  • Patent number: 5678925
    Abstract: A hot beverage mug automatically senses the temperature of its liquid contents and generates an accurate aural and/or visual indication of the temperature sensed. The temperature is sensed by a thermistor in a resistive capacitive (R/C) circuit which operates to yield a signal of variable frequency corresponding to the temperature sensed. An integrated circuit (IC) logic controller treats this electrical signal as an input which triggers a further electrical signal from the IC controller to an aural or visual display generating device such as an annunciator, a light emitting diode (LED), liquid crystal display (LCD) or a simulated voice expressing the temperature sensed. The power for the R/C circuit, the IC and the aural/visual indicator(s) is supplied from a battery and controllable by a switch activated either manually or automatically upon sensing the pressure of the liquid contents or by physical contact with the mug handle.
