Abstract: A grapevine soil-cleaning device and engineering machinery installed with the soil-cleaning device, comprising an air blower (4), an air vent direction reversal device, a soil-retaining device, an angular sensor (7) and a controller (19). The controller (19) is connected to the air blower (4), the angular sensor (7), the air vent direction reversal device and the soil-retaining device respectively. The present device achieves non-contact soil cleaning by blowing air, and has the advantages of no harmful impact on buds and branches, one-time cleaning, and highly efficient soil cleaning. The air vent direction reversal device may achieve a consistent air-blowing direction when the grapevine soil-cleaning device moves among rows of the grapevine. The soil-retaining device may hold back the blown soil and reduce the displacement distance of the blown soil.

Abstract: An identity identification method comprises: tracking a current location of each user to determine a current grid area each user is located; receiving an identification request sent by a service terminal; the identification request comprises first location information and biological characteristic information of a target object; determining a first grid area where the service terminal is located based on the first location information; obtaining biological characteristic information of each user with respective current grid area being the first grid area; completing an identity identification according to the biological characteristic information of the target object and the biological characteristic information of each user in the first grid area. A device and server based on dynamic rasterization management are further provided.

Abstract: This application provides an identity Identification method for a fixed-point authorization, and devices and servers therefor, comprises receiving an identification request sent by a service terminal; wherein the identification request comprises terminal information and live body biological characteristic information of a target object; the terminal information comprises a terminal merchant number and terminal location information; determining at least one valid user of the service terminal according to the terminal information, and obtaining biological characteristic information of each valid user; wherein the valid user has a direct or an indirect authorization relationship with the service terminal; completing the identity identification according to the live body biological characteristic information of the target object and the biological characteristic information of each valid user.

Abstract: USB bus enumeration and configuration switching in a dual-processor architected device can result in loss of the inter-processor communication link. In order to solve this problem, an apparatus, architecture and method for simplifying the Universal Serial Bus (USB) service enumeration between two processors in a dual-processor architecture device are provided. A USB host (102) is connected to a first processor (201) of the dual-processor device (100) via a USB cable (104). The first processor (201) begins to enumerate services to the connected host (102). When the host sends a set_configuration request (405) to the device (100), the device determines whether the first processor (201) and the second processor (203) have the same configuration sets. The first processor (201) sends a set_configuration request to the second processor (203) to setup the requested services in the second processor.
