Abstract: A material processing apparatus is disclosed. This material processing apparatus is particularly developed to utilize a quasi-traveling microwave to conduct heat treatment for a thread-type article like fiber, silk, artificial fiber, and artificial silk. The material processing apparatus comprises a primary waveguide tube, a microwave blocking plate, a secondary waveguide tube, and at least one microwave absorbing member disposed of in the primary waveguide tube. By such design, a microwave source supplies a microwave to the secondary waveguide tube and the primary waveguide tube, such that the microwave travels in the two waveguide tubes so as to become a quasi-traveling microwave. Therefore, in the case of a thread-type article being be fed into the primary waveguide tube via the secondary waveguide tube by a thread-type article transferring mechanism, the thread-type article is steadily and evenly heated by the quasi-traveling microwave in the two waveguide tubes.

Abstract: The present invention is generally a radio frequency apparatus for warming fluids such as IV fluids. In exemplary embodiments, a uniform warming of fluids is achieved by exposing a fluid-carrying tube to Radio Frequency (RF) energy. The RF energy may be supplied by an RF generator, which is coupled to a waveguide. The waveguide typically includes an inlet into which a fluid tube may be introduced. Inside the waveguide, a pathway may be formed wherein the fluid tube may rest in a predetermined position. In exemplary embodiments, the pathway guides the positioning of the tube along a transmission-line length of the waveguide, in a manner such that the tube gradually approaches an electromagnetic field inside the waveguide and exits at a second terminal end of the waveguide. Having absorbed energy supplied from the RF generator, the fluid inside the tube exits the apparatus warmed to a desired temperature.

Abstract: Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.

Abstract: A defrosting system includes an RF signal source, one or more electrodes proximate to a cavity within which a load to be defrosted is positioned, a transmission path between the RF signal source and the electrode(s), and an impedance matching network electrically coupled along the transmission path between the output of the RF signal source and the electrode(s). The system also includes measurement circuitry coupled to the transmission path and configured to measure one or more parameters that include voltage, current, forward signal power, reflected signal power, and S11 along the transmission path. A system controller is configured to monitor the measurements, and to modify operation of the system when a rate of change of any of the monitored parameter(s) exceeds a predetermined threshold. The impedance matching network may be a single-ended network or a double-ended network.
