Abstract

A mobile communications device mechanism detects spatial distances from objects positioned in adjacency to a visual display of a mobile communications device and selectively powers off the visual display when the visual display is positioned within a select distance from a select object and powers on the visual display when the visual display is positioned outside the select distance from the select object. The mobile communications device mechanism has at least one distance sensor which detects the relative distance of the select objects positioned in adjacency to the mobile communications device. Further aspects of the invention provide the mechanism as a cradle for the mobile communications device, the mechanism containing sensor circuitry which communicates with circuitry for controlling the powering on and off of the visual display, the cradle also having a support surface (e.g. kickstand) for displaying the visual display of the mobile communications device at an oblique angle relative to the support surface. The at least one distance sensor can detect the distance from a user’s face as spatially positioned relative to the visual display.

Description

MECHANISM FOR AUTOMATICALLY POWERING OFF/ON A VISUAL DISPLAY BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The present invention relates generally to means for automatically powering off and powering on the visual display of a mobile or electronic communications device when the device is positioned within a certain distance from a user's face. A preferred embodiment of the present invention more particularly relates to a cradle or cover apparatus operable to encase or cover a mobile or electronic communications device exemplified by a tablet computer for detecting spatial distancing from a user's face and communicating with the communications device for automatically powering off and powering on the communications device depending on spatial distance from the user's face so as to prevent the visual display of the electronic communications device from harming the user's vision.
SUMMARY OF THE INVENTION
Among the many objectives of the invention is the provision of a tablet cover or cradle appartus that operates to cover or cradle and protect a mobile communications device exemplified by a tablet type computer so as to primarily shield the communications device from damage. Users of such devices are often children who often use such devices for educational purposes. It is noted that children are prone to place or position the visual displays of such devices at a position that is considered by some to be too close to the user's face or eyes, potentially causing harm to the user's vision.
Thus there is a perceived need in the art for a mechanim to safeguard the user from any damage that might occur to the user's eyes or vision by automatically turning off the visual displays of such communications devices when placed within a certain proximity or critical distance relative to the user's face or eyes, and to automatically turn on the visual displays of such communications devices when displaced or repositioned to a position that is outside a certain proximity or critical distance relative to the user's face or eyes.
In certain embodiments, the basic invention may be said to essentially teach or disclose a cradle apparatus for (a) cradling a mobile communications device, (b) detecting spatial distances from objects positioned in adjacency to the mobile communications device as cradled by the cradle apparatus, and (c) and communicating with the mobile communications device for selectively powering off or powering on the visual display of the mobile communications device depending on its distance from a target object exemplified by a user's face or eyes.
The cradle apparatus according to the present invention essentially comprises a cradle assembly, at least one distance sensor, and sensor support circuitry for powering off or powering on the cradled device with visual display based on proximity of the at least one distance sensor relative to a target object. The cradle assembly S esesnt ally configured for receiving or cradling the mobile communications device and displaying the visual display of the mobile communications device as cradled. The at least one distance sensor is positioned in cooperative association with the cradle assembly for detecting the relative distance of select or target objects positioned in adjacency to the visual display of the mobile communications device as received or cradled by the cradle assembly.
The sensor support circuitry preferably communicates the at least one distance sensor with a circuit or switch for powering off or powering on circuit components housed by the cradle assembly for further powering off the visual display when the cradle assembly is positioned within a select distance from a select object exemplified by a user's face and powering on the visual display when the cradle assembly is positioned outside the select distance from the select object exemplified by a user's face.
Each distance sensor is preferably positioned so as to be substantially coplanar with an anterior surface of the visual display of the mobile communication device as received or cradled by the cradle assembly for enhancing the accuracy of the object-to-device distance measurement. In this regard, it is contemplated that the preferred select distance is a distance value of 10 to 12 inches, which select distance may be adjusted according to the user's needs or preferences.
The cradle assembly preferably comprises an anterior visual display frame portion and a posterior device support portion. The at least one distance sensor may be preferably and posteriorly positioned adjacent at least one sensor aperture formed in the anterior visual display frame portion for detecting the distance of objects anteriorly located relative to the anterior visual display frame portion via the at least one sensor aperture.
