Abstract: A method in a clocked integrated circuit receiving an input clock signal having a clock frequency and a command signal for accessing a memory element in the clocked integrated circuit. The method detects the input clock signal having a clock frequency above or below a frequency threshold. The method generates a clock detect output signal having a first logical state in response to the clock frequency being below the frequency threshold and generates the clock detect output signal having a second logical state in response to the clock frequency being above the frequency threshold. The method delays the command signal by a first timing latency to generate a timing adjusted control signal where the first timing latency is one or more clock periods of the input clock signal. Finally, the method adjusts the first timing latency in response to the clock detect output signal.

Abstract: A cooking appliance having a thermocouple for measuring the temperature of an electrically conducting cooking utensil is provided. The cooking appliance includes a first probe formed of a first electrically conducting material and a second probe formed of a dissimilar second electrically conducting material. The first probe and second probe are spaced from one another. When the cooking utensil is placed on a heating assembly and heat is applied thereto, the first probe and the second probe electrically contact the cooking utensil. The cooking utensil acts as an intermediate material and completes the thermocouple circuit thereby allowing current to flow between the probes. Consequently, a voltage differential is produced. The voltage differential is measured, and as the voltage differential is indicative of the temperature of the cooking utensil, the temperature of the cooking utensil may be determined.
