A system applies cardiopulmonary resuscitation (CPR) to a recipient. An automated controller is provided together with a compression device which periodically applies a force to a recipient's thorax under control of the automated controller. A band is adapted to be placed around a portion of the torso of the recipient corresponding to the recipient's thorax. A driver mechanism shortens and lengthens the circumference of the band. By shortening the circumference of the band, radial forces are created acting on at least lateral and anterior portions of the thorax. A translating mechanism may be. provided for translating the radial forces to increase the concentration of anterior radial forces acting on the anterior portion of the thorax. The driver mechanism may comprise a tension device for applying a circumference tensile force to the band. The driver mechanism may comprise an electric motor, a pneumatic linear actuator, or a contracting mechanism defining certain portions of the circumference of the band. The contracting mechanism may comprise plural fluid-receiving cells linked together along the circumference of the band. The width of each of the fluid-receiving cells becomes smaller as each cell is filled with a fluid. This causes the contraction of the band and a resulting shortening of the circumference of the band.

A transfer gate or pass gate circuit for transferring logic signals between nodes for a range of available high-potential supply levels. The primary transfer gate is designed to protect against potentials that either exceed either a high-potential or a low-potential level or that undershoot such potential levels. For overshoot (overvoltage) tolerance, this is achieved by coupling a NMOS transistor in parallel with a pair of PMOS transistors that are coupled in series. All three transistors are located between two nodes, either of which can be the input or the output of the transfer gate. The NMOS transistor is designed to be larger than the PMOS transistors and carries most of the transfer capability. The smaller PMOS transistors are designed to eliminate potential drops that would otherwise occur with a single NMOS transistor or with a complementary pair of transistors. For undershoot (undervoltage) tolerance, a PMOS transistor is coupled in parallel with a pair of NMOS transistors that are coupled in series.
