Data center cooling system that prevents condensation caused by opening external access doors
An environmental system protects internal components of a data center from condensation due to exposure to outside air. An environmental controller of the environmental system monitors sensor(s) that detect an outside temperature value and an outside humidity value of the outside air and an interior air temperature value of the data center. The environmental controller identifies an external access request to open an access door that exposes heat-generating IT component(s) within the data center to outside air. Based on the outside and the interior air temperature values and the outside humidity value received from sensor(s), the environmental controller determines that a dew point temperature of the outside air is greater than the interior air temperature. In response, the environmental controller increases a temperature set point of the cooling system to a first temperature value that increases the interior air temperature above the dew point temperature of the outside air. |

This can cause the maximum (luminous) flux across a range of colors that the lighting device can render to vary greatly. For example, a white color may be rendered at a far greater intensity than a primary color. In a second operating mode the specified chromaticity is rendered based on a predetermined maximum (luminous) flux for that specified chromaticity, or a color range that it is comprised in, or a predetermined maximum (luminous) flux for one or more color channels that are used in combination to render the light effect. This reduces the differences in maximum (luminous) flux of lighting effects rendered across the range of colors that are rendered by the lighting device. |

Embodiments can establish respective multicast groups for the media channel offering in at least the first carrier and a subsequent second carrier, and can notify the craft of the multicast groups prior to the craft being serviced by the second carrier. Such pre-notification can permit multicast handover of the media channel offering from the first carrier to the second carrier in a manner that avoids typical handover-related. For example, embodiments can direct multicast delivery of the media channel offering to the craft in accordance with the first multicast group while being serviced by the first carrier and in accordance with the second multicast group while being serviced by the second. |

Methods and systems for an AC grid having increased power throughput
A method increases the power of an AC grid by means of the conductors which connect the grid coils of the grid transformer. The conductor-ground voltages and the AC phase voltage are kept lower than a voltage value. The sinusoidal phase voltages of the expanded grid are increased by up to 25% compared to the AC phase voltages, while the phase currents always remain sinusoidal. To this end, the Δ generators couple harmonic voltages between the conductors and ground and reduce the amplitude of the resulting hypersinusoidal conductor-ground voltages such that they always remain below the Uix value. In addition, the Δ generators control the transferred grid power. |