In a preferred embodiment, the cradle apparatus according to the present invention comprises at least two distance sensors for enhancing the accuracy of object-to-device distance measurement. A first distance sensor of the at least two distance sensors is preferably positioned adjacent a first sensor aperture formed in a first visual display frame portion of the anterior visual display frame portion and a second distance sensor of the at least two distance sensors is preferably positioned adjacent a second sensor aperture formed in a second visual display frame portion of the anterior visual display frame portion.
The first visual display frame portion may preferably be defined by a select longitudinal end frame portion and the second visual display frame portion may preferably be defined by a select lateral side frame portion extending orthogonally relative to the select longitudinal end frame portion. The at least two distance sensors are thus preferably positioned at longitudinal and latitudinal positions relative the visual display for further enhancing the accuracy of object-to-device distance measurement.
The cradle apparatus according to the present invention may be said to alternatively and basically operate to cradle a visual display, detect spatial distances from objects positioned in adjacency to a cradled visual display, and selectively power on and off the cradled visual display depending on the spatial distancing between the cradled visual display and the target object. The cradle apparatus may thus be said to esentially comprise a cradle assembly, at least one sensor, and certain sensor support circuitry. The cradle assembly is essentially configured for receiving or cradling and simultaneously displaying the visual display.
Each distance sensor is preferably positioned in cooperative association with the cradle assembly for detecting the relative distance of select objects positioned in adjacency to the cradled visual display. The sensor support circuitry communicates each distance sensor with a circuit or switch for powering off the cradled visual display when the cradle assembly is positioned within a select distance from a select object and powering on the cradled visual display when the cradle assembly is positioned outside the select distance from the select object.
The present invention further contemplates certain means for eliminating the cradle apparatus and outfitting an electronic or mobile communications device directly with sensors for detecting spatial distance from a user's face which sensors may operate directly with the computing circuitry and hardware of the outfitted mobile communications device to automatically power off and power on the outfitted device depending on its spatial distance relative to the user's face for enhancing safe use of the oufitted device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings with more specificity, the present invention preferably provides various iterations of a cradle apparatus as generally depicted and respectively referenced at 10, 40, and 50. The cradle apparatuses 10, 40, and 50 according to the present invention basically cradle and protect a mobile or electronic communications device as depicted and referenced at 11 when outfitted thereupon.
For purposes of illustrative and descriptive ease, the mobile or electronic communications device 11 usable in combination with the cradle apparatuses 10, 40, and 50 according to the present invention may by typified or exemplified by a tablet computer apparatus having a visual display as at 12. The present invention contemplates further applicability to other similar mobile or electronic communications devices having visual displays, such as smart phones, laptops, and relatively less mobile visual displays such as desktop monitors and the like.
As prefaced above, the cradle apparatuses 10, 40, and 50 according to the present invention further operate to detect spatial distance of the cradle apparatuses 10, 40, and 50 with cradled device 11 or cradled visual display 12 from objects positioned in adjacency to the cradle apparatuses 10, 40, and 50. The spatial distance from the cradle apparatuses 10, 40, and 50 to the target object (e.g. a user's face as at 13) may then be detected and an object-to-device distance measurement operates to power on or power off the visual display 12 of the mobile communications device 11 as cradled or received by the cradle apparatuses 10, 40, and 50.
In this regard, the primary application contemplated by the cradle apparatuses 10, 40, and is to prevent any harmful effects that may otherwise occur when a visual display 12 is placed too close to a user's face 13 or eyes. The object-to-device distance measurement is the basis for powering off or powering on circuit components housed within the cradle apparatuses 10, 40, and 50 for further powering off or powering on the visual display 12 depending on the relative position of the cradle apparatuses 10, 40, and 50 and cradled visual display 12 relative to the user's face 13 as generally and comparatively depicted in Figure Nos. 6-8.
Referencing Figure No. 6, the reader will there consider a critical distance 100 from the first preferred embodiment or cradle apparatus 10 relative to the user's face 13. When the user's face 13 is moved or positioned within the critical or select distance 100 relative to plane 101 of the visual display 12 as cradled by the cradle apparatus 10, the visual display 12 of the mobile communications device 11 is powered off for disenabling the user to view content upon the visual display 12 as generally depicted in Figure No. 7.
When the user's face 13 is moved outside the critical or select distance 100 relative to the plane 101 of the visual display 12 as cradled by the cradle apparatus 10, the visual display 12 of the mobile communications device 11 is powered on for enabling the user to view content (as at 102) displayed thereupon. While it is contemplated that the preferred critical distance be on the order of 10 -12 inches, it is further contemplated that the critical distance 100 may be adjusted according to the needs or preferences of the user.
