A gauge having a housing formed of a polymer material and one or more electrical feedthrough pins disposed in the housing. The electrical feedthrough pins can be oriented substantially perpendicular to each other and have complex shapes.

Polymer composite vacuum components

Described herein are various embodiments of binder and slurry compositions and methods of making a solid-state battery therefrom. An solid-state electrochemical cell may include a first electrode substrate with a separator layer that is continuously interleaved in an alternating pattern with a second electrode substrate. A method of making a solid-state electrochemical cell may include applying a separator layer to a first electrode substrate and continuously interleaving folded portions of the first electrode substrate with alternating folded portions of a second electrode substrate to form an electrochemical cell.

Binder and slurry compositions and solid state batteries made therewith

A cold cathode ionization vacuum gauge includes an extended anode electrode and a cathode electrode surrounding the anode electrode along its length and forming a discharge space between the anode electrode and the cathode electrode. The vacuum gauge further includes an electrically conductive guard ring electrode interposed between the cathode electrode and the anode electrode about a base of the anode electrode to collect leakage electrical current, and a discharge starter device disposed over and electrically connected with the guard ring electrode, the starter device having a plurality of tips directed toward the anode and forming a gap between the tips and the anode.

Cold cathode ionization vacuum gauge

A cold cathode ionization gauge includes multiple cathodes providing different spacings between the cathodes and an anode. The multiple cathodes allow for pressure measurements over wider ranges of pressure. A first cathode with a larger spacing may provide current based on Townsend discharge; whereas, a second cathode having a smaller spacing may provide current based on both Townsend discharge at higher pressures and on Paschen's Law discharge at still higher pressures. A feature on the second cathode may support Paschen's Law discharge. Large resistances between the cathodes and a return to power supply enable control of output profiles to extend the pressure ranges with accurate responses and avoid output minima. Pressure measurements may be made based on currents from respective cathodes dependent on the outputs of the cathodes through the wide pressure range of measurement. The multiple cathodes may also provide measurements that avoid the discontinuities found in current outputs of the respective cathodes.
