Abstract: A system and method are disclosed for a system determining surface types using motion patterns. In an embodiment, the system receives inertial measurements from a sensor of a vehicle operating on a surface of an unknown surface type. The system generates a prediction of a type of the surface based on the inertial measurements. In some embodiments, the system generates the prediction by performing a fast Fourier transform (FFT) operation on the inertial measurements to generate a set of frequency bins that reflect surface features. In other embodiments, the system generates the prediction by inputting the inertial measurements into a trained machine learning model configured to generate the prediction of the surface type. The system provides for display data representing the prediction on a user device. The system may also determine the speed and/or geographic location of the vehicle using the inertial measurements and the surface type prediction.

Abstract: A data network system implemented through adding IPN servers and HTTPex servers on the traditional data network system; said data network system designates a home IPN server for each network user, and each IPN server is mapped to one or more attributing HTTPex servers. The servers are designed to achieve logon and HTTPex service ID application task for network users; a plurality of IPN servers may be deployed in the network, and the number of them depends on the number of users and the processing capacity of each IPN server. The HTTPex servers are designed to exchange data between the users and transfer billing information to relevant billing devices. A method for data exchange in above system comprises the following steps: each user is registered to an IPN, the user logs on the IPN server, and the application data packets are exchanged between the user and other users through the HTTPex servers.
