Method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. In accordance with the noncontact optical detection embodiments, the non-contact measurement device is an optical system in which one of a coherent or noncoherent light beam is transmitted from a light source onto a surface of the ultrasonic horn, generating reflected light at a photodetector. Hair weft lengths are attached to the filament along an arcuate length of the filament. A chamber is provided in the connector housing adapted to securely retain contacts. The offset of the radial regions is configured to reduce the geometrical interference of the cam lobes across the camming range.
