A technique of charging a capacitive load is presented in which the load is charged by current pulses in a sequence of stages. The amplitude of the current pulses in each stage increases from one stage to the next. Transition between stages is triggered by the voltage across the load meeting a threshold requirement, until a target voltage is reached. The slew rate of a rising edge of each current pulse is lower than the sew rate of the falling edge.

A method (300) of foreign object detection for a wireless power transmitter (100, 600). The method (300) includes determining a vector impedance of a near-field communication (NFC) coil (102, 602) with an NFC chip (108, 608). The determined vector impedance includes an impedance amplitude component and an impedance phase component. The impedance amplitude component and the impedance phase component are compared to a baseline impedance amplitude and a baseline impedance phase. A determination as to whether an object is present within an inductive charging area of the wireless power transmitter (100, 600) is made when a difference between the determined vector impedance, and the baseline impedance amplitude and the baseline impedance phase, exceeds a delta threshold. A ping signal is generated with a charging source coil (104, 604) when the object is determined to be present. A foreign object is detected based on whether a response signal to the ping signal is received from the object.

This document describes motion planning with variable grid resolution for graph-search-based planning. An example system includes a processor that obtains an initial pose, a goal pose, and an obstacle map for an environment. The processor uses a motion-planning algorithm to determine a path or trajectory using two or more grid resolutions for a graph-based search. The path includes a series of waypoints, including two-dimensional positional coordinates (and time coordinates if a trajectory), to navigate from the initial pose towards the goal pose. Operation of the host vehicle is then controlled to maneuver along the path using an assisted-driving or autonomous-driving system. In this way, motion planning is performed for the entire path but uses a coarser grid resolution for the portion nearer the goal pose. This allows motion planning for autonomous parking, especially in environments that include static and dynamic objects, to be handled in a more computationally-efficient manner.
