Abstract: In described examples, a system includes a transformer including a primary winding and a secondary winding. The system also includes a primary side circuit coupled to the primary winding of the transformer. The primary side circuit includes a primary controller. The system further includes a secondary side circuit coupled to the secondary winding of the transformer. The primary controller coupled to cause the primary side circuit to transfer power and intermittently transmit data to the secondary side circuit via the primary winding and the secondary winding of the transformer.

Abstract: An integrated circuit is described herein that includes a semiconductor substrate. First and second piezoresistive sensors are on or in the substrate where each have a respective sensing axis extending in first and second directions respectively parallel with a surface of the substrate, where the second direction is perpendicular to the first direction. A third piezoresistive sensor is on or in the substrate and has a respective sensing axis extending in a third direction parallel with the surface of the substrate and neither parallel nor perpendicular to the first and second directions.
