A method for controlling an item of electrical equipment of a motor vehicle including a device for controlling the item of equipment including a microcontroller, which is configured to generate an AC electrical signal for controlling the item of equipment characterized by its duty cycle, and a driver interface that is characterized by a maximum operating temperature threshold beyond which the driver interface is inoperative. The method includes determining the internal temperature of the driver interface, comparing the determined internal temperature with a first predetermined warning threshold and decreasing the duty cycle of the electrical signal when the first warning threshold has been exceeded so as to limit the power of the electrical signal and thus to keep the internal temperature of the driver interface below its maximum operating temperature threshold.

The present invention relates to systems and methods for improved building systems management and maintenance. The present invention provides a system for providing an augmented reality-like interface for the management and maintenance of building systems, specifically the mechanical, electrical, and plumbing (MEP) systems within a building, including the heating, ventilation, and air-conditioning (HVAC) systems.

A combined cooling and heating system including a district cooling grid having a feed conduit for an incoming flow of cooling fluid having a first temperature, and a return conduit for a return flow of cooling fluid having a second temperature, the second temperature being higher than the first temperature; a local cooling system being configured to absorb heat from a first building and comprising a heat exchanger having a heat exchanger inlet and a heat exchanger outlet; and a local heating system being configured to heat the first or a second building and comprising a heat pump having a heat pump inlet and a heat pump outlet. The heat exchanger inlet is connected to the feed conduit of the district cooling grid; and the heat pump inlet is connected to the return conduit of the district cooling grid and to the heat exchanger outlet.

A thermostat device may use one or two temperature sensors inside the housing of the thermostat device to perform temperature compensation to determine the ambient temperature outside the housing of the thermostat device. Processing circuitry of the thermostat device may determine a current operating mode of the thermostat device out of a plurality of operating modes. The processing circuitry may also use machine learning to estimate the current and voltage of the thermostat device based on temperature differences between the two temperature sensors. The processing circuitry may determine, based at least in part on the estimated current and voltage of the thermostat device and the current operating mode of the thermostat device, an ambient temperature outside the housing of the thermostat device.

A warm-up evaluation device includes: a temperature data acquisition unit that acquires temperature data before warm-up operation when a machine performs the warm-up operation; a parameter value acquisition unit that acquires parameter values set in a program for performing the warm-up operation; an evaluation data acquisition unit that acquires evaluation data for evaluating a result of the warm-up operation; a learning unit that learns a machine learning model which receives the temperature data and the parameter values as an input and outputs the evaluation data on the basis of a plurality of warm-up operations performed by the same or the same types of machines; and an evaluation unit that inputs candidates for the parameter values to the machine learning model together with the temperature data and outputs the evaluation data when the same or the same types of machines perform a new warm-up operation.

A demand response system includes a mobile application of a mobile device that is configured to initiate altering an operating condition of a network device disposed at a site using location based services. A demand response application interface module is configured to enable access between a utility company and the network device to communicate energy management information therebetween. The network device is configured to be remotely altered by each of the demand response application interface module and the mobile application separately based on the location based services and the energy management information. A method of managing a demand response system includes detecting a user being disposed away from a site, detecting energy management information from a utility company associated with the site, and initiating a reduction in energy use at the site in response to the relative location of the user and the energy management information.

A tool for providing a visualization of a system may reveal an interactive navigation environment for building performance observation and assessment. The tool may be associated with a processor. The environment may incorporate a treemap, a graph pane, a treemap filter, a graph pane selector, a selected units box and a date/time control mechanism. A visualization of the environment, among other things, may be presented on a display. The treemap may exhibit a building geometry and/or equipment units hierarchically, along with some data information. Units may be interactively selected from the treemap and placed in the box for analysis. The graph pane may show a configuration and display of unit analysis. Selection of detailed views for units in the box may be provided by the graph pane selector. Date and time intervals for analysis may be selected by the control mechanism.

A method for regulating a volume flow rate, and a test stand with a liquid circuit for carrying out the method is provided. A pump and a flow control valve are connected in series in the liquid circuit, and the orifice width of the flow control valve is set as a function of a setpoint value of the volume flow rate of the liquid, in order to specify, on the basis of the orifice width, a characteristic curve of the pump that plots the volume flow rate over the differential pressure. Once a characteristic curve has been specified, the differential pressure of the pump is set such that the volume flow rate corresponds to the setpoint value of the volume flow rate.

An arrangement for monitoring an aseptic manufacturing process includes product condition sensors capable of making closely spaced measurements of a product condition such as temperature or humidity. The measurements are made using closely spaced sensors arranged in a linear array on a single probe, which may be used to take measurements at multiple levels within the product. Data from the sensors is transmitted to a data collection point via short range wireless digital communications. The sensors may be used to measure temperature and humidity at a single point. For example, when the sensors are used in pharmaceutical freeze drying, the location of a sublimation front may be calculated for each vial, and the freeze drying process may be controlled using the data.

A cloud server (104) receives environmental information of respective installation sites of a plurality of appliances (101a, 101b, 101c, 102a, 102b) via a network (1000), and determines one or more appliances that are installed in a same room among the plurality of appliances (101a, 101b, 101c, 102a, 102b), based on the received environmental information.
