Method for generating two-dimensional code and implementing mobile payment by mobile phone

The invention relates to a method for generating a two-dimensional code and implementing mobile payment by a mobile phone. A user can input various payment card information (such as bank card account numbers, credit card account numbers, prepaid card account numbers, and third party payment user account numbers) into the mobile phone, the information is enciphered and stored, and then the two-dimensional code is generated and displayed on a screen of the mobile phone. A merchant scans a pattern of the two-dimensional code through a two-dimensional code identifying and reading device, and after user authentication information (such as two-dimensional code generation time, mobile phone fingerprints and mobile phone positions) and the payment card information are decoded, the user authentication information, the payment card information, consumption amount information of the user, merchant account number information and the like are enciphered and sent to a corresponding payment and settlement system. After receiving the information, a payment and settlement server confirms the payment card information to be true or false according to the two-dimensional code authentication information, and carries out payment transaction. The method has the main advantage that the user can save the information of various payment cards, consumption cards and the like in the mobile phone and realize no-card electronic payment transaction instead of the various payment cards.

Methods and compositions for the manipulation and characterization of individual nucleic acid molecules

A method for observing and determining the size of individual molecules and for determining the weight distribution of a sample containing molecules of varying size, which involves placing a deformable or nondeformable molecule in a medium, subjecting the molecule to an external force, thereby causing conformational and / or positional changes, and then measuring these changes. Preferred ways to measure conformational and positional changes include: (1) determining the rate at which a deformable molecule returns to a relaxed state after termination of the external force, (2) determining the rate at which a molecule becomes oriented in a new direction when the direction of the perturbing force is changed, (3) determining the rate at which a molecule rotates, (4) measuring the length of a molecule, particularly when it is at least partially stretched, or (5) measuring at least one diameter of a spherical or ellipsoidal molecule. Measurements of relaxation, reorientation, and rotation rates, as well as length and diameter can be made using a light microscope connected to an image processor. Molecule relaxation, reorientation and rotation also can be determined using a microscope combined with a spectroscopic device. The invention is particularly useful for measuring polymer molecules, such as nucleic acids, and can be used to determine the size and map location of restriction digests. Breakage of large polymer molecules mounted on a microscope slide is prevented by condensing the molecules before mounting and unfolding the molecules after they have been placed in a matrix.

LNG/L-CNG skid-mounted gas station

The invention discloses a LNG / L-CNG skid-mounted gas station. The LNG / L-CNG skid-mounted gas station comprises a first sled base, a second sled base, a LNG pump sled, a low-temperature storage tank, aL-CNG pump sled and a gas filling machine; the L-CNG pump sled is arranged on the first sled base; the low-temperature storage tank, the L-CNG pump sled and the gas filling machine are integrated onthe second sled base in sequence; an unloading table is additionally arranged at the end, near the gas filling machine, of the second sled base; the end, near the low-temperature storage tank, of thesecond sled base is movably connected with the first sled base; the low-temperature storage tank discharges liquid by the head and tail ends; fences are arranged on two sides of the first sled base and the second sled base; the first sled base is connected with the end, near the low-temperature storage tank, of the second sled base; top cover plates are arranged at the tops of the fences; and thehorizontal plane of the top cover plates is higher than the horizontal plane of the top of the low-temperature storage tank. The LNG / L-CNG skid-mounted gas station has the following beneficial effects: through high integration degree, the country and industry standards are met, and the functions of an integrated gas station are expanded; and through the mode of discharging the liquid by the head and tail ends of the low-temperature storage tank, the generation of BOG is greatly reduced, and the liquid outlet speed is accelerated.

Apparatus and method for generating an overview image of a plurality of images using a reference plane

An apparatus for generating an overview image of a plurality of images comprises a storage unit and an image processor. The storage unit stores a plurality of processed images of the overview image and is able to provide the overview image containing the plurality of processed images at their assigned positions for displaying. The image processor determines feature points of a new image and compares the determined feature points of the new image with feature points of a stored processed image to identify common feature points and to obtain 3-dimensional positions of the common feature points. Further, the image processor determines common feature points located within a predefined maximum distance of relevance to a reference plane based on the 3-dimensional positions of the common feature points to identify relevant common feature points. Further, the image processor processes the new image by assigning the new image to a position in the overview image based on a comparison of an image information of each relevant common feature point of the new image with an image information of each corresponding relevant common feature point of the stored processed image without considering common feature points located beyond the predefined maximum distance of relevance to the reference plane.
