Abstract

A device for adjusting position of a display screen, the device (400) comprising: a front support (480) for holding the display screen (210); motor means (750, 760, 770) for adjusting the inclination of the front support (480); characterized in that it further comprises: a pair of horizontal infrared (IR) sensors (221, 222) configured to be positioned in parallel to a horizontal axis of the display screen (210); a pair of vertical infrared (IR) sensors (231, 232) configured to be positioned in parallel to a vertical axis of the display screen (210); and a controller (710) configured to measure the intensity of a signal received from a remote control unit (240) by the IR sensors (221, 222, 231, 232), and control the motor means (750, 760, 770) depending on the signal intensity measured by the IR sensors (221, 222, 231, 232).

Claims

1. A device for adjusting position of a display screen, the device (400) comprising:

a front support (480) for holding the display screen (210);

motor means (750, 760, 770) for adjusting the inclination of the front support (480);

characterized in that it further comprises;

a pair of horizontal infrared (IR) sensors (221, 222) configured to be positioned in parallel to a horizontal axis of the display screen (210);

a pair of vertical infrared (IR) sensors (231, 232) configured to be positioned in parallel to a vertical axis of the display screen (210); and

a controller (710) configured to measure the intensity of a signal received from a remote control unit (240) by the IR sensors (221, 222, 231, 232), and control the motor means (750, 760, 770) depending on the signal intensity measured by the IR sensors (221, 222, 231, 232).

2. The device according to claim 1, further comprising:

a mount (410) for mounting the device (400) to an external structure;

a set of foldable supporting arms (431, 432, 441, 442) between the mount (410) and the front support (480); and

a telescopic screw (450) driven by a motor drive (750) and mounted between the supporting arms for adjusting the distance between the mount (410) and the front support (480).

3. The device according to claim 2, further comprising:

a pivotal mount (470) positioned at the end of the telescopic screw (450) for a rotating mechanism (460) to which the front support (480) is attached;

wherein the pivotal mount (470) allows a rotational movement of the front support (480) about a vertical axis while the rotational mechanism (460) allows an inclination movement of the front support (480) set about a horizontal axis by means of motor drives (760, 770);

4. The device according to claim 1, wherein the horizontal IR sensors (221, 222) are configured to be positioned on the left and on the right side of the display screen respectively and the vertical IR sensors are configured to be positioned on the top and on the bottom side of the display screen respectively.

5. The device according to claim 1, wherein the extraction of the telescopic screw (450) is adjusted depending on the calculated swiveling angle.

6. A method for adjusting position of a display screen (210) mounted on a motorized support (480), characterized in that it comprises:

attaching to the display screen (210) a pair of horizontal infrared (IR) sensors (221, 222) in parallel to a horizontal axis of the display screen (210);

attaching to the display screen (210) a pair of vertical infrared (IR) sensors (231, 232) in parallel to a vertical axis of the display screen (210); and

measuring the intensity of a signal received from a remote control unit (240) by the IR sensors (221, 222, 231, 232), and controlling motor means (750, 760, 770) of the motorized support (480) depending on the signal intensity measured by the IR sensors (221, 222, 231, 232).
