BACKGROUND

[0002] Use of electronic devices, such as smartphones and tablets, has become ubiquitous and many people find their use of such electronic devices is compulsive to the extent that productivity or focus on other tasks is diminished. In addition, there are increasingly issues with addiction to use of the electronic devices themselves, internet overuse problems or internet addiction disorders enabled by the electronic devices, and addictions or compulsions for services accessed through electronic devices, such as social media and gambling.

[0003] Therefore, there exists a need to enable users of electronic devices to control their use, and to enable others to control access to electronic devices, for example parents controlling use by children.

BRIEF SUMMARY OF THE DISCLOSURE

[0004] In accordance with the present disclosure there is provided an apparatus for controlling use of an electronic device having a screen, the apparatus comprising a cover; a clamp for attaching the apparatus to the electronic device such that the cover is positioned over at least a portion of the screen; a lock arranged to lock the clamp such that the apparatus is locked to the electronic device; and a controller configured to control the lock.

[0005] When the apparatus is attached to the electronic device the cover is positioned over a portion of the screen, preventing use of the electronic device. The apparatus can therefore be used to prevent use of the electronic device for the time that the apparatus is attached to the electronic device.

[0006] In preferred examples the apparatus further comprises a user input device for receiving a user input, and the controller may be configured to receive the user input and control the lock based on the user input.

[0007] In some examples, the user input device may be configured to receive a user input indicating a time condition, and wherein controller is configured to lock the clamp for the time condition. The time condition may be a specified period of time that the apparatus should be locked for (e.g. 2 hours), or it may a particular time that the apparatus should be locked until (e.g. 14:00).

[0008] In some examples, the user input device may be configured to receive a further user input indicating that the lock should be released. In these examples the controller is configured to release the lock in response to the further user input. For example, the controller may be configured to receive the further user input from an authorised user identified via a passcode or fingerprint recognition.

[0009] In various examples, the user input device may comprise one or more of: a button; a dial; a switch; a graphical user interface, for example a touchscreen; a fingerprint sensor; and/or a wireless communications unit for receiving a user input via wireless communication with an external device. Therefore, the user input device may be a user input device of the apparatus (e.g. a button, dial, switch, etc...), or it may be a wireless communications device for receiving a user input from an external device, for example a further electronic device such as a smartphone.

[0010] In preferred examples, the apparatus may further comprise a mechanical override configured to release the lock to remove the apparatus from the electronic device. In some examples, the mechanical override may be configured such that operation of the mechanical override renders the apparatus unusable. That is, after the mechanical override is used to remove the apparatus from the electronic device the apparatus cannot be used again.

[0011] In particular, the mechanical override may comprise a sacrificial component configured to break on operation of the mechanical override. In other examples, the mechanical override may comprise a movable element that is moveable by a user. Moving the movable element may cause a component of the lock to move to a non-functional position to release the lock.

[0012] The apparatus may comprise a housing, and the clamp may comprise an extendible arm that extends from the housing. The extendible arm may comprise a gripping member at an end of the extendible arm configured to grip an edge of the electronic device, in particular a corner of the electronic device. The gripping member may grip a part of an edge of the electronic device, an entire edge of the electronic device, or a corner of the electronic device.

[0013] The lock may be configured to lock the position of the extendible arm relative to the housing.

[0014] The apparatus may include a first extendible arm and a second extendible arm. In these examples, the first and second extendible arms extend from the housing, and each of the first extendible arm and the second extendible arm comprises a gripping member at an end of the extendible arm configured to grip an edge of the electronic device, in particular a corner of the electronic device.

[0015] The first extendible arm preferably extends in a direction opposite to the second extendible arm. For example, the gripping members of the first and second extendible arms may be configured to grip opposing edges of the electronic device, in particular opposing corners of the electronic device.

[0016] In some examples, the or each gripping member comprises a pocket configured to receive an edge of the electronic device, in particular a corner of the electronic device. In preferred examples, the or each pocket comprises an inclined surface to accommodate different thickness electronic devices. In some examples, the or each pocket includes a deformable insert, such as an elastomeric insert.

