Abstract: Disclosed herein is a console comprising: at least one air inlet; a first receptacle configured to host a first source of nitric oxide; a second receptacle configured to host a second source of nitric oxide; a controller configured to selectively couple the at least one air inlet to one of the first receptacle or the second receptacle to deliver the nitric oxide from the first or the second source; and an outlet coupled to the first and/or second receptacle and configured to deliver nitric oxide to a subject.

Abstract: A road paver comprises a tractor vehicle with a material hopper for receiving paving material and a paving screed for compacting paving material. The paving screed comprises at least one electric heating device for heating the paving screed. The road paver comprises at least one electric switching assembly configured to switch an electric power supply of the electric heating device. The electric switching assembly comprises an electric parallel circuit of two switching devices, wherein the electric parallel circuit of the two switching devices forms a series electric circuit with the electric heating device.

Abstract: An electrical characteristic of a privacy glazing structure and indicative of a health of the privacy glazing structure can be measured at a first time and at a second time later than the first time. In response to detecting a change in the electrical characteristic indicating a change in the health of the privacy glazing structure, one or more parameters of an electrical drive signal can be adjusted to compensate for the change in the health of the privacy glazing structure. The electrical characteristic can be measured at a plurality of times after the second time and compared to the electrical characteristic measured at the first time. If, at any of the plurality of times, the measured electrical characteristic differs from the electrical characteristic measured at the first time by more than a threshold amount, one or more parameters of the electrical drive signal can be adjusted.

Abstract: A heating cable for use with alternating current (AC) may include multiple conductive metal strands. A strain-relief yarn may also be included. The strands may be coated with an electrically-insulating coating. The strands, including the strain-relief yarn, may be twisted together and coated with an electrically-insulating outer coating to provide the heating cable.

Abstract: An electrical response of a privacy glazing structure to an applied electrical sensing pulse can be measured, and one or more parameters of the privacy glazing structure can be characterized. The one or more parameters can be used to load one or more drive parameters for subsequent use in an electrical drive signal used to operate the privacy glazing structure. If an electrical drive signal is already in place, the characterized one or more parameters can be compared to one or more parameters characterized at a previous time. If the one or more characterized parameters are different from those characterized at the previous time by more than a threshold amount, one or more drive parameters of the electrical drive signal can be adjusted to a new value.

Abstract: A driver for an electrically dynamic structure may store and release energy during polarity cycling to improve the energy efficiency of operation. In some examples, the driver includes an energy storage element. In operation, the driver can charge an electrically controllable optically active material to a first operating voltage at a first polarity and subsequently discharge the optically active material during polarity reversal. The driver may store energy released from the optically active material during discharging and subsequently release the energy to charge the optically active material to a second operating voltage at a second polarity different than the first polarity.
