Abstract: A power splitter that amplifies an input radio-frequency (RF) signal. The power splitter uses a single transistor in a common emitter stage of a cascode amplifier and two or more common base stages of the cascode amplifier to amplify and to split the input RF signal. A common base biasing signal can be used to simultaneously enable two or more of the common base stages to generate two or more amplified RF output signals.

Abstract: A heating ventilation and air conditioning (HVAC) system may effectively provide and/or substantially maintain adjacent thermal zones that have different temperatures and/or humidities from one another. The HVAC system may include a duct network including zonal ducts each having a zonal duct exit configured to create aerodynamic profiles that result in a thermal zone. A thermal zone may be characterized by a volume having a temperature and/or humidity which may differ from an adjacent thermal zone, such that a temperature and/or humidity gradient exists at a thermal zone boundary between adjacent thermal zones, and such that diffusion of the temperature and/or humidity between the adjacent thermal zones is aerodynamically inhibited, or otherwise minimized.

Abstract: An array of membranes comprising amphipathic molecules is formed using an apparatus comprising a support defining an array of compartments. Volumes comprising polar medium are provided within respective compartments and a layer comprising apolar medium is provided extending across the openings with the volumes. Polar medium is flowed across the support to displace apolar medium and form a layer in contact with the volumes, forming membranes comprising amphipathic molecules at the interfaces. In one construction of the apparatus, the support that comprises partitions which comprise inner portions and outer portions. The inner portions define inner recesses without gaps therebetween that are capable of constraining the volumes comprising polar medium contained in neighbouring inner recesses from contacting each other. The outer portions extend outwardly from the inner portions and have gaps allowing the flow of an apolar medium across the substrate.
