Abstract: Disclosed is a changing device for optical components in a microscope. The changing device includes an optical component having a flat surface. The changing device further includes a carrier for inserting and/or holding the optical component. The changing device further includes a receptacle for holding the carrier in an optical path of the microscope. The carrier has bearing surfaces for the flat surface of the optical component and positioning surfaces located in the same plane, which are not covered by the optical component, when inserting the latter. The receptacle has bearing surfaces for contact with the positioning surfaces and first attachment means for attaching the carrier positioned on the receptacle in order for the positioning surfaces to act upon the bearing surfaces.

Abstract: An apparatus (and a corresponding operation method) for automated maskless painting of an external paint on a complex surface using a coloring agent, wherein the complex surface is part of an aircraft. The apparatus comprises a multi-axis robot comprising at least one applicator for the coloring agent, wherein the at least one applicator is configured to apply the coloring agent to the complex surface using a coloring agent ejection technology.

Abstract: A system and method configured to monitor biological data. The system includes a biosensor assembly for processing biological data of a living body. The biosensor assembly comprises a sensor configured to be coupled to a wearable item, for instance a cap worn on the head of a user. The sensor is positioned on the wearable item to gather raw biological data from the body of the user, when the wearable item is worn on the body of the user. The assembly further comprises a controlling unit configured to interpret raw biological data received from the sensor and interpret raw biological data by computing a value representative of a physiological condition of the body of the user. The controlling unit compares the representative value to a threshold value stored in memory to characterize the physiological condition of the user and alerts the user.

Abstract: A method of producing structured wafers guarantees that the edge of the wafer will be protected from attack by an aggressive etchant medium without applying a photoresist to the edge and without using additional mechanical measures. In a type of negative process, a passivation layer is applied to the areas that are not to be structured, including the edge area of the wafer.