[0017] The or each extendible arm may be spring loaded to an extended position. In this example, when the lock is released the extendible arms move to the extended position to release the electronic device.

[0018] In some examples, the cover may be configured to prevent a user viewing the portion of the screen covered by the cover. In particular, the cover may be opaque or translucent. Additionally or alternatively, the cover may be configured to prevent a user from touching the portion of the screen covered by the cover. In this example, if the screen is a touchscreen then the cover prevents a user from inputting commands. The cover is preferably configured to cover a substantial portion of the screen of the electronic device, for example all of the screen of the electronic device.

[0019] In some examples, the apparatus further comprises a display configured to display a status of the apparatus, for example a locked status and/or time information. The display may comprise a user input device, in particular a touchscreen.

[0020] The apparatus may further comprise a blocking member arranged to cover a port, button, switch, or other feature of the electronic device when the apparatus is attached to the electronic device.

[0021] The lock may comprise an actuator controllable by the controller, and a locking member arranged to engage the clamp to lock the clamp. The actuator may be configured to move the locking member into a locked position. In examples, the actuator may also be configured to move the locking member into an unlocked position, or permit the locking member to be moved into an unlocked position by a user.

[0022] In examples, the actuator may comprise a motor and the lock may further comprise a cam that is arranged to be rotated by the motor. The cam may be arranged to move the locking member into the locked position. In examples, the cam may also be configured to move the locking member into an unlocked position, or permit the locking member to be moved into an unlocked position by a user.

[0023] In some examples, the clamp may comprise an extendible arm arranged to grip an edge of the electronic device, and the lock may be configured such that the locking member is arranged to engage the extendible arm in the locked position to lock the position of the extendible arm.

[0024] In various examples, the apparatus may be configured to be attached to a smartphone, and/or a tablet computer, and/or a laptop, and/or a gaming device. The apparatus may be configured for electronic devices having a particular range of sizes, or may be configured to a particular electronic device.

[0025] In accordance with the present disclosure there is also provided a controller for an apparatus for controlling use of an electronic device, the apparatus comprising a cover, a clamp for attaching the apparatus to the electronic device such that the cover is positioned over at least a portion of the screen, a lock arranged to lock the clamp, and a user input device, wherein the controller is configured to control the lock according to a user input received via the user input device.

[0026] Preferably, the user input device is configured to receive a user input indicating a user-specified condition for unlocking the lock, and the controller may be configured to lock the clamp until the user-specified condition is satisfied. In various examples, the user-specified condition may be one or more of: a period of time, a specified time, and/or a further user input, for example authentication of an authorised user.

[0027] In accordance with the present disclosure there is also provided an electronic device configured to control the apparatus described above. The electronic device may comprise a user input device and a wireless communications unit configured to communicate with the controller of the apparatus. The electronic device may be configured to control the lock of the apparatus according to a user input received via the user input device of the electronic device.

[0028] It will be understood that any data processing, can be performed by a device having one or more processors and a memory including instructions to cause the one or more processors to perform the data processing, such as to process the scan data to generate the control data. The memory is typically a non-transient computer-readable storage medium.

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiments of the invention are further described hereinafter with reference to the accompanying drawings, in which: FIG. 1 shows apparatus that is attached to an electronic device, in particular a smartphone; FIG. 2 shows the apparatus on different size electronic devices; FIGS 3A and 3b illustrate a gripping member of the apparatus of FIGS. 1 and 2; FIGS. 4A to 40 illustrate a first example locking mechanism of the apparatus; FIGS 5A to 50 illustrate a second example locking mechanism of the apparatus; FIGS. 6A to 60 illustrate a third example locking mechanism of the apparatus; FIGS. 7A to 7D illustrate a fourth example locking mechanism of the apparatus; FIGS. 8A and 8B illustrate a fifth example locking mechanism of the apparatus; FIGS. 9A and 9B show a further example apparatus on an electronic device, in particular a smartphone; FIG. 10 illustrates communication between the apparatus and a further device; FIG. 11 schematically illustrates the apparatus; and FIG. 12 illustrates a method of using the apparatus. 15 DETAILED DESCRIPTION [0030] FIG. 1 shows apparatus 1 for controlling use of an electronic device, in particular a smartphone 2. The apparatus 1 is attached to the smartphone 2 and covers at least a portion of the screen 3 to block the view of the screen 3 and/or prevent a user from touching the screen 3 to use the smartphone 2. The apparatus 1 includes a clamp 4 for attaching to the smartphone 2, and a lock for locking the clamp 4 to lock the apparatus 1 to the smartphone 2. The apparatus 1 includes a controller for controlling the lock.

