  • Patent number: 10413950
    Abstract: As sections of a rolled product (1) pass through a cooling path (2), they are initially cooled in a first cooling phase by front cooling devices (6). The sections are then not cooled in a subsequent second cooling phase. They are finally cooled again in a subsequent third cooling phase, by rear cooling devices (8) of the cooling path (2). A control device (10) of the cooling path receives in each case an initial energy value (EA) exhibited by the sections before they pass through the cooling path (2). The control device furthermore receives a target energy (E1*) and a target enthalpy (E2*). The control device (10) determines a first target cooling medium profile (K1*) on the basis of the initial energy value (EA) and the target energy (E1*). The control device controls the front cooling devices (6) in accordance with the first target cooling medium profile (K1*) while the respective section is passing through the front cooling devices (6).

    Abstract: A system that includes a temperature-controlled device, a primary energy source that is adapted to supply primary energy to the temperature-controlled device, a secondary energy source that is adapted to supply secondary energy to the temperature-controlled device, a switching device, and a measuring device. The secondary energy includes a voltage that is different than a voltage of the primary energy. The secondary energy source is adapted to supply the secondary energy to the temperature-controlled device when the temperature-controlled device is turned ON. After the measuring device measures a predetermined condition of the temperature-controlled device, the switching device is adapted to switch the system such that the primary energy source supplies the primary energy to the temperature-controlled device so that the temperature of the temperature-controlled device is generally maintained at a pre-set temperature or at a user selected temperature.

  • Patent number: 9632464
    Abstract: In an image forming apparatus according to the present invention, when an image forming operation is started from a standby state, electric power is supplied to a heater by switching to a first fixing control to turn on and off the heater to heat a heating roller with a fixed duty ratio based on the detected temperature of the heating roller, and thereafter, when detecting a state that the falling detected temperature reaches a lower limit value at which the detected temperature turns to rising, electric power is supplied to the heater by switching to a second fixing control which changes a duty ratio in accordance with a temperature difference between the detected temperature and a target control temperature.

  • Patent number: 9587604
    Abstract: A method for controlling electrical power applied to a fuel heater includes applying power to the heater, determining a value for an electrical parameter that varies as a function of the temperature of the heater, and determining a value representative of the time rate of change of the electrical parameter. The method further includes determining the value of the electrical parameter corresponding to a change in the time rate of change of the electrical parameter, wherein the change in the time rate of change of the electrical parameter exceeds a predetermined threshold, and controlling electrical power applied to the heater so as to maintain the temperature of the heater about a target temperature that is a predetermined level below the heater temperature at the time at which said change in the time rate of change of the electrical parameter exceeds the predetermined threshold.

  • Patent number: 9581912
    Abstract: The disclosure provides a method of determining an actual input value of an input variable for a control unit of a microlithography imaging device. The actual input value is assigned to a first location of the microlithography optical imaging device. The method includes: a) detecting, at a second location of the microlithography optical imaging device, an actual detection value of a detection variable of a detection device of the microlithography optical imaging device; b) using a second relation to computationally ascertain an actual computational value of the detection variable at the second location; c) comparing the actual computational value of the detection variable with the actual detection value of the detection variable to provide a result; and d) based on the result in c), using a relationship between a first predefinable relation and the second relation to correct the predefinable first relation.

  • Patent number: 9578702
    Abstract: PWM-based dimming techniques are provided for lighting systems. The techniques can be used to eliminate or otherwise reduce the potential for strobing and flickering, and may be implemented, for example, in a driver suitable for powering LED lighting systems, but can be used with other suitable light sources as well. In an example embodiment, the potential for line frequency induced flicker, or even line disturbances that are periodic with the line frequency, can be eliminated or reduced by synchronizing the PWM frequency to the line frequency or so-called mains frequency, and the potential for strobing can be eliminated or reduced by either using a randomized phase angle on a cycle-to-cycle basis or by using multiple PWM LED drive circuits all having constant cycle-to-cycle phase angle but a different phase angle from drive circuit to drive circuit (or different from LED string to LED string, as the case may be).
