Abstract: Methods and apparatus monitor health by detection of sleep stage. For example, a sleep stage monitor (100) may access sensor data signals related to bodily movement and/or respiration movements. At least a portion of the detected signals may be analyzed to calculate respiration variability. The respiration variability may include one or more of variability of respiration rate and variability of respiration amplitude. A processor may then determine a sleep stage based on one or more of respiration variability and bodily movement, such as with a combination of both. The determination of sleep stages may distinguish between deep sleep and other stages of sleep, or may differentiate between deep sleep, light sleep and REM sleep. The bodily movement and respiration movement signals may be derived from one or more sensors, such as non-invasive sensor (e.g., a non-contact radio-frequency motion sensor or a pressure sensitive mattress).

Abstract: A fuel tank inerting system for an aircraft, the system comprising: a fuel tank, and a catalytic heat exchanger. The catalytic heat exchanger comprises a first flow path and a second flow path for heat exchange with the first flow path, as well as a first inlet arranged upstream of the first flow path of the catalytic heat exchanger for providing a mixture of fuel vapour and oxygen to the first flow path for sustaining a catalysed reaction, and a second inlet arranged upstream of the second flow path for providing a flow of fuel from the fuel tank to the second flow path of the catalytic heat exchanger for exchanging heat with the first flow path. The system further comprises a transfer pipe in heat exchange with the fuel tank, wherein the transfer pipe is arranged to receive fuel from the second flow path of the catalytic heat exchanger.

Abstract: The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

Abstract: A method for thermographic analysis of a heat exchanger comprises: applying vibrations to the heat exchanger as a part of a vibration testing process; capturing a thermographic image of at least a portion of the heat exchanger whilst the heat exchanger is undergoing vibrations; analysing the thermographic image; and determining a status of the heat exchanger based on the analysis of the image.

Abstract: A processing system includes methods to promote sleep. The system may include a monitor such as a non-contact motion sensor from which sleep information may be determined. User sleep information, such as sleep stages, hypnograms, sleep scores, mind recharge scores and body scores, may be recorded, evaluated and/or displayed for a user. The system may further monitor ambient and/or environmental conditions corresponding to sleep sessions. Sleep advice may be generated based on the sleep information, user queries and/or environmental conditions from one or more sleep sessions. Communicated sleep advice may include content to promote good sleep habits and/or detect risky sleep conditions. In some versions of the system, any one or more of a bedside unit 3000 sensor module, a smart processing device, such as a smart phone or smart device 3002, and network servers may be implemented to perform the methodologies of the system.
