Abstract: A head-mounted device may include optical assemblies for presenting images to a user. Optical assembly positioning systems may be used to adjust the spacing between the optical assemblies to accommodate different interpupillary distances. The optical assembly positioning systems may have motors. Nose pressure sensors may be provided to detect nose pressure as optical assemblies are moved towards each other and towards nose surfaces by the motors. Motion of the optical assemblies can be halted whenever the detected nose pressure rises. The nose pressure sensors may each include an air pressure sensor and a pressure-sensing compressible air-filled chamber coupled to the air pressure sensor.

Abstract: Disclosed is a pair of glasses with inwardly biased temples that can frictionally secure the glasses over the temples of a wearer. This allows the temples to be shorter in length and eliminates the need for the temples to be secured to the ears. The biasing of the temples is achieved, in one embodiment, via torsion springs integrated into the hinges of the glasses.

Abstract: A method, an arrangement for microscopy and a microscope for three-dimensional imaging in microscopy, in which aberrations of a specimen detection radiation coming from a specimen are corrected in a detection beam path by means of a correction element and the corrected specimen detection radiation is captured in a spatially resolved form. The inventions are distinguished by the fact that a best-possible correction setting of the correction element, with which aberrations occurring at the time are reduced as much as possible, is determined; and, on the basis of the best-possible correction setting, a flawed correction setting is determined, a setting with which aberrations occurring lead to an asymmetric point spread function of the specimen detection radiation.
