    • A method for controlling a device temperature measures a parameter related to device power consumption and utilizes the parameter to control the device temperature. This can be achieved with a system including a heat exchanger, a power monitor, and a circuit which controls the temperature setting of the heat exchanger. The circuit uses as inputs the power level, heat exchanger temperature, and set point. The system thus eliminates the need for temperature sensing devices in or connected to a chip, responds to the temperature of the device and not the package, can be used for high volume chip manufacturing, does not require significant surface area of a device for temperature sensing, and eliminates the need for chip power profiles. Significantly, the system allows a set point to be maintained with minimal overshoot or undershoot.
    • 用于调节设备温度的方法技术领域本发明涉及一种用于调节设备温度的方法,包括测量与设备能量消耗相关的参数并且使用所述参数来调节设备的温度。 为了实现这种热调节,使用包括热交换器,功率控制器和用于调节热交换器的温度的电路的系统。 该电路用作输入功率水平,换热器温度和设定点。 本发明的系统避免使用布置在芯片中或连接到芯片上的温度传感器。 它能够响应设备的温度而不是外壳的温度; 它可以用于大规模生产芯片; 它只需要一小部分设备来检测温度; 并且使得芯片的功率分布变得不必要。 另外,该系统限制设定点周围的正向和负向超限。

    • An ohmic heating process in which liquid foodstuffs material is pumped from an inlet (4) to an outlet (5) past electrodes (2, 3) that receive ac power to heat the liquid, and the outlet temperature is controlled within a predetermined range using a microprocessor (9) that operates a power supply controller (10). The processor (9) considers the liquid between the electrodes (2, 3) to comprise a series of elements moving from the inlet to the outlet and predicts the outlet temperature that will occur for each of the elements upon reaching the outlet. The power level applied to the electrodes (2, 3) is adjusted if any of the predicted outlet temperatures for the elements falls outside of a predetermined range.
    • 将液体食品材料从入口(4)泵送到出口(5)的欧姆加热过程通过接收交流电力以加热液体的电极(2,3),并且将出口温度控制在预定范围内,使用 操作电源控制器(10)的微处理器(9)。 处理器(9)认为电极(2,3)之间的液体包括从入口移动到出口的一系列元件,并且预测到达出口时每个元件将出现的出口温度。 如果元件的预测出口温度的任何一个都超出预定范围,则调整施加到电极(2,3)的功率电平。
