Abstract: A system supporting perioperative workflow includes a backend system with at least one database; at least one application configured with the database(s); and at least one user interface (UI) mechanism supporting a plurality of role-specific graphical user interfaces (GUIs) to the backend system. The backend system maintains an authoritative version of perioperative workflow information for each of a plurality of patients. One or more devices are configured with at least some of the role-specific GUIs, and operably connected to and interact with the backend system via the UI mechanism(s). Each device is configured to: receive and display perioperative workflow information from the backend system in a role-specific GUI on the device; and to send perioperative workflow information to the backend system via the role-specific GUI on the device.

Abstract: An improved method for aligning a plurality of optical elements in an optical device, includes: placing at least one optical element in a beam path; fixing the optical element in place without substantially compensating for errors in optical alignment; placing at least a one optical alignment element (OAE) in the beam path; and aligning the beam path to a desired beam path by adjusting the OAE. The alignment of the beam path substantially compensates for cumulative alignment errors in the beam path. The method increases the ease of manufacturing of optical devices and lowers the cost of manufacturing. The tolerances of the placement of optical elements are increased, and the optical element does not need special features for alignment.
