Abstract: A computer system optionally displays a user interface object that reveals content based on whether the content is private or shared. A computer system optionally displays a user interface object that includes shared content based on whether participants have entitlement to the content. A computer system optionally displays a sharing indicator that indicates that the respective content is shared with one or more other participants.

Abstract: In some embodiments, a computer system facilitates depth conflict mitigation for a virtual object that is in contact with one or more physical objects in a three-dimensional environment by reducing visual prominence of one or more portions of the virtual object. In some embodiments, a computer system adjusts the visibility of one or more virtual objects in a three-dimensional environment by applying a visual effect to the one or more virtual objects in response to detecting one or more portions of a user. In some embodiments, a computer system modifies visual prominence in accordance with a level of engagement with a virtual object.

Abstract: Injection devices with ergonomic enhancements are disclosed. Generally, the injection devices include large oversized grips, including flanges at the base end of the device for enhanced stability. Push-type and squeeze-type devices are described, as well as manual injectors and auto-injectors. Such injection devices are useful for delivering a fluid (e.g. medication) to a patient.

Abstract: Processes and devices for delivering a fluid by chemical reaction are disclosed. A chemical reaction is initiated in a reaction chamber to produce a gas, and the gas acts upon a piston to deliver the fluid. An exemplary device may include an upper chamber, a lower chamber, a fluid chamber, a piston between the lower chamber and the fluid chamber, and a one-way valve between the upper chamber and the lower chamber.

Abstract: Processes and devices for delivering a fluid by chemical reaction are disclosed. A chemical reaction is initiated in a reaction chamber to produce a gas, and the gas acts upon a piston to deliver the fluid. Preferred devices typically include an upper chamber, a lower chamber, a fluid chamber, a piston between the lower chamber and the fluid chamber, and a barrier between the upper chamber and the lower chamber. When the barrier is broken, reagents in the upper chamber and the lower chamber are mixed together to generate the gas.

Abstract: Chemical engines and processes for their use and construction are described. The chemical engines can provide powerful and compact devices, especially autoinjectors for the rapid, powered injection of viscous medicines. Novel formulations and designs of chemical engines and delivery technologies employing the chemical engines are described.

Abstract: An apparatus (10) includes a body (2), a plunger (5), and an occlusion (4). The body is able to hold one or more medical substances therein. The body defines a longitudinal axis extending therethrough. The plunger is positioned within a portion of the body and is able to axially advance along the longitudinal axis. The plunger also defines an opening extending therethrough. The occlusion is able to extend through at least a portion of the opening of the plunger so that the plunger and the occlusion fluidly divide the body. The plunger is able to exert a first outward force against the body. The plunger is able to exert a second outward force against the body when the occlusion has been removed where the second outward force is less than the first outward force.
