摘要： A dryer control including capacitive sensing means which makes contact with fabric within the dryer. The resistivity of the fabric is a function of the moisture retained therein and determines the level of alternating current which flows through the capacitive sensing means. Current is monitored by a control circuit including a multistate transistorized amplifier which serves to disable an SCR which is connected in series with a timing mechanism. As the fabrics dry and become less conductive, less alternating current is transmitted by the capacitive sensor, de-energizing the control circuit and enabling the SCR, which allows current to pass through the timing mechanism.

摘要： A cooking appliance for inductively heating a cooking utensil comprises a flat induction heating coil mounted beneath a nonmetallic support with a substantially unbroken utensil supporting surface. The induction heating coil is driven with an ultrasonic frequency wave generated by a static power conversion circuit typically formed of a rectifier and an inverter. The inverter is a series capacitor commutated sine wave inverter with a variable output frequency, variable input voltage, or variable commutating components to adjust the utensil heating level. The inverter is also controlled in on-off mode by a utensil temperature sensor.
