摘要： 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.

摘要： A linear heater control circuit has a more linear relationship between sensed temperature and a variable resistance. As the user adjusts the variable resistance, the temperature increases linearly rather than abruptly. The linear control circuit has a parallel resistor that is in parallel with the variable resistor and one or two series resistors that are in series with the variable resistor. The tap of the variable resistor is input to a comparator that compares the tap voltage to a reference voltage and adjusts a trigger to a Silicon-Controlled Rectifier (SCR). The SCR switches AC current to a heating element to increase its temperature. When the SCR switches off, temperature sensing is performed using a voltage network that includes the parallel resistor and the variable resistor. A switch or diode isolates the voltage network from the heating element during heating to protect the comparator.

摘要： 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.

摘要： An electronic switch can replace a standard mechanical light switch for 110-240 volt alternating-current (A.C.) devices. A triac switches the A.C. current to an A.C. device such as a light. A rectifier bridge generates a direct-current (D.C.) voltage that is applied to a special current limiter. The special current limiter generates a large current peak at low voltages, but limits current at high voltages. The large current peak from the special current limiter charges a capacitor when voltage is low at the beginning of each A.C. half-cycle, before the triac turns on. The capacitor has enough charge to supply D.C. current to an Infrared detector and trigger control logic for the rest of the A.C. half-cycle. When the detector detects a person nearby, it signals the trigger control logic. The D.C. voltage from the rectifier bridge is filtered to generate a sync pulse to the trigger control logic when adds a phase delay to the sync pulse which triggers the triac.
摘要翻译：电子开关可以替代110-240伏交流（交流）装置的标准机械灯开关。三端双向可控硅开关将交流电流切换到交直流设备，如灯。整流桥产生施加到特殊限流器的直流（直流）电压。特殊电流限制器在低电压下产生大电流峰值，但限制高电压下的电流。在三端双向可控硅开关导通之前，每个交流电半周期的电压低电平时，特殊电流限制器的大电流峰值将对电容器充电。电容器具有足够的电荷，以将红外线检测器的电流提供给红外检测器，并触发交流半周期的其余部分的触发控制逻辑。当检测器检测到附近的人时，它会发出触发控制逻辑信号。当对触发三端双向可控硅开关元件的同步脉冲添加相位延迟时，来自整流桥的直流电压被滤波以产生到触发控制逻辑的同步脉冲。

摘要： A coating that exhibits resistance to fouling by waterborne contaminants, and permselective membranes having this type of coating, are disclosed. For example, a reverse osmosis membrane is coated with a hydrogel-like composition comprising a combination of a hydrophilic polymer, a polyphenolic compound, and a surfactant, whereby the membrane is made more resistant to fouling by organic contaminants. Particularly beneficial are coating compositions containing amine-based surfactants, these being retained in the hydrophilic coating by polar or ionic binding forces.
