Abstract: A device for rotary or linear position sensing includes a stator with a plurality of teeth, an excitation winding wrapped around at least some of the plurality of teeth, and multiple sense windings for detecting changes in voltage output. The windings are in two sets in which each set can independently determine the change in voltage output. A control circuit generates a first output signal representing a relative position of the stator based on excitation of the first sense winding set by the excitation winding and a second output signal representing a relative position of the stator based on excitation of the second sense winding set by the excitation winding.

Abstract: A power system with a reliability enhancing battery architecture for electric motors adapted for use in an aerial vehicle. Individual batteries may be used to power a subset two or more motors in systems with six or more motors, for example. Each motor may be powered may be powered by two or more subsets of batteries, allowing accommodation for motor failure. With a failed motor in a vertical take-off or landing mode, power may be diverted to other motors to continue proper attitude control, and to provide sufficient thrust. With a failed motor a second motor offset from the failed motor may be powered down to facilitate attitude control.

Abstract: The power system can include: a plurality of batteries, a plurality of electric propulsion units, flight computers, and power connections. The propulsion assemblies can include a motor, a propeller, and one or more inverters. The power system can optionally include a plurality of flight actuators. However, the power system can include any other suitable set of components. The power system functions to provide aircraft propulsion and/or aircraft control authority during flight.
