    • A short message sending method, a short message service center (SMS-SC) and a gateway are provided. The short message service center constructs a message body for bearing short message, includes routing information of the short message in this message body, and sends the message body to a short message mobile switching center gateway; after receiving the message body and determining that the message body includes the routing information of the short message, the short message mobile switching center gateway sends the short message to a core network service node according to the routing information. The SMS-SC sends the obtained routing information together with the short message to an SMS-GMSC, so that the SMS-GMSC does not need to request the routing information from an HSS or an HLR, which can reduce the interactive signaling, save the network resources, and optimize the system performance.

    • Traditional temperature-control products have the problem that the temperature of the working surface reaches the setting temperature too slowly when heating up or recovering from a temperature drop. A traditional temperature control circuit and temperature-settings selector components are modified to solve this problem. When heating begins, the modified circuit increases the initial setting temperature to be above the target setting temperature. The modified circuit then adjusts the setting temperature by measuring the heating power consumption. Once the working surface of the temperature control product reaches the initial setting temperature, the heating power consumption drops and the modified circuit reduces the temperature setting to the target setting temperature. The temperature control product can rapidly achieve the target temperature. A positive-temperature-coefficient heating component is used in the temperature control product.
    • 传统的温度控制产品存在如下问题:当加热或从温度下降恢复时,工作表面的温度达到设定温度太慢。 传统的温度控制电路和温度设置选择器组件被修改以解决这个问题。 当加热开始时,修改的电路将初始设定温度提高到高于目标设定温度。 然后,修改的电路通过测量加热功率消耗来调节设定温度。 一旦温度控制产品的工作表面达到初始设定温度,加热功率消耗下降,修改后的电路将温度设置降低到目标设定温度。 温控产品可以快速达到目标温度。 在温度控制产品中使用正温系数加热部件。

    • A semiconductor integrated circuit (IC) acts as a controller of a heating-controlled device or appliance. A heating body has a positive temperature coefficient and acts as both a heating element and a temperature sensor. A Silicon-Controlled Rectifier (SCR) switches AC current to the heating body to increase its temperature. When the SCR switches off, temperature sensing is performed using a sampling resistor, isolation diode, voltage comparator, and switch for a low-voltage DC supply are formed on an integrated circuit that has a first circuit branch and a second circuit branch. A compensation diode and a compensation resistor can be added in parallel to reference resistors. The compensation diode compensates for the forward voltage drop of the isolation diode that would otherwise create an inaccurate temperature measurement. The diodes have the same temperature response, allowing for a more accurate temperature measurement over a full temperature range of the sensorless appliance.
