  • Publication number: 20240315238
    Abstract: An automated bioreactor system for decellularizing an organ includes a main chamber for containing the organ. The system further includes a reagent chamber containing a liquid phase reagent. A reagent conduit delivers the liquid phase reagent to the main chamber, and a perfusion conduit delivers the reagent from the reagent outlet in the main chamber into the organ. A perfusion pump drives the flow of the reagent. A perfusion pressure sensor detects a pressure of the flowing reagent. A control system controls the perfusion pump to drive the flow of the reagent based on a received input representative of a desired pressure and a received input of the detected pressure. The control system may automatically perform all of the steps of a decellularization protocol based on sensor input. An automated waste decontamination system may also be provided.

  • Publication number: 20240307224
    Abstract: Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

  • Patent number: 12064684
    Abstract: A handheld controller may include controls that are actuatable by a user. The handheld controller may further include one or more sensors that are configured to detect an object in proximity to certain controls, and/or that sense a grip or position of a hand on a handle portion of the controller. Based on data from a sensor(s), certain controls may be enabled and/or disabled. The sensors may therefore be used to determine which controls are being used or are intended to be used, and/or which controls are likely accessible or inaccessible to the user based on sensor data, and to cause one or more controls of the handheld controller to be enabled and/or disabled accordingly.

  • Patent number: 12067074
    Abstract: Disclosed herein are embodiments of a system and method for the dynamic provisioning of static content. In one embodiment, information presented on a content delivery system can be refreshed based on information published on a content management system. One embodiment can interface the content delivery system and the content management system at the page level. More specifically, content dependencies across pages employing the same content or portion(s) thereof can be tracked in a timely, accurate manner. Upon receiving a notification of a change to the content or a portion thereof from the content management system, a content generation system may operate to determine, based on the dependencies, what pages are affected by the change and, based on the determination, dynamically regenerate any and all affected pages. The regenerated pages may then be stored and/or pushed to the web tier for delivery to end users.
