Abstract: Eine Gassensor-Einheit beinhaltet ein dielektrisches Substrat, eine Heizvorrichtung, die in eine erste Seite des Substrats integriert ist, sowie ein isolierendes Dielektrikum, das über der Heizvorrichtung ausgebildet ist. Eine Gassensor-Schicht ist auf einer zweiten Seite des Substrats ausgebildet, die entgegengesetzt zu der ersten Seite liegt. Auf dem Gassensor-Substrat sind Kontakte ausgebildet. Auf einem Bereich der Gassensor-Schicht zwischen den Kontakten ist ein Edelmaterial ausgebildet, das als ein ionisierender Katalysator wirkt, so dass eine Adsorption eines spezifischen Gases bei Erwärmen auf eine Temperatur elektronische Eigenschaften der Gassensor-Schicht verändert, um so eine Erfassung des Gases zu erlauben.

Abstract: An irrigation system is provided and includes a main irrigation line, one or more lateral driplines, each lateral dripline being divided into zones and including a plurality of emitters at each zone and a plurality of controllable valves disposed along each of the one or more lateral driplines at zone borders. Each one of the plurality of controllable valves is actuatable to activate corresponding emitters in the associated zone in a zone by zone cycle and each one of the plurality of emitters is replaceable to vary an amount of deliverable fluid by the zone by zone cycle.

Abstract: Techniques for using air flow analysis to model thermal zones are provided. In one aspect, a method for modeling thermal zones in a space, e.g., in a data center, includes the following steps. A graphical representation of the space is provided. At least one domain is defined in the space for modeling. A mesh is created in the domain by sub-dividing the domain into a set of discrete sub-domains that interconnect a plurality of nodes. Air flow sources and sinks are identified in the domain. Air flow measurements are obtained from one or more of the air flow sources and sinks. An air flow velocity vector at a center of each sub- domain is determined using the air flow measurements obtained from the air flow sources and sinks. Each velocity vector is traced to one of the air flow sources, wherein a combination of the traces to a given one of the air flow sources represents a thermal zone in the space.

Abstract: Energy-efficient data center cooling techniques that utilize free cooling and/or solar cooling are provided. In one aspect, a cooling system is provided including a cooling tower; one or more modular refrigeration chiller units; and a water loop that can be selectively directed through the cooling tower, through one or more of the modular refrigeration chiller units or through a combination thereof. Another cooling system is provided including a solar cooling unit; one or more modular refrigeration chiller units; and a water loop that can be selectively directed through the solar cooling unit, through one or more of the modular refrigeration chiller units or through a combination thereof.
