  • Patent number: 6129007
    Abstract: An electric automatic pop-up toaster has a carriage and a pivotably connected manually operative arm for moving the carriage to a lowermost position for toasting in well-known manner. At the beginning of each toasting cycle, the arm is horizontal and a latching plate is magnetically held down to hold the arm and the carriage in a lowermost position. The arm presses against a wire spring to hold closed a power switch (not shown) that supplies power to heating elements of the toaster. The latching plate is (magnetically) released at the end of each toasting cycle by a timer. This allows the carriage to move upwards to pop-up toasted bread in a usual way. However should the carriage fail to move upwards when the latching plate is released, the arm is pivoted by a spring and tilted to the position shown in the Figure. The wire is therefore released and enters a slot in a bracket mounted to the carriage. The switch opens and remains open to prevent power being re-instated to the heating elements.

  • Patent number: 6077552
    Abstract: A method and apparatus is provided for the monitoring of the doneness of a baked product without invasively contacting the baked product. An impact is directed against a side of the baked product, and the resulting flex distance due to the propagation of the impact through the baked product is measured. Both the impact and the resulting flex are preferably performed without direct physical contact with the baked product. The flex response time from the impact is compared to a pre-stored threshold, and if the flex response time is less than the threshold, a doneness signal is generated. The doneness signal may be used, for example, to control the baking process, and can be used for the automated monitoring of baked products in a commercial baking environment. The doneness signal can further be used, for example, to control either the baking dwell time, the oven temperature, or both, or to control other baking variables.

  • Patent number: 5662025
    Abstract: Disclosed is a control circuit for an electric cooker. In the control circuit of the electric cooker, a voltage selection supply rectifies a selected voltage, and applies it to a voltage sensor. The voltage sensor compares the voltage from a power supply controller with a reference voltage from a time proportion temperature controller, and applies the result to a temperature controller. The temperature controller has a time controlling resistor. The time proportion temperature controller generates a time proportion control signal having a constant period, and applies the time proportion control signal to the power supply controller. Simultaneously, a switching mode temperature controller having a thermal sensor generates a heater control signal according to a heater temperature sensed by the thermal sensor, and the heater control signal to the power supply controller.

  • Patent number: 5628242
    Abstract: An activity monitor for a gas cooker or grill which monitors activity with a motion detector. When the grill has not been used for a preselected time period, the gas supply is automatically shut off to avoid fire hazard and/or wasting of fuel. An adjustable timer is used to activate the automatic shut off of the gas supply only after no motion has been detected for a preselected time period. A default timer value can be used when the grill is initially activated. If motion is detected prior to gas supply shut off, then the timer is reset to zero. Motion detection is accomplished by one or more methods including a lid position sensor to detect when the grill lid is moved between the open and the closed position a motion detector which monitors switch usage to detect activity, and vibration or movement monitors.