[0031] When the apparatus 1 is attached to the electronic device the apparatus 1 prevents the electronic device 1 from being used.

[0032] In some examples, the lock may be operated based on a timer to render the smartphone 2 unusable for a specified amount of time. For example, a user may provide a user input to lock the apparatus 1 onto the smartphone 2 for a period of several hours.

[0033] In other examples, the lock may be operated based on the time of day by using the controller to set a release time, for example 14:00. In this way, the apparatus 1 can be used to prevent use of the electronic device until a specified time of the day.

[0034] In some examples, an authorised user may be able to unlock the apparatus 1 before expiration of the specified amount of time, or before the specified time or day. For example, the apparatus 1 may be unlocked by entering a passcode or by using fingerprint recognition.

[0035] In other examples, a user may be able to unlock the apparatus 1 by entering a passcode or by using fingerprint recognition on the apparatus 1. Therefore, a user can lock the apparatus 1 to the smartphone 2 until they decide to unlock the apparatus 1. This may be useful if the apparatus 1 is being used to prevent use of someone else's smartphone 2, for example if a parent wanted to prevent their child using their smartphone 2.

[0036] In some examples, the apparatus 1 is in communication with a remote device, for example a further electronic device such as a smartphone. In this way, the lock of the apparatus 1 can be controlled from the remote electronic device.

[0037] The apparatus 1 may be used by a person who is concerned about their smartphone use, or who knows that they cannot or should not use their smartphone for a period of time, for example while driving, during an examination, or during the night. In other uses, the apparatus 1 may be used by a first user to prevent a second user from using their smartphone 2, for example a parent may use the apparatus 1 to render their child's smartphone unusable for a particular period of time, for example while completing homework or eating a meal.

[0038] Typically, a smartphone 2 has a screen 3, in particular a touchscreen, for displaying a graphical user interface that the user can interact with to operate the smartphone 2. A smartphone 2 is typically cuboid, having a major front face 5 with the screen 3, an opposite major face (not shown) that is the back of the smartphone 2, and a minor top face 6, a minor bottom face 7, and minor side faces 8, 9. Edges and corners of the smartphone 2 are typically curved. Often, one or more buttons, switches, or other user input devices are provided, for example a 'Home' button 10 on the front face, below the screen 3, and one or more volume and/or power buttons 11 on the side faces 8, 9. In addition, a typical smartphone will include one or more ports 12 for attaching power cables and/or headphones. Such ports are typically arranged on the top and/or bottom faces 6, 7 of the smartphone 2. A smartphone 2 may be provided with a protective case that envelops the back face, side faces 8, 9, and the top and bottom faces 6, 7 and leaves the screen 3 visible and accessible. The thickness of a smartphone 2 (i.e. distance between the front face 5 and the rear face) is typically between about 5mm and 20mm, most usually about 7mm to 10mm.

[0039] As illustrated, when the apparatus 1 is attached to the smartphone 2 a substantial portion of the screen 3 is covered by a cover 12 of the apparatus 1. The covered parts of the screen 3 are therefore not visible to a user, and if the screen 3 is a touchscreen the apparatus 1 may prevent the touchscreen being used by preventing user inputs to the part of the touchscreen that is covered. In some examples, the cover 12 is transparent or translucent so that a user can see the screen 3 but cannot touch it to control the smartphone 2. Therefore, the cover 12 of the apparatus 1 prevents the smartphone 2 from being used while the apparatus 1 is attached to the smartphone 2.

