Abstract: A liquid crystal composition includes at least one compound of general formula F and at least one compound of general formula N. A liquid crystal display device includes the liquid crystal composition. The liquid crystal composition has a larger K value, a smaller rotational viscosity, a higher VHR value, a longer low temperature storage time and a shorter response time while maintaining an appropriate clearing point, an appropriate optical anisotropy, and an appropriate absolute value of dielectric anisotropy, such that the liquid crystal display device including the liquid crystal composition has a better contrast, a wider temperature range for application, a faster response speed, a better contrast and a higher reliability.

Abstract: A technique is presented for quantizing pixels of an image using Sigma Delta quantization. In one aspect, pixel values for an image are segmented into columns of pixel values; and for each column in the matrix, pixel values of a given column are quantized using sigma delta modulation. The pixel values in a given column are preferably quantized as a whole, thereby minimizing accumulated quantization error from a starting pixel value in the given column to a current pixel value in the given column. In another aspect, the pixels of an image are quantized using a 2D generalization of Sigma Delta modulation.

Abstract: An electronic system includes a display interface configured to display a calibration point; a sensor, coupled to the display interface, and configured to capture a first gesture directed at the calibration point from a first position; capture a second gesture directed at the calibration point from a second position, wherein the second position is different from the first position; and a control unit, coupled to the display interface, and configured to display a position indicator on the display interface based on a directive gesture captured by the sensor, the first gesture, and the second gesture.

Abstract: An electronic system includes a control unit, configured to identify a first sensor reading for capturing a gesture directed at a display interface using a first range profile; identify a second sensor reading for capturing the gesture directed at the display interface using a second range profile; calculate a blended position indicator based on the first sensor reading, the second sensor reading, or a combination thereof; and a communication interface, coupled to the control unit, configured to communicate the blended position indicator by generating a cursor at the blended position indicator.

Abstract: An input method and apparatus is provided for use in various computer and mobile devices. The input device utilizes a rotating dial in which four arrows printed on the dial are rotated to select characters that are fixed along the circumference of a circle. The characters are divided into various zones. The zones are utilized to encode various letters and numbers. Additionally the zones may be utilized for editing and control functions. The dial may be freely rotated. Pressing any arrow inputs the character that the arrow points to on the dial. The input device and method may encode Asian language characters according to a set of encoding rules.

Abstract: Embodiments of the invention determine whether an image has been altered. Sets of patches are selected in the image, and corresponding inverse response functions are provided to a support vector machine (SVM). The support vector machine is trained with exemplary normal and abnormal inverse response functions. Once trained, the support vector machine analyzes inverse response functions corresponding to a suspected image. The support vector machine determines if the inverse response functions are normal or abnormal by analyzing a set of features. In one embodiment, features include measures for monotonic characteristics, fluctuation characteristics, and divergence characteristics of the red, green, and blue components of a tuple. Each tuple of inverse response functions is associated with a set of patches selected in the image.
