Abstract:
This invention provides an improved display system and method that is created by adjusting the properties of one or more displays to obtain coarse control over display behavior, by using sensors to optimize display parameters. The display is further improved by constructing a display map by selectively driving the display and sensing the optical image created. Furthermore, the sensors are used to ensure that the resulting optimized display meets target quality measurements over time, potentially taking into account ambient conditions. The system reports on its status, and is able to predict when the system will no longer meet a quality target. The system and method is able to optimize a display system and keep it optimized over time. Individual displays with the display system can have operating points that are matched to each other. Corrections to the input image signal to deliver improved display system performance can be minimized, and therefore, the unwanted artifacts of those changes can be minimized. If the displays drift over time, those operating points can be updated. If ambient conditions change, and new operating points are desired, the new operating points can be automatically selected. Operators of the display who require a minimum level of quality for the display system (e.g. a minimum intensity level) can be ensured that the display meets those requirements. And, they can be warned in advance as to when system maintenance can be necessary, when quality falls below targeted goals system and method provides for sending out methods of the quality of the system such an in an e-mail, perhaps in the form of graphs. Or, the system in method allows for prediction of when quality targets will not be met. Prediction is useful for a display system operator who needs to know when to perform maintenance, such as changing a light bulb (light source) in a projector.

Abstract:
The invention provides a system and method that reduces the precision of the manual alignment process. Users select correspondences between projectors or components of a projector, to form a common coordinate. Using models of the display system, and projectors, the common coordinate system can be mapped quickly to the entire display. The process avoids a need to measure screen points, and allows the user to move significantly fewer points. Alternatively, the invention allows introduction of machine-vision style algorithms into manual calibration techniques to improve performance. This overcomes the tediousness of prior systems by introducing models of the display into the manual alignment process, allowing selection of a small number of points on each projector, and avoiding selection of precisely measured screen points. The system conversely finds correspondences between projectors, allowing mapping of the projectors into a common coordinate system, and quick warping of the coordinate system to the screen.
Abstract:
A method and system for improving display quality by injecting a portion of computer code into an existing compositor, using the portion of computer code to apply a mapping function to a first digital image, and forming a second digital image based upon the first digital image as adapted by applying the applied mapping function in the compositor. The second digital image may then be displayed to a viewer via one or more displays where each display forms a part of the displayed digital image. The result may be used for creation of blended or stereoscopic images. The mapping function may be also adapted for modification of geometry or correction of a characteristic (such as color, intensity, etc.) of the display system where such characteristic may be sensed using a detector. The portion of code may be injected into a graphics driver controlling hardware composition for a displayed digital image.
Abstract:
A light-emitting-diode (LED) video cabinet having a native 16:9 aspect ratio is provided. One embodiment comprises a rectangular frame having a 16:9 aspect ratio; a video display portion mounted to the frame, the video display portion having width and height dimensions such that the video display portion natively displays video information in a 16:9 aspect ratio without a need for aspect-ratio conversion of a video input signal, the video display portion including at least four LED video modules; a video receiving card mounted to the frame, the video receiving card receiving the video input signal and transmitting the video information to the video display portion; and a power supply mounted to the frame, the power supply providing electrical power to the video receiving card and the video display portion. A plurality of such LED video cabinets can be seamlessly joined together to form a LED video display.
Abstract:
This invention provides a calibration system and method for multi-unit display systems without a need for switching the system input resolution/configuration of the display system while calibrating. This serves to avoid carrying out a re-synchronization step. As such, this system and method allows for increases speed and reduced likelihood of failure. This system and method also corrects the display system by providing an arrangement that employs a minimum of required changes so as to avoid any changes that can consequently affect the output image of the display system. Calibration of the system of display units occurs free of any changes to the input resolution and this resolution is maintained in a manner that resists change unless specifically required. Moreover, this system and method enables a resolution for the overall system that differs from the sum of the input resolutions of the discrete, individual display units in the collection.
Abstract:
A large scale LED display has a number of display panels each having a cable and spacer support structure for a number of LED modules. Adjacent display panels are connected together by a number of seam links that snap onto one cable of one of the display panels and one cable of the adjacent display panel. The cables may include a number of seam link engagement members spaced along the length of the cable and onto which the seam links snap wherein each of the seam link engagement members locates an LED module on the support structure. The LED modules include top and bottom housing sections that snap together, wherein one of the housing sections includes a seat for an electrical connector. The seat locates the connector and a printed circuit assembly within the LED module.
Abstract:
An anti-theft assembly for deterring theft of a ring is provided. The anti-theft assembly includes a base that can be used to support an electronic article surveillance marker; a product engagement member including a support member that supports the ring during use and a locking member that secures the support member to the base; and an attachment member for securing the ring to the support member. In one embodiment, the support member and the locking member are a single, unitary member. In another embodiment, the support member and the locking member are separate members. Once assembled, upon applying a twisting force to the ring the engagement member rotates within the opening so that the attachment member is not broken.
Abstract:
An anti-theft tag includes a body that carries an EAS sensor, a shrinkable sleeve disposed about the outside of the body, an adhesive material disposed on the body between the body and the sleeve, and a sleeve holder extending from the body. The sleeve holder is constructed and arranged to hold the sleeve on the body such that a portion of the sleeve and the body define an aperture configured to receive an elongate article, such as an arm from a pair of eyeglasses. In use, once the anti-theft tag is disposed on the article, an assembler shrinks the sleeve to secure the anti-theft tag to the arm. In such a configuration, the sleeve and adhesive material holds the body of the anti-theft tag against the arm, thereby limiting the ability for a thief to remove the anti-theft tag from the elongate article by twisting or rotating the anti-theft tag relative to the article.
Abstract:
An anti-theft tag deterring theft of a ring is provided. The anti-theft tag includes an elongated housing for accommodating an EAS marker, a product support member that locks into the housing and which supports the ring, and a flexible, tear resistant strap for securing the ring to the support member, the strap being disposed at least partially within the housing during use. In one embodiment, the support member includes an arcuate seat portion for supporting a circular shank portion of the ring, and a locking member that locks into a corresponding cavity in the housing. In use, the tear resistant strap extends over the ring shank, and the strap ends are received within the cavity of the housing to protect the strap from unauthorized removal by a consumer.
