Abstract: A binding request for binding a broadcast device is sent to a payment system, wherein, responsive to receiving the binding request, the payment system binds a device identifier of the broadcast device comprised in the binding request to a user account. A payment request corresponding to the user account is sent to the payment system, wherein the payment system processes the payment request. A payment result corresponding to the payment request is received from the payment system, wherein the payment result is sent after the payment system identifies, based on the device identifier, the broadcast device bound to the user account. A payment result voice is output from the broadcast device based on the payment result.

Abstract: The present disclosure provides a method and device for in-vehicle payment. A face image of an in-vehicle user and a geographic location of the in-vehicle user are received at a point of a ride route traveled by a vehicle occupied by the in-vehicle user. An image set associated with the geographic location is received from an image database using the geographic location of the in-vehicle user. The image set includes face images of a plurality of users. The face image of the in-vehicle user is compared with face images in the image set to determine an identity of the in-vehicle user. A fare deduction account corresponding to the in-vehicle user is identified using the identity of the in-vehicle user. A fare corresponding to the ride route is deducted from the fare deduction account.

Abstract: Association information received from a number of mobile devices is recorded at a server end, where each mobile device is associated with a user that is pre-registered with the server end. An identification request is received at the server end and from a cashier device, where the identification request includes identity information associated with a particular user. One or more payment candidates corresponding to the cashier device are determined by the server end. A particular user account corresponding to the particular user is determined by the server end by comparing the identity information from the identification request with identity information associated with each of the payment candidates. The particular user account is returned by the server end to the cashier device for making a payment.

Abstract: A spray-head assembly includes a pipe structure and a valve-spool. The pipe structure includes a liquid inlet, a flow pathway, and a valve-port. The flow pathway includes an air-flow pathway arranged obliquely with respect to a central axis of the liquid inlet. A bottom end of the air-flow pathway communicates with the liquid inlet. The valve-port is arranged at a top end of the air-flow pathway. The valve-spool is arranged in the flow pathway and configured to control opening and closing of the valve-port.

Abstract: An agricultural unmanned aerial vehicle (UAV) includes a fuselage, a flight power apparatus, a plurality of spray nozzles, a plurality of water pumps, and a controller. The flight power apparatus is mounted at the fuselage. The plurality of spray nozzles are installed below the flight power apparatus. The plurality of water pumps are connected to the plurality of spray nozzles and configured to deliver liquid to the spray nozzles. The controller is electrically coupled to the plurality of water pumps, and configured to selectively control one or more of the plurality of water pumps to pump the liquid to one or more of the spray nozzles connected to the one or more of the water pumps.

Abstract: A computer-implemented method comprises: obtaining, by the settlement device, a biometric feature of the user; determining, by the settlement device, that the obtained biometric feature matches a stored biometric feature, wherein the stored biometric feature corresponds to an account identifier; and in response to determining that the obtained biometric feature matches the stored biometric feature, performing, by the settlement device, a settlement of an account associated with the account identifier that corresponds to the stored biometric feature.
