Abstract: A method and system for transmitting and receiving an audio signal over a video signal in a single cable. The method and system including receiving an analog video signal, the analog video signal comprising one or more rows of video data, an audio header, and one or more quantized audio data. The method includes detecting, the audio header in a blank interval of the analog video and determining a reference level of the audio header. The method and system include extracting, in response to detecting the audio header, the one or more quantized audio data and converting the one or more quantized audio data to an original value of audio data based on the reference level of the audio header.

Abstract: A method for calibrating a projection device, the projection device being equipped with at least two controllable and regulatable light sources, which each transmit a beam component of a scanning beam. The calibration method includes defining a reference beam for the scanning beam; determining, in each instance, a dewarping function for the x-projector coordinate and for the y-projector coordinate of the reference beam, each dewarping function converting the specific projector coordinate to corresponding image coordinates, which are assigned to the image information; determining, in each instance, an offset function for the x-projector coordinate and the y-projector coordinate for all beam components, each offset function approximating the offset between the specific x- or y-image coordinate of the reference beam and the x- or y-image coordinate of the respective beam component.

Abstract: Method for monitoring eyelid opening values. In one embodiment video image data is acquired with a camera which data are representative of a person engaged in an activity, where the activity may be driving a vehicle, operating industrial equipment, or performing a monitoring or control function. When the person's head undergoes a change in yaw angle, such that eyelids of both eyes of the person are captured with the camera, but one eye is closer to the camera than the other eye, a weighting factor is applied, which factor varies as a function of the yaw angle such that a value representative of eyelid opening data based on both eyes is calculated.

Abstract: A smart multimedia content receiver automatically resizes video images based on the content being displayed on the TV screen. Such a self-formatting content receiver includes on-board image processing capability that provides continuous video analysis to detect changes in program formatting and convert each frame as it is received in real time, as opposed to processing and re-releasing an entire program or movie, or relying on the viewer to re-format programs manually. In response to detecting a change, aspect ratio adjustments are made as needed. Because the self-formatting content receiver has access to the video data before it is displayed, such automatic on-the-fly adjustments ensure that the viewer's experience during program changes is seamless and without distortion. Subscribers can influence decisions made by the content receiver by pre-setting viewer preferences for aspect ratio adjustment.

Abstract: Techniques for detecting epileptic triggers in video content by storing a first sequence of frames of a video stream in a first buffer. The technique can further comprise generating a second sequence of subframes and storing the second sequence of subframes in a second buffer. The technique can further comprise generating average intensity values for the second sequence of subframes in the second buffer and calculating intensity changes between consecutive subframes in the second sequence of subframes based on the average intensity values. The technique can further comprise determining that a number of intensity changes between consecutive subframes in the second sequence of subframes exceeds an oscillation threshold and tagging the frames in the first buffer corresponding to the subframes in the second buffer as hazardous.

Abstract: In a projection system, a nonaxisymmetric aspheric surface is used as a surface that is located in a position where in a pencil of light of video image light that exits from each of two points in different corner regions in an image plane that is a light exiting plane of an image display apparatus, light components that should reach a viewer's eyes do not intersect one another, whereby the size of an optical system can be further reduced and the size of an overall apparatus can therefore be reduced with a variety of types of optical precision, such as the resolution and angle of view, maintained.

Abstract: A micro-electro-mechanical device, wherein a platform is formed in a top substrate and is configured to turn through a rotation angle. The platform has a slit and faces a cavity. A plurality of integrated photodetectors is formed in a bottom substrate so as to detect the light through the slit and generate signals correlated to the light through the slit. The area of the slit varies with the rotation angle of the platform and causes diffraction, more or less marked as a function of the angle. The difference between the signals of two photodetectors arranged at different positions with respect to the slit yields the angle.

Abstract: Various patient monitoring systems can include a sensor configured to collect three dimensional information. The systems can identify a location of a patient support surface based on the three dimensional information. The systems can set a two dimensional planar threshold based on the patient support surface. The systems can identify a patient location above the patient support surface based on the three dimensional information and compare the patient location to the two dimensional planar threshold. Exceeding the threshold can be indicative of a high risk of a patient fall. An alert can be generated based on the threshold being exceeded. The systems can repeat the identification of the patient support surface location and the setting of the threshold to account for changes in the patient area.

Abstract: A technique is described herein for using an optical scanning system to visit points in a field along a scanning path. The scanning path includes consecutive passes, corresponding to time-shifted instances of a same scan pattern. The plural passes visit different sets of points within the field, to provide different respective sparse traversals of the field. When motion occurs, the passes evenly distribute the deleterious effects of motion over the field. This produces motion artifacts that resemble blur. The human eye and image processing systems can more effectively handle the presence of blur compared to the kind of motion artifacts produced by a traditional single-pass scanning operation.

Abstract: A drive assist control apparatus assists a driving of a vehicle by controlling a light image projected on a road surface in front of the vehicle. The drive assist control apparatus includes a light image projector, a change portion detector, and a light image corrector. The light image projector projects an informative light image on the road surface. The informative light image represents information to be displayed to an occupant in the vehicle. The change portion detector detects a gradient change portion where a gradient of the road surface changes. The light image corrector corrects a projection position of the informative light image projected by the light image projector. The light image corrector moves the projection position to a position nearer to the occupant than the gradient change portion detected by the change portion detector.
