Abstract

According to one aspect of the present disclosure, a device and technique for tilt detection and indication is disclosed. The tilt indicator includes a first member having a reservoir for retaining a granular indicating media therein; and a second member coupled to the first member and having an adhesive portion located corresponding to an indicating area of the first member. Responsive to a tilt event, at least a portion of the indicating media exits the reservoir and travels to the indicating area where the adhesive portion retains at least a portion of the indicating media within the indicating area. A blocking element located within a buffering area located between the reservoir and the indicating area is configured to impede travel of the indicating media from the reservoir toward the indicating area when the tilt indicator is in an activated state.

Claims (30)

1. A tilt indicator, comprising:

a first member having a reservoir for retaining a granular indicating media therein, an indicating area, a buffering area located between the reservoir and the indicating area, and a blocking element located within the buffering area, the blocking element configured to impede travel of the indicating media from the reservoir toward the indicating area when the tilt indicator is in an activated state; and

a second member coupled to the first member and having an adhesive portion located corresponding to the indicating area of the first member; and

wherein, responsive to a tilt event, at least a portion of the indicating media exits the reservoir and travels to the indicating area, the adhesive portion retaining at least a portion of the indicating media within the indicating area.

2. The tilt indicator of claim 1 , wherein the indicating media comprises crushed quartz.

3. The tilt indicator of claim 1 , further comprising a narrowed passageway extending between the reservoir and the buffering area.

4. The tilt indicator of claim 3 , further comprising an arming plug blocking the passageway and retaining the indicating media within the reservoir in a pre-activated state of the tilt indicator, the arming plug removable to place the tilt indicator in the activated state.

5. The tilt indicator of claim 1 , wherein the indicating area comprises a first indicating area spaced apart from a second indicating area, the first indicating area located in an elevated vertical position relative to the second indicating area.

6. The tilt indicator of claim 1 , wherein the blocking element comprises a first blocking element and a second blocking element, the first blocking element having a first end located proximate the reservoir and a second end located proximate the indicating area, and wherein the second blocking element extends over the second end of the first blocking element.

7. The tilt indicator of claim 1 , wherein the indicating area comprises a first indicating area for visually indicating a tilt event in a first direction and a second indicating area for visually indicating a tilt event in a second direction.

8. A tilt indicator, comprising:

a first member coupled to a second member and forming a cavity therebetween, the cavity including a reservoir for retaining a granular indicating media therein, an indicating area spaced apart from the reservoir by a buffering area, and a blocking element located within the buffering area configured to impede travel of the indicating media from the reservoir to the indicating area when the tilt indicator is in an activated state; and

an adhesive layer disposed on at least one of the first and second members in an area corresponding to the indicating area; and

wherein, responsive to a tilt event, at least a portion of the indicating media exits the reservoir and travels to the indicating area, the adhesive layer retaining at least a portion of the indicating media within the indicating area.

9. The tilt indicator of claim 8 , wherein, responsive to an acceleration event in a lateral or vertical direction causing the indicating media to exit the reservoir, the blocking element is configured to impede movement of the indicating media into the indicating area.

10. The tilt indicator of claim 8 , wherein the indicating media comprises crushed quartz.

11. The tilt indicator of claim 8 , wherein the indicating area comprises a first indicating area for visually indicating a tilt event in a first direction and a second indicating area for visually indicating a tilt event in a second direction.

12. The tilt indicator of claim 11 , wherein the first indicating area is located in an elevated vertical position relative to the second indicating area.

13. A tilt indicator, comprising:

a base assembly formed having an internal cavity, the cavity including:

a reservoir for holding a granular indicating media therein;

an indicating area spaced apart from the reservoir by a buffering area; and

a blocking element located within the buffering area and configured to impede travel of the indicating media from the reservoir to the indicating area when the tilt indicator is in an activated state; and

wherein the base assembly further comprises a retention element located proximate to the indicating area; and

wherein, responsive to tilting of the tilt indicator from a first orientation to a second orientation, at least a portion of the indicating media exits the reservoir and travels to the indicating area, the retention element retaining at least a portion of the indicating media within the indicating area in response to the tilt indicator returning to the first orientation from the second orientation.

14. The tilt indicator of claim 13 , wherein the blocking element is configured to cause turbulence in a flow of the indicating media exiting the reservoir in response to an acceleration event.

15. The tilt indicator of claim 13 , wherein the blocking element is configured to reduce a speed of travel of the indicating media within the buffering area in response to an acceleration event.

16. The tilt indicator of claim 13 , wherein the indicating media comprises crushed quartz.

17. The tilt indicator of claim 13 , further comprising an arming plug for retaining the indicating media within the reservoir in a pre-activated state of the tilt indicator, the arming plug removable to place the tilt indicator into the activated state.

18. The tilt indicator of claim 13 , wherein the blocking element comprises a first blocking element extending over an end of a second blocking element.
