In one aspect, apparatus is provided for generating an inhalable medium. The apparatus has a container for holding a liquid and a heater for volatilizing liquid held in the container. The apparatus further has a chamber for receiving a material. The apparatus has an outlet. In use liquid volatilized by the heater passes, in the form of at least one of a vapor and an aerosol, through material received in the chamber to thereby entrain one or more constituents from the material to produce the inhalable medium which passes out of the outlet.

Inhalator and cartridge thereof

An apparatus comprising a heater configured to heat smokeable material to volatilize at least one component of the smokeable material, wherein the heater is elongate and comprises a plurality of independently controllable heating regions arranged sequentially along a longitudinal axis of the heater.

Heating smokeable material

An apparatus comprising a heater configured to heat smokable material to volatilize at least one component of the smokable material, wherein the heater is elongate and comprises a plurality of independently controllable heating regions arranged sequentially along a longitudinal axis of the heater.

An apparatus comprising a smokable material heater, configured to heat a first region of smokable material to a volatizing temperature sufficient to volatize a component of smokable material and to concurrently heat a second region of smokable material to a temperature lower than said volatizing temperature but which is sufficient to prevent condensation of volatized components of the smokable material. A method of heating smokable material is also described.

Heating smokable material

An apparatus comprising a heating chamber for heating smokable material, the apparatus being operable in a first configuration to allow a gaseous flow between an interior of the chamber and an exterior of the chamber and operable in a second configuration to prevent the gaseous flow by hermetic sealing of the chamber.

Optimized directional MIMO antenna system

Systems and methods for a dual-band antenna and methods for manufacturing the same are described. One system and method includes a plurality of antenna elements. Groups of the antenna elements cooperate to form directional antennas at various frequencies. Using an active element, configurable at different frequencies and reflectors tuned to different frequencies, directed transmission or direction of positive gain for the antenna system is achieved.

Dual-band antenna

A method for radio communication in a wireless local area network including at least one transceiver equipped with an antenna with a controlled directivity pattern, according to which, in addition to the assignment in advance of the threshold value of communication quality Hcorresponding to the minimum pre-specified communication quality, the current value of communication quality Qis periodically determined based on the signal being received, the threshold value of the communication quality H(corresponding to the pre-specified maximum communication quality) is also additionally assigned in advance. With the current value of communication quality Qbeing grater than or equal to the upper threshold value H, the information exchange is continued, while with the current communication quality value Qbeing less than the upper threshold value H, but greater than or equal to the lowest threshold value H, the information exchange is also continued and the procedure for the optimization of antenna beam direction is carried out after a pre-specified time interval T.

Radio communication method in a wireless local network

Systems and methods for a directional antenna and methods for manufacturing the same are described. One system and method includes a plurality of antenna elements. Groups of the antenna elements cooperate to form a directional antenna. In one configuration, a first element is configured as a driven element and a second element is configured as a delayed element. The elements are separated by a distance such that an RF signal radiated from the driven element constructively combines with a delayed RF signal radiated by the delay element. In another configuration, the second element can be configured as the driven element and the first element configured as the delayed element.

Configurable directional antenna

The invention relates to antenna systems used in local wireless communications networks. The antenna system includes planar directional antennas (), each of which is made as a dielectric plate (), with an active element () of the antenna () mounted on said plate. The surface of the plate () that faces the active element is metallized and serves as a reflector () of the antenna (). The plates () are interconnected along their edges in such a way as to form lateral facets of a hollow frame () of the device. The end face () is made as a dielectric plate () with the external surface metallized and can also contain an active element () of the antenna (). An antenna commutation switch () connected to a switch control unit () and to active elements () of the antennas () is mounted on the inner surface of the end face () of the frame (). Active element () is mounted on said plate by means of pins cut in the body of the active element () and bent during mounting. This invention permits to manufacture structurally simple and inexpensive antennas and antenna systems based on printed circuits and to exclude manual operations from the manufacturing and assembly of said antennas and antenna systems.
