Enhanced Piezoelectric Shunt Design

open access: yesShock and Vibration, 2003
Piezoceramic material connected to an electronic shunt branch circuit has formed a successful vibration reduction device. One drawback of the conventional electronic shunt circuit is the large inductance required when suppressing low frequency vibration ...

Parents' management of their child's hydrocephalus and shunt [PDF]

open access: yes, 2010
Introduction Shunts are the main treatment for hydrocephalus. When shunts malfunction the consequences are serious and can be life threatening. Identifying shunt malfunction requires effective parent-professional collaboration: parents need to recognise
