Abstract: The invention relates to a system and method for verifying the presence and vital signs of pilots in a cockpit of an airplane. The system uses autonomous short-range active communication equipment and, in particular, a central control and actuation unit located in the cockpit of the airplane and personal control units worn by the pilots that wait to receive a request signal from the central control and actuation unit to determine the absence of the pilot from the cockpit, based on the intensity of the request signal received, and whether the pilots' vital signs are anomalous, using a heart rate sensor. In the event of detecting an anomalous situation, an alert is sent to the central control and actuation unit, which executes a certain action in accordance with the specific alarm detected.

Abstract: A composition for cleaning a medical instrument having a surface at least partially covered by a biofilm. The composition may include a first enzyme having a weight of less than about 10% of the total weight of the composition, a second enzyme having a weight of less than about 10% of the total weight of the composition, and a surfactant having a weight less than about 10% of the total weight of the composition. The second enzyme may be different from the first enzyme. Additionally, the composition may have a pH ranging from about 4 to about 12, and the composition may be configured to remove greater than about 90% of the biofilm from the medical instrument in less than about 10 minutes.
