Abstract: To provide a control system of a stereo imaging device that is able to obtain a stereo image, which can be viewed stereoscopically, even when relative-position relationship of a pair of imaging units is unknown. A control system of a stereo imaging device includes a pair of imaging units, an error calculation unit and a control unit. A pair of the imaging units has a digital or analog degree of freedom so as to be able to control at least a yaw, pitch, roll and zoom factor, and can capture video frames using imaging elements. The error calculation unit uses each of images captured by a pair of the imaging units to calculate a rotating error and zoom error of each imaging unit on the basis of a difference from a predetermined standard convergence model of each imaging unit.

Abstract: Disclosed in this specification is a method for treating a contact lens mold surface with ultraviolet light to increase the surface's wettability. Such molds are useful in manufacturing contact lenses by disposing a reaction mixture between a concave frontcurve mold and a convex basecurve mold prior to polymerization. By adjusting the wettability of the convex and concave surfaces, as well as the wettability of the surrounding flange, the demolding of the resulting contact lens better controlled and defects are reduced.
Abstract: The present invention relates to an optical lens having a lens element produced of plastic, more particularly of plastic which is transparent in a visible spectral range, and having a coating comprising a plurality of layers, the plurality of layers comprising at least one high-refractive-index layer. Furthermore, a hardcoat layer is formed adjacent to the lens element, and a superhydrophobic layer concludes the coating in opposition to the lens element. The at least one high-refractive-index layer has a thickness of less than 40 nm, and the coating overall has a thickness of more than about 380 nm.

Abstract: An integrated image sensor circuit with multiple power modes is disclosed. The integrated circuit comprises a pixel array, an analog block to process analog signal associated with the pixel array, where the analog block comprises an analog to digital convertor (ADC), and a first control circuit to enable/disable the analog block or to configure the analog block to a high/low-power mode depending on whether the pixel array is in a readout frame or in a reset frame with no active readout. The integrated image sensor circuit may further comprise a post-processing block and a second control circuit to enable/disable the post-processing block or to configure the post-processing block to the high-power mode or the low-power mode depending on whether the pixel array is in the readout frame or in the reset frame with no active readout.
