Abstract: A system for monitoring compressed fluid sources of an evacuation assembly may comprise a controller and a tangible, non-transitory memory configured to communicate with the controller. The controller may perform operations, which may comprise receiving a series of first pressure measurements from a first sensor system, receiving a series of second pressure measurements from a second sensor system, calculating a first pressure trend using the series of first pressure measurements, calculating a second pressure trend using the series of second pressure measurements, and comparing each of the first pressure trend and the second pressure trend to a threshold pressure trend.

Abstract: A gauge device is provided and includes an analog display to signify a measured valued, a motor and worm gear arrangement which is configured to retain a current state of the analog display when de-energized or to change the analog display when energized and a control system. The control system is configured to normally de-energize the motor and worm gear arrangement and to energize the motor and worm gear arrangement only in accordance with a calculated state of the analog display differing from the current state by at least a threshold level.

Abstract: Embodiments include techniques for efficient energy management for wireless pressure indication systems, the techniques include transmitting, via a wireless pressure sensor (WPS) device, an awake message at a configurable interval, and responsive to receiving a reply message to the awake message, entering an active state. The techniques also include sensing a present condition to obtain sensor information, transmitting the sensor information, and responsive to receiving an acknowledgment message for the sensor information, returning to a sleep state.