[0040] As shown in FIG. 1 and described in detail hereinafter, the apparatus 1 clamps onto the smartphone 2 by two arms 13, 14 that extend from a hub 15 of the apparatus 1. The arms 13, 14 grip opposing corners of the smartphone 2 to clamp the apparatus 1 over the screen 3. The hub 15 includes a lock for locking the arms 13, 14 in place. The cover 12 is also attached to the hub 15.

[0041] The apparatus 1 includes a controller for controlling a lock that locks the arms 13, 14. The controller may be housed in the hub 15. In this way, the controller controls whether the arms 13, 14 are unlocked and the apparatus 1 can be removed from the smartphone 2, or whether the arms 13, 14 are locked and the apparatus 1 is locked onto the smartphone 2.

[0042] As shown in FIG. 2, the arms 13, 14 are extendible so that the apparatus 1 can be used on different size smartphones 2, or other electronic devices such as tablet computers or gaming devices. On both smartphones 2 shown in FIG. 2, the cover 12 covers a substantial part of the screen 3 of the smartphone 2. In other examples, the apparatus 1 may be sized so as to useable on specific electronic devices or types of electronic device, for example for smartphones, for tablet computers, or for gaming devices.

[0043] The apparatus 1 shown in FIGS. 1 and 2 attaches to the smartphone 2 (or other electronic device) by the extendible arms 13, 14. The extendible arms 13, 14 each include a gripping member 16 at the end of the extendible arm 13, 14 that grips an edge or corner of the smartphone 2. The extendible arms 13, 14 can slide into and out of a housing 17 of the apparatus 1 to allow the gripping members 16 to be positioned over the sides or corners of the smartphone 2. The extendible arms 13,14 also allow the apparatus 1 to be used on different size electronic devices, for example different size smartphones, or on smartphones and tablet computers.

[0044] In alternative examples, the arms 13, 14 may grip an edge of the smartphone 2, for example an edge at any of the top face 6, bottom face 7, or side faces 8, 9. In some examples, the arms 13, 14 may grip the entirety of a face of the smartphone 2, for example the entire top face 6. In other examples, each arm 13, 14 may grip an entire edge of the smartphone 2, including both corners.

[0045] In some examples, the apparatus 1 includes one fixed arm and one extendible arm. The apparatus 1 can be attached to the smartphone by positioning the fixed arm over an edge of the smartphone 2 and then using the extendible arm to attach the apparatus 1 to the smartphone 2.

[0046] In some examples, the apparatus 1 may also include a blocking member that extends to block a port or button or other feature of the smartphone 2. For example, the apparatus 1 may include a blocking member that is arranged to extend over the port 12, the home button 10, or the side buttons 11 of the smartphone.

[0047] FIGS. 3A and 3B illustrate the gripping member 16 of an extendible arm 13, 14. FIG. 3A is a cross-section through plane 19 as illustrated in FIG. 38. As shown in FIG. 3A, the gripping member 16 comprises a pocket 20 that receives the corner 21 of the smartphone 2. The pocket 20 hooks around to the back face 18 of the smartphone 2 to attach the apparatus 1 to the smartphone 2. The pocket 20 preferably has a tapering surface 21 to accommodate smartphones having different thicknesses, and so that the pocket 20 grips the corner of the smartphone 2. Preferably, the tapering surface 21 comprises a deformable insert 22, for example an elastomeric material, to soften the grip on the smartphone 2 and to increase the grip.

[0048] As shown in FIG. 3B the pocket 20 is preferably shaped to match the shape of the corner 21 of the smartphone 2 so prevent the extendible arm 13, 14 being rotated to release it from the smartphone 2. In particular, the pocket 20 preferably has a triangular cross-section in the plane of the smartphone 2 to match the corner 21 of the smartphone 2.

