20180316362, Nov 1, 2018

Filed:

Jun 21, 2018

Appl. No.:

16/014097

Inventors:

- Waltham MA, US
Brian D. Pautler - The Colony TX, US

International Classification:

H03M 1/48
G01D 5/20

Abstract:

A resolver to digital converter is provided and includes first and second inputs to receive signals from a resolver and an output to provide an estimated angle of a rotor. The sine component signal is multiplied by the cosine of the estimated angle and the cosine component signal is multiplied by the sine of the estimated angle, and a difference between them is calculated to provide an error measurement. The estimated angle is updated by the error measurement.

Abstract:

A reinforced plastic composite structure includes multiple layers, with at least one layer including an electrically-conductive element incorporated in a fabric substrate. A fabric substrate with an electrically-conductive element can be referred to as an e-textile. The electrically-conductive element of the electrically-conductive fabric layer is connected to a controller for analysis of the fabric's changing electrical properties over time as a way to identify and prevent failure of the composite structure.
