A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

A heater system includes an integrated heater device and a control system. The integrated heater device includes a thermocouple for measuring temperature and one or more multiportion resistive elements that are operable as heaters to create a temperature differential between the fluid and air to detect the fluid, and as sensors to measure a fluid level. The control device operates the integrated heater device as a sensor or heater based on one or more performance characteristics of the heater system and self-calibrates the heater device.

The present disclosure describes a personal vaporizer which can detect whether or not a cartridge of the personal vaporizer has been breached. The cartridge includes a conductive shell. The conductive shell can include two or more conductors which are electrically isolated from each-other. Prior to operation, the personal vaporizer can use the two or more conductors to assess whether or not an outer shell of the cartridge has been breached. In some implementations, if it is determined that the cartridge has been breached, the personal vaporizer can shut down, or otherwise fail to operate normally.

A heater system is provided. The system includes a resistive element with a temperature coefficient of resistance (TCR) of at least about 1,000 ppm such that the resistive element functions as a heater and as a temperature sensor and the resistive element is a material having greater than about 95% nickel. The system also includes a heater control module including a two-wire controller with a power control module that is configured to periodically compare a measured resistance value of the resistive element against a reference temperature to adjust for resistance drift over time during operation such that a temperature drift of the resistive element is less than about 1% over a temperature range of about 500° C.-1,000° C.

During a de-ice process, heating zones associated with a rotor may be supplied with power for shedding accreted ice from the heating zone. Priority heating zones associated with the leading edge of the rotor are supplied with power to activate the priority heating zones multiple times during the de-ice process. Heating zones associated with a lower surface of the rotor may be activated after the priority heating zones are first activated. A first dwell may be waited, to allow additional ice accretion on the priority zones. The priority heating zones may then be reactivated after the first dwell. Heating zones associated with an upper surface of the rotor may be then be activated. A second dwell may be waited, to allow additional ice accretion on the priority zones. The de-ice process may then repeat.

A system and method for providing power to moving elements on a conveyor system while the moving elements are moving. An accessory for mounting on one or more of the moving elements, which receives power from the system. Various accessories for using the power provided. In one case, the accessory is a rotary gripper that includes a body; a gripper motor; a rotation motor; and a plurality of grippers, wherein the gripper motor is mechanically connected with and configured to open and close the plurality of grippers, the rotation motor is mechanically connected with and configured to rotate the plurality of grippers. Other accessories include a gripper, a vacuum system, a heater, and a cooler.

An aerosol-generating system is provided, including: a cartridge including an aerosol-forming substrate; a resonant circuit, the cartridge including at least part of the resonant circuit, the circuit being configured to resonate at a predetermined resonant frequency associated with an identity of the cartridge; and an aerosol-generating device including: a housing to removably receive the cartridge, a power source to supply power to the cartridge, and control circuitry including a controller configured to determine a resonant frequency of the resonant circuit when the cartridge is received by the device, and identify the cartridge based on the determined frequency, the cartridge having a connection end to connect the cartridge to the device and including electrical contacts to electrically connect the cartridge to the device, and the device having a connection end to connect the device to the cartridge and including electrical contacts configured to electrically connect the device to the cartridge.

The present disclosure relates to an induction heating type cooktop and includes a case; a cover plate configured to be coupled to the upper end of the case and provided with an upper plate portion on which an object to be heated is disposed; a working coil provided inside the case; a thin film configured to be coated on the upper plate portion and to be inductively heated by the working coil; and an adiabatic material provided between the upper plate portion and the working coil, in which the thin film may be formed to have at least one closed loop that does not include a central region of the working coil.

A vaporiser assembly for an aerosol-generating system may include a capillary element made from porous glass. The capillary element has a first end and a second end. The vaporiser assembly further comprises a heater element. The first end of the capillary element is configured to be fluidically connected to a liquid storage portion. The heater element is provided at the second end of the capillary element. The pore size of the capillary element is configured to allow a liquid aerosol-forming substrate from the liquid storage portion to be conveyed from the first end to the second end of the capillary element by capillary action. The capillary element has a pore size gradient such that an average pore size of the capillary element transitions or varies from larger pores at the first end of the capillary element to smaller pores at the second end of the capillary element.

A washer liquid heating apparatus integrated into a reservoir may include an auxiliary tank which is integrally connected to the reservoir and in which a washer liquid inflowing from the reservoir is stored, and a heater assembly that is integrally attached to the auxiliary tank and heats the washer liquid stored in the auxiliary tank, wherein the heater assembly comprises a plate-type heater that is installed in a hole of the auxiliary tank to heat the washer liquid within the auxiliary tank, and wherein the plate-type heater is exposed to an inside of the auxiliary tank through the hole of the auxiliary tank such that a heating surface where heating is performed heats the washer liquid within the auxiliary tank.
