Abstract: A network system can communicate with user and provider devices to facilitate the provision of a network-based service. The network system can identify optimal service providers to provide services requested by users. The network can utilize context data in matching service providers with users. In particular, the network system can determine, based on context data associated with a user, whether to perform pre-request matching for that user. A service provider who is pre-request matched with the user can be directed by the network system to relocate via a pre-request relocation direction. When the user submits the service request after the pre-request match, the network system can either automatically transmit an invitation to the pre-request matched service provider or can perform post-request matching to identify an optimal service provider for the user.

Abstract: An antibacterial and antiviral degradable mask and a manufacturing method thereof are provided. From outside to inside, the mask sequentially comprises a surface layer (1), a core layer (2), and an inner layer (3) that contacts the face; the surface layer (1) is made of an antibacterial and antiviral cellulose spunlace non-woven fabric; the core layer (2) is made of a polypropylene melt-blown non-woven fabric; the inner layer (3) is made of a polypropylene spunbond non-woven fabric or a degradable natural cotton fabric. The mask can have both antibacterial and antiviral functions; moreover, the material is degradable, and thus, environmental pollution pressure caused by non-degradable petroleum-based fiber materials such as polypropylene can be effectively relieved.

Abstract: The application discloses a tire pressure sensor communication method, device, electronic equipment and storage medium. The method comprises the follow steps: acquiring a first tire state when a tire pressure sensor is awakened; collecting first tire pressure data corresponding to the first tire state, and determining whether the first tire state meets a preset state switching condition according to the first tire pressure data; controlling the first tire state to switch to a corresponding second tire state if the first tire state meets the state switching condition; acquiring a preset tire pressure data transmission control parameter corresponding to the second tire state; collecting second tire pressure data corresponding to the second tire state according to the tire pressure data transmission control parameter, and sending the second tire pressure data to a vehicle-mounted tire pressure monitoring module.

Abstract: Provided is a tire pressure monitoring system learning method, device, sensor, system and medium. The tire pressure monitoring system learning method comprises following steps: receiving low-frequency data sent by a low-frequency trigger equipment; determining a command type corresponding to the low-frequency data; acquiring a preset tire pressure data in the low-frequency data if the command type is a sending command of custom high-frequency data, wherein the preset tire pressure data is used for simulating data sent by the tire pressure sensor to a vehicle-mounted ECU in a preset learning scene; generating high-frequency data based on a pre-stored high-frequency configuration parameter and the preset tire pressure data, and sending the high-frequency data to the vehicle-mounted ECU. The technical solution of the application enables the tire pressure sensor to send high-frequency data which can be identified by different vehicle-mounted ECUs, thus improving the adaptability of the tire pressure sensor.
