Abstract: A knitted component comprising two yarns, forming at least a heel region of an upper for an article of footwear, where one of the yarns comprises a thermoplastic material. The outer surface may include a fused area comprising a first thermoplastic yarn. The inner surface may be at least partially formed with a second yarn and may substantially exclude the thermoplastic material. There may be a transitional area including a reduced amount of thermoplastic material relative to a fused area. The knitted component may include a cushioning material between layers of the knit element.

Abstract: A hermetically sealable millimeter waveguide launch transition feedthrough for channelling high frequency electrical signals in a circuit which includes at least one waveguide. An aperture is formed in one wall of the waveguide and a conductive pin passes through the aperture. The pin is sealed therein by a dielectric material which surrounds the pin so as to isolate it from the waveguide wall. A probe head is disposed at one end of the conductive pin and within the waveguide. The opposite end of the pin contains a second probe head or other circuit connector. The transition may be effectively implemented in waveguide-to-waveguide or waveguide-to-device applications as well as in colinear device housing applications.
