  • Method of controlling the operation of a cooking appliance
    Patent number: 6060698
    Abstract: An integrated circuit constructed to provide control functions to a toaster oven cooking appliance. Said control functions including compensation for input voltage fluctuations, compensation for residual heat due to recycling, audible signal generation, multiple mode selection, safety shut off and others. The integrated circuit also provides flexibility to accommodate multiple models of an appliance in a product line.

  • Sound activated device and method
    Patent number: 5012223
    Abstract: A smoke alarm activated device includes a sound receiver and signal converting device for receiving a sound wave analog signal emitted from a smoke alarm in response to the sensed presence of smoke. The signal is received and converted into a digital signal containing the informational characteristics contained within the transmitted sound wave. The digital signal is detected in a first time period which first time is identical to the time period in which the sound wave is generated. The absence of the digital signal in a second time period is detected, which second time period is identical to the time period in which the detected sound wave is absent. An output control signal is generated when the presence of the digital signal is detected in the first time period and the absence of the digital signal is detected in the second time period. A device is activated in response to the output control signal.
