  • Patent number: 12243526
    Abstract: Determining whether, upon cessation of a second automated assistant session that interrupted and supplanted a prior first automated assistant session: (1) to automatically resume the prior first automated assistant session, or (2) to transition to an alternative automated assistant state in which the prior first session is not automatically resumed. Implementations further relate to selectively causing, based on the determining and upon cessation of the second automated assistant session, either the automatic resumption of the prior first automated assistant session that was interrupted, or the transition to the state in which the first session is not automatically resumed.

  • Patent number: 10088856
    Abstract: Methods, apparatus, systems and articles of manufacture for negative output voltage active clamping using a floating bandgap reference and temperature compensation are disclosed. An example load switch includes a floating bandgap reference circuit to generate a bandgap reference voltage. A resistor divider is to generate a resistor divider voltage. A temperature compensator to apply a temperature compensation current to the resistor divider to create a temperature compensated resistor divider voltage. A power transistor is to be enabled when the temperature compensated resistor divider voltage is less than the bandgap reference voltage. The example load switch can work under negative output voltage clamping and get better accuracy drain to source clamped voltage of power transistor for inductive load condition.
