Abstract: Interferometric modulators may include a movable layer including both permanently anchored and programmable hinges. Unactuated programmable hinges may exert little or no force on the movable layer. When actuated, programmable hinges may exert a mechanical force on the movable layer in a direction approximately opposite to the direction of force exerted by the permanently anchored hinges. By increasing a voltage between the programmable hinges and an electrode, a progressive number of programmable hinges may be engaged. The mechanical force exerted on the movable layer by these hinges may change the relative position of the movable layer within an IMOD device.

Abstract: Techniques are disclosed for performing robust feature matching for visual search. An apparatus comprising an interface and a feature matching unit may implement these techniques. The interface receives a query feature descriptor. The feature matching unit then computes a distance between a query feature descriptor and reference feature descriptors and determines a first group of the computed distances and a second group of the computed distances in accordance with a clustering algorithm, where this second group of computed distances comprises two or more of the computed distances. The feature matching unit then determines whether the query feature descriptor matches one of the reference feature descriptors associated with a smallest one of the computed distances based on the determined first group and second group of the computed distances.

Abstract: Second harmonic nanoprobes for imaging biological samples and a method of using such probes to monitor the dynamics of biological process using a field resonance enhanced second harmonic (FRESH) technique are provided. The second harmonic generating (SHG) nanoprobes are comprised of various kinds of nanocrystals that do not possess an inversion symmetry and therefore are capable of generating second harmonic signals that can then be detected by conventional two-photon microscopy for in vivo imaging of biological processes and structures such as cell signaling, neuroimaging, protein conformation probing, DNA conformation probing, gene transcription, virus infection and replication in cells, protein dynamics, tumor imaging and cancer therapy evaluation and diagnosis as well as quantification in optical imaging.

Abstract: A method for feature matching in image recognition is provided. First, image scaling may be based on a feature distribution across scale spaces for an image to estimate image size/resolution, where peak(s) in the keypoint distribution at different scales is used to track a dominant image scale and roughly track object sizes. Second, instead of using all detected features in an image for feature matching, keypoints may be pruned based on cluster density and/or the scale level in which the keypoints are detected. Keypoints falling within high-density clusters may be preferred over features falling within lower density clusters for purposes of feature matching. Third, inlier-to-outlier keypoint ratios are increased by spatially constraining keypoints into clusters in order to reduce or avoid geometric consistency checking for the image.

Abstract translation: 提供了图像识别中特征匹配的方法。 首先，图像缩放可以基于用于图像的尺度空间上的特征分布来估计图像尺寸/分辨率，其中使用不同尺度的关键点分布中的峰值来跟踪主要图像尺度并粗略跟踪对象尺寸。 其次，代替使用图像中的所有检测到的特征进行特征匹配，可以基于检测到关键点的聚类密度和/或比例级别来修剪关键点。 落入高密度群集中的关键点可能优于落入低密度群集中的特征，用于特征匹配。 第三，通过将关键点空间约束成簇，从而增加关键点比率，以减少或避免图像的几何一致性检查。

Abstract: A phased array antenna system and method employs a phase delay network to provide a scan angle control signal to respective mixers, with phase delays that correspond to the lengths of delay lines between antenna elements. The mixers are connected in circuit with their respective antenna elements so that the scan angle is controlled by the frequency of the scan control signal, independent of the operating signal frequency for the antenna elements. The system can be tailored for either beam transmission or reception, and is applicable to both single and dual delay network versions as well as multi-dimensional arrays.

Abstract: An adaptive optical network is provided for the implementation of learning algorithms. The network comprises a double Mach-Zehnder interferometer in conjunction with a photorefractive crystal that functions as a holographic medium. Light from selectable sources on opposite sides of a beamsplitter is passed through the interferometer, at least one arm of which includes a spatial light modulator for imprinting a data pattern on the light. The light is directed into the holographic medium to develop a refractive index grating corresponding to the data pattern. Light from the hologram is sensed by a photodetector that provides a signal to a threshold device. The output of the threshold device is compared with a reference signal to produce an error signal that can be used to select the source of light directed through the network. The interconnections of the optical devices function to compute the inner product between the elements of the data pattern and their weight factors. Selecting the light source and changing the data pattern provide additive and subtractive weight change capability for implementing various learning algorithms.
