Computer-implemented methods, systems and devices facilitating the methods, and computer-readable medium storing computer readable code, which, when executed, performs the methods are provided for offline coupon verification. The methods may include inputting a verification code of a coupon to a coupon verification terminal, decrypting the verification code using a terminal private key to obtain a merchant ciphertext, decrypting the merchant ciphertext using a merchant-specific server public key to obtain a purchase information corresponding to the coupon, comparing the purchase information with a database to determine whether the purchase information is correct, displaying a negative verification result if the purchase information is not correct, and displaying a positive verification result if the purchase information is correct and the coupon has not been previously consumed, registering the coupon as consumed in the database for future verifications, when or after the coupon been verified, and synchronizing the database with that of a server.

When the gray processing section converts input image data into gray image data, the histogram generating section generates a histogram that represents the distribution of the number of pixels of the gray image data. Then, based on the gray level of a target pixel and the gray levels of a plurality of neighbor pixels surrounding the target pixel in the shape of an approximate circumference, rotation-invariant features indicating local texture feature centering on the target pixel are calculated for each of the pixels, and a histogram is generated based on the calculated feature. Thereafter, the search section searches for similar image data based on the histogram of the registration image data and the histogram of the input image data, and the display section displays the result of search.

An image document processing device extracts a character sequence image having M number of characters in an image document, divides the image into individual character images, extracts features of the individual character images, and based on the features, selects N (N is an integer more than 1) character images in the order of degree of matching from a font-feature dictionary for storing features of all character images according to fonts, and generates an M×N index matrix for the extracted character sequence. In searching, the device searches an index-information storage section with respect to each search character included in a search keyword in an input search expression, and extracts an image document including an index matrix including the search keyword. This provides an image document processing device and an image document processing method each allowing indexing not requiring user's operation and each allowing highly precise searching without OCR recognition.

A method of allocating a physical memory in a specified address range under a Linux system platform is applied in a testing process of a physical memory under a Linux operating system. In this method, according to a specified address range and a size of a memory to be allocated, a large amount of physical memories in the system are allocated in a specified address range, and then the information about the allocated memories is transmitted, so as to map, inspect, and release the memories, thereby effectively supporting the test for physical memories under the Linux operating system.
摘要:
A phase change ink having an ink vehicle, at least one colorant and dispersants, such as at least one polyalkylene succinimide, at least one triamide and/or at least one rosin ester. The dispersants assist in dispersing colorants, such as pigments like carbon black, in non-polar ink vehicles. Also, disclosed are methods of making such phase change inks.

In one aspect, waxy build material inks are described herein which, in some embodiments, exhibit desirable print quality and associated mechanical properties for three-dimensional printing applications. A build material ink, in some embodiments, comprises 20-40 wt. % rosin component, 5-35 wt. % non-polar wax component, and 40-65 wt. % alcohol wax component comprising one or more waxes of the formula (CnH2n+1)OH wherein n is an integer from 15 to 40. In another aspect, a build material ink comprises a eutectic mixture including rosin component, a non-polar wax component, and an alcohol wax component comprising one or more waxes of the formula (CnH2n+1)OH wherein n is an integer from 15 to 40.
摘要:
Methods and systems are provided for authenticating access to a wearable computing device using an authentication object, such as a hand. The wearable computing device comprises a head mountable display (HMD) and an image capture device and has access to a data profile for the authentication object. The wearable computing device provides (e.g., using the HMD) an indication for positioning the authentication object within a field of view of the image capture device. After providing the indication for positioning the authentication object, the wearable computing device receives image data from the image capture device. If the wearable computing device identifies the authentication object in the image data, for example, by matching at least a portion of the image data with data in the data profile, authentication is successful and one or more functions of the wearable computing device can be enabled.
摘要:
A logo device for a vehicle is disclosed. The logo device comprises a first shell including a transparent region forming a logo pattern and a nontransparent region and a second shell connected with the first shell. The first shell and the second shell form a sealed cavity therebetween. A bottom plate is disposed in the sealed cavity, and a light guide plate disposed between the bottom plate and the first shell. The light guide plate includes one or more grooves disposed thereon. A circuit board is disposed between the bottom plate and the second shell, including a plurality of illuminating elements thereon. The one or more grooves on the light guide plate receives the plurality of illuminating elements. The light guide plate is configured to direct at least a part of the light generated by the illuminating element toward the transparent region of the first shell.
摘要:
Substituted oxazoline compounds and/or substituted oxazoline derivatives having amorphous, semi-crystalline, or crystalline properties and methods for producing such compounds and derivatives are presented. The substituted oxazoline compounds and/or substituted oxazoline derivatives are useful for various applications. For example, the substituted oxazoline compounds and/or substituted oxazoline derivatives may function as phase-change agents, a binder resins, rheology modifiers or plasticizers for ink compositions.
