Abstract: A method includes processing an object in a cavity by applying radio frequency (RF) energy to the cavity. A first plurality of frequencies is identified, characterized in that a time derivative of a value indicative of a dielectric response of the cavity to RF energy at frequency of the first plurality of frequencies is larger than a first threshold. More energy is applied at frequencies of the first plurality of frequencies than at other frequencies.

Abstract: An apparatus for applying RF energy to process an object may include at least one controller configured to receive EM feedback-related values from an energy application zone, each of the values being associated with a respective MSE. The controller may also be configured to identify a change in one or more of the EM feedback-related values within a period of time; adjust the RF energy application based on the change in the EM feedback-related values identified, and cause application of RF energy to the energy application zone.

Abstract: Method and apparatus for the alignment of optical interconnections between at least one optical data transmission point and at least one corresponding optical data receiving point. A collimated beam of data carrying light is polarized through an electrically-controlled light polarizer, such as a spatial light modulator or a liquid crystal, which comprises an array of pixels. A focused beam of the data-carrying light, emitted from the light polarizer, is obtained on the receiving point, by individually controlling the polarization of each pixel, and deflecting the direction of the collimated beam when emitted from the light polarizer, until a predetermined value of an electrical signal (current and/or voltage) representing the level of alignment is obtained. The collimated beam is further continuously and/or adaptively aligned by determining a desired current and a threshold current and/or voltage produced by an optical sensor at the receiving point.
