摘要： 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.

摘要： The present invention is a whiteboard method and system (100) having automated projection calibration that does not require user interaction. The method and system are accomplished by placing sensors (302) beneath a target surface and projecting a projected pattern to discover a geometric correspondence between the target surface and the projecting device. Optical sensors (32) are preferably employed to sense the presence of the projected pattern on the whiteboard. The input data is used with a mapping function or translation matrix for converting whiteboard coordinates to screen coordinates, which are then used for mapping the coordinates to a cursor position. When the geometry of the whiteboard surface is known, and the locations of the optical sensors within this geometry are known, the information about which projector pixels illuminate which sensor can be used to calibrate the projecting device with respect to the whiteboard.

摘要： 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.

摘要： 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.

摘要： The present disclosure provides systems and methods for in-line thermal flattening and enameling of steel sheets. The systems and methods include an in-line thermal flattening of a feed stock steel sheet and a subsequent enamel coating of the steel sheet. The resulting enamel coated steel sheet has improved flatness compared with other coated steel sheets that are enamel coated but do not undergo the in-line thermal flattening. The systems and methods allow the use of less expensive source materials without sacrificing quality in the finished enameled product.

摘要： 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.
