  • Publication number: 20240220038
    Abstract: A control method includes obtaining parameter information of a touch assembly of a first electronic device and sending a notification message to a second electronic device based on the parameter information. The parameter information is related to sensing capability of the touch assembly. The notification message is related to an intensity of a signal transmitted by the second electronic device to the touch assembly. The first electronic device is configured to generate touch information based on the signal.

  • Publication number: 20230385878
    Abstract: A method including obtaining real-time observed orders per minute (OPM) data. The method also can include training a prediction model to make a real-time OPM prediction for a current time period, based on the real-time observed OPM data over past time steps based on lagged time steps in a moving average. The method additionally can include determining, in real-time, whether a demand surge exists based on the real-time observed OPM data and the real-time OPM prediction, to generate a first surge modifier. The method further can include when the demand surge exists, generating, in real-time, a sub-hour revenue per click (RPC) prediction for a first sub-hour time interval. The method additionally can include determining, in real-time, the first surge modifier for the first sub-hour time interval. The method further can include uploading, in real-time, the first surge modifier to a dayparting system of a search engine to bypass existing time intervals and modifiers. Other embodiments are described.
