Abstract: Techniques for electromechanical actuation are provided. In some embodiments, the techniques may involve detecting a rising edge of an input command signal at an input terminal of an electromechanical actuator driver circuit. The techniques may further involve responsive to detecting the rising edge, triggering a state counter until a falling edge of the input command signal is detected. The techniques may further involve responsive to detecting the falling edge, buffering a value of the state counter. The techniques may further involve determining a driver state based on the buffered value of the state counter. The techniques may further involve applying a driver command signal based on the determined driver state.

Abstract: A linear voltage regulator with isolated supply current is disclosed. The voltage regulator is configured and controlled such that its output current closely matches its input current (any quiescent current consumed by the regulator is negligible relative to the amount of current passed by the regulator). In certain implementations, the voltage regulator is implemented as an analog component. In other implementations, the voltage regulator includes or cooperates with digital elements, such as an analog-to-digital converter, a digital processing core, or a digital-to-analog converter.

Abstract: Embodiments are provided for dynamic management of charge. The techniques may involve obtaining an estimated readiness time for an energy storage element, obtaining a target state of charge for the energy storage element, calculating an estimated charging time based at least in part on a difference between the target state of charge and a current state of charge, using a first charging rate to charge the energy storage element to an intermediate state of charge, and responsive to determining the amount of time remaining before reaching a second estimated readiness time is less than an updated estimated charging time to charge the energy storage element at the intermediate state of charge to the target state of charge, using a second charging rate to charge the energy storage element to the target state of charge, wherein the second charging rate is greater than the first charging rate.

Abstract: Devices, systems and methods are provided for networked dynamic management of charge. A processor-implemented method involves charging an energy storage element from an initial state of charge to a holding state of charge, maintaining the energy storage element at the holding state of charge, receiving, via a network, an indication to complete charging the energy storage element, and in response to receiving the indication, charging the energy storage element from the holding state of charge to a target state of charge.
