embodiments, rounded ends of portions <NUM> and <NUM> are made of other materials such as, for example, plastics, glass, aluminum, polychlorinated biphenyl (PCB), or other suitable materials.

In the examples described in connection with <FIG>, the magnets in each of the magnet arrays are arranged adjacent to one another. For example, the magnets in magnet array <NUM> abut one another. Further, the particular shape of each magnet array need not be a helix or partial helix. In one or more other embodiments, magnets of a magnet array may be spaced apart within approximately <NUM>-<NUM> degrees of rotation so long as magnets in magnet array <NUM> (<NUM>) are paired with magnets in magnet array <NUM> (<NUM>), e.g., with opposing poles, so that magnets on one side (e.g., in one portion) are looking for a paired magnet on the other side (e.g., in the other portion).

In one or more other embodiments, each of magnet arrays <NUM>-<NUM> may be implemented as a polymagnet as opposed to an array of discrete magnets. In particular embodiments, a strip corresponding to the surface of attachment of each of magnet arrays <NUM>-<NUM> on rounded edges <NUM> and <NUM> may be magnetized as a polymagnet to provide the synchronization described. As such, separate magnetic structures are not needed since portions or strips of rounded ends <NUM> and <NUM> are capable of being magnetized as polymagnets to perform the functionality described in connection with <FIG> to facilitate the rolling contact described.

<FIG> is a perspective cutaway view of device <NUM> including another non-claimed example hinge mechanism. In the example of <FIG>, the hinge mechanism is implemented as a film hinge. In the example of <FIG>, portion <NUM> is coupled to portion <NUM> by a film <NUM>. In one or more embodiments, film <NUM> is pleated. For example, film <NUM> may have one or more folds. The folds, or pleats, are parallel to an axis of rotation <NUM> about which portion <NUM> rotates. Linkage <NUM> has a pin <NUM> and a pin <NUM>. Linkage <NUM> has a pin <NUM> and pin <NUM>. Linkage <NUM> and <NUM> may be implemented substantially similar to linkages <NUM> and <NUM>, respectively, of <FIG> and <FIG>. In the example of <FIG>, however, pins <NUM> and <NUM> slide within slots <NUM> and <NUM>, respectively.

Pin <NUM> passes through spring <NUM>. In one or more embodiments, pin <NUM> passes through damper <NUM>. In particular embodiments, pin <NUM> passes at least partially through damper <NUM>. Damper <NUM> may be implemented as a cylindrical damper. Pin <NUM> passes through spring <NUM>. Springs <NUM> and <NUM> may be implemented as torsional coil springs. As pictured, pins <NUM>, spring <NUM>, damper <NUM>, spring <NUM>, and pin <NUM> are aligned along axis of rotation <NUM>. Portion <NUM> is capable of rotating around axis of rotation <NUM>. Portion <NUM> is capable of rotating around a second axis of rotation aligned with pins <NUM> and <NUM>.

Linkage <NUM> is coupled to pin <NUM>. In an embodiment, pin <NUM> is attached to linkage <NUM>. In another embodiment, linkage <NUM> is formed with pin <NUM> as an integrated part of linkage <NUM>, e.g., as a single, unified structure. Linkage <NUM> is coupled to pin <NUM>. Linkage <NUM> may be coupled to pin <NUM> as described in connection with linkage <NUM> and pin <NUM>. Pin <NUM> is inserted into a slot <NUM> positioned along a side of portion <NUM>. Pin <NUM> is inserted into a slot <NUM> positioned along a side of portion <NUM> opposing the side with slot <NUM>.

In the example of <FIG>, the film hinge is opened, e.g., powered, by springs <NUM> and/or <NUM>. Springs <NUM> and <NUM> are capable of providing the force used to automatically open device <NUM>. Damper <NUM> provides dampening and is capable of controlling the rate at which device <NUM> opens. In one or more embodiments, film <NUM> is folded into layers to allow approximately <NUM> degree or <NUM>-degree rotation. As illustrated, one side of each of linkages <NUM> and <NUM>, e.g., pins <NUM> and <NUM>, slide in slots <NUM> and <NUM>, respectively, while device <NUM> opens and/or closes. Pins <NUM> and <NUM>, for example, slide in slots <NUM> and <NUM> due to the changes in distance created by portion <NUM> rotating around an axis that is removed from the plane of the linkage, e.g., axis of rotation <NUM>.

