  • Publication number: 20220209277
    Abstract: The present disclosure relates to an electrical energy storage apparatus. The apparatus has an interpenetrating, three dimensional periodic structure formed from an ionically conductive solid electrolyte material having a plurality of interpenetrating, non-planar channels. The interpenetrating, non-planar channels are made up of a first plurality of channels filled with an anode material, a second plurality of channels adjacent the first plurality of channels and interpenetrating with the first plurality of channels, and filled with a cathode material, and a third plurality of channels adjacent to, and interpenetrating with, one of the first and second pluralities of channels, and filled with a material to form a separator. The first, second and third channels form a spatially dense, three dimensional structure. A first non-flat current collector layer is incorporated which is in communication with the first plurality of channels, and which forms a first electrode.

  • Patent number: 10962566
    Abstract: Test and measurement probes include a body, an adjustable member moveably coupled to the body and having a changeable position relative to the body, and a transducer subsystem structured to measure the position of the adjustable member and configured to output a position signal indicative of the position of the adjustable member. A change in the position of the adjustable member causes a change in an electrical characteristic of the probe. A position-dependent correction factor may be used to correct the change in the electrical characteristic. Methods of compensating for a change in a response of a test and measurement system include monitoring a position sensor output to detect a position change of a first part of a probe relative to a second part, determining that the position sensor output value has crossed a boundary value between a first and second range, and applying a compensation factor corresponding to the second range to modify the response of the system.
