Abstract: A method of detecting whether a receiver coil is near a transmit coil in a wireless power transfer system (WPTS), the method involving: applying a pseudo-random signal to the transmit coil; while the pseudo-random signal is being applied to the transmit coil, recording one or more signals produced within the WPTS in response to the applied pseudo-random signal; by using the one or more recorded signals, generating a dynamic system model for some aspect of the WPTS; and using the generated dynamic system model in combination with stored training data to determine whether an object having characteristics distinguishing the object as a receiver coil is near the transmit coil.

Abstract: A rotary and linear motion device includes a magnetic stator assembly, opposed electromagnetic actuators, and a linear-to-rotary converter (e.g., cam). Each electromagnetic actuator includes a coil that is configured to reciprocate relative to the magnetic stator assembly or to linearly translate in a common direction relative to the magnetic stator assembly. The electromagnetic actuators are coupled to the linear-to-rotary converter and upon reciprocation or linear translation, drive the linear-to-rotary converter in rotary or linear motion. The device may be located inside a wheel, which may be part of a vehicle. If part of a wheel of a vehicle, the device can be used to provide propulsion, steering, braking, and suspension for the vehicle.

Abstract: Instead of being made from one continuous piece of material, a coil includes multiple flat coil segments that are stacked together and electrically coupled in series. In many embodiments, the coil segments are U-shaped segments, and the segments are arranged so that each segment is rotated (e.g., by 270 degrees) with respect the segment it follows. The stacked coils may then be fastened together using, for example, bolts through the corners of the coil segments. The combined coil segments form a continuous coil.