The cradle apparatus 10 according to the present invention preferably comprises a cradle housing or assembly 14 and sensor support circuitry housed within the cradle housing or assembly 14 for providing the above-noted functionality. The cradle assembly 14 is preferably configured for receiving and cradling the mobile communications device 11 and for readily displaying the visual display 12 of the mobile communications device 11. The cradle assembly 14 preferably comprises an an anterior visual display frame portion as at 15 and a posterior device-support portion as at 16.
The anterior visual display frame portion 15 preferably comprises at least one, but preferably two sensor apertures as at 17 for allowing distance sensor(s) 18 positioned in posterior adjacency to the sensor apertures 17 to detect object-to-device distance(s). In other words, at least one distance sensor 18 is preferably posteriorly positioned adjacent at least one sensor aperture 17 formed in the anterior visual display frame portion 15 for detecting distance of objects anteriorly located relative to the anterior visual display frame portion 15 via the sensor aperture(s) or slots 17.
It will be understood from a consideration of the illustrative support material submitted in support of these specifications that the cradle apparatus 10 according to the present invention preferably comprises at least two distance sensors 18 within the operating circuitry. A first distance sensor 18 of the at least two distance sensors 18 is preferably positioned adjacent a first sensor aperture 17 fonnd in a first visual display frame portion 19 of the anterior visual display frame portion 15 and a second distance sensor 18 of the at least two distance sensors 18 is preferably positioned adjacent a second sensor aperture 17 formed in a second visual display frame portion 20 of the anterior visual display frame portion 15. Highly accurate object-to-device distance measurement data may thereby be collected via triangulation principles in view of the fixed distance between the spaced sensors 18 that are preferably positioned so as to be substantially coplanar with the anterior surface of the visual display 12 as at plane 101.
Referencing Figure No. 1, the reader will there consider that the first visual display frame portion 19 may preferably be defined by a select longitudinal end frame portion of the two opposite, upper and lower longitudinal ends 21 of the cradle assembly 14. Further, the second visual display frame portion 20 may preferably be defined by a select lateral side frame portion of the two laterally opposed lateral side frame portions 22. The lateral side frame portions 22 generally extend orthogonally relative to the longitudinal end frame portions 21 such that the at least two distance sensors 18 are preferably positioned at longitudinal and latitudinal positions relative the visual display 12 for enhancing the accuracy of object-to-device distance measurement data obtained from the distance sensors 18 for selectively powering off or powering on the visual display 12 of the mobile communications device 11.
Referencing Figure No. 10, the reader will there consider the two spaced distance sensors 18 respectively positioned at the first visual display frame portion 19 as preferably defined by a select longitudinal end frame portion of the two opposite, upper and lower longitudinal ends 21 and at the second visual display frame portion 20 as preferably defined by a select lateral side frame portion of the two laterally opposed lateral side frame portions 22. Comparatively referencing Figure Nos. 9 and 10 the reader will further consider the sensor apertures 17 visibly located at the anterior side of the anterior visual display frame portion 15 as depicted in Figure No, 9. The distance sensors 18 are postioned in posterior adjacency to these slots or apertures 17 as comparatively depicted in Figure No. 10.
Further referencing Figure No. 9, the reader will there consider circuit components housed within or at the posterior device-support portion 16, including a main circuit board as at 23, a battery as at 24, an electromagnet as at 25, and a permanent magnet as at 26. These components are preferably covered by a circuit compartment cover as at 27. Figure No. 11 further depicts a sensor strip communication pathway as at 28 leading from the sensor strip 29 (outfitted with distance sensors 18 located at the ends thereof) to the main circuit board 23. It is contemplated that electromagnetizing the electromagnet 25 provides a simple and effective means to selectively and controllably power off and power on the visual display 12. In this regard, it is contemplated that magnet placement within the cradle assembly 14 may be device-specific for enabling the functionality.
The cradle assembly 14 may further preferably comprise a series of device-cooperative apertures, slots or formations as at 30. In this regard, it is well known in the art that communications devices provide certain peripheral input and output features so that users thereof may more effectively operate the devices. The device-cooperative apertures, slots or formations 30 are formed in the material construction of the cradle assembly 14 for enabling the user to utilize the device features via the cradle assembly 14.
