A method of predicting the temperature of a resistive heating element in a heating system is provided. The method includes obtaining resistance characteristics of resistive heating elements and compensating for variations in the resistance characteristics over a temperature regime. The resistance characteristics of the resistive heating element include, but are not limited to, inaccuracies in resistance measurements due to strain-induced resistance variations, variations in resistance due to the rate of cooling, shifts in power output due to exposure to temperature, resistance to temperature relationships, non-monotonic resistance to temperature relationships, system measurement errors, and combinations of resistance characteristics. The method includes interpreting and calibrating resistance characteristics based on a priori measurements and in situ measurements.

A heater assembly includes a container including a cylindrical portion that forms a chamber in which a flavor generating article is contained, and a heater arranged in a peripheral surface of the cylindrical portion. The container includes a first channel extending along a longitudinal direction of the cylindrical portion and located adjacently to the chamber in a direction intersecting with the longitudinal direction of the cylindrical portion, and a second channel extending through the chamber along the longitudinal direction of the cylindrical portion. The first channel is in communication with the second channel.

A glass-tube heater includes a glass tube, a cap, and a temperature display unit. The glass tube is provided therein with an off-water protection sensor or a tipping switch, a control circuit board, one of a TRIAC and a relay, and a heating element. The control circuit board includes a control unit (which is an MCU or a comparator). All the components that are disposed in the glass tube are electrically connected to form a control circuit. Devices for temperature control, detection, and heating are all disposed inside the glass tube. The off-water protection sensor is operable to detect if being removed out of water for controlling the heating element to carry out heating or not, thereby ensuring quick termination of heating upon removal out of water. The tipping switch is operable to control the heating element from heating in case of excessive tipping of the heater.

A split-type car cigarette lighter includes a cigarette lighting device and a car charging device movably connected to the cigarette lighting device. The cigarette lighting device includes a first housing formed a first receiving room therein for receiving a first PCB and a battery therein, and a heating plate electrically connected to the first PCB. The battery is tightly fixed with the first housing and electrically connected to the first PCB. Both the heating plate and the first PCB are tightly fixed with the first housing. the heating plate is electrically connected to the at least one electrical contact when the cigarette lighting device is partially received in the first mounting recess and movably connected to the second housing. The structure can accordingly not only realize the electronic heating function of a cigarette lighter and conveniently carry, but also have at least one charging interface to conveniently and optionally charge mobile phones, tablet computers and other electronic devices through the charging interface.

An electric ice press is provided herein and may be utilized to reshape an initial ice billet into a sculpted ice nugget. The electric ice press may include a mold body having a first mold segment and a second mold segment movable relative to each other. A heated guide rail extends between the first mold segment and the second mold segment to transfer heat from the first mold segment to the second mold segment. The heated guide rail may be a heat pipe for transferring heat generated by a base heater in the first mold segment or an electrical resistance heating rod for generating heat, either of which requires only a single power cord electrically coupled to only the first mold segment.

A resistive heater capable of delivering heat loads on the same order as those produced by in-pile nuclear fuel experiments. The heater rod provides the energy for high-temperature steady-state testing, as well as the power needed to simulate the transient pulse in the Transient Reactor Test Loop (TRTL) system. The resistive heater includes a removable housing, two or more thermal conductors in the housing; and one or more stabilizers coupled to the two or more thermal conductors to keep the two or more thermal conductors separated to avoid shorting, wherein the two or more thermal conductors are coupled to the housing via an inert gas (e.g., Helium). The two or more thermal conductors comprise a material with substantially zero infrared spectrum (e.g., sapphire, silica, or glass).
