An environmental control device for aquariums, ponds, or terrariums includes: a casing; an environmental control device, adapted to control an environmental condition of the aquarium, pond, or terrarium; and an NFC communication device configured to communicate with an external unit. The external unit is configured to exchange data with the NFC communication device so as to monitor and/or control an operating parameter of the environmental control device or an operating condition of the environmental control device or environmental condition of the aquarium, pond or terrarium.

Methods and apparatus include a hair iron having a controller and a heater between first and second arms movable relative to each other between open and closed positions. The controller connects or not the heater to a line voltage to heat hair when placed between the arms during use. A proportional-integral-derivative (PID) controller communicates with a thermistor measuring a current temperature of the heater and makes requests of the controller to operate the heater at a setpoint temperature. In various embodiments, the heater heats to full power during warm-up and operates thereafter at lower temperatures based on a reading of the line voltage and a time to adjust the current temperature to the desired setpoint temperature.

An appliance having a heater connectable to a power source to create a heater circuit is disclosed. The appliance includes a controller and a heater switch configured to be selectively closed in response to a control signal from the controller to complete the heater circuit and enable current to flow from the power source to the electric heater. The appliance further includes a heater feedback circuit comprising a plurality of resistors and configured to be connected to the power source and further configured to generate an output signal to the controller having a first state indicative of no current leakage from the heater circuit, a second state indicative of current leakage from the heater circuit where the polarity of the power source is normal, and a third state indicative of current leakage from the heater circuit where the polarity of the power source is reversed. The controller may determine whether current leakage exists in the heater circuit, regardless of the polarity of the grid lines from the power source. The controller may take various actions in response to such determination.

A heated retractable leash is disclosed which increases the comfort of the user by heating the housing of the retractable leash during cold or inclement weather.

An information handling system includes a battery, a first temperature sensor, an electric heater, and a processor. The battery provides power to one or more other components of the information handling system. The first temperature sensor measures a temperature within the information handling system. The electric heater receives a current, and provides heat to the battery based on the reception of the current. The processor determines if the battery is in an idle or charging state. In response to the battery being in the idle state or the charging state, the processor receives an ambient temperature of the information handling system from the first temperature sensor. The processor determines whether the ambient temperature is below a first threshold temperature. In response to the ambient temperature being below the first threshold temperature, the processor provides the current to the electric heater to heat the battery.