[0049] Referring again to FIGS. 1 and 2, the apparatus 1 includes a cover 12 and a hub 15 that are positioned approximately in the middle of the screen 3 of the smartphone 2. The cover 12 is preferably rectangular and has an aspect ratio that approximately matches that of a smartphone 2. In particular, the aspect ratio (height/width) of the cover 12 is preferably between 1.5 and 2.5, preferably about 2. In preferred examples, for use on a smartphone 2 the cover 12 preferably has a height of between about 10cm and a width of about 5 cm, and for a tablet a height of about 20cm and a width of about 15cm.

[0050] The cover 12 is sized to cover a substantial portion of the screen 3, but the proportion of the screen 3 that is covered will vary for different size smartphones 2 and other electronic devices. The first and second extendible arms 13, 14 extend diagonally from the hub 15 to engage opposing corners of the smartphone 2 to attach the apparatus 1 to the smartphone 2.

[0051] It will be appreciated that if the aspect ratio of the apparatus 1 does not match the aspect ratio of the smartphone 2 then the cover 12 would be skewed with respect to the smartphone 2. However, within the small amount of variation in aspect ratio that exists between smartphones and other electronic devices, the cover 12 would still cover a substantial portion of the screen of the smartphone 2 and so the apparatus 1 would function as intended.

[0052] The housing 17 of the apparatus 1 includes slots for receiving the first and second extendible arms 13, 14 in a slidable manner. In this way, the apparatus 1 can be attached to different sized smartphones 2 and other electronic devices by extending the extendible arms 13, 14 to the appropriate length. As described further hereinafter, springs may be provided to spring-load the extendible arms 13, 14 to an extended or retracted position, preferably an extended position. A lock is provided to lock the extendible arms 13, 14 in place, and a controller controls the lock.

[0053] In some examples, the lock includes a mechanical override that can be used to unlock the apparatus 1 in an emergency. In some examples, use of the mechanical override renders the apparatus 1 unusable.

[0054] FIGS. 4A to 4C illustrate a first example of a lock 23 for locking the position of extendible arms 13, 14. As shown, a first extendible arm 13 slides between a first housing part 24 and a second housing part 25 in a linear direction of the first extendible arm 13. A compression spring 26 is provided between an end of the first extendible arm 13 and the housing 17 to urge the first extendible arm 13 into an extended position. The second extendible arm 14 is arranged in the same manner as the first extendible arm 13, but in an opposite orientation.

[0055] An inner surface 27 of each extendible arm 13, 14 comprises a series of slots 28. In particular, as shown, the inner surface 27 of each extendible arm 13, 14 has a plurality of semi-circular or hemi-spherical slots 28 formed in a row extending in a longitudinal direction of the extendible arm 13, 14. The inner surfaces 27 of the first and second extendible arms 13, 14 are arranged facing each other.

[0056] A locking mechanism 29 is disposed between the first and second extendible arms 13, 14, in particular between the two inner surfaces 27 with the slots 28. The locking mechanism 29 has an actuator, in particular a motor 30, a cam 31, a sliding member 32, and two locking balls 33. The controller (not shown in FIG. 4A) is configured to control the motor 30, and the cam 31 is attached to the motor 30 so that the motor 30 rotates the cam 31. The cam 31 is arranged to push the sliding member 32 in a direction parallel to the extendible arms 13, 14 when it is rotated. The sliding member 32 has a cam-engaging face 35 that the cam 31 pushes as it rotates. The sliding member 32 also has a wedge portion 34 that is arranged to push the locking balls 33 outwards as the cam 31 pushes the sliding member 32 in the longitudinal direction. As illustrated in FIG. 4B, movement of the sliding member 32 causes the locking balls 33 to be pushed outwards and into the slots 28 in the extendible arms 13, 14. In the position shown in FIG. 4B the extendible arms 13, 14 are locked and unable to be moved longitudinally.

[0057] To release the locking balls 33 the motor 30 can rotate the cam 31 back to the starting position, and the sliding member 32 can move back to release the locking balls 33 from the slots 28.

