Abstract: The present disclosure provides systems and methods for determining occupancy status of a space. The systems and methods can utilize one or more space sensors in combination with one or more boundary sensors. The space sensors can transmit passive signals corresponding to presence of movement in the space. The boundary sensors can transmit boundary signals corresponding to movement into or out of the space. In response to falling edges of a passive signal and a boundary signal occurring within a predetermined time period of one another, an indication that the space is not occupied can be provided. In some cases, the passive signals and the boundary signals can be communicated via a gateway utilizing a signal communication protocol.

Abstract: According to one aspect, a system for processing a document image is disclosed. In an exemplary embodiment, the system includes an edge-detection unit configured to identify an edge of a document from a document image. The system also includes a keystone-correction unit and a flattening unit. The keystone-correction unit is configured to correct keystone distortion in the document image. The flattening unit is configured to flatten content of the document in the document image.

Abstract: 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.

Abstract: An eraser is usable in a display system having a display surface. The eraser includes one or more optical detection elements for determining the coordinates of the eraser relative to the display surface.

Abstract: A device and method of connecting an interactive communication system to a processing device. The device is a cable system that includes first and second ends.

Abstract: 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.

Abstract: An electronic module includes a printed circuit board with a heat producing electrical component assembled in an insulating housing. The component is adjacent a thermally conducting heat sink with a thermally conductive material disposed therebetween. Integral with the heat sink is a thermally conductive runner, partially encased in the housing wall, connecting the heat sink to a thermally conductive port. The port is coupled to a base structure when the housing is attached to the base, forming a heat conduction path from the component to the base. This conductive path may also provide an electrical ground path from the printed circuit board to the base.
