  • Publication number: 20230364605
    Abstract: Provided are methods of engulfing particles into droplets. The methods use a microfluidic device comprising a droplet generator and a chamber, the chamber comprising a liquid medium disposed on a voltage supply electrode and a ground electrode. The methods comprise dispensing a particle and a droplet into the liquid medium, and dielectrophoretically trapping the particle and the droplet using the voltage supply electrode and the ground electrode. The methods further comprise engulfing the particle into the droplet, wherein the engulfing comprises increasing a supply voltage between the voltage supply electrode and the ground electrode, thereby moving the droplet toward the voltage supply electrode and engulfing the particle into the droplet. In certain embodiments, the methods further comprise modifying the engulfed particle, assessing the engulfed particle, or both.

  • Patent number: 10859517
    Abstract: Single X-ray grating differential phase contrast (DPC) X-ray imaging is provided by replacing the conventional X-ray source with a photo-emitter X-ray source array (PeXSA), and by replacing the conventional X-ray detector with a photonic-channeled X-ray detector array (PcXDA). These substitutions allow for the elimination of the G0 and G2 amplitude X-ray gratings used in conventional DPC X-ray imaging. Equivalent spatial patterns are formed optically in the PeXSA and the PcXDA. The result is DPC imaging that only has a single X-ray grating (i.e., the G1 X-ray phase grating).

  • Patent number: 10645091
    Abstract: The embodiments provide for binding files to an external drive, a secured external drive, or portable data locker. The files are bound in order to help restrict or to prevent access and modification by certain computers or users. Computers or users that are authorized or within the authorized domain are permitted full access. The files stored on the external drive may be bound in various ways. The files may be encapsulated in a wrapper that restricts the use and access to these files. The bound files may require execution of a specific application, plug-in, or extension. A computer may thus be required to execute program code that limits the use of the secured files. In one embodiment, the external drive provides the required program code to the computer. In other embodiments, the required program code may be downloaded from a network or provided by an external authority.
