Abstract:

Collaborative local positioning techniques, such as could be used with smart phones, surveying equipment, or other mobile devices, are described. The techniques include independent techniques for distance measurement between devices, the relative positioning of devices, and an absolute orienting of the devices without use of fixed anchor points and through on-will participation of the devices to provide privacy. Distances between devices are determined by use of a sequence of positioning signals, such as a magnetic signal, each of which include an identifier of the transmitting device, the amplitude of the signal as transmitted, and the position of the signal within the sequence. The amplitude of the positioning signal as received can be compared to the amplitude as transmitted to obtain a distance.

Abstract:

A node in a distributed network computes a hash of content for a service received in a data packet. The node verifies the data packet by comparing the hash of the content of a service received from a neighboring node to a hash of the content computed by the node. An amount of content of the service having a same identification is accumulated in a trusted execution environment (TEE) of the node, and a signature based on code stored in a TEE of the node is generated. The node then sends the data packet to the next neighboring node, where the service-related information includes the service ID, a hash of the service content and the signature. The service records with the accumulated amount of service content, accumulated hash values, and nodes' signatures are sent to the validation nodes to reach consensus for the service provided.

B60W 50/06

Abstract:

A computer implemented method for self-learning of a control system. The method includes creating an initial knowledge base. The method learns first principles using the knowledge base. The method creates initial control commands derived from the knowledge base. The method generates constraints for the control commands. The method performs constrained reinforcement learning by executing the control commands with the constraints and observing feedback to improve the control commands. The method enriches the knowledge base based on the feedback.

Abstract:

An embodiment of the application provides a method for representing internet of vehicles (IOV) knowledge based on a simplicial complex (SC). The method includes: representing k′-dimensional knowledge in a k-dimensional continuous space by using a k-dimensional SC with k′-dimensional function values; and representing a safe boundary of the IOV knowledge by using a boundary of the SC, where the IOV knowledge includes a steering wheel angle of an ego-vehicle, a road curvature, a speed of the ego-vehicle, and an inter-parameter relationship compliant with an objective law of vehicle dynamics, where the steering wheel angle of the ego-vehicle, the road curvature, and the speed of the ego-vehicle are obtained by using a sensor on the ego-vehicle.
