Abstract: An aircraft includes external structures, and one or more thermal emitters integrated with one or more of the external structures. The one or more thermal emitters are configured to generate heat to deice the one or more external structures. The one or more thermal emitters are configured to receive electrical power from one or more of an auxiliary power unit of the aircraft, a power distribution system of the aircraft, one or more engines of the aircraft, or an external power cart that is separate and distinct from the aircraft.

Abstract: A liquid flow distribution system comprises a flow chamber and a rotor. The flow chamber has a flow chamber inlet, a flow chamber outlet and a chamber flow path extending from the flow chamber inlet to the flow chamber outlet. The flow chamber path is curved so as to generate a generally vortical flow in liquid passing through the chamber flow path. The rotor has a plurality of rotor blades rotatably mounted about a rotor axis. The rotor is mounted in proximity to the flow chamber outlet and positioned such that a flow of liquid exiting the flow chamber outlet impacts one or more of the rotor blades to rotationally drive the rotor. Rotational driving of the rotor in turn disperses liquid impacting the rotor blades.

Abstract: A water treatment unit has a support housing vertically extending between a support housing upper end and a support housing lower end. The support housing includes a pair of opposing primary housing walls and a pair of opposing secondary housing walls. Each of the secondary housing walls is formed separately from, and mechanically joined to, each of the primary housing walls. Each of the primary housing walls is perforated to allow airflow in a first direction laterally through a treatment cavity defined by the housing walls. A plurality of hangers extend in the first direction between the primary housing walls and are supported by the support housing. The hangers are mutually spaced between the secondary housing walls across the treatment cavity (23). A plurality of biotreatment membranes each carry a biomass culture and are draped over, and supported by, one of the hangers to define two opposing membrane walls each extending downwardly from the hanger.

Abstract: Apparatus for monitoring a fetal heart-beat is able to extract one or more fetal electrocardiograms (fECGs) from a composite signal detected at the abdomen of a pregnant woman. The apparatus includes specific low-noise components: a plurality of low-noise electrodes (1-3, R) for placement on the abdomen during pregnancy and a low-noise signal recording and processing means (34). Screened leads are also used, as required. Signals indicative of voltages developed between each abdominal electrode (1-3) and a reference electrode (R) are recorded in a plurality of signal channels. Data within each channel is digitised and processed in order to generate a plurality of separated source signals, at least one of which relates to the fECG of a single fetus. Single-channel fECGs may be reconstructed using the source signals identified as belonging to the same fetus.
