  • Apparatus for monitoring an electrolyte
    Patent number: 5074988
    Abstract: An electrode, preferably of a conductive polymer, has on its surface, preferably over all of its surface, an ion exchange material, preferably of significant thickness. Such a coated electrode may be used for sensing the presence of measuring the concentration of an ionic species, or for removal from or release of an ionic species into an electrode.
    Type: Grant
    Filed: May 14, 1990
    Date of Patent: December 24, 1991
    Assignee: Raychem Corporation
    Inventors: Eric D. Nyberg, Ken A. Klingman, Jeff Curtis, Ray F. Stewart
  • Method for detecting and locating an electrolyte
    Patent number: 5049247
    Abstract: A method for monitoring for the presence of an electrolyte and for locating the electrolyte upon its presence uses a system comprising an electrically conductive locating member and an electrically conductive source member, between which an electrical connection is made upon the presence of the electrolyte. The locating member and/or the source member comprises (i) an electrode and (ii) an ion exchange material which is in electrical and physical contact with and substantially entirely surrounds all surfaces of the electrode; the ion exchange material having an ionic resistance which depends upon the concentration of a chemical species in the electrolyte. Upon the presence of the electrolyte, a connection to the locating member is made effective at a first point whose location is defined by the presence of the electrolyte.
