This application is a continuation application of a U.S. non-provisional application Ser. No. 11/028,790, filed Jan. 3, 2005, which claims priority to a U.S. provisional patent application Ser. No. 60/533,923, entitled SYSTEM FOR REMOTELY ADJUSTING THE VIEWING ANGLE OF A MONITOR, filed Jan. 2, 2004. Both applications are hereby incorporated by references.
1. Field of the Invention
This invention is directed to a support arm capable of adjusting the viewing angle of a monitor remotely and/or automatically to allow a viewer to watch the monitor more comfortably at the desired viewing angle.
2. General Background
Flat screen monitors such as computer monitors and plasma televisions (collectively referred to as “monitor(s)”) are becoming popular because they can be mounted onto a wall to save floor space and for their aesthetically pleasing appearance. In particular, monitors are generally mounted to a wall with a mechanical support arm then fixed in a desired orientation to maximize the viewing angle of the monitor. To later adjust the viewing angle of the monitor, however, a viewer generally tilts the monitor manually to a new viewing angle so that the viewer may more comfortably view the monitor from a different location. For instance, a monitor may be fixed to a wall in a family room to allow the family members or one viewer to view the monitor at the desired viewing angle. As the viewer moves from one area to another area, such as from the family room to the kitchen, the viewer may not be able to view the monitor. In addition, in situations where the monitor is mounted in a remote location or high above the floor, it may be inconvenient for the viewer to adjust the viewing angle of the monitor. As such, there is a need for adjusting the viewing angle of a monitor so that a viewer may view the monitor comfortably from a variety of locations.
This invention provides a support arm to couple a monitor to a surface such as a wall or ceiling to remotely or automatically adjust the viewing angle of the monitor. The support arm includes at least one motor along a pivot axis in the support arm. The motor may be activated by a processor based on the control signal provided by the remote control. The support arm may include a plurality of pivot axes with a motor in each of the pivot axis to adjust the viewing angle along at least one plane such as the vertical and/or horizontal plane. The support arm may be also provided with a tracking device that follows the movement of the viewer to adjust the viewing angle of the monitor corresponding to the movement of the viewer. The support arm may also receive periodic signal from the remote control to determine the location of the remote control. Based on the periodic signal, the processor may adjust the viewing angle of the monitor towards the location of the remote control.
Other systems, methods, features and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within the description, be within the scope of the invention, and be protected by the accompanying claims.
The invention can be better understood with reference to the following figures. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.
This invention is generally directed to remotely controlling the viewing angle of the monitor that is mounted onto a surface or in a remote area.
The viewing angle adjustment system 2 may also include a remote control 36 having a control button 38 capable of remotely controlling the viewing angle of the monitor 32 that is coupled to the support arm 10. In general, a viewing angle may be described as the position of the monitor that it is comfortable for a viewer(s) to watch the monitor. As such, the viewing angle may change from on viewer to another and also change as one or more viewers move around within the viewing area relative to the location of the monitor. The viewing angle may be also described as a line that is perpendicular to the plane of the monitor about its center point. In this regard, the remote control 36 may have a processor 35 that is capable of activating the motors along the pivot axes 16, 24, 26, and 34. The remote control 36 may be used to control the rotation of the motors along their respective pivot axes to adjust the viewing angle of the monitor 32. The control signal from the remote control 36 may be provided by a viewer or though other input data as discussed below. A receptor 50 may be provided on the monitor or on the support arm 10 to receive the control signal from the remote control 36.
Based on the input data from a viewer, the processor 35 provide a control signal to each of the motors that needs to rotate to orient the monitor 32 at a desired viewing angle. The processor 35 may calculate the rotation of each of the motors, if any, so that the monitor 32 may be moved from an initial viewing position to a new desired viewing position with minimal delay or through least amount of movements by the arms 12 and 14. Besides the remote control 35, the processor 35 may also be provided within the support arm 10 such as in the bracket 28, for example. If the processor 35 is located within the remote control 36, the input data from a viewer may be processed by the processor 35 to send a control signal to the receptor 50 to efficiently rotate each of the motors in the support arm 10 to orient the monitor 32 to the desired viewing angle. The receptor 50 may receive the control signal from the remote control 36 and forward the control signal to the motors within the support arm to adjust the viewing angle of the monitor accordingly. If the processor 35 is located on the support arm 10, then the remote control 36 may send the input data from the viewer to the receptor 50, which is then processed by the processor 35 to efficiently rotate the motors accordingly. This way, a viewer may adjust the viewing angle of the monitor remotely by using the control button 38 on the remote control 36. For instance, a viewer may activate the control button 38 either to the left position or to the right position to pivot the viewing angle of the monitor 32 to the clockwise or counter clockwise direction, respectively, when viewed from the top.
A memory 37 may be provided with the processor 35 to store the desired movement of the monitor 32 along the horizontal plan desired by the viewer. That is, the remote control 36 may be provided with a teach function 39 that allows the viewer to input the desired movement of the monitor 32 along the horizontal plan to the processor 35 which is then stored to the memory 37. For instance,
The desired first position and the second position may vary depending on the viewer but each viewer may teach the desired arc movement to the processor 35. This may involve activating one or more motors in the axes 16, 24, and 26. The desired movement of the monitor 32 may be provided so that the support arm 10 and the monitor 32 may avoid an impeding object that is near the monitor such as a book shelf, column, lamp, or an adjacent wall. Once the desired arc movement of the monitor is stored into the memory 37, the processor 35 may follow the desired arc movement when the viewer activates the control button to the right or left position. In addition, the teach function 39 may be also used to define certain boundaries so that the movement of the monitor is limited to a certain area. This may be done to prevent the monitor from running into adjacent walls, for example. Accordingly, a viewer may adjust the viewing angle of the monitor to the left along the X and Y plane by pressing on the control button 38 to the left which causes the monitor 32 to move to the left, and if the desired arc movement has been programmed into the memory 37, then the movement of the monitor 32 may follow the stored arc movement. Once the monitor is at the desired viewing angle along the X and Y plane, the viewer may depress the control button 38 to stop of the movement of the monitor 32.
Once the monitor 32 is adjusted for the desired viewing angle along the X and Y plane, the viewing angle of the monitor 32 may be also adjusted along the vertical plane or X and Z plane.
The number of pivot axes provided with the support arm 10 may vary. For instance,
The remote control 36 may be provided as a miniaturized transmitter that sends periodic signals to the receptor 50. The transmitter may be attached to a viewer such as on the viewer's collar or shirt so that the viewing angle of the monitor may follow the movement of the viewer. In addition, the transmitter may be attached to the head gear of the viewer or hat so that the viewing angle of the monitor may follow the rotation of the viewer's head. For instance, a surgeon may use an endoscope to visualize the internal organs of a patient during a surgery; a monitor coupled to the endoscope may follow the rotation of the surgeon's head so that the surgeon may conveniently view the monitor. The monitor may also have a variety of sensors to detect nearby objects so that the movement of the monitor may avoid the nearby objects. In such applications, the bracket 28 for the support arm 10 may be coupled to any apparatus or ceiling rather than a wall to support the monitor 32.
This invention may be used in a variety of applications. For instance,
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of this invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents.
