  • A METHOD TO KEEP THE EXCITATION LIGHT SHEET IN FOCUS IN SELECTIVE PLANE ILLUMINATION MICROSCOPY
    Publication number: 20200340921
    Abstract: Keeping the excitation light sheet in focus is critical in selective plane illumination microscopy (SPIM) to ensure its 3D imaging ability. Unfortunately, an effective method that can be used in SPIM on general biological specimens to find the axial position of the excitation light sheet and keep it in focus is barely available. Here, we present a method to solve the problem. We investigate its mechanism and demonstrate its performance on a lattice light sheet microscope.

    Publication number: 20200315570
    Abstract: Methods and systems for measuring one or more properties of a soft material employ air transmitted ultrasound that is reflected from the soft material to generate a mechanical wave in the soft material. A method of measuring one or more properties of a soft material includes transmitting ultrasound through air to an interface boundary between the soft material and air. Force is applied to the soft material by reflecting the ultrasound from the soft material. A mechanical wave is generated in the soft material as a result of the force applied to the soft material. Propagation of the mechanical wave in the soft material is measured with an imaging system. One or more properties of the soft material is determined based on the measured propagation of the mechanical wave in the soft material.

  • Automated analog layout
    Patent number: 10783292
    Abstract: An automated analog layout tool creates not just one, but many electrically correct layouts from an input schematic. Designers can explore multiple layout options in a fraction of the time needed to produce just a single layout by hand. Because the tool produces layout results so quickly, parasitics are available for simulation early in the design process, further speeding the entire design cycle. The tool considers place and route concurrently.
