Abstract: A screen modifier which is light-weight and low cost can be made with a system of apertures and Fresnel lenses to create full depth viewing in almost any existing TV or viewing device. It can be made detachable and adjustable. The effect is wholly natural with no glasses needed. Especially with the newer 4K screens the resulting images are in high definition, or HD. The orderly setup of the screen modifier allows a TV screen to be written to from a remote capture device with data streaming across the Internet in real time. The technology can be applied to TVs, tablets, monitors and cell-phones. It may be useful for remote surgery.

Abstract: An electrical control circuit for a lighting and/or signaling module handling at least two functions from one and the same network of light sources of LED type. The function selection is handled by one or more input signals on the monitoring unit. If a branch or section connected to a defective LED fails, the monitoring unit can either deactivate all the branches or sections, or keep the remaining branches or sections active, and do so according to the function that is present. One or more functions can thus be compared to the single-section type despite the presence of a number of sections when the monitoring unit is configured to deactivate all the sections if one of the sections fails.

Abstract: Systems and methods use cameras to provide autonomous navigation features. In one implementation, a driver-assist object detection system is provided for a vehicle. One or more processing devices associated with the system receive at least two images from a plurality of captured images via a data interface. The device(s) analyze the first image and at least a second image to determine a reference plane corresponding to the roadway the vehicle is traveling on. The processing device(s) locate a target object in the first two images, and determine a difference in a size of at least one dimension of the target object between the two images. The system may use the difference in size to determine a height of the object. Further, the system may cause a change in at least a directional course of the vehicle if the determined height exceeds a predetermined threshold.

Abstract: A profilometer incorporating a partial coherence interferometer directs a beam containing a band of wavelengths along object and reference arms of the interferometer into respective engagements with a test object surface and a reference object surface en route to a spectrometer for measuring a spectrum of the beam. Within the object arm, the test object surface is relatively moved through a range of positions offset from a null position at which optical path lengths of the object and reference arms are equal. Modulation frequencies of the beam spectrum are calculated at a succession of different focus spot positions across the test object surface. Changes in the modulation frequency are interpreted to distinguish between optical path length differences at which the optical path length of the object arm is longer or shorter than the optical path length of the reference arm.

Abstract: The invention deals with a light module, notably for motor vehicles, comprising a reflector with a reflecting surface , a screen arranged facing the reflector, the screen a semi-reflecting area, and a light guide extending longitudinally along the screen and the reflector. The guide comprises a diffusing output face extending transversally from the semi-reflecting area of the screen to the reflector. A portion of the rays exiting from the output face passes through the semi-transparent area, the other portion being also reflected toward the reflecting surface to form successive images with a depth effect of 3D type, without dark areas between these images.
