Abstract: This application generally relates to deformable elastomeric conductors and differential signaling transmission techniques. According to one embodiment, a deformable elastomeric conductor is configured to transmit electrical signals. It comprises: an elastomeric polymer matrix; and conductive filler material uniformly dispersed in the elastomeric polymer matrix sufficient to render the material electrically conductive. The conductive filler material may include substantially non-entangled particles having an aspect ratio sufficiently large to enable the particles to substantially remain in contact and/or in close proximity with adjacent particles so as to maintain conductive pathways in the material when the material is subjected to deformation up to and exceeding 10% strain. Thus, over a transmission distance of an electrical signal through the conductor, the transmission does not suffer greater than about 3 dB of signal attenuation when subjected to the deformation.

Abstract: The present disclosure relates to additives for electrolytes and preparation of aluminum-based, silicon-based, and bismuth-based additive compounds that can be used as additives or solutes in electrolytes and test results in various electrochemical devices. The inclusion of these aluminum, silicon, and bismuth compounds in electrolyte systems can enable rechargeable chemistries at high voltages that are otherwise unsuitable with current electrolyte technologies. These compounds are so chosen because of their beneficial effect on the interphasial chemistries formed at high potentials, such as 5.0 V class cathodes for Li-ion chemistries. The application of these compounds goes beyond Li-ion battery technology and covers any electrochemical device that employs electrolytes for the benefit of high energy density resultant from high operating voltages.

Abstract: An RF system comprising of outputs to an electronically scanning antenna for radiating electromagnetic energy; at least one waveform generator; two multiphase phase-locked loops integrated with the waveform generator, the phase locked loops operating to provide multiple shifted phases to a waveform. Optionally, the two multiphase phase-locked loops may each be divided down by a bank of frequency dividers to further increase the number of phase shifts. The phases generated from each multiphase phase-locked loops are selected with multiplexers then mixed together. These upper or lower sidebands are then mixed with the up converted waveform which results in a phase shift for the waveform associated with each antenna element.
