Abstract:
The configurations of a resonant converter system and a controlling method thereof are provided. The proposed resonant converter system includes a resonant converter receiving an input voltage for outputting an output voltage, a rectifying device having a first rectifying switch and a synchronous rectification control circuit coupled to the resonant converter and including a signal generation apparatus generating a weighted turn-off signal to turn off the first rectifying switch at a zero crossing point of a first current flowing through the first rectifying switch.

A reflection repressed wire-grid polarizer device for polarizing incident visible or infrared light and selectively repressing a reflected polarization includes at least three layers disposed on a substrate. A polarizing wire-grid layer has an array of parallel metal wires with a period less than half the wavelength of the incident light. A reflection-repressing layer or grid includes an inorganic and non-dielectric material which is optically absorptive of visible or infrared light. A dielectric layer or grid includes an inorganic and dielectric material.
Abstract:
An advertisement image classification system trains a binary classifier to classify images as advertisement images or non-advertisement images and then uses the binary classifier to classify images of web pages as advertisement images or non-advertisement images. During a training phase, the classification system generates training data of feature vectors representing the images and labels indicating whether an image is an advertisement image or a non-advertisement image. The classification system trains a binary classifier to classify images using training data. During a classification phase, the classification system inputs a web page with an image and generates a feature vector for the image. The classification system then applies the trained binary classifier to the feature vector to generate a score indicating whether the image is an advertisement image or a non-advertisement image.

Abstract:
An object search system generates a hierarchical clustering of objects of a collection based on similarity of the objects. The object search system generates a separate hierarchical clustering of objects for multiple features of the objects. To identify objects similar to a target object, the object search system first generates a feature vector for the target object. For each feature of the feature vector, the object search system uses the hierarchical clustering of objects to identify the cluster of objects that is most “feature similar” to that feature of the target object. The object search system indicates the similarity of each candidate object based on the features for which the candidate object is similar.

Abstract:
This invention releases the preparation method and equipment of graphite and catalyst composite for a kind of synthetic diamond. Firstly the clean graphite particle shall be placed into the heating chamber for pre-heating, the lower limit of the heating temperature shall be higher than the boiling point of the coated carbonyl metal complex and the upper limit of the heating temperature shall be set according to the thickness of the coating needed; secondly, the heated graphite particle will be fed into the coating room with vibrator or agitator and the steam of carbonyl metal complex shall be input for coating; finally the coated graphite particle shall be fed into the cooling and passivation room for cooling and passivation of the discharging materials or enter the next round circle of heating and coating. As to the graphite and catalyst composite prepared by this invention, the surface of each graphite particle is plated with metal layer and the continuous metallic contact is formed between the particles of the synthetic cylinder prepared by it. In synthesis, it is easy to form the continuous metallic film so as to continuously feed the carbon to the diamond crystal nucleus to promote the crystal nucleus growing into perfect diamond crystal.
Abstract:
An inorganic, dielectric grid polarizer device includes a stack of film layers disposed over a substrate. Each film layer is formed of a material that is both inorganic and dielectric. Adjacent film layers each have different refractive indices. At least one of the film layers is discontinuous to form a form-birefringent layer with an array of parallel ribs having a period less than 400 nm. Another layer, different than the form-birefringent layer, is formed of an optically absorptive material for the ultra-violet spectrum.

An optical data storage system includes a laser diode to produce at least one light beam. An inorganic, dielectric grid polarizing beam splitter is disposable in the light beam to transmit a polarized light beam, and includes a stack of film layers disposed over a substrate. Each film layer is formed of a material that is both inorganic and dielectric. Adjacent film layers have different refractive indices. At least one of the film layers is discontinuous to form a form birefringent layer with an array of parallel ribs with a pitch of less than 390 nm. A drive carries a disc medium disposed in the polarized light beam to reflect a modified light beam. The grid polarizer is disposable in the modified light beam to separate the modified light beam into a reflected beam and a transmitted beam. A photo-detector is disposable in the reflected or transmitted beam.
Abstract:
A cube wire-grid polarizing beam splitter includes a pair of prisms secured together to form a cube. An array of parallel conductive wires is disposed between the pair of prisms. A pair of continuous film layers is disposed on one side of the wires between the wires and one of the pair of prisms with an intermediate film layer adjacent the prism having a refractive index greater than both i) a refractive index of a rear film layer adjacent the plate wire grid polarizer, and ii) a refractive index of an adjacent prism. A layer of ribs is disposed on another side of the wires between the wires and another of the pair of prisms, the ribs being aligned with and supporting the array of parallel conductive wires.
