Abstract: A method for automated spacecraft design includes receiving mission parameters provided by a client for spacecraft design, generating one or more concept designs based on the received mission parameters, each concept design including one or more components selected for each subsystem included in a designed spacecraft, for each concept design, generating a CAD model including a collection of CADs representing structures of the one or more components selected for each subsystem included in the designed spacecraft, performing a series of analyses or simulations to evaluate a performance of the CAD model, and generating a digital twin representing a virtual representation of the designed spacecraft.

Abstract: To stabilize the inserted position of an endotracheal tube and to protect it against bite-damage, a bite-block of relatively rigid tough plastic has integrally connected front-edge flanges for overlying the upper and the lower lips of a patient for attachment thereto as by strips of adhesive tape, and has a forwardly extending vertically-on-edge flange for attachment thereto of the endotracheal tube as by adhesive tape wrapped therearound.
