  • Patent number: 12095327
    Abstract: The slot liner (13) includes a laminated insulation sheet (131) having a length (L1) longer than a length (L2) of a stator core in an axial direction and a pair of reinforcing sheets (135, 136).

  • Publication number: 20220365484
    Abstract: A new diversity concept is provided for achieving accurate phase retrieval with a singleshot acquisition. Multiple irradiance data are obtained by a diffractive grating or CGH designed to generate multiple diffraction orders with different diversity values. The effective filters associated with the individual diffraction orders from the diffractive grating or CGH are calculated. The effective filters are extracted by numerical propagation, and they preferably include both real and imaginary values, which signify both absorption and phase shift versus position in the filter plane. The reconstruction process utilizes accurate knowledge of the effective filters for each diffraction order for high quality reconstruction of the extrinsic phase.
