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
Isolation transformer no conductive connection between transformer secondary and earth, there is no danger in touching a live part of the circuit while another part of the body is earthed. Electrical isolation is considered to be particularly important on medical equipment, and special standards apply. Often the system must additionally be designed so that fault conditions do not interrupt power, but generate a warning. Isolation transformers are also used for the power supply of devices not at ground potential. An example is the Austin transformer for the power supply of air-traffic obstacle warning lamps on radio antenna masts. Without the isolation transformer,
