First Claim
Patent Images
1. An impact indicator, comprising:
- a tube having a first fluid and a second fluid disposed therein, wherein a viscosity of the second fluid is greater than a viscosity of the first fluid, and wherein, responsive to a predetermined level of an acceleration event received by the impact indicator, at least a portion of the first fluid mixes into the second fluid to create a change in color of the second fluid to provide a visual indication of the received acceleration event.

Abstract
A device and technique for impact detection includes a tube having a first fluid and a second fluid disposed therein, wherein a viscosity of the second fluid is greater than a viscosity of the first fluid, and wherein, responsive to a predetermined level of impact received by the impact indicator, at least a portion of the first fluid mixes into the second fluid to create a change in color of the second fluid to provide a visual indication of the received impact.

15. An impact indicator, comprising:
-
a tube; a first fluid disposed within the tube; a second fluid disposed within the tube, and a third fluid disposed within the tube, wherein the third fluid is disposed between and separates the first fluid from the second fluid in a non-activated state of the impact indicator, and wherein, responsive to a predetermined level of impact received by the impact indicator, at least a portion of the first fluid contacts the second fluid to create a change in color of the second fluid to provide a visual indication of the received impact. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method for manufacturing an impact indicator, comprising:
-
disposing, within a tube, a first fluid; disposing, within the tube, a second fluid spaced apart from the first fluid by a third fluid, the second fluid selected having a viscosity greater than a viscosity of the first fluid, and wherein, responsive to a predetermined level of impact received by the impact indicator, at least a portion of the first fluid contacts the second fluid to create a change in color of the second fluid to provide a visual indication of the received impact. - View Dependent Claims (23, 24, 25, 26, 27)
