  • Publication number: 20240076622
    Abstract: Methods provided by the present disclosure utilize extracorporeal shockwaves, mechanical impacts and/or principles of lithotripsy to break up a tissue sample into smaller fragments—clusters of cells and/or single cells—after which a desired cellular fraction can be isolated from the sample. Devices provided by the present disclosure deploy focused and/or directed shockwaves, and/or focused and directed mechanical impacts, to break apart a tissue sample. The devices maintain the sample in a sterile, closed environment during exposure to the shockwaves or mechanical impacts. Therefore, the shockwaves and/or mechanical impacts are generated outside of a closed device and are transmitted through one or more walls of the device into its interior, where the sample is located.

  • Patent number: 11256102
    Abstract: An immersive headset device is provided that includes a display portion and a body portion. The display portion may include microdisplays having a compact size. The microdisplays may be movable (e.g., rotational) relative to the body portion and can be moved (e.g., rotated) between a flipped-up position and a flipped-down position. In some instances, when the microdisplays are flipped up, the headset provides an augmented reality (AR) mode to a user, and when the microdisplays are flipped down, the headset provide a virtual reality (VR) mode to the user. In certain implementations, the headset includes an electronics source module to provide power and/or signal to the microdisplays. The electronics source module can be attached to a rear of the body portion in order to provide advantageous weight distribution about the head of the user.
