摘要： Feature vectors used in discrimination of images include information on feature blocks of images in an image-document retrieving apparatus of the present invention. Text areas of a page image document are combined to form rectangular images. On the basis of information on the rectangular images that are extracted, a geometric structure of the page is analyzed, the page image document is divided into plural blocks, and then a plurality of feature blocks describing features of the page document image are selected from the plural blocks. The feature vectors are constituted of information on the feature blocks thus selected. This makes it possible to provide an image-document retrieving apparatus and a method of retrieving image documents, by which retrieval of image documents containing mainly text and a graphic is improvable in accuracy.

摘要： A payment system may intelligently monitor text conversations on other applications or a user's email system. Users and participating merchants may enroll credit cards or other payment devices, bank accounts, etc., with the payment system. Once enrolled, a daemon/plugin of the payment system may monitor text applications, emails, or other communication means of the mobile computing device. Using Artificial Intelligence (AI) and Machine Learning algorithms, the payment system may determine payment information from a text or other communication, and initiate and/or complete a payment transaction between the communicating parties. Upon confirmation, the payment system may complete the funds transfer or payment to registered users or merchants in the text communication. The payment system may also integrate with a merchant's loyalty and reward programs and use these loyalty/reward points as forms of payment.

摘要： Functionality can be implemented for optimizing connection constraints in an integrated circuit design. A target timing path associated with a first of a plurality of sub-connections of the integrated circuit is determined. A timing probability value and a route probability value associated with the first of the plurality of sub-connections is determined based, at least in part, on the target timing path associated with the first of the plurality of sub-connections. The timing probability value indicates a probability that timing closure is satisfied on the target timing path. The route probability value indicates a probability that a physical routing track on the target timing path associated with the first of the plurality of sub-connections resolves congestion. A current connection constraint associated with the first of the plurality of sub-connections is modified in accordance with a connection constraint model to which the first of the plurality of sub-connections corresponds.

摘要： A keypad assembly is described herein in which the keypad assembly includes a substrate and a plurality of domes positioned on the substrate and configured to translate operator action into a corresponding input for a machine. The keypad assembly also includes a dome overlay positioned over the domes and the substrate in which the dome overlay can create a sealed environment for the substrate and the domes. A light guide that directs light in the keypad assembly and an interlocking component coupled to the light guide can also be part of the keypad assembly. In one arrangement, the interlocking component can selectively compress the dome overlay to assist in the creation of the sealed environment. In another arrangement, the interlocking component can compress the dome overlay by bending the dome overlay at an edge of the substrate.
