Abstract: A sensor package (100; 100a; 100b) for sensing rotational positional data includes a stack of separated printed circuit boards that includes a first position target printed board (126), a second printed circuit board (120) having a rotary sensor and a third printed circuit board (140) having power supply components. The sensor package is included in a skew detection system (200) for an aircraft control system, which includes a control surface (210) having opposed first (210a) and second (210b) ends. A first drive mechanism (220a) is operatively connected to the first end of the control surface by a first rack and pinion assembly (230a) and a second drive mechanism (220b) is operatively connected to the second end of the control surface by a second rack and pinion assembly (230b). Each rack and pinion assembly includes a respective sensor package (100a, 100b) operatively connected to the pinion (234a, 234b) thereof. A processing component (240) is operatively connected to both sensor packages to determine presence of skew in the control surface.

Abstract: An inductive rotational speed sensor assembly (100) includes a first PCB (10) with a transmitter coil (12) configured to convert an alternating electrical input into an alternating magnetic field. A second PCB (20) is operatively connected to the first PCB for relative rotation and includes a resonance coil (25; 25, 25A) in combination with a capacitor configured to couple to the alternating magnetic field of the first PCB to output a modulating position signal. The first PCB includes a receiver coil (15; 15, 15A) configured to receive the first and the modulating position signal and to output a signal indicative of rotational speed of the second PCB relative to the first PCB, derived from the frequency or time separation between pulses in the received signal indicating a high coupling between transmitter and receiver coil.
