Abstract: A cookware item includes: a cooking container for receiving food to be cooked and/or a lid for closing the cooking container; at least one handle for handling the cookware item, a handle body of the handle being force-transmittingly connected to the cooking container and/or to the lid of the cookware item by a handle connection part of the handle; an insulating part of the cookware item being disposed between the handle connection part and/or the lid to reduce a transfer of heat to the handle body; and an output unit at least partially integrated into the handle body and for visually outputting information to a user of the cookware item, the output unit having at least one light source, the light source being controllable by a controller of the cookware item and configured to be supplied with electrical power by a power source of the cookware item.

Abstract: A system and method for initial calibration of an air-quality sensor device. The method includes establishing at least a reference response to an environmental condition based on a response of at least one calibrated detector to the environmental condition; establishing at least a sensor response to the environmental condition based on the response of at least one uncalibrated detector to the environmental condition; developing, based on the established sensor response, at least a sensor response slope; determining, based on the established reference response, the established sensor response, and the developed sensor response slope, at least a corrected response; and returning the corrected response.

Abstract: A temperature control circuit of an oven controlled crystal oscillator (OCXO) is provided. A first and a second digital potentiometer are correspondingly arranged in a bridge circuit which outputs a voltage to an input terminal of a differential amplifier (OPAMP), wherein the resistance value of the first digital potentiometer is adjustable so as to adjust the temperature of the oven to the peak temperature of the crystal resonator, and the resistance value of the second digital potentiometer is adjustable so as to cancel the temperature gradient of the first digital potentiometer. In the temperature control circuit of OCXO, the heat generation of the heater resistor is controlled by the power transistor based on the control voltage from the differential amplifier.
