  • Publication number: 20250003851
    Abstract: Described is an apparatus for measuring rheological and electrical properties of a sample. The apparatus includes a first geometry comprising a first and a second stationary element each being electrically conductive and having a surface disposed to face the surface of the other stationary element across a gap. The first and second stationary elements are electrically isolated from each other. The apparatus further includes a second geometry comprising a rotatable element disposed in the gap and configured to rotate between the first and second stationary elements. The rotatable element is electrically conductive such that a first electric field is generated between the first stationary element and the rotatable element and a second electric field is generated between the rotatable element and the second stationary element in response to application of a voltage difference applied across the first and second stationary elements.

  • Patent number: 5714750
    Abstract: A miniature scan engine for scanning a beam of monochromatic (laser) light across a bar code and receiving return light at a detector that provides electrical signals representing the code, utilizes an integral assembly of a laser (laser diode), the detector and a light collector mounted on flexures and rotated so as to scan the beam and receive the return light from the code. The collector is a body of material transmissive at the laser wavelength. The body presents an orientable surface so that the return light is incident at or close to perpendicular to the surface. In the body, parallel to the surface, is a volume hologram grating having Bragg planes arranged in rings around a center region in alignment with the detector. The angles of the Bragg planes vary progressively and decreases in a direction toward the center region so that light incident on the collector at angles of incidence, which vary from perpendicular to the surface by about + or -5.degree.
