A method for processing a natural language query. The method includes receiving a text query, the query referring to a plurality of objects, attributes, qualifiers and other arguments and parsing the query to produce an argument tree representing the substance and structure of the query. The method also includes the capability to define qualifiers as being possibly projectable onto other arguments and indicate their direction of projectability and the capability to denote nodes of the argument tree as foldable, as splittable, or as containing sequences of qualifier arguments. The method additionally includes defining validity rules for a domain of knowledge, used to determine whether a list of arguments form a valid granular query component and processing of the argument tree, in view of the above in order to derive a corresponding plurality of granular query components that collectively request the plurality of pieces of information representing the intent of the query.

Systems and methods for granularizing compound natural language queries

A digital pulse controller uses digital logic to send pulses to a high side and low side switches of a switch-mode power supply converter. The digital logic uses a pulse frequency mode which includes a frequency targeting mode and an ultrasonic mode. The frequency targeting mode dynamically adjusts the size of the pulses in order to achieve a switching frequency within a desired band. The ultrasonic mode is switched into when the frequency of the pulses are at or below a threshold and the time of the pulses reaches a minimum threshold.

A controller produces high-side and low-side control signals. The high and low-side signals are used to switch high-side and low-side transistors in the power stage to control the voltage across the power stage output capacitor of the power stage. A boost feedback charge pump receives the low or high-side signal to increase the charge on a charge pump output capacitor. The controller is configured to send Pulse Frequency Modulation (PFM) high and low-side signals that control the voltage on the power stage output capacitor and charge the charge pump output capacitor. The controller is also configured to send boost feedback (BFB) high and low-side signals that charge the boost feedback capacitor, but are designed to not significantly change the charge on the power stage output capacitor.
