Fall detection system
First Claim
1. A fall detection system comprising:
- at least one sensor configured to detect acceleration and orientation of a host;
at least one indicator device having an alarm mode; and
a controller operatively connected to the at least one sensor and the at least one indicator device, the controller programmed or configured to;
receive acceleration and orientation data generated by the at least one sensor;
compare at least a portion of the received data with at least one specified parameter indicative of a fall event; and
based on the comparison, activating or causing the activation of the at least one indicator device to enter the alarm mode,wherein the at least one specified parameter comprises at least one of the following;
an acceleration exceeding a predetermined threshold, a change between a starting orientation of the host before an acceleration event and a final orientation of the host after the acceleration event, a lack of movement of the host for a predetermined length of time after the acceleration event, or any combination thereof, andwherein the at least one sensor is positioned proximate to a center of gravity of the host to determine the orientation of the host based on an orientation of the at least one sensor.

Abstract
A fall detection system includes at least one sensor configured to detect acceleration and orientation of a host, at least one indicator device having an alarm mode, and a controller operatively connected to the at least one sensor and the at least one indicator device. The controller is programmed to receive data generated by the at least one sensor, compare at least a portion of the received data with at least one specified parameter indicative of a fall event, and, based on the comparison, activating the at least one indicator device to enter the alarm mode. The at least one specified parameter includes at least one of the following: an acceleration exceeding a predetermined threshold, a change between a starting and a final orientation of the host before and after an acceleration event, a lack of movement of the host for a predetermined time after the acceleration event, or any combination thereof.

14. A self-contained breathing apparatus (SCBA) comprising:
-
a tank mounted on a rigid frame configured for mounting on a user'"'"'s back using one or more straps; and a fall detection system comprising; at least one sensor connected to the rigid frame to detect acceleration and orientation of the user wearing the rigid frame; at least one indicator device having an alarm mode; and a controller operatively connected to the at least one sensor and the at least one indicator device, the controller programmed or configured to receive acceleration and orientation data generated by the at least one sensor, compare at least a portion of the received data with at least one specified parameter indicative of a fall event, and, based on the comparison, activate or cause the activation of the at least one indicator device to enter the alarm mode, wherein the at least one specified parameter comprises at least one of the following;
an acceleration exceeding a predetermined threshold, a change between a starting orientation of the host before an acceleration event and a final orientation of the host after the acceleration event, a lack of movement of the host for a predetermined length of time after the acceleration event, or any combination thereof, andwherein the rigid frame and the at least one sensor are positioned proximate to a center of gravity of the user to determine the orientation of the user based on an orientation of the at least one sensor. - View Dependent Claims (15, 16, 17, 18, 19, 20)
