Shock is a vector that has units of an acceleration (rate of change of velocity). The unit g (or g) represents multiples of the standard acceleration of gravity and is conventionally used. A shock pulse can be characterised by its peak acceleration, the duration, and the shape of the shock pulse (half sine, triangular, trapezoidal, etc.).
Shock pulse method (SPM) is a technique for using signals from rotating rolling bearings as the basis for efficient condition monitoring of machines. From the innovation of the method in 1969 it has been further developed and broadened and is a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance.
A shock on a cushioned item usually has a smoother shock pulse., and thus more consistent responses from shock detector. Shocks are vector quantities with the direction of the shock being important to the item of interest, Shock detectors also can be highly sensitive to the direction of the input shock. [1] A shock detector can be evaluated:
A pulser pump makes use of water that flows through pipes and an air chamber from an upper reservoir to a lower reservoir. The intake is a trompe, which uses water flow to pump air to a separation chamber; air trapped in the chamber then drives an airlift pump. The top of the pipe that connects the upper reservoir to the air chamber is ...
The Circulation Improving Resuscitation Care (CIRC) trial is the largest prospective randomized trial to date for mechanical chest compressions in out-of-hospital cardiac arrest (OHCA). The goal was to demonstrate that the AutoPulse Non-invasive Cardiac Support Pump is a safe and effective component of a system of care focusing on high-quality ...

The spindle of the shock absorber now became the upper suspension pivot, usually double-ended. One of the last mass-production sports cars to still use lever arm shock absorbers was the MG B. [8] This had a lever arm shock absorber as the upper wishbone. A popular handling upgrade in later years was to fit telescopic shock absorbers instead.
