  • Publication number: 20240142281
    Abstract: An apparatus includes a sensing region. A flexible membrane positioned in the sensing region defines a plane, a radial center, and a central axis extending perpendicularly relative to the plane at the radial center. The membrane deforms along the central axis and along a lateral dimension using at least a property of fluid (e.g., pressure or density) in the sensing region. The lateral dimension is transverse to the central axis. An optical feature changes a visual state in response to deformation of the membrane along the lateral dimension. A camera is positioned to view the optical feature and capture images of the optical feature.

  • Publication number: 20080116927
    Abstract: Contact tip structures are fabricated on sacrificial substrates for subsequent joining to interconnection elements including composite interconnection elements, monolithic interconnection elements, tungsten needles of probe cards, contact bumps of membrane probes, and the like. The spatial relationship between the tip structures can lithographically be defined to very close tolerances. The metallurgy of the tip structures is independent of that of the interconnection element to which they are attached, by brazing, plating or the like. The contact tip structures are readily provided with topological (small, precise, projecting, non-planar) contact features, such as in the form of truncated pyramids, to optimize electrical pressure connections subsequently being made to terminals of electronic components. Elongate contact tip structures, adapted in use to function as spring contact elements without the necessity of being joined to resilient contact elements are described.
