  • Patent number: 12149231
    Abstract: A switch circuit includes a control unit, a driving unit, a voltage sudden-change unit, and a connection unit. The connection unit is configured to turn on or turn off an electrical connection between a power-supply device and a load. The control unit is configured to control the driving unit to output or stop outputting a driving signal to the connection unit, where the driving signal allows to turn on the connection unit. The voltage sudden-change unit is coupled with a driving node between the driving unit and the connection unit. The control unit is configured to control the voltage sudden-change unit to output a voltage sudden-change signal to the driving node, where the voltage sudden-change signal allows to make the connection unit be switched to a turned-off state from a turned-on state quickly when the driving unit stops outputting the driving signal.

  • Publication number: 20240185846
    Abstract: Techniques for storing and using multi-session context are described. A system may store context data corresponding to a first interaction, where the context data may include action data, entity data and a profile identifier for a user. Later the stored context data may be retrieved during a second interaction corresponding to the entity of the second interaction. The second interaction may take place at a system different than the first interaction. The system may generate a response during the second interaction using the stored context data of the prior interaction.

  • Patent number: 11979045
    Abstract: The present disclosure provides a smart connection device, a jump starter and a battery clamp. The smart connection device includes a power connection terminal coupled to an energy storage module, a load connection terminal coupled to an external load, a switch element, a power supply loop, and a reverse connection detection module. The reverse connection detection module outputs a first control signal to the power supply loop, when the external load is reversely coupled to the load connection terminal. The power supply loop is in a disconnection state and supplies no power to the switch element when it receives the first control signal. The switch element is in an off state when it receives no power supply, to make the power connection terminal and the load connection terminal be in a disconnection state, thereby preventing the energy storage module from providing a discharge output to the external load.
