    Abstract: The adaptive temperature controller system includes a device for measuring resistance, an electrically-conductive material, a power supply, and a device for controlling power. In operation, the controller determines the resistance of material at one or more temperatures and therefore determines the resistance of the material through a range of operating temperature. Based on such determination so long as voltage and power are known, the resistance of the material, and therefore its temperature, are known. As a result the voltage or power may be instantly varied to produce near infinite control over material temperature.

A waveform setter sets the waveform of the pulse signal, based on the contents of input from an input unit. With electrical charge accumulated in the capacitor, a pulse signal is output to the gate of the switching element so that the flash lamp emits light intermittently. A change in the waveform of the pulse signal applied to the switching element will change the waveform of current flowing through the flash lamp and, accordingly, the form of light emission, thereby resulting in a change in the temperature profile for a semiconductor wafer.

  • Patent number: 8392027
    Abstract: A spa control system that measures the flow of water through the heater and accurately reports water temperature in the spa using only one solid-state sensor in the heater. The rate of flow is determined by energizing the pump, with the heater still de-energized, and observing the rate in which the moving water cools the inside of the heater. If there is no circulation of water through the heater, the temperature of the sensor will continue to rise from the energy applied when the heater was briefly energized. This rise will be quite significant and a clear indication of a flow problem. If the flow is found to be adequate, the heater will be energized for a normal period of time. The sensor is now carefully monitored for a sudden increase in temperature, which would indicate loss of a normal flow of water.

  • Patent number: 8324538
    Abstract: Systems and methods to source a resistive load, such as a heating resistor, to control temperature while adhering to a specified power draw budget and/or a specified root mean square (RMS) current limit. For example, a sensor block assembly (SBA) heater controls temperature of a MEMS device in a sensor block assembly while adhering to the power draw budget and/or an average current limit. An exemplary embodiment generates a pulse width modulation (PWM) control signal, controls a switch in accordance with the control signal, sources the resistive load from a power source in accordance with the controlled switch, and modifies the duty factor of the switch to reduce the power drawn by the resistive load in response to the power drawn by the resistive load exceeding a power limit defined by a slope-intercept curve. The limiting of power into a resistor load limits the RMS current drawn by that load.

    Abstract: A heating apparatus includes a heater, a current-feed switching circuit configured to switch turning-on/off of current-feeding from an AC power source to the heater, thereby feeding current from the AC power source to the heater at a predetermined current-feed ratio, a temperature detector configured to detect a heating temperature of the heater, and a current-feed controller configured to control the current-feed ratio of the current-feed switching circuit such that the detection temperature of the temperature detector falls within a target range. The current-feed controller performs at least one pair of ON lock current-feed control to fix the current-feed ratio to almost 100% in a first period and OFF lock current-feed control to fix the current-feed ratio to almost 0% in a second period every predetermined control period of the current-feed switching circuit.

    Abstract: A method and computer program for the control of the heat treatment of batches of metal workpieces for increasing the degree of automation of industrial furnace plants presumes an identical batch layout, an identical treatment program, and an identical article geometry of metal workpieces and relates it to a model batch, which has been run using batch thermoelements. The model batch becomes the foundation for a new batch. Through the assumption of program parameters of the actually run process of the model batch into the program of the new batch to be run, new batch thermoelements are not required for the new batch to be run.

  • Patent number: 8269145
    Abstract: The invention relates to a method for operating a heating element in a motor vehicle by pulse width modulation, wherein fluctuations in the supply voltage are compensated for by adapting the duty cycle so as to achieve a desired heating output. According to the invention, during a voltage pulse the voltage that is present at the heating element and/or the current flowing through the heating element are measured at specified intervals, and the measured values or values determined therefrom are added to calculate a sum value, which rises with the energy that is fed into the heating element by the voltage pulse, and the voltage pulse is ended at the latest when the sum value has reached a target value. The invention furthermore relates to a glow plug controller for carrying out the method according to the invention.