[0058] FIG. 4C illustrates a mechanical override for removing the apparatus 1 of FIGS. 4A and 4B from the smartphone 2 without the controller unlocking the locking mechanism 29 in the usual manner. In this example, the sliding member 32 has a protrusion 36 that extends into a slot (not shown) formed in the housing (not shown) so that a user can access the protrusion 36 with their finger or with an instrument, such as a pen nib. As shown in FIG. 4C, sliding the sliding member 32 in the longitudinal direction past the locking balls 33 permits the locking balls 33 to move out of the hemi-spherical slots 28, allowing the extendible arms 13, 14 to move so that the apparatus 1 can then be removed from the smartphone. Once the sliding member 32 is moved to the position shown in FIG. 4C the springs 26 push the extendible arms 13, 14 to their extended positions and in so doing push the locking balls 33 in behind the wedge portion 34.

[0059] In the example illustrated in FIG. 4C the sliding member 32 does not return to its previous position. Instead, once the sliding member 32 is moved up to the position illustrated in FIG. 4C, i.e. once the wedge portion 34 is past the locking balls 33, the locking balls 33 move behind the wedge portion 34 and prevent the sliding member 32 from moving back to its initial position. This breaks the locking mechanism 29 so that the mechanical override can only be used once, after which the locking mechanism 29 is broken and the apparatus 1 cannot be used again after being removed from the electronic device.

[0060] In an alternative example the sliding member 32 does return to its initial position after being moved up to release the locking balls 33. For example, the sliding member 32 may have sloped faces arranged opposite the wedge portion 34 that urge the locking balls 33 outwards as the sliding member 32 is returned to its initial position. A spring may be arranged to urge the sliding member 32 back to its initial position. In this example, the manual override does not break the apparatus 1, and it can be used again.

[0061] FIGS. 5A to 5C illustrate a further example of a lock 23 for locking the position of extendible arms 13, 14. Similarly to the example of FIGS. 4A and 4B, a first extendible arm 13 slides between a first housing part 24 and a second housing part 25 in a linear direction of the first extendible arm 13. A compression spring 26 is provided between an end of the first extendible arm 13 and the housing 17 to urge the first extendible arm 13 into an extended position. The second extendible arm 14 is arranged in the same manner as the first extendible arm 13, but in an opposite orientation.

[0062] An inner surface 27 of each extendible arm 13, 14 comprises a series of slots 28. In particular, as shown, the inner surface 27 of each extendible arm 13, 14 has a plurality of semi-circular or hemi-spherical slots 28 formed in a row extending in a longitudinal direction of the extendible arm 13, 14. The inner surfaces 27 of the first and second extendible arms 13, 14 are arranged facing each other.

[0063] A locking mechanism 29 is disposed between the first and second extendible arms 13, 14, in particular between the two inner surfaces 27 with the slots 28. The locking mechanism 29 has an actuator, in particular a motor 30, a rotary cam 31, and two locking balls 33. The controller (not shown) is configured to control the motor 30, and the rotary cam 31 is attached to the motor 30 so that the motor 30 rotates the rotary cam 31. The rotary cam 31 is has a circumferential cam surface 37 that pushes the locking balls 33 outwards and into the hemispherical slots 28 as the rotary cam 31 rotates, as illustrated in FIG. 5B. In the position shown in FIG. 5B the extendible arms 13, 14 are locked and unable to be moved longitudinally.

[0064] To unlock the extendible arms 13, 14 the motor 30 can rotate the rotary cam 31 back to the initial position, allowing the locking balls 33 to leave the hemispherical slots 28 and release the extendible arms 13, 14.

[0065] FIG. 5C illustrates a mechanical override for removing the apparatus 1 of FIGS. 5A and 5B from the smartphone without the controller unlocking the lock 23 in the usual manner. In this example, as illustrated, a slidable wall 38 is arranged on one side of the rotary cam 31 and has supporting protrusions 39 that, in the usual position illustrated in FIGS. 5A and 5B, hold the locking balls 33 in position between the rotary cam 31 and the slots 28. However, for the mechanical override the user can slide the slidable wall 38 and supporting protrusions 39 away from the cam 31, allowing the locking balls 33 to fall out of position and release the extendible arms 13, 14. One or more springs 40 may be provided to urge the slidable wall 38 against the rotary cam 31 in normal use. The user can reach the slidable wall 38 through an opening (not shown) in the housing 17, for example with a finger or with an instrument such as a needle or pen nib.

