Abstract: A thermally conductive electromagnetically absorbing material includes a plurality of particles dispersed in a binder. The plurality of particles can have a particle size distribution having at least three peaks, where at least a majority of particles within a half width at half maximum of one, but not the other ones, of the at least three peaks are at least partially coated with an electromagnetically absorbing coating. The plurality of particles can include pluralities of first and second particles where a total number of the first particles is at most 1% of a total number of the first and second particles and where the first particles are more electromagnetically absorbing than the second particles. Films, molded articles and systems including the thermally conductive electromagnetically absorbing material are described.

Abstract: Wireless connectors and communication systems are described including a first communication device configured to emit a modulated signal, a second communication device configured to receive the emitted modulated signal and a waveguide disposed between the first and second communication devices and configured to wirelessly receive the emitted modulated signal from a first end of the waveguide, guide the received signal from the first end to an opposite second end of the waveguide, and wirelessly transmit the guided signal from the second end to the second communication device. In some embodiments, the telescopic waveguide includes a plurality of guiding sections, each guiding section being configured to slide within or over an adjacent guiding section inwardly to reduce a length of the telescopic waveguide and outwardly to increase the length of the telescopic waveguide.

Abstract: A wireless connector is disclosed that includes a first communication device configured to wirelessly transmit, by radiative coupling, a modulated signal including a carrier signal modulated with a digital signal. The wireless connector also includes a second communication device configured to receive the modulated signal. The first and second communication devices are coupled to one another through at least one wired connection that carries a signal used to demodulate the modulated signal.
