A battery-powered scope warmer includes a heated cavity to receive the distal end of a surgical viewing instrument such as an endoscope or laparoscope. The distal end of the surgical viewing instrument is inserted into the cavity in the housing through one or more flexible flaps in the upper portion of the housing. A heating pad forms a curved tray that receives the distal end of the instrument. The flaps enable the distal end of the surgical viewing instrument to be inserted into, or removed from, the cavity in the housing through one or more slits. A de-fogging sponge in the cavity may be moistened with a de-fogging fluid, and one or more absorbent pads may be disposed on the upper portion of the housing for removing excess fluid from the tip of the surgical viewing instrument. The entire warmer, including the batteries, may be disposable.

An integrated circuit is provided having an active circuit. A heating element is adjacent to the active circuit and configured to heat the active circuit. A temperature sensor is also adjacent to the active circuit and configured to measure a temperature of the active circuit. A temperature controller is coupled to the active circuit and configured to receive a temperature signal from the temperature sensor. The temperature controller operates the heating element to heat the active circuit to maintain the temperature of the active circuit in a selected temperature range.

The present invention relates to smoking articles, for example electronic cigarettes (h referred to as “e-cigarettes”), and fluid reservoirs for use therewith or therein.

An electronic vapor provision system is provided including a pressure drop or air flow sensor for monitoring inhalation by a user through the electronic vapor provision system; and a control unit for detecting the start and end of inhalation based on readings from the sensor. The control unit is configured to monitor the cumulative period of inhalation (Ti) over a predetermined window (Tw); and transfer the electronic vapor provision system to a sleep mode if the cumulative period (Ti) exceeds a predetermined threshold (Th).

A method of manufacturing an aerosol provision apparatus for heating smokable material to volatilise at least one component of the smokable material, and said aerosol provision apparatus is described. The method comprises providing a heater arrangement (23) for heating smokable material contained in use within the apparatus (1), the heater arrangement comprising at least a first heating zone (220) and a second heating zone (230) for heating different portions of the smokable material, providing a temperature sensor (320, 330) for each of the first and second heating zones, each temperature sensor for providing temperature measurements to be used as input temperature measurements for a temperature control loop, the control loop for controlling the heater arrangement to heat its associated respective heating zone to a target temperature based on the input temperature measurements acquired by the associated temperature sensor, and positioning each temperature sensor in its associated heating zone at a respective position selected so that if the heating arrangement were to heat the first and second heating zones so that the temperature sensors measure the same pre-selected target temperature, a temperature gradient across the length of the heating zones between the temperature sensors would be optimised as being substantially flat.

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, and an aerosol passage are interconnected.

An electronic cigarette includes a liquid supply including liquid material, a heater operable to heat the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol, a wick in communication with the liquid material and in communication with the heater such that the wick delivers the liquid material to the heater, at least one air inlet operable to deliver air to a central air passage upstream of the heater, and a mouth end insert having at least two diverging outlets. The electronic cigarette can also include an air flow diverter which directs incoming air away from a heating zone of the heater.

A heatable glazing comprising a pane of glazing material with a first portion delimited by a first and a second bus bars wherein a voltage VI is applied and a second portion of the pane in need of rapid heating delimited by the second bus bar and a third bus bar wherein a voltage V2 is applied. The voltage VI is converted into a voltage V2 within the second portion by an electrical converter DC/DC.

A device (100) for heating an aerosol-forming substrate includes a heater (160), a receptacle inlet (143) and outlet (147), and an air inlet channel (170). The heater includes a heating element, an internal surface, and an external surface. The internal surface defines at least a portion of a receptacle (140) configured to receive the aerosol-forming substrate or a cartridge comprising the aerosol-forming substrate. The receptacle inlet is in communication with, and upstream of, the receptacle. The receptacle outlet is in communication with, and downstream of, the receptacle. The air inlet channel is in communication with an ambient environment and the receptacle inlet. The air inlet channel defines a tortuous path between the ambient environment and the receptacle inlet. The air inlet channel is positioned relative to the heater to cause air in the tortuous path to be heated by the heater.

A customizable device may include a first inhalation device and a second inhalation device, each including a mouth end portion and an upstream end portion. In a storage configuration, the mouth end portion of at least one of the first inhalation device or the second inhalation device is removably coupled to the other inhalation device. In an active configuration, the upstream end portion of at least one of the first inhalation device or the second inhalation device is removably coupled to the other inhalation device. A connector hub may couple the inhalation devices.