[0066] In one example, shown in FIG. 5C, the locking balls 33 fall into a recess 41 and do not return to their operational position. In this example, the mechanical override can only be used once, after which the lock 23 is broken because the locking balls 33 cannot return to position to be pushed into and out of the slots 28. This renders the apparatus 1 unusable.

[0067] In another example, the locking balls 33 move back into an operational position when the slidable wall 38 returns to the position shown in FIGS. 5A and 5B. In this example, the lock 23, mechanical override, and apparatus 1 can be used again.

[0068] FIGS. 6A to 60 illustrate a further example of a lock 23 for locking the position of extendible arms 13, 14. Similar to the previous examples, a first extendible arm 13 slides between a first housing part 24 and a second housing part 25 in a linear direction of the first extendible arm 13. A compression spring 26 is provided between an end of the first extendible arm 13 and the housing 17 to urge the first extendible arm 13 into an extended position. The second extendible arm 14 is arranged in the same manner as the first extendible arm 13, but in an opposite orientation.

[0069] An inner surface 27 of each extendible arm 13, 14 comprises a series of slots 28. In particular, as shown, the inner surface 27 of each extendible arm 13, 14 has a plurality of semi-circular or hemi-spherical slots 28 formed in a row extending in a longitudinal direction of the extendible arm 13, 14. The inner surfaces 27 of the first and second extendible arms 13, 14 are arranged facing each other.

[0070] A locking mechanism 29 is disposed between the first and second extendible arms 13, 14, in particular between the two inner surfaces 27 with the slots 28.

In the position shown in FIG. 7B the extendible arms 13, 14 are locked and unable to be moved longitudinally.

[0076] To unlock the extendible arms 13, 14 the motor 30 can rotate the cam 48 back to the initial position shown in FIG. 7A, allowing the locking arms 13, 14 to leave the slots 28 and release the extendible arms 13, 14.

[0077] FIG. 7D illustrates three examples of the locking arms 49, which each have an area of weakness 50 that provides a mechanical override for removing the apparatus 1 from the smartphone without the controller unlocking the lock 23 in the usual manner. In this example, the housing 17 of the apparatus 1 includes openings (not shown) through which the user can press a needle or pen nib to apply pressure to the weakened areas 50 of the locking arms 49 to break them, releasing the extendible arms 13, 14 and also breaking the lock 23 to prevent it and the apparatus 1 from being reused. In this example, the locking arms 49 are sacrificial components.

[0078] FIGS. 8A and 8B illustrate a further example of a lock 23 for locking the position of extendible arms 13, 14. Similarly to the previous examples, a first extendible arm 13 slides between a first housing part (not shown) and a second housing part (not shown) in a linear direction of the first extendible arm 13. A compression spring 26 is provided between an end of the first extendible arm 13 and the housing (not shown) to urge the first extendible arm 13 into an extended position. The second extendible arm 14 is arranged in the same manner as the first extendible arm 13, but in an opposite orientation.

[0079] An inner surface 27 of each extendible arm 13, 14 comprises a series of slots 28. In particular, as shown, the inner surface 27 of each extendible arm 13, 14 has a plurality of toothed slots 28 formed in a row extending in a longitudinal direction of the extendible arm 13, 14. The inner surfaces 27 of the first and second extendible arms 13, 14 are arranged facing each other.

[0080] A locking mechanism 29 is disposed between the first and second extendible arms 13, 14, in particular between the two inner surfaces 27 with the slots 28. The locking mechanism 29 has an actuator, in particular a motor 30, a cam 51 attached to the motor 30, a pinion gear 52 that is arranged to engage the slots 28 in both of the extendible arms 13, 14, and a pivotally mounted locking arm 53 shaped to engage the pinion gear 52. The pinion gear 52 may have an additional pinion gear 54 mounted to it that the locking arm 53 engages, as illustrated, or the locking arm 53 may engage the pinion gear 52 itself. The controller (not shown) is configured to control the motor 30 to rotate the cam 51, which pushes the locking arm 53 to rotate and engage the pinion gear 53, 54, as illustrated. When the locking arm 53 engages the pinion gear 53, 54 the extendible arms 13, 14 are locked and unable to be moved longitudinally.

