Abstract: Example computer-implemented methods, media, and systems for isolating an emergency within process systems of a hydrocarbon processing facility are disclosed. One example method includes receiving a drawing of multiple process systems of a hydrocarbon processing facility. A respective identifier is assigned to each of multiple drawing vectors, where each of the multiple drawing vectors corresponds to a respective component of the multiple process systems. The multiple drawing vectors are coded based on the assigned identifiers. One or more drawing vectors connected to a location of the emergency are determined from the multiple coded drawing vectors. One or more connections between the one or more drawing vectors and the location of the emergency are identified. A first isolation valve for isolation of the emergency is determined from one or more isolation valves corresponding to the one or more connections. The first isolation valve is provided for the isolation of the emergency.

Abstract: Methods and apparatus for visualizing and manipulating three-dimensional digital dental models and related methods and apparatus for dental treatments are disclosed. In one aspect, a method for visualizing and manipulating a three-dimensional digital dental model may comprise viewing the three-dimensional digital dental model and using hand gestures to instruct a computer to manipulate one or more teeth in the digital dental model. In other aspects, a dental treatment method may comprise viewing a three-dimensional digital model, using hand gestures, a conventional keyboard, and/or a conventional mouse to instruct a computer to manipulate one or more teeth in the digital model to generate a three-dimensional digital model of a modified arrangement of the subject's teeth, and fabricating one or more dental aligners configured to reposition the subject's teeth into the modified arrangement. Viewing may comprise stereoscopically viewing a digital dental model.

Abstract: Methods, devices and systems for digitizing a patient's arch and manipulating the digital dental arch model. In one variation the methods includes producing a physical arch model for the patient's arch, separating the physical arch model into a plurality of arch model components, mounting the arch model components on a scan plate, capturing one or more images of the arch model components, and developing digital representations of the arch model components using the captured one or more images.
