Isolation (illusion) important developments was the combination of crystal ball isolations and body-popping/locking/waving dance styles, as seen in the styles of, amongst others, Nik Robson and Matt Hennem in the '90s. Isolation (illusion) In contact juggling, poi spinning, hooping and other types of object manipulation, an isolation is an illusion whereby a prop appears to float in space, with the performer's hands and body moving around it. In reality the performer is supporting the prop, and countering his or her movement relative to the prop. Michael Moschen is originally credited for developing several of the techniques for ball isolations (as well as
Galvanic isolation preventing accidental current from reaching ground through a person's body. Transformers couple by magnetic flux. The primary and secondary windings of a transformer are not connected to each other (an autotransformer has a conductive connection between its windings and so does not provide isolation). The voltage difference that may safely be applied between windings without risk of breakdown (the isolation voltage) is specified in kilovolts by an industry standard. The same applies to transductors. While transformers are usually used to change voltages, isolation transformers with a 1:1 ratio are used in safety applications. If two electronic systems have a common
