A method for operating a heat exchange system is provided. The heat exchange system includes at least one heat exchange chamber with heat exchange chamber boundaries which surround at least one heat exchange chamber interior of the heat exchange chamber, wherein the heat exchange chamber boundaries comprise at least one first opening for guiding in an inflow of at least one heat transfer fluid into the heat exchange chamber interior and at least one second opening for guiding out an outflow of the heat transfer fluid out of the heat exchange chamber interior, at least one heat storage material is arranged in the heat exchange chamber interior such that a heat exchange flow of the heat transfer fluid through the heat exchange chamber interior causes a heat exchange between the heat storage material and the heat transfer fluid.

An airflow sensor for a heat sink has a substantially flat base portion and a deformable upper portion electrically coupled to the base portion that contacts a conductive strip. As airflow increases, the deformable upper portion deforms and moves away from the source of airflow, which moves the point of contact between the deformable upper portion and the conductive strip farther away from the source of the airflow. The difference in the point of contact is measured, and is used to characterize the airflow sensor for different airflows. Data from the airflow sensor can then be logged during system operation. When needed, the data from the airflow sensor can be read from the log and converted to airflow using the airflow sensor characterization data. In this manner the airflow through a heat sink may be dynamically measured, allowing analysis and correlation between system events and airflow through the heat sink.

This counter-current dual-flow air/air exchanger (1) includes a first network of channels oriented along a longitudinal axis (X-X) of the exchanger (1), suitable for the circulation of a first airflow (F1) in a first direction, and a second network of channels oriented along the longitudinal axis (X-X) of the exchanger (1), suitable for the circulation of a second airflow (F2) in the direction opposite the first airflow (F1). The exchanger (1) includes members (10, 12, 14) for reversing the flow direction of the second airflow (F2) in the second network of channels, such that the first and second airflows (F1, F2) circulate co-currently, suitable for protecting the exchanger (1) from ice.

This disclosure relates to a method and a device for controlling the movement of a concrete-distributing boom, the boom base of which is mounted on a slewing gear so as to be rotatable about a vertical axis of rotation, the slewing gear being actuated by means of a rotary drive and, if necessary, a brake in order to bring the boom into a desired angular position, it being possible for an undesired natural oscillation of the boom to occur in the horizontal direction upon accelerating and/or decelerating the boom. According to this disclosure, it is proposed that the rotary drive be temporarily switched to a freewheel mode in the range of at least one peak of oscillation of the natural oscillation, so that the slewing gear is freely movable and the natural oscillation is reduced.

An apparatus with two anchors including a housing, a movable element, and a rotary element is provided. The housing includes a first expansion unit, a second expansion unit, and a linkage. First alignment structures are disposed in the movable element and anti-rotation structures are disposed in the linkage. When the movable element and the rotary element enter the housing from two ends and are coupled along an axis, the movable element and the rotary element can approach each other to expand the first expansion unit and the second expansion unit to fonn two anchors. The apparatus :with two anchors secures a sensor in a variety of environments such as walls or machines. When the apparatus with two anchors fixes a sensor in a hole of a stamping machine, the impact force does not cause stress concentration on the sensor so as to improve the reliability of the sensor.

Described herein are various technologies pertaining to predicting an amount of electrical power that is to be generated by a power system at a future point in time, wherein the power system utilizes a renewable energy resource to generate electrical power. A camera is positioned to capture an image of sky over a geographic region of interest. The image is analyzed to predict an amount of solar radiation that is to be received by the power source at a future point in time. The predicted solar radiation is used to predict an amount of electrical power that will be output by the power system at the future point in time. A computational resource of a data center that is powered by way of the power source is managed as a function of the predicted amount of power.
