Abstract: An audio/video (A/V) hub includes a state-detection circuit coupled to at least one pin in a high-definition multimedia-interface input connector, which can electrically couple to an entertainment device. When electrically coupled to the entertainment device, the state-detection circuit establishes a ground loop between the electronic device and the entertainment device. A control circuit in the A/V hub detects whether there is electrical coupling with the entertainment device using the state-detection circuit. When the electrical coupling is detected, the control circuit provides a set of first control commands associated with different types of entertainment devices until, in response, content activity is detected via the input connector.

Abstract: An interactive projector is provided with a projection section adapted to project an image on a screen surface, a detection section, and a correction section. The detection section detects presence or absence of contact of the pointing element with the screen surface based in a relationship between a difference between a Z-coordinate value of the pointing element and a Z-coordinate value of the screen surface, and a difference threshold value set in advance. The correction section corrects at least one of the Z-coordinate value of the screen surface, the Z-coordinate value of the pointing element, and the difference threshold value based on a history of the Z-coordinate value of the pointing element.

Abstract: With respect to an image of at least one color component included among a plurality of color components, an image processing apparatus decides a position shift correction amount for reducing a shift between a position indicated by data and a position in the image in a projected state, and applies position shift correction to the image based on the position shift correction amount that has been decided. The image processing apparatus calculates an edge intensity to be used in edge emphasis processing for the image based on the position shift correction amount, and executes the edge emphasis processing with respect to the image after the position shift correction based on the calculated edge intensity.

Abstract: A computer system that provides situational awareness and feedback during a surgical procedure is described. During operation, the computer system generates stereoscopic images at a first 3-dimensional (3D) location in an individual, where the stereoscopic images include image parallax and are based on data having a discrete spatial resolution and a predefined surgical plan for the individual. Then, the computer system provides the stereoscopic images to a display. When a surgical tool is advanced, location information of the surgical tool is updated in the stereoscopic images displayed are updated. Alternatively or additionally, When location information indicates a deviation from the predefined surgical plan during the surgical procedure, the computer system generates revised stereoscopic images that indicate: the deviation has occurred an update to the predefined surgical plan and/or how to return to the predefined surgical plan.
