This invention provides an assembly comprising a sensing electrode and a counter electrode in contact with a membrane body formed from a solid polymer electrolyte system comprising a fluorinated polymer matrix and a charge carrying component which is dispersed in the matrix the electrodes and membrane being housed in a housing having a gas diffusion barrier through which gas may flow. The compositions include a polythioether and, in at least some cases, can be sprayable and fuel resistant even when substantially free of volatile organic compounds. The equivalent series resistance of the multilayer capacitor can be increased while suppressing an increase in the equivalent series inductance resulting in improved noise grounding. The reference samples of the second subset may be utilized by a second search pattern in the motion estimation of the current block.
