Abstract: A controller for controlling a machine tool calculates a variation of a cutting load based on a changed rotational speed or feed rate of a tool in a machining program for machining a workpiece when the rotational speed or the feed rate is changed, and executes the machining program if the changed rotational speed and/or feed rate of the tool and/or the cutting load are within the ranges of predetermined upper and lower limit values.

Abstract: An electric water heater that includes a thermostat is retrofitted for remote control as follows. A relay is installed on an electrical feed to the electric water heater. Water temperature and electric current or power through the electrical feed are measured over time with the relay closed, and the thermostat deadband maximum and minimum are detected as the water temperature at which the thermostat turns the heating element off, and the water temperature at which the thermostat turns the heating element on, respectively. The detected thermostat deadband maximum and minimum are stored as load controller deadband maximum and minimum, respectively. The thermostat set point is raised, and the electric water heater is thereafter controlled using the load controller by operations including closing the relay when the water temperature falls below the load controller deadband minimum and opening the relay when the water temperature rises above the load controller deadband maximum.

Abstract: A method for real-time temperature management is described. In one embodiment, the method includes configuring a setting to trigger a thermal sensor to capture a thermal image of an area inside a premises and capturing, via the thermal sensor, a first thermal image of the area of the premises. In some embodiments, upon detecting the trigger, the method includes capturing, via the thermal sensor, a second thermal image of the area of the premises and identifying a thermal exchange in the area of the premises by comparing the first thermal image with the second thermal image.

Abstract: A target generating unit outputs a target value signal of a control target, and a position encoding processing unit outputs a position detection signal of the control target. A PID compensator calculates a control amount for causing the control target to follow a target position based on a difference signal between the target value signal and the position detection signal, and outputs it to an adding unit. A disturbance estimation observer outputs the result of estimation of disturbance to the adding unit. The adding unit adds the control amount output of the PID compensator to the output of the disturbance estimation observer to calculate a total control amount.

Abstract: In a control system, when a sensor receives a sensing signal, the sensor sends a notice signal to a preparatory starting device so that the preparatory starting device performs a starting operation. After the starting operation is finished, the preparatory starting device sends an operation command and/or operation power to a starting unit. The starting unit would not pass the operation command and/or the operation power to a receiving end until receiving a control signal.

Abstract: A control system (300) allows recognized standard premise electrical outlets, for example NEMA, CEE and BS, among others to be remotely monitored and/or controlled, for example, to intelligently execute blackouts or brownouts or to otherwise remotely control electrical devices. The system (300) includes a number of smart receptacles (302) that communicate with a local controller (304), e.g., via power lines using the TCP/IP protocol. The local controller (304), in turn, communicates with a remote controller (308) via the internet.

Abstract: A Manufacturing Execution System (MES) is provided that leverages industry-specific workflows to process business requests. The MES system can maintain activity sets representing industry-specific workflows that can be selected and executed in order to satisfy business-driven goals. The activity sets can comprise both business-level and control-level operations, and can be configured using an intuitive graphical interface that mitigates the need for low-level programming by the end user. Some features of the MES system are enabled or disabled based on data type compatibility with devices in communication with the MES system.

Abstract: A building has climate control equipment which controls a temperature at different locations. Different locations may be in different control zones controlled by different control devices. An occupant of a location submits a desired location temperature through a user interface on a computing device to a networked server. Setting of a desired temperature is constrained by energy saving policies and by conditions of surrounding locations. An arbitrator device determines based on constraints a new temperature setting. The new temperature setting is accompanied by an energy saving feedback. The occupants confirms the new setting. A climate control device is instructed to apply a device setting to achieve the new temperature. A climate profile of the occupant is learned from previous temperature settings by the occupant.

The control unit closes the opening-closing portion when a first assumed value of power consumed by the fan is smaller than a current value of the power. The control unit opens the opening-closing portion when a second assumed value of the power consumed by the fan is smaller than the current value of the power.

Abstract: A method keeps a synchronous machine in a stable operating zone during large transient voltage excursions on a power grid to which the machine is connected. The machine's load angle, i.e., the position of the rotor flux with respect to the position of the stator flux, is calculated. If the load angle is not within a defined range of reference values for stable machine operation, the machine's field excitation is adjusted to bring the machine's load angle within the defined range of reference values for stable machine operation.
