Abstract: The invention generally relates to a method and system for utilizing an Artificial Intelligence (AI)-based technology for tracking human mobility patterns and contact points, via a Software Development Kit (SDK) integrated into client device applications. The SDK performs contact tracing by recording past and current signal data/measurements of Wi-Fi access points encountered by a client device and stores these measurements in a local memory of the client device. The SDK further analyses the recorded past and current signal data/measurements of the Wi-Fi access points using an AI module to derive mobility patterns of user of the client device. The AI module of the SDK then identifies other client devices that the client device may have encountered based on analyzing the mobility patterns of the user of the client device and the recorded past and current signal data/measurements and via performing Wi-Fi network sniffing.

Abstract: This disclosure provides systems, methods, and apparatus related to Li-ion batteries. In one aspect an electrolyte structure for use in a battery comprises an electrolyte and an interconnected boron nitride structure disposed in the electrolyte.

Abstract: The invention provides a method and system for sharing Wi-Fi in a Wi-Fi network using a cloud platform. To start with, the method and system enables registration of one or more Wi-Fi access points on the cloud platform and enables a client device to rent a Wi-Fi connection from owner of a Wi-Fi access point. Subsequently, the method and system enables the client device to select a Wi-Fi access point registered on the cloud platform based on usage fee, properties and signal quality. Further, the method and system performs offload optimization using an AI module by deciding whether data offloading from licensed spectrum to unlicensed spectrum is desirable or not. In response to deciding that data offload is desirable, the client device is allowed to connect to the selected Wi-Fi access point and transact with the Wi-Fi access point owner using cryptocurrencies in a blockchain-based network.
