    Abstract: The present disclosure is directed to a device and method for lid angle detection that is accurate even if the device is activated in an upright position. While the device is in a sleep state, first and second sensor units measure acceleration and angular velocity, and calculate orientations of respective lid components based on the acceleration and angular velocity measurements. Upon the device exiting the sleep state, a processor estimates the lid angle using the calculated orientations, sets the estimated lid angle as an initial lid angle, and updates the initial lid angle using, for example, two accelerometers; two accelerometers and two gyroscopes; two accelerometers and two magnetometers; or two accelerometers, two gyroscopes, and two magnetometers.

  • Patent number: 12261597
    Abstract: In embodiments, a capacitance is coupled to a source of electrical charge via a drain to source current flow path through a field-effect transistor. The capacitance is pre-charged by making the field-effect transistor selectively conductive in response to the gate-source voltage of the field-effect transistor exceeding a threshold. The difference between the gate-source voltage of the field-effect transistor and the threshold provides an overdrive value of the field-effect transistor. The gate of the field-effect transistor is driven with a variable gate-source voltage having as a target maintaining a constant overdrive value. Electrical charge is controllably transferred from the source to the capacitance via the drain to source current flow path through the field-effect transistor avoiding undesirably high inrush currents.