<FIG> are cross-sectional side views of the device of <FIG> that, taken collectively, illustrate <NUM>-degree rotation using the film hinge. In <FIG>, device <NUM> is in a closed position. In the closed position, film <NUM> has a fold <NUM>. Fold <NUM> has an angle of approximately zero degrees.

In one or more embodiments, element <NUM> is a ribbon cable illustrating one example for coupling circuitry in portion <NUM> with circuitry in portion <NUM>.

In one or more other embodiments, element <NUM> is a torsional leaf spring. As a torsional leaf spring, element <NUM> is capable of providing force needed to open device <NUM>. In the example of <FIG>, other structures such as pins and dampers are not shown to more clearly illustrate element <NUM>. In particular embodiments, two or more of elements <NUM> may be included and pass through housing <NUM> where one or more of elements <NUM> are torsional leaf springs and one or more of elements <NUM> are ribbon cables. Thus, both a torsional leaf spring and a ribbon cable may pass through housing <NUM> to provide communication between circuitry in portions <NUM> and <NUM> and also to provide force that automatically opens device <NUM>.

In one or more embodiments, a torsional leaf spring as illustrated in <FIG> may be incorporated into device <NUM> in the example of <FIG> where spine(s) are used. The torsional leaf spring (or springs) may be used to provide further rotational force for automatically opening device <NUM>.

The example embodiments described herein can include a latch that keeps device <NUM> in the closed position until the latch is released. The latch may be implemented as any of a variety of different latch types. Example latch types include, but are not limited to, magnetic, electromagnetic, mechanical, magnetic/mechanical, and electromechanical. The particular type of latch included in device <NUM> is not intended to limit the example embodiments described herein.

In one or more embodiments, the latch is configured to release in response to successful user authentication. For example, device <NUM> may include a fingerprint sensor, voice/speaker recognition, eye/facial scanning, receive an input password or gesture via an externally accessible touch pad or touch sensitive surface, via near field communication (NFC) tag, or a handshake with another device such as a smart watch or another portable device or appliance.

An example of a magnetic latch may be implemented using printed magnets. A first magnet may be printed on surface <NUM> of portion <NUM> and a second magnet printed on surface <NUM> of portion <NUM>. The two magnets may be located and/or positioned so as to come in contact with one another when device <NUM> is in the closed position. The poles of each printed magnet may be aligned when device <NUM> is in the closed position so as to attract one another thereby keeping device <NUM> in the closed position. The attractive force of the latch, for example, is sufficient to overcome the forces provided for automatic opening of the hinge mechanism and device <NUM>.

One of the magnets may be printed on a surface or element that is configured to provide a small amount of movement. In response to movement of one of the printed magnets, e.g., when the latch is to open, the poles of the two printed magnets no longer align to provide attractive force and instead repel thereby releasing the latch. As an illustrative example, one of the magnets may be mechanically connected to a button or may be moved by a solenoid that is controlled by a manual control or a user authentication process (e.g., electronically).

The example embodiments described herein may include any of a variety of different types of dampers. In one or more embodiments, the dampers are passive mechanisms. Examples of passive dampers include hydraulic dampers (e.g., dampers that utilize oil) whether rotary or linear, and air dampers (e.g., linear). Other examples of passive dampers include miniature fly wheels, mechanical brakes, and patterned magnetic brakes.

In one or more embodiments, the dampers are active mechanisms. Examples of active mechanisms include magnetorheological fluid, solenoid clutch, and a motor and/ or generator. A magnetorheological fluid, also referred to as a ferrofluid, may be used so that application of a magnetic field to the fluid changes the properties of the fluid to either increase or decrease damping. For example, a ferrofluid may be included within the linkages described with reference to <FIG> and <FIG>. Application of the magnetic field can increase and/or decrease damping. Increasing damping a sufficient amount allows the mechanism to provide one or more position stops. In the examples of <FIG> and <FIG>, a controller (e.g., a processor capable of executing program code or other suitable control circuitry) may be included that is capable of adjusting a magnetic field applied to the ferrofluid within the linkages so as to dynamically control damping and/or provide one or more position stops.

In particular embodiments, the controller is capable of controlling operation of an active damper used with the hinge mechanisms described herein. By controlling the amount of damping provided by an active damper such as a magnetorheological fluid, a solenoid clutch, a motor, or a generator, the controller is able to electronically control and vary the amount of damping provided. Thus, the damper is capable of providing a variable amount of damping to vary the rate of opening of device <NUM> under electronic control of the controller. Further, the controller is capable of controlling whether the active damper implements position stops and/or changing the angle at which position stops are implemented.

