Abstract: The present invention provides a process for sanitizing an object. The process comprises: (i) placing the object to be sanitized in a substantially enclosed environment, the environment being at atmospheric pressure when the object is placed therein, (ii) providing a gaseous chlorine dioxide vapour in the environment, and (iii) exposing the gaseous chlorine dioxide vapour to the object to sanitize the object. The process includes maintaining a pressure in the environment at substantially atmospheric pressure.

Abstract: A symptom mapping system and method may be used to map the simultaneous location and intensity of symptoms (e.g., pain) experienced by a user (e.g., a patient). The symptom mapping system and method is capable of displaying one or more body representations with symptom representations representing both the location and intensity of the symptoms. The symptom mapping system and method allows the user to delineate one or more user-defined symptom regions on the body representation with the symptom representations to form a symptom map. The symptom mapping system and method may also allow the user to vary the intensity represented by the symptom representations as the user delineates the user-defined symptom region(s).
