摘要： The present invention provides a control system for a heating unit in a cooktop that is capable of detecting the presence (or absence) of a cooking pan or utensil. The heating unit has a spirally wound ribbon heater element and may be mounted below a glass-ceramic cooking surface. The control system includes a pan detection unit electrically connected to the heater element. The pan detection unit generates a high frequency signal through the heater element to determine whether a pan is present on the cooktop. The pan detection unit may have an oscillation circuit to generate the high frequency signal through the heater element. In one embodiment, the control system further includes at least one switch device that is connected between the heater element and a power source. The switch device is opened to remove the heater element from the power source when the pan detection unit generates the high frequency signal through the heater element. The present invention also includes a heating unit having dual heater units to determine the size of the pan placed on the cooktop. The present invention further includes methods of operating a heater unit and control system having the capability of detecting the presence of a pan.

摘要： A microcomputer of a household appliance, such as a microwave oven, receives input data from the user for operating the various functions of the appliance. The data is stored in the volatile memory of the microcomputer. The data is compressed into a bit pattern which is representative of all the bits in the volatile memory in the event of a power interruption. The compressed bit pattern is stored in the volatile memory of the microcomputer to be later verified. The operations of the microcomputer is continued for those functions which do not affect volatile memory until the power source is restored or the microcomputer is reset. In either case the volatile memory is verified by generating a compressed bit pattern for current data. The current bit pattern is then compared to an initial bit pattern. If the bit patterns are identical then the volatile memory has not been corrupted by an interruption of power exceeding a preselected "data vaild time". Also the fixed bit pattern is verified against a fixed bit pattern in nonvolatile memory to determine if any corrpution has occurred. If no corruption has occurred the normal operations continue. If it has been determined that the volatile memory has been corrupted, then the microcomputer is reinitialized with default data copies from nonvolatile memory to volatile memory.
摘要翻译： 诸如微波炉的家用电器的微计算机从用户接收用于操作器具的各种功能的输入数据。 数据存储在微型计算机的易失性存储器中。 在电源中断的情况下，数据被压缩成代表易失性存储器中的所有位的位模式。 压缩比特模式存储在微型计算机的易失性存储器中，以便后续验证。 直到电源恢复或微计算机被复位为止，对于不影响易失性存储器的那些功能，微型计算机的操作才能继续。 在任一种情况下，通过为当前数据生成压缩位模式来验证易失性存储器。 然后将当前位模式与初始位模式进行比较。 如果位模式相同，则易失性存储器没有被超过预选的“数据空闲时间”的功率中断所破坏。 此外，固定位模式针对非易失性存储器中的固定位模式进行验证，以确定是否发生了任何校正。 如果没有发生腐败，则正常操作继续。 如果确定易失性存储器已损坏，则微处理器将从非易失性存储器到易失性存储器的默认数据副本重新初始化。

摘要： An improved capacitive drop power supply is provided for use in home appliances. The power supply circuit includes: a rectifier for converting an AC power source to a DC voltage; a current limiting capacitance interposed between the AC power source and the rectifier; a low voltage output stage and a higher voltage output stage. The low voltage output stage supplies DC voltage from the rectifier to a microcontroller residing in the home appliance. The higher voltage output stage is connected in series with the low voltage stage and supplies DC voltage to the higher voltage loads associated with the home appliance. To reduce power consumption, a shunt circuit path is connected in parallel across the higher voltage output stage which causes a phase shift in the AC power signal and thereby reduce real power consumption when a no load condition is placed on the output stage (e.g., during a standby operating condition of the home appliance).

摘要： A power controller for an appliance, especially a washing machine, is operative to place the appliance into a hyperspin mode. When in the hyperspin mode, the washing machine rotates its washing basket at a higher speed in relation to a traditional spin mode for the washing machine. In order to prevent damage to the washing machine that could result from spinning heavier, unbalanced loads at higher speeds (i.e. hyperspin speeds), a controller detects vibration of the washing machine basket while the items are being spun at a lower speed (i.e. at the speed of the traditional spin mode). If the washing basket vibration is less than a predetermined threshold vibration value, the washing machine controller operates to cause the washing machine to rotate its washing basket at a higher speed. This results in removal of more water from the clothes being spun dried.
