Abstract: An oil management controller for heating, ventilation, or air conditioning (HVAC) equipment. The controller includes a processing circuit. The processing circuit is configured to analyze operating data for the HVAC equipment using a machine learning model to predict a variable state or condition of oil used by the HVAC equipment. The processing circuit is configured to identify an oil deficiency based on the variable state or condition of the oil. The processing circuit is configured to automatically initiate a corrective action responsive to identifying the oil deficiency.

Abstract: An environmental control system of a building including a first building device operable to affect environmental conditions of a zone of the building by providing a first input to the zone. The system includes a second building device operable to independently affect a subset of the environmental conditions by providing a second input to the zone and further includes a controller including a processing circuit. The processing circuit is configured to perform an optimization to generate control decisions for the building devices. The optimization is performed subject to constraints for the environmental conditions and uses a predictive model that predicts an effect of the control decisions on the environmental conditions. The processing circuit is configured to operate the building devices in accordance with the control decisions.

Abstract: The present invention provides a mechanical extending linkage configured to be mounted in a seating unit capable of being movable between a retracted position and an extended position and comprising a seat, a backrest and extendable primary and secondary footrests. The mechanical extending linkage comprises a footrest assembly for extending and retracting the primary footrest and the secondary footrest, the footrest assembly comprising a primary footrest link, a secondary footrest link, and an intermediate link set having a first intermediate link, a second intermediate link, a third intermediate link and a fourth intermediate link; the footrest assembly is configured in such a manner that the secondary footrest link, the first intermediate link and the second intermediate link are arranged substantially parallel with the seat when the seating unit is in the retracted position. The present invention further provides a seating unit comprising the mechanical extending linkages.

Abstract: A sofa (1) having adjustable backrest position, and including a seat frame (10), a backrest frame (20), a guide-rail frame (30) and a driving device (40); the guide-rail frame (30) includes a guide-rail (300) which is fixedly connected to the seat frame (10) and which extends in the front-back direction of the sofa (1); a first end of a support frame (50) is connected to the backrest frame (20); a second end of the support frame (50) is connected to the guide-rail (300) so as to be able so slide relative thereto; the driving device (40) is arranged so as to be linked-motion connected to the support frame (50) in order to lead the second end of the support frame (50) to slide relative to the guide-rail (300).

Abstract: Methods and apparatus for controlling microloading, such as within cell microloading between adjacent cells or isolated/dense microloading between areas of isolated or dense features during shallow trench isolation (STI) fabrication processes, or other trench fabrication processes, are provided herein. In some embodiments, a method for fabricating STI structures may include providing a substrate having a patterned mask layer formed thereon corresponding to one or more STI structures to be etched; etching the substrate through the patterned mask layer using a plasma formed from a process gas to form one or more STI structure recesses on the substrate; and pulsing the plasma for at least a portion of etching the substrate to control at least one of a depth or width of the one or more STI structure recesses.