In one or more embodiments, the damping may be controlled, e.g., electronically controlled, based upon the position of device <NUM>, the orientation of device <NUM>, and the size of the angle formed by portion <NUM> and portion <NUM>. In particular embodiments, position stops may be selectively implemented by the active damper under control of the controller based upon position of device <NUM>, the orientation of device <NUM>, and/or the size of the angle formed by portion <NUM> and <NUM>. It should be appreciated that a controller can coupled to one or more sensors within device <NUM> such as accelerometers, gyroscopes, and other suitable motion sensors in order to detect position, orientation, and angle as described herein.

In one or more embodiments, position stops may be incorporated into the hinge mechanisms. In particular embodiments, the position stop mechanisms are passive. Examples of passive position stop mechanisms include cam/rockers, mechanical brakes, patterned magnetic brakes, and flat surfaces on rounded ends (e.g., ends <NUM> and <NUM>) of each of portions <NUM> and <NUM>. The passive position stop mechanisms can be incorporated to provide one or more position stops in the rotational movement of the hinge mechanisms so that device <NUM> has resistance and stops the automatic rotation (or opening) at particular angles of rotation. In the case of the flat surfaces, the flat surface(s) can be located on the rounded ends <NUM> and <NUM> of portions <NUM> and <NUM> so that the flat surface of portion <NUM> contacts the flat surface of portion <NUM> through synchronized movement in example embodiments as described in connection with <FIG>, <FIG>, <FIG>, <FIG>.

In one or more embodiments, elements such as cam/rockers and motors and/or generators may be used to provide position stops. The cam/rockers and motors and/or generators are examples of active position stop mechanisms. As noted, active dampers can be electronically controlled to provide a variable amount of damping under control of a controller.

For example, an active damper that can be electronically controlled can be controlled to provide a position stop and behave as a position stop mechanism under control of a controller. In another aspect, the position stop mechanism is passive.

<FIG> illustrate an example of a cam/rocker position stop mechanism. In the example of <FIG>, a linkage <NUM> is illustrated. In one or more embodiments, linkage <NUM> may be used as the linkage in any of the examples described in connection with <FIG> to provide position stops for device <NUM>.

<FIG> is an overhead cutaway view of linkage <NUM>. In the example of <FIG>, a plurality of rockers (e.g., indentations) <NUM> are built into an outer surface of linkage <NUM>. Rockers <NUM> serve as position stops for device <NUM>. A spring <NUM> and a cam <NUM> are also built into linkage <NUM>. Spring <NUM> and cam <NUM>, for example, may be included in a channel or slot of portion <NUM> so that cam <NUM> is in contact with linkage <NUM> by virtue of force exerted by spring <NUM>. Spring <NUM> is capable of providing downward force (in reference to the position of linkage <NUM> illustrated in <FIG>) so that cam <NUM> contacts linkage <NUM> and is capable of settling into one of rockers <NUM>. As portion <NUM> rotates about axis of rotation <NUM>, cam <NUM> is capable of settling into one or more of rockers <NUM> in consequence of the force exerted by spring <NUM>.

In one or more embodiments, the cam rocker mechanism described in <FIG> is capable of stopping the automatic opening of device <NUM> as cam <NUM> engages the first of rockers <NUM>.

By the term "approximately" it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.

As defined herein, the terms "one embodiment," "an embodiment," "one or more embodiments," or similar language mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment described within this disclosure. Thus, appearances of the phrases "in one embodiment," "in an embodiment," "in one or more embodiments," and similar language throughout this disclosure may, but do not necessarily, all refer to the same embodiment. The terms "embodiment" and "arrangement" are used interchangeably within this disclosure.

As defined herein, the term "processor" means at least one hardware circuit configured to carry out instructions contained in program code. The hardware circuit may be an integrated circuit. Examples of a processor include, but are not limited to, a central processing unit (CPU), an array processor, a vector processor, a digital signal processor (DSP), a field-programmable gate array (FPGA), a programmable logic array (PLA), an application specific integrated circuit (ASIC), programmable logic circuitry, a graphics processing unit (GPU), and a controller.

The terms first, second, etc. may be used herein to describe various elements. These elements should not be limited by these terms, as these terms are only used to distinguish one element from another unless stated otherwise or the context clearly indicates otherwise.

In some alternative implementations, the operations noted in the blocks may occur out of the order noted in the figures. For example, two blocks shown in succession may be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. In other examples, blocks may be performed generally in increasing numeric order while in still other examples, one or more blocks may be performed in varying order.
