The present invention provides a hot knife, which includes a blade, a heat source, a handle, and a power source. The blade includes a central portion extending along a central axis, two wing portions integrally extending outwardly from two opposite sides of the central portion in a radial direction of the central axis, and a chamber defined by inner walls of the central portion and two wing portions. The heat source is disposed in the chamber and is adapted to supply heat to the blade. The handle is attached to the blade. The power source is disposed in the handle and is electrically connected to the heat source.

A two-in-one car cigarette lighter includes a first housing, a second housing connected to the first housing and a heater partially received in the second housing. The first and second housings cooperatively form a receiving room for receiving a battery and a PCB therein. The battery is electrically connected to the PCB and the PCB is tightly fixed with the first housing. A first port and a second port are perpendicularly and electrically connected to the PCB and formed parallel to each other. The second housing includes a first mounting recess so that the heater can pass through the first mounting recess to electrically connect to the PCB. The structure can accordingly not only realize the function of a cigarette lighter, 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.

The invention relates to a heating system for heating a living being, for instance, a person (2) within a vehicle (1) being preferentially a hybrid car or an electric car. The heating system comprises an infrared laser system (5, 6) for illuminating the living being with infrared laser light, thereby heating the living being. Thus, heating radiation is used, which has a high collimation and which can be focused relatively easily. The heating can therefore be confined to a certain region, in which the living being is located. The heating can even be confined to the living being or to parts of the living being only. This more focused heating allows for a reduction of the energy consumption.

A heater system is provided that includes a base functional layer having at least one functional zone. A substrate is secured to the functional member, and a tuning layer is secured to the substrate opposite the base functional layer. The tuning layer includes a plurality of zones that is greater in number than the zones of the base functional layer, and the tuning layer provides lower power than the base functional layer. A component is secured to the tuning layer opposite the substrate, and the substrate defines a thermal conductivity to absorb and dissipate a requisite amount of power from the base functional layer. A control system is also provided that has a plurality of addressable control elements in electrical communication with power lines and with the tuning layer, the control elements providing selective control of the tuning layer zones.

The invention relates to a liquid reservoir (34) for an electronic smoking device (10), an atomizer/liquid reservoir portion (14) with a liquid reservoir (34) for an electronic smoking device (10) and to an electronic smoking device (10) with a liquid reservoir (34). In order to be able to provide gaseous material that has not been atomized by an atomizer (26) of the electronic smoking device (10), the liquid reservoir (34) comprises first and second storage volumes (40, 42) that are each in communication with a liquid outlet (46) or a fluid outlet (50), wherein the liquid outlet (46) and the fluid outlet (50) are arranged one after the other in a longitudinal direction (L) of the liquid reservoir (34).

A method for manufacturing an electrostatic chuck with multiple chucking electrodes made of ceramic pieces using metallic aluminum as the joining. The aluminum may be placed between two pieces and the assembly may be heated in the range of 770C to 1200C. The joining atmosphere may be non-oxygenated. After joining the exclusions in the electrode pattern may be machined by also machining through one of the plate layers. The machined exclusion slots may then be filled with epoxy or other material. An electrostatic chuck or other structure manufactured according to such methods.

A tankless water heater includes a heater assembly, a temperature sensor, a flow sensor, a first heating element, a second heating element, and a controller. The heater assembly includes a water inlet, a water outlet, and a heating chamber defining a water flow path between the water inlet and the water outlet. The temperature sensor measures the temperature of water flowing through the heating chamber. The flow sensor measures a flow condition of water within the heating chamber. The first and second heating elements are located in the heating chamber and include first and second wattages, respectively. The second wattage is different from the first wattage. The controller is coupled to the first and second heating elements and the temperature and flow sensors. The controller is configured to regulate the amount of electrical current flowing through the first and second heating elements in response to the flow condition.
