Microscale acceleration history discriminators

Title: Microscale acceleration history discriminators

Full Record
Other Related Research

Abstract

A new class of micromechanical acceleration history discriminators is claimed. These discriminators allow the precise differentiation of a wide range of acceleration-time histories, thereby allowing adaptive events to be triggered in response to the severity (or lack thereof) of an external environment. Such devices have applications in airbag activation, and other safety and surety applications.
