Abstract: A system may include an air treatment assembly configured to deliver treated air to an enclosed space within a vehicle, at least one upstream sensor upstream from the air treatment assembly, and at least one downstream sensor downstream from the air treatment assembly. The upstream sensor(s) and the downstream sensor(s) are configured to detect at least one attribute of air, such as air pressure. An air treatment monitoring system is in communication with the sensors. The air treatment monitoring system receives one or more sensor signals from the sensors, and calculates an attribute differential (such as a pressure differential) based on the one or more signals.

Abstract: A method and apparatus for managing health of a motor in an aircraft is presented. A first group of motor parameters and a second group of external bias parameters in sensor data received from a sensor system associated with the aircraft in which the first group of motor parameters is for an environment affected by operation of the motor in the aircraft and the second group of external bias parameters modifies an effect of the first motor group of motor parameters in identifying a health of the motor is monitored. The health of the motor is identified based on the first group of motor parameters and the second group of external bias parameters. An action is performed based on the health of the motor identified, wherein a controller enables increasing a confidence level in indicating the health of the motor.

Abstract: A data acquisition node for coupling to a system of a vehicle includes a processor coupled to a communication interface. The processor is configured to transition from a sleep mode to a start-up detect mode after an imminent-event message is received at the communication interface. The communication interface is substantially deactivated while in the start-up detect mode. The processor also is configured to monitor sensor data from at least one sensor while in the start-up detect mode. The at least one sensor is operable to generate a signal that is representative of a physical characteristic of the system.

Abstract: Method and apparatus for determining a probability of below-specified performance of a low temperature limit control valve. During operation of an environmental control system (ECS) for a vehicle, current operation parameters related to the ECS are sensed. Historical operation parameters related to the ECS are retrieved. A probability of below-specified performance of the low temperature limit control valve is determined based on a predetermined relationship between the stored current operation parameters, the historical operation parameters, and the probability of below-specified performance of the low temperature limit valve.
