20140198981 | DOCUMENT UNBENDING SYSTEMS AND METHODS - Embodiments of a processing systems and methods can unbend an image of facing pages of a bound book. An exemplary processing system can comprise an edge-detection unit, a keystone-correction unit, a flattening unit, and a conversion unit. After an image is received by the processing system, the image can be processed in turn by each unit. The edge-detection unit can identify edges of a document in the image. The keystone-correction unit can reduce or remove keystoning in the image, thereby correcting horizontal distortion of the document. The flattening unit can flatten or straighten text or objects in the image, thereby correcting vertical distortion of the document. The conversion unit can convert the image to a desired color profile. Accordingly, the processing system can process an original image into a more easily readable and digitally manipulable image. | 07-17-2014 |

20120162870 | CONVENIENTLY ASSEMBLABLE INTERACTIVE SYSTEMS - Interactive systems can include various components that are packaged together and easily assemblable. An interactive system can comprise a mount, a display device, a projector, an input device, and a processing device. The display device, the projector, the input device, and the processing device can together provide an electronic display system, while the mount can carry these other various components and assist in connecting them to one another. The mount and the other components of the interactive system can be conveniently packaged and sold as group for convenient installation by one or two persons. | 06-28-2012 |
20120162061 | ACTIVATION OBJECTS FOR INTERACTIVE SYSTEMS - An interactive system can include a display device, a control panel, a projector, a processing device, and an input device. The input device can detect indicia of its posture relative to the control panel or a display surface of the display device, so that the interactive system can recognize interactions between the input device and these components. Interactions between the input device and the display surface can be captured, analyzed by the processing device, and then represented in an image projected onto the display surface. The control panel can comprise a plurality of non-projected, tactile activation objects, each of which can correspond to an activity or function of the interactive system, such as, for example, powering on the projector. When the interactive system detects an interaction between the input device and an activation object, the activity corresponding to the selected activation object can be performed. | 06-28-2012 |
20120069054 | ELECTRONIC DISPLAY SYSTEMS HAVING MOBILE COMPONENTS - Electronic display systems include mobile units for remotely modifying a displayed image. An electronic display system can include a display surface, a processing device, a mobile unit, and an input device. The display surface can receive and display an image rendered by the processing device. The display image on the display surface can be modified through interaction of the input device and the mobile unit. The input device can sense its position relative to the mobile unit and can transmit data relating to its position to the processing device. The processing device can interpret the position data as operations on the displayed image. Accordingly, the processing device can modify the displayed image on the display surface based on interactions between the input device and the mobile unit. | 03-22-2012 |
20120064503 | DISPLAY MOUNTING SYSTEMS - Mounting systems can releasably secure display devices to preexisting surfaces for convenient installation and removal without external tools. A mounting system can comprise lower magnetic assemblies, upper magnetic assemblies, and a mounting sheet. The lower magnetic assemblies can be secured to a rear surface of a display device, for releasably attaching the display device to a preexisting surface. A bottom portion of the mounting sheet can be secured to the rear surface of the display device, while a top portion of the mounting sheet can remain loose from the rear surface. The upper magnetic assemblies can be provided along the loose top portion of the mounting sheet, for releasably attaching the display device to the preexisting surface. The upper magnetic assemblies can retain their connection to the preexisting surface as the display device is pulled away from the preexisting surface, until a threshold condition is met. | 03-15-2012 |
20100275132 | INTERACTIVE COMMUNICATION SYSTEMS - The present invention includes interactive communication systems that incorporate several beneficial embodiments including an interactive tray system, an electronic presentation messaging system, an interactive podium, and a key drive system. The interactive tray system enables a single, transferable interactive unit to be fastened to a communication medium, turning into a fully interactive medium. The electronic presentation messaging system enables the e-mailing of presentations and notes to and from components of the interactive communication system. The interactive podium increases conventional podium mobility, enabling both the presenter, and podium, to move and be moved about the room without attention to wired connections. The key drive system replaces the conventional Y-connector of the key drive technology by effectively integrating the key drive in the device, thus only having one connector, and eliminating the need to change connectors from the key drive, to the USB connector, upon software driver loading. | 10-28-2010 |
20090309854 | INPUT DEVICES WITH MULTIPLE OPERATING MODES - An input device for interacting with a display surface of an electronic display system. The input device can comprise a body, a nib, a sensing system, a cap, and a mode-indicating system. The body can provide structural support for the input device. The nib, which is in communication with the body, can be used to directly interact with the display surface. The sensing system can sense indicia of a posture of the input device with respect to the display surface to facilitate operation of the input device. The cap is securable over the nib, and can be incorporated into the mode-indicating system. When the cap is secured over the nib, the input device can operate in a first operating mode, and when the cap is removed, the input device can operate in a second operating mode. | 12-17-2009 |
