摘要:
Methods include providing an article including a substrate, a first layer supported by the substrate, and an interface between the substrate and the first layer. The substrate is substantially transparent to radiation at a wavelength λ and the first layer is formed from a photoresist. The methods include exposing the first layer to radiation by directing radiation at λ through the substrate to impinge on the interface so that the radiation experiences total internal reflection at the interface.

In general, in one aspect, the invention features an apparatus that includes a plurality of optical elements arranged to form an image of an object. The elements include a first element comprising one or more regions of a polarizing material, the regions being shaped as one or more visual features, a polarizer, and a mounting assembly including a first mount for the first element and a second mount for the polarizer. At least the first or second mount is rotatable with respect to an optical axis between a first orientation and a second orientation. In the first orientation, the visual features are visible in the image of the object and, in the second orientation, the visual features are not visible in the image of the object.

The present disclosure provides a method and device for transmitting recommended product information. In one embodiment, a system retrieves product evaluation records given by one or more users. Each of the product evaluation records includes an identification of the user (user ID), an identification of the product (product ID), and evaluation information. The system uses the user ID and the product ID as a primary key, and then, based on intervals of the primary key, divides the product evaluation records into several subsets of records, and assigns these subsets of records into multiple calculation nodes. The system retrieves such SVD calculation results of the multiple subsets of records from the multiple calculation nodes. The recommended product information is sent to a client terminal based on the SVD calculation results. The present disclosure implements the distribution processing of SVD calculation, reduces the calculation complexity, and saves the calculation time.

A method for implementing verification and payment in content services includes: pre-configuring a payment-related interface between a content service provider and an instant messaging service provider; providing the payment-related interface in a function library providing the instant messaging service's login verification interface; modifying the function library and a first jar package including a content service program provided by the content service provider, which includes: injecting the login verification interface and the payment-related interface into the first jar package and configuring the login verification interface as to be called before the content service program is executed; and combining the modified first jar package and function library to form a second jar package, modifying the value of attributes originally belonging to the first jar package in the second jar package to make the modified value of the attributes reflect corresponding attributes of the second jar package.
摘要:
A reconfigurable integrated circuit (IC) has IC interface terminals including circuit input terminals and circuit output terminals. A bypass controller and bypass circuitry are coupled to each other, and to at least one of the circuit input terminals and at least one of the circuit output terminals. A processing circuit has multiple circuit modules coupled to the bypass circuitry. The processing circuit is coupled to at least one of the circuit input terminals and at least one of the circuit output terminals. In operation the bypass controller controls the bypass circuitry to selectively couple at least one pair of the IC interface terminals together, the pair including one of the circuit input terminals and one of the circuit output terminals. When the pair of IC interface terminals are coupled together, at least one of the circuit modules is selectively de-coupled from the pair of the IC terminals.
