  • Patent number: 11862394
    Abstract: An electrochemical capacitor (300) for use with a biofilm is presented. The electrochemical capacitor includes a first electrode (324) coupled to a first porous layer (326), a second electrode (334) coupled to a second porous layer (336); and an electrolyte (310) provided between the first porous layer (326) and the second porous layer (336). At least one of the first porous layer (326) and the second porous layer (336) has a plurality of cavities adapted to receive redox-active metabolites produced by the biofilm. Also presented is an electrochemical capacitor device, such as a skin patch that includes a support layer attached to the electrochemical capacitor (300). Also presented is a power source that includes the electrochemical capacitor (300) and a biofilm provided between the first electrode (324) and the second electrode (334) of the electrochemical capacitor (300).

  • Patent number: 11154623
    Abstract: Embodiments of the present disclosure pertain to methods of opening a lipid bilayer by associating the lipid bilayer with a molecule that includes a moving component capable of moving (e.g., rotating) in response to an external stimulus; and exposing the molecule to an external stimulus before, during or after associating the molecule with the lipid bilayer. The exposing causes the moving component of the molecule to move and thereby open the lipid bilayer (e.g., by pore formation). The external stimuli may include an energy source, such as ultraviolet light. The opened lipid bilayer may be a component of cell membranes in vitro or in vivo. The opening of the lipid bilayer may allow for the passage of various materials (e.g., active agents, such as peptide-based drugs) through the lipid bilayer and into cells. Additional embodiments of the present disclosure pertain to the aforementioned molecules for opening lipid bilayers.

  • Publication number: 20190137758
    Abstract: A pseudo light-field display uses a stereoscopic display viewed by a user, with a variable lens disposed between each eye and the display, and a half-silvered mirror disposed between each lens and the display. A focus measurement device operates through at least one half-silvered mirror with one of the variable lenses to detect focus of an eye, providing a focus output, and controlling both variable lenses. A gaze direction measurement device operates through both half-silvered mirrors to detect the gaze direction of each eye, and provides an output of the vergence or individual gaze directions of the eyes. The focus, vergence, and gaze directions are used to establish a visual focal plane, whereby objects on the display that are being gazed upon in the visual focal plane are in focus, with other objects appropriately blurred, thereby approximating a light-field display.

  • Patent number: 9550976
    Abstract: The invention provides for a method for aggregating dermal papilla cells or dermal sheath cells or a combination thereof, the method comprising: growing dermal papilla cells or dermal sheath cells or a combination thereof in suspension culture; and contacting the culture with an effective amount of an enzyme, wherein a substrate of the enzyme is an extracellular matrix molecule in the suspension culture, so as to aggregate dermal papilla cells or dermal sheath cells. The culture may be a hanging drop culture and the enzyme may be a hyaluronidase.
