US Classification:

436 5, 422 8202, 427 58

Abstract:

A sensor for measuring gas permeability of a test material, comprising: an electrically conductive sensing element that comprises a water and/or oxygen sensitive material, wherein the reaction of said material with water or oxygen when the sensing element is contacted with water and/or oxygen results in a change in the electrical conductivity of the sensing element, and two electrodes electrically connected to the sensing element.

Abstract:

Inductors that generate a reduced spurious electric-field. One example can provide an inductor where the terminals of the inductor are located at positions that reduce the spurious electric field by determining the types of signals conveyed at the terminals of the inductor and then selecting locations for the terminals based on that determination. For example, where a dynamic differential signal is applied to the inductor, the terminals of the inductor can be positioned near a physical center of the inductor.
