摘要:
Embodiments for providing an arbitrary control flow architecture for an arbitrary waveform generator (AWG) are generally described herein. In some embodiments, an arbitrary control flow instruction set defines control operations for generating an arbitrary waveform. A processor is arranged to execute the arbitrary control flow instruction set from data stored in a system memory to generate an arbitrary waveform. A system memory may include a low-latency memory and a high-latency memory, wherein a cache controller may use prediction mechanisms to reduce the latency of fetching instruction and waveform data by copying that data to the low-latency memory before it is requested.

A method for range finding of a target including: generating a first photon and a second photon identical to the first photon; transmitting the first photon towards the target and delaying the second photon by a time delay; receiving the first photon reflected from the target and the delayed second photon; interacting the reflected first photon and the delayed second photon to produce HOM interference; detecting photo-statistics at an output of the HOM interference; when the two photons are output at the same output port, repeating the above processes; when the reflected first single photon and the delayed second single photon are output at different output ports, changing the time delay and repeating the above processes; repeating the above processes for a number of times to arrive at a final estimate for a value of the time delay corresponding to the final estimate of the target range.

Embodiments of a system and method for finding optimal routes for simultaneous transmissions over broadcast medium are generally described herein. In some embodiments, nodes are placed into a cost matrix representing a connected graph of nodes, virtual nodes are identified by applying matrix operations to the cost matrix and backtracking is performed incrementally to build candidates of virtual nodes for a solution set from the identified virtual nodes and to eliminate unsuitable candidates.

A method for feature transformation of a data set includes: receiving a data set including original feature samples with corresponding class labels; splitting the data set into a direction optimization set and a training set; using the direction optimization set to calculate an optimum transformation vector that maximizes inter-class separability and minimizes intra-class variance of the feature samples with respect to corresponding class labels; using the optimum transformation vector to transform the rest of the original feature samples of the data set to new feature samples with enhanced discriminative characteristics; and training a classifier using the new feature samples, wherein the method is performed by one or more processors.

A reconfigurable aperture includes a plurality of metallic particles confined to a volume extending across an aperture area. The metallic particles are repositioned within the volume to form opaque regions in the aperture area. The opaque regions, and transmissive regions between the opaque regions, can form a reconfigurable zone plate that can change the collimation of a microwave beam via diffraction therethrough. The zone plate can be located a fixed distance away from a microwave source and a detector in a housing, so that for any specified wavelength produced by the microwave source, the zone plate can reconfigure to have a focal length equal to the fixed distance. The reconfigurable zone plate can effectively collimate microwaves produced by the microwave source, can direct the collimated microwaves in a specified direction, can receive microwaves returning along the specified direction, and can focus the received microwaves onto the detector.

A system facilitates the browsing of information of interest. The system obtains a transcription of the information and provides the transcription to a user. The system also retrieves the information in its original format and presents the information to the user in the original format. The system visually synchronizes the presentation of the information in the original format with the transcription of the information
摘要:
Provided are systems and methods for detecting and associating location information with changes in capacitance on a capacitance sensor assembly of a computing device. Enhancing capacitance detection to include location information can enable generation of image data for display to user showing properties of a concealed object. Rates of change in capacitance drain detected at the sensor assembly coupled with location information can be stored in a derivative image format. The derivative image format of a concealed object can be transformed into an approximation of a conventional camera image. Further processing can be executed to define properties of the concealed object, and identify the concealed object. Further processing can also include model-based analysis and/or property matching to known objects. Image displays can also be correlated to subsequent positions of the device, allowing “x-ray” views of concealed objects

An optical imaging system and method for performing random intensity illumination microscopy is disclosed. The system includes an incoherent signal light source, at least two diffusers having spatially random diffusion patterns, an image capture device that receives a reflected light signal from an object to be imaged, and a processor configured to perform digital image processing of the reflected signal. The method comprises acts of providing an incoherent light signal, diffusing the incoherent light signal with at least two diffusers having spatially random diffusion patterns to provide a diffused light signal, splitting the diffused light signal to provide a first light signal and a second light signal, reflecting the first light signal from a specimen to provide a reflected light signal, collecting the reflected light signal and the second light signal with an image capture device and processing the collected images to determine reflectance.
