The present disclosure generally relates to methods and devices for providing touch accommodations to users with tremors or other fine motor impairments to improve the accuracy of such users' touch inputs on touch-sensitive surfaces. Such methods and devices include various approaches for compensating for brief, inadvertent touch inputs; touch inputs with inadvertent motion across the touch-sensitive surface; and/or touch inputs with inadvertent recoil contacts. In some embodiments, the touch accommodations are implemented in a software layer separate from the application layer, such as the operating system.

A method can be used to generate a reference clock signal having a reference frequency. N clock sub-signals are generated, where N is greater than or equal to 2. The N clock sub-signals are successively mutually shifted out of phase by ?/N and each clock sub-signal has an elementary frequency that is equal to the reference frequency divided by N. The N clock sub-signals are propagated over propagation paths. The elementary frequency and a length of the longest propagation path are chosen so that each sub-signal has an acceptable degree of deformation. The duration of each sub-signal edge is longer than quarter of the period of the reference frequency. The reference clock signal is generated by EXCLUSIVE OR combining the propagated clock sub-signals at the end of their respective propagation paths.

A stereo distance measuring apparatus includes a first optical camera and a second optical camera, a position-posture calculator, an image corrector, and a stereo distance measuring unit. The first and second optical cameras are provided in an elastic structure part of an aircraft and separated from each other. The first and second optical cameras constitute a stereo camera. The position-posture calculator calculates, on the basis of a displacement amount of the elastic structure part, first and second position-posture information regarding positions and postures of the first and second optical cameras, respectively. The image corrector generates first and second corrected images by correcting, on the basis of the first and second position-posture information, positions and orientations of images taken by the first and second optical cameras, respectively. The stereo distance measuring unit calculates a distance to a photographing target, on the basis of the first and second corrected images.

An area sensor of the present invention has a function of displaying an image in a sensor portion by using light-emitting elements and a reading function using photoelectric conversion devices. Therefore, an image read in the sensor portion can be displayed thereon without separately providing an electronic display on the area sensor. Furthermore, a photoelectric conversion layer of a photodiode according to the present invention is made of an amorphous silicon film and an N-type semiconductor layer and a P-type semiconductor layer are made of a polycrystalline silicon film. The amorphous silicon film is formed to be thicker than the polycrystalline silicon film. As a result, the photodiode according to the present invention can receive more light.

The invention relates to medical imaging and, more specifically, to intraoral dental radiology. The sensor according to the invention includes a series (SPHx) of detection photodiodes for detecting the arrival of an X-ray flash. The series of photodiodes occupies the location of a central column of the matrix of pixels. The signal of the missing pixel in each row can be reconstructed by interpolating the signals provided by the adjacent pixels of the row. The detection photodiodes are identical to the photodiodes of the active CMOS pixels. They are all electrically connected on one side to a reference potential and on the other side to a detection conductor (CD) extending along the series of photodiodes. This detection conductor is connected to a detection circuit (DX) delivering a signal for triggering the capture of an image when the detected current or the variation in this current exceeds a threshold showing that an X-ray flash has been initiated.