[0081] To unlock the extendible arms 13, 14 the motor 30 can rotate the cam 51 back to the initial position, allowing the locking arm 53 to disengage the pinion gear 53, 54, releasing the extendible arms 13, 14.

[0082] In this example, as shown in FIG. 8B, the locking arm 53 includes a weakened area 55 that can be broken to provide a mechanical override for removing the apparatus 1 from the smartphone without the controller unlocking the lock 23 in the usual manner. The housing (17, not shown) of the apparatus 1 includes an opening (not shown) through which the user can press an instrument, such as a needle or a pen nib to apply pressure to the weakened area 55 of the locking arm 53 to break it, releasing the extendible arms 13, 14 and also breaking the lock 23 to prevent it and the apparatus 1 from being reused. In this example, the locking arm 53 is a sacrificial component.

[0083] Alternatively, the locking arm 53 may include a hinged portion 55 and the user can use an instrument, such as a needle or pen nib, to bend the locking arm 53 to disengage the locking arm 53 from the pinion gear 52, 54, allowing the extendible arms 13, 14 to be moved. The hinged portion 55 may be integrally moulded into the locking arm 53 and be biased to urge the locking arm 53 against the pinion gear 52, 54. In this example the lock 23 and apparatus 1 are reusable.

[0084] FIGS. 9A and 9B illustrate an example apparatus 1 comprising a display 56. The apparatus 1 includes a housing 17 comprising a hub 15, and extendible arms 13, 14 and a lock as previously described. The apparatus 1 also includes a controller for controlling the lock.

[0085] In examples where the apparatus 1 includes a timer, the screen 56 may show a time that is remaining until the apparatus 1 is unlocked and can be removed from the electronic device 2. The screen 56 may also be used by a user to select a time for locking the apparatus 1 before it is locked. In some examples, the apparatus 1 may include one or more buttons, switches, dials, or other user input devices for selecting a time period for locking the apparatus 1, and for activating the lock. The screen 56 may display the selected time period as the user inputs the time. In other examples, the screen 56 may comprise a user input device, for example a touchscreen.

[0086] In some examples, the apparatus 1, in particular the controller, locks the apparatus 1 for a time period specified by the user, for example 2 hours. In other examples, the controller has a time module that knows the current time (i.e. in hours and minutes), and the user input indicates a time that the apparatus 1 should be locked and unlocked, for example a user input may instruct the controller to lock the apparatus 1 until 14:00, or from 12:00 to 14:00.

[0087] The screen 56 may display a time remaining until the apparatus 1 is unlocked, for example in hours and minutes. As illustrated in FIGS. 9A and 9B, the screen may include a circular bar 57 indicating the time remaining until the apparatus 1 is unlocked. The bar 59 may reduce in length (arc length, in the illustrated example) proportionately to the time remaining until the apparatus 1 is unlocked.

[0088] In a preferred example the display 56 is a touchscreen display that shows one or more graphical user objects for a user to input a condition for locking the apparatus 1, for example a time period. For example, the display 56 may show plus and minus icons for selecting a time period. The display 56 may also display a 'start icon that the user selects to lock the apparatus 1 and start the timer.

[0089] Once the input time period has elapsed, or once the input time has been reached, the controller releases the lock and the apparatus 1 can be removed from the smartphone 2.

[0090] In some examples, the display 56 may comprise a fingerprint sensor. The controller may be configured to lock the apparatus 1 based on a user input (e.g. via the touchscreen 56 or another user input device) for a specified period of time (as described above), or indefinitely until a further user input is received to unlock the apparatus 1. The further user input may be a passcode or a fingerprint of an authorised user. For example, a parent may lock the apparatus 1 on their child's smartphone 2 for a specified time, or indefinitely, and/or until the parent's fingerprint is input to the fingerprint sensor to unlock the apparatus 1.
