An electronic cigarette includes a processor, a heating element, and a power supply. The heating element is electrically coupled to the processor. The power supply is electrically coupled to the processor and the heating element. The processor is configured to calculate a resistance value R.sub.L of the heating element before the heating element is powered on, determine whether the resistance value R.sub.L of the heating element is within a predetermined range, and determine whether a temperature control mode is selected when the resistance value R.sub.L of the heating element is within the predetermined range. The processor is configured to determine whether the heating element is adapted to the temperature control mode when the temperature control mode is selected, and control the heating element to work in the temperature control mode when the heating element is adapted to the temperature control mode. A related temperature control method is also provided.

A system and method for preheating a cooking chamber of an oven appliance is provided. The oven appliance may include one or more heating elements that operate according to a control algorithm that prevents the center oven temperature from exceeding a maximum desired temperature threshold. The control algorithm accounts for discrepancies between the measured oven temperature and the actual center oven temperature, particularly when preheating a cold oven. As a result, the control algorithm selectively operates one or more of the heating elements after the measured oven temperature is above the maximum desired temperature threshold. Preheating the cooking chamber in this manner will improve overall cooking performance.

An improved incubator and control apparatus include separate temperature and humidity control loops wherein a commanded temperature and a commanded relative humidity (RH) value are commanded to the control apparatus via a user interface. The control apparatus employs a humidifier rate saturation controller which acts responsive to both a humidity control signal and a current temperature to regulate the addition of humidity to the air within the incubator assembly to avoid a transient humidity from exceeding a predetermined value and thereby avoiding the generation of condensation within the incubator.

In one embodiment, a remote monitoring system for a fluid applicator system is disclosed. The fluid applicator system is disposed to heat and pump spray fluid, and to transmit reports including sensed temperatures, pressures, and other operational parameters of the fluid applicator system via a wireless network. The remote monitoring system comprises a data storage server, and an end user interface. The data storage server is configured to receive and archive the reports. The end user interface is configured to provide a graphical user interface based on the reports. The graphical user interface illustrates a status of the fluid handling system, sensed and commanded temperatures of the fluid handling system, sensed and commanded pressures of the fluid handling system, and usage statistics of the fluid handling system.

Apparatus and methods are disclosed for controlling a cooling ventilation fan after the thermostat call for cooling has ended by providing a variable fan-off delay time based on cooling system parameters including but not limited to the cooling system operating time, duration of the thermostat call for cooling, relative humidity, temperature split, thermostat temperature rate of change, or thermostat temperature reaching a minimum inflection point or crossing a fixed or variable thermostat differential or differential offset. Apparatus and methods are disclosed for controlling a heating ventilation fan after the thermostat call for heating has ended by providing a variable fan-off delay time based on heating system parameters including but not limited to the heating system operating time, duration of the thermostat call for heating, temperature rise, thermostat temperature rate of change, or thermostat temperature reaching a maximum inflection point or crossing a fixed or variable thermostat differential or differential offset.

A family of wall-mounted electrical fixtures, both for lighting control and electrical power or signal delivery, having a modular design. Said modular design predominately isolating those components that are directly connected to in-wall wiring within a wall-mounted base and low-voltage control and communication components, such as sensors, user-interface elements, programmable logic and wireless communication modules, within an aesthetically-appealing, easily-detachable faceplate assembly.

A thermostat for controlling an HVAC system is described, the thermostat having a user interface that is visually pleasing, approachable, and easy to use while also providing ready access to, and intuitive navigation within, a menuing system capable of receiving a variety of different types of user settings and/or control parameters. For some embodiments, the thermostat comprises a housing, a ring-shaped user-interface component configured to track a rotational input motion of a user, a processing system configured to identify a setpoint temperature value based on the tracked rotational input motion, and an electronic display coupled to the processing system. An interactive thermostat menuing system is accessible to the user by an inward pressing of the ring-shaped user interface component. User navigation within the interactive thermostat menuing system is achievable by virtue of respective rotational input motions and inward pressings of the ring-shaped user interface component.

A vibration-proof spring, which coaxially inserts a shaft, is provided in a body of a control valve. The vibration-proof spring includes a cylindrical spring body, spring parts, which are integrally formed with a side wall of the spring body and are supported by the spring body in a cantilevered manner, and bulging portions, which are formed, on surfaces of the spring parts facing the shaft, in a protruding manner. The spring body is formed as a cylindrical body such that a plate-like body, which is obtained by punching a metallic plate through a press-forming process, is bent along a longitudinal direction of the plate-like body. Also, the spring body is formed in such a manner as to have edge parts that protrude radially outward from at least one of ends of the cylindrical body in the direction of axis line.

A drive circuit of a temperature adjustment apparatus drives a Peltier element at a desired output amount. A state detector detects an electrical state of the Peltier element. A control circuit calculates a desired output amount based at least on the electrical state of the Peltier element, determines a control quantity for driving the Peltier element at the desired output amount, and controls the drive circuit at the control quantity.

An electronic cigarette (“e-Cig”) may include functionality for monitoring and controlling the thermal properties of the e-Cig. The system and method described herein may monitor a temperature based on a resistor (i.e. hot wire) near the wick and model the thermal cycle of an e-Cig. The model can be used for controlling the temperature of the e-Cig and preventing burning. The temperature control may dictate optimal conditions for atomization and smoke generation in an e-Cig while avoiding hotspots and burning to the atomizer or cartomizer.
